Omega-3 Fatty Acids From Fish Oils Shown To Bolster Immune System

April 1, 2013: 12:00 AM EST
Scientists have known for some time that the omega-3 fatty acids (DHA and EPA) in fish oils can reduce harmful inflammation, but a new U.S. study shows they actually boost the immune system. The study in mice found that DHA-enriched fish oil enhanced white blood cell activation and antibody production. This bolsters immune responses associated with pathogens, and possibly dampens the entire inflammatory response. The immune-enhancing properties of fish oils could benefit people whose immune systems have been compromised, such as those with AIDS or with cancer undergoing radiation treatment.

Cash Rewards + Peer Pressure = Employee Lifestyle Change

April 1, 2013: 12:00 AM EST
Cash rewards offered by companies to their employees as an incentive to lead healthier lifestyles  can work, if the element of peer pressure is added, a U.S. study finds. The study is a timely one, because under the Affordable Care Act employers will soon be able to offer larger financial incentives for quitting smoking and losing weight. For the study, obese employees in one group  earned $100 every month in which they met weight loss goals. A second group was divided into smaller units, each member of which split $500 if monthly weight loss goals were met. But employees who met the goals could earn an extra $100 if other group members failed. The latter peer pressure approach led to greater average weight loss, researchers report.

“Reality Check” Urges Researchers To Avoid Hyping “Miracle Foods” For Preventing Cancer

April 1, 2013: 12:00 AM EST
Nutritional scientists and media professionals should be careful about publicizing single-study findings on the effects of so-called “miracle foods” on cancer risk, a “Reality Check” commentary by U.S. health scientists warns. The commentary mentions a show by TV’s Dr. Oz in which he said studies had shown that endive, red onion, and sea bass can decrease the risk of ovarian cancer by up to 75 percent. “However, the scientific evidence supporting these recommendations is limited,” the authors wrote. Researchers should be explaining to the public that miracle foods do not exist, but achieving and maintaining an ideal weight and regular physical activity are critical to lowering cancer risk, even though these are “not as ‘sexy’ as Dr. Oz would like.”

Omega-3 Fatty Acids From Fish Add Years To Lifespan Of Elderly – Study

April 1, 2013: 12:00 AM EST
Add older adults to the list of people who can benefit from eating omega-3-rich fish and seafood, a U.S. study says. In fact, people aged 65 and older can cut their mortality risk by as much as 27 percent, and their risk of death by heart attack by as much as 35 percent. Older adults with the highest blood levels of omega-3 fatty acids (DHA,DPA, or EPA) survived 2.2 years longer on average than those with lower levels. Researchers looked at 16 years of data from about 2,700 U.S. adults aged 65 or older who participated in a long-term heart study. DHA was most strongly related to lower risk of coronary heart disease; DPA with lower risk of stroke death; and EPA with lower risk of nonfatal heart attack.

American Consumers Are Worried About Sodium Intake, But Confused About How To Cut Back

March 31, 2013: 12:00 AM EST
Mintel reports that 58 percent of Americans say they monitor their salt intake at home, but are not necessarily buying less processed food or eating out less often – where the real salt threats lie. Seventy-two percent of consumers limiting their sodium intake say they cook with less salt and 64 percent say they add less salt to their meals. The researcher says these patterns show that Americans are confused about how to reduce sodium intake. Most of the sodium people consume comes from packaged foods and restaurant fare, “not what they are preparing at home”. Mintel advises restaurants and packaged food makers to enhance the flavor of low-sodium foods by using herbs and spices.

Americans See Nutrients As Important To Their Food Choices

March 31, 2013: 12:00 AM EST
Statistics from a variety of market researchers show that Americans are paying closer attention to the nutrient ingredients of the foods they purchase. The Food Marketing Institute says 33 percent more shoppers are buying foods and beverages because of their healthy components. A Gallup nutrition study finds that 86 percent of adults in 2012 “made a strong effort” to eat more nutrients, including vitamins, specialty ingredients, herbs and botanicals, and minerals. HealthFocus reports that 90 percent of adults say it is important to get nutrients naturally from foods. Nutrients now important to Americans: calcium, vitamin D, fiber, omega-3 fatty acids, choline, prebiotics, monounsaturated fatty acids, polyphenols/cocoa flavanols, and protein.

