Man, here's the thing. I can't digest fermenting ogliosaccharides, disaccharides, monosaccharides and polyols.
So no beans, mushrooms, onions garlic wheat rye or barley, apples, apricots, most berries, etc etc etc.
I also lead a "fairly" active lifestyle against my own wishes. So where does my protein come from? Meat. Chicken, eggs, and hard tofu.
If I cut meat from my diet, I'm eating three meals a day of hard tofu. What even is the point of life, then?
