What You'll Learn
Air fryers can reduce fat and calories
Air fryers are a popular kitchen appliance used to make fried foods such as meat, pastries, and potato chips. They work by circulating hot air around the food to produce a crunchy, crispy exterior. This is a similar method to convection ovens, which also circulate hot air.
Air fryers are marketed as a healthier alternative to deep frying, promising the taste, texture, and golden-brown color of oil-fried foods without the fat and calories. This is because air fryers require less oil to achieve the same texture. Deep-fried foods are cooked by completely submerging them in oil, whereas air-fried foods require just a tablespoon of oil to achieve a similar taste and texture.
Research supports the claim that air fryers reduce fat and calories in fried foods. One study showed that air-fried foods have a lower fat content than deep-fried foods, which means they may be better for health. Another study found that air-fried foods contain fewer calories, with one source claiming a reduction of 70-80%.
Air fryers may also reduce the risk of cardiovascular disease. Deep-fried foods tend to be high in fat and calories, and a higher intake of fried foods increases the risk of obesity. Using less oil to prepare food may help with weight management and the prevention of obesity-related health conditions. Lowering saturated fat intake can also help manage cholesterol levels and decrease the risk of cardiovascular disease.
However, it is important to note that air fryers are not a "free pass" to eat unlimited amounts of higher-calorie foods. The main benefit of air frying over deep frying is the reduction of oil, so adding significant amounts of oil to air-fried foods may reduce the health benefits. Additionally, some studies have found that air frying fish may reduce the amount of "good" omega-3 fatty acids and increase the amount of "cholesterol oxidation products" (COPs), which have been linked to coronary heart disease, hardening of the arteries, and cancer. However, adding fresh herbs like parsley and chives can reduce the amount of COPs in air-fried fish.

Air fryers may increase the risk of certain diseases
Air fryers are a popular alternative to deep frying, as they promise the taste and texture of fried foods with less fat and fewer calories. However, some concerns have been raised about the potential health risks associated with using this cooking method. One of the main worries is the possible formation of harmful compounds during the air frying process, which may increase the risk of certain diseases.
One study found that air-fried fish had higher levels of "cholesterol oxidation products" (COPs). COPs are formed when the cholesterol in meat or fish breaks down during cooking, and they have been linked to an increased risk of heart disease, cancer, and other diseases. Additionally, air frying fish may reduce its omega-3 fatty acid content, which is beneficial for heart health.
Another concern is the presence of acrylamide, a compound that forms in certain foods during high-heat cooking methods, including air frying. While more research is needed, studies in animals have shown that acrylamide can cause cancer at very high doses. A 2024 study found that air-fried potatoes contained slightly more acrylamide than deep-fried or oven-fried potatoes, although pre-soaking the potatoes reduced acrylamide levels across all cooking methods.
Air frying may also increase the levels of advanced glycation end products (AGEs) in food. While it is unclear if air frying produces more or less AGEs than deep frying, consuming too many AGEs over time may increase the risk of developing chronic diseases.
The type of food cooked in the air fryer also matters. Nutrient-dense foods like fruits, vegetables, whole grains, fatty fish, and lean meats are generally just as nutritious in the air fryer as in the oven. However, air frying starchy foods like potatoes may increase the levels of slowly digestible starch, which could have a slightly lower impact on blood sugar.

Air fryers are safer than deep frying
Air fryers have become increasingly popular, with many people choosing them over deep fat fryers. This is largely due to the health benefits that air fryers offer over deep frying.
Deep-frying involves heating large amounts of oil to very high temperatures, which can pose a safety risk. There is a risk of spilling, splashing, or accidentally touching hot oil, which can cause burns. Air fryers, on the other hand, do not use oil as a cooking medium, and so there is no risk of coming into contact with hot oil.
Deep-fried foods also tend to be much higher in fat and calories, which can increase the risk of obesity and other health issues such as cardiovascular disease. Air fryers require a fraction of the oil that deep fryers need, resulting in healthier meals with similar flavors and textures. Lowering saturated fat intake can help manage cholesterol levels and decrease the risk of cardiovascular disease.
A 2020 study found that air frying chicken produced less acrylamide and polycyclic aromatic hydrocarbons (PAHs) than deep frying. Acrylamide is a compound that forms in certain foods during high-heat cooking methods, and research has found that it causes cancer in animals given very high doses. While these doses are much higher than those found in human food, more research is needed to determine its effects on humans.
In addition to the health benefits, air fryers are also easier to store, clean, and use than deep fat fryers. They are a safer option than deep frying, offering a convenient and healthier way to enjoy fried foods.

