Numerous studies worldwide, including some sponsored by the National Cancer Institute, confirms that people who eat diets high in carrots and other foods rich in carotene are less likely to develop certain forms of cancer than those who don't. In fact, studies show that even people who are exposed to specific carcinogens such as tobacco and ultraviolet light could reduce their risk of cancer by eating more carotene.
Carotene is also excellent for the eyes.
Carotene permits the formation of visual purple in the eyes, which helps counteract night blindness and weak vision. Three large raw carrots a day may also lower blood cholesterol levels, thus reducing your risk of developing coronary artery diseases, the leading cause of heart attack. Carrots are also a good treatment for diarrhea, and can relieve gas and heartburn. Some possible benefits of carrots are that they promote eye health, help prevent cancer, lower cholesterol, soothe indigestion, and can help relieve diarrhea. Carrots can be consumed orally in both juice and soup.
