Researchers Find Strong Link Between Healthy Bones And Green Tea

March 28, 2017: 12:00 AM EST
A Chinese analysis of data from 15 studies found that green tea (Camellia sinensis) and a key compound known as EGCG (epigallocatechin gallate) tend to increase bone mineral density. However, the analysis of data from nearly 139,000 people stopped short of saying drinking green tea was linked to a reduced risk of fractures. The researchers suggest that the benefit of green tea regarding osteoporosis derives from its polyphenol content: as much as 40 percent of water-extractable polyphenols. Other teas contain much less. The researchers also suggest that green tea may act by boosting the creation of cells responsible for bone formation (osteoblasts) or suppressing cells that weaken bones (osteoclasts).
