Starches and sugar really increase my pain. I try to stick to an anti Inflammatory diet tha my chiropractor gave. Basically 50% of your meal intake should be vegetables (mostly leafy greens) and 25% protein(wild or grass fed only). 20% whole grains but not every day. 5% good fats , fruits. I always know when I haven't followed this because my pain is horrible. I find it also helps me to eat 5 to 6 smaller portion meals a day instead of large meals. I usually make soups in big pots that incorporates what I am suppose to have then I can freeze them individually and it makes for easy meals and helps me stay true.
Oh yes. Sugar definately increases my pain. I still need to learn to pass up those "special treats" that do more harm than good.
I do notice.. a big difference.. dairy is a big one for me as well
