According to Dr Chwan-Li Shen, Green Tea and Tai Chi enhance bone health and reduce inflammation in postmenopausal women.
Dr. Chwan-Li (Leslie) Shen is an associate professor and a researcher at the Laura W. Bush Institute for Women's Health at the Texas Tech University Health Sciences Center and has conducted a study focused on postmenopausal women and investigating the potential for green tea to work synergistically with tai chi (an eastern fitness activity) in enhancing bone strength after the menopause.
She carried out a double-blind, placebo-controlled, intervention trial which involved 171 postmenopausal women with an average age of 57 years old, who had weak bones but not full-fledged osteoporosis.
The study lasted for 6 months, during which time blood and urine samples were collected and muscle strength assessed.
The results show that drinking about 4 to 6 cups of steeped green tea daily and doing tai chi, enhanced markers of bone health by the third and sixth month. A similar effect was found for muscle strength after six months. Participants taking tai chi classes also reported significant beneficial effects in quality of life in terms of improving their emotional and mental health.
What she found important was the substantial effect that both the green tea and tai chi had on biological markers of oxidative stress. Because oxidative stress is a main precursor to inflammation, this finding suggests that green tea and tai chi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well.
Dr. Shen and colleagues hope to soon complete a more long-term study utilizing more technically savvy measures of bone density.
In the meantime, I for one, will be enjoying my well earned cuppa green tea!
