Natural Fish Oils Work Better Than Supplements To Reduce Blood Pressure In Lab Mice

March 5, 2013: 12:00 AM EST
Omega-3 fatty acids from oily fish like salmon – but not DHA found in fish oil supplements – helped lower blood pressure via vasodilation at ion channels in a mouse study. U.S. researchers showed that fish oil fatty acids regulate how ions such as sodium, potassium and calcium pass in and out of cells, affecting blood pressure. DHA in the dish oils rapidly activated the ion channels and lowered blood pressure in lab mice. In comparison, a dietary supplement, DHA ethyl ester, found in most fish oil pills, did not activate the same channels, and even antagonized the positive effect of DHA from natural sources. The findings emphasize the importance of obtaining omega-3 fatty acids from natural food sources such as oily fish.

Aerobic Walking Just As Effective At Reducing Lower Back Pain As Expensive Therapies

March 5, 2013: 12:00 AM EST
Scientists in Israel have determined that aerobic walking several times a week is as helpful in reducing lower back pain as expensive muscle strengthening regimens that require specialized equipment in rehabilitation clinics. An effective program involves walking two to three times a week for 20 to 40 minutes. Current muscle strengthening programs usually require specific equipment and supervised exercises. For the study, 52 patients with lower back pain were divided into groups that either took part in a clinic-based muscle strengthening program or an aerobic walking program. Both groups improved significantly in all areas of assessment, researchers said.

USDA Studies Probe Connections Between Stress Hormone, Decision Making And Dieting

March 1, 2013: 12:00 AM EST
USDA researchers are conducting studies to find out why some dieters succeed at losing – and keeping off – weight, while others fail miserably, time after time. One study is looking at patterns of decision making,another is evaluating the levels of a stress-associated hormone known as cortisol during dieting. They found that volunteers who lost the most weight had the highest scores in the Iowa Gambling Task (IGT), which tests decision making, differentiating good from bad, awareness of future consequences of current actions, and resisting short-term rewards in favor of longer term benefits. They also found that cortisol levels were the highest among those with the lowest IGT scores, indicating that dieting was probably a stressful activity.

Report Finds Significant Problems With U.S. Food Safety System

March 1, 2013: 12:00 AM EST
The statistics are staggering: foodborne diseases sicken more than 40 million people in the U.S. each year, causing 128,000 hospitalizations and 3,000 deaths, according to a new report from the Center for Biosecurity of UPMC. The cost? Medical expenses combined with lost productivity total $77 billion annually. To tackle this enormous problem, the U.S. needs effective surveillance of the food supply and rapid response to foodborne illness outbreak. It especially needs to quickly know the source of food contamination. Among a list of findings and recommendations, the Center urges Congress and the White House to fully fund both technology development and agencies whose job is to monitor the food supply. Perhaps most important: the Food Safety Modernization Act should be fully funded and implemented.

Limiting Exposure To Harmful Synthetic Chemicals May Be More Difficult Than We Thought

February 27, 2013: 12:00 AM EST
A U.S. study testing the levels of chemical contaminants in the urine of two groups of families, found that exposure to the chemicals may go far beyond what scientists have assumed. Even when participants consumed only organic foods prepared and stored in non-plastic containers, exposure to bisphenol A (BPA) and phthalates was significant. Previous studies have shown that phthalates and bisphenol A disrupt the endocrine systems of animals and humans and cause other health problems such as hyperactivity, anxiety, and depression in girls. "Current information we give families” – on plastic bottle labels and personal care products – “may not be enough to reduce exposures," said the lead author on the study.

Higher Levels Of Sugar In The Food Supply Linked To Higher Diabetes Rates

February 27, 2013: 12:00 AM EST
An analysis of data on sugar availability and diabetes rates compiled from 175 countries has found an association between increased sugar in a population’s food supply and higher diabetes rates and obesity rates. U.S. researchers said the data suggest that at the population level additional factors contribute to diabetes risk besides obesity and total calories intake. For every additional 150 calories of sugar available per person per day, the prevalence of diabetes in the population rose one  percent. “Sugar appears to play a prominent role” in the onset of diabetes, researchers said.

