It's a real puzzle when you try to do this as our culture has embraced the nightshade family over and over. There are reverbrations about the brassicas as well, broccoli, brussels sprouts, etc. To me that leaves the rose family. Peaches, nectarines, plums cherries, and I guess you could throw in apples. I have the biggest list of do not eat that I've ever had, I am blood type B and I'm not supposed to eat pork, chicken, bread, and now have hereditary hemochromatosis and can't have red meat, (beef) either. Also supposed to watch dairy. That leaves eggs and fresh air. Just ate my eggs and will not go out and get my fresh air. Good Luck. Marcia
If I were you I'd look to giving up grains to help the arthritis.
