Gosh, I think I have tried all these remedies except the baking soda. So I will try that. "They" say that if you eat those kinds of vegetables, beans, cabbage, etc, a lot, your digestive system will adapt, and stop causing so much trouble. I don't know how often you would have to eat them, maybe daily? For me, there is a cumulative effect. If I cook a pot of beans, the first meal is a little annoying, but if I eat leftovers the next day, it gets really bad.
Does anyone soak their beans with a little apple cider vinegar? It is supposed to free up the nutrients so they will be more nutritious to eat. Then rinse before you start cooking. Then I guess if you add the baking soda, you won't cause a volcano.
