We love our air fryers. They are super convenient and so much faster than the conventional oven. Our food can be prepared in minutes without the use of a harmful microwave.
Air fryers are a great way to cook food with less oil or grease. They use less energy, and the food comes out crispy and delicious. But what are the health benefits of air frying?

Cooking volume × material priority × counter space = your toxin-free match.
Why your cookware is part of the bigger toxic-load picture
PFAS chemicals from non-stick coatings are documented endocrine disruptors. They bioaccumulate in fat tissue, persist for years, and combine with everything else competing for your body’s detox bandwidth – plastics, pesticides, processed-food additives, indoor air pollutants. A single Teflon air fryer might add only a tiny burden. But it stacks with everything else – and the cumulative load is what determines whether your body can keep up with detoxification or starts slipping behind.
The Toxic Load Assessment maps your total burden across the 6 major exposure categories (cookware, water, personal care, food, indoor air, EMF) – so the air fryer swap is part of a coordinated reduction, not a one-off feel-good change.
Take the Toxic Load Assessment →The straight answer: do air fryers cause cancer?
The short answer is: air fryers themselves do not cause cancer, but two factors associated with how air fryers are made and used CAN create cancer-relevant exposures. Cancer risk from air-fryer use comes from (1) the non-stick coating material on most consumer air fryers (PTFE / PFAS chemicals can release particles when cooking surfaces wear down or overheat past ~500°F) and (2) acrylamide formation – a probable human carcinogen that forms when carbohydrate-rich foods are cooked at high temperatures, regardless of whether the cooking happens in an air fryer, oven, or skillet. The fix is choosing a stainless-interior air fryer + keeping cooking temps under 380°F for starchy foods + avoiding burned/blackened spots.
Most people in detox or chronic-symptom work eventually hit the same problem: the same symptoms — fatigue, brain fog, gut issues, poor sleep — can come from completely different root causes, and the wrong protocol can run for months before that becomes obvious. The 2-minute What's Draining Your Brain Tool sorts you into one of four toxic load types so the next thing you try has a real chance of actually working.
PFAS / PTFE: what the research actually shows
PFAS (per- and polyfluoroalkyl substances) are a chemical family that includes PTFE – the slippery polymer in Teflon-style non-stick coatings on most consumer air fryers. PFAS bioaccumulate in human tissue, cross the placenta, and are linked to immune dysfunction, thyroid disorders, low birth weight, preeclampsia, and (per ongoing studies) certain cancers. They are detectable in 98%+ of Americans tested via blood serum. Whether the contribution from a single air fryer is meaningful is hard to isolate – but the conservative move is to eliminate the source you control. Switching to a 304 stainless interior is one of the cheapest, easiest swaps in the kitchen.
Acrylamide: the real elephant in the air fryer
Per the 2020 review in Archives of Microbiology, acrylamide is classified as a probable human carcinogen. It forms when high-carbohydrate foods (potatoes, bread, crackers) are heated above approximately 248°F via the Maillard reaction. The browning chemistry that makes french fries delicious also creates acrylamide – and air fryers, by design, achieve high-temperature browning. The amount you ingest from typical air-fried foods is significantly less than from deep-frying or industrial baking, but more than from steaming or boiling. Cancer-conscious cooking: avoid blackening starchy foods, keep cooking temps under 380°F when possible, and pair frequent air-frying with antioxidant-rich vegetables that help the body neutralize acrylamide metabolites.
According to one study, air-fried foods contain less bad fat than foods prepared using traditional deep-frying methods.
Air frying also lessens the exposure to harmful chemicals and other toxins that can be found in the oils and fats used for deep-frying. All in all, using an air fryer can be a healthier way to cook your food.
BUT…
#1 consideration to make air frying safer
Check that your air fryer interior is not coated in Teflon
Air fryers are great, but they are not without some concern.
There are a few factors to be aware of as a caveat to air fryers being a completely healthy way to cook.
