a while ago, slightly before reality shows totally inundated the airwaves (ok.. maybe that time never existed) there was some show about a group of folks who were doing like one of those PBS style 'live like the old timey people from the pioneer days' type shows...
for some reason some vegetarian person volunteered to be on this 'survive the winter in frozen tundra' show, like a gold prospector or trapper in the yukon might have done..
at first the person was surviving by eating a whole winters supply of peanut butter.. along with other stuff (they had all their shelf stable food for the winter with them and had to survive by supplementing meat/fish they hunted)..
within a short period of time, the person was eating the hunted meat...
im guessing they coulda have left at any time.. but just wanted to do things as best they could..
of course, it was on TV, and it coulda totally been fake.. it sure seemed legit at the time..
it seems to me that our modern food supply system really enables both the meat eaters.. and the vege people to eat lotsa stuff theyd never have been eating regularly 200-300 years prior.
thanks to safe refrigeration and rail in the mid 19th century we got fresh meats to the cities.. and all of the benefits we enjoy today, like fruits and veg year round, in season or not, shipped from all over the planet (along with keeping things frozen for months at a time!)
thanks to canning and bottling and pasteurization in the early-mid 19th century we got stuff that can live on a shelf for ages without needing anything to keep it edible! magic!!! ..vegetables, fruits and meats can travel in our knapsack
thanks to all kinds of fancy baking magic we dont need to eat
hardtackanymore!!.. our bread can last a week or longer..
i was once reading about how things were in 17th century england.. among the elite, gentry and nobles it is mentioned about how it was basically unheard of/impossible to be a vegetarian in those days because people were so suspicious and superstitious about things like fruits and vegetables...it just wasnt something that one would consider in any way...... if they were to eat any fruit/veg itd be apples, plums.. or cherrys.. this was back in the day when drinking water could easily kill you and most people drank beer or wine though... centuries before modern medicine and a time when eatin the wrong thing on the wrong day may end you up in prison.
