Popcorn ingredient, lies linked to poor mental health

DIACETYL, a flavoring used to produce the buttery flavor and aroma of microwave popcorn and other food, may be linked to Alzheimer's, United States researchers say.Robert Vince, director of the Center for Drug Design at the University of Minnesota, and colleagues Swati More and Ashish Vartak said diacetyl has been the focus of research recently because it is linked to respiratory and other problems in workers at microwave popcorn and food-flavoring factories.In addition to microwave popcorn, diacetyl is used in margarines, snack foods, candy, baked goods, pet foods and other products such as beer or some chardonnay wine, the researchers said.Vince's team said it realised that diacetyl has an architecture similar to a substance that makes beta-amyloid proteins clump together in the brain ' this clumping is the hallmark of Alzheimer's disease.The study, published in the journal Chemical Research in Toxicology, found diacetyl increased the level of beta-amyloid clumping. In addition, the study found at real-world occupational exposure levels, diacetyl also enhanced beta-amyloid's toxic effects on nerve cells growing in the laboratory.
