When you compare air fried food to deep fried food it is much healthier because there is hardly any oil used at all. The only oil I use is from my Pam cooking spray. I spray only the food once or twice because most air fryer baskets are nonstick. If you are considered about using aerosol sprays for the environment or your health buy a Misto Brushed Aluminum Oil Sprayer can from Amazon and fill that with your favorite oil.
