Throughout this article, we will highlight more dangers of air fryers that you may have yet to be aware of to help you stay safe and informed while cooking in your kitchen.

Health Risks of Air Fryers 

To begin, we will explore some of the health risks of air fryers that are largely unknown to many who use them. While you may have read some shocking headlines claiming that air fryers cause cancer, the reality is a bit more complicated. Nevertheless, it is vital to understand the risks that air fryers can pose and how to avoid them.

Acrylamide Formation

One of the major risks of air fryers is acrylamide formation, which occurs when cooking foods at high temperatures. The chemical often develops in starchy foods like potatoes or bread and is created through a reaction between sugars and an amino acid called asparagine when the food is heated above 120°C. 

This is concerning as studies have shown that consumption of high levels of acrylamide can increase the risk of cancer. For the most part, many have no issues when consuming foods that can develop acrylamide, however if you frequently cook starchy foods at high temperatures you are at risk. To reduce acrylamide formation, you can cook your food at lower temperatures, avoid overcooking or burning, and try to eat a balanced diet that includes a variety of cooking methods.

High Cholesterol and Fat Content

It is often stated that air fryers use less oil in the cooking process which makes them inherently healthier than other cooking methods. However, air fryers can still produce high-fat and high-cholesterol foods if not used appropriately. 

One of the main points to consider is that the fat and cholesterol content of the food still depends on what you're cooking. For example, bacon and other fatty meats will still be high in cholesterol despite being cooked in an air fryer. Likewise, convenience foods such as frozen chips and breaded chicken can still contain added oils and unhealthy fats, so cooking them in an air fryer doesn’t make them healthier than when prepared via other cooking methods. 

Dangers of Air Fryers

Understanding the health risks of air fryers is vital to ensuring you use them properly and in moderation. Aside from health concerns, there are also some general dangers of air fryers that need to be considered. These mainly concern electrical and fire hazards which can be disastrous and even fatal in extreme cases. 

Overheating and Fire Hazards

One of the primary safety concerns with air fryers is the risk of overheating and causing a fire hazard. This is particularly dangerous in a kitchen environment where there are other flammable materials. Overheating can occur if the air fryer is used for extended periods without proper ventilation, or if it's placed on a surface that doesn't allow for adequate air circulation.

Electrical Malfunctions

Air fryers, like any electrical appliance, can experience malfunctions. Faulty wiring, damaged power cords, or internal component failures can lead to electrical shocks or fires. Poorly manufactured or low-quality air fryers are especially prone to these issues. Users should be cautious of budget models that may not adhere to strict safety standards.

How to Avoid Air Fryer Overheating and Electrical Malfunctions

Below we have provided a useful list of steps you can take to reduce the chances of your airfryer overheating or an electrical hazard occurring. These tips should be used generally when operating an airfryer and will ensure the longevity and effectiveness of the appliance. 

Follow manufacturer guidelines: Your airfryer will come with a detailed operating manual so be sure to familiarise yourself with the information before using your air fryer. 

Ensure proper ventilation: As with many kitchen appliances, ventilation is key. Place the air fryer in a well-ventilated area to prevent overheating and allow for proper air circulation.

Do not overfill: Avoid overloading the air fryer basket to ensure even cooking and prevent strain on the appliance.

Regular inspections: Routinely check the air fryer for any signs of damage or wear, such as frayed cords or loose parts.

Unplug when not in use: Disconnect the air fryer from the power source when it's not in operation to reduce the risk of electrical issues and malfunctions.

Air Fryers and Toxic Fumes

It is also worth noting that there is an element of toxicity with air fryers which can pose a significant risk to those working in a kitchen. Air fryers typically have non-stick coatings which can produce toxic fumes if overheated. Likewise, food residue left in the air fryer can accumulate in the air fryer which can cause odours and smoking. 

In this section, we highlight how air fryers can be toxic and how you can avoid the associated dangers.

