Grapefruit (Citrus × paradisi)

Grapefruit (IPA: /ˈɡreɪpˌfruːt/) is a subtropical citrus tree known for its relatively large sour to semi-sweet, somewhat bitter fruit.

Etymology

The name "grapefruit" is attributed to the fruits growing in clusters which resemble those of grapes. The term was first used in 1814 in Jamaica.

Description

Grapefruit trees usually grow to around 5–6 meters (16–20 ft) tall, although they can reach 13–15 m (43–49 ft). The leaves are dark green, long (up to 15 centimeters, or 5.9 inches) and thin. It produces 5 cm (2 in) white four-petaled flowers. The fruit is yellow-orange skinned and largely an oblate spheroid; it ranges in diameter from 10–15 cm (3.9–5.9 in). The flesh is segmented and acidic, varying in color depending on the cultivars, which include white, pink, and red pulps of varying sweetness.

Cultivation

The grapefruit was brought to Florida by Count Odet Philippe in 1823, in what is now known as Safety Harbor. Further crosses have produced the tangelo (1905), the Minneola tangelo (1931), and the oroblanco (1984).

Health Benefits and Risks

Grapefruit and its juice have a number of health benefits. It is a good source of vitamin C and contains the fiber pectin, and the pink and red hues contain the beneficial antioxidant lycopene. Studies have shown that grapefruit helps lower cholesterol, and there is evidence that the seeds have antioxidant properties. However, grapefruit can interact with prescription drugs, leading to potentially severe health consequences.
