The poison gas phosgene, first used extensively as a chemical warfare agent during World War I, can cause a horrific lung disease called bronchiolitis obliterans. Bronchiolitis obliterans causes your small airways (bronchioles) to become obliterated, a generally irreversible and fatal condition that may also be caused by butter-flavored microwave popcorn.
I’ve warned previously about diacetyl, the artificial butter flavoring being linked to a condition known as “popcorn lung,” where workers who had been exposed to diacetyl started dying. It turns out that the industry knew about the dangers for decades, but covered it up. Even when the industry admitted workers were dying, they swore the chemical was safe for consumers—that it was only an occupational health hazard. In fact, they even had ads with Orville Redenbacher telling consumers to breathe deeply.
I quipped in my previous video Is Artificial Butter Flavor Harmful? that any ingredient requiring the use of a gas mask is probably not something you want to feed your family. I wanted to err on the side of caution and I’m glad I did.
A group of researchers compiled a series of cases of butter-flavored microwave popcorn consumers developing bronchiolitis obliterans:
- A 47-year-old woman who consumed 3-5 bags a day and now can’t even walk without getting out of breath. She’s awaiting a lung transplant.
- A 56-year-old man ate 2-3 bags a day before he started to cough up blood. His doctor alerted the FDA, but it’s still on the market.
- A third ate 1-2 bags a day and she ended up with lungs so scarred they had what’s called “honeycombing” and patches with the appearance of ground glass.
The chemical is found in real butter, too, but it’s heavily concentrated when added as additional flavoring. Tragically, it remains on store shelves and legal to this day. The regulation of health hazards from food additives has simply “fallen between the regulatory and health surveillance cracks,” the authors of the case series lament. They recommend a series of steps to protect consumers, such as allowing the bag to cool completely before opening (but who wants cold popcorn?) and then opening in a well-ventilated area away from the face. One solution they didn’t mention that would also eliminate the risk of lung disease? Don’t buy it.

Anyone have any good recipes for making air-popped popcorn delicious? I spritz with some Bragg’s and apple cider vinegar, and then sprinkle on chlorella and nutritional yeast.
