This drink has already been and still is the subject of various studies, the aim of which is to better understand its possible curative role. Most of the benefits of green tea would appear to depend on the presence of large amounts of catechins, able to strengthen the antioxidant defenses and therefore reduce the damage to the cells, with positive effects on all tissues. In particular green tea would have properties anti–cancerous (protects good cells from mutations and inhibits the growth of cancerous ones) and would benefit the cardiovascular system (inhibits clot formation, reduces the presence of grassi e cholesterol in the blood and slows down the development of atherosclerosis and coronary heart disease) e respiratory (it is particularly useful against the negative effects of smoking).

Since green tea contains caffeine (about 12 grams per 100 ml of drink), it is advisable not to let children drink it“.
