The FDA justified this, that there is no clear evidence for this claim. High cholesterol studies show that green tea lowers total cholesterol and increase HDL (“good” cholesterol) in animals and humans. A clinical study showed that men who drink green tea have rather low total cholesterol values than those who drink a cup of green tea. Results of an experimental study in animals suggest that polyphenols reabsorb it in green tea of cholesterol in the intestine, prevent and help the body to get rid of cholesterol. In another small study with male smokers, researchers found that green tea significantly reduces the harmful LDL-cholesterol in the blood.
Cancer several clinical studies have shown that green tea and black tea may protect against cancer. For example, the cancer rates in countries such as Japan, where people consume regular green tea are very low. However, it is not possible to claim that green tea can actually prevent cancer in people with security. Recent clinical studies indicate that the polyphenols found in tea, especially green tea, play an important role in the prevention of cancer. Also, researchers believe that the polyphenols prevents the growth of cancer cells and can even kill. Bladder cancer. Only a few clinical trials have the relationship between bladder cancer and tea drink studied. In a study that compared people with and without bladder cancer, researchers found that women of the black tea and powdered green tea (Matcha tea) drank less susceptible to the development of bladder cancer were.
A follow-up study of the same group of researchers showed that people had a better 5-year survival rate with bladder cancer – men, in particular – who drank green tea, as those who did not. Breast cancer. Clinical trials in animals and cells in test tubes, suggest that polyphenols in green tea inhibits the growth of breast cancer cells. In a study of 472 women in various stages of breast cancer, researchers found that the women who drank lots of green tea, had the slightest spread of cancer.
