Pediatricians Caution Against Consumption Of Raw Milk By Babies, Pregnant Women

December 16, 2013: 12:00 AM EST
Expectant mothers, babies and young children should not consume unpasteurized (raw) milk or milk products – which can be legally purchased in 30 U.S. states – and should only consume pasteurized products, the American Academy of Pediatrics advises. Raw milk and milk products are a continuing source of bacterial infections that are especially dangerous to pregnant women, fetuses, the elderly, young children and people with compromised immune systems, the organization says. Raw milk and raw-milk products, such as soft cheeses, have become increasingly popular, because of unfounded claims of health benefits. From 1998 through 2009, there were 93 recorded outbreaks of disease resulting from consumption of raw milk or raw-milk products, causing 1,837 illnesses, 195 hospitalizations and two deaths.

Multivitamins “Should Be Avoided”, Studies Say

December 16, 2013: 12:00 AM EST
Two new clinical trials testing the health impact of dietary and other supplements found that most, including multivitamins, not only are useless at preventing chronic disease or death, some increase the risk of death among generally well-nourished populations. In an editorial accompanying the studies, clinicians and public health experts said the use of supplements is “not justified, and they should be avoided”. Vitamin industry representatives countered by saying a study reported last year on 15,000 men found that multivitamins reduced cancer risk. Worldwide vitamin industry sales in 2012 were $23.4 billion, up three percent from 2011. Forty percent of Americans say they took multivitamins or minerals between 2003 and 2006.

A Healthy Diet Does Cost More, But Is Offset By Much Lower Healthcare Costs

December 15, 2013: 12:00 AM EST
Harvard scientists have figured out that it really is more expensive to eat healthy, but not that much more – only $1.50 a day, or $550 a year. In a meta-analysis of 27 studies across 10 affluent countries that compared the costs of eating healthy versus less-healthy meals, the researchers found that healthier diet patterns – for example, diets rich in fruits, vegetables, fish, and nuts – cost significantly more than unhealthy diets (i.e., those rich in processed foods, meats, and refined grains). The researchers said the price difference is very small in comparison to the economic costs of diet-related chronic diseases, “which would be dramatically reduced by healthy diets”.

China’s Commitment To GM Crops Is Challenged On Food Safety And Patriotic Grounds

December 14, 2013: 12:00 AM EST
Growing public sentiment in China opposing genetically modified crops – often seen not only as a scary food safety issue but as a strategy by the U.S. to weaken China and control the world’s food supply – has created a predicament for China’s government. The Chinese food ministry -- and its agri-science community -- has long been committed to the use of genetically modified crops, and to the development of its own GM varieties. To that end, it has spent a lot of research money on GM technology, hoping to ensure self-sufficiency in food by increasing crop yields on limited farmland. More than 70 percent of China’s cotton is genetically modified. The imported (often from the U.S.) soybeans it overwhelmingly uses are GM. Five years ago the government approved safety certificates for GM varieties of rice and maize, but further approvals for commercial growing are delayed and certificates could expire – thanks to anti-GM pressure.

Many Older Germans Taking Far Too Much Vitamin E, Magnesium, Not Enough Vitamin D

December 13, 2013: 12:00 AM EST
German scientists who investigated the prevalence of dietary supplement use among older people in the city of Augsburg found that those who took magnesium and vitamin were overdoing it. The data from men and women aged 65 and older showed that 54 percent of the women and 34 percent of the men take dietary supplements. In both sexes, scientists found, the ingested doses of magnesium and vitamin E frequently exceeded European Food Safety Authority tolerability standards. The doses were too high in 20 percent of the females and 33 percent of the males regularly taking magnesium and in 8 and 14 percent, respectively. Vitamin D, frequently recommended by doctors for this age group for bone health, was taken by relatively few older people.

Risk Of Kidney Stones, Linked To Obesity Problem, Can Be Reduced By Mild Exercise

December 12, 2013: 12:00 AM EST
Physical activity – even relatively small amounts of exercise – was associated with as much as a 31 percent decrease in the risk of kidney stones, U.S. researchers report. The study looked at information on dietary intake and exercise from 84,225 postmenopausal women gathered since the 1990s. The occurrence of kidney stones in women has risen significantly and has been linked to obesity, diabetes, metabolic syndrome and cardiovascular disease. But a little exercise goes a long way in preventing the painful condition, according to the researchers, who also found that consuming more than 2200 calories a day increased the risk of developing kidney stones by up to 42 percent.

