Consumer Groups Criticize Poultry Inspection Proposal




Three more leading consumer groups weighed in this week on the debate over a controversial plan to revamp poultry inspection by shifting greater responsibility to companies.  

The Center for Science in the Public Interest, Consumer Federation of America, and Consumers Union each sharply criticized the proposal in their comments filed before the Tuesday deadline, which had been pushed back a month in response to sharp criticism raised by the Government Accountability Project, Food & Water Watch, and poultry inspectors.

While each group acknowledged that modernizing the system is a commendable goal, all three expressed significant concerns about the plan to expand the HACCP Based Inspection Models Project (HIMP). The model reduces the number of inspectors from USDA's Food Safety and Inspection Service (FSIS) on duty and largely turns over physical inspections to company employees, while allowing plants to significantly speed up their production lines.

FSIS says expanding HIMP would focus inspectors on food safety tasks rather than cosmetic surveillance, save taxpayers around $90 million over three years, and each year prevent 5,200 foodborne illnesses, mostly from Salmonella. The chicken and turkey industries strongly support the measure and USDA estimates it will save the industry $250 million annually. But consumer groups question whether HIMP would actually improve food safety.   RawChickenBody.jpg  

"For years the poultry industry has operated under a system that allows for far greater levels of contamination than are acceptable to consumers," read CSPI's comments, submitted by staff attorney Sarah Klein. "FSIS should have reducing Salmonella and Campylobacter in poultry as the central tenet behind its changes, and should apply systems that monitor and measure contamination rates."

Both bugs remain a big problem for food safety regulators. Despite a greater focus on food safety, illness rates have not improved in a decade.

In their comments to USDA, CFA pointed to data showing high levels of contamination for retail poultry products. In 2007, CDC's National Antimicrobial Resistance Monitoring System found that nearly half of raw chicken breasts were contaminated with Campylobacter. In 2010, Consumer Reports found that 62 percent of whole broiler chickens purchased in 22 states were contaminated with Campylobacter; 14 percent carried Salmonella.    

Echoing concerns raised by other consumer groups, CSPI said that HIMP's lack of specific requirements for microbiological testing is a "grave error." Under HIMP, plants design their own testing plans, which are only required to sample before and after chilling the birds, and CSPI is concerned the variability in testing plans between plants will make testing data harder to analyze.

CSPI and CFA both suggest that the agency adopt a uniform testing system with a required testing frequency so that each plant's performance can be monitored as any changes are made.

"CSPI believes strongly and without reservation that the testing program described in the proposal is inadequate to protect public health," read the comments. "Measuring the effectiveness of process controls is best accomplished by standardized, mandatory sampling across the industry. Sampling and testing at key points during processing ensure that the establishment's HACCP plan is operating effectively to control pathogens."

The group strongly recommended that FSIS first adopt its testing recommendations and then move to modernization with a phased-in approach, while studying the changes against baseline data to make sure that changes are not negatively impacting food safety.

CSPI and CFA also warned against removing Salmonella performance standards, a move the groups said could expose consumers to more contaminated poultry.

In their comments, CFA specifically questioned whether the data FSIS relies on to claim that HIMP plants perform better than non-HIMP plants might be skewed. CFA noted that up until last year, FSIS did not even systematically test for Campylobacter in poultry plants, so the agency has very limited data on the pathogen.

"FSIS should postpone implementation of its proposal until it has collected additional data on Campylobacter and is better able to estimate the impacts of its proposal on reducing the pathogen," read the comments, submitted by Chris Waldrop, the director of CFA's Food Policy Institute. "CFA would expect that any subsequent analysis should demonstrate a respectable decrease in Campylobacter (and Salmonella) before the agency would move forward."

Consumers Union also slammed the fact that line speeds would be allowed to bump up to 175 birds per minute, from the current 145 bpm limit.

"Line speeds should not be increased, especially not in conjunction with efforts to remove increasing numbers of inspectors from the plants. This combination will lead to more defective birds going unnoticed and appearing in the U.S. supermarkets," read the comments, submitted by CU fellow Michelle Shaefer and senior scientists Michael Hansen.

CU said it "seriously questions the premise that speeding up the processing lines will not negatively impact food safety."

All three groups urged FSIS to mandate training requirements for company inspectors, who would largely take over the roll of sorting out diseased or defective carcasses. CSPI called the lack of training requirements in the proposed plan "unacceptable."

"The training should be at least comparable to the training received by FSIS inspectors who currently conduct sorting activities, and plant sorters should be certified as having met the standards of the training prior to assuming any carcass sorting activities," said CFA in its comments.

NYC mayor proposes ban on sugary drinks larger than 16 ounces








(Credit: CBS News)
(CBS News) Mayor Michael Bloomberg has put big beverages on notice in New York City. His administration announced Wednesday a proposed ban on the sale of sodas and sugary beverages larger than 16 ounces at restaurants, delis, movie theaters, stadiums and street carts.


Study: Sugary drink each day ups men's heart disease risk by 20 percent
Sugar should be regulated like alcohol, tobacco, commentary says
60 Minutes: Is sugar toxic?


CBS New York reports the ban will apply to bottled drinks as well as fountain sodas, and restaurants and venues that don't comply can face a $200 fine.


"Obesity is a nationwide problem, and all over the United States, public health officials are wringing their hands saying, 'Oh, this is terrible,'" Bloomberg told the New York Times."New York City is not about wringing your hands; it's about doing something," he said. "I think that's what the public wants the mayor to do."



Exempt from the proposed ban are diet sodas that contain fewer than 25 calories per 8-ounce serving, fruit juices, dairy drinks and alcoholic beverages. The Times reports that restaurants, fast food chains and venues are affected because they are regulated by the city's health department, but vending machines, grocery or convenience stores and newsstands do not fall under the same regulation.


Fast-food chains would be required to hand out cups that are sized 16 ounces or less regardless of it someone purchases a diet drink, but refills would not be prohibited.


According to the New York City Department of Health and Mental Hygiene, 34 percent of adult New Yorkers are overweight and 22 percent are obese. One in five New York City kindergarten students are also obese.


Are New York City's health police going too far?


"There they go again," Stefan Friedman, spokesperson for the New York City Beverage Association said in an emailed statement, making reference to the Bloomberg administration's previous attempts at taking on sugary drinks . "The city is not going to address the obesity issue by attacking soda because soda is not driving the obesity rates. In fact, as obesity continues to rise, CDC data shows that calories from sugar-sweetened beverages are a small and declining part of the American diet. It's time for serious health professionals to move on and seek solutions that are going to actually curb obesity. These zealous proposals just distract from the hard work that needs to be done on this front."


Mayor Bloomberg previously supported a soda tax that was ultimately shot down by state lawmakers and in 2010, proposed to ban people from using food stamps to buy sugary drinks, sodas and teas. The USDA ultimately nixed that proposal in 2011, saying it would be too complicated to implement, HealthPop reported.


Dr. Marion Nestle, professor of nutrition, food studies, and public health at New York University, told HealthPop that she thinks the proposal is a creative way to curb some of New York City's obesity-driven health problems.


"Something needs to be done, and you can't just tell people to eat better and move more," Nestle said, emphasizing that this new proposal would simply change the default from a 20- to 30-ounce soda to one under 16 ounces. "If I'm given huge amounts of food, I'm going to eat it," she said. "Cheers for the Bloomberg administration, they're really trying to make environmental changes."


MoneyWatch: Companies blast proposed NYC sugary drinks ban


New Yorkers had mixed reactions to Bloomberg's latest attempt to take on sugary drinks.


"That's a good idea," Jillian Russel, a Brooklyn resident told CBS New York. "A lot of obese people are in New York."


"Who are you to tell us what we should or should not do?" another New Yorker said.


The proposal requires the approval of the city's Board of Health -- which is likely since all members were appointed by Bloomberg -- and could go into effect as early as March 2013. Bloomberg defended the proposal from "nanny state" critics, saying he's only limiting customer choices and they can always opt to buy more.


"Your argument, I guess, could be that it's a little less convenient to have to carry two 16-ounce drinks to your seat in the movie theater rather than one 32 ounce," Bloomberg told the Times sarcastically. "I don't think you can make the case that we're taking things away."


What do you think of the proposed ban?