Canola Oils Found To Reduce Abdominal Fat, Lower Risk Of Metabolic Syndrome

March 29, 2013: 12:00 AM EST
The monounsaturated fats in canola oil and high-oleic canola oils appear to reduce abdominal fat, in turn reducing the risk of metabolic syndrome, U.S. researchers have found. For the randomized, controlled trial, 121 participants at risk for metabolic syndrome consumed a smoothie containing 40 grams (1.42 oz.) of one of five oils as part of a weight maintenance, heart-healthy, 2000-calorie per day diet. Results showed that those who consumed canola or high-oleic canola oils every day for four weeks lowered their belly fat by 1.6 percent compared to those who consumed a flax/safflower oil blend.

Eating Foods Rich In Fiber Reduces Risk Of All Types Of Stroke

March 28, 2013: 12:00 AM EST
Greater intake of fiber-rich foods – whole grains, fruits, vegetables and nuts – has been shown to reduce blood pressure and levels of “bad” cholesterol, both of which are risk factors of stroke. A new study that analyzed previously-published research has quantified the association, finding that a seven-gram increase in total daily fiber intake was associated with a seven percent drop in first-time stroke risk. There are seven grams of fiber in a serving of whole wheat pasta, plus two servings of fruits or vegetables. The eight studies involving more than 327,000 people were published between 1990-2012, and reported on all types of stroke.

Scientists Track Changes In Gene Expression Induced By Variations In Diet

March 28, 2013: 12:00 AM EST
In an animal study, U.S. researchers found that even the smallest changes in diet produce differences in gene expression linked to physiological changes. When transparent roundworms of the species C. elegans were fed different types of bacteria, their gene expression programs changed dramatically: one diet variation led to fewer offspring, shorter lives and faster development than a standard diet. The researchers said that use of a “very tractable system” like the roundworm may allow scientists to pinpoint precise questions about how certain foods could effect gene expression, physiological traits and disease in humans.

Americans Should Reduce Salt Intake, But There Is Confusion About Minimum Daily Levels

March 27, 2013: 12:00 AM EST
A U.S. review of studies conducted in the U.K. and Finland has found that national salt-reduction programs led to lower sodium intake, reduced blood pressure, and – in Finland – a 75 to 80 percent decline in death from stroke and heart attack. According to lead author Dr. Theodore Kotchen, Americans consume way too much salt and need to cut back to levels recommended by physicians and national guidelines. Kotchen notes, however, that because sodium is essential for life, it can be difficult to distinguish between what’s a necessary minimum intake and what is excessive. In terms of safety, the lower limit of salt consumption has not been clearly identified.

Compound Derived From Cod Inhibits The Spread Of Cancer In Lab Study

March 26, 2013: 12:00 AM EST
Following the trend of researching natural dietary products that could have anti-tumor potential, a U.S. study in lab animals has found that a peptide (protein) found in Pacific cod seems to inhibit the metastasis of prostate cancer. Polar fish, such as northern cod, express glycoproteins rich in an antigen that protects them from freezing. Using a special form of the antigen purified from Pacific cod, the researchers observed that it  prevents cancer cells from attaching to vessel walls – inhibiting spreading – and suppresses T-cell death, boosting the immune response. They said an understanding of how the antigens work could lead to development of foods that act as cancer therapeutics and agents for immunotherapy.

Protein-Rich Breakfast Reduces Evening Snacking, Study Shows

March 26, 2013: 12:00 AM EST
Eating a protein-rich – 35 grams of protein – breakfast significantly improves appetite control and reduces unhealthy evening snacking, U.S. researchers report. For the study, 20 overweight and obese women ages 18 to 20 followed one of three dietary regimens. One group skipped breakfast, another consumed a high-protein breakfast of eggs and lean beef, and one ate a normal-protein breakfast of ready-to-eat cereal. All portions had the same calorie content. Those who consumed the high-protein breakfast felt more full. In addition, there was a reduction in brain activity responsible for controlling food cravings. The high-protein breakfast group also snacked less in the evening on high-fat and high-sugar foods compared to those who skipped breakfast or ate a normal protein, ready-to-eat cereal breakfast.

