lol
well, you can get a lot of those proteins and fatty acids from beans, and nuts, and they did have soy beans i'd imagine back then. i'm not a vegan or anything but i know my fair share about it cause my mom was a vegetarian for years and this chick i just stopped fuckin is a vegetarian. lol.
but, you don't "need' meat to live. you can get the exact same minerals, nutrients, etc from other sources.
you don't have to eat meat to be healthy. in fact, most of the meat we do it isn't healthy for us. especially today. red meat, is not good for you to eat more than 1-2 times per month. the tax payers just happen to fund the cattle industry so we get it for cheap....if the taxpayers didn't fund the cattle/beef industry, we'd be paying
$30 for ONE pound of ground beef.
lots of stuff is like that. i'd rather eat tofu than beef to be honest....i grew up eatin tofu and stuff like that cause my mom was/is a hippie type and she was a vegetarian....
but...like i said....you could survive on a lot of shit that's not meat...even 1000 years ago. they did have crops of foruit and vegetables etc. i do believe that the Egyptians had them....hense crops by the Nile...and it flooding each year and them planning for it. that's long before 200 AD
