Adding whey helps *a lot*. Looooong, slow cooking helps to break down those simple carbs. that are undigestible. What happens when something moves through into the large intestine undigested (most digestion occurs in the small intestine), bacteria (rather than digestive enzymes) go to work on it, causing the gas. So, breaking down those simple carbs. or "pre-digesting" them is what makes sure that the digestion takes place where it needs to take place.
Sprouting also breaks down those particular sugars (simple carbs.).
