I have IBD and definitely believe there is an association. But it still goes back to my question about "is there a safe limit". I think in particular for IBD, IBS, Crohn's etc, my suspicion is that there are two mechanisms at play with ultraprocessed diets:
1. Additives + microplastics in modern diets doing bad things to the microbiome.
2. Fiber intake is being reduced by ultaprocessed diets. I think the lack of pre+pro-biotics is a big deal, and ultraprocessed foods contribute to their reduced intake.