Mediterranean Diet Supplemented With Nuts, Olive Oil, Reduces Risk Of Cardiovascular Death

February 25, 2013: 12:00 AM EST
The Mediterranean diet supplemented with olive oil or nuts reduces the risk of a heart, attack, stroke or heart-related death, according to a long-term U.S. clinical study involving 7,447 people in Spain. After five years, scientists proved that participants who followed either of two types of Mediterranean diet – supplemented with either nuts or with olive oil – showed a substantial reduction in risk of suffering a cardiovascular event. The findings prove that a high-vegetable fat diet is healthier at a cardiovascular level than a low-fat diet. The diet is characterized by a high intake of olive oil, fruit, nuts, vegetables, and cereals; a moderate intake of fish and poultry; a low intake of dairy products, red meat, processed meats, and sweets; and wine in moderation, consumed with meals.

Maternal Supplementation With Omega-3 Fatty Acids Reduces Risk Of Low Birth Weight Babies

February 25, 2013: 12:00 AM EST
The first phase of a 10-year U.S. clinical trial found that the infants of women who received 600 mg of DHA (an omega-3 fatty acid) daily during their pregnancies were less at risk of low birth weight and premature birth. DHA (docosahexaenoic acid) occurs naturally in cell membranes with the highest levels in brain cells, but levels can be increased by diet or supplements. In the next five-year phase, the children will receive twice-yearly assessments until they are six years of age. Other developmental milestones will then be measured. The researchers hope that DHA supplementation will increase birth weight and gestational length to match those of Norway and Australia.

Asian Shirataki Noodles Catching On In West As Zero-Calorie Tummy Filler For Dieters

February 24, 2013: 12:00 AM EST
The world of dieting and weight control is catching on to the benefits of an old Asian food staple – shirataki noodles – as a way to fill one’s stomach without fear of overloading on calories. Marketed in the U.K. as ZeroNoodles and in the U.S. as Miracle Noodles, shirataki has no fat, no sugar and no taste, though before rinsing it has a slight fishy aroma. To make shirataki, tubers from the konjac plant are processed into a product called glucomannan flour. Marketers say a single 200 gram portion can replace rice, pasta or regular egg noodles on your plate, delivering only eight calories. Retailers in the U.K. are having a tough time keeping the store shelves stocked, according to news reports.

Diet Rich In Omega-3 Fatty Acids Significantly Reduces Risk Of Breast Cancer

February 21, 2013: 12:00 AM EST
A Canadian study in mice shows that consumption of omega-3 fatty acids on a regular basis over a lifetime significantly reduces the occurrence and size of breast cancer tumors. Mice fed a diet rich in omega-3 fatty acids developed only two-thirds as many tumors compared to the control mice. And the tumors were 30-percent smaller. "The fact that a food nutrient can have a significant effect on tumor development and growth is remarkable and has considerable implications in breast cancer prevention,” the researchers concluded.

Report Finds Widespread Mislabeling Of Fish In Markets, Restaurants, Sushi Bars

February 21, 2013: 12:00 AM EST
Nonprofit ocean protection group Oceana reports that about a third of 1,215 fish samples purchased in the U.S. between 2012 and 2012 were mislabeled, in apparent violation of federal guidelines. Samples in the study were bought at restaurants, markets and sushi bars in 12 areas of the country. Of 120 samples labeled red snapper, 28 different species were found, including 17 that were not in the snapper family. The study has implications for public health, as well. In New York, tilefish, which are known for their mercury content, was sold as red snapper, which the report called “one of the most egregious swaps”.

Study Determines Why Aspirin, Omega-3s Do A Body Good

February 21, 2013: 12:00 AM EST
U.S. researchers have figured out how low-dose aspirin and omega-3 fatty acids confer so many anti-inflammatory health benefits. Aspirin, they found, triggers the production of molecules called resolvins that are manufactured naturally by the body from omega-3 fatty acids. The resolvins – especially resolvin D3 – shut off the inflammation that is linked to destructive conditions like inflammatory lung disease, heart disease and arthritis. The researchers hope that investigators will now be able to study the pro-resolving and anti-inflammatory actions of resolvin D3 in other systems and eventually be able to tell which inflammation-associated diseases might be treated with D3.

