E. Coli Illnesses Traced To Recalled Packages Of Vegetable Mix

November 26, 2015: 12:00 AM EST
A packaged mixture of diced celery and onion has been recalled because an outbreak of E. coli-caused illness has been traced to it. Taylor Farms Pacific recalled the mix “out of an abundance of caution,” the FDA said in a statement. The mixture was used to make chicken salad, Thai-style salads, packaged dinners and wraps, and other foods sold by Costco, Target, Starbucks and other stores and restaurants. The illnesses of 19 people in seven states nationwide were traced to the vegetable mix. Costco posted signs in its stores and provided detailed purchase logs to the U.S. Centers for Disease Control and Prevention to help it track buyers and ingredient sources.

Chinese Paradox: Overweight, Yet Malnourished

November 24, 2015: 12:00 AM EST
A Chinese government foundation reports that 31.8 percent of the 3,885 elderly it surveyed were overweight and 11.4 percent were obese. However, the rate of malnutrition was still high among low-income households, the single and widowed, and those of advanced age. Nearly 13 percent suffered from anemia, the study by the China Development Research Foundation found. About 16 percent of elderly men in rural areas of six Chinese provinces suffered from malnutrition. As of the end of 2013, fifteen percent (202 million people) of China’s population were at least 60 years old.

Need To Relax? Try New Skullcap Tea

November 24, 2015: 12:00 AM EST
With stress levels rising in the U.S. – 80 percent of Americans report increased stress in their lives – it should be no surprise that beverages, particularly tea, that deliver relaxation are finding a market. A company known as Traditional Medicinals recently added Stress Ease Cinnamon tea to its line of relaxation teas, sold as supplements. The new tea is unique in the market, according to the company, because a main ingredient is skullcap, purportedly a gentle and effective herb for reducing tension. Traditional Medicinals uses organic, non-GMO, pharmacopoeial grade skullcap blended with cinnamon and licorice.

Dietary Supplements Are Popular, Safe, According to Dietary Supplement Makers

November 23, 2015: 12:00 AM EST
More than two-thirds of American adults say they take dietary supplements, and a large majority (84 percent) believe supplements are safe, according to a survey sponsored by the Council for Responsible Nutrition, a trade organization representing dietary supplement makers. Americans have the most confidence in the vitamins and minerals category. The survey found that between 2014 and 2015, overall usage of vitamins and minerals and “specialty supplements” remained flat. Usage of “herbals & botanicals” and “sports nutrition & weight management” supplements grew five percent.

Universities Awarded Federal Grants To Study Food Aid Programs

November 23, 2015: 12:00 AM EST
Two U.S. universities were each awarded $1 million by the USDA to create regional nutrition education “Centers of Excellence.” The money will be used by the University of Tennessee (Knoxville) and Utah State University to fund research into nutrition education and obesity prevention for disadvantaged children and families. The Knoxville Center will focus on reducing obesity by analyzing programs to identify facilitators, barriers, best practices, training and evaluation needs. Utah State will use its $1 million grant to compare the effectiveness of the Expanded Food and Nutrition Education Program (EFNEP) and Supplemental Nutrition Assistance Program (SNAP) programs on participants and non-participants of different ethnic and racial backgrounds in five states.

Regulate Safety, Not Efficacy, Of Dietary Supplements, Former FDA Official Says

November 20, 2015: 12:00 AM EST
A former FDA official says don’t worry about the efficacy of dietary supplements – at least for now. Pay attention instead to their safety. Dr. Joshua M. Sharfstein, now at Johns Hopkins University, argues that many dietary supplements – vitamins, minerals, herbal extracts, etc. – are spiked with pharmaceuticals, are poorly manufactured, or lack the stated ingredients. Unfortunately, there is gridlock in dealing with the problem at the national level because manufacturers oppose closer scrutiny of efficacy and federal laws handcuff the FDA, keeping it from effectively monitoring the thousands of products on the market. But Sharfstein says that manufacturers would probably support stronger safety controls if they were not tied to analysis of product claims.

