PFAS, PFOA, and Teflon - these terms are increasingly appearing in the news when it comes to health, environment, and cooking. Many people know that these substances are found in non-stick pans, but what exactly are they, why are they harmful, and how can you avoid them? Fortunately, sustainable and safe alternatives exist, such as stainless steel pans and stainless steel cookware, with which you can cook consciously and healthily.
✔ What are PFAS and PFOA?
PFAS (poly- and perfluoroalkyl substances) are a large group of man-made chemicals that are water, grease, and dirt repellent. They are often used in coatings for pans, packaging, and textiles.
✔ PFOA – one of the best-known PFAS, formerly widely used in Teflon coatings. Now banned in many countries due to proven harmful effects.
✔ PFAS in general – they are hardly broken down in the environment and accumulate in humans and animals. That's why they are also called “forever chemicals”.
✦ Why are they harmful?
Research shows that long-term exposure to PFAS can lead to health problems:
✦ Hormonal disruption.
✦ Reduced fertility.
✦ Increased risk of certain types of cancer.
✦ Accumulation in liver, kidneys, and blood.
Because PFAS do not break down, they remain present in the body and in nature for years.
➤ What exactly is Teflon?
Teflon is the brand name for PTFE (polytetrafluoroethylene), a non-stick coating often used in frying pans. Although Teflon itself can be stable, risks mainly arise when:
➤ The pan is heated too much (above approx. 260°C).
➤ Scratches or wear occur, causing the coating to detach.
➤ Older pans still contain PFOA, which is now banned.
✔ How can you avoid PFAS and Teflon?
✔ Choose stainless steel pans or cast iron – both contain no harmful coatings.
✔ Avoid pans with unclear non-stick coatings.
✔ Use wooden or stainless steel spatulas so you don't scratch pans.
✔ Store food in glass or stainless steel, not in plastic with coatings.
✔ Look for labels like “PFAS-free” or “PFOA-free” when purchasing.
Conclusion
PFAS and PFOA are persistent chemicals that pose risks to both health and the environment. Teflon pans with non-stick coatings can contribute to exposure, especially with wear or overheating. Fortunately, safe and sustainable alternatives exist. With stainless steel pans, you can cook without harmful substances, sustainably and healthily - and directly contribute to a plastic-free, PFAS-free kitchen.
