Nutritious and delicious, blueberries contain high amounts of vitamins, minerals and dietary fiber, and are one of the richest dietary sources of antioxidant polyphenols. A half-cup serving of ripe wild blueberries (approx. 150 pieces) can provide 200 to 400 milligrams (mg) of polyphenols.

Polyphenols refer to a group of active compounds found naturally in plants, particularly those with vibrant hues. They are extensively studied for their beneficial properties, which include antioxidant, anti-inflammatory, anticancer and anti-diabetic activities.

According to a new study published in the American Journal of Clinical Nutrition (AJCN), the polyphenols in wild blueberries can also boost brain function and help maintain a healthy heart.
