A bunch of smart scientists sampled 400 fast food wrappers and boxes and found that many of the big fast food chains have used unhealthy fluorinated chemicals in their packaging. The group published its findings in Environmental Science & Technology Letters. Their conclusion helps to explain how we all have โfluorinated chemicalsโ in our blood.

Have you ever noticed that the food you buy at McDonaldโs or Burger King doesnโt glom onto the food wrappers the way your homemade meals do? I hadnโt, either. But the big brains in consumer packaging and the food industry did think about that problem and came up with a brilliant โno-food-stickageโ idea: adding non-stick repellent to the wrapper.
But the non-stick concept relies on a nasty set of chemicals that โ you guessed it โ are not good for humans. The fluorinated chemicals, found in just about every Americanโs blood, make nonstick, waterproofing and stain-proofing applications do their thing.
Fluorinated chemicals can be found in so many consumer products, including furniture, carpets, outdoor gear, clothing, cosmetics, cookware and even food packaging materials. The nasty downside to the widespread use of these materials is that people are getting quite sick from this chemical class.

Fluorinated chemicals are scientifically linked to kidney and testicular cancer, elevated cholesterol, decreased fertility, thyroid problems and changes in hormone functioning in adults, as well as adverse developmental effects and decreased immune response in children. If youโre curious and want a deeper dive into the impact of fluorinated chemicals, check out Oregon Stateโs Dr. Jennifer Fieldโs webinar. This is serious stuff.
Dr. Arlene Blum, my favorite scientist hero, asks the big question: โWhy are we putting any fluorinated materials into contact with food?โ Blum, of UC Berkeley and the Green Science Policy Institute, is an author of the study and the lady who, after 30 long years, finally got the cancer-causing and ineffective flame retardants out of upholstery and kidsโ products. โGiven the potential for harm, we must ask if the convenience of water and grease resistance is worth risking our health,โ said Blum.
Dr. Blumโs Green Policy Institute offers easy steps to take to reduce your fluorinated chemical exposure:
- Avoid products that are oil-repellent or stain-resistant.
- Only purchase waterproof gear when you really need it.
- Avoid cosmetics with PTFE or any word containing โperfluorโ or โpolyfluorโ on their ingredients list.
- Replace your Teflon nonstick cookware with cast iron, glass or ceramic.
- Avoid microwave popcorn and greasy foods wrapped in paper.
- Tell retailers and manufacturers you want products without fluorinated chemicals.
Companies like IKEA, Crate & Barrel and Levi Strauss are committed to phasing out highly fluorinated chemicals. Some apparel brands have joined Greenpeaceโs Detox campaign, and fast food chains have removed them from food packaging as a result of EWGโs action.
This study and all the articles that weโve published below in Beneath the Surface hit on one key point: Our modern world is marinating in unregulated and untested chemicals. The chemicals are getting into our familiesโ bodies and are making people sick. Itโs really up to us to prioritize asking two simple questions: โWhatโs in this product?โ and, โShould I be careful about this product for my familyโs sake?โ
The scientific journal Epidemiology (my fav) published a study: โPrevention of Development Neurotoxicity.โ This phrase, put another way, means stopping toxins from getting into babiesโ nervous systems.
A large group of brilliant scientists stated that the United Statesโ and other world governmentsโ regulatory systems are โfundamentally broken.โ They suggested a plan to fix it so that pregnant women can reduce adverse toxins in their babiesโ central nervous system development. And we wonder why rates of chronic health issues are increasing?
This article is part of the Beneath the Surface series: โWhatโs in Everyday Consumer Products?โ Articles in this series will examine the prevalence of synthetic chemicals in everyday products and the consequences of their use to our health and our environment. Some other work from the series:
