Green tea releases catechin, an antioxidant with proven anti-inflammatory and anticancer properties. Research found that drinking 2 to 6 cups a day not only helps prevent skin cancer but might also reverse the effects of sun damage by neutralizing the changes that appear in sunexposed skin. Other studies show that green tea-infused with another antioxidant called epigallocatechin gallate (EGCG)-can boost your cardiovascular health and reduce the risk of most types of cancer.