Genetically Engineered Tomatoes Produce A Compound That Reduces Harmful Inflammation

March 23, 2013: 12:00 AM EST
U.S. scientists have genetically engineered tomatoes to produce a compound that provides the same health benefits as high-density lipoprotein (HDL), or “good cholesterol”. The engineered tomatoes produce 6F, a small peptide that mimics the action of apoA-1, the chief protein in HDL. Mice in the study lacked the ability to remove low-density lipoprotein (LDL or "bad" cholesterol) from their blood and ate a high-fat “Western-style” diet. Those that ate the peptide-enhanced tomatoes had significantly lower levels of inflammation; those not fed the tomatoes developed inflammation and atherosclerosis. The researchers said human consumption of genetically modified foods containing apoA-1-related peptides could someday help improve chronic conditions associated with harmful inflammation.

Anti-Inflammatory Foods Can Reduce The Risk Of Chronic Disease

March 22, 2013: 12:00 AM EST
A University of Alabama professor of personal health says the body’s natural response to injury – inflammation – is a good thing until it becomes chronic and out of control. That’s when it can lead to all sorts of health problems, including cardiovascular disease. Lauren Whitt says inflammation caused by obesity can be controlled through weight loss and eating the right kinds of foods. Among the anti-inflammatory foods she recommends: citrus fruits high in antioxidant vitamins C and E; dark, leafy greens high in vitamin K; tomatoes rich in the potent antioxidant lycopene; and wild-caught salmon, which is rich in omega-3 fatty acids. She also advised eating more foods straight from the farm and fewer processed and fried foods.

Churches Look For Alternatives To Glutinous Communion Breads

March 22, 2013: 12:00 AM EST
You’d think bread might have found sanctuary in churches from the gluten-free craze, but alas no. One Christian pastor was astonished to find that many in his congregation were abstaining from communion because of worries about gluten content of the communion breads and wafers. It’s not a big deal for most churches that can use various wheat substitutes, but it presents a tricky problem for Catholics: canon law requires communion bread to be made of wheat flour and water only. The enterprising Benedictine Sisters of Clyde, Mo., have had a solution for ten years, however: low-gluten – .01 percent or less – altar breads. Their customer base has grown over the decade from 200 to more than 6,000.

Book Details The Food Industry’s Role In Burgeoning Obesity Epidemic

March 22, 2013: 12:00 AM EST
Food companies have long been aware of people’s ingrained hankering for salt, sugar and fat, and have long profited from their awareness. Many of their unhealthiest products are crafted to appeal to those hankerings, and they are marketed – often to the most vulnerable audiences like children and the poor – without concern for their harmful effects, according to investigative report Michael Moss. His book “Salt Sugar Fat” describes the food industry’s deliberate development and marketing of “craveable” foods loaded with fat and sugar. “If you had any doubt as to the food industry’s complicity in our obesity epidemic,” says Washington Post reviewer Hannah Wallace, “it will evaporate when you read this book.”

People Who Are Seriously Mentally Ill And Obese Can Still Lose Weight – Study

March 21, 2013: 12:00 AM EST
People with serious mental illness often are overweight or obese. They have mortality rates two to three times higher than the general population. Many get no exercise and take several psychotropic medications that lead to weight gain. But these people can still lose weight, according to a U.S. study. Healthy behavioral changes involving simple nutrition messages, counseling and regular exercise can make a significant difference. The study involved 291 overweight or obese patients with serious mental illness who were randomly assigned to either an intervention group or a control group. After 18 months of weight management education and exercise classes, the intervention group lost an average of seven more pounds than the control group.

Toddlers’ Meals, Snacks Found To Be Loaded With Sodium

March 21, 2013: 12:00 AM EST
U.S. Centers for Disease Control scientists who tested 1,115 packaged meals and snacks for babies and toddlers found that almost three fourths of toddler foods had more than 210 mg of sodium per serving. Toddler meals tended to have much more salt per serving than baby foods: some had as much as 630 mg of sodium per serving. That’s about 40 percent of the daily amount recommended by the American Heart Association. The researchers said the less salt in a baby’s or toddler’s diet, the less they are likely to want in their foods as they grow older. Studies have shown that consuming excessive amounts of sodium is associated with the development of high blood pressure.