Wolfberries Enhance Protective Effect Of Flu Vaccines Among Older Mice

December 11, 2013: 12:00 AM EST
U.S. scientists have shown in a study in older mice that ingestion of wolfberries, also known as Goji berries, improves the protective effect of flu vaccines. The researchers believe the berries increase the activity of dendritic cells important to the immune system’s ability to defend against viral infections. They said the results are important because they suggest that the berries have the potential to reduce age-related risk and severity of the flu virus in the presence of the flu vaccines. Flu vaccination is recommended for older people, but the vaccine is only 40 percent  effective in protecting older adults against infection

Dad’s Diet Prior To Offspring’s Conception Is Important To Fetal Health

December 10, 2013: 12:00 AM EST
What a man eats prior to the conception of his child can impact fetal and child development, according to a Canadian study in mice. Researchers compared the offspring of fathers with insufficient folate (vitamin B9) in their diets with the offspring of fathers whose diets contained sufficient levels. Paternal folate deficiency was associated with an increase – as much as 30 percent – in birth defects of various kinds in the offspring, compared to the offspring of mice whose fathers ate sufficient folate. Adequate folate – found in green leafy vegetables, cereals, fruit and meats – in a mother’s diet has long been known to prevent miscarriages and birth defects.

Reduced Dementia And Heart Disease Are Key Benefits Of Healthy Behaviors

December 9, 2013: 12:00 AM EST
Welsh researchers who studied 35 years of health data from 2,235 men aged 45-59 in South Wales found that those who consistently followed at least four of five healthy behaviors – regular exercise, non-smoking, low body weight, healthy diet and low alcohol intake – were much healthier than those who didn’t. Data showed that men who consistently followed four of five of the healthy behaviors were 60 percent less likely to suffer from dementia and cognitive decline, and 70 percent less likely to experience diabetes, heart disease and stroke than those who followed none of the behaviors.

Blood-Brain Barrier Finding Means Omega-3 Fatty Acids May Help Treat Alzheimer’s

December 8, 2013: 12:00 AM EST
Swedish research finds that omega-3 fatty acids in dietary supplements can cross the blood-brain barrier in people with Alzheimer's disease, affecting known markers for both the disease itself and inflammation. Earlier studies found evidence that omega-3 fatty acids protect the brain from Alzheimer’s, but the new findings strengthen the argument that omega-3s may benefit patients with certain forms of the seriously debilitating disease. Thirty-three patients participated in the study: 18 received a daily supplement; 15 received a placebo for six months. The results show that the omega-3 group – but not the placebo group – had higher levels of both DHA and eicosapentaenoic acid (EPA, another omega-3 fatty acid) in their cerebrospinal fluid and blood.

Faster Is Healthier When It Comes To Walking – Study

December 4, 2013: 12:00 AM EST
People who walk regularly for exercise generally assume that it’s healthful for them, even if they walk more slowly for longer periods of time, expending about the same energy as brisk walkers in  shorter periods of time. But now a large-scale U.S. study – data gathered from 7,374 male and 31,607 female participants who reported walking at a wide variety of speeds – found that faster  walking is more beneficial. The researchers cross-referenced the data against the National Death Index, finding that deaths since 1998 were disproportionately clustered among the slowest walkers (i.e., three miles an hour or slower). They  were especially vulnerable to dying from heart disease and dementia.

Alternating Days Of Low-Calorie And Regular Eating Has Health, Weight Loss Benefits

December 3, 2013: 12:00 AM EST
People who have tried intermittent food restriction – not quite strict feasting and then fasting – have found some health benefits in the practice, though most evidence so far is anecdotal. Intermittent restriction involves eating between 500 and 650 calories a day, every other day. On alternate days eating is normal. One 41-year-old man who has tried it for about a year – after a month-long “angry, grumpy” adjustment period – has lost 50 pounds, stopped taking medication for diabetes and no longer has stomach ulcers. A British study among three groups of overweight breast cancer patients found that two intermittent restriction groups lost twice as much weight as the daily calorie restriction group.

