What is nonstick cookware?
A nonstick cookware surface is engineered such that food does not stick to it and is called nonstick cookware. The non-stick surface allows food to brown without sticking. That’s because the surface of the pan is coated with a glossy or waxy material.
But What is PTFE and Teflon? Are all nonstick pans Teflon
The waxy surface in the case of Teflon non-stick pans is made of polytetrafluoroethylene (PTFE). PTFE is a synthetic fluoropolymer that has a variety of uses, including as a coating for cookware. Teflon is a brand name for PTFE-coated cookware. Not all PTFE or other fluoropolymers used to make nonstick cookware fall under the Teflon brand.
PTFE or Teflon is the most well-known type of nonstick coating, but it’s not the only one. There are also pans coated with ceramic, anodized aluminum, and other materials.

How do nonstick pans work?
The nonstick coating on pans works by creating a barrier between the food and the pan. This barrier prevents food from sticking to the pan and makes cleanup a breeze.
The chemical composition of PTFE is based on two carbon atoms and four fluorine atoms. The molecular structure has an outer shell filled with fluorine atoms. This shield of fluorine atoms keeps the carbon atoms from reacting with other chemicals.
In addition to their resistance to reacting, fluorine atoms also play a role in giving PTFE a low coefficient of friction. This means that PTFE doesn’t stick to other materials when they come into contact with each other, making it easier to slide them around.
The nonstick coating is applied to the pan during the manufacturing process. It’s usually applied by spraying or rolling on a liquid PTFE, which then dries and forms a hard, smooth surface.
So Is Nonstick Cookware Safe?
People around the world utilize nonstick pots and pans regularly for cooking. The nonstick cooking surface is excellent for flipping pancakes, turning fish, and frying eggs. It can be used for preparing specialty foods that might otherwise stick to the pan.
However, some sources have raised controversial concerns surrounding nonstick cooking surfaces, such as Teflon. Critics claim that they are detrimental to health and may have potentially negative repercussions.
Teflon and PFOA exposure – Is nonstick coating toxic?
People have been using cookware with polytetrafluoroethylene (PTFE) since the 1960s. Recently, there has been a lot of discussion about whether this type of cookware is safe. Most of the debate is about a substance called perfluorooctanoic acid, or PFOA. This acid is used in making many types of fluoropolymers, including PTFE.
PFOA is harmful to both pet birds and humans. There were multiple bird deaths due to fumes from PTFE nonstick coatings, as well as two specific cases of polymer fume fever in humans.
The good news is that PFOA has been phased out of production in the United States since 2015. However, it can linger in the environment for years.
So even though PFOA is no longer being used to make PTFE, it’s still present in the environment, used in fast-food packaging and stain-resistant coatings and we’re still being exposed to it.
Exposure to PFOA has been linked to a variety of health problems, including:
- Kidney and testicular cancer
- Liver damage
- Thyroid disease
- High cholesterol
- Hormone disruption
- Immune system problems
- Reproductive issues
- Early onset of puberty
Dangers of Overheating Teflon Cookware – When is nonstick cookware unsafe?
Health experts agree that Teflon itself is harmless when used as intended. The real danger comes when Teflon is heated to high temperatures.
When Teflon is heated to temperatures above 570°F (300°C), it begins to break down and release harmful chemicals into the air. These chemicals have been linked to polymer fume fever, a condition that causes flu-like symptoms, such as:
- Muscle aches
- Shortness of breath
Inhaling these chemicals can also cause lung damage and respiratory problems. In severe cases, it can be fatal.
Fortunately, polymer fume fever is rare. It typically only occurs in people who are exposed to high concentrations of Teflon fumes for a long period of time.
Why are nonstick pans bad for birds?
PFOAs are extremely harmful to birds. The use of Teflon-coated lightbulbs has resulted in the destruction of chicken farms.
Tips to minimize your PFOA exposure when cooking
Today, there is not enough scientific evidence to support the claim that nonstick pans are unsafe for human use if used according to manufacturers’ instructions. However, if you’re concerned about potential health risks, there are some steps you can take to minimize your exposure to PFOA.
1. Never preheat an empty pan
I carried out an experiment and heated two empty nonstick pans. I chose one cheap lightweight nonstick pan and the other one was high-end heavier nonstick pan. The lightweight pan reached over 500 F in under 2 mins while the heavier pan took just under 4 mins to reach 500 F.
2. Don’t exceed the recommended cooking temperature
Cook on medium heat. Nonstick is best suited for fried eggs, fish, and, pancakes. These foods do not require high heat. Common mediocre non-stick pans can reach over 500 F in under 3 mins even with oil in them.

3. Ventilate your kitchen
If you are cooking on high heat, keep your exhaust fan and windows open for ventilation. This will clear out any fumes.
4. Don’t broil or sear meats
Broiling and searing meat require a temperature above than recommended safe temperature for nonstick pans so avoid this cooking technique while using nonstick pans.
5. Choose a heavier base nonstick pan
The lightweight pans are cheap but they heated up twice as fast as the heavier non-stick pan in my experiment. So choose heavier non-stick pans even if they are more pricer.

6. Try ceramic coatings
Although they don’t last as long as the Teflon nonstick they can tolerate a little more high temperatures than the Teflon non-stick pans.
7. Avoid chipped or damaged pans
Metal utensils can cause chipping and flaking. Such non-stick pans can likely release more toxic gases. Use wooden or silicon utensils, avoid abrupt temperature changes, and stacking, and use a soft sponge to clean. If a pan is scratched or damaged, replace it.
