The Hidden Way Fast Food Just Got Worse For Us

Toxins in fast food wrappers leach into your food.

Do you remember hearing all about the dangers of Teflon? Coated with PFOA (a known carcinogen) the non-stick pots that many were using to try to cook more healthfully suddenly became a toxic concern when research about the dangers of the PFOA coating became mainstream news.
As a result millions of home cooks eschewed non-stick pans altogether, choosing instead to cook with good old cast iron, ceramic-coated pans and stainless steel.
Fast forward 10 years and the concern that we all thought was regulated out of existence (many manufacturers voluntarily agreed to remove PFOA from their non-stick formula) has reached the popular media again.
(I should add that there was always concern that the replacements for PFOA – referred to as PFCS or PFAS for short – could be equally toxic, it’s just that he research hadn’t caught up with the compounds.)
But back to the fast food concern…
It’s the fast food wrappers that we now have to worry about.They’re treated with a PFC coating to keep grease and moisture from seeping through and when hot food in placed against the wrappers, some of the chemical compound seeps into the food. Grease and oil makes it especially easy for the chemicals to leach into the food.
In a U.S. study conducted in 2014 and 2015, 40% of food wrappers and packages collected from major fast food restaurants contained some of the chemicals that make up PFCs.
The manufacturers of these compounds say that they’re safe for food contact because the body can eliminate them quickly. But there is independent research that connects PFCs with high cholesterol, obesity, kidney and testicular cancer, abnormal thyroid hormone levels and pregnancy-induced hypertension. Even small doses are harmful.
Children are especially vulnerable because their growing bodies can’t deal as well with toxins, and they’re smaller so the “dose” they may receive from their fast food meal is proportionately larger than it is for an adult.
Non-coated wrappers and packaging are available but how do you know if a package is treated?

Good luck. It isn’t obvious since even compostable packaging could be coated and packaging produced in China can contain chemicals that have been phased out in North America.

So how do you reduce your exposure to these chemicals? 

  • Order fast food less often or not at all and don’t let your kids eat fast food (not always easy if they old enough to go to fast food restaurants on their own). 
  • Another option is to bring your own containers, but since that isn’t common practice around here you might feel a little goofy. 
  • Doing all that you can to reduce the amount of time that your food touches the packaging by eating in at the fast food restaurant my help but there is no research to confirm if that makes a difference. 
  • Don’t order hot, greasy stuff since it’s the grease and oil that makes the chemical leaching more dramatic.

If you’re looking for a reason to kick your fast food habit, this might be it. Just picture that burger and fries with a slick coating of PFCS.

  1. Thanks Bridget, It's unbelievable that we're still fighting this battle. I just read a post about children reaching puberty at younger and younger ages, sometimes as young as 7yrs. There's so much wrong with food distribution and so hard to battle for change with the large corporations.