Review Of Clinical Studies Finds Exercise Benefits Elderly With Dementia

December 3, 2013: 12:00 AM EST
A British review of the findings of eight clinical trials involving 329 people finds that exercise benefits older people with dementia by improving their cognitive functioning and ability to carry out everyday activities. A review of data from six studies involving 289 people showed that exercise could improve the ability of older people with dementia to carry out daily activities, like walking short distances or getting up from a chair. The review authors acknowledged, however, that they did not find any clear effect of exercise on depression in older people with dementia. More evidence is needed to understand how exercise could reduce the burden on family caregivers and health systems, they said.

Regular Exercise Is Good For Creative Problem Solving

December 2, 2013: 12:00 AM EST
Researchers in the Netherlands have shown that regular exercise promotes two main pillars of creativity – divergent thinking (multiple solutions to a problem) and convergent thinking (a single correct solution). Infrequent exercise, however, does not have the same effect. The researchers gave thinking tasks to people who exercise at least four times a week and to people who do not exercise regularly. Turns out that physical movement is good for thinking flexibly, but only if the body is used to regular activity. In sedentary people, a lot of the energy intended for creative thinking goes to the exercise itself.

Study Demonstrates How Low Vitamin D Levels Damage The Brain

December 2, 2013: 12:00 AM EST
A new British study shows that vitamin D, which is important for bone health, is also important for the health of other tissues and organs, including the brain. Middle-aged rats fed a diet low in vitamin D for several months developed free radical damage to the brain, and many different brain proteins were damaged as identified by redox proteomics. The rats also showed a significant decrease in cognitive performance on tests of learning and memory. The researchers advised people whose vitamin D levels are low to eat foods rich in vitamin D, take vitamin D supplements, or get at least 10-15 minutes of sun exposure each day.

Diabetics Benefit More From Mediterranean Diet Without Breakfast

November 28, 2013: 12:00 AM EST
A Mediterranean diet that includes only a cup of coffee for breakfast -- and a calorie-packed but low-carb/low-fat lunch -- is better for type 2 diabetics, according to a Swedish study. The single meal, which includes wine and fats from olives and fish, does not induce higher blood glucose levels than a low-fat diet lunch. The food provided in the study had an energy content from carbohydrates that was intermediate between the low-fat and the low-carbohydrate meals. The researchers noted that a significant aspect of the Mediterranean diet is often forgotten: it usually skips breakfast.

Garlic Compounds Prevent Powdered Baby Formula Contamination

November 25, 2013: 12:00 AM EST
A Canadian study finds that two compounds in garlic – diallyl sulfide and ajoene – significantly reduce the contamination risk of a harmful bacteria sometimes found in powdered infant formula. Cronobacter sakazakii is a foodborne pathogen that causes a rare but often fatal infection in infants. It can poison a baby's bloodstream and lead to life-threatening cases of meningitis. Though equipment used to make milk products is typically cleaned with chemicals like chlorine, garlic compounds would provide a natural decontaminating alternative. "We believe these compounds are more beneficial in protecting babies against this pathogen," one researcher said.

Head And Neck Cancers May Someday Be Treated By Asian Vegetable Extract

November 18, 2013: 12:00 AM EST
Laboratory animal experiments by U.S. researchers have found that an extract of an Asian vegetable may have the potential to treat head and neck cancer, a frequently aggressive form of cancer that accounts for six percent of all cancer cases. The researchers showed in mice that extract of bitter melon, a vegetable commonly used in Indian and Chinese diets, reduced the head and neck cancer cell and growth. People in Asia use the vegetable in stir fries, salads, and juices. Head and neck cancers often start in the mouth, nose, sinuses, voice box or throat. They tend to spread from one part of the head or neck to another.

Further Benefits Of Low-Fat Diet Supplemented With Fish Oil For Prostate Cancer Patients

November 18, 2013: 12:00 AM EST
A low-fat – less than 15 percent – diet combined with regular intake of fish oil supplements (five grams a day) lowered the levels of inflammation-causing substances in the blood of prostate cancer patients. The diet also lowered the cell cycle progression score, a measure used to predict the recurrence of the disease. The study is follows up earlier research that found a low-fat diet with fish oil supplements eaten for four to six weeks prior to prostate removal slowed the growth of cancer cells in human prostate cancer tissue compared to a traditional, high-fat Western diet.