Children Consuming Fewer Calories, According to National Study

February 21, 2013: 12:00 AM EST
Research on childhood food consumption patterns conducted by the federal Centers for Disease Control and Prevention has found that calorie intake for both boys and girls has dropped significantly from 1999 to 2010. Though the declines in daily calorie consumption were small – seven percent to 2,100 calories for boys and four percent to 1,755 calories for girls – researchers said the trend is definitely moving in the right direction. The declines were driven by a drop in carbohydrate consumption, researchers said. Calories from fat were stable, while calories from protein increased. The report is based on data collected through interviews.

U.N., Andean Countries Promote Awareness Of Quinoa’s Many Benefits

February 20, 2013: 12:00 AM EST
The U.N.’s Food and Agricultural Organization (FAO) has joined with officials from South American quinoa-growing countries to launch the “International Year of Quinoa”. Quinoa is grown in the arid Andean altiplano regions of Bolivia, Colombia, Ecuador and Peru, where it has been a food staple for thousands of years. Officials hope the International Year will raise awareness of quinoa’s value among the world’s small farmers because it is rich in essential amino acids and vitamins, and grows easily in most temperatures, altitudes, and moisture conditions. FAO says this versatility makes quinoa “a viable food option for areas with arid farming conditions and high malnutrition rates”.

Cereal Makers Target On-The-Go Breakfast Trend With New Drink Products

February 20, 2013: 12:00 AM EST
Kellogg and General Mills, known for their diverse lines of hot and cold breakfast cereals, are now targeting consumers who don’t have time to sit down to eat a bowl of cornflakes in the morning. They are jumping on the breakfast on-the-run bandwagon with breakfast drinks. Kellogg is rolling out “Breakfast To Go,” a milk-based drink. General Mills is testing a dairy-based breakfast shake – BFast – containing whole grains, fiber, protein, and vitamins. Meanwhile, the trend toward mobile breakfasts and snacks is not lost on Quaker Oats parent company PepsiCo, which offers a Quaker cereal powder drink in China and last summer began testing a similar drink in Brazil.

Carb-Rich Foods And Dairy Products Seem To Influence, Aggravate Acne

February 20, 2013: 12:00 AM EST
Diet plays a significant role in the aggravation of acne, according to new U.S. research. Scientists found that high glycemic load foods (containing higher levels of carbohydrates) and dairy products contribute especially to the problem, which afflicts more than 17 million Americans. Researchers reviewed scientific studies conducted between 1960 and 2012 that investigated diet and acne. The results do not demonstrate that diet causes acne, but seems to influence or aggravate it, the researchers said. They also noted that medical nutrition therapy (MNT) – including dietary intervention – could play an important role in acne treatment.

Study Finds No Link Between Antioxidant Consumption And Stroke Or Dementia

February 20, 2013: 12:00 AM EST
A 14-year U.S./Dutch study of more than 5,000 people over age 55 who had no signs of dementia at the beginning found that total antioxidant levels in the diet were not associated with the risk of developing dementia or stroke. Data – which contradict earlier studies about the link between antioxidant consumption and the risk of stroke or dementia – were gathered from annual questionnaires about how often 170 foods were eaten in the past year. About 600 people developed dementia and about 600 people had a stroke. But researchers found that people with high levels of antioxidants were no more or less likely to develop brain disease than people with low levels.

Food Authorities In The U.K. Begin Testing For Meat Products Contaminated With Horsemeat

February 19, 2013: 12:00 AM EST
As the horsemeat scandal continues to rock Europe, Nestlé announced that tests on nine processed beef products available in the U.K. – including products from the Jenny Craig weight-loss brand – had found no equine contamination. The company had earlier withdrawn beef and pasta products in Italy, Spain and France because it found traces of horsemeat. Meanwhile, the U.K.’s Food Standards Agency (FSA) said it will launch DNA testing next week of beef-based foods sold pre-packed or loose, including sandwiches, beef dripping, stock cubes, steak, stewing steak and ready meals that contain beef that is not minced. Officials in Parliament said various meat-based dishes had been withdrawn from eateries used by members, peers and staff.

