I’m not necessarily disagreeing with your conclusion, very likely eating meat is less bad than drinking e.g. Coca Cola (but FWIW I’m not a nutritionist), but your premise is wrong: just because we evolved doing something doesn’t mean it’s not bad. It’s a classical „appeal to nature“ fallacy.

Nature doesn’t care about your „health“, it just needs you to be able to reproduce. Now with regard to humans we’re able to reproduce at age ~11-14y, but we also do need to take care of our offspring (roughly) the same time, so that would put the needed lifespan of any given human being at ~25y. Give or take, just trying to make a point here.

But we are able to live much longer than that, in industrialised countries we’re clocking in at >80y, so being and staying healthy at that age is not something that evolution prepared us for.

Having evolved to eat meat doesn’t mean anything beyond the reproduction timeline.

(Also, the poster above was making a point about industrial animal husbandry being one major factor to climate change, so it goes beyond human evolution.)
