Bell peppers (Capsicum annuum) are fruits that belong to the nightshade family. They are related to chili peppers, tomatoes, and breadfruit, all of which are native to Central and South America. Also called sweet peppers or capsicums, bell peppers can be eaten either raw or cooked. Like their close relatives, chili peppers, bell peppers are sometimes dried and powdered. In that case, they are referred to as paprika. They are low in calories and exceptionally rich in vitamin C and other antioxidants, making them an excellent addition to a healthy diet.
