Microwave Popcorn Gives off a Toxic Gas
The chemical in microwave popcorn, called diacetyl, is so poisonous that it often destroys the lungs of workers in microwave popcorn factories. These workers develop an incurable disease known as bronchiolitis obliterans — popcorn lung.
Health professionals have known of this risk for years always assuming that it would only affect people working in the factory and breathing the especially high concentrations there.
In 2007, a man who ate two bags of microwave popcorn daily was diagnosed with popcorn lung. This indicates that diacetyl enters the air and lungs when microwave popcorn is cooking. In response, most microwave popcorn companies removed diacetyl and replaced it with chemicals having the same effects.
