Green tea is found to raise BMD

Drinking green tea protects against osteoporosis by increasing bone mineral density (BMD), according to Japanese research presented at the conference.

The study asked 655 women over 60 about their intake of green tea, dairy products, fish, vegetable and tofu, as well as their smoking status, alcohol consumption, level of physical activity and use of drugs for the treatment of osteoporosis.

The BMD of their lumbar spine, serum calcium and other biochemical markers were measured.

The 600 women who drank green tea five days or more per week had a higher BMD than that of those who drank green tea less than five days per week.

The researchers believe that the flavanoids in green tea could increase BMD either through an oestrogenic effect or by promoting the apoptosis of osteoclasts.
