I agree with the poster who wrote to avoid the nightshade vegetables. I have had rheumatoid arthritis for 15 years, fibromyalgia for longer than that and have been on tons of medicines that have caused worse side effects than the RA and fibro themselves. (Methotrexate, Enbrel, Arava.....)
Two years ago I gave up grains and sugar, along with the nightshades veggies. I saw incredible improvement and lost 40 lbs......but was still not 100% healed which was my goal. I added dairy free and that was what helped me over that last hump.
I don't take any meds any more. At all. If I work too hard in the yard I might have to take some naproxen or soak in an epsom salt bath. I supplement with magnesium, vit D, co-Q, zinc and selenium and get lots of sleep. I try to keep my stressors to a minimum.
I don't eat anything processed any more. I don't necessarily eat organic since it is cost prohibitive, but I try to eat my food as close to the way God made it as possible. lol
Some famous ancient person (Aristotle? Socrates?) said that "All disease begins in the gut" and I believe it.
Everyone's body is different and we all have to find what works for us. Good Luck and God Bless you on your healing journey!
