I like how DUmbasses are all 'science' until its science they don't like.
We evolved from meat eating apes, and as such, we require nutrients meat gives us. For example vitamin B12. Long term deficiency results in all sorts of issues. So, many vegans rely on 'Big Pharma' (Which you DUmmies are supposed to hate) to produce artificial substitutes that come in pill form, or in breakfast cereals.
So - vegans are denying their own evolution to embrace this ridiculous notion of peace and harmony with all living things.
In closing DUmmy, get yourself some peel & eat shrimp with cocktail sauce, a big fat steak with a fried egg on top, and wash it down with a glass of whole milk. It will do you good. -- And STFU.
