Iron is just a mineral, where do you think the cows get it? Plenty of plants have iron. Meat is also typically a lot more expensive than rice and beans. Like you want to eat meat, that's cool, just stop acting like it's for your health when meat is literally a carcinogen.

Nails have iron, try eating one of those! The air is mostly Nitrogen, why do plants even need N2 in the soil?
It's basic fucking science that nutrients take different forms which can be absorbed differently.
Again: where do you think the cows get it, lol. Not from nails.