To Maintain A Healthy Weight, Be Consistent When Going To Bed, Getting Up

November 18, 2013: 12:00 AM EST
Research has consistently found that sleep is critical to reaching or maintaining a healthy weight. New research among women, however, has found that it’s not just about getting enough sleep:  going to bed – and getting up – at roughly the same time also have an impact on weight. The research among 300 women at two Western U.S. universities found that participants who went to bed and woke up at, or around, the same time each day had lower body fat. In fact, those with more than 90 minutes of variation in sleep and wake time during the week had higher body fat than those with less than 60 minutes of variation.

Reversing Obesity Also Reverses Premature Aging At The Genetic Level

November 15, 2013: 12:00 AM EST
Stanford University researchers who analyzed genetic data from 51 patients who had undergone bariatric (weight loss) surgery found that telomere length – chromosomal biomarkers that play a role in cellular aging – increased. This was in addition to declines in body mass index, excess weight, bad cholesterol, and inflammation levels. Researchers found a significant positive correlation between weight loss and telomere length and in increases in HDL, the so called "good cholesterol". The findings, which need further study, indicate that premature aging caused by obesity can be reversed at a genetic level through bariatric surgery and other means.

Posting Calorie Counts In Fast-Food Restaurants Doesn’t Change Eating Habits

November 15, 2013: 12:00 AM EST
Pres. Obama’s Affordable Care Act mandated that restaurant chains with more than 20 locations nationwide post the calorie content of all regular food and drink items on their menus. The idea, of course, was to encourage healthier food choices. Is the strategy working? Not according to a study by New York University researchers. Posting calorie content does not change purchasing habits or decrease the number of calories customers consume, especially among lower-income and less-educated consumers. The researchers said “more robust interventional policies” should be considered in neighborhoods where obesity is most prevalent.

Certain Herbs Improve Age-Related Cognitive Decline

November 15, 2013: 12:00 AM EST
A U.S. neuroscientist who tested the effect of different herbs on the brains of mice with age-related cognitive decline – a precursor of Alzheimer’s disease – compiled some interesting findings. She found, for example, that enhanced extracts from special antioxidants in spearmint and rosemary improved learning and memory in the test animals. There were also signs of reduced oxidative stress, a sign of age-related mental decline. The researcher acknowledged, however, that while spearmint and rosemary are probably beneficial for humans, there is still no way to tell how much would have to be consumed for people to see the same benefits. “In other words,” she said, “I’m not suggesting that people chew more gum at this point.”

Mediterranean Sauce Base Is Jam-Packed With Bioactive Micronutrients

November 15, 2013: 12:00 AM EST
A sauce used as a base in Mediterranean, especially Spanish, cooking is rich in bioactive compounds like polyphenols and carotenoids that help prevent cardiovascular disease and cancer, according to a study conducted in Spain. Researchers at the University of Barcelona identified the healthy antioxidants in sofrito –a blend of tomatoes, olive oil, garlic and onion –  using high resolution mass spectrometry. At least 40 polyphenols were found, including vitamin C, lycopene and beta-carotene. The researchers said eating 120 grams of sofrito a day, added to pasta for example, would provide a total intake of 16 to 24 milligrams of polyphenols per portion and 6 to 10 milligrams of carotenoids.

Coffee Reduces Risk Of Type 2 Diabetes, According To Studies

November 14, 2013: 12:00 AM EST
A report summarizing the latest research on the health effects of coffee says basically that drinking a few cups of coffee a day does reduce the risk of type 2 diabetes, although there is conflicting evidence on benefits of caffeinated versus decaffeinated coffee. The report said a couple of recent studies showed that drinking three to four cups of coffee a day lowered type 2 diabetes by 25 percent, compared to drinking none or fewer than two cups a day. One study said caffeine was probably not  responsible for the protective effect of coffee, while another found that regular but not decaffeinated coffee was much more protective against type 2 diabetes in women of all ethnic groups than in men.

