Green Tea and Tai Chai Team Up to Protect Bones

Green Tea and Tai Chai Team Up to Protect Bones
Green tea is one of the latest superfoods making its way into bottled waters and energy drinks.  You'll even find it in energy bars, mints, chewing gum and ice cream. It has many claimed health benefits.  Texas researchers add to the list with evidence that green tea aids in the prevention of osteoporosis.  Especially when coupled with a tai chi practice. 
Green tea is full of compounds called polyphenols which are known for their potent antioxidant activity. Studies have shown that people who consume the highest levels of green tea polyphenols tend to have lower risks of several chronic degenerative diseases such as cardiovascular disease.
Animal studies suggest that the mechanism behind this correlation may have to do with lowering chronic levels of inflammation.  These studies show that green tea may benefit bone health by mitigating bone loss due to aging, estrogen deficiency, or chronic inflammation.  That in turn may improve clinical symptoms of rheumatoid arthritis, normalize bone metabolic disorders, and impact trace element metabolism.
In humans, the Mediterranean Osteoporosis Study showed that drinking up to 3 cups of tea per day was associated with a 30% reduction in the risk of hip fractures in women as well as men over 50 years of age.
Researchers at the Texas Tech University Health Sciences Center believe bioactive components in green tea might decrease the risk of fracture by improving bone mineral density.  These compounds may support osteoblastic activities (bone building) while suppressing osteoclastic activities (bone breakdown).
