(The pigment which gives tomatoes the red colour) is a scavenger of singlet-oxygen, offering powerful antioxidant activity.

Free radicals, as you may be aware, can cause cell damage that may contribute to the development of cardiovascular disease and cancers. Thus, vitamin A and related nutrients may collectively be important in protecting against conditions related to oxidative stress, such as aging, air pollution, arthritis, cancer cardiovascular disease. Cataracts, diabetes mellitus and infection. However, this role has not been consistently demonstrated in humans.
