History

The wild ancestors of the carrot are likely to have come from Afghanistan, which remains the centre of diversity of D. carota, the wild carrot. Selective breeding over the centuries of a naturally occurring subspecies of the wild carrot, Daucus carota subsp. sativus reducing bitterness, increasing sweetness

and minimizing the woody core, has produced the familiar garden vegetable.

In early use, carrots were grown for their aromatic leaves and seeds, not their roots. Some relatives of the carrot are still grown for these, such as parsley, fennel, dill and cumin. The first mention of the root in classical sources is in the 1st century CE. The modern carrot appears to have been introduced to Europe in the 8-10th centuries.[citation needed] The 12th c. Arab Andalusian agriculturist, Ibn al-'Awwam, describes both red and yellow carrots; Simeon Seth also mentions both colours in the 11th century. Orange-coloured carrots appeared in the Netherlands in the 17th century. These, the modern carrots, were intended by the antiquary John Aubrey (1626-1697) when he noted in his memoranda "Carrots were first sown at Beckington in Somersetshire Some very old Man there [in 1668] did remember their first bringing hither."

In addition to wild carrot, these alternative (mostly historical) names are recorded for Daucus carota: Bee's-nest, Bee's-nest plant, Bird's-nest, Bird's-nest plant, Bird's-nest root, Carota, Carotte (French), Carrot, Common carrot, Crow's-nest, Daucon, Dawke, Devil's-plague, Fiddle, Gallicam, Garden carrot, Gelbe Rübe (German), Gingidium, Hill-trot, Laceflower, Mirrot, Möhre (German), Parsnip (misapplied), Queen Anne's lace, Rantipole, Staphylinos, and Zanahoria.

Uses

Carrots can be eaten in a variety of ways. Only 3% of the β-carotene in raw carrots is released during digestion: this can be improved to 39% by pulping, cooking and adding cooking oil.[2] Alternatively they may be chopped and boiled, fried or steamed, and cooked in soups and stews, as well as baby and pet foods. A well known dish is carrots julienne. Grated carrots are used in carrot cakes, as well as carrot puddings, an old E

nglish dish thought to have originated in the early 1800s. The greens are edible as a leaf vegetable, but are rarely eaten by humans. Together with onion and celery, carrots are one of the primary vegetables used in a mirepoix to make various broths.

In India carrots are used in a variety of ways, as salads or as vegetables added to spicy rice or daal dishes, and the most popular variation i

n north India is the Gaajar Kaa Halwaa carrot dessert, which has carrots grated and cooked in milk until the whole thing is solid, after which nuts and butter are added. Carrot salads are usually made with grated carrots in western parts with a seasoning of mustard seeds and green chillies popped in hot oil, while adding carrots to rice usually is in julienne shape.

The variety of carrot found in north India is

rare everywhere except in Central Asia and other contiguous regions, and is now growing in popularity in larger cosmopolitan cities in South India. The north Indian carrot is pink-red comparable to plum or raspberry or deep red apple in colour (without a touch of yellow or blue) while most other carrot varieties in world are from orange to yellow in colour, comparable to hallowe'en pumpkins.

Ever since the late 1980s, baby carrots

or mini-carrots (carrots that have been peeled and cut into uniform cylinders) have been a popular ready-to-eat snack food available in many supermarkets.

Carrot juice is also widely marketed, especially as a health drink, either stand-alone or blended with fruits and other vegetables.

Nutrition

The carrot gets its characteristic and bright orange colour from β-carotene, which is metabolised into vitamin A in humans when bile salts are present in the intestines.Massive overconsumption of carrots can caus

e caroteno

sis, a benign condition in which the skin turns orange. Carrots are also rich in dietary fibre, antioxidants, and minerals.

Lack of Vitamin A can cause poor vision, including night vision, and vision can be restored by adding Vitamin A back into the diet. An urban legend says eating large amounts of carrots will allow one to see in the dark. The legend d

eveloped from stories of British gunners in World War II who were able to shoot down German planes in the darkness of night. The legend arose during the Battle of Britain when the RAF circulated a story about their pilots' carrot consumption as an attempt to cover up the di

scovery and effective use of radar technologies in engaging enemy planes, as well as the use of red light (which does not destroy night vision) in aircraft instruments. It reinforced existing German folklore and helped to encourage Britons—looking to improve their night vision during the blackouts—to grow and eat the vegetable.

Ethnomedically, the roots are used to treat digestive problems, intestinal parasites, and tonsillitis or constipation.