Gastric Balloon May Be Answer To Weight Loss For The Desperate Obese

November 20, 2015: 12:00 AM EST
Swallowing a balloon-pill may prove to be an effective weight loss technique, according to a new study. The “procedureless” gastric balloon is ingested as a capsule – dubbed “Elipse” by manufacturer Allurion Technologies – that is then “inflated” with 550 ml of liquid. In the study, patients who kept the balloon in place for four months lost 37 percent of their excess weight. The device is not considered a permanent solution to weight loss, but it does have the potential to help people who are overweight or obese but are not candidates for bariatric surgery. After four months, a valve opens on its own, releasing the liquid that is then excreted naturally.

Inability To Absorb Enough Vitamin E Is A Key Problem For the Obese

November 20, 2015: 12:00 AM EST
Obese people are often afflicted with metabolic syndrome, an array of conditions that include excess abdominal fat, high blood pressure, low "good" cholesterol, and high levels of blood sugar and fats. People with metabolic syndrome have one thing in common: they tend to be deficient in vitamin E (alpha-tocopherol), which the body needs to fight oxidative stress that can lead to heart disease, diabetes, Alzheimer's disease and cancer. The key problem for obese people is that, while they need higher levels of vitamin E to fight oxidative stress, their obesity is preventing absorption of the vitamin. And, contrary to recent findings, dairy fat does not increase the bioavailability of vitamin E, at least in supplement form.

Junk Food May Be Harmful To Health, But It’s Not The Main Cause Of Obesity

November 20, 2015: 12:00 AM EST
Junk food in and of itself may be nutritionally bankrupt, even harmful to health, but it is not the leading cause of obesity, Cornell University scientists say in a new study. It’s more complicated than that. For example,overall diet and amount of physical activity are also key factors. The study reviewed a representative sample of about 5,000 adults in the United States. It found that consumption of soda, candy and fast food is not linked to body mass index (BMI) for 95 percent of the population. Those on the extreme ends of the BMI spectrum – the chronically underweight or morbidly obese – are the exceptions because they are more likely to eat junk food and less likely to eat fruits and vegetables. The simple point is that narrowly targeting junk food is ineffective and self-defeating because “it distracts from the real underlying causes of obesity."

Omega 3 Supplements Not An Effective Treatment For Major Depressive Disorder

November 20, 2015: 12:00 AM EST
A British review of data from 26 randomized clinical trials involving 1,458 participants found little evidence that omega-3 fatty acid supplements effectively treated major depressive disorder. Omega 3s, thought to be essential for good health, are naturally found in fatty fish and some nuts and seeds. People treated with omega 3 fatty acids reported lower symptom scores than people with a placebo pill, the effect was small. And important limitations undermined researcher confidence in the results. The researchers acknowledged that most of the studies were small and of low quality.

Neither App Nor Coaching Effective At Long-Term Weight Loss

November 20, 2015: 12:00 AM EST
Weight loss programs for young adults that employ smartphone apps – even with personalized coaching – are no more effective at helping shed pounds than instructional fliers, a U.S. study has found. It’s upsetting news, because 35 percent of Americans in the 18-35 age range are obese. The randomized study included 365 people. One group used a free Android app called CITY (Cell Phone Intervention for You), designed for the study by university scientists. On average, participants who used the app lost about two pounds after two years, about the same as a control group that received handouts about exercise and nutrition. A separate arm of the study worked with the app and a personal coach, with the same disappointing results.

Risk Of Death By Heart Disease, Stroke, Etc., Reduced By Coffee Drinking

November 18, 2015: 12:00 AM EST
A large, 30-year study conducted among healthcare professionals found that coffee drinking was linked to a lower risk of death from heart disease, stroke, diabetes, neurological diseases and suicide. No association with reduced cancer risk was found, however. The risk of death was reduced by six percent among nonsmokers who drank at least one cup of coffee – either caffeinated or decaffeinated – a day. The greatest reduction in risk – 15 percent – was found among nonsmokers who drank between three and five cups a day. Controlling for age, alcohol consumption, BMI and other health and diet factors did not change the results.

Diet Rich In Soluble Fiber Reduces Risk Of Damaging Inflammation, Obesity

November 13, 2015: 12:00 AM EST
New U.S. research in mice suggests that intestinal inflammation caused by a microbiome that lacks soluble fiber may be a key factor in obesity and in obesity-related diseases like diabetes. The researchers found that adding more soluble fiber to the diet restores the gut microbiome and intestinal health. For the study, researchers tested the effects of various diets (i.e., soluble and insoluble fiber, protein and fat) on the intestinal tracts of mice. Among other things, the researchers found that improvements in gut structure from a soluble fiber-rich diet were due to changes in the gut microbiota that produced anti-inflammatory molecules (short chain fatty acids) used as fuel by intestinal cells.

