Recently, the Taiwan National Cheng Kung University, a study shows that the average daily drinking black tea, green tea, oolong tea cups at least 6 years can be strong bones. Because the elderly with low bone mineral density caused by osteoporosis and fractures is increasing. According to WHO estimates that by 2050 the number of hip fractures will rise in 1990 to 1.7 million to 6.3 million. Researchers believe that tea contains fluoride, caffeine, phytoestrogens may have bone mineral density (BMD) affected.Through the questionnaire survey of the study habits of tea drinking and other lifestyle characteristics. Using dual-energy X-ray absorptiometry measured body, lumbar spine (L1-L4), proximal femur BMD. (ArchInternMed2002, 162:1001) showed that 502 (48.4%) were due to tea-drinking habits, tea time, an average of nearly 10 years. When compared with non-tea drinking habits, tea drinking 6 to 10 years were higher lumbar spine BMD, tea for over 10 years were the highest of all measured parts of the BMD. In the multiple stepwise regression model, sex, age, body mass index, tea-drinking habits, the overall power of activity is the main variable in different parts of BMD. With regard to the behavior characteristics of tea, tea time is the only independent decision BMD indicators. Researchers believe that tea-drinking habits, particularly the more than 10 years, the adult body, lumbar spine and hip BMD in a significant benefit.
