Air fryers do cause cancer, because any carbohydrate cooked at a high temperature above 120 degrees will form acrylamide, regardless of whether there is oil or not.

However, it is not only the air fryer that causes cancer, but also the ordinary pot that causes cancer when cooking fried food. Whether it is fried in a large amount or baked in the oven with a little oil on tin foil, it will cause cancer, because the main cause of cancer is not the amount of oil used, but the high temperature. Therefore, if you want to live a healthy life, the most important thing is to eat less fried food.
