Christ and all Jews wered to eat Lamb on Passover. It was required for the Passover ritual. Christ also ate fish. These people lived where fish was abundant. The object is health. Did they have a lot of vegetables and fruit to eat? Not always. Only during the growing season and then they dried the fruit. They did not have canning yet! There are times when you have to eat what is available, but they ate according to the clean meats. Also, How often did they eat meat? I doubt that it was every day, 3 times a day. They basically grew their own and had to have the animals for sacrifice, that took precedence over their stomachs. Their fish did not live in polluted waters loaded with mercury. Their animals for food were not loaded with hormones. The killing of the animals were specific and they had to be disease free. Nowadays, they throw everything into the "killing fields". Animals are treated cruelly and live in huge crowded places without access to pastures--and the pastures that they had were not treated with pesticides. Even their wine was different. Not loaded with all sorts of chemicals, nitrites--and again, the grapes were not treated with pesticides. Their cattle were not huge holsteins, there are some cows still raised in Israel that are of the old type. They are small compared to what we're used to. They also ate goat. The cheeses they had were mostly made from milk from goat, and sheep and some oxen and a few cows. They also had some venison. All were much healthier and lived in pastures or in the wild. Nothing like what we have today. And when you have to catch, and kill your own animals for food--you just don't want to eat that much of them! You get attached to the critters! It's tuff to kill and hard work to butcher. We had one whole lamb that we bought and had to cut up--it took forever and it was hard work, and we had a freezer to through it into. We did it one time only--It was just too much, took hours! Fish is easier and you don't have the fur and feathers, just some scales! My brother had a bunch of chickens, one in particular was his favorite, yes, Henrietta!! She'd roost on his shoulder--no way would he eat her!! And kids get even more attached to animals. To see them on the dinning room table is traumatic! I would not eat the pidgeons that my father would occasionally butcher--they were pets, they had names, I had to feed them. He had over 200 of them, he'd let them out they would flew around and then return home. Great to watch--they mated for life. Petunia ended up on my plate and I almost threw up!!