Biggest Losers with Diabetes Shed Medications




Contestants in The Biggest Loser participate in the show because they want to lose a significant amount of weight and to compete for big prize money. But an additional benefit for participants who have prediabetes or diabetes has been their ability to shed their use of diabetes medications within weeks of starting the show's exercise program.


Could you be a big loser too?


"The Biggest Loser" was a topic of discussion during the recent annual meeting of the American Association of Clinical Endocrinologists in Philadelphia, where the show's medical advisor, Robert Huizenga, MD, explained the health improvements seen in contestants with prediabetes and diabetes. Those improvements were reported in 35 contestants who were the subject of a retrospective study.

The 17 men and 18 women had a mean weight of 315 pounds and a mean body mass index (BMI) of 46 at the start of the show. Before going on the show, the contestants averaged 5 to 6 hours of TV watching daily and exercised about 120 minutes per week.


Seventeen of the study participants had normal glucose tolerance, 12 had prediabetes, and six had diabetes. The authors followed the men and women for 24 weeks.


Once the contestants joined the show, their physical activity levels rose dramatically from 2 hours per week to 4 hours per day: 1 hour of intense aerobics, 1 hour of intense resistance training, and 2 hours of moderate aerobics.


Here's a rundown of what the authors observed:



  • Average weight loss for the 35 participants was 3.7% at week 1, 14.3% at week 5, and 31.9% at week 24

  • Within just 1 week, individuals with prediabetes and diabetes showed improvement in fasting glucose, fasting insulin, and adiponectin (a protein involved in regulating the metabolism of glucose)

  • By week 5, blood pressure had declined from 138/90 to 123/76 mmHg, and everyone was able to stop their blood pressure medication

  • Also by week 5, "all diagnostic criteria for prediabetes, diabetes, and hypertension were absent in each participant, despite discontinuation of all diabetes and hypertension medications," reported Huizenga

  • At 24 weeks (6 months), percentage of body fat had declined from 48% to 30%, and HbA1c had declined 0.53%


Biggest Loser Diet number 1 for diabetes
In January 2012, US News and World Report rated The Biggest Loser Diet and the DASH diet (Dietary Approaches to Stop Hypertension) tied for the position as number 1 diet for fighting and managing diabetes. These two diets won out over 23 other entries, although they had some tough competition from three that tied for second place: the Ornish Diet, the Mayo Clinic diet, and the vegan diet.


Cheryl Forberg, a registered dietitian and the nutritionist for "The Biggest Loser" for 12 seasons, also co-authored the diet for the show and counseled all of the show's contestants over the years. She noted that 25% of participants have diabetes when they report to The Ranch (where contestants participate in new eating habits and exercise programs), "but they all leave without it."


Huizenga noted that by the end of the program, contestants averaged 1 to 2 hours per day watching TV or using a computer. All the participants are told to exercise 90 minutes per day for the rest of their lives.


For "The Biggest Loser" contestants who start the show with prediabetes or diabetes, there's an opportunity to lose more than excess pounds--a chance to stop taking medications for diabetes and high blood pressure and a chance to have more control over their lives and their health. Can the biggest losers motivate you?

Science backs benefits of tart cherries for treating pain




Researchers are again touting the benefits of tart cherries that they say could help millions of pain sufferers with arthritis and other inflammatory joint conditions, without side effects of medications that often lead to complications and more prescriptions.


Tart cherries have the highest anti-inflammatory properties of any food


In findings presented by Oregon Health & Science University at the American College of Sports Medicine Conference (ACSM) in San Francisco, California, Scientists even went as far to say that tart cherries have the highest anti-inflammatory properties of any food.

Even the researchers are intrigued by the notion that food can control pain to the same degree as pharmaceutical medications, but without the side effects.


Previous research has suggested tart cherries inhibit enzymes in the body that are linked to pain in inflammation.


Kerry Kuehl, M.D, Dr.PH., M.S., Oregon Health & Science University, principal study investigator said in a press release, "I'm intrigued by the potential for a real food to offer such a powerful anti-inflammatory benefit – especially for active adults."


The study found just how good tart cherry is for controlling arthritis pain when researchers enrolled 20 women with osteoarthritis in a study, age 40 to 70.


The women drank tart cherry juice twice a day for three weeks. At the end of the study they reported a significant reduction in pain.


Drinking the juice, or eating cherries also has health benefits because the fruit is rich in antioxidants and can help you get a good night's sleep because they contain melatonin.


Osteoarthritis is common especially among athletes because it develops from wear and tear on the joints. Pain and inflammation associated with the condition is the result of cartilage breakdown.


Studies also show tart cherry juice could help athletes recover from pain after strenuous events. If you suffer from joint pain, check out this recovery routine from sports dietician Leslie Bonci, M.P.H., R.D. LDN, CSSD, called the “red recovery routine”. It’s possible to control pain and inflammation with a simple dietary intervention, which is good news for millions of pain sufferers who need to avoid medications that can interact with other prescriptions and cause side effects.

Curing diabetes via surgery, without weight loss









  • 640_surgery.jpg








Cristina Iaboni had the dubious distinction of being not quite obese enough. For all the pounds on her 5'5" frame, she did not meet the criteria for bariatric surgery to help control her type-2 diabetes.


Yet six years of medications and attempts at healthy living had failed to rein in her blood glucose, leaving Iaboni terrified that she was on course to have her kidneys fail "and my feet cut off" -- common consequences of uncontrolled diabetes.


Then the 45-year-old Connecticut wife, mother of two and head of human resources for a Fortune 500 company, lucked out. In 2009 she met with Dr Francisco Rubino of Weill Cornell Medical Center in New York. He had just received approval to study experimental surgery on diabetics with a relatively lean weight-to-height ratio, or body-mass index (BMI). Iaboni was among his first subjects.


Three years on, she has dropped 50 pounds to reach a healthy 145 and has normal blood pressure without medication. That isn't too surprising: Weight loss is the purpose of bariatric surgery and often reduces blood pressure. More remarkable, Iaboni no longer has diabetes.


She is not the first patient with diabetes, which can be triggered by obesity, to be cured by weight-loss surgery. But she is a rarity for having it with a BMI well below 35 and over. That's the level at which the American Diabetes Association says surgery "may be considered" and that Medicare and some private insurers cover. And Iaboni's diabetes disappeared months before she shed much weight.


Her experience has raised an intriguing possibility: that some forms of bariatric surgery treat diabetes not by making patients shed pounds. Instead, by rerouting part of the digestive system, they change what signals the gut sends to the brain and the brain sends to the liver, altering the underlying causes of diabetes.


If proven, bariatric surgery may help people with type-2 diabetes who are less obese, overweight or even of healthy weight. And it might be effective against the currently incurable type-1, or "juvenile," diabetes, too.


"Every textbook says that diabetes is chronic, irreversible, and progressive," said Rubino. "But we have thousands of patients who once had diabetes and now do not."


"INSUFFICIENT" EVIDENCE


Bariatric surgeons have long been prone to declaring victory against diabetes way too soon, before large-scale, long-term data proved their case. "The evidence for the success of bariatric surgery in patients with a BMI below 35 is not very strong," said Leonid Poretsky, director of the Friedman Diabetes Institute at Beth Israel Medical Center in New York City. "Most of the studies have been very small and not well controlled."


The American Diabetes Association rates the evidence that bariatric surgery can cure diabetes as "E," the lowest of four grades. It calls data on patients with a BMI below 35 "insufficient," and says the procedure cannot be recommended except as part of research.


The immediate risks of bariatric surgery are small -- a 0.3 percent chance of dying within 30 days of the procedure. But a small fraction of patients develop infections, leaking from the stomach into the abdominal cavity, or gallstones, and it can cause nutritional deficiencies: There is less intestine to absorb vitamins and minerals, raising the possibility of osteoporosis and anemia.


Despite these red flags, the surgical option is attracting intense interest because the quest to cure diabetes has become almost desperate. In type-1 diabetes, the pancreas does not produce enough insulin, a hormone that moves the glucose in food into cells. In type-2 diabetes, cells become resistant to insulin. In either case, glucose remains in the blood, damaging cells and blood vessels, sometimes severely enough to cause blindness, kidney failure, or gangrene requiring foot or limb amputations.


