Teflon became popular because it is non-reactive due to its strong carbon–fluorine bonds; it reduces friction and energy consumption of machinery when used as a lubricant. Though it was claimed to be the best-known chemical inventions of the 20th century, today, Teflon has been touted as a serious health hazard to humans as well as animals. When I found out about the dangers of teflon, I transitioned over to cast iron and stainless steel pots and pans. The research behind teflon is dangerous and jarring.
Non-stick cookware may cause cancer
The non-stick coating, used in Dupont Teflon pans, has been found to release one or more (up to 15) different toxic gases when heated to high temperatures. Did you know that non-sick cookware is made with a chemical known as perfluorooctanoic acid (PFOA), which has been labeled carcinogenic by a scientific review panel that advises the U.S. Environmental Protection Agency (EPA).
This is a chemical that is being used in many household products from cookware, coated paper plates and even microwave popcorn bags. The side effects have been known for a long time, and one of the most written about is its effects on pet birds.
The worst issue behind Teflon pots and pans
As careful as we try to be – Teflon pots and pans can easily get scratched at some point. In fact, the truth is many people tend to use battered and scratched Teflon cookware. Teflon is usually used to cover aluminum which in itself is a dangerous metal – implicated in Alzheimer’s disease and dementia.
What are some of the health hazards faced?
- Male Infertility- The chemicals emitted from the heating of Teflon pans have recently been shown to be linked with higher rates of infertility. A recent Danish study suggested that exposure to PFOAs in fetal or later life accounted for decreased sperm production and morphologically abnormal sperm.
- Thyroid disease – A recent study, published in the peer-reviewed journal Environmental Health Perspectives (EHP), goes on to confirm the association of thyroid disease with human exposure to perfluorooctanoic acid (PFOA). Also the National Health and Nutrition Examination Survey (NHANES) revealed that higher concentrations of PFOA in the blood of the surveyed people were linked to the occurrence of thyroid disease.
- Childbirth and reproductive problems – PFOA contamination of food, air and water supply has the potential to damage the reproductive systems of a large population of women. Inevitably causing difficulty in childbirth or birth defects. Scientists based at the University of California-Los Angeles, found that women with higher concentrations of PFOA in the blood stream (more than 3.9 ppb) experienced greater difficulty in conceiving than those with lesser PFOA concentrations. Also the chances of them being diagnosed with infertility were greater.
- Birth Defects – an individual living near the DuPont factory that produces Teflon products was born with one nostril and other facial defects. He claims that his mother who was working in the factory was exposed to PFOA while pregnant therefore he acquired those birth defects.
- Kills bird – when Teflon is heated to a high temperatures toxic fumes are emitted that are known to kill pet birds especially small birds such as budgies, finches, and cockatiels. Considering this the Consumer Product Safety Commission (CPSC) states that cookware and heated appliances comprising of non-stick coatings must carry a label that warns the hazard caused by the coating to pet birds.
- Carcinogenic – a recent study showed that when rats were injected with PFOA they developed brain tumors. PFOA the coating material used in Teflon products was also shown to be present in trace amounts in blood samples of people and lasted four years in the blood stream.
- Causes other diseases – animal research has shown that liver cancer has propelled with more exposure to PFOA’s and case reports suggest that the PFE fumes emitted by very hot Teflon coated utensils have caused pneumonia and inflammation in the lungs.
- Non Biodegradable – PTFE is non-biodegradable as it is made up of strong molecular bonds that make it durable and resistant to natural processes of degradation. Thus it tends to accumulate in the food chain causing sever damage.
How to avoid these circumstances?
The best way to protect you and your family is to use cookware made from: ceramic, stainless steel or glass. There’s clearly no argument as to whether conventional non-stick cookware has a negative impact on human health, so with that in mind, what are the alternatives?
Ceramic cookware is gaining popularity fast thanks to its ability to create a non-stick cooking surface while containing no traces of PTFE or PFOA.
Brands such as Neoflam are using the most advanced ceramic technology to produce durable and heat efficient non-stick coatings that are safer and more environmentally friendly than conventional non-stick cookware.
2. Cast Iron
Companies like Solid Teknics are manufacturing some incredibly high quality cast iron products which have a myriad of advantages over conventional non-stick cookware.
Cast iron is extremely rugged, easy to clean, and if properly seasoned, it’s also “non-stick” (minus the toxic cocktail of chemical compounds). Cooking with cast iron is a great way to experience many of the benefits that come with using non-stick cookware while also minimizing your exposure to harmful substances.
3. Heatproof Glass
Glass isn’t the most dynamic cooking material and it’s somewhat limited in the styles of cooking that it can accommodate, however, for oven baked dishes there aren’t many materials more safe and affordable than heatproof glass.
When choosing glassware for cooking, be sure to check that the glass is heatproof and of high quality construction. Pyrex has a great range of kitchen glassware for all sorts of different applications, including cooking.
Similar to ceramic, stonewear cooking equipment is a non-toxic alternative that usually involves a combination of crushed stone and a PTFE-free coating in order to achieve similar results to those of typical non-stick cookware.
Brands such as Stoneline, Swiss Diamond & Ozeri all provide good products in this range.
5. Stainless Steel
Tried and tested, stainless steel is one of the safest cookware materials in existence and is an excellent non-stick alternative for many forms of cooking. It’s worth noting that using frying pans and skillets that are made from stainless steel will sometimes result in ingredients sticking to the surface of the cookware when exposed to high temperatures. However, if you use ample amounts of a high quality cooking oil, you shouldn’t have too much of a problem.
