Food fortification aids nutrient intake

foods-1003976In a recent national dietary survey published in the Journal of the Academy of Nutrition and Dietetics, researchers analyzed the diets of over 7,000 children and adolescents between 2 to 18 years old. Nutrient content of each food and supplement consumed in each child’s diet was calculated and compared to the Estimated Average Requirements (EAR). The results found that boys and girls between the ages 2 to 8 had the lowest levels of inadequate nutrient intake while girls between the ages 14 to 18 had the highest levels of inadequacy. Vitamin D, thiamin, and folate in fortified foods were the highest contributors of at least half of the nutrient intake. Other nutrients that contributed to at least 12 to 18 percent of the intake were vitamin A, vitamin C, riboflavin, niacin, B-6, B-12, iron, and zinc. Calcium was among the lowest at 4.5 to 6.6 percent. Despite the increased nutrients in fortified foods, a significant percentage of children did not meet the EAR for their age and sex. What are your recommendations to your patients for maintaining a healthy diet?

Regulation of fast food chains may prevent rise in obesity

classic-hamburger-sandwich-and-fries-100188748A recent article published in the Bulletin of the World Health Organization compared the number of fast food transactions in 25 high income countries with changes in the average body mass index of each country. Between 1999 to 2008, the average number of fast food transactions per capita increased from 26.61 to 32.76 and the average BMI increased from 25.8 to 26.4. In addition, researchers found a correlation between the country’s economic freedom and the number of fast food transactions. Countries that are more economically free have a greater increase in the average number of fast food transactions. Government regulation of fast food intake can potentially prevent the rise in obesity especially in developing countries. What are your thoughts about this article? How do you encourage your patients to limit food from fast food restaurants?

Excess added sugar intake tied to death

crepe-cake-100194838In a recent study published in JAMA Internal Medicine, researchers from the Centers for Disease Control and Prevention found that participants who consumed more added sugar in their diet were more likely to die of heart disease. Of the 31,000 U.S. adults surveyed between 1988 and 2010, an average of 15 to 17 percent of their daily calorie intake was from added sugars. This is greater than the recommended amount set by the American Heart Association of 100 calories of added sugars per day for women and 150 calories for men and the World Health Organization’s recommendation of 10 percent as the limit. The results showed that participants who consumed between 10 and 25 percent were at a 30 percent increase for cardiovascular disease death and those who consumed 25 percent or more were twice as likely. What tips do you have for patients to minimize added sugar intake?

Vitamin supplements may lower exercise endurance

woman-039s-hand-take-vitamin-omega-3-fish-oil-pills-on-a-hand-100176690In an 11 week trial recently published in The Journal of Physiology, researchers at the Norwegian School of Sport Sciences in Oslo assessed the effect vitamin C and E have on exercise endurance. 54 participants received either 1,000 mg of vitamin C plus 235 mg of vitamin E or placebo and they exercised up to four times a week. Researchers found no difference in performance between the two groups. However, those who took vitamin C and E seemed to produce less of a specific mitochondrial marker in their muscle cells, which suggests of a decrease endurance. What are your thoughts about this study? What are your typical recommendations to patients looking to enhance their exercise endurance?

Antibiotic use in animals linked to bacterial resistance in humans

cow-milking-facility-100193460In an analysis conducted by the Food and Drug Administration on the use of antibiotics in animal feed, scientists found that 18 out of 30 of them may increase the risk of human exposure to antibiotic-resistant bacteria. There was insufficient information for the scientists to review the other 12 antibiotics. Even though the FDA has made efforts to reduce the use of antibiotics in animals, it is still broadly used. What are your thoughts about this article? What are your recommendations to minimize human exposure to antibiotic-resistant bacteria?

Good cholesterol may clog arteries

cholesterol-meter-10069234In a recent study published in Nature Medicine, researchers at the Cleveland Clinic found that high-density lipoprotein (HDL) or “good” cholesterol can become dysfunctional and lose its protective properties. When HDL becomes abnormal, it may enter the bloodstream and clog the arteries. Of the 627 patients in the study, researchers found that those who had higher blood levels of abnormal HDL were at greater risk of heart disease. What are your thoughts about this study?

Soda coloring may be dangerous to your health

colas-100172977Consumer Reports, the World Health Organization’s International Agency for Research on Cancer, and the state of California announce that a chemical known as 4-methylimidazole or 4-Mel found in many soft drinks and foods may be carcinogenic. 4-Mel is labeled simply as “caramel coloring” on U.S. product labels and it gives foods its golden-brown color. The state of California has placed a limit on 4-Mel containing products to 29 micrograms. However, Consumer Reports has found that many products still exceeded the permitted limit and the same products outside of California contained amounts even greater. What is the best way to educate about dangers of consuming foods containing caramel coloring?

Omega-3 fatty acids may reduce brain aging

human-brain-100214120The Women’s Health Initiative Memory Study recently published looked at the association between omega-3 fatty acids and brain aging in 1,111 postmenopausal women who were on average 70 years old. The researchers measured the amounts of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the women’s red blood cells at the beginning of the study and followed them for eight years. It turned out that women with the highest levels of EPA and DHA had a greater brain volume and hippocampus compared to women who had the lowest fatty acid levels. This suggests that EPA and DHA may protect the brain from shrinkage with age. What are your thoughts about this study? How often do patients ask you about using omega-3 fatty acids for treatment or prevention of cognitive disorders?

Mediterranean diet may reduce Peripheral Artery Disease

oil-and-olive-10025527A recent randomized trial published in the Journal of the American Medical Association examined the association between Mediterranean diet and the incidence of symptomatic peripheral artery disease (PAD). Patients were randomly selected to participate in one of the following groups: a Mediterranean diet high in extra-virgin olive oil; a Mediterranean diet high in nuts; or a low-fat diet. The results of the study found that both Mediterranean diet groups had a significantly lower occurrence of PAD compared to the low-fat diet group and no significant difference was found between the two intervention groups. How often do you recommend Mediterranean diet to your patients?

Warning about thyroid supplements

bottle-of-pills-10014449In a recent report published in a scientific journal called Thyroid, researchers found that 9 out of 10 popular thyroid supplements sold online contained prescription medications known as thyroxine (T4) and/or triiodothyronine (T3). Some products contained amounts well over the normal starting dose of these medications. How often do you recommend alternatives to thyroid supplements?