Air fryers may not be healthier than other cooking methods
Air fryers have become increasingly popular due to their promise of healthier fried food. They work by circulating hot air around food to create a crispy texture, and they require less oil than traditional frying methods. However, it is important to consider whether air fryers are truly healthier than other cooking methods.
One concern about air fryers is the potential for harmful compounds to develop during the cooking process. Acrylamide, for example, is a chemical that forms in certain plant-based foods, such as potatoes, during high-heat cooking methods like frying, roasting, and baking. While it is present in lower amounts in air-fried foods compared to deep-fried or oven-fried potatoes, it is still present, and research has linked it to cancer in animals. Similarly, a study found that air-frying fish increased the levels of cholesterol oxidation products (COPs), which are linked to an increased risk of heart disease, cancer, and other medical conditions.
Another consideration is the impact of air frying on the nutritional content of food. While air fryers can reduce the amount of fat and calories in fried foods, they may not necessarily improve the overall nutritional value. In fact, one study found that frying fish retained the least amount of heart-healthy omega-3 fatty acids compared to other cooking methods like steaming, baking, or grilling. This suggests that while air frying may be a healthier alternative to deep frying in terms of fat and calorie content, it may not necessarily be the healthiest option for retaining certain nutrients.
Additionally, it is important to remember that the health benefits of air frying are largely dependent on the types of food being cooked. Air frying may be a healthier alternative for cooking starchy foods like potatoes, as it breaks down the starch more slowly, potentially leading to a lower impact on blood sugar. However, this does not mean that air-fried foods are a healthy option across the board. As one source points out, nutrient-dense foods like fruits, vegetables, whole grains, fatty fish, and lean meats are generally just as nutritious in an air fryer as they are in an oven. In other words, the air fryer does not inherently add nutritional benefits to food.
Furthermore, some people have expressed skepticism about the idea that air fryers are a "free pass" to eat unlimited amounts of higher-calorie foods. While air fryers may reduce the amount of oil and fat in fried foods, it is important to consider the overall diet and not rely solely on the cooking method to determine the healthiness of a dish. As such, it is clear that while air fryers may offer some health benefits compared to deep frying, they may not necessarily be healthier than other cooking methods like steaming, baking, or grilling, which can better retain certain nutrients.

Air fryers may not improve the nutritional value of food
Air fryers are promoted as a healthier alternative to deep frying, as they require less oil to achieve a similar texture. However, it is important to note that air fryers may not significantly improve the nutritional value of food.
Air fryers work by circulating hot air around food, creating a crispy texture without submerging the food in oil. This results in a lower fat content compared to deep-fried foods, which is generally considered beneficial for health. However, the nutritional value of the food being cooked remains largely unchanged.
When comparing air fryers to ovens, the appliances have similar functionality, and the nutritional profile of the cooked food is generally the same. The main difference is that air fryers cook food faster. Therefore, the nutritional benefits of using an air fryer over an oven are minimal.
Additionally, the type of food being cooked is a more critical factor in determining its nutritional value than the cooking method. Nutrient-dense foods like fruits, vegetables, whole grains, fatty fish, and lean meats are generally nutritious regardless of whether they are cooked in an air fryer or an oven.
While air fryers can be a healthier alternative to deep frying, they do not inherently improve the nutritional value of the food being cooked. It is important to consider the type of food being cooked and the overall diet rather than relying solely on the cooking method to determine nutritional value.