Whole Grains Can Easily Be Incorporated Into The American Diet

March 21, 2013: 12:00 AM EST
The Newton (Iowa) Daily News elaborates on suggestions from the Whole Grain Council on how Americans can easily boost whole grain content – to the recommended three to five servings daily – in their diet. Breakfast, for example, could include whole grain versions of waffles, pancakes, cereals, burritos, or even French toast. Whole grain snacks can include cereal mixes, popcorn or whole wheat tortillas with sliced fruit and peanut butter. A third of the flour in a recipe could be replaced with quick oats or old-fashioned oats; uncooked oats can replace bread crumbs in  meatballs, burgers and meatloaf. Last, and maybe easiest, try whole grain pastas and whole grain breads.

Way Too Much Salt In The Diet Of The World’s Population, Study Finds

March 21, 2013: 12:00 AM EST
The American Heart Association recommends a limit of 1,500 mg of salt per day; the World Health Organization recommends 2,000 mg. But a new U.S. study finds that 75 percent of the world population consumes an average of 4,000 mg of sodium daily through commercially prepared foods, table salt, and salt and soy sauce added during cooking. The researchers said they hope the findings will encourage national governments around the globe to “develop public health interventions to lower sodium”. Excess sodium intake raises blood pressure and can lead to cardiovascular disease, the number one cause of death in the world.

Natural Product Destroys Salmonella During Processing Of Ground Meat, Poultry

March 20, 2013: 12:00 AM EST
Despite recent recalls of fresh ground turkey and chicken due to salmonella contamination, demand for poultry products as a cheaper alterative to beef continues to grow. To provide an effective answer to the threat, Intralytix has developed SalmoFresh, a product whose active ingredients seek out and kill Salmonella, including the Heidelberg, Typhimurium, Enteritidis, Newport, Hadar, Kentucky and Thompson strains. Intralytix, which specializes in natural products that kill foodborne pathogens, says SalmoFresh works well on ground red meat and poultry. The meats are sprayed before grinding, resulting in significantly reduced Salmonella contamination. The FDA has granted SalmoFresh the status of GRAS (Generally Recognized as Safe).

Pediatrician Author Argues That Sugar –- Not Fat –- Is Making The World Obese

March 20, 2013: 12:00 AM EST
The real villain in the global obesity epidemic is not fat, but sugar, in all its forms, according to pediatrician Dr. Robert Lustig, whose book “Fat Chance: The Bitter Truth About Sugar”, has caused a stir in the U.S. Lustig has spent 16 years studying the effects of sugar consumption on the central nervous system, metabolism and disease. The oceans of sugary soft drinks that children and adults consume are as complicit as the mountains of burgers – made from corn-fed beef – in the obesity problem. Lustig says cheap sugar is difficult to avoid: it’s found in all kinds of foods. Why? Years ago food manufacturers, under attack for fat content in their products, replaced fat with sugar to make products more palatable.

How Virgin Olive Oil Helps Reduce The Risk Of Alzheimer’s Disease – Study

March 20, 2013: 12:00 AM EST
Scientists have known for some time that virgin olive oil plays a role in reducing the risk of Alzheimer’s disease in Mediterranean countries. Now U.S. researchers have figured out why: a compound known as oleocanthal protects nerve cells from Alzheimer’s damage. In a mouse study, researchers tracked the effects of oleocanthal in the brains and cultured brain cells of lab mice, finding that the substance boosted production of two proteins and key enzymes believed to be critical in removing dangerous beta-amyloid plaque from the brain. The Mediterranean diet – rich in olive oil use – “has the potential to reduce the risk of AD or related neurodegenerative dementias," the researchers concluded.

Lower Income People Can Stretch Their Food Dollars By Simply Eating Healthier Foods

March 20, 2013: 12:00 AM EST
A 34-week U.S. study finds that nutritious foods that roughly follow the Mediterranean diet are not only healthier for lower income families, they are significantly more economical. Sixty-three people from emergency food pantries and low-income housing sites attended six weeks of cooking classes, where instructors prepared quick and easy plant-based recipes based on olive oil, whole grain pasta, brown rice and fruits and vegetables. Changing the focus to fruits, vegetables, and healthy starches, and eliminating expensive items –  meats, snacks, desserts and carbonated drinks – was far more cost-effective for families on limited budgets. Participants not only cut their food spending by more than half, about half lost weight.

