Popcorn linked to "popcorn lung" disease

An ingredient in microwave popcorn, which gives it a distinctive buttery aroma, has been linked to a rare lung disease called "popcorn lung".

The disease was named like that because it was found in popcorn plant workers exposed to a flavoring ingredient called diacetyl. Diacetyl is a natural substance heated in a factory setting to give microwave popcorn its buttery taste.

Recently a man, who consumed large amounts of popcorn, was diagnosed with "popcorn lung".
