I do not know if it is strictly genetics or if it has something to do with our diet, but my entire family has had terrible cases of arthritis. When I was growing up I could see the horrible effects that it was having on my loved ones and I vowed never to do that to myself. I have always investigated arthritis food and made sure that I was always in proper nutrition and worked out regularly. I have yet to have any conditions to arthritis and I truly believe now that it is just brought on by diet and not necessarily genetics.
