An air fryer cooks food with hot circulating air instead of submerging it in oil, and the difference shows up clearly in the numbers, one entry in the broader comparison of how cooking method affects your gut. Using roughly a tablespoon of oil instead of a deep fryer's full submersion can cut the calories that would otherwise come from added fat by up to 80%.[1]
Acrylamide, a compound formed during high-heat cooking that's been linked to cancer in animal studies at high doses, also drops substantially with air frying compared with deep frying, though it doesn't disappear entirely.[1] Human research on acrylamide at the levels found in food is still limited, so the reduction is a genuine upside without being a guarantee of zero risk.
What to do with this
Switching from deep frying to an air fryer is a simple way to cut added fat and reduce acrylamide formation, both real, measurable wins backed by the available research. That benefit depends entirely on what you're cooking. Air-fried vegetables or lean protein are a genuine improvement over deep-fried versions, while air-fried processed food, bacon, frozen snacks, still carries most of its original saturated fat and sodium, much like the tradeoffs described in how Filipino street food habits affect gut health over time. Use an exhaust fan and avoid overcrowding the basket, since smoke and uneven cooking both increase with poor airflow, the same kind of heat-source detail covered in wood fire vs. gas cooking and gut health.