In 2010, 8.3 percent of adults worldwide had type-2 diabetes (11.3 percent did in the United States), resulting in direct medical costs of $376 billion ($116 billion in the United States). By 2030, the global incidence is projected to rise to 9.9 percent, partly because of the rising obesity rate, with costs reaching $490 billion.


The possibility that bariatric surgery could cure diabetes emerged about a decade ago. A long-term study of thousands of patients in Sweden reported in 2004 that both gastric bypass and banding improved diabetes in many subjects. A 2008 study of 55 obese patients found that 73 percent of those who underwent gastric banding saw their diabetes disappear after two years, compared to 13 percent undergoing standard medical treatment such as medication, diet and exercise.


In 2009, surgeons at the University of Minnesota analyzed 621 mostly small studies of bariatric surgery in obese, diabetic patients. Their conclusion, reported in the American Journal of Medicine: 78 percent no longer needed medication to control their blood sugar. They'd been cured. Lap banding had the worst results, worsening diabetes in some patients.


But most patients in these studies were obese, many morbidly so. (The average BMI was 48.) The improvement in glucose control could therefore be credited to the patients' weight loss, which averaged 85 pounds.


CLUES FROM THE PAST


Rubino had a hunch that something else was at work. As a research fellow in diabetes at Mount Sinai Hospital in New York in 1999, he was reviewing the medical literature one day for guidance on how to best perform bariatric surgery on a man with a BMI of 80. He found papers from the 1950s and earlier reporting that surgery for peptic ulcers had cured diabetes.


Ulcer surgery removes a portion of the stomach and reconstructs a connection to the intestine, much as gastric bypass does. Few diabetes experts had noticed the old papers; they were published in surgery journals, which endocrinologists seldom read.


His serendipitous find led Rubino to other papers describing operations on the digestive tract that cured diabetes, something that, according to medical textbooks, was unthinkable.


"Within two weeks of surgery and sometimes sooner, these patients were off their insulin, off their diabetes drugs, and with normal blood glucose levels," said Rubino. "That was too fast to explain by weight loss."


Yet that's how experts explained bariatric surgery's effect on diabetes, especially as the procedure took hold in the 1990s. Few surgeons focused on how quickly the condition disappeared, said Rubino, "or they speculated that patients weren't eating much after the surgery, and that's what cured their diabetes."


He began pursuing the idea that surgery might improve diabetes directly, rather than through weight loss. "I was ignorant of diabetes, so I wasn't burdened by too much knowledge," Rubino said. "Something that might have seemed heretical didn't seem impossible to me."


Rubino modified the popular gastric bypass surgery, called Roux-en-Y, to test his idea on diabetic lab rodents. In the classic operation, the stomach is pinched off so it can hold less food. Surgical cuts keep the rest of the stomach and the top of the small intestine, called the duodenum, from receiving any food. Instead, the stomach empties directly into the bottom of the small intestine, the jejunum. In Rubino's variation, called duodenal-jejunal bypass (DJB), the stomach is untouched, but the rest of the procedure is the same.


The rats that Rubino operated on beginning in 2000 were cured of diabetes much more quickly than their weight fell. It was the first rigorous evidence, from a well-controlled study, that gut surgery has an anti-diabetes effect.


In 2006, Rubino was ready to move from rats to people. Two patients, with BMIs of 29 and 30, underwent his procedure. Their blood sugar levels returned to normal within days, though they lost no weight. In his most recent trial, reported in March in the New England Journal of Medicine, Rubino and colleagues at Catholic University in Rome performed standard gastric bypass surgery or a procedure similar to DJB on people with type-2 diabetes. After two years, 15 of 20 bypass patients and 19 of 20 DJB patients no longer had diabetes.


Curiously, although patients shed pounds, there was no correlation between weight loss and blood glucose, the key marker of diabetes. "Bariatric surgery is more effective on diabetes than obesity," said Rubino. "Patients don't become lean, but they do not have diabetes anymore."


From gut to brain


Research from the University of Toronto, reported online this month in Nature Medicine, may finally explain why. It examined the effects of bypass surgery on rats with type-1 diabetes, which is considered even harder to treat than type-2. Normally the jejunum receives only digested mush, as nutrients have already been absorbed in the duodenum, explained lead researcher Tony Lam.


Bypassing the duodenum allows the jejunum to receive an influx of nutrients for the first time, said Lam. Sensing them, the jejunum sends a "got glucose!" signal to the brain. The brain interprets that as a sign of glucose overabundance and orders the liver to decrease glucose production. Result: The rats no longer have diabetes.


"I believe that similar mechanisms are taking place in surgery for type-2 diabetes," said Lam. "It strengthens the case for the surgery treating diabetes independent of weight loss."


His rat study shows why lap banding and stomach stapling are less effective against diabetes than gastric bypass. Banding causes diabetes to go into remission in about 50 percent of patients, probably due to weight loss, said endocrinologist Dr Allison Goldfine of the Joslin Diabetes Center in Boston.


In contrast, the diabetes-remission rate after Roux-en-Y is 80 to 85 percent. "The improvements in blood glucose with Roux-en-Y appear to occur very early, by day three after surgery, so patients are being discharged with no medication," she said. Something other than weight loss "must be going on."


Goldfine has launched a study of diabetics with BMIs of 30 to 42 to compare outcomes after lap band surgery, Roux-en-Y, and intense medical management.


A year ago, Rubino began the first large study for type-2 diabetes patients with a BMI as low as 26, where "overweight" begins. The cost of the bypass surgery is covered by a grant from Covidien Plc, which makes laparoscopic instruments and surgical staplers. He aims to enroll at least 50 patients, following them for five years; he has operated on 20 so far.

Diabulimia Dangerous Practice Among Type 1 Diabetes Patients




People with type 1 diabetes do not produce insulin, so they must take insulin injections to stay alive. Some type 1 diabetes patients, however, are engaging in a dangerous practice called diabulimia in which they restrict their insulin in an attempt to lose weight.


Diabulimia is not new


A quick review of the medical literature reveals few peer-reviewed articles on diabulimia, with one dated 2007 entitled "'Diabulimia' a growing problem among diabetic girls." But the scarcity of literature does not mean this practice is not dangerous nor uncommon.




Ads by Google




In fact, a study published in Diabetes Care in 2008 reported that out of 234 women with type 1 diabetes, 30% said they had restricted their insulin intake at some point in order to lose weight. An 11-year follow-up of these women showed that those who had restricted their insulin were more likely to experience diabetes complications and also had a shortened lifespan and increased risk of death.


Video and research on diabulimia
To help emphasize the dangers of diabulimia, the American College of Endocrinology has created a short video narrated by Kathryn Ackerman, MD, MPH, from Children's Hospital Boston. Ackerman not only explains what diabulimia is and the health dangers it can cause, but also talks with two people who have type 1 diabetes: a female fitness expert who was diagnosed with type 1 diabetes at age 14 and fought weight gain with exercise, and a woman who once suffered with and who subsequently overcame diabulimia.


Because type 1 diabetes often first appears close to or during adolescence, young girls, who are the ones more likely than males to engage in diabulimia, feel pressured to be thin. This pressure, along with the increased attention to food that is necessary to manage type 1 diabetes, are risk factors for diabulimia.


According to a 2011 article in the World Journal of Diabetes, individuals with type 1 diabetes are at high risk for eating disorders. The authors also noted that those who engage in diabulimia experience "more frequent episodes of ketoacidosis and an earlier than expected onset of diabetes-related microvascular complications, particularly retinopathy."


How to recognize diabulimia
In the video on diabulimia, possible signs of diabulimia were noted and include:



  • Elevated hemoglobin A1c levels

  • Unexplained weight loss or weight gain

  • Blood sugar records that do not match HbA1c results

  • Preoccupation with body image

  • Excessive thirst and/or urination

  • Depression and/or fatigue

  • High blood sugar levels

  • Bladder and yeast infections

  • Cancelled doctors' appointments

  • Discomfort eating or taking insulin in front of others


The best way for individuals with type 1 diabetes to resist the temptation to limit their insulin as a way to lose weight is to exercise and practice healthy eating habits. Having a support team, including family, friends, medical professionals, and diabetes support groups can help people with type 1 diabetes not fall into the dangerous habit of diabulimia.

