Here are my favourite cookware products and top approved non-toxic products. Please also do your own research to make the best decision for you and your family.
My top choice is the DaTerra Cucina.
DaTerra Cucina will last longer than GreenLife, but GreenLife or Xtrema is a good starting point if the price is limited.
Note on GreenChef, GreenLife, and GreenPan: they are sister brands of the same company called Cookware Company. They all use Thermolon for non-stick coating. GreenChef and GreenLife say that most of their cookware is made from aluminum. GreenChef also has a coated stainless-steel cookware collection, and GreenLife specifies that they use recycled aluminum.
Note on stainless steel products: make sure you are buying cookware made with a food-grade version of stainless at the very least. Stainless steel is a mix of metal including carbon, chromium, nickel and/or manganese. Food-grade stainless steels include 304, 316 and 430. There’s also the specification of 18/8, 18/10 or 18/0 stainless steel.
