Fruit provides health benefits that affect the brain. For example, most fruits contain antioxidants, which neutralize toxins that can destroy brain cells. Many fruits also increase blood circulation, which can increase the nutrients and oxygen delivered to the brain. A 2005 study published in "Neurology" found that each additional piece of fruit consumed decreases stroke risk by 11 percent. Researchers believe the mechanism of action is the blood pressure and cholesterol lowering effect of the active compounds found in fruit.
Cherries
Cherries have a low glycemic index, which means they contain low levels of sugar compared with other fruits. Fruits that contain high levels of sugar spike an insulin reaction when consumed, which causes the sugar to quickly vacate the blood. Blood sugar highs and lows create high mental energy followed quickly by brain fatigue. In contrast, fruits like cherries with low sugar content, maintain a steady level of energy that helps sustain mental function, according to website AskDrSears.com.
