Study Finds One In Three Nestlé Employees In Sydney Lacks Vitamin D

One in three Australian office workers is lacking in vitamin D during the summer, according to a joint study by Nestlé and the University of Sydney. Results showed that 42% of the 104 male and female employees at the company's Australian headquarters had record low levels of the essential micronutrient by the end of winter. The findings alarmed the researchers, because vitamin D deficiency makes people more likely to suffer from reproductive health problems, muscle function disorders, and osteoporosis.  Nestle used the results to showcase its vitamin D fortified Sustagen and Nestlé Malted Milk Powder.

Probiotic Reduces Food Transit Time, Improves Gastrointestinal Health

A multinational team of scientists who tested the effects of daily supplementation with a specific probiotic on 100 people found that Bifidobacterium lactis HN019 reduced the transit time of food through the intestines in healthy individuals by as much as 33 percent. The participants, whose mean age was 44, received either high or low doses or B. lactis HN019, or a placebo, for 14 days. The researchers said that both the low and high dose groups experienced improvements in nausea, vomiting, regurgitation, abdominal pain, flatulence, constipation and diarrhea. The researchers said that reducing gut transit time could over a long period of time significantly reduce the risk of various colorectal problems, including cancer.

Study Shows Older Adult Americans Consume More Phytonutrients

Older adult Americans (65 years and older) consume more phytonutrients, such as carotenoids and flavonoids, from fruits and vegetables, according to the Nutrilite Health Institute's analysis of data from the U.S. Department of Agriculture's National Health and Nutrition Examination Surveys (NHANES). Older adults consumed 20% more carotenoid, 40% more flavonoids, and 80% more ellagic acid than their younger-adult counterparts. The study focused on 14 phytonutrients and covered a study population that included "non-pregnant, non-lactating" respondents who are 19 years and older. Respondents were asked to perform two dietary records based on NHANES criteria. Results showed that resveratrol intake among older adults was 50% higher compared with younger adults, while both age groups showed similar levels of lycopene intakes.

FDA Proposes Revamping Its System For Monitoring, Regulating Imported Goods

Reacting to the explosion of imported, FDA-regulated products, materials and ingredients, the agency has proposed reforms designed to better protect the health of American consumers. The problem is getting worse, thanks to rising productivity among Western economies, growing global demand for products, and faster and easier transfer of goods across borders. The four key reforms include partnering with international regulators, developing international data information systems and networks, developing an information gathering system focused on risk analytics, and working with public and private third parties and industry “to allocate FDA resources based on risk.” We can no longer rely on historical tools, activities and approaches,” said Acting Principal Deputy Commissioner of Food and Drugs John M. Taylor.

Studies Suggest That Dieters Using Sugar Substitutes May Be Getting The Opposite Result

Researchers who analyzed health and diet data from 474 participants in a longitudinal aging study found that diet soft drink consumption was associated with increased waist circumference in humans. A second study in mice found aspartame raised fasting blood sugar levels in diabetes-prone mice. Taken together, the studies suggest that people who turn to diet beverages and other foods containing sugar substitutes as a weight loss measure may be getting the opposite result. In the human study, diet soft drink users, as a group, experienced 70 percent greater increases in waist circumference compared with non-users. Findings of the animal syudy suggest that heavy aspartame exposure might potentially directly contribute to increased blood glucose levels, and increased risk of diabetes, the researchers concluded.

Vitamin E-Rich Palm Oil Boosts Good Cholesterol, Lowers Risk Of Heart Disease

Scientists in Malaysia have found that a six-month regimen of daily supplementation with tocotrienol-rich palm oil raised blood levels of HDL cholesterol among older adults just three months into the program. The vitamin E supplement improved the ratio of HDL cholesterol to total cholesterol by as much as 14 percent compared to five percent in a placebo group. These findings indicate that vitamin E-rich palm oil could help lower the risk of cardiovascular disease, because increases in HDL cholesterol have been linked to a 22.5 percent reduction  in  cardiovascular events.

Extreme Weight Control Behavior In Adolescence Continues Into Adulthood – Study

Dieting adolescents who develop extreme weight control behaviors and binge eating are likely to continue these harmful activities into adulthood, U.S. research has found. The researchers analyzed data from a 10-year longitudinal study that examined eating, activity, and weight-related variables among more than 2,000 young people. Among females, the use of extreme weight control behaviors increased from 8.4 percent to 20.4 percent between early adolescence and early young adulthood and from 12.6 percent to 20.6 percent between middle adolescence and middle young adulthood. Extreme weight control behaviors among males increased from 2.1 percent in middle adolescence to 7.3 percent in middle young adulthood. The findings point to a need for “early and ongoing efforts aimed at the prevention, early identification, and treatment of disordered eating behaviors in young people," the researchers concluded.

