Green vegetables might hold clue to Alzheimer's
Deficiencies in the levels of folate in the blood can triple a person's risk of developing Alzheimer's and other forms of dementia, according to researchers. Folate, which is also known as vitamin B9, is found in most dark green vegetables.
The study focused on 518 senior citizens in South Korea between 2001 and 2003. Tests for dementia were conducted at the start and end of the two-year period, and blood tests were taken periodically to assess the levels of folate in the blood.
