Blueberries, an Antioxidant Superfood
Packed with antioxidants and phytoflavinoids, these berries are also high in potassium and vitamin C, making them the top choice of doctors and nutritionists. Not only can they lower your risk of heart disease and cancer, they are also anti-inflammatory.
“Inflammation is a key driver of all chronic diseases, so blueberries have a host of benefits,” says Ann Kulze, MD, of Charleston, S.C., author of Dr. Ann’s 10 Step Diet: A Simple Plan for Permanent Weight Loss and Lifelong Vitality. When selecting berries, note that the darker they are, the more antioxidants they have. “I tell everyone to have a serving (about 1/2 cup) every day,” Kulze says. “Frozen are just as good as fresh.” Be sure to include lots of other fruits and vegetables in your diet as well. Remember too that, in general, the more color they have, the more antioxidants.