More Fiber In Diet Is Good, Except When The Bacteria Control System Is Defective

November 13, 2015: 12:00 AM EST
Some studies have linked metabolic syndrome with the fermentation activities of bacteria on soluble fiber in the intestines. The bacteria digest the fiber, creating short chain fatty acids that control inflammation and reduce the risk of obesity. So it is usually healthful to increase fiber consumption. But a new U.S. study found a link between unchecked bacterial fermentation, increased short-chain fatty acids and increased liver lipids in people (and mice) with a compromised “TLR5” function. A defect in the TLR5 receptor reduces control of bacteria volumes. Bacteria multiply, lipids rise, as does the risk of non-alcoholic fatty liver disease and liver damage.

Count Your Bites, Then Count Your (Weight Loss) Blessings

November 13, 2015: 12:00 AM EST
A small U.S. pilot study has determined that weight loss could be as simple a matter as counting – but not steps, or minutes of exercise, or calories. The 41 participants who completed the study counting bites as they ate lost about four pounds on average (a healthful pound per week). Participants also committed to taking 20 to 30 percent fewer bites over four weeks. They changed nothing else about their eating or exercising patterns. Those who didn’t finish the program blamed the difficulty of keeping count, so computer scientists developed an algorithm for that. The technology was licensed to a local Utah startup (SmartBites) that is working on an app for wearable devices such as Android Wear and WatchOS devices.

Soy Protein Helps Expectant Mothers Control Blood Sugar Levels

November 11, 2015: 12:00 AM EST
A small Iranian clinical study finds that expectant mothers with gestational diabetes –high blood sugar levels – might benefit from soy protein in their diet. Soy has been shown to help people with type 2 diabetes, so it’s not a big stretch to expect it would also help pregnant women. High blood sugar during pregnancy can lead to hypertension, heavier babies, and a greater risk of needing a C-section. For the study, participants were divided into two groups, one of which stuck to a diet in which 35 percent of their protein was soy-based. After six weeks, blood sugar and insulin levels had dropped in the soy group, but rose for women in the control group, who had eaten protein from normal plant and animal sources.

New Vitamin Biscuits Deliver Nutrients Without Nausea To Expectant Moms

November 11, 2015: 12:00 AM EST
The need to enhance one’s nutritional intake before, during, and after pregnancy, without having to take big, nausea-inducing vitamin pills, led an entrepreneur and her friend to develop ERZO vitamin biscuits. The biscuits offer a more palatable and convenient daily solution for expectant moms. The vitamin-fortified, whole grain cereal biscuits are a good source of fiber, and provide nutritional values similar to prenatal pills and gummies. They avoid common problems such as nausea, reflux and food aversions. And they dovetail neatly with a major food trend: the rise in popularity of breakfast biscuits.

FDA Recommends Limits On Daily “Added Sugar” Intake

November 9, 2015: 12:00 AM EST
The FDA has issued a recommendation that Americans limit "added sugar" consumption to no more than ten percent of daily calories. The agency also wants food labels to distinguish between natural sugar and added sugar. Except for children three and under, that would mean a limit of 12.5 teaspoons, or 50 grams, of added sugar a day, about the same amount as in a can of Coca-Cola. The problem for American consumers is that sugar, honey and high-fructose corn syrup are not only found in obvious things like sodas, cookies and candy. They are also in healthful foods like low-fat yogurt, granola, wholegrain breads, ketchup, pasta sauce, canned fruit, prepared soups, salad dressings and marinades. Food industry skeptics argue that new labels distinguishing between natural and added sugar will only confuse shoppers.

Study Of Asthma Patients Finds No Benefit In Vitamin D Supplementation

November 5, 2015: 12:00 AM EST
Researchers have long wondered whether vitamin D deficiency led to other health problems for asthma sufferers. New U.S. research has determined that vitamin D supplementation does not reduce the severity or frequency of cold symptoms in patients with “mild-to-moderate asthma” any better than a placebo. The study involved 408 patients with insufficient or deficient levels of plasma vitamin D divided randomly into two groups, one of which received an initial 100,000 IU dose of vitamin D3, followed by 28 days of a 4,000 IU daily dose.

