Reduced risk of Alzheimer’s disease with high folate intake: The Baltimore Longitudinal Study of Aging
This study reviewed the diets of over 500 individuals over the age of 65. They found a significant correlation with individuals who met or exceeded the RDA intake for folate and a decreased risk for Alzheimer’s. Interestingly, only 13% of the sample size were able to meet RDA levels with diet alone!
The best source of folate for us is in its natural form:
Because we continue to learn how vitamins work in symphony with other micronutrients, our best practice is to get essential vitamins from foods rather than isolated in synthetic supplements. Furthermore, added folate to food products, like bread, present similar problems, by taking the nutrient out of its natural environment, whereby we may unknowingly decrease its effect on us, as well as our ability to absorb it.
