High dietary folate may decrease the incidence of stroke, according to a 20-year study reported in a recent edition of Stroke: Journal of the American Heart Association. Researchers found that people who consumed at least 300 micrograms (mcg) of folate per day had a 20% lower risk of stroke and a 13% lower risk of cardiovascular disease than those consuming less than 136 mcg of folate per day. The findings accounted for other heart disease risk factors such as cholesterol, blood pressure, smoking and obesity.
