Healthy bones
The antioxidants present in oolong tea protect teeth against decay, strengthen the bone structure, prevent osteoporosis, and promote normal, healthy growth of the human body. A number of studies analyzed the long term effects of drinking tea, particularly on bone mineral density (BMD). It showed that people who consistently drank black or oolong tea for more than 10 years were tremendously less likely to lose their bone mineral density over that span of time. It is thought that some of the components in tea actually stimulate the retention of minerals from other food that we consume.
