However, it’s important to note that other harmful compounds may still be formed during the process of air-frying.Īldehydes, heterocyclic amines, and polycyclic aromatic hydrocarbons are all other potentially dangerous chemicals that are formed with high heat cooking and may be associated with a higher risk of cancer ( 13).įurther research is needed to determine how air-frying may affect the formation of these compounds.Want tech that can help you do more healthy eating? With an air fryer, you can still make favourites like chips. In fact, one older study found that air-frying reduced acrylamide by up to 90%, compared with traditional deep-frying ( 12). The Environmental Protection Agency also finds that acrylamide is “likely to be carcinogenic to humans” ( 11).Īir-frying your food instead of using a deep fryer may help lower their acrylamide content. However, results are mixed and other reviews of studies suggest that fats in vegetable oil may be associated with a lower risk of heart disease ( 7).Īir fryers can decrease the formation of harmful compoundsīesides being higher in fat and calories, frying food can create potentially dangerous compounds like acrylamide.Īcrylamide is a compound formed in carbohydrate-rich foods during high heat cooking methods like frying ( 9).Īccording to the International Agency for Research on Cancer, acrylamide is classified as a “probable human carcinogen,” meaning that some research shows that acrylamide may be linked to cancer development ( 10).
Some studies suggest that a higher intake of fat from vegetable oils is associated with an increased risk of conditions like heart disease and inflammation ( 6). This can have a major impact on your health. Studies comparing the characteristics of deep-fried and air-fried french fries found that air-frying resulted in a final product with substantially less fat and less crispy texture but a similar color and moisture content ( 4, 5). Even though the food does not absorb all of that oil, using an air fryer can significantly cut down on the overall fat content. This means that deep fryers use up to 50 times more oil than air fryers. While many recipes for deep-fried dishes call for up to 3 cups (750 mL) of oil, air-fried foods need only about 1 tablespoon (15 mL). This is because air fryers require significantly less fat for cooking than traditional deep fryers.
Some brands claim that using an air fryer instead of a deep fryer can help cut the foods’ fat content by up to 75%. For example, a chicken breast that has been fried contains more fat than an equal amount of roasted chicken ( 2, 3). Using an air fryer can help cut fat contentĭeep-fried foods are generally higher in fat than foods prepared using other cooking methods.
