When acting as antioxidants, carotenoids have been shown to reduce the damage caused by certain molecules called free radicals.
A generous amount of these chemicals might prevent damage to cells and tissues as well as genetic damage.
This means that they might increase a person's immunity to infection, protect against cardiovascular disease, reduce the risk of cancer for example colon, skin and esophagus, protecting against cataracts and age related macular degeneration.
