I have been eating a raw ,vegan lowfat for over 5 months, it has really helped me. I did the raw vegan diet wrong at first by eating a lot of nuts ,(cashew dip) and then I found that eating raw vegan really helps my joint pain and swelling.
Also, keep moving and incorporate a green juice everyday. Also too much natural sugar bothers me too.
If you want to get out of a nasty flare just juice celery and cucumber juice for the day and eat raw greens, your pain might drop like mine to a 3 out of 10.
I have followed a couple people on Youtube.com for recipes
"raw food romance"
"healing josephine"....she is in remission from RA after two years , she incorporated raw food for one year as well as intermitant fasting and eats two meals and stops eating around 4pm everyday.
Diet change has improved my RA. I feel best eating raw veggies and some fruits and avoiding grains, sugars, nightshades, beans and dairy. Sed rate dropped from 65 to 19, but it took over a year.

excess fat/oils = pain for me
