"Citrus paradisi" most commonly known as grapefruit is a real miracle fruit. Grapefruits can be white, yellow, pink or red in color with a taste ranging from sour to sweet. The calories in grapefruit are very low, but the flavor and nutrients are high. Just a half grapefruit each day can ensure the average adult is meeting at least half of typical vitamin C requirements, one of the reasons why grapefruit benefits many areas of health.
Grapefruit also contains health-promoting phytochemicals like lycopene and beta-carotene (in the pink and red varieties) as well as limonoids like limonin and flavonoids like naringenin.
