Caution, but no conclusions about consumer risk from popcorn with diacetyl

This is an interview of the doctor who reported the case of the man who developed bronchiolitis obliterans and was also a heavy microwave popcorn eater. ("I am popcorn. It is my exclusive snack-food choice. I have been eating two to three bags a day for 10 years.")

Here's that last Q&A:

So what can you say about the risk of making butter-flavored microwave popcorn at home?

You have to be very careful about inferring a causal connection on the basis of a single case report. It may not be correct. We don’t know what the risk is to the occasional consumer of microwave popcorn. More work needs to be done to try to understand the exposures. I have not
banned the use of butter-flavored microwave popcorn from my home, but we certainly don’t use it every day. That’s just our habit – we were never big consumers of butter-flavored microwave popcorn.


I like the sentence about the uncertainty of causality. It applies to the vast majority of medical stories in the MSM.
