I didn't say "humans were never obligate omnivores"
Yes, actually, that is what you said. That may not be what you meant, but it is exactly what you said
It isn't what I said. What I said, from
post #361:
"we aren't obligate omnivores"
"Aren't" is present tense.
The fact that we can substitute one source of an essential nutrient with another created through the use of modern genetic engineering technology does not change human physiology
Indeed. Nor would "there are no non-animal sources of B12 in our environment" say anything about human physiology. So clearly it is not physiology alone that is relevant, but the relationship between the body and the environment. In an environment in which non-animal sources of B12 are available, we are not obligate omnivores. In my view. Granted, not all humans have access to B12 supplements, so some do need to rely on animal products.
But this is merely a definitional disagreement and of no importance substance-wise.
any more than the fact that we can create dialysis machines mean that humans do not need their kidneys. "Choosing" a different diet does not change human physical reality, it merely means that extraordinary efforts are required to make up for the deficiency of a particular diet.
I can buy a year's worth of B12 for 10-15 dollars. I wouldn't call that an extraordinary effort. Much less work/resources go into it than go into a year's worth of animal food products.
It also helps to keep in mind that not everyone in the world has access to the same resources and technological products as privileged First-World denizens.
Granted. I addressed impoverished people and hunter/gatherers earlier in the thread.
Incidentally, there are people who insist on trying to raise their dogs and cats, both obligate carnivores, on purely vegan diets. It works about as well as one my reasonably expect (ie. not very well at all).
I don't know the research on that, but if it doesn't work well then that works against Belz...'s claim.
You'll excuse me if I prefer actual medical science over your "view".
I hope you have a nice day.
You're moving the goalposts. That was never part of your original argument, nor was giving Han to this bounty hunter! Woah. Sorry about that.
Again it's a definitional disagreement, not an argument. And clarifying is not moving the goalposts (not that there even are any goalposts).
As well as we, I'd think.
luchog seems to disagree. I don't have a view to offer myself, not having looked at the research.
