I don't know - my mom and dad both subsistence farmed in Poland in the 50s through 70s (and largely never stopped). For sure we had to eat weeds (I continue to), and sometimes steal some "not great" potatoes or other vegetables or fruits. Don't knock it till you try though, those "weeds" are often waaaaay more nutritious than the store-bought bullshit, and often much more delicious. Unfortunately, often those 'weeds' were cultivated by a single family (and kept in the family and protected as a secret to surviving the next big one), and now they're nothing but a memory.
