“Carotenoids” – chemicals produced by higher plants that function to protect the plant from the oxygen-based free radicals produced during the absorption of light. Carotenoids also act as pigments to aid in light absorption. In our bodies, carotenoids function to protect our cells from free-radical damage. Several carotenoids enhance immune response, help prevent cancer and […]
