Researchers from Texas Woman’s University conducted a 4 month clinical study to see if eating grapes really helps with inflammation.  72 men and women diagnosed with osteoarthritis participated in the study.  Some were given a placebo powder, while others were given a whole grape freeze-dried powder.  The study revealed that the organic chemicals in grapes known as polyphenols helped reduce pain, and improved overall mobility and flexibility.  

Another reason to consume at least one cup of red or white grapes a day is because the skins of these grapes contain another natural compound called resveratrol which is a natural COX-2 inhibitor.  COX-2 is an enzyme that is accountable for the pain and inflammation of arthritis.  NSAIDs are consumed because they work as a COX-2 inhibitor, but grapes are better for your overall health, considering the fact that you do not have to worry about liver failure from eating too many grapes.
