A new study out of Japan found that middle-age and older women who drank 10 or more cups of green tea a day did not have a lower breast cancer risk than women who drink half a cup or less a week. According to researcher Dr. Motoki Iwasaki, a cancer epidemiologist at the National Cancer Center in Japan, the study's findings suggest that, "green tea intake, within a usual drinking habit, is unlikely to reduce the risk of breast cancer." While other studies have found green tea to have a beneficial effect, Iwasaki says this is not the first study to disprove the connection.
So why have some studies in the past suggested their is a benefit? Dr. Qi Dai, a cancer epidemiologist at the Vanderbilt-Ingram Cancer Center in Tennessee suggests that green tea may provide protection against breast cancer for women in specific age groups or with certain genetic makeup.
But Iwasaki doesn't think the conflicting evidence means we should stop drinking it. There are many types of green tea, but all contain antioxidants called polyphenols that neutralize toxic free radicals in the body. Studies have linked the tea to a decreased risk of other types of cancers, including bladder, ovarian, stomach and colorectal cancers, according to the University of Maryland Medical Center.
Am I confusing people by posting all these conflicting studies? I hope not. I'm trying to stay on top of research so that we can be informed about the potential for solid breakthroughs. So I will keep drinking green tea and reminding people to maintain a healthy bodyweight and watch their alcohol consumption. Anyone got a study to disprove those last two?!
