Blueberries and other blue-, black- or purple-skinned foods are very important for brain health and protecting cells from too much stress. These foods are packed with phytonutrients that include resveratrol and pterostilbene.

Resveratrol is a popular purple phytonutrient that promotes healthy aging processes by reducing inflammation and blood sugar, along with being beneficial for the cardiovascular system. Food sources of resveratrol include grapes and grape-derived products.

Pterostilbene is a phytonutrient that resembles resveratrol and is found in blueberries and grapes. There is some animal research that suggests it wards off cancer, keeps cholesterol low and may help with preserving cognition.

So fill your smoothies with frozen blueberries or pack them for a sweet snack. Your brain will thank you.
