Blueberries Boost Cognition

Blueberries have high levels of phenolic compounds and antioxidants, which can benefit cognition. In a trial with 38 older adults, scientists sought to determine if eating a reasonable number of the berries daily could elevate these levels enough to improve cognition. They found that after 90 days of eating 24 grams of dried or 1 cup of fresh fruit per day, the group demonstrated improved cognitive performance and the levels of spotlighted chemicals were increased in the blood.
