> Meat provides far more nutritional value than any plant

Bullshit, the kind of lies that the meat industry loves to spin.

Nutritional value is not one single measurable thing. And even protein contents (meat's most common nutrient) when measured per gram can be higher in soy and derivatives than in some meats (e.g: pork but and shoulder). When measured by calories other legumes (beans, chickpeas, lupini) beat most meats.

The only nutrient not often found in plants is B12 vitamin. But it can be bought cheap as a nutritional supplement.
