Do Air Fryers Give You Cancer? | The Facts on Acrylamide

A warning about air fryers and cancer has circulated online for years. The concern centers on acrylamide, a compound that forms when starchy foods are cooked at high temperatures. It sounds alarming — a popular kitchen appliance linked to a serious disease.

Here’s what the research actually shows. Air fryers themselves are not known to cause cancer. The cooking process inside them does produce acrylamide, which the International Agency for Research on Cancer classifies as a probable human carcinogen. But the levels in air-fried food are generally lower than what you’d get from deep frying, and there are straightforward ways to reduce them further.

What Is Acrylamide and How Does It Form

Acrylamide is a chemical that forms naturally when certain foods are heated above 120°C (250°F). It comes from a reaction between sugars and the amino acid asparagine — compounds found naturally in starchy plant foods like potatoes, bread, and coffee. The FDA notes that acrylamide is not added to food; it is a byproduct of the cooking process itself.

The Maillard reaction is responsible for that golden-brown crust on air-fried french fries or roasted vegetables. This same chemical process produces acrylamide. The darker the food gets, the more acrylamide forms. That’s why the FDA recommends cooking starchy foods to a golden yellow color rather than brown or dark brown.

Acrylamide appears primarily in plant-based foods cooked at high temperatures. Potato products like fries and chips are common sources, along with coffee and grain-based foods like bread and crackers. Boiling and steaming do not reach the temperatures needed for acrylamide formation, which is why those methods produce very little of the compound.

Why This Question Keeps Coming Up

The question keeps surfacing because the science sounds scary on its own. Acrylamide is a probable carcinogen. But context matters — how much you’re exposed to, how often, and what you’re comparing it to all change the picture.

• Acrylamide is not unique to air fryers: Deep frying, baking, roasting, and even toasting bread all produce acrylamide. The compound has been found in common cooked foods for decades, long before air fryers existed.
• The “probable carcinogen” label needs context: IARC Group 2A means there is limited evidence in humans and sufficient evidence in animals. Everyday substances like aloe vera extract and some pickled vegetables carry similar classifications.
• New appliances attract extra scrutiny: The same questions came up about microwaves decades ago. Air fryers intentionally brown food, which makes the acrylamide question more relevant than it would be for a steamer or slow cooker.
• Headlines often miss the nuance: A study about acrylamide in air-fried food gets reported as “air fryers cause cancer” even when the same study found lower levels than deep frying. The comparison is the critical piece that gets left out.

The real question isn’t whether air fryers produce acrylamide — they do, like any high-heat cooking method. The question is whether they produce more or less than the alternatives. That’s where the research provides a much clearer answer.

Air Fryers vs. Deep Fryers: Comparing the Risk

A 2024 peer-reviewed study directly compared acrylamide levels in air-fried and deep-fried potatoes. The air-fried samples contained significantly lower levels of the compound. The study also confirmed that cooking temperature and duration are the main drivers of acrylamide formation — not the type of appliance. Verywell Health covers this comparison in its air fryer acrylamide comparison, noting the levels are lower than deep frying but higher than boiling or steaming.

Air fryers typically operate at similar or slightly lower temperatures than deep fryers, and they use a fraction of the oil. Both factors reduce the conditions that create acrylamide. The FDA confirms that lower cooking temperatures can substantially reduce acrylamide formation in starchy foods.

A separate 2024 study on air-fried lotus root chips identified specific risk factors. Higher temperatures and longer cooking times both increased acrylamide levels. The takeaway is that technique and doneness matter more than which appliance you choose.

The table shows that air fryers offer more control over browning and use less oil. Both factors contribute to lower acrylamide formation when you use the appliance thoughtfully and keep an eye on doneness.

How to Reduce Acrylamide When Air Frying

The FDA offers several practical strategies to reduce acrylamide formation. These work with any cooking method, including air frying. None require special equipment or hard-to-find ingredients.

1. Cook to golden, not brown: The FDA recommends aiming for a golden yellow color rather than brown or dark brown. The darker the food, the more acrylamide it contains. This is the single most effective step you can take.
2. Soak potatoes before cooking: Soaking raw potato slices in water for 15–30 minutes before air frying reduces the precursor sugars and amino acids that form acrylamide. Drain and pat them dry before adding oil and seasoning.
3. Don’t overcrowd the basket: Air fryers rely on hot air circulation. Overcrowding leads to uneven cooking, which encourages you to cook longer or at higher temperatures. Both adjustments increase acrylamide formation.
4. Store potatoes in a cool, dark place: Avoid refrigerating potatoes. Cold temperatures can convert starches into reducing sugars, which raises the acrylamide potential during cooking.

These steps don’t eliminate acrylamide entirely, but they can reduce it meaningfully. Combined with the fact that air frying already produces less than deep frying, they make a noticeable difference for regular air fryer users who cook starchy foods frequently.

What About Other Compounds in Air-Fried Food

Acrylamide isn’t the only compound worth paying attention to. Air frying fatty fish, for example, can increase cholesterol oxidation products (COPs), which are linked to heart disease risk. Cleveland Clinic covers this in its review of air fryer cholesterol oxidation products, noting that very high heat on fatty fish produces these compounds. Cooking fish at moderate temperatures and avoiding prolonged heating helps minimize them.

Over-crisping food until it’s very dark or charred can also produce heterocyclic amines (HCAs). These compounds form when meat is cooked at high temperatures and are also classified as probable carcinogens. The risk is highest with blackened or burnt food, regardless of the cooking method.

The overall picture is reassuring for most air fryer users. Air frying compares favorably to deep frying across multiple measures — less acrylamide, less oil absorption, fewer calories. Cleveland Clinic’s expert review concludes that air frying is a healthier cooking option overall, especially when you avoid burning food and maintain moderate temperatures throughout the cooking process.

The Bottom Line

Air fryers themselves do not cause cancer. The cooking process can produce acrylamide, but levels are generally lower than what deep frying produces. Cooking to a golden color, soaking potatoes, and avoiding burnt food all help keep exposure moderate.

For most people, pulling air-fried food when it’s light golden rather than dark brown keeps acrylamide at levels well below those typical of deep frying.
