because of the mechanisms and pathways of production of both groups and the hundreds of thousands of years of evolution that make us omnivorous and evolved to source our iron and Bvits from meat. Yes, it's entirely possible (if difficult) to obtain iron and Bvits from non-animal sources, but only by taking supplments of synthesied vits, particularly cobalamin. Which, of course, is totally natural and healthy. But, yeah, I'm clearly the one being sancitmonious.

And there is still an awful lot of debate as to whether it's anywhere near as effective as the animal-sourced version.

I was questioning your claim about iron and the other B vitamins.

B12 is the only one that's impossible to source naturally except from animal products. Iron and other Bvits are harder to source from non-animal products. Particularly iron, as in greens particulalry it exists in a form that we haven't evolved the mechanisms to absorb yet.

Sure, I would need to consume a much larger quantity of cruciferous vegetables to get the same iron as a small cube of red meat, but likewise, my body doesn't really require the iron that a 12oz steak would provide.
I'm not some anaemic, menstruating female.
Nor does the B12 worry me, I'm pretty sure I do not have pernicious anaemia either.
