TYPES OF GRAPEFRUITS
Red grapefruit also known as Ruby grapefruit has a deep red flesh and juice. It is rich in lycopene (a powerful cancer-fighting phytonutrient) and beta-carotene. Red Grapefruits are sweeter than the white grapefruits.
The traditional white grapefruit is sometimes called yellow grapefruits. The flesh is light yellow and the juice is almost colorless. The juice is slightly tangy and the flesh firm in texture.
Pink grapefruit is light yellow with a pink tinge. It is high in lycopene and beta-carotene. It has a balanced sweet and tangy taste and the flesh is usually very juicy.