If your air fryer basket or interior is coated with Teflon, this is a concern. There are a number of negative health issues related to Teflon. These include cancer, hormone disruption, and environmental toxicity.
Cancer: Studies have shown that exposure to polytetrafluoroethylene (PTFE), the main component of Teflon, can increase the risk of developing cancer. PTFE is released when products made with it are heated or damaged. It has been linked to cancers such as ovarian cancer and non-Hodgkin’s lymphoma.
Hormone Disruption: Teflon particles have been found to impair estrogen function in laboratory animals. This could lead to increased rates of breast cancer and other reproductive problems down the line. In addition, studies have suggested that exposure to PFCs can disrupt the hormones that control weight perception and appetite regulation in humans.
Environmental toxicity: The manufacture of Teflon involves chemical processes that release harmful pollutants into the atmosphere. These pollutants can contaminate water supplies, contribute to climate change, and cause adverse health effects in people who live near factories manufacturing these products.
#2 consideration to make air frying safer
Use a stainless-steel air fryer
The best air fryers are those that are made of stainless steel on the interior, without non-stick coatings on top of the stainless steel.
If your air fryer is coated in Teflon on the interior, or the basket is coated in Teflon, you may want to consider replacing it with one that is free of Teflon like this one:

Air fryers still produce acrylamides, found in crispy foods
It is important to be aware of the risks whenever you eat crispy foods. The amount of oil used produces more or less acrylamides, not zero.
Research behind air fryer cancer concerns
- Muneer F, et al. (2020). Microbial L-asparaginase: purification, characterization and applications. Archives of Microbiology, 202(5):967-981. [DOI]L-asparaginase is now used industrially to reduce acrylamide formation in carbohydrate-rich foods cooked at high temperatures – confirming acrylamide as a probable human carcinogen and a major target for food-safety research. Air-fried starchy foods produce more acrylamide than steamed/boiled equivalents.
- Szilagyi JT, et al. (2020). Per- and polyfluoroalkyl substances differentially inhibit placental trophoblast migration and invasion in vitro. Toxicological Sciences, 175(2):210-219. [DOI]PFAS chemicals (the family that includes PTFE / Teflon) cross the placenta, alter cell migration, and are linked to low birth weight and preeclampsia. The conservative move with consumer cookware: eliminate sources you control by choosing stainless or ceramic-only interiors.
The European Food Safety Authority has classified acrylamide as a “possible human carcinogen.” Acrylamides are found in all crispy, fried foods like potato chips, fried chicken, French fries, etc.
People who consume more than two servings of crispy foods made with oil per week are more likely to develop cancerous tumors than those who do not consume these types of foods on a regular basis.
3 ways to avoid eating excessive amounts of acrylamides
The best way to avoid consuming too many fried, crispy foods containing acrylamide? Follow these simple tips:
- Avoid eating deep-fried food altogether; instead, try healthier options like grilled or baked goods.
- Cook your food at low temperatures to reduce the amount of time it spends cooking at high temperatures.
- Refrain from adding excessive oil during air-frying. Doing so may increase the risk of inflammation and cancer.
Air fryers are better than deep frying
There are a few ways in which air frying could affect the nutritional content of food, create acrylamides, and impact your cancer risk.
Air fryers use less oil, and this may limit the amount of acrylamide, which are chemicals that are classified as group 2A carcinogens, that is produced.
Concluding Thoughts
Most people know that eating fried foods is not healthy for us. The air fryer appeared to remove that risk for a brief moment! We all embrace the wonders of the air fryer.
Though the air fryer is better than deep frying, we need to use an air fryer that does not have a Teflon interior and be aware that cancer-causing acrylamides are being produced when we make crispy food. Though using an air fryer is better than using a deep fryer, staying away from crispy foods made with oil as much as we can is the healthiest bet. Two meals a week in the air fryer that are made with oil to crisp them seem to be the limit if we cannot avoid that fried food taste.
