Yes, PFOA is heavily restricted and effectively phased out in the US. While it was voluntarily phased out of domestic production by major chemical companies starting in 2006, regulatory agencies have tightened enforcement.
For example, PFOA and some closely related chemicals (such as PFOS) are now no longer made in the US, although they are still made in some other countries and could potentially reach US consumers in certain types of products. Another potential concern is that other PFAS are now in use.
Consumer studies and independent laboratory testing have found that Ziploc brand bags do not contain detectable levels of PFAS ("forever chemicals").
Concerns About PFAS
You might have heard about PFAS, a group of chemicals often used in the production of non-stick cookware. However, most parchment paper does not contain PFAS.
Teflon is a type of PTFE. PFOA: A PFAS previously used in the production of PTFE coatings. It was phased out in the U.S. by 2014 due to health concerns.
The healthiest, non-toxic pans are free of PFAS, PFOA, lead, and cadmium. The safest materials for everyday cooking are cast iron, carbon steel, stainless steel, and 100% pure ceramic or ceramic-coated aluminum.
While there is no immediate medical treatment or magic pill to "flush" PFAS out overnight, your body eliminates them naturally over time through bodily functions like urination, sweating, and blood loss (such as menstruation).
Yes, parchment paper is generally considered safer and healthier than aluminum foil. While foil can leach small amounts of aluminum into food—especially at high temperatures or with acidic ingredients like tomatoes and citrus—parchment paper is non-reactive and does not leach chemicals.
Common types of PFAS found in cookware may be identified as PTFE, PFOA, PFOS, and GenX. This may not be clearly identifiable with some cookware brands, so it is important to consult the manufacturer to obtain this information if not easy to find on the packaging or owner's manual.
Although parchment never stopped being used (primarily for governmental documents and diplomas) it had ceased to be a primary choice for artists' supports by the end of the 15th century Renaissance. This was partly due to its expense and partly due to its unusual working properties.
Does Chick-fil-A's packaging contain PFAS? Products with oil and grease resistant coatings containing PFAS were fully phased out chainwide in the summer of 2022.
You don't need to throw them all away at once. It's best to sort through your stash and replace them gradually with safer options like glass or stainless steel. Discard plastic containers only if they show visible signs of wear.
PFAS are generally considered more dangerous than microplastics. While both are widespread "forever pollutants," PFAS are toxic at extremely low levels and are definitively linked to severe, confirmed health issues. Microplastics are physically invasive, but their direct health effects on humans are still being studied.
Hawaii is widely considered the cleanest state in the U.S. It consistently takes the #1 spot in national rankings for natural environment, boasting the best air quality (lowest AQI) and cleanest drinking water in the country due to its remote island location and constant ocean breezes.
Seafood, particularly shellfish (clams, crab, oysters) and freshwater fish, consistently tests highest for PFAS. This is closely followed by animal-derived products, processed foods, and items in grease-resistant packaging.
Several popular bottled water brands consistently test at non-detectable levels for "forever chemicals" (PFAS). Reputable studies and water quality testing have identified the following brands as PFAS-free:
The healthiest pans to cook with are made from cast iron, carbon steel, stainless steel, or pure ceramic. These materials are free from toxic synthetic coatings (like PFAS and Teflon) and will not leach harmful chemicals or microplastics into your food when heated.
Drinking water. Drinking water has been identified as a substantial source of PFAS exposure for many populations, particularly those living near contaminated sites.
No, enamel pans do not contain PFAS. Enamel (or porcelain enamel) is essentially a layer of glass melted and fused onto a metal base like cast iron or steel. Because it is a mineral-based material, it is completely free of synthetic non-stick chemicals like PFAS, PTFE (Teflon), and PFOA.
People wrap foil around doorknobs as a viral DIY alarm and visual deterrent. The theory is that if an intruder tries to turn the handle from the outside, the crinkling noise will wake you, or the ripped foil will let you know someone attempted to enter while you were asleep.
Placing cookie dough, biscuit rounds, etc on a sheet pan lined with a piece of parchment paper ensures your final product won't stick. No need to use cooking spray and add extra grease, and clean-up is much easier as you can just throw it away when you're done.
They stopped making true tin foil in the 1940s because aluminum was cheaper, lighter, more durable, and—crucially—did not leave a metallic aftertaste on food. Although true tin foil hasn't been produced for nearly a century, the name "tin foil" stuck around out of habit.
Tap water quality varies significantly across the U.S. based on industrial runoff, aging infrastructure, and chemical treatments. Cities with the worst tap water often feature high levels of contaminants like PFAS, lead, or radioactive byproducts.
Certain dietary fibres and gut bacteria may help remove PFAS, also known as 'forever chemicals', from the body. These findings could pave the way for probiotic and fibre-based nutraceuticals.
When your body struggles to efficiently process and eliminate waste, a buildup of environmental pollutants, chemicals, and byproducts can occur. Common warning signs of this overload often manifest as persistent fatigue, stubborn digestive issues, recurring headaches, and visible skin problems like acne or eczema.
