Green tea has been the subject of much health buzz in recent years, and with good reason. Compared with regular black tea, green tea looks weak and insubstantial. But this mild-mannered drink contains a natural antioxidant called epigallocatechin-3-gallate (EGCG) not found in black tea. Studies suggest that EGCG works to stop the production of certain inflammatory chemicals in the body, including those involved in arthritis. Preliminary research suggests that EGCG and other catechins in tea may prevent cartilage from breaking down, possibly helping to preserve joints longer.