Vitamin A Supplementation In Early Childhood Does Not Prevent Asthma Later In Life

Scientists in the U.S. and Nepal who analyzed data from two studies involving more than 5,000 children and pregnant women who took vitamin A supplements found that, after 15 years, the vitamin had no impact on whether asthma developed. In one study preschool children were given either vitamin A or a placebo. In the second study, one-third of the mothers took vitamin A before, during and after pregnancy, and one-third took no supplement. Ten to fifteen years later the researchers used questionnaires and tests to detect the presence of asthma. The results showed no difference between the groups of children, all of whom lived in a rural area of Nepal where chronic malnutrition is common.

Food Allergies Among U.S. Children Worse Than Previously Reported

A study has revealed that 8% of children in the United States have food allergies, considerably higher than previously estimated. Analysis of data gathered for 40,104 children showed that peanut, milk, and shellfish are the top allergen-linked foods. Age, geographic location, income, and race play significant roles in the odds of having food allergies. Researchers also observed discrepancies in food allergy diagnosis according to ethnic origin and family income level.

Resveratrol Helps Seniors Deal Better With Old Age

A review of studies focusing on the effects of resveratrol on humans revealed that the polyphenol compound may not avert the onset of old age, but might help people to deal with it better. Many studies have focused on the anti-aging, anti-carcinogenic, anti-inflammatory, and anti-oxidant properties of resveratrol; however, related human clinical tests are scarce since very few published human studies have focused on resveratrol's ability to achieve the physiological gains described in laboratory tests.

Mango Helps Cut Body Fat And Control Body Fat In Mice

Adding mango to a diet can help lower body fat and control blood sugar, according to an animal study at the Oklahoma State University's College of Human Environmental Sciences.  Researchers looked at the efficacy of the Tommy Atkin, the variety most commonly available in the U.S., in moderating blood glucose and lipid levels in mice. Results showed mango lowers glucose and cholesterol levels and affects factors that play a role in fat metabolism, such as the circulating level of the hormone leptin. The research, which was funded by the National Mango Board, also pointed out that mango has a lot of nutrients and "bioactive compounds" that offer beneficial effects.

Regular Olive Oil Consumption Found To Protect Older People From Stroke

French scientists have found evidence that regular use of olive oil for both cooking and as a dressing can significantly reduce the risk of a stroke in older people. The researchers analyzed the medical records of 7,625 people ages 65 and older. None had a history of stroke. They categorized the subjects by no use of olive oil, moderate use (in cooking or dressing) or intensive use (in cooking and dressing). Over five years, those who regularly used olive oil for both cooking and as dressing had a 41 percent lower risk of stroke compared to those who never used olive oil. “These results suggest a protective role for high olive oil consumption on the risk of stroke in older subjects,” the researchers concluded.

High-Protein, Low-Carb Diet Slows Tumor Growth, Reduces Risk Of Cancer

A Canadian study in mice has found that the risk of cancer is significantly reduced by eating a diet low in carbohydrates and high in protein. The researchers implanted different strains of human or mouse cancer cells in the mice, then fed them either of two diets. The Western-style diet comprised 55 percent carbohydrates, 23 percent protein and 22 percent fat. The other, which approximated the South Beach diet, comprised 15 percent carbohydrate, 58 percent protein and 26 percent fat. Tumor cells grew consistently slower on the high-protein diet, researchers found. And half of mice genetically engineered to breast cancer that ate the Western diet developed breast cancer in their first year of life. None of the high-protein diet mice developed cancer.

Lutein Protects Eye From Adverse Effects Of Exposure To Light

A study with mice by Japanese researchers revealed that Lutein supplements may help protect the eye from potentially damaging effects of strong light. Researchers analyzed the effects of light on the retinas of a group of Balb/c mice fed with a lutein-enhanced diet and another group fed a normal diet. Exposure to light increased the presence of γ-H2AX, a double-strand breaks (DSBs) marker in DNA, in photoreceptor cells. Lutein, however, eased this up-regulation. Also, lutein diet increased the expression of eyes absent (EYA), which supports DNA repair, and cells' health and survival.

Delaying Introduction Of Allergenic Foods To Young Children Has No Significant Benefit

Children from infancy through age four who were fed typical allergenic foods such as cow’s milk and peanuts were no more likely to show symptoms of allergies than children who were denied such foods, new Dutch research has found. The study tracked eczema and asthma symptoms of 7,000 children who were introduced to cow’s milk, hen’s egg, peanuts, soy and gluten before they were six months old. “This study does not support the recommendation for delayed introduction of allergenic foods after age six months for the prevention of eczema and wheezing,” the researchers concluded.

