However; they are always two sides to a coin. Although; fryers bring plenty of health benefits; however, they have one big potential danger that outweighs the benefits. That is Ninja Air Fryer Cancer Warning!

Considering the great concern over it; we will highlight “does ninja air fryer cause cancer?” and if it does; what can be done to avoid it. Let’s explore this air fryer cancer scandal in great detail!

Ninja Air Fryer Cancer Warning?

Ninja Air Fryers are safe; however, their cooking at high temperatures has caused scientists to believe that they can produce potentially harmful chemicals making humans vulnerable to cancer particularly liver breast, kidney, and colon cancer. Considering this; the product has been given the Prop 65 Warning.
Do note that almost all modern-day conveniences have similar drawbacks; for example cell phones were known to emit radiation making humans vulnerable to brain tumours.

Why Does Ninja Air Fryer Have Prop 65 Warning? 

The air fryer P65 Warning indicates that the air fryer has the potential to cause cancer, and other congenital disabilities. It is particularly found to cause breast, kidney, ovary and pancreatic cancer. Air fryers use hot air and high temperatures to cook food. Studies suggest that when plant-based foods like fries, cereals, chips, cookies etc are cooked at high temperatures a chemical compound called Acrylamide is produced. This is a carcinogen meaning it can cause cancer. Considering this potential risk; it has prop 65 warning.

Air Fryer Health Risk – Beyond The Hype!

Acrylamide Discovery – Let’s Get Technical:

Similar to other modern-day inventions; it’s stated that air fryers produce cancer. Why? Acrylamide is a carcinogenic chemical that is produced when amino acid sugars react with asparagine. This chemical reaction takes palace when scratch-rich food like chips, cookies, and fries are cooked at high temperatures.

This carcinogenic chemical is labelled as a GROUP 2A carcinogen for humans. Since air fryers are designed to cook foods at high temperatures; it is suggested that they can produce acrylamide when cooking plant-based foods.No association between acrylamide and cancer has been found yet except for: 

  • Kidney Cancer
  • Uterine Cancer
  • Ovary Cance

This raised concerns that maybe air fryer produces a high level of acrylamide chemicals- however recent 2020 study indicated that air fryers can be used to reduce cancer risk. They can reduce acrylamide formation.

Note: There is no conclusive evidence for air fryer is cancerous to humans. No evidence suggests that acrylamide increases cancer risk in humans. The experiment was conducted on animals; and till today; we have only evidence that acrylamides cause cancer in animals. It hypothesised that if it causes cancer risk in animals then maybe humans are prone too; however, research is still continuing in this field. 

Can Air Fryers Cause Cancer?

Can Air Fryers Cause Cancer? 3 Ways To Reduce This Risk

Ways For Controlling Acrylamide Production:

It’s suggested that you avoid putting plant-based foods in the refrigerator

  • Air fryers come with adjustable temperature controls; therefore this feature is very beneficial as you can cook plant-based meals at low temperatures. Cook them till they are light golden from the outside. Dont overcook.
  • Its recommended to post dry or do blanching of vegetables before cooking
  • High-starch food produces more acrylamide; therefore the best way to control its production is to use low-starch content foods like chicken, vegetables etc

Info: A study conducted on preheating found that preheating French fries with salt, citric acid, calcium lactate, glycine, and vitamin B2 can drop acrylamide production by 90%.

Aromatic Hydrocarbon & heterocyclic Amines – The Air Fryer Danger!

The air fryers have other negative side effects which include the production of Aromatic Hydrocarbon & heterocyclic Amines. These toxic chemicals are produced when certain food types rich in proteins or fats like meat are cooked at high temperatures. It found that certain cooking methods like grilling or charring the meat can increase the production of these chemicals. These chemicals are produced by the following reactions:

Pyrolysis: This occurs, when high heat breaks down the fat, protein and carbohydrate, contentsof the food and produce the aromatic hydrocarbons

Maillard reaction: This occurs when carbohydrates and proteins in food are broken down by high heat

Drippings: When food (meat) is cooked; the fats and juices from the meat can drip off onto the surface and get burnt. This results in the production of smoke and aromatic hydrocarbons.

Tips For Reducing Aromatic Hydrocarbon & heterocyclic Amines Production:

  • It’s best that you use leaner meat cuts rather than fatty meats as they can produce more dripping-ultimately resulting in more aromatic hydrocarbons
  • As suggested in acrylamides; cook meat at lower temperatures to reduce aromatics
  • It’s best that you use plenty of other effective cooking methods like boiling, steaming, and poaching. It found that these cooking techniques can effectively lower HCAs production.
  • Avoid overcooking food
  • It’s best that you marinate the meat before cooking them in the air fryer. It’s effective that you marinate with vinegar or lemon juice as they have been found to reduce HCAs.

Reheating Oil – Health Deadly:

Air fryers aren’t designed to recycle oils; nor do they use vast amounts of oils to develop crunchy and pillowy food. Their reduced oil fry technique helps reduce the risk of cardiovascular disease. However; if you don’t clean the machine after each cooking cycle; then the oil droplets from the previous cooking, get reheated and cause the production of smoke and other aromatic hydrocarbons. This can cause liver problems, colon cancer, breast cancer, prostate cancer and lung cancer.

How To Get Out? 

  • It’s simple; deep clean your air fryer to avoid oil reheating.

Food Poisoning – Lethal: 

Food poisoning is caused by ingesting toxic or contaminated foods. The toxins are particularly developed when you don’t properly clean your machine. Non-proper cleaning can result in the fast growth of bacteria; however high temperatures inside the fryer destroy them. The major cause of food poisoning by air fryers are undercooking of meals, especially frozen food. They have salmonella bacteria which then causes food posing. 

How To Get Out?

  • Properly cook frozen food 
  • clean your fryer regularly

Cholesterol Oxidation – Slow Poison:

Air fryers can cause cholesterol oxidation of cholesterol-rich foods which can result in the development of atherosclerosis. 

How to Get Rid Of It?

  •  It’s important to cook and store cholesterol-rich food properly. Store the meal in air-tight containers
  • Avoid high-temperature cooking
  • Consume nutrients-rich veggies

How Do Air Fryers Cause Cancer? 

Air fryers themselves don’t cause cancer. They use the convection cooking method where they circulate the hot air and cook food evenly. However, it has been found that food high in protein or fat content when cooked at high temperatures; results in the production of heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) which cause cancer.

These food include meat, fish, poultry etc. Whether you grill, boil, saute or fry them; they will produce HCA, PAHs chemicals. Therefore; to reduce the risk; it is usually suggested that you avoid overcooking the meat; moreover marinate it before cooking and keep on flipping it during the cooking process.

Additionally; it’s suspected that cooking plant-based food like fries, mashed potatoes, potato chips etc can produce acrylamides-a carcinogen that increases the risk of cancer. For this; it’s suggested to cook plant-based meals until they are lightly golden. It’s recommended to avoid overcooking them.

Are Ninja Air Fryers Healthy And Safe To Use?
