What Is PFAS and Why You Should Avoid It in Your Cookware
November 8, 2025 — Jan Wilms
Most kitchens in the UK contain something the people cooking with it have never heard of: PFAS. They're a family of chemicals used to make pans non-stick, jackets waterproof, and food packaging grease-resistant.
They're also linked to cancer, hormone disruption, immune problems, and developmental issues in children. And once they enter your body, or the environment, they don't leave. Scientists call them "forever chemicals" for a reason.
If you cook on a non-stick pan, there's a real chance you're being exposed every single day.
This guide breaks down what PFAS actually are, where they hide in your cookware, what they do to your health, and what you can use instead.
What does PFAS stand for?
PFAS stands for per- and polyfluoroalkyl substances. It's not one chemical. It's a family of more than 14,000 different synthetic chemicals, all built around an extremely strong carbon-fluorine bond.
That bond is the reason PFAS exist. It's also the reason they're a problem.
The carbon-fluorine bond is one of the strongest in chemistry. It doesn't break down in heat. It doesn't break down in water. It doesn't break down in soil. It doesn't break down in your body.
PFAS were first developed in the 1940s. By the 1960s, they were everywhere. Today they're found in:
- Non-stick cookware (Teflon, ceramic-coated pans, "PTFE-free" pans that contain other PFAS variants)
- Food packaging (microwave popcorn bags, fast food wrappers, pizza boxes)
- Waterproof clothing and shoes
- Stain-resistant carpets and furniture
- Cosmetics, dental floss, and even toilet paper
- Fire-fighting foam used at airports and military bases
The result: PFAS are now in the blood of nearly every human being on the planet. A 2022 study from the U.S. Centers for Disease Control found PFAS in 97% of Americans tested. UK studies show similar numbers.
How PFAS get into your food
This is the part most people don't realise. You don't have to scratch a non-stick pan for PFAS to end up in your food. They migrate at normal cooking temperatures.
When a non-stick pan is heated above 260°C, the coating starts releasing fumes. At that temperature, those fumes can kill pet birds within hours. There's even a name for it among bird owners: "Teflon flu."
But the bigger problem is what happens at lower, normal cooking temperatures. Studies have found that non-stick coatings shed microscopic particles into food during regular use. A single scratched pan can release millions of plastic particles into a meal.
Some manufacturers have replaced PFOA (one banned PFAS chemical) with newer PFAS variants like GenX, marketed as "safer." Independent research has since shown GenX causes similar health problems. The pattern repeats: ban one chemical, swap it for a near-identical one with a different name, keep selling.
The "PFOA-free" or "PTFE-free" labels you see on cookware today often mean nothing. They confirm one specific PFAS isn't there. They don't confirm the pan is PFAS-free.
What PFAS do to your body
PFAS accumulate. Once they enter your bloodstream, your body has no way to remove them efficiently. They build up over years and decades, and the science on what they do is now alarmingly clear.
Documented health effects from PFAS exposure include:
- Increased risk of testicular and kidney cancer
- Decreased fertility and high blood pressure during pregnancy
- Developmental delays and lower birth weight in children
- Hormonal disruption affecting thyroid function
- Reduced vaccine response in children
- Increased cholesterol levels
- Liver damage
- Weakened immune system
The U.S. Environmental Protection Agency has set the safe limit for PFAS in drinking water at 4 parts per trillion. To put that in perspective, that's the equivalent of about four drops of water in twenty Olympic-sized swimming pools. The chemicals are that potent.
In 2023, the European Chemicals Agency proposed a near-complete ban on PFAS across the EU and UK. The proposal explicitly listed cookware as a high-priority category. Manufacturers are fighting it hard. The reason is simple: there's no profit margin in selling pans that last forever.
The problem with "ceramic" non-stick
When people learn about PFAS, the next question is usually: "What about ceramic non-stick pans?"
Ceramic-coated pans are marketed as the safe alternative. The reality is more complicated.
Most "ceramic" cookware uses a sol-gel coating made of silicon dioxide. It's PFAS-free in the strictest sense. But there are real problems:
- The coating wears out within 6 to 18 months of normal use
- Once the coating cracks, the pan is essentially scrap metal
- Many ceramic pans have an aluminum core, which can leach into food once the coating breaks down
- Some cheaper "ceramic" pans still contain PFAS as a binding agent in the coating
You're not buying a lifetime piece of cookware. You're buying a consumable.
What actually works: solid metal cookware
The only truly long-term solution is cookware made of solid, non-coated metal. There are three real options.
Stainless steel. Durable and safe, but reactive with acidic foods, prone to sticking, and requires technique to cook with.
Cast iron. Excellent heat retention, develops natural non-stick properties when seasoned, but heavy, requires maintenance, and reacts with tomato-based dishes.
Titanium. The newest serious option in home cookware. Naturally non-reactive, won't leach into food, lighter than cast iron, more non-stick than stainless steel, and the same metal used for medical implants because the body doesn't reject it.
Titanium has been used in surgical implants for over fifty years for one specific reason: it's biocompatible. It doesn't break down, doesn't react with bodily fluids, and doesn't trigger immune responses. The same property that makes it safe inside the human body makes it safe in direct contact with food.
This is the principle behind Titanova cookware. The cooking surface is pure Grade 1 titanium, the same medical-grade titanium used in implants. There are no coatings to chip, no chemicals to leach, and no PFAS of any kind. Underneath the titanium cooking surface, a multi-layer construction provides even heat distribution and induction compatibility.
A pan you can cook with for the rest of your life. Without wondering what's coming off it into your food.
What to do next
If you're using non-stick cookware and you want to reduce your PFAS exposure, you don't need to throw everything out tomorrow. Start here:
- Stop using any non-stick pan that's scratched, chipped, or has visible wear
- Never preheat an empty non-stick pan
- Avoid cooking at high heat on non-stick surfaces
- Replace your most-used pan first (usually a frying pan) with a non-coated alternative
- Read ingredient lists and reject "PFAS-free" claims that only list one chemical
The goal isn't perfection. It's reducing daily exposure on the surfaces you use the most.
