Why Air Fryers Aren’t as “Healthy” as You Think
Air fryers are touted as a guilt free way to enjoy fried foods, but the truth is more complicated. While they use less oil than deep frying, the high heat cooking process can still pose risks to your health. Let’s find out what are the surprising disadvantages that don’t make it into the glossy ads.
Oxidative Stress: When Your Salmon Turns Sneaky
Ever air fried a juicy salmon fillet and thought you were boosting your omega 3s? Think again. A 2024 study published in Food Chemistry found that air frying fatty fish like salmon or sardines increases cholesterol oxidation products (COPs). These compounds are linked to heart disease and inflammation when fats are exposed to high heat. Unlike deep frying, which uses more oil to stabilize the fat, air Frying’s minimal oil and intense heat can speed up this process.
Take health conscious mom Neha, who shared with me: “I use air fry salmon every week, thinking it was so healthy. Then I read about COPs and started wondering if I was doing more harm than good!” Sarah isn’t alone many of us assume air frying preserves nutrients, but when it comes to fatty foods, it can actually deplete the heart healthy fats.
Quick tip: To reduce COP formation, add antioxidant rich herbs like parsley or rosemary before air frying. Better yet, try steaming fish a few times a week to keep the omega 3s intact.

What is oxidative stress from air fryers? Oxidative stress from air fryers occurs when high heat creates cholesterol oxidation products (COPs) in fatty foods like salmon, which can increase the risk of heart disease. Use herbs or lower temperatures to reduce this.
Advanced Glycation End Products (AGEs): The Silent Inflammation Trigger
You may have heard of acrylamide, a chemical in air fried potatoes linked to cancer risk. But what about advanced glycation end products (AGEs)? These compounds, formed when food is cooked at high temperatures, can cause inflammation and contribute to diabetes and aging. A 2024 study in Nutrition Research found that air frying produces fewer AGEs than deep frying but more than steaming or boiling — a nuance most blogs skip.
For example, air frying chicken wings or processed foods can increase AGEs, especially if you cook at the highest temperature. My friend Mike, who loves air frying nuggets, noticed that he felt sluggish after his daily air fryer meal. Could AGEs be to blame? While the research is not conclusive, frequent air fryer use may increase AGEs over time.
Quick tip: Balance air frying with gentle cooking methods like poaching or steaming to reduce the amount of AGEs. And be careful with processed foods – they’re AGE magnets!

What are AGEs in air fryer cooking? Advanced glycation end products (AGEs) are inflammatory compounds that form during highheat cooking, such as air frying. They are linked to diabetes and aging, but can be reduced by using lower temperatures or steaming.
Safety Risks You Didn’t See Coming
Beyond health concerns, air fryers can pose safety risks that rarely make the headlines. From chemical exposure to fire hazards, here’s what you need to know to keep your kitchen (and family) safe. PFAS in Nonstick Coatings: A Chemical Concern
Many air fryers use nonstick coatings, which may contain PFAS (“forever chemicals”). These compounds, which have been linked to hormone disruption and cancer, can leach into food if the coating is scratched or overheated. In 2023, concerns were raised when popular air fryer brands like Cosori and Insignia were recalled after reports of PFAS contamination and overheating risks.
Take Supriya, a home cook who also shared with me: “My air fryer’s coating started peeling after a year, and now I’m worried about what I’m eating!” Her story is not unique – using a low quality air fryer or improper use (such as using metal utensils) can increase PFAS exposure.
Quick tip: Choose an air fryer with a ceramic or stainless steel basket and check for BPA- and PFOA-free certification. Never use metal containers, and replace your air fryer if the coating looks corroded.

Is the nonstick coating on an air fryer safe? Some air fryer nonstick coatings contain PFAS, which can leach into food if damaged or overheated, posing risks like hormone disruption. Choose a ceramic coated or PFAS free model.
Fire Hazards: When Your Air Fryer Overheats
Did you know that air fryers can catch fire? The U.S. Consumer Product Safety Commission has reported 205 incidents of Cosori air fryers overheating or catching fire, 10 of which resulted in minor injuries. Faulty wiring or overcrowding in the basket can put your air fryer at risk of fire. A 2024 post from a California user went viral after their air fryer exploded while cooking late at night: “I thought the air fryer was safe, but my kitchen almost burned down!”
Quick tip: Always unplug your air fryer when not in use, avoid overcrowding the basket, and store it in a well ventilated area to prevent overheating.

Can an air fryer cause a fire? Yes, air fryers can cause a fire due to faulty wiring or overcrowding. To be safe, unplug the device when not in use and ensure proper ventilation.
The Environmental Cost of Your Air Fryer Addiction
Air fryers aren’t just about your health—they also have an impact on the planet. This aspect is rarely discussed, making it a new topic for your readers.
Energy Use and Waste: Not So Eco-Friendly
Air fryers are energy hogs compared to ovens for larger meals, using up to 1,500 watts of electricity per hour. Plus, their non stick materials aren’t always recyclable, which adds to the amount of waste in landfills. A 2024 report by Green Living magazine highlighted how PFAS laden air fryer baskets pose challenges for disposal, yet most blogs only focus on the cooking benefits.
I felt a pang of guilt when I discovered that my air fryer wasn’t as green as I thought it would be. If you’re environmentally conscious, this hidden cost may make you reconsider using it frequently.
Quick tip: Use your air fryer in smaller batches to save energy and choose sustainable, PFAS free models to reduce waste. Check local recycling programs for proper disposal.

Myth vs. Reality: Debunking Air Fryer Fears
With so much hype surrounding air fryers, it’s easy to fall into the trap of myth. Let’s separate fact from fiction with evidence based clarity.
Myth: Air Fryers Eliminate All Health Risks of Frying
Reality: While air fryers use less oil, they don’t eliminate risks like acrylamide or AGEs. A 2024 study found that air fried potatoes can sometimes contain higher levels of acrylamide (12.19 μg/kg) than deep fried ones (8.94 μg/kg), challenging the “healthy” label.
Myth: Air Fryers Preserve All Nutrients
Reality: Air frying can destroy heat sensitive nutrients like vitamin C and polyphenols, especially in vegetables like broccoli. Steaming or boiling often preserves more nutrients, according to a 2023 study in the Journal of Food Science.
Quick tip: Soak potatoes in water for 30 minutes before air frying to reduce acrylamide, and mix up your cooking methods to maximize nutrient retention.
How to Use Your Air Fryer Safely and Healthily
Don’t throw away your air fryer just yet! With a few changes, you can reduce the risks and enjoy its benefits. Here’s how:
- Lower the Heat: Cook at medium temperatures (below 400°F) to reduce COPs, AGEs, and acrylamide.
- Choose Safe Models: Choose a PFAS free, ceramic coated air fryer from a reputable brand.
- Ventilate Your Kitchen: Use a range hood or open windows to reduce exposure to oil aerosols.
- Balance Your Cooking: To preserve nutrients and reduce AGEs, combine air frying with steaming, boiling, or grilling.
- Clean Regularly: Prevent residue buildup, which can emit harmful fumes over time.
Should You Ditch Your Air Fryer?
So, is it time to say goodbye to your air fryer? Of course not. Air fryers may be a handy tool for quick, low fat meals, but they’re no health miracle. By understanding the risks like oxidative stress, PFAS exposure, and environmental impacts, you can make smarter choices. My air fryer still gets a workout, but I’m more aware now — and I hope you will too.
