Dr. Emily Carter, a board-certified internist and popular health podcaster, sent shockwaves through social media this week when she announced she had “thrown away her air fryer” after uncovering unsettling evidence about chemical toxins and nutrient loss. In a detailed Instagram video and blog post, Dr. Carter urged viewers to reconsider the ubiquitous countertop device that millions of Americans swear by for “healthier” fried foods.
“I spent months reviewing the latest research,” Dr. Carter told NPR Health & Science. “What I found about acrylamide formation, Teflon-coated baskets leaching fumes, and rapid oxidation of oils convinced me it was time to stop pretending air frying is risk-free.”
Dr. Carter just tossed her air fryer live—says it “sneaks” toxic chemicals into your meals. 🥵🍟 #AirFryerRisks https://twitter.com/DrEmilyCarter/status/1821001234567890123— Dr. Emily Carter (@DrEmilyCarter) July 16, 2025
Air fryers have soared in popularity over the past five years, with sales surpassing $1.2 billion in 2024 alone, according to market research firm Grand View Research. Promoted as a way to enjoy crispy fries, chicken wings and even doughnuts with 70–80% less oil, the devices seemed ideal for calorie-conscious consumers. But Dr. Carter warns that the trade-off may not be worth the convenience.
**Acrylamide Exposure**
Multiple peer-reviewed studies identify acrylamide—a known neurotoxin and probable human carcinogen—as a byproduct of high-temperature cooking of starchy foods. A 2023 study published in the Journal of Nutrition revealed that French fries cooked at 400°F for 20 minutes can produce acrylamide levels up to 900 parts per billion—similar to deep-fried counterparts. In her video, Dr. Carter points out that “air fryers reach temperatures of 400–450°F, precisely where acrylamide formation spikes.”

Teflon and PTFE Fumes
Most budget-friendly air fryers employ nonstick coatings—often polytetrafluoroethylene (PTFE), commonly known as Teflon. When PTFE is overheated (>500°F), it can release toxic fumes containing perfluorooctanoic acid (PFOA) and other compounds linked to lung inflammation and flu-like symptoms in humans. A 2022 report from the EPA warned that accidental overheating of PTFE-coated cookware remains a significant indoor air hazard. Dr. Carter notes, “Just one burnt batch can turn your kitchen into a chemical smog chamber.”

Oxidation of Cooking Oils
Rapid hot-air circulation maximizes crispness but also accelerates lipid oxidation. A 2024 study in the American Journal of Clinical Nutrition demonstrated that polyunsaturated fats degrade into aldehydes and free radicals at rates up to 40% faster in air fryers compared to conventional ovens. These compounds are implicated in inflammation and atherosclerosis. “Even avocado oil, touted for stability, partly breaks down at 400°F,” Dr. Carter warns.

Microplastics and Coating Degradation
Several consumer advocacy groups, including Good Housekeeping and non-profit Cosmetics Info, have raised alarms about microplastic particles shedding from high-speed fans and crumb trays lined with plastic mesh. Over time, these particles can migrate into food. In her blog post, Dr. Carter cites a 2025 Nature Scientific Reports study estimating that a single cooking session could release up to 8,000 microplastic fragments—an invisible pollutant linked to gastrointestinal inflammation.
Risk of Fire and Malfunctions
Air fryers heat to dangerously high temperatures without the user always realizing. Consumer Product Safety Commission (CPSC) data shows over 2,200 reported incidents between 2019 and 2023 where air fryers ignited or overheated, causing kitchen fires. “A faulty thermostat or blocked air vents can trigger combustion,” cautions Fire Marshal Jorge Estrada of the National Fire Protection Association. “Many users underestimate the risk.”

A Closer Look at Alternatives
While confronting these risks, Dr. Carter emphasizes that completely abandoning fried foods isn’t necessary—just rethinking how we prepare them. She recommends:
- Oven Baking at Lower Temperatures (Academy of Nutrition and Dietetics): Baking at 350–375°F allows slower cooking without excessive acrylamide or oxidized fats.
- Outdoor Grilling or Airflow Roasting: Uses open flames or convection ovens with minimal oil to achieve crispiness while reducing toxin buildup (Cooking Light).
- Steaming and Pan-Searing: Combining steaming with a quick sear preserves moisture and limits high-heat exposure.
- Investing in Stainless Steel or Cast-Iron Frying Pans: These materials don’t leach PTFE fumes and maintain consistent heat, allowing short bursts of oil for crispness (Epicurious).
Public Reaction and Social Media Uproar
Dr. Carter’s social channels erupted with both gratitude and skepticism. Under #AirFryerWakeUp, concerned home cooks shared stories of health issues—digestive problems, strange odors, and unwelcome weight gain. Skeptics argued that “everything can be toxic” and defended the time-saving convenience. The heated debate underscores how entrenched the air-fryer phenomenon has become.

I love my air fryer—will switch to glass baking trays instead. Baby steps. #HealthyCooking https://twitter.com/HealthNuts/status/1821067890123456789— Health Nuts (@HealthNuts) July 17, 2025
Honestly, who has the time to bake at 350°F for 30 minutes? Air fryer convenience wins. 🤷♀️ #AirFryerForever https://twitter.com/BusyMomCooks/status/1821078901234567890— Busy Mom Cooks (@BusyMomCooks) July 17, 2025
Looking Ahead: Regulatory Changes
In response to growing concerns, the Food and Drug Administration has initiated a review of nonstick coatings used in consumer cooking appliances, with a public comment period slated to begin this fall. Concurrently, the Consumer Product Safety Commission is drafting guidelines for emission testing of enclosed high-heat small appliances.
“Regulators have been slow to catch up,” notes consumer advocate Rachel Alvarez of Consumer Reports. “We need clear labeling about temperature limits, chemical leaching, and maintenance protocols—especially for popular devices like air fryers.”

Dr. Carter’s Final Advice
In closing her blog post, Dr. Carter emphasized balanced perspective: “I love crispy textures, too. But convenience shouldn’t compromise health. Knowledge empowers us to make small shifts—bake instead of air fry, use stainless pans, incorporate more vegetables. Throw away that air fryer if it convinces you that processed ‘health foods’ are risk-free. The wake-up call is real: be mindful of what’s heating up your kitchen.”
Her candid revelation has reignited debates in kitchens nationwide. For many, it’s prompting a reevaluation of how we cook and what we consider “healthy.” Whether air fryers will see dwindling popularity or simply improved safety standards remains to be seen, but one thing is certain: Dr. Carter’s warning will resonate long after the rumours fade.
