If you wanna lower your risks of developing cancer, you might wanna drink more green tea.

Green tea has been found to fight risks of some blood cancers. According to a stufy from Japan, the recommended dosage is about 5 cups a day.

Dr. Toru Naganuma, at Tohoku University School of Medicine in Sendai, Japan emailed Reuters Health that drinking green tea has been associated with lower risks of dying and heart disease deaths.

Dr. Naganuma and his team of researchers gathered information on the diets and green tea drinking habits of a large group of Japanese adults aged 40 to 79 years old, and then followed the group for development of blood and “lymph system” cancers. The lymph system is a major component of the body’s immune system. The participants have no previous history of cancer.

In the 9 years of observation, 157 blood, bone marrow, and lymph system cancers developed in the study group. The research team found that the overall risk for blood cancers was 42 percent lower among study participants who drank 5 or more, versus 1 or fewer, cups of green tea daily.