Energy Drinks Are A – Potentially Harmful – “Guy” Thing

November 4, 2015: 12:00 AM EST
The main consumers of energy drinks are men, suggesting a connection between “masculinity ideology” and energy drink use, according to a U.S. study. Drinking energy beverages may be a way of “performing masculinity... a way to raise masculine capital." The researchers analyzed data from 467 adult males who were asked if they agreed with statements that suggested traditional masculine attitudes. They also asked what participants expected from energy drinks and whether they felt that the drinks affected sleep patterns. Young white men especially associated the drinks with participation in extreme sports or leading an active and competitive lifestyle. But the researchers warned that the high caffeine content of the drinks can have adverse health effects, especially when it comes to sleep.

Will Birch Water Find A Market In The U.S.?

November 4, 2015: 12:00 AM EST
Coconut water has been flying high as a trendy thirst quencher for quite a while now, But it might get knocked from its lofty perch by birch – water, that is. Birch water is nothing new. Scandinavians have been drinking it as a rejuvenating springtime tonic for centuries. Made from birch sap, the water in its natural form spoils quickly. But pasteurization now preserves it for up to a year, and some experts expect that fact to help it capture some attention in the U.S. The virtues of birch water, according to several purveyors? Hydration, improvement in athletic endurance and performance, reduced sugar intake, weight maintenance, and liver and kidney detox.

Adding Pumpkin Flavor Doesn’t Make Doughnuts A Health Food

October 30, 2015: 12:00 AM EST
Pumpkin-flavored treats and foods containing pumpkin – pies, breads, etc. – pop up frequently at this time of the year. Pumpkin has some healthful properties but not everything flavored with pumpkin is good for you, except in moderation. Pumpkin itself is rich in fiber and low in cholesterol It also contains vitamin A, phytosterols, magnesium, manganese, copper, phosphorus, protein, zinc and iron. But pumpkin snacks and desserts, not to mention the lattes and coffees, offer none of the benefits of pumpkins, and may contain a lot of salt, fat and sugar.

Calcium Supplements Increase Risk Of Kidney Stone Formation

October 30, 2015: 12:00 AM EST
After reviewing urine collections and CT scans of 1,486 kidney stone patients, U.S.  researchers concluded that calcium supplements – but not foods rich in calcium – increase the risk of a recurrence of stones. Patients who took calcium supplements had lower levels of the components of kidney stones in their urine. However, they also had a faster rate of kidney stone growth. Vitamin D supplements, however, may help prevent stone formation.

Lack Of Movement – Not Just Sitting – Is Unhealthy Behavior

October 30, 2015: 12:00 AM EST
British researchers say that, contrary to other recent studies, sitting for long periods of time does not lead to an early death. The study monitored 5,000 people for 16 years, finding no association between sitting and an untimely death. The real problem is lack of movement, not sitting or standing per se. “Any stationary posture where energy expenditure is low may be detrimental to health,” the authors concluded. The results also cast doubt on the benefits of sit-stand workstations.

Fatty Diet Upsets Metabolism and Causes Anxiety, Depression

October 29, 2015: 12:00 AM EST
A diet of fatty foods can adversely affect more than the body, according to new French research in mice. Immoderate fat consumption can increase body weight and boost blood sugar leading to anxiety, depression and measurable brain changes. The study also showed that a fatty diet can thwart the beneficial effects of an antidepressant. The researchers noted that the metabolic impairments were reversed when the mice were taken off a high-fat diet, and their anxious symptoms decreased.

Red Wine Safely Improves Cholesterol Balance, Reduces Cardiovascular Risks

October 29, 2015: 12:00 AM EST
A two-year multinational study has determined that drinking a glass of wine each night could help people with type 2 diabetes better manage their cholesterol and cardiac health. Researchers said red wine was found to be not only safe, it was superior in improving overall metabolic profiles by modestly improving the lipid profile and increasing good (HDL) cholesterol and apolipoprotein A1 (a major constituent of HDL). It also decreased the ratio between total cholesterol and HDL cholesterol. Diabetics are more susceptible to developing cardiovascular diseases than the general population and have lower levels of "good" cholesterol.