Asian Herbal Medicine For Weight Loss Can Do Serious Harm

March 18, 2013: 12:00 AM EST
Millions of people in Asia who regularly use herbal medicines to lose weight, or treat asthma and arthritis, are at risk of kidney failure and bladder cancer, according to British researchers who reviewed worldwide cases of a condition known as aristolochic acid nephropathy (AAN). The products -- available in China and other countries in Asia but banned in the U.S. and Europe -- are made using a botanical compound containing aristolochic acids. Because many cases of AAN go undiagnosed or misdiagnosed, the researchers proposed a protocol that would make it easier for physicians to diagnose the condition.

Vitamin D Deficiency Leads To Muscle Problems At The Cellular Level

March 18, 2013: 12:00 AM EST
A British study has found that low levels of the "sunshine vitamin" -- vitamin D -- affect muscle efficiency at the cellular level, explaining why people with low levels often experience fatigue. Vitamin D deficiency is a major public health problem because it not only impacts bone health, it also creates problems in the cell “power stations” known as mitochondria. The problems center on the use and recovery of the muscle-related compound phosphocreatine, a measure of mitochondrial efficiency. In the study, phosphocreatine recovery significantly improved after the patients took a vitamin D supplement for 10-12 weeks. All patients reported an improvement in symptoms of fatigue following supplementation.

Healthy Lifestyle Reduces Risk Of Heart Disease, Cancer

March 18, 2013: 12:00 AM EST
The same lifestyle patterns that lead to a healthier heart also reduce the risk of cancer, according to a new U.S. study. Being physically active, maintaining a healthy weight, eating a healthy diet, no smoking, etc., are all recommended by the American Heart Association as “Life’s Simple 7 Steps” to lower the risk of heart disease. Participants in the study begun in 1987 included 13,253 white and African-American men and women who were interviewed about their diet and other lifestyle factors. After 20 years, 22 percent were found to have cancer. Adhering to six or all of the seven factors reduced the risk of cancer by 51 percent, compared with participants who met none of the factors. Meeting just four factors led to a 33 percent risk reduction.

Study Finds That Remembering Recent Meals Helps Reduce Eating

March 18, 2013: 12:00 AM EST
British researchers who analyzed 24 studies on the effects of awareness and memory on food consumption found that remembering meals, being more aware of what’s being eaten, and paying attention to meals leads to eating less. The findings could improve weight loss programs, the researchers said, because simple awareness techniques can be adapted and taught easily. Writing down previous meals, using visual reminders of those meals, and even keeping food wrappers all help the remembering process.

Researchers who looked at weight gain trends among 11,000 children at age two and later at age four found no overall differences between those who drank skimmed or semi-skimmed milk and those who drank two percent or full fat milk. At both checkpoints, a third of the kids were  overweight or obese, probably due to TV watching and consuming sugary drinks. Drinking low fat milk didn’t confer any overall advantage, though the researchers said it is possible that overweight kids might have gained more weight had they not drunk it. Nevertheless, the American Academy of Pediatrics and the American Heart Association recommend that all children drink low fat or skimmed milk after the age of two to avoid excess weight gain.

Aromatic Compounds In Olive Oil Contribute To Sensation Of Fullness

March 14, 2013: 12:00 AM EST
A German study involving 500 participants found that natural oils and fats do a good job of regulating how full a person feels after eating. Olive oil in particular contributes to the sensation of fullness, primarily because of  aroma compounds. In one part of the study a group was given yogurt with olive oil aroma extracts, while a control group was given plain yogurt. The olive oil group’s calorie intake remained the same, but the control group had been consuming an extra 176 kilocalories per day. The control group had less of the satiety hormone serotonin in their blood, researchers said. Aroma compounds could pave the way for the development of more effective reduced-fat – and satiating – food products.

Regular Consumption Of Green Tea, Coffee, Reduces Risk Of Stroke

March 14, 2013: 12:00 AM EST
A 13-year study that followed more than 83,000 Japanese adults finds that those who drank at least one cup of coffee a day were 20 percent less likely to suffer a stroke. Those who drank two to three cups of green tea had a 14 percent lower risk, and those who drank four cups or more had a 20 percent lower risk. Those who drank at least one cup of coffee and two cups of green tea had a 32 percent lower risk of intracerebral hemorrhage (burst blood vessel in the brain) compared to those who rarely drank either beverage. The researchers surmised that regular tea and coffee drinking benefits cardiovascular health because partly because it keeps blood clots from forming.