Non-Stick Coatings in Air Fryers

Many air fryers use non-stick coatings made from polytetrafluoroethylene (PTFE), commonly known as Teflon. When overheated (above 260°C), PTFE can break down and release fumes that are potentially harmful to humans and pets. Perfluorooctanoic acid (PFOA), previously used in some non-stick coatings, has been largely phased out due to similar health concerns.

You can measure this risk by not exceeding the recommended temperature settings. You should also regularly check the non-stick coating of your air fryer to ensure that it is free from damage or scratches which can increase the risk of toxic vapours. If the internal parts of your air fryer begin to rust, be sure to replace them promptly as this deterioration could pose a significant health risk. 

Food Residue and Odours in Air Fryers

Food particles and grease can accumulate in the air fryer over time. If not cleaned properly, this residue can burn and produce unpleasant odours or smoke when the air fryer is in use. Inhaling smoke and fumes from burnt food residue can be irritating to the respiratory system and may contain harmful compounds. 

The best way to handle food residue is to regularly deep clean your airfryer, this includes the air fryer basket, tray, and interior surfaces. You can also soak any removable parts of the airfryer in warm water and use a non abrasive sponge to clear any stubborn residue. 

Nutritional Drawbacks of Air Fryers 

While air fryers are marketed as a healthier alternative to traditional frying, there are several nutritional drawbacks to consider. The perception of air fryers as healthy can result in poor dieting and a reliance on over processed foods. Likewise, evidence shows that cooking methods involving high heat can cause the loss of nutrients and antioxidants in food. 

Understanding these issues can help consumers make more informed decisions about their cooking methods and dietary choices. We expand on these points below. 

Misleading Health Claims

Air fryers are often advertised as a way to significantly reduce fat intake compared to deep frying. While it's true that air fryers use less oil, this doesn't automatically make all air-fried foods healthy. For instance, people might eat larger portions of air-fried foods, thinking they are making a healthy choice, which can negate the benefits of reduced oil usage.

Likewise, air fryers are often used for cooking convenience foods, which are typically high in calories and low in essential nutrients. Relying heavily on these foods can contribute to a less balanced diet while giving the impression that one is eating healthier. 

Loss of Nutrients

Some vitamins and nutrients are sensitive to heat and can degrade during the cooking process. For instance, vitamin C and certain B vitamins are water-soluble and can be lost when foods are exposed to high temperatures for prolonged periods. While air frying may preserve some nutrients better than deep frying, it still involves cooking at high temperatures.

 Cooking methods involving high heat, such as air frying, can reduce the levels of antioxidants in foods. Antioxidants, found in vegetables and some fruits, are crucial for preventing oxidative stress and maintaining overall health. While air frying vegetables might be healthier than frying them in oil, it can still result in a loss of beneficial compounds that our bodies need to function. 

FAQ’s

Can you put plastic in an air fryer?

Plastic should never go in the air fryer as they are not designed to withstand the high temperatures within the device. When plastic is exposed to such high heat, it can melt, warp, or release harmful chemicals into the air and food. This not only poses a risk of contaminating your food with toxic substances but also can damage the air fryer and create a fire hazard.

Why are air fryers bad for you?

We have explained a variety of air fryer risks throughout this article which highlight the reasons that they are bad for you. Risks such as acrylamide formation, electrical malfunctions and toxic coatings can all result from using an air fryer and be a source of potential harm. Similarly, while they are supposedly healthier, air fryers are often used to cook processed foods which can give the illusion of eating better.

Can air fryers cause cancer? 

There is no definitive evidence that links cancer and air fryers specifically as the main concern is the build up of acrylamide. Studies have shown that acrylamide can be carcinogenic in animals, leading to concerns about its potential effects on human health. To minimise the formation of acrylamide, it is advisable to cook foods at the lowest temperature and shortest time necessary to achieve the desired texture and to avoid over-browning or burning foods.

Summary
