Grapefruit

From Wikipedia, the free encyclopedia

 
This article is about the citrus fruit. For the Sixties pop band, see Grapefruit (band)

The grapefruit is a sub-tropical citrus tree grown for its fruit which was originally named the "forbidden fruit" of Barbados.[1]

These evergreen trees are usually found at around 5-6 m tall, although they can reach 13-15 m. The leaves are dark green, long (up to 150 mm) and thin. It produces 5 cm white four-petalled flowers. The fruit is yellow-skinned, largely oblate and ranges in diameter from 10-15 cm and has an acidic yellow segmented pulp. The numerous cultivars include the white grapefruit and the red, of which the 1929 US Ruby Red (of the Redblush variety) has a patent. The fruit has only become popular from the late 19th century; before that it was only grown as an ornamental plant. The US quickly became a major producer of the fruit, with orchards in Florida and Texas. In Spanish, the fruit is known as toronja or pomelo.

History

The fruit was first documented in 1750 by Rev. Griffith Hughes describing specimens from Barbados.[2] Currently, the grapefruit is said to be one of the "Seven Wonders of Barbados".[3] It had developed as a hybrid of the pomelo (Citrus maxima) with the sweet orange (Citrus sinensis), though it is closer to the former. It was brought to Florida by Odette Philippe in 1823. Further crosses have produced the tangelo (1905), the minneola (1931) and the sweetie (1984).

The grapefruit was known as the shaddock or shattuck until the 1800s. Its current name alludes to clusters of the fruit on the tree, which often appear similar to grapes. Botanically, it was not distinguished from the pomelo until the 1830s, when it was given the name Citrus paradisi. Its true origins were not determined until the 1940s. This led to the official name being altered to Citrus × paradisi.

Colors and flavors

Grapefruit comes in many varieties, determinable by color, which is caused by the pigmentation of the fruit in respect of both its state of ripeness and genetic bent.

The most popular varieties cultivated today are red, white, and pink hues. The family of flavors range from highly acidic to sweet-tart, offering something different for everyone.

Interactions with drugs

Grapefruit can have a number of interactions with drugs, often increasing the effective potency of compounds. Grapefruit contains naringin and bergamottin, which inhibit the cytochrome P450 isoform CYP3A4 in the liver. It is via inhibition of this enzyme that grapefruit increases the effects of buspirone (Buspar), caffeine, several statin drugs (such as simvastatin), terfenadine, felodipine, nifedipine, verapamil, estradiol, tacrolimus, dextromethorphan (significant only at recreational doses), benzodiazepines, and ciclosporin.[4] Hence, this effect was only discovered after being responsible for a number of deaths due to overdosing on medication.

Medicinal effects

There is evidence that citrus grapefruit seeds have low levels of antioxidant properties.[5]

Grapefruit forms a core part of the "grapefruit diet", the theory being that the fruit's low glycemic index is able to help the body's metabolism burn fat.

Grapefruit peel oil is used in aromatherapy and it is historically known for its aromatic scent.

Grapefruit pectin is a beneficial source of soluble fiber as part of a well balanced, healthy diet.

Grapefruit seed extract has been claimed to be a strong antimicrobial with proven activity against bacteria and fungi. However, studies have shown the efficacy of grapefruit seed extract as an antimicrobial is not demonstrated. Although GSE is promoted as a highly effective plant-based preservative by some natural personal care manufacturers, studies indicate the universal antimicrobial activity associated with GSE preparations is merely due to contamination with synthetic preservatives.[6][7][8][9][10]
