Foods High in Folate
Doctors have known for years that deficiency of certain B vitamins, particularly folate, can make it difficult to perform some cognitive tasks. New evidence shows that even slightly low levels can have a similar effect because folate, along with vitamins B6 and B12, helps to keep homocysteine levels in check. This amino acid impairs brain function and can dramatically increase a person’s risk of Alzheimer’s disease (as well as heart disease). The good news is that folate from foods like dark leafy greens and dried beans may slow cognitive decline.
