Air fryers are now a common feature in a lot of household kitchens and are marketed as a way to get crispy fries and golden chicken with only a fraction of the fat. However, as with any popular food trend, the question that people ask is: Are air fryers better for our health, or are we just exchanging one risk for another? The truth is, science tells us what it really is and also how to use this handy device properly.
What Air Fryers Do
Even though they’re called air fryers, they don’t actually “fry” food. They’re really small convection ovens that blow hot air around food to give it a crispy outside—no vat of fried oil necessary. Air frying is generally a healthier option, says registered dietitian Julia Zumpano, because it reduces added oils by a lot. Even healthy oils such as olive or avocado oil are calorie-rich, so minimizing how much you’re using can decrease your overall fat and calorie consumption.
Tackling the Acrylamide Issue
The other issue people like to complain about with high-heat cooking methods like air frying is acrylamide—a chemical created when starchy foods such as potatoes cook at high heat. Acrylamide is a “probable” human carcinogen. The surprise? It’s not exclusive to air frying. Roasting, baking, and deep frying all produce acrylamide. The good news is that air fryers have been shown to make much less acrylamide than deep frying, so they’re a safer option where golden fries are involved.
Other Possible Hazards—and How Air Fryers Stack Up
If meat is cooked at ridiculously high temperatures, it can lead to the creation of other potentially harmful agents such as polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines (HCAs). Usually, these substances are mentioned in relation to grilling or frying in the pan, but in fact, any method that uses high heat can become the source of the problem. Anyway, in the case of air fryers, the amount of these substances is mostly lower than in regular frying, which is partially attributed to the fact that less oil is used, and the fume trap is more efficient. Besides that, acidifying the protein with a marinade or sprinkling it with herbs such as rosemary may also be of help in reducing the generation of these substances.
The Nutritional Trade-Off
What about the numbers? They say that 100 grams of traditional deep-fried French fries have about 274 kcal and 2.7g of saturated fat. A report published in the Journal of Food Science states that the saturated fat content in the air-fried versions is lowered by as much as 75%. This is not a minor thing for the heart and the total number of calories you consume. Furthermore, the air frying method is free from the dangers that occur during the reheat or reuse of oil, which is one of the sources of the creation of toxic compounds like acrolein.
Moreover, It Is Still Up to What You Decide to Cook
True, the air fryer can be used to lessen the amount of fat and calories in the dish, but it is not a magic tool. The air fryer will not turn heavily processed foods into healthy foods. No matter how you cook them, bacon, frozen chicken nuggets, and prepackaged appetizers will always have additives, salt, and saturated fats. The good part is when you use air fryers for cooking lean proteins, fresh vegetables, and whole foods only.
Tips for Healthier Air Frying
Want to get the most from your air fryer? Follow these easy tips:
- Soak starchy vegetables such as potatoes in water before cooking to limit acrylamide formation.
- Reach for a light golden brown, not deep browning.
- Don’t overload the basket—air circulation matters.
- Keep your air fryer clean to prevent residual grease and charred buildup.
- Use heart-healthy oils (such as olive or avocado) minimally—just a light spritz will suffice.
Keep It Balanced
As useful as air fryers are, they’re not the solution to every meal—and they shouldn’t be. Counterbalance your cooking regimen with other forms of cooking, such as steaming, roasting, sautéing, or eating raw food, to capture a range of textures and nutrients. Keep in mind that no one appliance is going to provide good health. What is a diet rich in fruits, vegetables, whole grains, and lean proteins?
When used thoughtfully, yes—they’re a healthier alternative to deep frying and can support a more balanced approach to eating.
