Cooking with Air Fryers: Healthy or Unhealthy?

Air Fryer: The Trending Kitchen Appliance

Air fryers are portrayed to be health-conscious and innovative equipment for frying foods. However, it is forgotten that they hold both upsides and downsides to health. The common reason cited for the usage of air fryers is being able to eat fried foods without worrying about calories and fat intake. This article will help you understand whether air fryers are safer and healthier alternative to satisfy your cravings for deep-fried foods(1^✔ ✔Trusted Source

How do Air Fryers Work?

In air fryers, heat is transferred using hot air. The hot air keeps circulating inside the chamber removing moisture from food in order to improve the texture of food. Since air carries less heat the speed of the moving air is very high. The fan positioned above the food tray increases air circulation, escalates convection, and improves the transfer of heat into food(2^✔ ✔Trusted Source

Are Air-fried Foods Healthy?

Fried foods are popular snacks across several cuisines and have been consumed for many years. The health impacts of fried foods have been researched by many. As fried foods are an important part of the menu, it is ideal to choose healthy ways of cooking them. Air-fried foods may tend to have a lower fat content and an appealing appearance and taste. In a study that examined the quality attributes of air-fried falafels. Air frying turned down about 45 percent of the fat content in falafel than deep-fried falafels. Appearance and hardness scores were higher for air-fried falafels. Calories also tend to be lesser in air-fried foods than in traditional deep-fried foods(3^✔ ✔Trusted Source

Traditional Deep Frying vs. Air Frying

In the traditional frying method or deep frying, oil is used to immerse the food. In deep frying, a combination of convection (from hot oil to food) and conduction (inside the food) happens. When oils are exposed to high temperatures toxic compounds may be produced. In deep frying, the Maillard reaction (between amino acids and sugars) results in the browning of the food and may also result in acrylamide production. Acrylamide is a compound found to be linked with the onset of cancers including esophageal, pancreatic, breast, endometrial, and ovarian.

Whereas, the air frying method turns away such bad impacts on health. There is minimal oil being used and heat is transferred at a high rate and is evenly distributed. The use of minimum oil and less energy consumption depicts it to be good for health. Studies have also shown better sensory attributes for air-fried foods than deep-fried foods(9^✔ ✔Trusted Source

Air Fryers: Pros and Cons

Air fryers are marketed to be a healthy choice. However, they hold both pros and cons.

Air frying health benefits include the following:

• Air fryers are time efficient. It reduces about 50 percent of the cooking time and 75 percent of the preheating time required(1^✔ ✔Trusted Source

The downsides of air fryers include -

• Moisture removal is comparatively less in air-fried foods which may result in less crispy foods. Deep-fried foods have more moisture removed contributing to crispiness(4^✔ ✔Trusted Source

• A study evaluated the formation of cholesterol oxidation products(COPs) and degradation of polyunsaturated fatty acids in air-fried sardine fish. COPs may be interlinked with health problems like atherosclerosis, coronary heart disease, and chronic diseases. The results of the study revealed that air fryers tend to increase the formation of cholesterol oxidation products (COPs). Oxidation of lipids was found to be reduced with the use of fresh herbs such as parsley and chives(7^✔ ✔Trusted Source

Conclusion

Frying is a commonly used cooking method that is based on dehydrating food. Although air fryers have swept the cooking world off its feet, the health world is still skeptical about it. Studies on its effect on the nutritional and health aspects show both good and bad attributes. Air fryers aid in the easy cooking of different foods. However, some studies have shown a negative impact on health due to the production of toxic compounds like COPs. A healthy eating pattern not only includes less intake of calories and fat. Consuming balanced meals, regular exercise, adequate sleep, and avoiding social habits like smoking and alcohol consumption sculpts a healthy lifestyle.
