Folic acid may be the most important nutrient to reduce Alzheimer's risk

From Life Extension Foundation...08-11-05

The results of a long-term study published in the inaugural issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association, indicate that consuming adequate levels of the B vitamin folate is associated with the greatest protection against Alzheimer's disease of any nutrient examined. Folate is found in a number of foods, such as leafy green vegetables, but is often destroyed by cooking. Grain products have been fortified with folic acid in the United States since 1998, however, it is believed that many Americans are still deficient in the vitamin. The study is the largest so far to evaluate the association between folate and Alzheimer's risk and to analyze antioxidants and B vitamins at the same time.
Assistant professor of neurology Maria Corrada of the University of California Irvine's Institute for Brain Aging and Dementia and colleagues utilized data from the Baltimore Longitudinal Study of Aging which was begun in 1958 and includes over 1,400 participants. The current study involved 579 subjects without dementia aged 60 and older who completed seven-day dietary diaries between 1984 and 1991. Fifty-seven of these participants developed Alzheimer's disease.
The researchers found that individuals whose intake of folate, vitamin B6 and vitamin E were higher had a lower risk of developing Alzheimer's disease than those whose intake was less, however when the vitamins were analyzed together, only folate intake was correlated with a significantly decreased risk of the disease. Dr Corrada noted, "The participants who had intakes at or above the 400 microgram recommended dietary allowance of folates had a 55 percent reduction in risk of developing Alzheimer's. But most people who reached that level did so by taking folic acid supplements, which suggests that many people do not get the recommended amounts of folates in their diets."


Comment: Make sure your multi vitamin has at least 400 mcgs of Folic acid. If it doesn't, change brands or add extra B-Complex. Other studies indicate Vit E and C as well as Omega 3 EFA's are also critical here.