Smoothies Containing Prebiotic Compounds Boost Calcium Absorption In Young Girls

March 14, 2013: 12:00 AM EST
Scientists from Purdue University and Dutch dairy cooperative FrieslandCampina have found in a study of 31 healthy adolescent girls that smoothies containing prebiotic galacto-oligosaccharides (GOS) changed the gut microflora, increasing bifidobacteria and significantly improving calcium absorption. The increase in calcium absorption was not linked to the level of GOS in the smoothies because calcium absorption improved whether the smoothies contained 2.5 g or 5 g of GOS. The girls drank the smoothies  twice a day for periods of three weeks. Increased calcium absorption may help reduce the incidence of osteoporosis, especially in postmenopausal women.

Healthier School Lunches Required By State Law Make A Positive Difference

March 12, 2013: 12:00 AM EST
New USDA National School Lunch Program rules require schools to provide healthier lunch options. U.S. researchers wondered if such state mandates make a difference to student eating patterns. In a study using data from the two states (at the time) that mandated a minimum number of servings of fruits and vegetables for high school students, researchers found that kids do eat at least a little healthier. The requirements had the most impact on students who had little or no access to fruits and vegetables at home. At the time the data were collected, the only states in the study that required minimum servings of fruits and vegetables were California and Mississippi.

High-Calorie Sugary Beverages Are Linked To Increased Consumption Of Unhealthy Foods

March 12, 2013: 12:00 AM EST
U.S. researchers who gathered data from a seven-year study of 11,000 children ages two to 18 showed that sugar-sweetened beverages (SSBs) were associated with higher caloric intake generally, and higher caloric intake from unhealthy foods. Both food and SSBs contributed to higher caloric intakes of adolescents who consumed more than 500 kcal of SSBs a day. The findings are troubling because many foods associated with higher SSB consumption (e.g., pizza, cakes/cookies/pies, fried potatoes, and sweets) are also among the main sources of solid fats and added sugars.

Study Associates Lack Of Sleep With Over-Eating And Weight Gain

March 11, 2013: 12:00 AM EST
Earlier studies have drawn the connection between lack of sleep and weight gain. But in a new U.S. study, researchers show while that staying awake longer burns a lot of calories, the amount of food participants ate while they’re awake more than compensates for the energy expended. Those who slept less also tended to eat smaller breakfasts and then binge on after-dinner snacks. Participants who slept only five hours a night over five nights – with unlimited access to food – gained on average nearly two pounds. The findings add further credibility to the theory that overeating at night may contribute significantly to weight gain.

Research Shows Statistical Link Between Caffeine Consumption And Low Birth Weight

March 11, 2013: 12:00 AM EST
A Swedish analysis of health data on more than 59,000 pregnant Norwegian women found a statistical correlation – but no cause and effect relationship – between consuming two cups of coffee a day and low birth weight babies. All of the participants in the study were healthy and had uncomplicated pregnancies. The researchers stressed that the study did not look at whether caffeine itself was responsible for the fetus being at greater risk. Nor did it examine whether the babies had any special health problems shortly after birth. They said more research is needed before drawing any conclusions about what the findings mean for pregnant women and their babies. The study found no relationship between caffeine consumption and premature birth.

Natural Appetite Suppressors Are Less Risky Than Pills, Nutrition Experts Says

March 8, 2013: 12:00 AM EST
There are “countless” products on the market these days catering to the desire of overweight or obese people to suppress their appetites as a technique for losing pounds. Unfortunately, says nutrition scientist Timothy Garvey, M.D., there is almost no reliable scientific data on the safety or efficacy of these products. “People buying these products are likely to be wasting money,” he warns. There are better, natural ways to decrease appetite, beginning with a protein-rich breakfast. Egg whites or low-fat yogurt will keep you feeling fuller longer because it takes the body more time to digest and absorb them. Later in the day, unsaturated fats will do the trick. The oleic acid in peanut butter or nuts helps quell hunger.

