Twenty years ago, Congress passed the Dietary Supplement Health and Education Act (DSHEA), recognizing the role of dietary supplements in health promotion and prevention of chronic diseases. The law established a new regulatory framework and mechanisms to deal with safety issues, labeling, and health claims. It provided guidance on good manufacturing practices. Unfortunately, Congress didn’t guarantee funding for enforcement of DSHEA.
Not everyone is intrigued by science. I get that. However, science (and scientists) is interesting. Three reasons to follow science blogs: 1) By nature, scientists test hypotheses. When considering questions from different perspectives, they challenge the status quo. 2) Scientists have a profound ability to distill a problem into the obvious. And 3), being a scientist can be fun. We may even have friends.
Two new reviews were published this week. Barnes and colleagues review nutrients with a role in maintaining cognitive function. Whitehead and colleagues conducted a meta-analysis of randomized, placebo-controlled studies (RCTs) using ≥ 3 g oat beta glucan daily.
Both reviews focus on nutrient intakes required to optimize health.
Experts from the European Food Safety Authority (EFSA) published a scientific opinion that a cause and effect relationship has been established between the consumption of docosahexaenoic acid (DHA) and contribution to normal brain development. The Panel noted the well-established role of DHA in normal brain function across all ages, including brain development in infants and children.
Based on the scientific evidence, the Panel approved the following statement:
Iodine deficiency is one of the top three micronutrient deficiencies that are targeted by the World Health Organization. Shocking statistics estimate that 18 million infants are mentally impaired each year due to frank iodine deficiency. Another report shows that iodine deficiency is relatively common even in well-nourished populations. Why aren't we doing more to solve this problem?
Humans can synthesize vitamin D when skin is exposed to strong sunlight. Obviously, babies are dependent upon their mother for vitamin D until birth (in utero). Even after birth, depending upon seasonal temperatures, a baby may be bundled in wraps and kept inside. Thus, the vitamin D status of an infant is totally dependent upon his/her mother.
Zhang and colleagues examined the nutritional requirements for vitamin D in 30 women during pregnancy.
It seems like the only health-related news these days deals with the recent cases of Ebola that have appeared in Texas. In many ways, the Ebola situation in Africa draws parallels to the malnutrition crisis observed in developing nations, where millions are affected by deficiencies of essential nutrients such as vitamin A, iron, and iodine. But if we in the Western world are hardly impacted to the same degree by either Ebola or malnutrition, why should we feel compelled to help?
Experts from the European Food Safety Authority (EFSA) published a scientific opinion that supplemental DHA and EPA from algal oil sources (Schizochytrium species) can be safely increased from 3 grams daily to 5 grams daily as there is no safety concerns for adults.