Paper Chronicles 8-Year Salmonella Outbreak Tied to Chicks




Boots-on-the-ground epidemiology -- including interviews, disease surveillance, and traceback -- was key in helping health officials solve and control an 8 year salmonella outbreak, the longest in U.S. history, which was ultimately tied to mail order chicks.

Between 2004 and 2011, 316 reported illnesses from 43 states were linked to the same outbreak strain. A new paper published in the New England Journal of Medicine chronicles just how investigators were able to crack the case. Researchers say it is likely that thousands of additional infections occurred in association with the outbreak, but were not reported.

In April 2005, the Colorado Department of Public Health and Environment identified three Salmonella serotype Montevideo isolates with the same genetic patterns. After interviewing the patients, local health officials learned that all three had been exposed to chicks or ducklings bought at feed stores the week before they got sick.

Officials then checked PulseNet, the national network for foodborne disease surveillance, and found that the same rare outbreak strain had been isolated from five other people in four states: Kansas, New York, Oklahoma, and Texas.

By March 2006, health officials had zeroed in on New Mexico agricultural feed stores that sold young poultry during 2005.

"New Mexico was chosen because it had a large number of cases as well as resources available to support investigation activities," reported researchers in the NEJM paper. "Stores identified in an Internet search were randomly selected for an in-person or a telephone interview. The standardized questionnaire focused on the source of the live poultry, volume of live poultry sales, handling and hygienic conditions of poultry in the store, knowledge about the risk of transmission of Salmonella from poultry to humans, and education of customers about this risk."

Using information from patients, investigators were able to trace young poultry back to where it had been purchased at the retail level, and back to mail-order hatcheries.  chickies_iphone.jpg  

According to the paper, over the duration of the outbreak, cases peaked annually during the spring, but the greatest number of reported cases came in 2006. Those sickened ranged from age 1 to 86 years old with a median age of 4. Of those with information available, 143 (54 percent) were 5 years of age or younger and 149 patients (53 percent) were female.

Perhaps most concerning -- especially in light of the growing interest in raising backyard chickens across America -- is that most of the parents whose children were involved in the outbreak told investigators they did not know that Salmonella could be spread through contact with poultry.

"When interviewees were asked if they had known that Salmonella infection could be acquired from contact with poultry, 16 of 76 respondents (21%) said yes, and 5 respondents (7%) reported receiving an oral or written warning at the time of purchase on the risk of acquiring salmonella infection from live poultry," wrote researchers.

Once investigators pinned down live poultry as the likely culprit for the illnesses, they faced the difficult task of tracing the birds back to where they came from.

"In 2006, we surveyed representatives from 54 agricultural feed stores identified as selling chicks in New Mexico; half were surveyed in the store and half by telephone," read the paper. "The median number of chicks sold per store was 600 per year (range, 50 to 5500). Of the 54 respondents, 21 (39%) reported that chicks from different shipments were comingled at the store, 31 (57%) reported that the bird housing area was cleaned daily, 11 (20%) reported that it was disinfected between shipments and 19 (35%) reported that it was disinfected only at the end of the season. Artificially colored chicks were sold by 32 of the stores (59%)."

Between 2005 and 2011, investigators traced live poultry from 59 case patients to determine where the birds had originated. For 48 of these households (81 percent), the origin was what officials have dubbed "Hatchery C."

They also identified seven other mail-order hatcheries during the investigation.

"Hatchery C is known to drop-ship birds for other mail-order hatcheries," the researchers reported. Drop-shipping is what happens when a hatchery can't fill a customer order and sends the request to another facility, which then proceeds to send the birds to the customer under the first hatchery's name. The drop-shipping further complicated the traceback. As the researchers noted, "investigators were unable to determine whether implicated birds were drop-shipped from Hatchery C."

According to the paper, "Hatchery C" ships birds to all 50 states and raises 4 million birds each year. Researchers reported that in 2006, veterinary consultants and poultry experts started helping the company prevent and control salmonella. "Specific recommendations were provided for increased biosecurity, enhanced rodent control, feed decontamination, routine surveillance of the hatchery environment through microbiologic sampling at the premises, and the use of autogenous poultry vaccine."

In August 2006, the company started vaccinating all adult chickens, but illnesses continued to be connected with live poultry from the hatchery.

"It is likely that a temporary lapse in the hatchery's standard operating procedures in 2010 resulted in increased bacterial loads in the hatchery environment," read the paper. "Findings from epidemiologic and environmental investigations and the fact that Hatchery C has a closed breeding facility that does not introduce birds from outside flocks suggest that this outbreak strain persisted in the hatchery's environment throughout the 8-year investigation."

The paper's authors said the long-running outbreak showed that control interventions at mail-order hatcheries can play a role in reducing the transmission of Salmonella, but it also shows the difficulty in making that happen, especially considering the length of the outbreak.

"Between January 1 and April 30, 2012, only one human case of infection with the outbreak strain was reported to PulseNet," the paper noted. "The trend of decreasing numbers of cases reported after the interventions at the mail-order hatchery and the low number reported in the first 4 months of 2012 support the conclusion that the interventions are helping to reduce human infections."

The paper suggests that consumers looking to reduce their risks practice good hand hygiene and encourage this behavior for children and young children, and points to CDC recommendations.

"High-risk groups, including children younger than 5 years of age, elderly persons, and immunocompromised persons, should not handle or touch chicks, ducklings, or other live poultry. Live poultry should not be allowed inside a residence, in bathrooms, or in areas where food or drink is prepared, served, stored, or consumed. Any equipment or materials associated with raising or caring for live poultry should be cleaned outside the residence."

Researchers noted that there are no hygienic or biosecurity standards for hatcheries selling live birds to the public, but argue that they should be put in place: "We recommend that public health and animal health officials and industry partners develop guidelines to reduce Salmonella transmission."

Scientists release childhood cancer genome data that could key treatments





(CBS News) In a research milestone, the
Pediatric Cancer Genome Project released the entire genomes of 520 normal and cancerous tumor tissue samples in the hopes that the information could help researchers combat childhood cancers.


Life-saving cancer drugs for children stuck in federal legislative limbo
Seattle Children's Hospital's cancer unit shows they are "Stronger"


More than 10,000 children are diagnosed with a childhood cancer each year, according to the National Cancer Institute, and more than 1,500 kids will die. The causes of childhood cancers are largely unknown, but leukemias and cancers of the brain and central nervous system account for more than half of cases.


The newly released genomic data more than doubled the volume of high-coverage, whole genome data currently available from all human genome sources combined. The information is valuable not just to cancer researchers, but also to scientists studying almost any disease, the researchers said.



"This effort has generated more discoveries than we thought possible," Dr. James Downing, the scientific director of St. Jude Children's Research Hospital in Mephis, Tenn. who leads the project, said in a news release. "We want to make this information available to the broader scientific community so that, collectively, we can explore new treatment options for these children. By sharing the information even before we analyze it ourselves, we're hoping that other researchers can use this rich resource for insights into many other types of diseases in children and adults."


The Cancer Genome Project launched in early 2010 and will cost $65 million for its three-year span. St. Jude is covering $55 million of the cost, and it's one of the first major privately funded genome sequencing projects to share it's data as soon as it becomes available. Researchers hope to sequence 1,200 genomes by the project's end.


The 520 genome sequences are matched sets of normal and tumor tissue samples from 260 patients with pediatric cancer. Researchers at St. Jude's Children Hospital are analyzing the genomic sequences to determine the differences between each child's normal and cancerous cells to pinpoint the causes of more than a half-dozen of the most deadly childhood cancers, an effort which has already produced a number of key discoveries reported in top scientific journals. The latest data was published in the May 29 issue of Nature Genetics.


What's unique about this approach is the most genome sequencing initiatives focus only on specific genes, which make up a small portion of the genome. The researchers for the project sequenced all the DNA in each patient's tumor, providing a more complete picture of DNA changes underlying the development and progression of childhood cancers.


"This approach has been more valuable that anyone could have predicted," said Dr. Richard K. Wilson, director of The Genome Institute at Washington University School of Medicine in St. Louis. "We have identified unusual, 'cryptic' changes in many patients' cancer cells that we would not have found using other methods. We are pleased to be able to share this data with the research community in hopes that others can build upon our initial discoveries."


