From gidmkhealthnerd, a scientific fact-checker: Counterpoint: this seems to be the crusade of a single researcher - I don't find the data personally convincing and am still using my black spatula for cooking. https://www.threads.net/@gidmkhealthnerd/post/DBxbQERykRx?hl...
Also, plastics have quality grades from "that's good stuff" to "this thing smells funny in a bad way". We have some IKEA food tweezers which use black plastic molded on steel prongs. It's stamped with "+150 degrees C" and the black is hazy, like it's colored with a dye or pigment, and plastic is hard like bakelite.
OTOH, I have used other "black" spatulas which are uniform in color, but neither as sturdy, nor smell neutral.
We have silicone counterparts to these items too. They're more rubbery, but they have hard plastic spines inside so, they don't flex.
