I suspect i have oarthritis. with diet i can control the pain. i have recently started rock climbing & would hate to quit this sport but concerned about lasting effect on my joints - are there measures i can take to minimize damage & acceleration ?

Osteoarthritis: Most physicians don't feel that dietary measures prevent degenerative joint disease but keep a healthy diet nevertheless.. It is a wear and tear mechanism that, in many cases, is genetically determined. Your job is to minimize wear and tear of your joints by keeping a healthy body weight, continue regular sensible exercise, pay attention to pain in joints and prevent injury to them.
