Mark your words?

You talk about being in the nutritional dark ages then mention eating fresh animal meat

No evidence exists anywhere that human beings should consume meat. Our digestive tracts are 4X longer than any other animal that consumes meat (which leads to rotting flesh in our body (not ideal)) and in repeated tests the sight and smell of fresh meat fails to incite child salivary glands but fresh fruit and vegetables does.

Unlike actual carnivorous animals which are equipped with the teeth, claws and digestive means to eat meat. Young offspring naturally hunt other prey and salivate at the prospect of flesh/organs.

To paraphrase yourself - mark my words, we will look back on the human consumption of meat with the same horror that considered bloodletting as a medical practice.

Disclaimer - I eat meat despite the huge risks to my wellbeing.

Test - Leave a toddler in a playpen with a rabbit; trust me he won't attempt to fucking eat it. He has not been social conditioned to see the consumption of meat as normal.

Leave an omnivorous or carnivorous animal in a locked environment with the same rabbit. You will need a new rabbit.

Have you ever been involved in the process of growing food? A workday on the farm is substantially longer than any office job, the only way to talk to people is to scream because they're at least thirty meters away from you most of the time. At the end of it you're drained and people who have been doing it all their lives get to live the last years of their lives with terrible back pains and having to rely on the young folks for, um, growing food, because it turns out doing manual labour for twelve hours a day isn't so easy when you're eighty. There's anything but quality time in that.

Edit: It also turns out that, with foodstuffs having to be so cheap, this kind of work was also very badly paid, which meant that except for people who owned huge amounts of land (and generally didn't work all, or more commonly any of it), people who had to do this were, if not dirt poor, in any case poor enough not to be able to afford too much. It's the fact that we lost all this chance to have "quality time" that allows us to heartily debate such matters through silicon stuff that shoves charge carriers through really thin glass tubes.

Preparing food was a major source of such "quality time" as peeling, flaying, cooking and serving food for a large family. Quality time, indeed.
