Grapefruit is a subtropical citrus fruit and tree, scientifically known as *Citrus × paradisi*. It is a hybrid of pomelo and sweet orange, typically larger than an orange, with a flavour ranging from sour to semi-sweet and often bitter.

What it is

Grapefruit grows on trees in warm, subtropical climates and produces a fruit about 10–15 cm in diameter. The thick rind encloses segmented flesh that can be white, pink, or red. The name comes from the fruit's clustered growth pattern, which resembles grapes.

Why it matters

Grapefruit is a notable source of vitamin C and fibre, and it also provides vitamin A, folate, potassium, and plant compounds like flavonoids and lycopene in some varieties. In Canada, it is widely available as an imported citrus fruit, but readers should note that grapefruit can interact with some prescription drugs.

Key details

The fruit is commonly eaten fresh, but also used in salads, yoghurt, and other dishes. Major commercial producers include the United States (especially Florida, Texas, Arizona, and California) and China. The early history of grapefruit is often placed in the Caribbean, particularly Barbados and the West Indies.
