You might think the biggest risk of takeout is extra calories, but research shows your food’s packaging could be even more concerning. A new study links frequent exposure to plastic takeout containers with a higher risk of heart failure.

The researchers also suggest that the plastic chemical exposure itself may lead to heart muscle damage, along with inflammation and oxidative stress, an imbalance of free radicals and antioxidants in your body that may lead to cell damage. All of these are “closely tied to cardiovascular disease,” the researchers wrote.
