Using them can also decrease exposures to the thousands of flavoring chemicals that have not been studied for toxicity after inhalation and do not have occupational exposure limits. Add to List Although consumers are less likely to inhale levels of diacetyl in quantities high enough to cause lung damage, last year, one such case was reported in a Denver, CO, man. ", Hubbs AF, et al.. "Respiratory toxicologic pathology of inhaled diacetyl in Sprague-Dawley rats. Consuming these Maybe we need to forgo the easy microwave method and go back to using a stove, a pan with a lid and real butter. These findings in conjunction with laboratory experiments providing biological plausibility, meet the standard criteria used to determine causation: that an exposure is the likely cause of specific health effects [Gordis 1996; Hill 1965].7, NIOSH also expressed concern about 2,3-pentanedione based on its structural similarity to diacetyl and animal studies showing that it caused damage in the airways of animals, similar to that caused by diacetyl. How much exposure that people have to diacetyl and other inhaled flavoring chemicals is an important determinant of risk for lung disease. Doru Paul, MD, is triple board-certified in medical oncology, hematology, and internal medicine. 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. Several operations that I have been asked to evaluate involve diacetyl as an ingredient in powder material. It is found in processed foods that contain butter flavoring, such as butter, butter sprays, margarine, shortening, oil, and oil sprays, in addition to processed foods containing butter flavoring. Occupational exposure to diacetyl among workers in microwave popcorn and food-flavoring factories has been linked with respiratory problems and debilitating lung disease. Hubbs AF, et al.. "Respiratory toxicologic pathology of inhaled diacetyl in Sprague-Dawley rats." Even substituting sugar with artificial sweeteners wont help.
