Alpha-Carotene

Alpha-carotene is part of the carotenoid family, and is one of the most abundant carotenoids in a healthy diet. It is a "provitamin A" compound which means that body can convert it into vitamin A (retinol) for the maintenance of healthy skin and bones, good vision, and a robust immune system. As a provitamin A, alpha-carotene is only about half as effective as beta-carotene.

In recent years, carotenoids including alpha-carotene have received a tremendous amount of attention as potential anti-cancer and anti-aging compounds. Alpha-carotene is a powerful antioxidant, protecting the cells of the body from damage caused by free radicals. Alpha-carotene contains flavonoids, which are antioxidant substances that give color and flavor to many orange- and red-colored fruits and vegetables.

In addition, alpha-carotene may help prevent cancer by stimulating cell-to-cell communication, a process which is necessary to ensure proper cell division. Researchers now believe that poor communication between cells may be one of the causes of the overgrowth of cells, a condition which eventually leads to cancer.

Food sources of alpha-carotene include carrots, sweet potatoes, squash, spinach, tomatoes, green beans, kiwi, cantaloupe, mangos and brussels. To maximize the availability of the carotenoids in the foods listed above, the foods should be eaten raw or steamed lightly.
