In the 14 million dollar Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT) sponsored by the National Institutes of Health, 1,583 people with osteoarthritis were tested for the effectiveness of Glucosamine/Chondroitin. The participants were split into 5 groups consisting of; those given placebo, those given celecoxib (trade name Celebrex), those given Glucosamine, those given Chondroitin, and those given a combination of Glucosamine and Chondroitin. In the low to moderate pain level celecoxib had the best result, however, within 6 weeks the combination of Glucosamine with Chondroitin reduced the level of pain by 25% in the moderate to severe pain range group where celecoxib was no better than placebo.

In this study of 470 elderly men aged 65 to 84 in the Netherlands it was found that those who consumed the most cocoa had a 50% decreased risk of dying from heart disease or any cause mortality compared to those men who did not consume cocoa. The polyphenols in the cocoa improved the function of the endothelial cells that line blood vessels and lessened the risk of cholesterol or other compounds leading to heart attacks, cancer, and lung diseases.The study was performed over a 15 year period. The study is published in the February 27th, 2006 issue of Archives of Internal Medicine.
