I have extreme C and bloat and here are my thoughts if I were trying to follow your diet. For me ANY type of bran kills me (more C and bloat). Also I can't mix IF/SF/Protein the way you are. It's too much for my stomach to handle. I stick with one type of food at a meal and it helps. For a lot of us lettuce is majorly constipating- maybe try eliminating it. Again with your lunch, my type of C can't handle the IF (lettuce) with the SF (bread) and protein. Maybe try combining proteins with IF alone at meals and keeping your SF's together. It helps to see how your gut reacts to each type of fiber/food on it's own so you can try to resolve how the different symptoms get jumbled together. At least that works for me- we are all different tho!