But cancer treatments created from this information will take more research, the authors said.


Downing told TIME, "We need to start by getting it out into the hands of everybody in the scientific field - not only those in cancer research - so they can use it both as reference and as a discovery tool, and find new things that we have yet to find."

New funding will benefit UCLA pediatric research in cancer, epilepsy, and autism




Los Angeles is home to Mattel Children’s Hospital, which provides state-of-the art care to children in Los Angeles and throughout the globe. It is also a world-renowned research facility for pediatric research. On May 30, the facility announced that it had received a generous donation of $348,000 from the Today's and Tomorrow's Children Fund (TTCF).


The funds are earmarked for research for projects currently underway by the UCLA Children’s Discovery and Innovation Institute (CDI): deadly pediatric brain tumors, pediatric epilepsy, and advanced genetic testing for the causes of autism and cancer in children.






“Not only does Mattel Children’s Hospital UCLA provide world-class patient care, but our faculty members are also in the CDI’s laboratories studying the causes of diseases that afflict our patients and searching for new treatments and cures,” noted Dr. Sherin Devaskar, professor of pediatrics, executive chair of the department of pediatrics, physician-in-chief at Mattel Children's Hospital UCLA. She added, “However because of limited federal research dollars, we must rely on additional avenues for funding. TTCF is an innovative way for the community to embrace the work of our pediatric subspecialty physician researchers and actively participate in the exciting process of advancing science.”


The funds were allocated to several investigators. The grand prize of $140,000 was presented to Dr. Tom Belle Davidson, assistant professor of pediatric hematology/oncology, for her work in studying a potential therapy for one of the deadliest types of pediatric brain tumors called high-grade gliomas which have few treatment options and an overall five-year survival rate of only 10-30%. The study is focused on a vaccine created from immune system cells, known as dendritic cells (DC), taken from the patient's blood and treated with broken-down cells isolated from his or her tumor tissue during surgery. These stimulated DCs will then be injected back into the patient as a vaccine in order to teach the host immune system to identify the malignant brain tumor cells as “foreign” to the body. Researchers hope the treatment will show improved outcomes with fewer toxic side effects than current standard therapies. In addition Dr. Davidson and her team will investigate the use of a topical compound cream on the vaccination site that stimulates the innate immune system and has been shown to display antiviral and antitumor activity.


Another beneficiary of the funding is Dr. Joyce Wu, associate professor of pediatric neurology. She received $118,000 to help advance her team’s research into pediatric epilepsy, including types of the diseases that do not respond to medication. The researchers have already discovered in children with epilepsy that ultra-fast brain electrical activity called high-frequency oscillations (HFO) are found throughout the brain and are a potential biological marker—or biomarker—to help assess, monitor and predict the condition. This finding has been seen without the use of invasive surgical implants inside patients’ heads for days to weeks as part of their epilepsy surgery evaluation and was correlated to surgical removal of seizure-causing zones resulting in seizure freedom.


In addition, the funds will allow Dr. Wu and her team to expand on the concept of HFO. Two goals include correlating the presence of HFO in children who are at high-risk of developing epilepsy later in life due to an inadequate oxygen supply at birth, a traumatic brain injury or tuberous sclerosis complex—formation of tumors in the brain or other vital organs. Additionally, with the ability to interpret HFO “live” in the operating room and immediately study affected brain tissue, this could potentially lead to a better understanding of the development of epilepsy and new antiepileptic drugs. The research holds promise for future clinical trials for better surgical brain mapping and potential disease-modifying therapy to prevent the development of epilepsy altogether, not merely stopping seizures with anticonvulsant medications.


An award of $90,000 was presented to Dr. Julian Martinez-Agosto, assistant professor of human genetics and pediatrics, for his research focused on the genetic risk factors of autism and cancer predisposition. Dr. Martinez-Agosto’s research focuses on genetic conditions in which children experience overgrowth: a situation in which their bodies grow faster than their peers. A subset of these children has autism. By using the latest technologies, they are able to identify the genetic changes in these children in order to expand their understanding of the causes of autism and, in some cases, a predisposition to cancer.


In addition, the funds will enable Dr. Martinez-Agosto and his team to use a new, efficient way to establish a personalized genetic-based diagnosis called “next generation whole exome sequencing” to identify mutations in pediatric patients with overgrowth syndromes. This technology will allow them to examine each letter in the patient’s genes, sequencing DNA to identify rare mutations that are predicted to cause autism, overgrowth, and/or cancer predisposition. The findings are expected to enhance the understanding of the genetic risk factors for autism and the biology of pediatric growth disorders, as well as provide new potential targets for therapies.

Finding solutions to an embarrassing female problem
















It is not an unnatural occurrence – 40 percent of postmenopausal women experience vaginal dryness and an undetermined number experience this condition following childbirth and breast cancer. These numbers remain a mystery, because so few women are willing to discuss this issue with a doctor and many surveys exclude the latter two groups.


Vaginal lubrication is linked to insufficient levels of estrogen, which tend to plummet during menopause, following pregnancy and with treatments for breast cancer. This condition, however, is something women should be discussing with their doctors. Vaginal dryness can be a result of more serious conditions, such as the autoimmune disease, Sjogren’s syndrome, or it could be caused by certain medications, like antidepressants. 


Regardless of the cause, intercourse can become very painful.  Women may lose the desire to have sex or endure unhealthy pain in the attempt to appease their partner. The impact on your sex life and health –mental and physical – is significant.


There are several things women, particularly menopausal women, can do to find relief from vaginal dryness naturally – and it comes down to simple things you already know are important to caring for your health. These are habits you should make a priority – vaginal dryness is a sign that something is awry inside your body.


1. Hormone balance


Hormonal shifts can occur throughout the female lifespan, but none are as great as the rapid, and often sudden, decline that accompanies menopause. During perimenopause progesterone begins to decline and some women may experience a relative increase in estrogen. When menopause hits, however, estrogen plummets as well. Among the responsibilities of estrogen is vaginal lubrication, which is why vaginal dryness is common in postmenopausal women.


Hormone therapy can bring relief – restoring estrogen and progesterone levels to normal levels can bring back the natural mechanism that supports vaginal lubrication. Studies have shown that in addition to treatment with the estradiol, the estrogen hormone, estriol, is also very effective.


2. Nutrition


Eat plenty of healthy fats. Fats are essential for making hormones - just make sure you choose the healthy ones, like mono- and polyunsaturated fats. Good sources of these fats include walnuts, almonds, olive oil, avocados and certain types of fish. Just remember, fats should consume no more than 20 percent of your diet.


3. Hydrate


Keep your body hydrated. Hydration keeps the body’s mucous membranes moist and functioning. Alternative beverages, like coffee, soda and alcohol, dehydrate the body further. Menopausal women or women approaching menopause, often have trouble ridding these toxic substances from their body, furthering the effects of dehydration throughout the body and exacerbating vaginal dryness.


4. Avoid irritants


Feminine sprays, douches and antibacterial and deodorant soaps steal moisture from the delicate tissues of the vagina and surrounding tissue. Choose soaps that can maintain the pH balance of the vaginal tissue. Look for a moisturizing, hypoallergenic soap with no dyes or fragrances that is non-alkaline and pH balanced.


5. Lubricate


There are many lubricants on the market today. Some have even been specially formulated for menopausal women. Just be sure to choose a water-based formula. There are also all-natural products you can use, like extra virgin coconut oil, which offers a pleasant odor in addition to adequate lubrication.  In some cases, you may simply need to learn to lubricate yourself – moisture can pool in the back of the vagina, making it impossible to reach during sexual intercourse. In this instance, you can use your finger to pull the moisture down and coat the dry surfaces.

Gender bias found in fertility counseling for cancer survivors




Recent medical advances have increased the number of cancer survivors. Following successful treatment and return to a normal life, a number of cancer survivors in their reproductive years desire to start - or complete - their family. Unfortunately, however, the cancer treatment can impact their therapy.


A new study by Swedish researchers has found that more men than women are counseled regarding fertility preservation before embarking on a treatment regimen. Researchers at the Karolinska University Hospital (Stockholm, Sweden) and the Uppsala University (Uppsala, Sweden) published their findings online in the Journal of Clinical Oncology.






