On May 29, 2013 the developmental biologist Bruce Blumberg, University of California at Irvine, U.S. published an article in the lifestyle magazine Men’s Journal pointing to the role of chemical obsogens in widespread obesity. He argues that based on studies of tributyl tin (TBT) and certain diabetes drugs, many of the chemicals used in consumer products, such as personal-care products and food packaging, may lead to increased body weight while the same number of calories is consumed. While he says it is not possible to quantify the role these obsogens play, they might be the missing link in the obesity epidemic.
Blumberg is also active in the green chemistry movement which aims at developing safe alternatives for unsafe chemicals used in consumer products. He argues that these safe alternatives will eventually replace the critical chemicals currently on the market.
