Most of us have heard that green tea is good for us, but why? The answer is that drinking green tea provides many health benefits, including:
- heart health— drinking tea is associated with lowering one's risk of heart attack and stroke
- bone health— antioxidant and anti-inflammatory activity of green tea help diminish bone loss
- oral health— green tea is a natural flouride source which helps decrease tooth decay
- weight loss— the catechins in green tea produces thermogenesis (heat in the body related to burning calories)
- cancer prevention— the catechins in tea prevent cell mutation and reduce tumor formation
Just as important, and the subject of this blog, is that green tea can help balance your hormones. The biochemicals in green tea can change a woman's estrogen metabolism, and as you may know, estrogen dominance is undeniably linked to breast cancer.
Researchers, led by Dr. Barbara Fuhrman of the NIH's (National Institutes of Health) Cancer Institute, tested urinary estrogens and metabolites among 181 Japanese American women from California and Hawaii. Of these healthy women, 72 were potmenopausal. Along with urinary testing, personal interviews were taken, and each woman's consumption of green tea, black tea, coffee and soda were recorded, measured, and adjusted in respect to caffeine consumption.
Amazingly, postmenopausal women who drank green tea daily had 20% less urinary estrone and 40% less urinary estradiol levels (meaning these women metabolized estrogen better). It was found that black tea did not produce the same results as green tea, and interestingly, caffeine consumption did not change the results.
Even more interesting, and perhaps concerning for pre-menopausal women, was the result that the estrogen levels of pre-menopausal women did not respond to green tea at all.
So, what does it all mean? What should you do with this information?
Well, if you are postmenopausal, drink green tea! It will help metabolize estrogen and can help in the prevention of breast cancer.
If you are pre-menopausal, drink green tea! Even though it will not have the same cancer-reducing results, green tea still has wonderful health benefits. Try other, more natural remedies for PMS symptoms, instead of using the birth control pill (which increases risk of breast cancer).
If you are experiencing symptoms of the change in life we call "menopause" (technically it is "perimenopause"), drink green tea! Remember to steer clear of HRT (hormone replacement therapy) because it too is associated with increased risk of breast cancer. Instead, try Menopause Relief Herb Pack for uncomfortable symptoms such as hot flashes, night sweating, insomnia, headaches, and mood swings.
