Titanium, teflon, iron or ceramics? Each nonstick surface has its benefits and cons, with teflon being the one with considerable concerns about health, and how it usually happens, the cheapest option.
Iron based surfaces provide an additional intake of this periodic element, something that should be positive. They are common in professional cooking and have a good nonstick ratio or sometimes excellent. A surface of this kind doesn't handle too well water due to oxidation, and could be scratched if the user doesn't take the appropriate measures. With an alloy, the resistance to oxidation is much higher or almost complete with a normal use in the kitchen.
Titanium is also commonly used for cooking, with perhaps higher price but obviously more resistance too as this material is one of the hardest known. Nice nonstick capability and like iron and ceramics the user could forget the potential added toxicity of teflon based surfaces.
Ceramic surfaces are another option. This material is prone to scratches and requires care to retain the nonstick property. Ceramics and teflon inexorably lose the nonstick action with time, so they aren't forever. Titanium resists more than others.
Teflon surfaces seem the most used today, with the usual black or dark gray color. There are many sources citing a high degree of toxicity due to this artificial element or others trying to imitate the same characteristics. Some manufacturers do a regrettable work when producing the units as the surface is very thin and easily detached thus it's prone to being part of the meal in high proportions.
If the nonstick material gets lost with time, where does it go anyway? Our advice is to focus ceramics, titanium or iron based surfaces. Ceramics, teflon and titanium have the problem of waste, singularly the first two. They are a layer over other material usually aluminum, and it's not recommended using the surface if the aluminum is visible, due also to the possible toxicity. Iron surfaces with a sophisticated treatment ensure the best inversion as they could last decades without producing plastic waste, aluminum, synthetic chemicals or materials to recycle in the best case. Not always as it depends on the responsibility of the brand and the legislation. A well produced titanium surface could last up to decades as well.