The goal of the study was to investigate the perception of fertility-related information and use of fertility preservation in male and female cancer survivors who were of reproductive age. The authors reviewed data from population-based registers in Sweden and identified cancer survivors diagnosed from 2003 to 2007. Included in the study were cancer survivors who were age 18 to 45 years at diagnosis and had lymphoma, acute leukemia, testicular cancer, ovarian cancer, or female breast cancer that was treated with chemotherapy. A questionnaire was mailed to 810 eligible participants; 484 cancer survivors (60%) returned the questionnaire.


The researchers found that the majority of male participants reported having received information about the impact of cancer treatment on fertility (80%) and fertility preservation (68%); more than half of the men banked frozen sperm (54%). The women were less informed. Less than half (48%) reported that they received information about treatment impact on fertility and 14% reported that they received information about fertility preservation. Only seven women (2%) underwent fertility preservation. Predictors for receiving information about treatment impact on fertility were a pretreatment desire to have children, male gender, and being age 35 years or less at diagnosis. Predictors for receiving information about fertility preservation included male gender, age 35 years or less at diagnosis, and having no children at diagnosis.


The authors concluded that a marked gender difference was found in regard to the receipt of fertility-related information and use of fertility preservation. They stressed that an urgent need existed for the dissemination of fertility-related information to female cancer victims. This would allow them to participate in informed decisions regarding their treatment and future reproductive ability.

What Studies Support Vitamin D Belly Fat Diet, Discussed on Dr. Oz Show




Dr. Oz’s special guest, Dr. Keri Peterson, is the author of a book titled “The Vitamin D Diet: the revolutionary plan that melts stubborn fat fast.” She is a medical contributor and columnist at Women’s Health magazine and claims that following her Vitamin D Diet plan can result in the loss of 15 pounds of belly fat in 5 weeks.


“What we now know from new studies is that Vitamin D causes fat cells to become more metabolically active, which helps you burn more calories,” says Dr. Peterson. “And we’ve also learned that this is fantastic for people who carry their weight around their middle—that it helps you burn it there more easily. So, in our new book what we do is discuss new ways to incorporate Vitamin D rich foods into your diet.”






She discusses how that her Vitamin D Diet is a metabolism booster that shifts an individual’s body from a fat-storing mode into a fat-burning mode. “You lose the most weight in the first week and then you transition into a 4-week period where you can lose up to 15 pounds,” she states.


Dr. Peterson also explains briefly that she believes that one of the ways Vitamin D works on melting away belly fat is that Vitamin D not only increases fat cell metabolism, but also acts as an appetite suppressant. The appetite suppressing abilities of Vitamin D is attributed to stimulating the release of the hormone Leptin, which signals the brain telling you that you are full.


However, Dr. Peterson also tells viewers that the Vitamin D Diet is a portion control based program that limits an individual to 1400-1500 calories per day of Vitamin D rich foods that will provide the body with approximately 600 IU of Vitamin D daily.


The Vitamin D rich meals she recommends include food products that are Vitamin D fortified. Foods fortified with Vitamin D are necessary because very few foods contain vitamin D naturally. One example of a fortified meal is a breakfast that consists of three Vitamin D fortified eggs (of approximately 80 IU per egg) plus two slices of Vitamin D fortified toast for a total of about 300 IU for breakfast.


She also recommends salmon that not only provides Omega 3 fatty acids, but per serving also provides up to 1,000 IU of Vitamin D. A 5-oz. can of salmon made into a salad with 6 ounces of yogurt can give a person up to 855 IU of Vitamin D in one meal.


One surprising source of Vitamin D rich food included “Pick Mushrooms” that had been treated with UV light at the end of harvest. Look for packaging that says “High Vitamin D” on the labeling she recommends. Three ounces of UV treated mushrooms can provide 400 IU of Vitamin D.


However, if you have a day when you just cannot get to Vitamin D rich-foods she says that supplements dosed at 600-1000 IU per day is fine as well. Dr. Oz added that 10-15 minutes of exposure to sunlight without sunscreen will also provide you with his recommended daily dose of Vitamin D.


While Vitamin D has been well studied and continues to be a topic of heated debate over how much Vitamin D is helpful and how much is harmful, research has shown that it is beneficial toward:


• Promoting absorption of calcium and bone health
• Boosting immune function
• Reducing inflammation
• Healthy neuro-muscular function
• Protecting against some forms of cancer


But what about the Vitamin D Diet plan claims that it melts away belly fat? What research shows that the Vitamin D Diet can live up to its promise of weight loss in the abdominal regions?


As it turns out, an internet search of weight loss studies associating Vitamin D with loss of belly fat does appear—albeit in limited studies—in credible scientific journals.


The most recent article was published this year in the January 2012 issue of the American Journal of Clinical Nutrition in an article titled “Calcium and vitamin D supplementation is associated with decreased abdominal visceral adipose tissue in overweight and obese adults.”


In a 16-week clinical trial, 171 test subjects were randomly divided into two groups. One group was given a calcium (350 mg) and Vitamin D (100 IU) fortified orange juice beverage 3 times daily, while the second (control) group was given orange juice without the supplemental nutrients. Computed tomography of the visceral adipose tissue (belly fat) was measured before and after the 16-week study.


What the researchers found was that although the overall weight loss did not differ significantly between the two groups, what did differ was that the calcium and Vitamin D fortified orange juice drinking group lost significantly more belly fat than the plain orange juice drinking group. The conclusion reached by the scientists was that calcium and/or vitamin D supplementation contributes to a beneficial reduction of belly fat.


Until additional studies regarding Vitamin D’s role in melting away belly fat clearly demonstrates that Vitamin D is necessary, and an understanding of its mechanism of action is determined, claims of the diet’s efficacy remain questionable. However, the Vitamin D Diet plan as explained on The Dr. Oz Show does offer good and sensible weight loss advice that combines a reasonable daily calorie restriction with healthy food choices. With that in mind, what do you have to lose by trying it?—except maybe some belly fat that just won’t go away otherwise.

Why Too Much Vitamin D Can Be Harmful




Much of the news about vitamin D revolves around making sure people get enough of the sunshine vitamin and warning everyone about the health hazards of being vitamin D deficient. But it also turns out that taking too much vitamin D can be harmful, and a new study from Copenhagen explains why.


Too much vitamin D can be dangerous


There's no shortage of studies concerning the benefits of vitamin D and the health risks associated with having low or deficient levels of the nutrient in your blood stream. Low levels of vitamin D have been associated with a wide range of health problems, including depression, severe asthma in children, and Parkinson's disease.






Perhaps the most commonly recognized benefit of vitamin D is its role in making sure calcium reaches the bones to support and maintain bone health, while a vitamin D deficiency is associated with osteoporosis and higher risk of fractures. In fact, research also suggests that higher than normal levels of vitamin D are necessary to ensure the effectiveness of bisphosphonates, which are drugs taken to boost bone density.


On the other hand, some previous studies have suggested that taking high amounts of vitamin D may be harmful. This new large study from the University of Copenhagen highlights the dangers of taking too much vitamin D.


How much vitamin D is too much?
The study involved an evaluation of 247,574 blood samples from the Copenhagen General Practitioners Laboratory, part of Denmark's civil registration system. When the investigators correlated vitamin D levels with mortality, they discovered the following:



  • The vitamin D level associated with the lowest death rate was 50 nanomoles per liter (nmol/L)

  • The death rate among people who had a vitamin D level of less than 10 nmol/L was 2.31 times higher than among individuals with a vitamin D level of 50 nmol/L

  • The death rate among individuals with a vitamin D level of more than 140 nmol/L was 1.42 higher than those at the 50 nmol/L level


At this point, scientists cannot explain why high levels of vitamin D are associated with a greater death rate. One of the study's authors, Darshana Durup, a PhD student, explained that "We hope that our study will inspire others to study the cause of high mortality with a high level of vitamin D."


Previous studies of vitamin D
The findings of several previous studies have indicated that high levels of vitamin D may be harmful. A recent Johns Hopkins study, for example, indicated that high vitamin D levels were associated with blood vessel inflammation, which is a risk for heart disease.


An Archives of Dermatology study reported that high normal levels of vitamin D have been associated with an increased risk of nonmelanoma skin cancer.


