The grapefruit (Citrus × paradise– the “x” stands for hybrid) is a subtropical citrus tree known for its tart and tangy taste, with an underlying sweetness. Grapefruits are related to the orange, lemon and pomelo, have either yellow or pinkish-yellow skin and categorized as white (blond), pink or ruby, based on the color of their flesh. The wonderful flavor of a grapefruit is like paradise as is expressed by its Latin name, Citrus paradise.

Grapefruits have a rather recent history, having been discovered in Barbados in the 18th century, and named “forbidden fruit”. Many botanists believe the grapefruit is actually the result of a natural cross breeding between the orange and the pomelo, a citrus fruit that was brought from Indonesia to Barbados in the 17th century. In 1814, people in Jamaica named it “ grapefruit” due to its fruit arrangement resembling the way grapes grew in clusters.


Grapefruit trees were planted in Florida in the early 19th century, although they did not become a viable commercial crop until later that century. Florida is still a major producer of grapefruits, as is California, Arizona and Texas. Other countries that produce grapefruits commercially include Israel, South Africa and Brazil.

Side effects:

The only known side effect, though a lethal one, is the fruit’s impact when taken with some commonly used cancer, heart, cholesterol and painkilling drugs.


Compounds in grapefruit juice, including naringenin, slow the normal detoxification and metabolism processes in the intestines and liver, which hinders the body’s ability to breakdown and eliminate some pharmaceutical drugs. Grapefruit may increase the effects of calcium channel blockers, statins (leading to Rhaddomyolysis), benzodiazepines, immunosuppressants, and HMG-CoA reductase inhibitors.

Just one glass of grapefruit juice is enough to treble the potency of these medicines. So consult your GP before drinking the juice.