Whole Foods Market Says To Require GMO Labels On Products By 2018

March 8, 2013: 12:00 AM EST
Whole Foods Market said it plans to require all products at its stores in the United States and Canada to have labels indicating if they contain genetically modified organisms (GMOs) by 2018. Making the announcement at the Natural Products Expo West event, Whole Foods Market said it has been cooperating with many of its suppliers for several years to source products without GMO ingredients. In 2009, for example, the retailer began subjecting its 365 Everyday Value line to Non-GMO Project verification and encouraged its grocery suppliers to do the same.

Wrigley’s Enters Energy-Boost Market With Caffeinated Chewing Gum

March 8, 2013: 12:00 AM EST
With demand for chewing gum on the decline, and interest in energy-boosting foods and drinks on the rise, Wrigley’s, maker of the Juice Fruit and Doublemint gum brands, is introducing a new product packed with caffeine. Alert Energy Caffeine Gum will begin hitting shelves in convenience stores, supermarkets and mass retailers in April, even as concern grows among consumer groups and regulators about the safety of energy products, especially among teenagers. Wrigley says its target market for the caffeinated gum is consumers aged 25 and older, and its marketing plan will avoid associating it with other brands in its product line better known among kids and teens.

Sports Nutrition Emerges As Major Growth Category In Retail Food

March 8, 2013: 12:00 AM EST
Sports nutrition has emerged from the shadows of bodybuilding, steroids, banned substances, etc., into mainstream retail, according to researcher Euromonitor. The impact of this transformation on the category has been significant – growth is expected to approach 40 percent by 2017. Producers are developing products that appeal to non-traditional users with worry-free formulations, third-party certifications of safety and purity, convenient formats, emphasis on general fitness, and greater accessibility in supermarkets and other retail channels. Retailers have embraced sports nutrition by creating their own brands. Key example: Walgreen, whose larger stores now feature separate sports nutrition sections in the supplement aisles, offering for example two separate lines of protein powders, one of which is a store brand.

Weight Loss Can Prevent – And Treat – Inflammation-Related Conditions Like Arthritis

March 8, 2013: 12:00 AM EST
A review of scientific literature on the impact of shedding pounds on patients with arthritis has found that weight loss can lessen pain and restore function and quality of lifes, according to U.S. scientists. In addition, weight loss among obese patients could possibly avert about 111,000 total knee replacements every year. The researchers stressed that weight loss, through reduction of white adipose tissue, reduces an underlying cause of inflammation in the body. It therefore can help treat inflammation-related conditions like hypertension, insulin resistance and arthritis, and can help prevent their onset. Weight loss also reduces the stress on joints that leads to wear and tear and pain.

Nearly A Third Of American Adults Adhere To Gluten-Free Diet

March 7, 2013: 12:00 AM EST
Despite advisories from scientists that only people with severe allergic reactions to the protein gluten need buy gluten-free products, increasing numbers of American adults are cutting gluten from their diets, according to the NPD Group. Nearly 30 percent of U.S. adults are avoiding gluten, making it “the health issue of the day”. The trend has affected the restaurant industry: the number of consumers ordering gluten- or wheat-free products has doubled in the past four years. That adds up to more than 200 million restaurant visits in 2012. NPD Group advises restaurants to respond to this opportunity by training staff to accurately answer customer questions and use symbols on menus and menu boards to highlight gluten-free items.

Not Exactly “Toaster Ready”, But Faux Pop-Tarts Are Gaining In Popularity

March 7, 2013: 12:00 AM EST
A British bakery launched by a native Californian nostalgic for childhood favorite Pop-Tarts has re-created the pastry in a purportedly healthier format. “Our customers went wild for them,” says Arianna Halshaw, who is selling her version of the toaster pastry nationwide. It comes in only one flavor – strawberry – and has one drawback: you can’t put them in a toaster. The current tart trend seems to have begun in the U.S., where chic restaurants and cafés offer hand-crafted versions of the pastry introduced by Kellogg in the 1960s and still going strong, albeit with some new flavors like red velvet (190 cal.) and s’mores (200 cal.).

Could Financial Incentives Be The Key To Solving The Obesity Problem?

March 7, 2013: 12:00 AM EST
A study by U.S. researchers found that rewarding weight loss with dollars not only led to significant weight loss, it kept participants motivated to stick with the program longer. One hundred overweight or obese participants of all ages took part in the year-long study. All were given the goal of losing four pounds a month, then separated into four groups, two with financial incentives, two without. Participants were weighed monthly, and either given $20 for meeting the goal or fined $20 for failing. Sixty-two percent of the incentive groups completed the study, compared to 26 percent of the non-incentive groups. Mean weight loss among the incentive groups was 9.08 pounds, compared with 2.34 pounds for the non-incentive groups.

