There is alot of arthritis in my family and as such it is something I have always been aware of. There is a book that I use occasionally as I'm only in my 30's so only get the odd twinge at the moment, It's called 'Eat to beat arthritis. There has been alot of research into food that effects it, for example avoiding tomatos and rhubarb (2 of my favourites) really helps because of the acid in them. Also taking supplements of molasses (found in black treacle, yuck!) has been proved to help.
Playing the piano is a brilliant thing for it as it keeps the fingers working, so giving up is absolutely the worst thing she could do, although it might be painful it is far better than the alternative of not being able to move them at all, and still having the pain.
Also avoiding apples and especially citrus fruits, they are the worst for acids that collect in the joints. I had a friend who was convinced she was becoming arthritic, she went to the doctor and he asked her if she drunk a lot of fruit juice. She did, she was a sucker for orange juice and would drink nearly 500 ml of it a day - because she thought it was healthy. She was told to cut out the orange juice altogether and avoid acidic fruits. She did and within three weeks all the stiffness in her joints had gone.
I can highly recommend glucosamine and chondroitin supplements too. My formerly dodgy right hip (from a fall off a horse) no longer gives me any bother, even on the coldest and wettest days. Be aware though that it is possible to be intolerant to the glucosamine, it can upset some peoples stomachs, but I don't think side-effects like that are very common.
So tomatoes aren't good for us and yet the lycopene(sp?) is good for the skin and acts as an anti-oxidant. You can't win, whatever you eat. I believe everything in moderation, possibly the best way to avoid sudden onset of a food intolerance or the opposite by being deficient in some essential mineral/vitamin.
I agree with the advice of keeping the hands moving. The very reason our joints 'stiffen' as we get older is because we simply don't move them around enough. Unless someone has a medical reason not to move in a particular way, then keep that body moving. Dancing is far better for you than going to the gym or jogging (huge strain on the hips, knees and ankles).
