Yup, all food is death. Vegetarians and vegans are just picking their ethical battles, really. I sometimes idly wonder things like how far we are from sci-fi synthesis of a complete diet from entirely inorganic materials that have never been in a living thing. It might even become a necessity as a spacefaring species. Although, humans separated by interstellar distances would almost certainly diverge to the point where maintaining a single “species” becomes dubious, even if you had constant interbreeding, so you might have humans eating local plants & animals on other planets that are nutritionally useless or hazardous to Earthlings.
