Addition of milk does not alter the antioxidant activity of black tea

摘要: Tea is a polyphenol-rich beverage like wine and catechins are its chief polyphenols. Catechins have cardio-protective effects as they can scavenge free radicals inhibit lipid peroxidation. Epidemiological studies indicate an inverse relation between tea consumption the risk of cardiovascular other chronic diseases. Addition milk to black has been reported adversely affect beneficial effects, but data not unequivocal. Therefore, we assessed effect addition on ability modulate oxidative stress antioxidant status in adult male human volunteers. Although area under curve plasma was lower with compared tea, it did total activity, resistance oxidation induced ex vivo, decreased urinary thiobarbituric acid reactive substance levels. The results suggest that may obviate subjects with/without prevents damage vivo.
