I have in the past and found it lessened my pain alot. I struggle to get the nutrients due to my busy fast paced life and commitments so have the inflammatory foods in small amounts (avoid but not eliminate) and it has helped alot too.
I have found a paleo works. I use a modified Wahls Protocol. Basicly is no dairy except good cheeses, No white sugar, ie no white potato, corn, corn products, No breads/gluten . No nitrates, No prepared meals. As much organic as my funds allow, No GMO foods. To do the clean eating and find your foods that are your triggers you have to go cold turkey on all the no's. Then after 6 to 8 weeks you can gently add one back in. I wanted pasta once and during the one time I added it in I was in pain before I could finish a half cup of it. That pain was my back and my gut. My husband was being a baby about the loss of his comfort food but by the 2nd week he had lost 5 pounds, not gasy, even said he slept better. Me, by 6 weeks I had lost 10 ponds, No loose stools, No gas, even had energy and noticed that I don't have pockets of fluid around my spinal area where my cysts are. Oh one thing that helped mentally was not calling it a diet, it is a life style change.
