If you’re going to make an Asian-inspired dish, rice noodles imported from China seem like the obvious choice. They add a little authenticity to your meal, and they generally taste quite good.

Unfortunately, the factories that produce rice noodles have been known to use sulfur dioxide. In theory, the chemical helps the noodles appear “fresh”. In practice, however, sulfur dioxide has been linked with cancer. Stay away from this harmful chemical and try to find a source for your noodles that’s a little closer to home.
