Is taking beano regularly bad for you? I'm a vegetarian.

Not at all. People can't fully digest beans because our bodies do not make enzymes that break down certain starches in beans. The bacteria in our intestines then break down the starches & produce gas. Beano provides enzymes that help to break the starches down, thus reducing gas. I know of no harm from taking beano regularly. An alternative is to sprout beans, which also improves digestibility of the starches.