Short Bursts Of Exercise Have A Positive Impact On Higher Brain Functions

March 6, 2013: 12:00 AM EST
A Dutch meta-analysis of 24 studies on the impact of exercise on memory and other higher brain functions found that brief spurts of intense exercise positively affect self control among children through adults aged 35. Nineteen of the studies involving 586 participants analyzed the impact of short bursts of exercise, while five studies with 358 participants looked at the ieffect of  regular exercise. Regular exercise didn't have the same effect on higher brain functions, but the researchers acknowledged there were too few of them and the results were too inconsistent  to lead to firm conclusions. The higher brain functions include memory, concentration, planning, and decision-making.

Researchers Show Hormonal And Health Benefits Of Weight Loss On Overweight Women

March 6, 2013: 12:00 AM EST
U.S. researchers have found strong evidence that changes in hormonal signaling are among the main culprits in the links between body weight, lifestyle and the risks of developing cancer and other chronic illnesses. Adipose (fat) tissue produces hormones that affect metabolism, the researchers say. Two important ones are the anti-inflammatory hormone adiponectin, which increases the effect of insulin, and leptin, which can promote tumor cell growth. For the study, 439 overweight postmenopausal women were divided into groups that tried dieting, exercising or dieting plus exercising for a year. No matter which program the women followed, the more weight each participant lost, the more adiponectin levels increased and the more leptin levels decreased.

Folic Acid, Vitamin B, Ease Schizophrenia Symptoms Among Patients With Certain Genes

March 6, 2013: 12:00 AM EST
U.S. researchers have found that folate (folic acid) with vitamin B supplementation improves the negative symptoms of schizophrenia, especially in patients with certain genes. The study, involving 100 patients, focused on apathy, social withdrawal, and a lack of emotional expressiveness – all negative symptoms of schizophrenia. All participants were taking antipsychotic medications that ease positive symptoms (i.e., hallucinations and delusions) but not negative symptoms. They were randomly assigned to receive daily doses of either folate with vitamin B12 or a placebo for 16 weeks. All who received the supplements showed some improvement in negative symptoms. Researchers then looked at certain genes affected by the two nutrients, finding significant improvement in negative symptoms.

Abdominal Fat Linked To Increased Risk Of Colon Cancer

March 6, 2013: 12:00 AM EST
A U.S. study in mice shows that the risk of cancer is directly proportional to the amount of fat in the abdominal cavity. Scientists have known for some time that obesity boosts the risk of cancer. But in this study, researchers tested three groups of obese mice genetically engineered to be prone to colon cancer. They found that mice who were the most obese due to an unrestricted diet had the most visceral fat and the greatest number of intestinal tumors. When the visceral fat in some obese mice was removed surgically, the mice were still obese, but had significantly fewer tumors.

Green Tea Molecule May Provide Therapy For Alzheimer’s Disease

March 5, 2013: 12:00 AM EST
In a laboratory study, U.S. researchers have found that specific molecules in green tea extract control the generation of metal-associated amyloid-β aggregates associated with Alzheimer's disease. Epigallocatechin-3-gallate, also known as EGCG, prevented aggregate formation and broke down existing aggregate structures in the proteins that contained copper, iron and zinc. The research team – including chemists, biochemists and biophysicists – next plan to test the green tea molecule's ability to inhibit potential toxicity of aggregates containing proteins and metals in fruit flies.

Yam Bean-Based Breakfast Cereal Could Be Especially Helpful For Diabetics

March 5, 2013: 12:00 AM EST
Nigerian researchers report development of a ready-to-eat breakfast cereal from a legume with a low glycemic index, high fiber, and high amino acid and mineral content. The cereal’s key ingredient is African yam bean, but also includes maize and coconut extract. Yam bean is valued because of its benefit for diabetics: it is slowly digested, leading to a very gentle rise in blood sugar. But the bean is difficult to cook with. The researchers say an African yam bean-based ready-to-eat cereal, produced on an industrial scale, could provide widespread nutritional benefits for vulnerable groups, especially diabetics.
