I lived for almost a year on baby food with very little else added. I bought the fruits and the vegetables. I also had baked potatoes, sweet potatoes, rice, plain chicken.
Now I am on a completely gluten free diet and am doing great. Although there are still food I can't eat, I am as close to remission as I will ever get.
The baby food diet was difficult to be sure, but it was so easy on my body. I know it sounds crazy, but for me at least, it worked.
