The latest research by Australian researchers shows that drinking tea can reduce the incidence of bone loss and osteoporosis, and the results are published in the American Journal of Clinical Nutrition. The results show that women who drink tea regularly, especially elderly women, have higher bone density than women who don't drink tea, and tea drinkers have higher bone density content and less bone density loss. Researchers in Taiwan Province Province have found that drinking an average of two cups of tea a day, whether it is black tea, green tea, oolong tea or Tieguanyin, for at least six years, will help strengthen bones. Studies have shown that the role of tea polyphenols in tea is similar to estrogen, which can prevent bone loss.

Professor Shao Wanfang of Yunnan Agricultural University found that the blood calcium level did not change during the three-month observation period.

Professor Chen Liying from Jilin Institute of Traditional Chinese Medicine studied the effect of drinking tea on bone mineral density and estrogen in ovariectomized rats. The results show that feeding rats with black tea and Pu 'er tea can prevent the decrease of estrogen in ovariectomized rats and prevent the loss of bone mineral density caused by estrogen decrease. This result explains the observation that drinking tea can prevent osteoporosis at home and abroad from the level of animal experiments.
