Beta-carotene is a yellowish compound found in most yellow, orange and dark green vegetables, and converted in the body to Vitamin A. Vitamin A can be toxic but Beta Carotene is not. Beta-carotene is a safe precursor of vitamin A. Human intestinal enzymes convert dietary beta-carotene into active vitamin A. 1mg. of beta-carotene provides 1,667 I.U. of vitamin A activity. Beta-carotene not converted to vitamin A is absorbed intact and has other functions in the body. They protect cells from free radical damage which are unstable chemicals formed in the body during metabolism and from exposure to environmental sources such as pollution and cigarette smoke. Free radicals ARE necessary for energy metabolism and immune function, but when an excessive number of free radicals are formed, they can attack healthy cells, especially their membrane lipids and proteins. This, in turn, is thought to contribute to a number of degenerative diseases. Numerous studies have demonstrated the importance of beta-carotene for normal immune function. The immune benefits are due to its vitamin A precursor role and its antioxidant function. The U.S. Department of Agriculture and the National Cancer Institute recommend an intake of 5mg. (8,335 I.U.) or more of beta-carotene. Unfortunately, most diets provide only 1-2mg. (1,667-3,334 I.U.) per day.
