Cognitive Health Among Elderly Linked To Diet Rich In Fruits And Vegetables

June 16, 2010: 11:38 PM EST
Scientists who studied the diets of 2,031 elderly Norwegian men and women (aged 70–74 years) and performed extensive cognitive test found that those who consumed the highest levels of fruits and vegetables not only had a reduced risk of cardiovascular disease and cancer, they had better cognitive health. According to the researchers, not all plant foods showed equally positive associations with cognitive performance. “Certain items (mainly carrots, cruciferous vegetables, citrus fruits and high-fiber bread) are the most valuable choices,” they said, noting that combining fruits and vegetables offered the highest association with cognitive health. They also said the only negative association for cognitive health was found in white bread.
