Great that you are focusing on diet and other healthy steps. Legumes tend to irritate my GI tract, other than miso and other fermented (celiac and microscopic collitis). Hemp pasta is high in fiber/protein/complex carbs and behaves like wheat pasta. Toasted cooked quinoa seeds are a good substitute for rice (more protein, more complex carbs, no arsenic) and I add teff, quinoa, amaranth, and pumpkin seeds to my sourdough bread. We are still omnivores, but eat minimal meat. A shame that it is hard to find good vegan food in restaurants.