Vitamin D/Calcium Supplements Do Not Prevent Regrowth Of Intestinal Polyps

October 29, 2015: 12:00 AM EST
Vitamin D and calcium supplements do not prevent the regrowth of colorectal polyps, the precursors of cancerous tumors, a large U.S. study has found. The random, controlled study was conducted at 11 hospitals and involved 2,200 adults aged 45-75 who took 1,000 IU of calcium and/or 1,200 mg of vitamin D each day, or a placebo. Each study participant had a history of colorectal polyps without any remaining polyps after colonoscopy. After 3-5 years, researchers found that daily supplementation did not reduce the risk of recurrent colorectal adenomas.

Increased Calcium Intake Offers No Bone Benefits For Older Adults

October 24, 2015: 12:00 AM EST
For many years, physicians have advised older patients to increase their intake of calcium, either through food sources or supplements, to strengthen bones and prevent fractures. But two studies by New Zealand researchers now confirm that the advice was worthless: boosting calcium intake neither improves bone health nor prevents broken bones. Increasing intake of calcium and vitamin D – recommended for older adults by some guidelines – provides no meaningful health benefit and may increase the risk of adverse outcomes linked to calcium supplements. A balanced diet provides enough calcium and vitamin D for most people, they said.

People With A Genetic Inclination To Type 2 Diabetes Have To Exercise More

October 24, 2015: 12:00 AM EST
Swedish researchers have determined that people with increased risk of type 2 diabetes – because of family history – have to exercise a lot harder to achieve the same results as others. A person with a mother, father, sister or brother who is a type 2 diabetic is three times more likely than others to acquire the disease. For the seven-month study, healthy but unfit and overweight men were divided into a high-risk and control group. Though the exercise routines were equally hard, the risk group attended more sessions and expended more energy. Both groups benefited: they all lost weight, reduced waist size and increased fitness. But the risk group had to exercise more to achieve the same results as the control group.

Avoid Toxic Bacteria This Fall: Refrigerate Those Caramel Apples

October 24, 2015: 12:00 AM EST
U.S. researchers have found that a dangerous bacterium known as Listeria monocytogenes increased 1,000-fold on a favorite fall treat: unrefrigerated caramel apples with sticks. By contrast, listerial growth was delayed on caramel apples without sticks stored at room temperature for three days. Refrigeration was the key difference, the scientists said. Caramel apples with sticks had no listerial growth for up to a week, and only a little growth over the next three weeks. Those without sticks had no listerial growth during four weeks of storage.

Milk Boosts Bioavailability Of Vitamin E In Obese People

October 23, 2015: 12:00 AM EST
A new U.S. study finds an association between vitamin E absorption and metabolic syndrome, the cluster of symptoms like obesity and high blood pressure that are a precursor of type 2 diabetes. The researchers at Ohio State University discovered that people with metabolic syndrome – 35 percent of Americans – do not absorb vitamin E. But that problem can be solved by adding cow’s milk to the diet. Study participants who drank milk along with the natural form of vitamin E – found in spinach, sunflower seeds, peanuts, etc. – absorbed between 26.1 and 29.5 percent of the vitamin. Participants with metabolic syndrome absorbed less vitamin E than healthy people. The bioavailability of vitamin E when taken with a glass of milk was nearly three times higher than expected.

Packaged Food Purchases Are On The Rise – An Unhealthful Trend

October 23, 2015: 12:00 AM EST
American consumers are buying more packaged foods, but the packaged foods they buy – especially at non-grocery sources – are less healthful than fresh foods purchased at supermarkets, according to a U.S. study. Packaged food purchases (PFPs) accounted for 78 percent of store-based food expenditures. Mass merchandisers, warehouse clubs and convenience stores are seeing an increase in food purchases. The top sources of calorie purchases are savory snacks, grain-based desserts, fruit drinks and juices, fresh plain milk, and regular soft drinks across all types of stores, including grocery stores. But these food and beverage groups are major sources of added sugars, saturated fat, and sodium.

