Interesting reading for those who think humans are omnivores...
The problem with that is, early humans were hunter gatherers, meat fruit and insects, that makes us a true omnivore.
moving forward, they started to use tools to kill meat, therefore our tooth formation was for ripping (Incisors)
and the molars are for grinding. once we discovered fire, the teeth formation slightly changed.
And through the course of evolution there was little use for true canines
Now look at true carnivorous, the canines are extended, these are used for holding and killing..
The rest as above.
And that includes monkeys, who actually do eat a lot of meat. ( and insects and berries)
Cheese or bacon? now if I want a quick sarnie, as a fully fledges card carrying omnivore that is a tough call

I know that vegetarians have been around a long time, but I also remember when it became "Fashionable"
Late 60's / early 70's.
And I also remember being able to pick them out of a crowd, due to the pallor of their skin, Mostly it seems because they didn't understand the
difference between 1st and 2nd class protein.
Thankfully these days, there are much better foods available, for veggies.
And they are getting a much better balanced diet.
I have no problem if people want to be veggies whatsoever, just as long as it doesn't become compulsory
Although what I do object to, is those that take the moral high ground, tell everyone how "good" they are, but still eat chicken / fish.
