Chemical obesogens in the food supply may be contributing to the obesity epidemic.
Obesity-Causing Pollutants in Food
Below is an approximation of this video’s audio content. To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video.
The dramatic rise in obesity has been blamed on overeating and inactivity—but might it be something more? I talked about the “chicken obesity virus.” Scientists are now identifying industrial chemical pollutants released into the environment in the last few decades that can disrupt our metabolism and predispose us to obesity. These pollutants have been called obesogens.
The existence of chemical obesogens suggests that the prevailing paradigm, which holds that diet and decreased physical activity alone are the causative triggers for the burgeoning epidemic of obesity, should be reassessed—which is what scientists are doing now.
The focus has been on these organotin compounds. Basically they turn preadipocytes—pre-fat cells— into fat cells. How are we exposed? Through our diet.
Where are these obesogens found the most? Beans, dairy, fish, fruit, grains, meat, nuts, or veggies? There are actually some in conventionally grown fruits and veggies, because some of these chemicals are used as fungicides, but the #1 dietary source is fish.
Again, you hear the word pollutant, you think fish, as oceans have become humanity’s sewers. Everything eventually flows down into the sea.
Please consider volunteering to help out on the site.

Comment Etiquette
On NutritionFacts.org, you'll find a vibrant community of nutrition enthusiasts, health professionals, and many knowledgeable users seeking to discover the healthiest diet to eat for themselves and their families. As always, our goal is to foster conversations that are insightful, engaging, and most of all, helpful – from the nutrition beginners to the experts in our community.
To do this we need your help, so here are some basic guidelines to get you started.

We will remove any posts in violation of our rules when we see it, which will, unfortunately, include any nicer comments that may have been made in response.
Be respectful and help out our staff and volunteer health supporters by actively not replying to comments that are breaking the rules. Instead, please flag or report them by submitting a ticket to our help desk. NutritionFacts.org is made up of an incredible staff and many dedicated volunteers that work hard to ensure that the comments section runs smoothly and we spend a great deal of time reading comments from our community members.