Protein-Rich Breakfasts Curb Hunger Throughout The Morning

November 14, 2013: 12:00 AM EST
A study involving women (aged 18-55) found that the type of breakfast eaten has a lot to do with whether hunger pangs are experienced sooner or later in the day. High-protein breakfasts (e.g., sausage and eggs) stave off hunger longer, the U.S. researchers found, compared to low-protein (pancakes and syrup) breakfasts or no breakfast at all. Breakfasts in the tests all had the same number of calories (about 300), but the protein breakfasts contained 30 to 39 grams of protein. Protein eaters reported lower hunger, more fullness and less desire to eat after breakfast, and ate fewer calories at lunch.

Bariatric Surgery Performed At Non-Accredited Centers Is Far More Dangerous, Study Finds

November 13, 2013: 12:00 AM EST
U.S. researchers who analyzed data from 277,000 weight loss operations performed between 2008 and 2011 found that patients whose surgery was performed at accredited facilities were half as likely to die from the procedure. The mortality rate for bariatric surgery at an accredited surgical center was .08 percent, compared to .19 percent at a non-accredited facility. “This is not a small difference un outcomes,” the lead researcher said, noting that the study “reinforces that accreditation saves lives”. The study was released two months after the Centers for Medicare & Medicaid Services dropped its seven-year-old accreditation requirement for bariatric surgery facilities performing surgery on Medicare patients.

Make Healthful Snacks Available To Students, And Their Diets Will Improve

November 13, 2013: 12:00 AM EST
Students offered healthful, nutritious snacks in school – whether in vending machines or a la carte – tend to improve their overall dietary intake, according to new research. Michigan State University scientists tested standards similar to the USDA’s new Smart Snacks requirements scheduled to take effect in the summer of 2014. They found that schools that offered healthful snacks at lunchtime boosted students' overall daily consumption of fruit by 26 percent, vegetables by 14 percent and whole grains by 30 percent. Students also increased their consumption of fiber, calcium, and vitamins A and C.

Aerobic Exercise Improves Cerebral Blood Flow, Cognition, In Older Adults

November 12, 2013: 12:00 AM EST
It’s no secret that aging decreases mental efficiency and speeds memory decline, a major complaint of older adults. But new U.S. research confirms there is a tremendous benefit from aerobic exercise on memory and “can reduce the biological and cognitive consequences of aging”. For the study, men and women between 57-75 years old who were generally sedentary were assigned to either a physical training or a “wait-list” control group. The exercise group worked out on a stationary bike or treadmill for one hour three times a week for 12 weeks. Measuring cognition, resting cerebral blood flow, and cardiovascular fitness, researchers found that exercisers improved memory performance and had greater increases in brain blood flow to the hippocampus, the key brain region affected by Alzheimer's disease.

Some Vegetable Oils Do Not Help Lower Cholesterol Levels

November 11, 2013: 12:00 AM EST
Researchers who published a study on the content of vegetable oils urge the Canadian government to rethink its advice on the health benefits of corn oil and safflower oil. The two commonly used oils have been on a list of oils recommended because of purported cholesterol-lowering effects. But the researchers found that the two oils contain high levels of omega-6 linoleic acid, but almost no heart-healthy omega-3 α-linoleic acids. Labels on corn oil and sunflower oil products are allowed the claim: “a reduced risk of heart disease by lowering blood cholesterol levels”. That claim is not warranted in the case of omega-6 linoleic acids, the researchers argue.

Animal-Based Diet Increases “Acid Load”, Risk Of Type 2 Diabetes

November 11, 2013: 12:00 AM EST
The Western diet, which tends to be rich in animal products and other highly acidic (acidogenic) foods, induces an acid load on the body that can cause chronic metabolic acidosis and reduce insulin sensitivity, increasing the risk of type 2 diabetes, according to French researchers. In a study of more than 66,000 women, the researchers found that it didn’t matter where the acid load came from – though fruits and vegetables were not the problem – the higher the overall acidity of the diet, the greater the risk of diabetes. However, contrary to general belief, “Most fruits, such as peaches, apples, pears, bananas and even lemons and oranges actually reduce dietary acid load once the body has processed them.”

