Drinking four to six cups of steeped green tea daily coupled with an exercise regimen improves bone health and reduces inflammation in postmenopausal women, according to new research presented at Experimental Biology 2011 on April 10.
Researchers at the Laura W. Bush Institute for Women’s Health at the Texas Tech University Health Sciences Center investigated the potential for green tea to work synergistically with tai chi in enhancing bone strength. They conducted a 6-month double-blind, placebo-controlled, intervention trial that involved 171 postmenopausal women with a median age of 57 who had weak bones but not full-fledged osteoporosis. The subjects were divided into four groups—placebo and no tai chi; green tea polyphenols (GTP) (500 mg/day) and no tai chi; placebo and tai chi (3 times/week); and GTP and tai chi.
Women who consumed a level equivalent to about four to six cups of steeped green tea daily and participated in tai chi showed enhanced markers of bone health by three and six months. They also had increased muscle strength at six months. The finding suggests green tea and tai chi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well.
