I was very picky as a child, when I got my own place I tried cooking and started to like more and more stuff because I knew how to prepare them correctly. Now I have a bad case of IBS and I can't eat much variety because of it. The irony is not lost on me
Have you tried probiotics to help your IBS symptoms?
I had horrible IBS as a child and through my teens but it eventually went away as I ate more yogurts. Now the occasional probiotic pill keeps my gut happy.
I have and I remember it really helped but I had to stop because I couldn't afford it anymore for a while and I didn't start again. I had a quick look and apparently yogurt can help treat IBS but it's bonkers, like 600g a day for 400 days or so. So, I should probably give your solution a try