Artificial Trans Fats Are No Longer Necessary, Should Be Banned

November 11, 2013: 12:00 AM EST
Advanced technological societies no longer need synthetically produced trans fats, nutrition experts say, and the U.S. FDA was correct in urging that they be removed from the American diet. Trans fatty acids, made by infusing vegetable oils with hydrogen, were helpful at one time because the process increases shelf life and makes products like margarine more like butter. But now, because eliminating trans fats from the Western diet would prevent 10,000 to 20,000 heart attacks and as many as 7,000 heart disease deaths a year, they should be banned.

Popular Food Bloggers Come Up Short On Nutritional Recipes

November 7, 2013: 12:00 AM EST
U.S. researchers who analyzed the recipe recommendations of several popular food blogs found that many of the recipes were acceptable in calories, but excessive in saturated fat and sodium. The researchers noted that the meal photos on the six blogs were probably more attractive than the actual nutritional content of the foods. Another downside is that food companies sponsor the sites, so the recipes are actually advertisements for company products. “The public should be aware of the nutritional limitations of popular food blogs,” the researchers concluded. They recommended that dietitians help bloggers modify blog recipes and partner with bloggers “to improve the nutritional profile of recipes”.

“Tearless” Onion Is Easier On The Eyes, Promotes A Healthy Heart, And Helps Weight Loss

November 6, 2013: 12:00 AM EST
Scientists in New Zealand have developed an onion that makes a “tearless” sulfur compound similar to that found in garlic. Consumers who use the new onion in recipes not only avoid the tears associated with regular onions, they may also be providing the heart-healthy benefits associated with garlic eating. The scientists found in lab tests that tearless onion extracts significantly reduced blood platelet clumping (reducing the risk of heart disease), and had about the same anti-inflammatory properties as the regular version. Preliminary testing in rats also showed that the tearless onion could help control weight gain, more so than regular onions or garlic.

Obesity At Time Of Prostate Cancer Diagnosis Linked To Greater Risk Of Mortality

November 5, 2013: 12:00 AM EST
Overweight or obese men with prostate cancer are at a much greater risk of dying from the disease than men at a healthy weight at the time of diagnosis, according to a U.S. study. There is an even stronger mortality correlation between men with aggressive prostate cancer and obesity. Men who died from prostate cancer were 50 percent more likely to be overweight or obese at diagnosis compared to men who did not die of the disease. In fact, the researchers said, weight at the time of diagnosis was more strongly correlated with prostate cancer survival than many other factors studied by scientists in the past, including some prostate cancer treatments.

Celiac Disease Is Not The Only Allergy Associated With Wheat Consumption

November 5, 2013: 12:00 AM EST
Not all allergic reactions to wheat are caused by celiac disease, according to Italian researchers who studied data on 276 patients diagnosed with a unique disorder known as non-celiac wheat sensitivity (NCWS). In a double-blind, placebo-controlled wheat challenge, the researchers found that NCWS patients may be suffering from a non-lgE mediated food allergy, like celiac disease, that primarily affects the innermost layer of the GI tract. Symptoms are delayed, making it difficult to diagnose. NCWS symptoms involve the gastrointestinal tract, the nervous system, the skin and other organs. Symptoms disappear when wheat is excluded from the diet, and come back when  wheat consumption resumes.

Doctors Weigh In On Whether Sugar Consumption Contributes To Spread Of Cancer

November 2, 2013: 12:00 AM EST
Physicians at a Texas cancer center have issued a statement addressing some common misconceptions about how cancer spreads. One of the most common, and most fallacious, of these myths, is that eating sugar feeds the spread of malignant tumors. It doesn’t, the researchers said. Consuming sugar from natural sources – like fruits and vegetables – absolutely does no harm, and is in fact necessary for good health. But excess sugar in the diet, especially from processed foods, contributes to obesity and an increased risk of cancer. The doctors advised people to avoid processed sugars found in cakes, baked goods and desserts, and instead eat fruits that help “maintain a healthy weight and prevent health issues”.

