Peanuts (Arachis hypogaea) have a high content of niacin and folate and are an excellent source of vitamin E. These nutrients have shown to protect against Alzheimer’s disease and age-related decline in cognitive abilities. In almost 4,000 people who were 65 years or older, niacin from food slowed the rate of cognitive decline.
Peanuts also contain fair amounts of a polyphenolic compound called resveratrol. It stimulates the biogenesis of mitochondria in the cells. This is beneficial to highly active and energy-consuming cells like the brain cells.
Eating peanuts can boost resveratrol levels in the body, thereby treating neurodegenerative and neuroinflammatory diseases.
