Per- and polyfluoroalkyl substances (PFAS) are synthetic chemical compounds found in a variety of food packaging. In addition, laboratory studies document that diacetyl has toxic properties as a single component that parallel the effects of exposure to a butter flavoring mixture. "Respiratory toxicity of diacetyl in C57BL/6 mice." On the other hand, NIOSH concluded that acetoin, which lacks the -dicarbonyl group, "is considerably less hazardous than dicacetyl." The challenge is that there may be a diacetyl precursor in a sample of beer that you cant taste or smell: acetolactate. Some foods out there are just a mystery to most people, with popcorn making one of the top slots on that list. Fixed Obstructive Lung Disease in Workers at a Microwave Popcorn Factory Missouri, 20002002. Moreover, diacetyl is present in cigarette smoke at levels substantially higher than those measured in the Harvard study, but smoking has never been considered a risk factor for popcorn lung, making it extremely unlikely that e-cigarettes cause the disease. For instance, I use butters and oils almost every day in my cooking, and now I am a bit concerned. food flavorings containing diacetyl. Morgan DL, et. It would seem that people that vape these flavors are welcoming irreversible lung diseases?