Sun-Damaged Skin Can Be Prevented, Even Improved, Using Over-The-Counter Creams

November 1, 2013: 12:00 AM EST
U.S. researchers say that skin aging can be slowed, and skin that has already experienced the damaging effects of sun exposure can be improved. Prevention of skin damage – also called photoaging – caused by UVA and UVB exposure is easily done with daily application of 30-plus SPF sunscreen containing zinc oxide. Sun-damaged skin can be improved by daily application of retinol, derived from vitamin A. Retinol decreases the risk of skin cancer and improves skin pigmentation and abnormalities. It also increases collagen content, reducing lines and wrinkles. Lastly, a dermatologist can use a simple technique called fraxel resurfacing to improve wrinkles and pigmentation.

High Caloric Diet – Not Just Sugar Intake – Associated With Fatty Liver Disease

November 1, 2013: 12:00 AM EST
The serious liver condition known as nonalcoholic fatty liver disease (NFLD) is not associated with intake of sugar, according to a British study, but rather with a high caloric intake, no matter the source. Researchers said recommending a low-fructose or low-glycemic diet to prevent NFLD is therefore not justified. Instead, they found that a high-calorie diet, no matter the source of the calories, itself is more associated with the disease, and that a healthy diet and regular exercise are the best ways to prevent, and deal with, NFLD. “Our study serves as a warning that even short changes in lifestyle can have profound impacts on your liver," the researchers concluded.

Diet Someday May Be Used To Configure Gut Microbiota Toward Improving Human Health

November 1, 2013: 12:00 AM EST
Irish researchers report that the study of the human microbiota – trillions of beneficial bacteria in the gut belonging to a  thousand species – could transform scientific thinking about basic human nutrition, gut health and disease prevention: This has come about because of developments in DNA sequencing technology that have made possible closer analyses of complex microbial communities in the human digestive tract. Data from recent studies have shown that diet can program the gut microbiota and affect health status. Someday the  food industry might be able to design food ingredients and supplements that shape gut microbiota, improving consumer health.

“Health By Stealth” Strategy Could Lead To Nutritious Pizzas

October 31, 2013: 12:00 AM EST
Most of today’s commercially available – either the frozen grocery store or fresh-baked  pizza restaurant varieties – can be considered junk food, primarily because of excess salt and saturated fat. But the basic recipe for pizza – bread, tomatoes, and a little cheese – is essentially healthy. British researchers says pizzas, and other “nutritionally dubious foods”, can be restored to healthy status by reformulating without ruining the taste. The researchers did a little experimenting, and came up with a recipe using less salt; whole wheat flour; a little Scottish seaweed for flavor, vitamin B12 and fiber, iron, vitamin A, vitamin B12 and iodine; and red peppers for vitamin C. Both children and adult taste testers “gave it the thumbs-up for taste and attractiveness”.

Study Sheds Light On Effective Strategies For Keeping Weight Off After Successful Dieting

October 31, 2013: 12:00 AM EST
Dieters who have successfully lost weight can prevent the return of unwanted pounds by using anti-obesity drugs, meal replacements or a high-protein diet, according to new Swedish research. Scientists combined the data from 20 clinical studies involving more than 3,000 participants, who were either obese or overweight prior to dieting. The studies analyzed the impact of drugs, meal replacements, high protein diets, dietary supplements and exercise on rebound weight gain after completing low-calorie diets (less than 1,000 calories a day). Researchers found that anti-obesity drugs were effective but risky. In fact, the most effective drugs were are no longer on the market. However, “Meal replacement products and high protein diets are effective and available to everyone," they concluded.

European Diet Found To Be Deficient In Certain Vitamins And Minerals

October 31, 2013: 12:00 AM EST
A European study comparing recent data from dietary surveys conducted in eight countries has found that the European diet lacks 17 basic micronutrients. Conducted by the International Life Sciences Institute, the study found that vitamin D was the most severe deficiency, but diets also were low in iron, calcium, zinc, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B6 and folic acid. The researchers said that except in the case of vitamin D, low levels of vitamins do not pose a public health risk generally, but may in the case of specific age groups.

Inventor’s Meal Replacement Product, Backed By Venture Funding, Hits Market Soon

October 30, 2013: 12:00 AM EST
A 25-year-old San Francisco electrical engineer has developed – with the help of several million dollars in venture capital – a cheap, nutritious powdered meal replacement product. Though the product, known as “Soylent”, has its share of detractors, it has also won converts who say it is not only tasty and nutritious, it is not harmful. The inventor says his product is not meant to be a total substitution for regular healthy meals, but only as a “healthier, convenient alternative to takeout and rice and beans” – which he used to subsist on. Soylent will begin shipping in December to those who have preordered it. A week’s supply costs $65, or about $3 a meal.

