I wouldn't eat any other kind of bread than sourdough. But even the most nutritious bread, sourdough, has potentially problematic amounts of resistant starch that is not helpful with IBS and increases bloating. Feeding the microbes produces SCFA, lowering pH that may prevent bacterial overgrowth, but does not change the microbiome composition much. Although the wheatbran is good fiber, the additional resistant starches only slightly shortened transit times, thus is not as effective in preventing colon cancer as just using the wheat bran by itself. A plus is that the degraded phytates make the minerals available and the degraded gluten prevent further inflammation in the case of leaky gut and IBS.
I think the poo nuggets indicate that your guts transit rate is not yet fast enough. What works better for me is to first process the milk by cooking it and adding it to mashed potatoes, it changes some of the milks protein structures I guess that makes it more tolerable and produces less mucus in my airways. This is especially true for A1 milk. But A2 milk or goat milk gives me less problems, just like greek yoghurt and cheese.
Adding cooked wheatbran to greek yogurt seems to me the best way to increase gut transit rate. And is not so annoying as eating carrot between meals.
I know it has iron but would that pass for the time being?
Bread doesnt bloat me
