Das Tagebuch Murnaus

"foodstuff" is defined in the dictionary as "a substance used as food". So I suppose this, by extension, applies to items adulterating real food, like the fine sawdust they used to put in British sausages during the war. Or maybe it could include items eaten as food but indigestible by the body, like the fibre drinks old and constipated people consume here, or things like Olestra, a chemical that helps people lose weight but also makes them leak from their asses....ugh.
