More anecdata here. For various health reasons, about six months ago I started eating beans every day for lunch. At first it was… intense. But within a few weeks, the gas entirely disappeared. I now have no issues whatsoever.

FWIW, some beans are easier on my system than others. Kidney beans (sadly), my favorite, can be murder if you don’t cook them thoroughly enough. Lentils, on the other hand, seem to be pretty gentle. They also soak up whatever flavor they are cooked in so they are a great “starter bean” if you want to eat a more vegetarian diet.
