Researchers report that an increased intake of folate, from both diet and supplements, may halve the risk of developing Alzheimer's disease.
Researchers analyzed the diets of over 960 participants, recording intakes of folate, vitamin B6 and B12.
After a six year follow up period, researchers found that the highest intake of folate from diet and supplements was associated with a significant reduction in Alzheimer's risk.
The protective effect seems to be a result of a combination of dietary folate and supplements, since a protective effect was not seen for just dietary intake or supplement intake.
Food sources of folate include green leafy vegetables, including spinach and turnip greens. Other sources include dried beans and peas and sunflower seeds, lentils, asparagus and avocado.
