Green tea may help improve bone health




Scientists in Hong Kong are reporting new evidence that green tea one of the most popular beverages consumed worldwide and now available as a dietary supplement may help improve bone health. They observed that the tea contains a group of chemicals that can stimulate bone formation and help slow its breakdown. Their findings are in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. The beverage has the potential to help in the prevention and therapy of osteoporosis and other bone diseases that affect million worldwide, the scientists suggest.



Green tea may help improve bone health

In the newly released study, Ping Chung Leung and his colleagues note that a number of scientific studies have linked tea to beneficial effects in preventing cancer, heart disease, and other conditions. Recent studies in humans and cell cultures suggest that tea may also benefit bone health. But few scientific studies have explored the exact chemicals in tea that might be responsible for this effect.

The researchers exposed a group of cultured bone-forming cells (osteoblasts) to three major green tea components epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG) for several days. They observed that one in particular, EGC, boosted the activity of a key enzyme that promotes bone growth by up to 79 percent. EGC also significantly boosted levels of bone mineralization in the cells, which strengthens bones. The researchers also showed that high concentrations of ECG blocked the activity of a type of cell (osteoclast) that breaks down or weakens bones. The green tea components did not cause any toxic effects to the bone cells, they note.