Training Coupled With Coaching Improves Food Safety Compliance At Processing Plants

October 29, 2013: 12:00 AM EST
Alchemy Systems, a company that focuses on building safety cultures in food businesses, reports that training reinforced by corrective coaching by front-line supervisors can change employee behaviors and improve safety and productivity by as much as 26 percent. It’s a critical issue in the food industry, where recalls and highly-publicized contamination incidents have aroused consumer concerns about the safety of the food supply. The research was conducted at food manufacturing and processing plants in the United States over 15 months. The study found that the pre-training compliance rate was only 68 percent. After training, compliance improved to 82 percent. After three observations, compliance increased to 94 percent.

Moderate Physical Activity Every Day Helps Relieve, Prevent, Depression

October 28, 2013: 12:00 AM EST
Mild exercise – walking, gardening, etc. – for as little as 20-30 minutes a day is good for mental as well as physical health, according to new U.S. research. A systematic review of 26 years’ of scientific research – 25 clinical studies – found that regular moderate exercise not only helps relieve depression, it can help prevent the onset of depression later in life. “From a population health perspective, promoting physical activity may serve as a valuable mental health promotion strategy in reducing the risk of developing depression,” the researchers concluded.

“Hungry Girl” Enlisted By Potato Board To Change The Spud’s Image As A Fattening Food

October 28, 2013: 12:00 AM EST
Lisa Lillien, known to America’s weight-conscious masses as “Hungry Girl”, has partnered with the U.S. Potato Board to change the image of the humble spud as a dieter’s worst food nightmare. Lillien has an audience of millions who either get her email newsletter, routinely visit her Web site, or watch her TV show on the Food Network or the Cooking Channel. Her message is that food should be tasty and nutritious, but low in calories. That message dovetails neatly with the USPB's new ad campaign, “Guilt-Free Potato Goodness,” battling the “myth that potatoes are fattening”. Potato-lover Lillien has a track record of reaching USPB’s target audience: women 25 to 54 with kids under 18 at home.

Turn Off The TV At Dinner Time To Combat Family Obesity

October 28, 2013: 12:00 AM EST
Family meals and their rituals are an “underappreciated battleground” in the fight against obesity, according to U.S. researchers who looked at the link between family dinner rituals and body mass index (BMI) among 190 parents and 148 children. Parents participating in the study completed a questionnaire on the family’s mealtime habits; they were then weighed along with their children. Researchers found that a higher BMI among parents tended to correlate to frequently eating dinner while watching TV. Eating at the dinner table in the dining room or kitchen, however,  was linked to lower BMIs for both children and parents.

Omega-3 Intake: Too Much Of A Good Thing Can Be Bad For Health

October 28, 2013: 12:00 AM EST
Researchers have been touting the health benefits of omega-3 fatty acids for years. But a new U.S. study finds that there can be too much of a good thing. In an earlier study, mice fed large amounts of dietary omega-3s showed an increased risk of colitis and immune alteration. A new review of recent scientific literature has found that excess omega-3 fatty acids in the diet alters immune function sometimes in ways that lead to a dysfunctional immune response to viral or bacterial infections. The researchers urge people to eat omega-3-rich fish a couple of times a week. But those at risk for coronary artery disease should consult their doctors before taking supplements.

Americans Are Not Opposed To Nanofoods, But Want Better Labeling, Even If It Costs More

October 28, 2013: 12:00 AM EST
Do people care whether their food ingredients or food packaging are made using nanotechnology? Apparently so. They’re not opposed to nanofood or nanomaterials, they just want to be fully informed, and that means better labeling showing reliable, research-based information, according to a new U.S. study. Researchers told focus groups about the use of nanotechnology in food products and packages, then asked if they thought such products should be labeled. The answer was a definite yes, though participants were careful to note they did not oppose nanofoods, and they’d be willing to pay more for nanofoods if dependable information were made available.
