Food Packaging Linked to Weight Gain

"The takeaway message is that any ordinary plastic product might have a mix of substances that could contribute to excess weight or lead to obesity," Martin Wagner, PhD, associate professor in NTNU's

That's especially true since these chemicals don't always stay in the material, but may leach out into food and drink, where they might then be consumed."

The extent of how much plastic packaging might contribute to weight gain is unknown, Wagner adds,so that makes it more challenging to know whether you should veer away from this packaging altogether.

At the very least, Wagner said, it's helpful to limit plastic use when possible, especially with those two main culprits, bisphenols and phthalates. That's true for takeout food as well as groceries,

according to another recent studypublished in the Journal of Exposure Science & Environmental Epidemiology.In that research,samples of fast food from six chain restaurants revealed that many wrappers

and containers contained phthalates, with the highest concentrations in meat-based items like burritos and hamburgers.Plus, it's not just food that might be an issue.

According to the Centers for Disease Control, these chemicals are used in hundreds of products, including personal care items like shampoos and soap. 

Although you may not be able to avoid these chemicals completely, being aware of them could be helpful for cutting down at least a bit, says Wagner. 

That could give your metabolism the break it needs, and maybe even prevent some weight gain along the way.