DASH-Guided Diet Helps Adolescent Girls Keep Off The Pounds

A study revealed that adolescent girls whose eating habits were patterned after the Dietary Approach to Stop Hypertension (DASH) dietary guidelines gained less body mass index (BMI) over a 10-year period. Researchers used longitudinal mixed modeling techniques to assess the impact of DASH food groups and a DASH-compliance scale on BMI gains of 2,327 girls. Fruit and low-fat dairy intakes were lead indicators as BMI gain predictors, while whole grain was more weakly correlated with lower BMI gain.

Beneficial Affects Monounsaturated Fatty Acids From Fish Oil Shown On Mice

A study on mice demonstrated the benefit of monounsaturated fatty acids (MUFAs) in lowering metabolic syndrome risk.  Researchers divided male mice into a control group that was fed a 32% lard diet and another group fed with 27% lard and 5% saury-oil-derived MUFA rich in C20:1 and C22:1 isomers diet for six weeks. Results show mice fed with the MUFA diet had better insulin resistance, with metabolic syndrome risk factors lessened by decreasing blood glucose and lipids. Improvement in adipocytokine profile may account for these beneficial changes.

Eating Foods Made With Fat Substitutes Contributes To Weight Gain

A U.S. study has demonstrated that consuming foods processed with synthetic fat substitutes actually contributes to weight gain and obesity. For the study, rats were fed a diet of either high-fat or low-fat chow. Half of the rats in each group were fed high-calorie, high-fat potato chips, while the other half were fed either high-calorie chips or low-calorie chips made with the artificial fat olestra. Rats fed the high-fat diet who ate both types of chips ended up eating more food, gaining more weight and developing more fatty tissue than rats that ate only the high-calorie chips. The researchers said that their findings indicate that “a diet that is low in fat and calories might be a better strategy for weight loss than using fat substitutes."

Selenium Seems To Prevent Cell Oxidation In Overweight People Who Exercise

Overweight people who work out may benefit from a daily supplement containing the macronutrient and antioxidant selenium because it significantly decreases levels of lipid hydroperoxides, an indicator of oxidative damage to cells, after exercise, a British study has found. Ten normal weight and ten overweight people participated in the randomized double-blind study in which they took 200 micrograms of sodium selenite or a placebo every day for three weeks. After three weeks the groups switched regimens. Selenium supplementation was associated with a 0.25 micromole per liter decrease in lipid hydroperoxide levels in the overweight group following exercise.

Drinking Sweet Beverages Desensitizes People To Sweetness, Causing Overconsumption

Frequent consumption of sugary drinks dulls the sensitivity to sweetness, leading people to seek more sweet foods and drinks and a “vicious cycle” of consumption, according to a British study. For one part of the study, researchers assessed 22 lean and 11 overweight participants on the intensity of sweet taste, finding that overweight and obese people tended to rate identical drinks as being less sweet than lean people. The authors concluded that sweet “treats” become less rewarding over time, pushing people to look for even sweeter foods and drinks. In the second study, 12 lean people who rarely drank sugary beverages consumed soft drinks for four weeks along with their regular diet. The sugary drinks altered sweet intensity/pleasantness ratings and increased the preference for sweetness in these “sucrose dislikers.”

Study Finds That Drinking Caffeinated Coffee Is Not A Risk Factor For Cardiovascular Disease

A multinational team of researchers who studied health data from 11,697 women with cardiovascular disease found that drinking a few cups of caffeinated coffee each day does not increase or lower the risk of dying from a second heart attack or stroke. Over 24 years of follow-up (1980-2004) the researchers documented 1,159 deaths, 579 of which were caused by cardiovascular disease (CVD). However, caffeine intake was not associated with the total number of deaths, nor with the deaths from CVD. "Our results suggest that coffee drinking is okay for patients with cardiovascular disease,” the researchers concluded, but cautioned that it would be best to conduct similar studies in other populations.

Both Plant And Animal Protein Are Effective At Controlling Appetite

The source of protein in a person’s diet, whether from animals or plants, makes no difference to whether it is effective in controlling appetite or promoting weight loss, according to a review of scientific literature. Studies have shown that a diet high in protein contributes to feelings of fullness or satiety, energy burning and fat loss. Consumption of protein also helps keep weight off, the researchers noted. The review by Danish and Canadian researchers found that animal proteins, particularly dairy proteins, are superior to plant proteins for building muscle, but found no evidence indicating that the source of the protein made any difference in weight loss.

Change In Nutrient Load Has Prompt Effect On Gut Bacterial Community Structure

Researchers have found that change in nutrient load can have immediate impact on the gut (fecal) bacterial community structure. The study focused on how gut bacterial community structure reacts to changes in the nutrient load in lean and fat subjects, as well as on the possible correlation between the subjects' microbiota and the efficacy of dietary energy harvest. Pyrosequencing bacterial 16S ribosomal RNA genes present in the feces of study subjects enabled researchers to study dynamic changes in gut microbiota during changes in caloric content of diets.
