The polyphenols also exert important effects inhibit the initiation of atherogenesis, resulting from the oxidation of LDL. Also exert hypocholesterolemic and vasodilating effects, acting on enzymes and / or metabolites involved in these effects. Tea consumption also improve the quality of life and that trigger the mobilization of fat in adipose tissue, stimulating thermogenesis and promote a better maintenance of bone mass due to its fluoride content.
