I have tried different diets (for myself).
Firstly I would like to mention that I beliefe that diet can just be the additional part to diet, but - no doubt - a very critical one.
So, I tried different diets BEFORE being diagnosed so that's a completely different issue, would be more something like curing a disease with just diet. I've been vegan before diagnosis, also went gluten free and vegan, was a raw vegan for a few weeks (felt horrible), also tried low carb while being vegan (tofu, tofu, tofu, NOT healthy).
After being diagnosed I knew that my diet was not the problem but a physical problem in the intestines. So I slowly changed my view from eliminating (also tried SCD while being on different medication one after another) to thinking more about nutrition, in terms of giving the body what he needs, in an easy absorbable less-irritating form. I'm working with a nutritionist that I see regularly which was very helpful. I have to add that she has specialised in IBD, so most nutritionists will only rely on what they have learned from books which I found not to be helpful for me.
I'm eating fish (omega 3), protein rich dairy (quark, skyr etc.), egg and lots of vegetables, preferably all components of carbs, fats and protein on my plate, especially fats which slow down digestion in the small intestine (released into the small intestine in small portions from the stomach). Apart from that I don't eat sugar, just fruits in my quark with linseed oil for breakfast. If I do eat sugar, I see negative reactions (it's scientifically proven that gut flora plays a critical role in IBD, sugar can worsen the gut flora towards an environment that promotes inflammation).
I also don't eat nuts (feels like stones going through my gastrointestinal tract, don't want to feel that ever again), raw vegetables (eating raw carrots would be like suicide for my gut), sauerkraut, cale, beans, whole grain etc.
So I seem to do best on a protein-rich vegetable based diet with mainly cooked meals, eating regularly, small portion sizes, not too many carbohydrates. But without restricting, everything in moderation. If I want to eat something, I eat it but nut by itself but before or after a meal (helps tolerating it then). Also I try to eat a large variety of foods.
Hope you find a good way diet-wise for your son!
