They sound like something a Powerpuff Girl would munch for energy, but these trendy dried wolfberries possess powerful antioxidant capabilities, much like their Plain Jane blueberry, cranberry and cherry counterparts. Goji berries (pronounced "Go-gee") are especially rich in Vitamin A, which promotes healthy vision, and have been used in China for centuries to treat numerous diseases and promote longevity. "Foods high in antioxidants may slow the aging process by minimizing free radical damage that injures cells and DNA," explains Registered Dietitian Jennifer Ventrelle, lifestyle program coordinator at Rush University Prevention Center in Chicago. Goji berries look like red raisins and have a mild, tangy taste. Sample them in a homemade trail mix alongside almonds, dried apricots, sunflower seeds and dark chocolate nibbles.