One study, however, suggested that a single megadose of vitamin D could be beneficial for women who experience severe menstrual cramps. In that study, one 300,000 IU dose five days before women began their menstrual cycle was effective in reducing the severity of menstrual cramping.


It appears clear there is a great need for more research into the risks and benefits of various levels of vitamin D. As for the current study, which is the largest one of its kind, the findings suggest too much vitamin D is associated with a higher risk of death.

Overweight women experience obesity stigma even after weight loss, study finds









  • obese _skinny_women.JPG








Overweight women face a multitude of hardships – such as discrimination in the workplace – that arise from the stigma surrounding obesity.  While weight loss may seem like the solution for women hoping to escape anti-fat prejudice, it may not be that simple after all.


New research out of the University of Hawaii at Mānoa, The University of Manchester and Monash University, has revealed that anti-fat prejudice still persisted against former obese women, even after they had lost a significant amount of weight.


“Previous research has shown that the harmful nature of obesity stigma crossed many domains,” Dr. Janet Latner, the study’s lead author at the University of Hawaii at Mānoa, told FoxNews.com.  “So we designed an experiment to look at whether obesity sting persisted once the weight had been dropped.”


Published in the journal Obesity, the study asked young men and women participants to read various stories about a woman who had lost about 70 pounds, or a woman who was currently obese or thin who had remained stable. The participants were then asked to rate the women’s attractiveness and then give their opinions on fat people in general.


“We were surprised to find that currently thin women were viewed more differently depending on their weight history,” Latner said in a press release.  “We found that people who had lost weight were viewed more negatively in terms of attractiveness than people who had remained stable” – regardless of whether or not they had remained thin or obese, Latner told FoxNews.com.


Negative attitudes toward the obese targets also seemed to increase when the participants were falsely told that the person’s weight was easily controllable.  


Though the researchers cannot explain exactly why the findings were the way they were, Latner and her colleagues theorized that people are perhaps more judgmental towards the obese, because they believe that it is something the person can easily manage.


“There are several theories as to why anti-fat stigma persists,” Latner said.  “The leading theory is controllability theory – suggesting that stigmatized conditions are despised more when they are perceived as easily controllable, a widespread perception about obesity.  Our findings partly supported this theory by demonstrating that reading vignettes describing weight loss led to greater obesity stigma than reading vignettes describing weight stability.”


Because of their staggering findings, Latner and her team agree that government intervention is necessary to reduce the prejudice against the overweight and obese.


“We really need public policies that combat obesity stigma,” said Latner.  “Findings on effective interventions to reduce weight stigma are limited.  Some evidence suggests that social consensus approaches, cognitive dissonance approaches and intensive education approaches can be effective in reducing stigma.”


According to Latner, while obesity is important to combat in today’s society, obesity stigma is just as important to address, because its persistence could deter overweight women from shedding the pounds.


“The strength of obesity stigma is so powerful, pervasive and persistent,” Latner added.  “[Our results show] just how strong and harmful it can be. Many people are seeking weight loss to shake off the sting of obesity, and they may not necessarily achieve that.”

Food for Thought: Q&A with Tony Corbo






Tony Corbo is the senior lobbyist for the food campaign at Food & Water Watch. He is responsible for food-related legislative and regulatory issues that come before Congress and the Executive Branch. Tony has extensive organizing experience, having directed major public employee representation campaigns in several states. He has also directed political campaigns at various levels, and he served as the administrative assistant to a member of Congress. He holds a Bachelor of Arts degree in Public Affairs from The George Washington University and a Master's degree in Industrial and Labor Relations from Cornell University. 






Olivia Marler interviewed Tony for a series of conversations with food safety leaders that she calls "Food for Thought."






How did you get into food safety?





tony-corbo-350.jpg

We are all consumers, so food safety should be on everyone's radar screen.  My interest in food safety as a public policy began when I was a union representative for the American Federation of State, County, and Municipal Employees in the 1970s and 1980s and I came into contact with state and local food inspectors.  I developed a strong appreciation for what they do to protect the public -- especially during tough budget times.






For eight years I lived in California's Central Valley, where agriculture is the economic engine for that region. I eventually went to work for Congressman Gary Condit, who represented the Fresno, Stanislaus, Madera and Merced Counties in California.  I had to deal with agriculture and food policy on a daily basis.






In 2000, I was interested in a campaign that the public interest advocacy group Public Citizen had started to preserve the labeling requirements for irradiated foods, so I went to work as a staffer there. We fast realized that food irradiation was part of a bigger problem with the way our food was being produced, so we expanded our efforts to work on food safety in a broader context.  In 2005, Food & Water Watch was born and those of us who worked on food and agriculture public policy at Public Citizen continued our food safety work here.






What is the most immediate change that could be made to improve food safety by industry? And by the government?






It is in industry's best interests to have effective food safety measures in place.  I believe that most food producers and processors realize that.  A foodborne illness outbreak caused by sloppy production practices could put any company out of business in a heartbeat.






On the meat and poultry side, I think that industry needs to realize that it has to drop its opposition to having enforceable performance standards to deal with such pathogens as Salmonella. While progress has been made to reduce the levels of Salmonella in poultry and meat products over the past 10 years, the progress has stalled in recent years.






We have had major foodborne illness outbreaks and major recalls tied to Salmonella in meat and poultry products.  We need a stronger preventative approach to dealing with that pathogen, so we would urge industry to work with key food safety advocates in the Congress, such as Senator Kirsten Gillibrand (D-NY) and Congresswoman Rosa DeLauro (D-CT), who have worked on legislation to give USDA additional authorities.






For those foods regulated by the Food and Drug Administration, I think that the industry along with everyone else is waiting for the proposed regulations called for by the FDA Food Safety Modernization Act to be released by the White House Office of Management and Budget  so that the public comment period can begin.






I have noticed that some industry groups and state agricultural extension programs are not waiting for the new regulations to be promulgated and have gone ahead with food safety training conferences so that producers and processors become familiar with how to develop effective food safety plans and how to monitor them to ensure that there is food safety process control.  Those efforts are commendable, but we really need to get those regulations out so that everyone understands what the food safety playing field looks like and what will be expected of industry by the FDA.


 


Antibiotic resistance arising from antibiotics in feed is a hot topic in food safety circles.  What, if anything, do you think should be done to regulate animal antibiotics? Should it be industry or government regulated?






Food & Water Watch agrees that there is overuse and abuse of antibiotics in animal production in the United States.  We have seen increasing numbers of foodborne illness outbreaks and recalls of products that have been contaminated with strains of pathogens that were antibiotic resistant.  That has led to illnesses caused by these pathogens to be prolonged because doctors were prescribing medicines that proved to be ineffective.






Food & Water Watch supports the enactment of the Preservation of Antibiotics for Medical Treatment Act (PAMPTA) that would restrict the use of antibiotics in animal production.  We believe that the approach taken thus far by the Food and Drug Administration has been much too timid, so we believe that legislation is required to deal with this issue.






Food & Water Watch has Factory Farm Map posted on its website that highlights the food safety issues associated with intensive animal production.  It can be accessed at
http://www.factoryfarmmap.org/






Food & Water Watch also supports the petition filed by the Center for Science in the Public Interest with the Food Safety and Inspection Service to declare certain antibiotic strains of Salmonella as adulterants so that a more preventative approach can be taken to deal with those pathogens found in meat and poultry products and keep them out of the food supply.


 


What do you think of the argument that smaller is safer, and that local, sustainable farms should be subject to different regulations than large, industrial farms?






I do not subscribe to the notion that small is necessarily safer.  However, I think that food safety regulations can be flexible enough to take into account the burdens faced by smaller producers.  Food production is becoming too concentrated in the U.S. with a few large corporations controlling a bigger share of the market.  Consumers are demanding access to local and fresher sources of food.  Food safety regulations should not be used to disadvantage smaller producers.






I think that a good example of where the concerns of smaller businesses were addressed effectively by government is the recently issued draft guidance from the Food Safety and Inspection Service on the validation of HACCP plans in the meat and poultry industries.  The initial guidance document met with severe opposition in 2010 when it is first proposed because smaller processors argued that it was going to be too costly for them to implement the validation procedures that the agency was proposing.  Without sacrificing food safety, FSIS has issued a new guidance document that gives smaller processors various options to validate their HACCP plans.  I think that food safety regulations and policies can be made scale-appropriate without sacrificing food safety.