Sit-Stand Desks May Be One Weapon In The Fight Against Obesity

October 23, 2015: 12:00 AM EST
U.S. researchers have shown that employees using a sit-stand desk burn as much as 87 calories more a day than peers who sit all day. It’s a small number of calories, but the researchers say it is significant enough to make a difference in the fight against obesity. Office workers sit more than 80 percent of the workday, increasing their risk of many sedentary-related problems, including cardiovascular disease, high blood pressure, and obesity. The cross-sectional study monitored employee activity over a five-day workweek. Participants – who had their sit-stand desks for an average of 1.8 years prior to the study – stood 60 minutes more each day than their sitting coworkers.

China: Many Barriers To Health Food Land Of Milk And Honey

October 20, 2015: 12:00 AM EST
Health food marketers may think of China as a sort of “promised land” of sales opportunities, if a Chinese food industry five-year plan is to be believed. By 2019, health food sales in the country are expected to reach $48 billion, for several reasons: a growing overall obesity rate (up 67 percent between 2002 and 2012), a doubling of the obesity rate for children and adolescents, severe vitamin and mineral deficiencies, and mounting high blood pressure and cancer rates. Though Chinese consumers want high-quality foreign health foods, it’s still a daunting procedure for multinationals to get their products to market. It can take two to three years, and up to $15,800, to get one health food product registered under China’s blue hat system. The new Food Safety Law, now in effective, adds other hurdles.

Millennials Not Content With Popping Nutritional Supplement Pills

October 20, 2015: 12:00 AM EST
Younger generations of Americans, particularly Millennials, are no longer content with knowing that their vitamin C tablet contains, well, vitamin C. They want to know more about the dietary supplements they take, and because they grew up in an age of information explosion, they know they can get that information somewhere, if not from the manufactuer. Where Boomers are content to know what’s in a supplement, Millennials want to know how the pill was made and where the ingredients were sourced. They want, in other words, transparency and traceability. Other important desirables: whole food ingredients (like nutritional greens), and functional foods and beverages delivered – not by pills – but alternatives like gummies, satchels, powders, etc.

Excess Fructose In The Intestines Linked To Bronchitis

October 16, 2015: 12:00 AM EST
A U.S. study reports that drinking beverages sweetened with high fructose corn syrup (HFCS) is associated with an increased prevalence and risk of chronic bronchitis in American adults. Adults who drink non-diet soda five or more times per week are 1.8 times as likely to develop chronic bronchitis as people who drink them only once or twice a month. And it doesn’t matter if smoking is involved. The researchers suggested that poorly absorbed excess fructose in the gut interacts with proteins to form antigens (“enFruAGEs”) that work their way to the lungs, triggering an immune response and causing bronchitis. More research is needed to prove the connection.

Wide Variety Of Breads Contain Carcinogenic Compound

October 14, 2015: 12:00 AM EST
The Environmental Working Group reports that 86 breads and baked goods it analyzed contained a possible carcinogenic ingredient known as potassium bromate. The compound, linked in animal studies to cancer and development of tumors, is added to flour to firm up the dough, help it rise and give the finished bread an appealing white color. California is the only U.S. state that regulates potassium bromate. It requires a warning label on food containing it. Among the 86 products containing the potentially harmful compound are Hormel Foods breakfast sandwiches, Weis Kaiser rolls and French toast, and Goya turnover pastry dough.

Diet Of Dried Plums Seems To Reduce Colon Cancer Risk

October 12, 2015: 12:00 AM EST
U.S. researchers have found that a diet rich in dried plums might ward off colon cancer by helping the gut retain beneficial bacteria. Earlier research has shown that disruptions to the microbiota spur the onset or recurrence of intestinal inflammation that can increase the risk of colon cancer. Dried plums, however, contain phenolic compounds that serve as antioxidants to neutralize the effect of free radicals that damage DNA. The new experiments in rats found that a dried plum diet increased the proportions of two major phyla of bacteria in the gut, while the control diet lowered the proportions. The tests also showed that rats eating dried plums had fewer aberrant “crypts” in gut wall tissue, a strong cancer indicator.

Promising – And Delivering – Gluten-Free Cereals Is No Easy Task

October 11, 2015: 12:00 AM EST
General Mills is betting heavily that gluten-free food products – a hot industry trend – will help revive its slumping cereal sales. So it’s no surprise that the company acted quickly when reports started coming in that some Cheerios buyers were experiencing intestinal discomfort, a symptom of celiac disease, an immune response to gluten. Oats, of course, do not contain gluten. But oats mills and cereal manufacturing plants can often be contaminated with wheat, rye or barley flour. General Mills spent tens of millions of dollars to make sure its huge Fridley, Minn., flour mill was itself gluten-free. But the fail-safe systems in place somehow failed. The company last week recalled 1.8 million boxes of Cheerios and Honey Nut Cheerios made at a plant in Lodi, Calif., after discovering the cereal accidentally contained wheat.

