You actually can get all of those nutrients from plant foods, or your body creates it - as in the case of Taurine, Carnosine, and all other "non-essential" amino acids.

The only exception is Heme Iron (the less bio-available form of iron)

Anyway, there's a BIG difference between "going vegan" (mostly green-brain-washed folks who still don't eat organic, whole foods, or cut out the poisons) - and actually eating a healthy plant-based diet.

Bill Gates wants everyone to be a Beyond Burger & french fries type of vegan. Cut out the animal products, replace them with laboratory-made food replacements, and that achieves 100% control over the bodies of the masses.