Organic Tomatoes Have Increased Concentrations Of Sugars, Vitamin C, Lycopene

February 20, 2013: 12:00 AM EST
Though some studies have concluded that there is no evidence that organic farming produces more nutritious fruits and vegetables, a new study finds that tomatoes grown on organic farms  amassed more nutrients linked to stress resistance. According to the Brazilian authors, organic farming exposes plants to greater stress than conventional farming. The tomatoes they grew were about 40 percent smaller than conventionally grown tomatoes, but accumulated higher concentrations of sugars, vitamin C and pigment molecules like lycopene, an anti-oxidant compound.

Resveratrol Protects Against Hearing Loss Due To Long-Term Exposure To Noise

February 20, 2013: 12:00 AM EST
A U.S. study in rats shows that resveratrol – a powerful antioxidant compound found in red grapes and wine – eases or protects against the long-term effects of exposure to loud noises over an extended period of time. The researchers were studying resveratrol’s effect on bioinflammation, which is suspected of contributing to health problems such as Alzheimer’s disease, cancer, aging and hearing loss. The researchers concluded that resveratrol seems to protect against both noise-induced hearing loss and cognitive decline. Noise-induced hearing loss is a growing medical issue among American troops: more than 12 percent return from Iraq and Afghanistan with significant hearing loss.

Counseling On Diet, Nutrition In The Workplace Pays Significant Dividends

February 20, 2013: 12:00 AM EST
A pilot study conducted by Tufts University researchers found significant benefits to workplace intervention focused on dietary information and weight loss. Overweight and obese employees who participated in the intervention arm of the trial lost an average of 18 pounds over six months compared to members of the control group who gained an average of two pounds. The researchers said their approach is unique because it involves a “strong behavioral component": counselors trained in nutrition and behavior modification met every two weeks with participants to discuss menu planning, portion control, managing hunger, and dealing with stress-related and emotional eating.

Resistant Starches May Play A Role In Preventing Bowel Cancer

February 19, 2013: 12:00 AM EST
Indigestible starches – known as resistant starches – found in peas, beans and other legumes that are eaten at room temperature seem to help the body resist colorectal cancer by killing precancerous cells and reducing inflammation, a U.S. study has found. Resistant starches also lower bowel pH and transit time, and boost production of short-chain fatty acids, all of which promote good bacteria and fends off bad bacteria. The study in rats also found evidence that resistant starches may have implications for the prevention of breast cancer.

“Diet” Is The New Four-Letter Word In Food Industry Marketing

February 19, 2013: 12:00 AM EST
Market researcher Datamonitor’s database of new product launches in the food industry is showing a steady decline in the use of the term “diet” in product names. In 2009, new product labels featured the word diet 10.8 percent of the time. By 2012 that proportion had dropped to 6.6 percent. Food manufacturers are indeed acknowledging the obesity epidemic in the U.S. by “stealthily” introducing products lower in sugar, fat and salt. But in their labeling and advertising they are shunning the dirty word diet – “like the plague” – in favor of ”more positive messages” about food quality, protein, health and wellness, the researcher says.

Caffeine During Pregnancy Associated With Low Birth Weight, Longer Gestation Time

February 19, 2013: 12:00 AM EST
New research from Norway and Sweden finds a significant association between caffeine ingestion by pregnant women, longer pregnancies and low birth weight babies. The researchers looked at data gathered about mothers’ diet and birth details over ten years. Caffeine consumption in all forms – coffee, tea, fizzy drinks, and foods containing cocoa – was considered. Caffeine intake also increased the length of pregnancy, researchers found. Coffee (but not caffeine) was associated with an even longer gestational length – eight hours extra for every 100 mg caffeine per day. No link was found between caffeine consumption and preterm delivery, however, which is a major problem with expectant mothers who smoke.

