Popcorn -- Salty, buttery or plain, what's a better light snack? We love to eat it at the movies, at a party, hanging out on the couch, or as munchies for last-minute guests. And nothing beats the smell of fresh popcorn at a ballgame. Popcorn lovers may be singing a swan song as their favorite all-time snack is under attack.

Who knew that getting high off the fumes of microwave popcorn would be a health hazard? Apparently, the culprit is diacetyl, a chemical that gives microwave popcorn that buttery, creamy taste.

Although, there has only been one report to the FDA -- about a man whose lungs may have been damaged while inhaling fumes from making two bags of popcorn daily -- no scientific proof has been given. Even still, manufacturers such as ConAgra and General Mills are pulling the chemical off the production line.

All-natural? Not so much -- so next time you make popcorn, you better check the ingredients and pinch your nose when you nuke the bag.
