Bananas are among the most widely consumed fruits on the planet and, according to the U.S. Department of Agriculture, Americans' favorite fresh fruit.The curvy yellow fruits are high in "potassium and pectin, a form of fiber," said Laura Flores, a San Diego-based nutritionist. They can also be a good way to get magnesium and vitamins C and B6. "Bananas are high in antioxidants, which can provide protection from free radicals, which we come into contact with every day, from the sunlight to the lotion you put on your skin," Flores added.
