Flavonoids
Flavonoids are antioxidant phytochemicals that form the water-soluble colors of vegetables, fruits, grains, leaves, and bark. Flavonoids come in many forms, and different plants contain different concentrations of them. Some flavonoids may have up to fifty times more antioxidant activity than vitamins C and E. Impressively, flavonoids from red grapes are more than a thousand times more powerful than vitamin E in inhibiting oxidation of human LDL cholesterol. A steady intake of flavonoids can do a lot for your health.
