You might be particularly worried about whether using an air fryer can cause cancer. These are valid concerns, and it’s important to understand the scientific evidence behind them. In this blog, we’ll talk about all aspects of air fryers and cancer.

We’ll show you the latest research and help you make a decision about how using an air fryer might affect your health.

Investigating Claims of a Link between Air Fryers and Cancer

Air fryers have become increasingly popular in recent years, as they offer a healthier alternative to traditional deep frying. However, there have been claims that using an air fryer could increase the risk of developing cancer. So, is there any truth to these claims?

What Research Says about Air Fryers and Cancer

Studies have revealed that heating oils for extended periods at a high temperature can result in the formation of harmful polar molecules like polymers, dimers, free fatty acids, and acrylamide. [1] These harmful substances have the potential to alter human metabolism and raise cancer risk. [2] Similar to deep fat frying, but with less oil and polar chemicals, the air-frying method employs high heat to cook food.

A study by the University of California found that air fryers emit ionizing radiation, which has the potential to cause cancer. Air fryers generate a type of radiation that can be harmful to human health, even if the study did not discover a direct connection between air fryers and cancer. So, they advised that it is best to use air fryers carefully and limit how often you use them. [3]

The Hong Kong Consumer Association did another study to let people know that using oil-free fryers could be bad for their health. The association found that half of the 12 brands tested produced high levels of carcinogenic acrylamide, which is 13 times more than the allowed limit according to EU standards. [4]

According to a study, heating food in air fryers at high temperatures can lead to the production of chemicals like acrylamide and heterocyclic amines (HCAs) that have been linked to cancer. It’s important to remember that air-fried food still contains only small amounts of acrylamide and HCAs, and there is thought to be no overall risk of cancer from using air fryers.

So, Air Fryers Really Cause Cancer?

A rising number of people are worried that air fryers may cause cancer because they produce acrylamide. This claim has been backed up on social media and in online forums, making many people worry about how safe air fryers are. Most of the time, the idea that air fryer cause cancer is based on personal experience or opinion, not on facts.

It’s crucial to keep in mind that scientific evidence does not back up this claim. Although acrylamide has been linked to an elevated risk of cancer in animal studies, there is currently no proof that air fryers cause cancer in people. [5]

The International Agency for Research on Cancer (IARC) has put acrylamide in Group 2A of cancer-causing substances. [6] This grouping is based on the results of many scientific studies that show a possible link between eating acrylamide and getting cancer. To fully understand how dangerous, it is to eat acrylamide, more research is needed because the evidence is still not enough.

Several scientific studies, including ones published in 2018 and 2019 in the European Journal of Cancer Prevention and the International Journal of Cancer, back up the claim that air fryer causes cancer. These studies found that eating fried foods doesn’t increase a man’s risk of getting prostate cancer. [7]

Several scientific studies on relation between cancer and acrylamide reports no link between cancer and acrylamide intake. [8, 9, 10]

Another study looked into amount of acrylamide formation in air frying and compared it with deep frying and found out that air fried food resulted in more nutrient, less acrylamide and consumed less oil compared to deep frying. [11]

The assertion that air fryers may cause cancer seems to have its roots in 2015. The study was published in the journal Food Chemistry. It looked at the levels of acrylamide in several dishes that were cooked both traditionally and in an air fryer. Although the study discovered that some air-fried items had higher acrylamide levels, the amounts were still below safe ranges and did not represent a serious health concern.

So, What Causes Cancer then?

Genetic mutations, environmental factors, and lifestyle choices are just a few of the complex factors that can cause cancer. [12] Consuming processed and red meats, foods high in saturated and trans fats, and foods low in fruits and vegetables can all increase your risk of cancer. [13]

When food is cooked or grilled at high temperatures, harmful compounds such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) can form. [14] Another common compound that can form during high-temperature cooking or frying of food is acrylamide, which is considered a carcinogen.

So, what is this Chemical called Acrylamide?

While doing research on if air fryer causes cancer, i came across this video that explains the relation of acrylamide in air fryer.

