Non-Stick Pans: Are Pfas Inevitable?

Non-stick pans are coated with PFAS (per- and polyfluoroalkyl substances), also known as forever chemicals due to their persistence in the environment and human bodies. PFAS gives non-stick pans their characteristic slippery surface, but it has also been linked to various health issues, including certain cancers, reproductive issues, and high cholesterol. While not all non-stick pans explicitly contain PFAS, they may still contain other PFAS chemicals that fall under the broader PFAS category. It is important to note that the health effects of low exposure to PFAS are uncertain, and ongoing research is investigating how PFAS move through the environment and impact human health.

PFAS chemicals are linked to higher health risks, including certain cancers, infertility, and liver disease

PFAS chemicals, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals that are widely used in non-stick cookware due to their ability to create a non-stick, slippery surface. While PFAS chemicals offer these desirable characteristics, they have also been linked to an increased risk of various health problems, including certain cancers, infertility, and liver disease.

PFAS chemicals have been shown to build up in the bodies of humans and animals over time, and studies have indicated a correlation between higher exposure to PFAS and an elevated risk of health issues. The specific types of cancer that have been linked to PFAS exposure include kidney cancer, testicular cancer, thyroid cancer, prostate cancer, bladder cancer, breast cancer, and ovarian cancer. In addition to cancer risks, PFAS exposure has also been associated with infertility and liver disease.

The two most commonly used and studied PFAS chemicals, PFOA and PFOS, have been phased out in the United States due to concerns about their persistence in the environment and potential toxicity. However, other PFAS chemicals are still in use, and their health effects are less well-known. While non-stick cookware may not be a significant source of PFAS exposure, it is important to be aware of the risks associated with these chemicals and take precautions to minimize exposure.

To reduce the potential health risks associated with PFAS exposure, individuals can take several measures. Firstly, it is recommended to avoid using metal utensils on non-stick cookware to prevent scratching the coating, which could allow PFAS to migrate out. Secondly, it is important to not broil or use non-stick skillets at temperatures above 500°F, as high temperatures can cause the non-stick coating to degrade and emit toxic fumes. Lastly, always heat non-stick skillets with oil or butter to provide a visual cue that the pan is getting too hot and to prevent overheating.

Non-stick pans are coated with a polymer form of PFAS called PTFE

PTFE is a synthetic chemical that is characterised by a strong carbon-fluorine bond, which makes it resistant to degradation in the environment and gives it non-stick properties. While PTFE itself may not be harmful, the presence of other PFAS chemicals in the coating process can be a cause for concern. Some studies have shown that non-stick coatings can degrade and emit toxic fumes when heated to high temperatures, potentially causing health issues.

It is important to note that the risks associated with PFAS exposure from non-stick cookware are not fully understood. The FDA allows PFAS to be used in non-stick cookware, while the EPA has stated that exposure to PFAS can lead to adverse health effects. The CDC has also stated that the health effects of low exposure to these chemicals are uncertain.

To minimise any potential risks, it is recommended to avoid using metal utensils on non-stick pans, as they can scratch the coating and potentially release PFAS. Additionally, it is advised not to broil or use non-stick skillets at temperatures above 500°F (260°C) to prevent the degradation of the coating and the release of toxic fumes.

While non-stick pans may offer convenience and easy cleanup, there are alternative options available, such as ceramic, carbon steel, and cast-iron pans, which provide a non-stick surface without the use of PFAS. These alternatives may require more careful cleaning and maintenance but can be a healthier and more environmentally friendly choice.

PTFE is typically made using several hazardous PFAS chemicals

Non-stick pans are made with PFAS (per- and poly-fluoroalkyl substances), which are synthetic chemicals that do not appear naturally in the environment. PFAS are made up of a carbon-fluorine molecule bond, one of the strongest bonds in chemistry. This bond is what makes non-stick pans, well, non-stick.

PTFE (polytetrafluoroethylene), also known as Teflon, is the PFAS that is used to make conventional non-stick cookware. PTFE is typically made using several hazardous PFAS chemicals. In the past, PTFE was produced with the help of another PFAS called PFOA, which has been clearly linked to health risks. Due to these concerns, PFOA was phased out in 2014, and now PTFE is produced without PFOA in the United States.

However, PTFE still contains other PFAS chemicals, and there is ongoing research about how these chemicals move through the environment and affect human health. While some sources state that there is no evidence that using PTFE-coated non-stick cookware is harmful to consumers, others argue that PFAS should be regulated as a single class in drinking water and the environment to simplify the process of evaluating toxicity.

PFAS chemicals are also used in waterproof or stain-resistant products like clothing, carpets, and cosmetics

PFAS chemicals are used in a wide range of waterproof and stain-resistant products, from clothing to carpets and cosmetics.

In clothing, PFAS are used to make items water- and stain-resistant. This includes rainwear and other waterproof clothing, as well as children's textiles labelled as "waterproof", "stain-resistant", or "environmentally friendly". A study by the Silent Spring Institute found PFAS in 54 out of 93 such products tested, including 21 with "eco", "green", or "non-toxic" labels. The chemicals were most commonly found in products labelled "water-resistant" or "stain-resistant".

PFAS are also used in carpets and other home textiles to make them resistant to water and stains. However, some companies, such as Home Depot and Lowe's, have removed PFAS from their carpets and rugs.

In cosmetics, PFAS are used to create water- and stain-resistant properties. Several cosmetic brands, including Beautycounter, Credo, Sephora, and Whole Foods Market, have committed to removing PFAS from their products.

PFAS, or per- and polyfluoroalkyl substances, are a class of synthetic chemicals that are highly resistant to degradation in the environment and within living tissue. This has led to them being dubbed "forever chemicals". While PFAS have a variety of useful applications, they have also been linked to a range of health problems, including cancer, birth defects, liver disease, thyroid issues, decreased immunity, and hormone disruption. As a result, there is a growing movement to regulate and phase out their use in non-essential products.

Safer alternatives to non-stick pans include ceramic, cast iron, carbon steel, and stainless steel pans

Ceramic

Ceramic pans are coated with natural materials, usually sand-derived silicon. They are PTFE-free and won't release toxic fumes if overheated. They are also more affordable than traditional non-stick pans. However, they are less durable and need to be replaced more often. They are also not the best choice for searing and browning as the surface doesn't provide a "grip" on food.

Cast Iron

Cast iron pans are highly durable and can last for decades when cared for properly. They can be used on all types of stoves, in ovens, under broilers, and on grills. With proper seasoning, cast iron pans develop a natural non-stick surface. They are also very affordable. However, cast iron pans are heavy, heat slowly, and require extra maintenance. They are also reactive, so cooking acidic foods should be avoided as this can strip away the seasoning.

Carbon Steel

Carbon steel pans are lightweight and affordable. They require seasoning but, when done properly, offer a non-stick surface. They can withstand high temperatures, unlike traditional non-stick pans. However, carbon steel is reactive to acidic foods and requires more maintenance. They are also not as slick as PTFE-coated non-stick pans.

Stainless Steel

Stainless steel pans are durable, versatile, and can last a lifetime. They are non-reactive and require minimal maintenance. They heat up quickly and are compatible with all cooktops, including induction. However, they are expensive and food can easily stick to the surface. They also take more effort to clean compared to non-stick pans.
