Some people believe that healthy foods are tasteless and boring, but nothing could be further from the truth. The next time you’re craving something tasty, opt for grapefruit. Grapefruits are sour fruits full of health-inducing vitamins and minerals. The flavonoids in grapefruits can help protect against some cancers, inflammation, and obesity. Try adding grapefruit slices to a fruit salad, or squeeze the juice into water to make a drink.
