A team of Japanese researchers in Osaka have found that theaflavin-3, or TF-3, a substance in black tea, is effective for bone loss treatment. I’m not sure exactly how it will work, but if it does really work, that’s a great news! Come to think of it, I have done a medical check for bone density before. The result showed no problem! Rather, it was much better than the average figure. No wonder….:-)
