Very! Fresh pineapples are about as delicious as they are nutritious. They are sodium-free, fat-free, and cholesterol-free. Additionally, they only have about 30 calories per ½ inch slice, or 80 calories per 1 cup serving of cut fruit. Not only that, but they’re rich in vitamin C, which protects you from heart disease, cancer, and cataracts; as well as manganese, which helps keep bones strong. They’re also high in fiber and contain Bromelain, an enzyme that helps digest protein. Pineapples are great!
