Excerpt: Most of the time, when you order fast food, you know exactly what you're getting: an inexpensive meal that tastes great but is probably loaded with fat, cholesterol and sodium.
But it turns out that the packaging your food comes in could also have a negative impact on your health, according to a report published Wednesday in the journal Environmental Science & Technology Letters.
The report found fluorinated chemicals in one-third of the fast food packaging researchers tested.
These chemicals are favored for their grease-repellent properties.
Along with their use in the fast food industry, fluorinated chemicals -- sometimes called PFASs -- are used "to give water-repellant, stain-resistant, and non-stick properties to consumer products such as furniture, carpets, outdoor gear, clothing, cosmetics (and) cookware," according to a news release that accompanied the report.
