Green tea is one of the most popular beverages consumed worldwide and is now also available as a dietary supplement. Researchers suggest that the beverage has the potential to help in the prevention and treatment of osteoporosis and other bone diseases.
In the study, scientists noted that many scientific studies have linked tea to beneficial effects in preventing cancer, heart disease, and other conditions. Recent studies in humans and cell cultures also 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 scientists 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 found 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 scientists 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 noted.
Apart from green tea, for healthy and strong bones, make sure to include plenty of calcium, vitamin D (needed for the absorption of calcium) and good-quality protein in your diet. Eat dairy products, fish, poultry, meat, and eggs.
