It's great to juice carrots because it has been shown that the nutrients in them are more bio-available when juiced, as opposed to eating them. Carrots are full of vitamin A and have the highest source of vitamin A. The vitamin A is found in the pigment beta-carotene, which gives the carrots their strong orange colour. The body will convert beta-carotene into vitamin A. It has been said that carrots are known to be the 'anti-cancer kings' of the vegetable world, this is because the beta-carotene can disintegrate the mucous membrane around cancer cells. This pigment is also very beneficial for the heart, as it protects the cardiovascular system, as it helps to reduce ruptures and injury in the blood vessels that coud lead to blood clots.
