Popcorn cravings

Hey beautiful mommas! I'm 30 weeks along and have been craving popcorn a lot lately. But my husband keeps yelling at me not to eat because it's not good for the baby. I feel so irritated and don't feel like eating anything at all when he does that! I keep showing him articles as to popcorn isn't unhealthy but he doesn't just get it. Some advice on dealing with this will be greatly appreciated.
