Recently many green tea foods have been popular in Japan. In fact green tea is good for our health. I wonder how it affects the human body. There are three effects. First, green tea contains abundant vitamins. Second, it contains potassium that prevent swelling. Third, if we eat or drink it, we could live a long life. According to university of Touhoku project, over 50 years old women who drink green tea could live longer than women who don’t drink it. So I recommend people should drink or eat green tea foods!
