To be a healthy vegan you have to at least have half a brain.Buffy has forgiven me for jumping off my vegetarian diet, which I persisted with for several years. I treat her extra well as penance. I dropped the diet because at my age, late 50s, i was dropping muscle mass severely and skin was drooping all over the show. Back to lean meat, I am much stronger and alert, and don't suffer any digestive issues at all. The vegie diet was much tougher on the innards.
I was years ago advised to feed my kids meat to assist brain development. I see this is still advised by many health authorities. Meat is chockers with essential vits and minerals, in a tasty neat package, easily digestible, and the lack of it at early ages, and perhaps in later ones, may inhibit health.
It's worth noting Buffy is also a meat eater, how hypocrital of her to point the paw at me.
Compounding vegetables to achieve the correct nutrition isnt as easy as just eating meat and 3 veg.
