Shaddock

Shaddock is a citrus fruit commonly known as grapefruit. The name shaddock derives from Captain Shaddock, who reputedly introduced the fruit to Jamaica from Barbados in the 18th century, after which the fruit spread to other Caribbean islands and beyond. The fruit is a hybrid, Citrus × paradisi, generally considered a cross between the pomelo (Citrus maxima) and the sweet orange (Citrus × sinensis). The name grapefruit refers to the way the fruit grows in clusters, resembling grapes.

Description: Grapefruit fruits are large, with a thick rind that is yellow, pale orange, or reddish, depending on cultivar and sun exposure. The flesh is typically segmented and can be white, pink, or red; pink and red-fleshed varieties are commonly sweeter and more aromatic. The fruit is notable for its acidity, bitterness, and sweetness. Many varieties are seedless.

Cultivation and distribution: Grapefruit is cultivated in subtropical and tropical climates; major producers include the United States (notably Florida and Texas), Mexico, Israel, South Africa, Spain, and parts of the Caribbean. It requires well-drained soil and full sun.

Uses and nutrition: Grapefruit is eaten fresh and used for juice; it is a good source of vitamin C and other nutrients. Some varieties are used in cooking and cocktails. Caution: grapefruit contains furanocoumarins that can interact with certain medications by inhibiting intestinal cytochrome P450 3A4, potentially causing adverse effects. People taking prescription drugs should consult healthcare providers about grapefruit consumption.
