Since we’re not starving to death, in fact are more likely to be obese, the addition of fiber can be a good thing. It helps move the starch molecules through the stomach and small intestine faster so they don’t cause a blood sugar spike, and helps you feel full longer. In the case of cheese, which is very constipating, the addition of fiber can mitigate that effect. It’s good for the bowels and may help prevent hemorrhoids. Psyllium is more effective because it absorbs water and surrounds the starch and fat molecules, but it has a negative effect on the texture of dough and would make the grated cheese more gluey rather than keeping it from sticking together. Cheese itself isn’t starchy but it’s often eaten with starch, like pizza crust or croutons. Wheat bran is full of cellulose, it’s part of why whole-wheat flour is healthier.