Wine Contains Lots More Arsenic Than Water, But Poses Small Health Threat

October 7, 2015: 12:00 AM EST
A U.S. researcher has determined that wine on average contains a lot more arsenic than the U.S. EPA allows in drinking water, but the risk of poisoning is small unless you’re also getting arsenic from other dietary sources, like apple juice, rice or cereal bars. The problem is especially worrisome for pregnant women, children and the elderly, the scientists said. They are more likely to consume large amounts of contaminated rice, organic brown rice syrup, seafood, wine, and apple juice. The study analyzed 65 wines from Washington, New York, California and Oregon. Washington wines had the highest arsenic concentrations, while Oregon's had the lowest. Arsenic leaches into water and soil – and then the food chain – when rocks containing the metalloid are eroded by rain, rivers or wind.

Science Has Abandoned Its Advice To Avoid All Whole Fats... Will The Feds?

October 6, 2015: 12:00 AM EST
Science has gradually reversed the conclusion first drawn by a scientist in the 1950s – namely, that America’s consumption of fat was the cause of the heart disease epidemic. Study after study over the last ten years has concluded that – contrary to the federal Dietary Guidelines for Americans – fat is not a cause of cardiovascular disease or obesity. And now a study shows that whole milk is not only not bad for you, it actually offers cardio-protective benefits. So, the question becomes, will the new federal dietary guidelines back off the warnings against consuming all fats? Will they suggest avoiding trans fats and encourage eating unsaturated fats found in fish, nuts and vegetable oils? One thing is sure, says one scientist: it is okay to have whole fat food, including whole fat milk, and that message “is slowly seeping into consciousness.”

U.S. Dietary Guidelines Not Based On Current Science, Journalist Says

October 6, 2015: 12:00 AM EST
The nutritional science on which the latest version of U.S. Dietary Guidelines is based may be outdated and misleading, according to a journalist writing in a scientific publication. Nina Teicholz argues that the guidelines, based on an expert report by a 14-member advisory committee, do not reflect recent scientific findings. For example, the committee said the association of saturated fats with heart disease is strong. But the panel did not review scientific literature on saturated fats from the past five years that had failed to confirm a link between sat-fats and heart disease. Teicholtz says that the committee’s analyses of nutritional study findings were less than rigorous, and may simply have relied on the outdated conclusions of industry-funded organizations like the American Heart Association and the American College of Cardiology. The article has prompted a congressional review of the expert report.

Simple Blood Test Could Speed Diagnosis Of Celiac Disease

October 5, 2015: 12:00 AM EST
To celiac diagnose celiac disease – a severe immune reaction to the protein gluten in wheat, barley, and rye – a physician has to take blood and intestinal tissue samples (gastroscopy), an uncomfortable, often painful procedure. Now Norwegian scientists have developed a simple test that may make it quicker and easier to diagnose the disease. The test is based on the fact that in celiac disease immune cells, known as T cells, analyze gluten molecules and decide that they are a harmful bacteria or virus. For the new test, a blood sample is taken, the blood is enriched with certain reagents, and gluten-reactive T cells are counted. People with celiac disease will have a much higher number of gluten-reactive T cells in their blood than non-celiacs.

Evidence Of Health Benefits Of Tea Is A Little Weak

October 5, 2015: 12:00 AM EST
A New York Times health columnist recently assessed studies that examined the benefits of coffee, finding that drinking coffee is indeed healthful. He then looked at studies regarding tea’s benefits, finding that most of the research has been conducted in Asia, and conclusions may not apply to Americans (who drink a lot less tea daily). Studies, for example, somewhat inconclusively linked tea drinking with less risk of hepatocellular carcinoma, liver steatosis, cirrhosis, chronic liver disease, depression, stroke, heart disease, cardiac death, cerebral infarction and intracerebral hemorrhage. The upshot is that Aaron Carroll is “a little less impressed with the body of evidence regarding tea.” He says the data are not enough to “strongly recommend” drinking tea, but there may be some potential benefits, and no harms.