Will Advanced Technology Someday Come To The Aid Of Dieters?

February 18, 2013: 12:00 AM EST
Whether or not the patent applications of inventors from The Netherlands, Israel and India ever reach the marketplace as viable products, they nevertheless provide some insight into the future of technology and weight control. The Dutch inventors came up with a video/computer system  that detects when a person is eating and announces “You are now eating”. This instant feedback is supposed to help them stop eating sooner. The Israeli inventors developed a sensor that detects the digestive process, alerts stomach muscle tissue, and induces satiation, vertigo or nausea. The Indian innovators built a refrigerator that monitors eating and drinking and offers obese people diet advice.

Taking Vitamin C During Heavy Exercise Reduces Impact Of Common Cold

February 13, 2013: 12:00 AM EST
A Cochrane Review of the results of five clinical trials has found that participants undergoing heavy short-term physical stress suffered less from colds when taking vitamin C supplements. A regular dose of one gram or higher a day of vitamin C reduced the average duration of colds in adults by 8 percent and in children by 18 percent. Vitamin C cut the incidence of the common cold among marathon runners, school children in a skiing camp and soldiers during a winter exercise. One randomized trial among adolescent competitive swimmers found that taking vitamin C cut the duration of colds in half for males, but had no effect on females.

Standing And Walking For Long Periods Can Be More Beneficial Than Short Bursts Of Exercise

February 13, 2013: 12:00 AM EST
A study by Dutch scientists has found that when people simply stand or walk for long periods of time – as much as two to four hours – their insulin levels were significantly improved compared to people who were strictly sedentary and people who were mostly sedentary but who exercised vigorously for one hour a day. Researchers found that when the number of calories burned is the same, longer durations of low-intensity exercise may offer more health benefits than shorter periods of intense activity. Insulin sensitivity and blood lipid levels help identify metabolic conditions like diabetes and obesity.

Computer Models Show Significant Long-Term Health Benefit Of Reducing Sodium Consumption

February 11, 2013: 12:00 AM EST
U.S. scientists who used three different computer models to project the overall impact of steady annual reductions (totaling 40 percent) of sodium consumption in the U.S. diet found that between 280,000 to 500,000 lives could be saved over 10 years. The optimum scenario would reduce sodium consumption to about 2,200 mg/day. Three research groups took different approaches for their simulations: one used observational cardiovascular outcome follow-up data; the other two inferred the cardiovascular effects of reducing sodium from data about the relationship of blood pressure to cardiovascular disease. “All three methods consistently show a substantial health benefit for reductions in dietary sodium,” the researchers concluded.

A comparison of vitamin D potencies among a variety of over-the-counter supplements has found that amounts listed on labels often do not match the actual contents. U.S. researchers who used an independent lab to analyze supplement contents said the amount of vitamin D ranged from nine percent to 146 percent of the amounts listed on the labels. The researchers said their biggest worry is that someone who has low levels of vitamin D in their blood and regularly takes a supplement with little vitamin D in it “could face health risks”. Americans spend $28 billion on vitamins, herbs, and supplements each year, according to the New England Journal of Medicine.

New Germicidal Plasma Technology Extends Shelf Life Of Food, Could Reduce Waste

February 11, 2013: 12:00 AM EST
Scientists in Scotland have developed a plasma technology that temporarily converts oxygen in sealed food packages to ozone, killing any mold, fungi or bacteria before the ozone reverts to its oxygen state. The method uses a retractable device that generates plasma. The device is held against the surface of plastic or glass packaging where it splits the oxygen molecules (O2), when then reform into ozone (O3) molecules. The researchers say the technology’s effectiveness as a germicide extends shelf life by about a day, which would go "a significant way to cutting down on the seven million tons of food discarded in the U.K. each year".

