The vitamins and minerals are in the news again, with all this being related to their addition to sports drinks, water and juices. Scientists suggests that consumers might be ingesting higher than necessary (and sometimes potentially harmful) amounts. When consumed in excess, water-soluble vitamins like B and C are in the urine, but fat soluble-vitamins including A, D, E and K, accumulate in tissues, posing potential risks. Some people (for example, pregnant or lactating women) will require additional vitamins and minerals, but for the majority of the population, these nutrients should be primarily acquired through daily diet. This discussion extends to antioxidants and the lack of information on the long-term supplementation effects. Scientists state that it is impossible to consume too much from foods but the exposure through supplementation may be too great. How do you counsel your patients about healthy diet and vitamin/mineral/antioxidant rich foods? For those who require supplementation, what are your typical recommendations?
Based on a new study published in the journal Cell Reports, the biological response to high-fat diet in male and female brains are not the same. According to the study, the brains of male mice became inflamed and their heart were damaged after given a steady high-fat meals, while nothing of that happened to the female mice. Interestingly, female brains have been found to produce anti-inflammatory chemicals that kept them from getting harmed by high-fat diet. However, further studies are still needed to prove these results on humans. How much do your dietary recommendations vary in men and women? What are your thoughts about this research?

According to a new study published in the American Journal of Public Health, drinking sodas has been found to be linked to a fast aging process. By analyzing stored DNA from more than 5,300 healthy Americans in the National Health and Nutrition Examination Survey (NHANES) from some 14 years ago, researchers have revealed that drinking a 20-ounce bubbly beverage every day is linked to 4.6 years of additional aging. Interestingly, these results are similar to those that are linked to smoking. However, the cause-effect relationship has not been established yet. The studies regarding to the danger of sodas are continuously growing, what are your thoughts about the best way to decrease their consumption?

Gestational diabetes, a common pregnancy complication, has been found to be possibly related to eating fried foods on a regular basis. The research published in the journal Diabetologia discovered 13% increase in gestational diabetes among pregnant women who eat fried foods one to three times per week comparing to ones who eat once a week. The percentage escalates to 31% and more than 50% for those who eat four to six times and seven or more times per week, respectively. However, the cause-effect relationship has not been yet established in this study, and more evidence is needed. How do you typically counsel your pregnant patients about healthy nutrition? What are some of the recommendations that you make?

A 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?

In 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?

Consumer 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?

A 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?
