Where does 84% come from? Would love to see a cited source, so I can understand your point better.

Re: health without meat & dairy: B12 and other vitamins missing in vegetables are also missing in our meat, which is why all chicken, pigs, and cows are fed B12 vitamins in their feed.

If you stop eating meat and dairy all together, you have to supplement B12 - but most Americans are B12 deficient either way, similar to vitamin D.

Finally - eating meat and dairy also leads to health problems, see: heart disease. I know it's complex, but dairy is definitely not a required part of a diet, and is why humans don't feed their young human milk after infancy.
