Because it is a disease caused predominantly by wear and tear it is most commonly found in older people. Overuse of a particular joint can result in osteoarthritis. The disease is most prevalent in older, white females who are overweight.
Rheumatoid arthritis on the other hand is cause by inflammation in the joints which causes the cartilage destruction. With regards to diet and Rheumatoid arthritis it has been well documented that a diet which is anti-inflammatory in nature can ease and even abate symptoms of the disease. Up until recently however the only reason for dieting when one was inflicted with osteoarthritis was to keep excess weight off so that more stress is not put on the joints. There is something short sighted in this approach however because when one has osteoarthritis, inflammation does occur as a result of physical damage. This inflammation causes further pain in the joints, so opting for an anti-inflammatory diet can be of great benefit to sufferers.
