It’s easily possible to eat a ‘normal’ diet that excludes meat. I don’t eat meat myself, and am revolted at the thought of having to touch the flesh of mammals, but if I had children, they would certainly be eating fish and fowl regularly although the emphasis would be on legumes and nuts.
And I think that’s sensible. What an adult decides for themselves is one thing. Growing brains are another. FWIW I think most folks feed their kids way too many refined carbs as well.
OOps...sorry, I posted before I finished. A “normal” human diet includes animal proteins, so it’s not really possible to eat one that excludes it. I’m sure you eat that way, and I don’t doubt you’re healthy, but it’s not what you evolved to eat.