Restaurant Menus Packed With Calorie Information Influence Least Health-Conscious Diners

February 8, 2013: 12:00 AM EST
Despite legislative directives that restaurants list calorie content on their menus, there has been little agreement as to whether such informative menus have a positive effect on dining choices. In this U.S. study, researchers observed patron behaviors in a full service restaurant that provided three types of menus with varying levels of caloric information. They found that: calorie labels have the greatest influence on people who are the least health conscious; using a symbolic calorie label reduced the caloric intake of even the most health-conscious patrons; and calorie labels were more likely to influence the selection of the main entree rather than drinks and desserts.

Low-Cal Menu Items Boost Sales At Restaurant Chains

February 7, 2013: 12:00 AM EST
A study by the Hudson Institute's Obesity Solutions Initiative finds that restaurants that served more lower-calories foods experienced an average increase of 5.5 percent in same-store sales. Restaurant chains that sold fewer low-calorie items experienced a 5.5 percent decrease in sales. The group analyzed 21 fast-food and sit-down restaurant chains from 2006 to 2011. The report defined lower-calorie servings as sandwiches and entrees with 500 or fewer calories, beverages with 50 or fewer calories (per 8 ounces) and side dishes, appetizers and desserts with 150 or fewer calories. "The bottom line,” said the report’s author, “ is if restaurants don't get more aggressive behind these low-calorie products, they're leaving sales on the table."

Frequent Consumption Of Southern Cuisine Significantly Boosts The Risk Of Stroke – Study

February 7, 2013: 12:00 AM EST
Frequent consumption of fried chicken, fried fish, fried potatoes, bacon, ham, liver and gizzards – foods characteristic of Southern U.S. cuisine – significantly raises the risk of stroke, a U.S. study finds. Researchers who analyzed dietary data on more than 20,000 black and white adults found that the frequency of stroke was directly proportional to how much Southern food they ate. Those who ate Southern foods six times a week had a 41 percent higher stroke risk compared to those who ate it once a month. The Southern diet accounted for 63 percent of the higher risk of stroke among African-Americans above whites. Likewise, those who ate more fruits, vegetables, legumes and whole grains had a 29 percent lower risk of stroke risk than those who ate these foods less often.

Diet Rich In Fruits And Vegetables Can Help Reduce Acid Build-Up, Control Kidney Disease

February 7, 2013: 12:00 AM EST
A diet that is based on animal and grain products – like the classic Western diet – tends to be highly acidic and can lead to metabolic acidosis, a condition common in patients with chronic kidney disease (CKD). Now a study by U.S. scientists among 71 patients with advanced CKD found that adding either fruits and vegetables or an alkaline solution (bicarbonate) to their diets had a favorable response by reducing urinary kidney injury markers. The study suggests that these interventions in people with too much acid build-up could help maintain kidney health.

Kellogg Scientists Find That Presweetened Breakfast Cereals Are Healthy For Kids

February 6, 2013: 12:00 AM EST
A study by scientists at a Kellogg Company research unit found that children who start their day with cereal breakfasts – even presweetened ones, of which Kellogg produces many varieties – tend to have lower body mass indexes than children who eat no breakfast. They also found no differences in weight, BMI, waist circumference, blood pressure, or lipids among kids who eat presweetened ready-to-eat cereals or unsweetened cereals. The study was published in a bi-monthly, peer-reviewed journal on the nutritional care of children from birth through adolescence.

Sleep Duration Linked To Dietary Patterns

February 6, 2013: 12:00 AM EST
A U.S. study finds that certain nutrients seem to play a fundamental role in whether people sleep a long time or only a short time. The researchers say their data show that people whose diet is diverse and well-balanced – basically, a healthy diet – had the healthiest sleep patterns. Data were gathered from the CDC’s NHANE survey, which included dietary and health-related questions. Participants were grouped according to their usual; sleep pattern: very short (less than five hours), short (five to six hours), etc. Long sleep was associated with less intake of theobromine (found in chocolate and tea), dodecanoic acid (a saturated fat), choline (found in eggs and fatty meats), total carbohydrates – and more alcohol.