Acrylamide is a chemical compound characterized as a water-soluble crystalline solid, C3H5NO, that forms during high-temperature cooking processes from the reaction between sugars and asparagine in starchy foods, and it has been classified as a potential human carcinogen. [15, 16]

Acrylamide in Air Fryer

Although air fryers can cut down on acrylamide formation by moving hot air and using less oil, it is important to remember that they may not be able to stop it completely. Choosing ingredients with less acrylamide, pre-treating some foods, cutting food into even sizes, cooking at lower temperatures, cooking for less time, and trying with different coatings are all good ways to reduce acrylamide.

Is there a safe level of acrylamide?

Researchers are still trying to figure out how much acrylamide is safe to be around. As a precaution, governing agencies suggest limiting its use because it might cause cancer. Even though there isn’t a set safe amount, using healthy cooking methods and staying up to date on scientific findings can help reduce exposure.

Factors that Contribute to Acrylamide Formation

#1 High Cooking Temperatures

Acrylamide is formed when food is cooked at high temperatures, especially above 120°C (248°F). [17, 18]

#2 Longer Cooking Times

The chances of acrylamide forming go up with longer cooking times. [18]

#3 Browning and crisping

Foods that are deep-fried or roasted, which brown and crisp the food, are more likely to make acrylamide.

#4 Starch Content

Foods like potatoes and grains that have a lot of starch are more likely to turn into acrylamide. [19]

#5 Sugars and Amino Acids

The presence of sugars (glucose and fructose) and certain amino acids (asparagine) in food products helps acrylamide form. [20]

#6 Storage and Shelf Life

Some foods can make more acrylamide if they are kept for a long time, especially at room temperature. [21]

The type of cooking utensil

The type of cooking utensil used can also influence acrylamide formation. Cooking utensils made of nonstick materials, such as Teflon, may raise the risk of acrylamide formation.

The Science Behind Air Fryers

This video explains, how air fryer work?

Popular kitchen appliances called air fryers to cook food by frying it in hot air, giving it a crispy texture akin to traditional frying techniques. The cooking process in air fryers works by moving hot air around the food to cook it and give it a crispy surface. Using a heating element and a fan to move the hot air around the food is accomplished.

Air frying is a healthier alternative to regular frying because it uses far less oil and fat. This is so that food doesn’t end up with a high calorie and fat content from typical frying techniques, which entail putting food in hot oil. Contrarily, air frying uses little to no oil at all, thus lowering the number of calories and fat in the food.

Air frying has the additional advantage of producing less acrylamide, a chemical that can occur when starchy foods are cooked at high temperatures, such as when deep frying. Even though the data on people isn’t clear, studies on animals have linked acrylamide to a higher risk of cancer. By using hot air instead of hot oil, air fryers reduce the amount of acrylamide by a lot.

How to Choose a Safe Air Fryer: Tips for Avoiding Toxic Chemicals in Air Fryers

There are many popular air fryers on the market with per- and polyfluoroalkyl substances (PFAS) non-stick coatings, which can be hazardous to one’s health. As a result, it can be difficult to distinguish between air fryers that are safe and those that are not. While air fryers that are certified as PFAS-free are safe to use, chemicals such as polytetrafluoroethylene (PTFE), perfluorooctanoic acid (PFOA), and PFAS are known to have serious health consequences.

There are a few steps you can take to prevent purchasing an air fryer that contains harmful chemicals. The first thing to remember is to avoid air fryers that include PTFE, PFOA, and perfluorooctanesulfonic acid (PFOS). GenX, a substance that the Environmental Protection Agency has determined to be dangerous, has been used by some producers in place of PFOA.

It is advised to choose an air fryer that is PFOS- and PFOA-free and has been approved by the US Food and Drug Administration (FDA). By doing this, you can be sure that the appliance you are buying is really safe to use. In addition, there are lots of little air fryers on the market that provide secure cooking alternatives, letting you make healthy food without worrying.

Are air fryers energy-efficient?
