Chili peppers are famous throughout the world from the fiery cuisines of Mexico, India, Thailand and Africa to the subtle flavor enhancement of the most delicate dishes. The hot varieties can also be picked at any color stage, but are hottest if allowed to fully ripen. Chili peppers ripen through a wide range of colors from yellow, orange, purple and even brown. Some chili peppers turn bright red, which is more often an indication of ripeness rather than hotness.
In general, all peppers are a good source of vitamin A and C; the red ones are bursting with these two antioxidants. Antioxidants are a group of nutrients that neutralize free radicals in the body fluids reducing the risk of disease.
Free radicals are naturally produced when the body uses oxygen. Unless they are neutralized, they cause cell damage, which may lead to health problems such as arthritis, heart disease and cancer. A single raw red pepper, sweet or hot, can meet the daily requirements for two important antioxidants, vitamin A and C.