Omega-3 Fatty Acid DHA Proves More Useful In Treating Fatty Liver Disease – Study

February 5, 2013: 12:00 AM EST
A U.S. study in lab animals comparing two omega-3 fatty acids finds that onehad the greatest effect on nonalcoholic fatty liver disease. Researchers report that EPA did little to prevent the scarring (fibrosis) associated with nonalcoholic steatohepatitis (NASH). DHA supplementation, however, reduced the proteins involved in liver fibrosis by more than 65 percent. Liver inflammation and fibrosis are common problems growing steadily as the obesity problem worsens among Americans. "Based on these results, DHA may be a more attractive dietary supplement than EPA for the prevention and potential treatment of NASH in obese humans," researchers concluded.

Risk Of Type 2 Diabetes Increases With Exposure To Pesticides

February 5, 2013: 12:00 AM EST
Researchers in Spain have found that there is a direct relationship between exposure to pesticides (i.e., Persistent Organic Pollutants) in food, air and water, and the occurrence of type 2 diabetes in adults, no matter their age, gender or body mass index. The study analyzed concentrations of a specific group of pollutants in the adipose tissue of 386 adults. They found that the substances tend to concentrate in body fat, and might be one of the reasons obese people are more likely to develop diabetes, the researchers suggested, because the more fat the higher the concentrations of pesticides in the body.

Food Companies Are Mum On Use Of Nanoparticles In Their Products

February 5, 2013: 12:00 AM EST
As You Sow, a nonprofit corporate accountability group, reports that companies using nanoparticles in their food products have been less than forthcoming in making the public aware of it. The molecule-sized particles are entering the food chain in popular products and their packaging materials, the group says. Fourteen of 26 companies who responded to a survey – 2,600 companies received the survey – said they do not use nanomaterials. Various world regulatory bodies are grappling with the issue. Only the European Union has required labeling products if nanomaterials are present. Nanoparticles are said to be able to make products creamier without additional fat, and can intensify and improve flavors and brighten colors.

USDA Rules Encourage Healthier Snacks, Discourage Fat, Sugar, Sodium

February 5, 2013: 12:00 AM EST
In an effort to promote healthier snacks in school cafeterias, vending machines and snack bars, the USDA has proposed new standards, the “Smart Snacks in School” rules. The standards were required by the Healthy, Hunger-Free Kids Act of 2010. The proposed rules encourage snacks with whole grains, low fat dairy, fruits, vegetables or protein foods as their main ingredients, while discouraging snacks high in fat, sugar, and sodium. The rules allow some flexibility for different age groups in areas like drink sizes and caffeine content, as well as for “important traditions” like bagged lunches, birthday parties, holidays, etc., and fundraisers and bake sales. The public comment period for the rules is 60 days.

Vitamin D3, Omega-3 Fatty Acid DHA, Shown To Have Positive Impact On Alzheimer’s

February 5, 2013: 12:00 AM EST
U.S. researchers who conducted a small pilot study among Alzheimer’s patients found that vitamin D3 and the omega-3 fatty acid DHA regulate key genes and signaling networks in the brain. The compounds may someday play a role in boosting the immune system to control inflammation and improve plaque clearance. Amyloid plaques in the brain are the main characteristics of Alzheimer’s disease. The researchers suggested that supplementation with vitamin D3 and omega-3 fatty acids might need to be carefully balanced for each patient to help promote efficient clearing of amyloid-beta plaques.

Review Of Research Finds Strong Links Between Whole Grains And Health

February 5, 2013: 12:00 AM EST
A review by scientists in New South Wales of previous research has uncovered an association between whole grains and a reduced risk of type 2 diabetes, heart disease and high blood pressure. The scientists analyzed data from 11 major clinical trials completed in the last few years. The researchers used the data to create guidelines focusing on the ideal amount of whole grains that should be consumed, the nature of whole grains, and the potential mechanisms for the effect of whole grains on health. They suggested, for example, that the daily intake of whole grains should be 40 grams or more, approximately a bowl of whole grain breakfast cereal. Sounds easy enough, but unfortunately, 80 percent of the population falls short of this goal.

