NUTRITION INVESTIGATOR INTERPRETATION - Half the US takes supplements. Even so, most need more vitamin D, antioxidants, and DHA, one of two essential fatty acids in fish oil. "Tens of millions of new Alzheimer's disease (AD) and other dementia cases are projected as elderly populations increase around the world." A DHA/antioxidant/vitamin D supplement could dramatically decrease how many will suffer (see articles 1-5 below).

SUMMARY - 1. Half of the US takes supplements. Teenage girls and men and women over 71 are the most deficient in vitamin D - A total of 53% of the U.S. population reported using any dietary supplement (2003–2006), 43% used calcium (2003–2006), and 37% used vitamin D (2005–2006). For total vitamin D intake, males and females over 71, and females ages 14–18 y had the lowest prevalence of meeting the AI. Dietary supplement use is associated with higher prevalence of groups meeting the AI for calcium and vitamin D.

DHA 2. A plausible mechanism by which DHA prevents recurrent affective disorders like depression3. DHA may prevent age-related dementia 4. DHA intake is associated with healthy brains - Five major dimensions of cognitive functioning were assessed with tests of nonverbal reasoning and mental flexibility, working memory, and vocabulary. 5. DHA protects against brain and eye degeneration

WEIGHT CONTROL 6. High fiber diet reduces hunger - Dietary fiber and protein are essential constituents of a healthy diet and are well known for their high satiety impact.

OTHER IMPORTANT NUTRIENTS 7. Magnesium may decrease the risk of colorectal cancer 8. High iron levels are associated with plaque in your arteries - For every 10-µg/L increase in serum ferritin, the risk for atherosclerosis increased by 3%.

POLICY 9. The government poverty food plan is not effective
