[11] Diacetyl is present in some chardonnays known as "butter bombs", although there is a trend back toward the more traditional French styles. They found the coated PFAS paper products increased the PFAS blood serum levels of people who habitually consumed microwave popcorn and restaurant fast food versus cooked meals prepared from grocery store products. 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. Approximately 4,700 PFAS are available in the global market. Shouldnt consumers be aware of this potential health risk? Microwave popcorn:It contains diacetyl. This work provides a baseline qualitative and quantitative characterization of diacetyl and related compounds in a common GRAS additive, SDL, and some foods that contain SDL.

The FDA has found that e-cigarettes can contain chemicals and other substances that are potentially harmful to users, including nicotine, diacetyl, and formaldehyde. Recent investigations indicate this method is adversely affected by humidity, resulting in an underestimation of true concentrations. Several efforts are underway to investigate exposures, improve sampling methods, evaluate engineering controls, use animal toxicology models to study a range of flavorings and determine how lung injury occurs, disseminate important public health information, and determine appropriate steps to help safeguard workers health. Although it occurs naturally in some foods, most of the diacetyl in the human diet is artificially manufactured and used to flavor processed food products.
