Plant proteins are all fodmaps. Beans, lentils, peas, etc are some of the worst ibs triggers out there. If I eat any of those foods I'm in excruciating pain on the toilet for a week. Not eating any protein would kill me yeah. I guess I could try to survive on powdered rice protein isolate which is the only plant based protein that doesn't fuck me up. But fuck that. More plant foods absolutely destroy me than not. Fruit? Forget it, that's fructans. Vegetables? Sure, if it's lettuce or something. Beans? Nope. Broccoli? Nope. Tomatoes? Apparently also high fodmap. Used to be low fodmap but Monash seems to have changed their mind. Sweet potatoes? You betcha that's a fodmap. Garlic and onion? Oh yeah those are the worst triggers ever. Nuts? Absolutely brutal reactions as well.

I've lived wth this shit for a decade. At first I could tolerate some fodmaps in small amounts. Recently? It's zero fodmap or I'm dying on the toilet.

I'm literally considering carnivore diet as a potential treatment. So yeah, all you lovely vegans and environmentalists are advocating for making my life either impossible, incredibly expensive, or excruciatingly painful.