Vitamin D Levels Among Canadians Have Dropped Sharply Since 2009 – Study

February 4, 2013: 12:00 AM EST
Blood levels of vitamin D among Canadians are dropping dramatically across all age groups, according to a study by Statistics Canada, putting them at greater risk of serious disease. Canadians between the ages of 6 and 70 experienced a drop of 6.2 percent in average vitamin D levels between 2009 and 2011. The researchers encouraged implementation of public health action programs to urge vitamin D production and recommended that people get their vitamin D blood serum levels to between 100-150 nmol/L for best overall health and disease prevention

FDA Toughens Its Control Over Potentially Harmful Food Products

February 4, 2013: 12:00 AM EST
The U.S. FDA has issued food safety regulations that delete a requirement for hard evidence that a food product presents a health threat before it can be kept from the marketplace. The stronger final rules allow the FDA to detain food if it “believes” it is adulterated or misbranded. The agency can prevent the products from reaching the marketplace for up to 30 days while officials determine if further enforcement action, such as seizure, is required. The rules implement sections of the Federal Food, Drug, and Cosmetic Act under the Food Safety Modernization Act (FSMA). The act was signed into law by President Obama in January 2011.

New Technology Boosts Omega-3 Content Of Ground Beef

February 4, 2013: 12:00 AM EST
A U.S. scientist has developed a technique to enhance ground beef with omega-3 fatty acids, which have been shown to have a positive impact on heart disease, cholesterol and blood pressure. A Kansas company is now selling the enriched meat under the brand name GreatO Premium Ground Beef in stores in Buffalo, N.Y.  A four-ounce serving of the enhanced hamburger delivers 200 mg of omega-3s and tastes the same as regular ground beef, according to the scientist. The enriched ground beef offers an alternative to people who want omega-3s in their diet but don’t want to eat fish or take supplements.

Higher Intake Of Calcium Among Men Increases Risk Of Death From Cardiovascular Disease

February 4, 2013: 12:00 AM EST
Men are at much higher risk of cardiovascular disease (CVD) when taking greater amounts of supplemental calcium, according to a prospective U.S. study that analyzed diet and health data collected on 388,000 middle-aged men and women. The greater risk was not found among women, however. After an average of 12 years of follow-up, 51 percent of men and 70 percent of women were found to have taken calcium supplements. Men who took more than 1,000 mg/day of supplemental calcium had a significantly increased risk of total CVD death, especially from heart disease.

Higher Vitamin D Levels Decrease The Risk Of Adult-Onset Type 1 Diabetes

February 4, 2013: 12:00 AM EST
U.S. researchers who studied health data collected from eight million active-duty U.S. military personnel beginning in the 1980s found a significant association between adequate levels of dietary vitamin D and a reduced risk of adult-onset type 1 – or insulin-dependent – diabetes. The researchers said that the risk of type 1 diabetes seems to be higher even at vitamin D levels commonly regarded as normal. This suggests that a substantial proportion of the population could benefit from increased vitamin D intake.

Canadian Study Suggests That Middle-Aged Men Need More Protein To Maintain Muscle Mass

February 4, 2013: 12:00 AM EST
A study by Canadian researchers finds that middle-aged men need more than current recommended daily amounts of protein in their diets to maintain muscle mass that is lost with aging. The study measured muscle protein synthesis in 35 men who exercised but did not lift weights. Researchers found that eating a six-ounce serving of 85 percent lean ground beef significantly improved the rate of muscle protein synthesis following exercise. Canada’s Food Guide currently recommends eating about three ounces of meat per serving to provide adequate protein to maintain muscle mass.

Men Who Take Vitamin C Supplements Have Twice The Risk Of Developing Kidney Stones

February 4, 2013: 12:00 AM EST
Men who take vitamin C supplements regularly run a higher risk of developing kidney stones, according to Swedish research. The research analyzed data from 23,000 men who had no history of kidney stones and who took either no dietary supplements or supplements in the form of vitamin C only. The researchers found that men who take vitamin C supplements (typically 1000 mg per tablet) are twice as likely to develop kidney stones as men who do not take any dietary supplements. The risk increased with greater frequency of use as well. Regular use of multivitamins was not associated with the risk of kidney stones.
