Grapefruits were discovered in the West Indies and imported to the state of Florida in the 19th century. The name refers to the appearance of the fruits as they grow on trees in clusters - similar to grapes.
Grapefruits are rich in vitamin C and are also a good source of potassium and vitamin A. One-half of a grapefruit has 37 calories. Serve your grapefruit with a little sweetener as a nice addition to breakfast, or make a Grapefruit Sunrise Smoothie