Replacing Sat-Fats With The Right Foods Reduces Heart Disease Risk

October 3, 2015: 12:00 AM EST
Science for a long time has advocated removal of saturated fatty acids from the diet as a way to cut the risk of cardiovascular disease. But no one made any recommendations about what to replace those fats with. To find out what was best, U.S. scientists analyzed questionnaire data collected over at least thirty years from 84,628 women and 42,908 men free of diabetes, cardiovascular disease and cancer. They found that patients making lifestyle diet changes – specifically avoiding sat-fats – did best when they substituted unsaturated fats like vegetable oils, nuts, and seeds, as well as healthy carbohydrates such as whole grains. Those who turned to processed foods with low-quality carbohydrates from refined starches or sugars barely reduced the risk of heart disease.

To Reduce Risk Of Heart Disease, Increase Consumption Of Fruits, Veggies, Fiber

October 1, 2015: 12:00 AM EST
Short chain fatty acids (SCFAs) are known to reduce the risk of inflammatory disease, diabetes and cardiovascular disease. SCFAs are produced by bacteria in the gut by fermenting insoluble dietary plant fiber. Which foods best promote SCFA production? For this study, Italian researchers collected a week's worth of daily diet information from 153 adults. They were equally divided into omnivores, vegetarians, and vegans. After analyzing gut bacteria and metabolites from stool and urine samples, the researchers found that the highest levels of SCFAs were found in vegans, vegetarians, and those who regularly followed a Mediterranean diet. But no matter what dietary pattern was followed, high levels of SCFAs were strongly linked to regular consumption of fruit, vegetables, legumes, and fiber.

For Long-Term Weight Control, Avoid Starchy Vegetables

September 29, 2015: 12:00 AM EST
New data from a study by U.S. researchers show that some vegetables are not as good for dieters as others. Nutritionists have long advocated increased consumption of fruits and vegetables as a way to keep weight under control. The new study, however, finds that starchy vegetables, while certainly healthful, are less likely to help in weight loss and actually contributed to weight gain. Researchers analyzed data collected from national survey questionnaires submitted by 133,468 American adults over 24 years. Starchy vegetables like peas and corn were associated with long-term weight gain, while fruits and non-starchy vegetables were associated with weight loss.

Activating Nerve Cells In Fat Shrinks Fat Cells

September 24, 2015: 12:00 AM EST
The hormone leptin, which is produced by fat cells, tells the brain how much fat is available in the body. The hormone controls weight in the body by regulating food intake and metabolism. But no one knew how the brain signals the fat tissue to begin breaking down. Now Portuguese and U.S. scientists have determined in a mouse study that fat cells have their own nerve circuits, and these can be stimulated. They used a technique called optogenetics to locally activate the sympathetic neurons in fat. They saw fat cells break down and fat tissue shrink. The findings provide some hope that central leptin resistance – in which the brains of obese people do not react to leptin’s signals – can be treated.

Company’s Scientists Find That Its Weight Loss Program Works Well

September 22, 2015: 12:00 AM EST
A study conducted by scientists at weight loss company Medifast found the 4 & 2 & 1 Plan used at Medifast Weight Control Centers was effective for weight loss after 12 weeks. The scientists looked at the records of 310 customers, finding that the average weight loss was 24 pounds. The plan was also effective at preserving lean muscle mass and improving cardiometabolic risk factors. Customers – men, women, and younger and older adults – who stuck with the plan for 24 weeks lost an average of 35 pounds. More than 75 percent of active 12-week customers lost at least five percent body weight and more than 85 percent of 24-week customers lost five percent or more.

Older Men, But Not Women, Benefit From High Intensity Exercise

September 20, 2015: 12:00 AM EST
Danish researchers report that high-intensity training (HIT) benefits older males but not older females. They monitored men and women age 62 and older who participated in an exercise regimen three times a week to see if their maximum muscle oxygen consumption (VO2max) would increase along with their mitochondrial oxidative phosphorylation (OXPHOS) capacity. Each session included five one-minute bursts of HIT activity. The men increased their VO2max and OXPHOS in the muscle and reduced their body fat percentage after six weeks. But no changes were observed in females. The researchers said more study is needed to determine why there was such a big difference in outcomes between the sexes.
