I also drink green tea every single day. Since I have been doing that, I have had not one cold. Not one.
Yes I heard green tea is good and prevents cancer. Every time I smoke I should have a glass of that stuff.
That's not going to counteract the effects of smoking because of the carcinogens in cigarette smoke. Green tea is a very minor antioxidant and it's effective in protecting healthy people from cancer-causing/contributing cell damage, but it is not an immunization against carcinogens which directly cause cancer. The type of cell damage that a green tea would protect again is the normal everyday byproducts of cell metabolism and aging. NOT a direct poisoning of the cells, such as with carcinogens. If you take in carcinogens, you are basically guaranteeing yourself great amounts of damage and a much greater likelihood of getting cancer, chas veshalom.
