You know that lifestyle where everyone was poor, sickly and died at a younger age, that's a totally better lifestyle!
Here's some stuff they conveniently left out that my Polish grandparents told me. In that lifestyle you may eat the clean meats on special occasions, but you eat the less desirable parts on a regular basis. Mostly in soups and stews because it stretches the food for longer. You save the bones and make soups out of them. Oh and you ate a lot of fat. Like smearing pig fat on bread. Technically pork was the cheapest meat. Only one purpose animal. Hens give eggs and fertilizer. Cows give milk, fertilizer and pull carts/plows. Kill them only when they're useless. Plus you may get meat from a butcher on special occasions. People hunted a lot back then. Rabbit, deer, etc. So, they would supplement game for livestock. Because game meat is not considered desirable by civilized society.
Oh and fish. In eastern Europe, fish. Like always. It's cheap as shit and plentiful. It's also not considered meat because of Lent. Which is stupid. Fish is meat. Grow up. That's why people say they don't eat meat, but still eat fish. It's a catholic concept.
The idea that the old world ate less meat is misleading. They ate less prized meats. Today we consider top round off a cow as a cheap cut. That use to be a Christmas roast for many poor families.
Vegan diets are being proved by lots of studies at being pretty shitty for you. Even when I did it with my then girlfriend for a year. My bloodwork went to total shit and I always felt like crap.
This whole article and crap is just a bunch of power hungry assholes in the UN appeasing to childish hippies who never picked up a book outside the metaphysical section.
