#1 – Teflon cookware
Teflon is many people’s first choice because it is very convenient, but unfortunately, it is the most dangerous one. The non-stick material of this cookware is achieved with a PTFE coating (polytetrafluoroethylene), and it is a plastic polymer that leaks toxins if the heat is over 572°F.
These fumes can lead to polymer fume fever, which is a flu-like symptom that’s known as the Teflon flu. However, it is not that dangerous on humans, but it is fatal on pet birds.
Moreover, the Teflon cookware has another chemical compound called PFOA (perfluorooctanoic acid), which is associated with many types of cancer as prostate, ovarian, and breast cancer.
It is believed that this chemical is present on this cookware in small amounts, but it still exists in many other things that we use daily. So it is best to limit our exposure to it as much as possible!
The better alternative: Iron cookware (real cast). It is very safe and remains that way for a long time. It can be heated and even seasoned to become non-stick. Nothing toxic will be released to your food and it is considered as a natural way to boost your iron levels.
In case your iron levels are good, then you can use the enameled cast iron cookware because it is as convenient and safe as it should be.
