New research presented last week at the Experimental Biology conference in San Diego, California, suggests that regular grape consumption may help alleviate pain associated with symptomatic osteoarthritis of the knee, and improve joint flexibility and overall mobility. Researchers attribute these potential benefits to the polyphenols found in grapes.
The sixteen week clinical study, undertaken by Texas Woman’s University, was designed to investigate the benefits of grape consumption on inflammation and osteoarthritis outcomes. 72 men and women with knee osteoarthritis (OA) were assigned to either consume grapes in the form of a whole grape freeze-dried powder, or a placebo powder.
