Green Tea And Bone Health

Post by tex »

Apparently one of the ingredients in green tea, epigallocatechin, (EGC), not only helps to increase bone formation, but it also helps to prevent resorption and/or weakening of existing bone.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.

Hmm, it said that weight is a factor. I thought osteoporosis was more common in skinny people?
Hope this study's right. Somewhere I thought I read something about tea being bad for the bones.
Think I'll see if I can find something to the contrary. Maybe it had to do with the acid or something.
Thanks for the information. This is an important topic to so many of us!
Yours, Luce

From the article:
and obesity adding extra strain on bones.
Clearly, they're referring to the fact that extra weight adds to the risk of fractures, if osteoporosis is present, (that's not saying that obesity has an effect on bone mineralization or resorption, per se).

The article is about the advantages of green tea, specifically:
Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent.
But it appears that all tea has a beneficial effect, (though green tea may have a greater positive effect). Some authorities have suggested that caffeine reduces bone mineral density in women, but that risk, (if it even exists), is apparently not associated with drinking tea:
Conclusions: Older women who drank tea had higher BMD measurements than did those who did not drink tea. Nutrients found in tea, such as flavonoids, may influence BMD. Tea drinking may protect against osteoporosis in older women.

Doesn't green tea have half the caffeine of regular tea? I wouldn't mind trying it if that is so. I'm not supposed to drink caffeine for another reason.
