In addition to their high capsaicin content, cayenne peppers are also an excellent source of vitamin A, through its concentration of pro-vitamin A carotenoids including beta-carotene. Beta-carotene is not only a potent antioxidant in its own right, but can be converted in the body to vitamin A, a nutrient essential for the health of all epithelial tissues (the tissues that line all body cavities including the respiratory, gastrointestinal and reproductive tracts). Beta-carotene may therefore be helpful in reducing the symptoms of asthma, osteoarthritis, and rheumatoid arthritis. In addition, its antioxidant activity make it useful in preventing the free radical damage that can lead to atherosclerosis, colon cancer, and diabetic complications, like nerve damage and heart disease.
