Carrots are one of the most popular, versatile vegetables in the world. Botanically known as Daucus carota (Fam: Apeaceae), it is called karaz in Hausa, kaooti in Yoruba and karot in Igbo. There are white, yellow, orange, purple and red varieties of carrot, although the orange carrots are the ones commonly seen in this clime.

Constituents

Carrots are rich in vitamins, minerals, and fibre.  The vitamins include B1, B2, B6, K and C, niacin, folic acid, pantothenic acid, iron, copper, phosphorus, manganese and potassium. Some important antioxidants in carrots include carotenoids, such as alpha- and beta-carotene and lutein, cyanidins, poly-acetylenes like falcarinol and falcarindiol, lycopene, coumaric acid and caffeic acid, to mention a few. The carotene accounts for the bright orange colour of orange carrots.

Pharmacological actions and medicinal uses

The health benefits of carrot can be largely due to its rich beta carotene and fibre content. Recent studies have revealed that carrots may play an important role in reducing the incidence of cancers of the prostate, breast, lungs and colon. This anti-cancer effect is largely attributable to phytonutrients found in carrots such as beta carotene, falcarinol and falcarindiol which possess excellent antioxidant properties and help to mop up free radicals.

Beta carotene consumed through carrots is first converted to vitamin A in the liver. Subsequently, vitamin A is then converted to rhodopsin, an important pigment for night vision. More still, beta carotene has also been shown to offer protection against senile cataracts and macular degeneration which are important causes of blindness.

The potassium and coumarin contents of carrot are responsible for its cardioprotective and blood pressure lowering effect.

The carotenoids which are found in carrots tend to prevent insulin resistance. In diabetic individuals, carrots enhance insulin function and glucose metabolism which helps to stabilise blood glucose. The high fibre content of carrots adds bulk to the diet, thus stimulating peristalsis and enhancing onward propulsion of food in the intestine. This helps to prevent constipation and protects the gut from toxic substances that may lead to colon cancer.