Do you generally avoid eating specific foods because of the risk associated with eating them? If so, which foods?






I am not a consumer of raw milk, although I do eat cheeses made from raw milk that have been properly fermented.  I have always preferred beef products cooked either well-done or medium well.   I regularly use a meat thermometer at home.  I have FSIS refrigerator magnets posted at the office and at home that list the proper cooking temperatures for different types of foods.






I have never been a big seafood eater and I really don't like raw seafood.  While I have occasionally put sprouts in sandwiches and salads, I have tended to use less of them as there have been too many outbreaks associated with raw sprouts.  I am getting to that age where I will become part of a vulnerable population susceptible to foodborne illness, so I am becoming more careful of what I am eating.

Blueberries are Powerhouses for Workout Recovery




If you have an important competitive athletic event in your future, you may want to consider adding blueberries to your diet. While known for their positive effects on blood pressure and mental health, this fruit has also been found to improve the rate of muscle recovery in female athletes.


Steve Stannard PhD, of the Massey School of Sport and Exercise in New Zealand, and colleagues recruited 10 female athletes to use a Biodex machine to create exercise-induced muscle damage (EIMD) in the quadriceps of one leg. The women were given blueberry smoothies five and 10 hours prior to exercise, immediately after using the Biodex, and again 12 and 36 hours after EIMD. Blood samples were drawn to measure oxidative stress, antioxidant levels and inflammation at 12, 36 and 60 hours after exercise.






After several weeks had passed, the test was repeated on the same athletes, on the other leg, but the smoothie given during the same time intervals was non-blueberry, but with similar antioxidant levels.


Blueberries appeared to improve the rate of recovery in the women’s leg muscles in just 60 hours after exercise. Contracting and extracting strength of the quadriceps was also improved.


Blueberries are known for their high antioxidant content which neutralize oxidative damage that lead to tissue destruction. Anthocyanin, a flavonoid that gives the fruit its color, has been linked to many health benefits, including anti-cancer effects and neuroprotective benefits.


But the researchers here believe blueberries have unique health-promoting properties beyond just the antioxidant compounds. Both smoothies appeared to reduce oxidative stress as measured in the blood samples. The team believes that the nutritional components may be interacting with the body’s own antioxidant production, leading to improved rate of recovery.


In addition to antioxidants, blueberries are a valuable source of vitamins. In just one serving, a single cup, you can get 14 mg of vitamin C - almost 25 percent of your daily requirement.

Nutritional therapy may be key to stopping autism
















In the last two years, autism cases have increased by 23 percent, according to the Centers for Disease Control and Prevention. That means that one in every 88 children in the United States is on the spectrum.


While there are various treatment options available for children suffering from autism, Dr. Jacob Teitelbaum, director of The Annapolis Center for Effective CFS/Fibromyalgia Therapies in Annapolis, Maryland, recently conducted a study that revealed food and nutrient sensitivities play a significant role in the lives of autistic children.


“With the average American getting over 150 pounds of sugar each year, and there being almost 85,000 new chemicals that have been added to our environment, it has become very difficult for many people's immune systems to tell friend from foe,” Teitelbaum said.  “This has resulted in a marked increase in sensitivities, especially to common foods.”


The study, funded by the NAET research foundation, utilized what is known as the NAET treatment –a method that involves a desensitization technique that ultimately “teaches the immune system to get back in harmony with the environment,” Teitelbaum said.


“For an immune system that is overreacting…NAET is like pushing the ‘restore factory defaults’ button when a computer program has gone haywire,” Teitelbum added.


NAET is a holistic treatment that is used to eliminate allergies of all types. According to NAET’s website, the technique uses “a blend of selective energy balancing, testing and treatment procedures from acupuncture/acupressure, allopathy, chiropractic, nutritional, and kinesiological disciplines of medicine.”


“It is really very simple,” Teitelbaum said of NAET.  “The person holds the substance that they are sensitive to while the NAET practitioner presses on some acupressure points along the spine.”  


To test its effectiveness on autism, Teitelbaum and his colleagues examined 60 autistic children who were each split into one of two groups: 30 children were treated with the NAET treatment and the other 30 children were not. The treatments lasted for one year with 20 minute sessions, twice a week.


“The effects were dramatic,” Teitelbaum said. “After one year of simple treatments, the children showed an average 50 to 75 percent improvement."


Mostly notably, Teitelbaum said, 23 out of the 30 autistic children who were treated were back in regular school by the end of the treatment period, as opposed to none of the 30 children who had not received treatment.


“If I was a parent with a child with autism, my child would be getting treated now,” Teitelbaum said.

New book by UCLA physician focuses on healthy eating for kids




Many parents try to instill healthy eating habits in their children; however, they are often confronted with stiff opposition. On many occasions, the outspoken little rug rat will state "I don’t like that" without even a taste. Coming to these parents rescue is a new book by Natalie Digate Muth, MD, MPH, RD. The physician who also holds a master’s degree in public health and is a registered dietician notes that her new book “Eat Your Vegetables' and Other Mistakes Parents Make: Redefining How to Raise Healthy Eaters” (Healthy Learning, May 2012) will assist parents in raising healthy eaters without constant mealtime struggles.


In her book, Dr. Muth, a pediatric resident at Mattel Children's Hospital UCLA and mother of two, provides parents with a step-by-step plan to help children embrace fruits, vegetables and other healthful foods without battles, bribes and coercion. The strategies, tailored to a child's age and development level, are based on scientifically proven research and are accompanied by real-life anecdotes and expert advice. Dr. Muth explained, “As parents, we all struggle with how to get our children to actually want to eat a healthy, balanced diet. As a formerly obese child, a mother of a once-picky eater, and a pediatrician acutely aware of the epidemics of obesity and inactivity in our children, I am highly motivated to help children and parents work together––free of mealtime battles—to adopt healthy eating and activity habits.”






Dr. Muth notes that her book helps parents assure healthful nutrition for kids of all ages; furthermore, while some of the strategies might be surprising, they work. She noted that parents will not only learn what exactly constitutes a healthy eating plan at various ages and stages but also will discover tips and tricks to get kids to actually want to eat healthy. Among the topics:



  • Learning the (reverse) psychology of getting kids to eat healthy.

  • Why the “clean plate club” contributes to childhood and adult obesity.

  • How using food as a reward causes more long-term damage than short-term parental sanity.

  • How subtle marketing and packaging tactics are designed to sabotage healthy eating habits.

  • Learning effective strategies to get the young “couch potato” up and moving.

Blood sugar control might not protect kidneys from type 2 diabetes




If you’re diabetic and keeping your sugars well under control, your kidneys may still be at risk for damage. That’s the conclusion of researchers from Yale University who found in a study review that intensive blood sugar control with Type 2 diabetes may not improve patient outcomes.


Intensive blood sugar control may not be the best approach


The study, led by Steven G. Coca of Yale, included a review of seven randomized clinical trials that included 28,065 adult patients who were monitored for two to 15 years.






The study authors found that taking higher doses of medications to control glucose for people with type 2 diabetes did not definitely improve the risk of kidney failure or death from kidney disease.


But the finding doesn’t mean controlling blood sugar levels and keeping HgA1c levels in check should be ignored.


"After pooling the results from the follow-up data in the seven studies examined, our analysis shows that intensive glycemic control may improve some things about the kidney that we measure, but did not affect patients' outcomes," said Coca in a media release.


What the study may mean for patients is another approach for ensuring the kidneys are protected from the disease, such as blood pressure medication. Other ways to ensure your blood pressure stays lower is by limiting salt, engaging in regular physical activity and maintaining a healthy weight.


The National Kidney and Urologic Diseases Information Clearinghouse also recommends consuming a moderate protein diet; guided by a nutritionist.


Speak with your doctor about medications that can help and make sure your health care provider screens your kidneys regularly for diabetic nephropathy with a urine test that measures GFR or glomerular filtration rate. Check your urine regularly for the presence of protein, either at home or at the doctor's office. Protein in the urine can signal kidney damage.


Researchers have assumed intensive glucose management offers protection to the kidneys from damage caused by diabetes. The study review shows keeping blood sugars low may not be the best approach for protecting the kidneys from harm associated with type 2 diabetes.
