"Easy to find and portable, blueberries are a great low-calorie summer snack," says Erika Horowitz, RDN. One cup of these brightly colored berries contains just 84 calories, as well as fiber, vitamins K and C, and cancer-fighting anthocyanins. Also good: Research indicates that, like cranberries, blueberries have compounds that prevent bacteria from sticking to walls of the bladder, helping to prevent urinary tract infections. To incorporate this powerhouse fruit into your diet try Greek yogurt with chocolate, walnuts and blueberries as a healthy and easy snack.
