Quote from armoured saint:
it's a misconception that only meat has all the essential amino acids. ALL PLANTS contain ALL ESSENTIAL amino acids too. but ONLY beef has artery clogging saturated fats and cholesterol
Saturated fats don't clog your arteries, it's the unsaturated fats that primarily do. But you won't have the USDA tell you that since soybean & corn industry is a major lobbyist.
Real beef, that's grass fed & graised, has very little saturated fat in comparison to commercial raised beef. The nutrition is unmatched by plantlife when you realize how much grass a cow eats.
Get off your vegetarian tirade and try learning reality behind human diets. Maybe check out the Hunzas, who eat beef & pork and smoke and drink, yet are ultra healthy. The answer is elsewhere.
The fact is that the human digestive & food delivery system is one of a omnivore, not a pure herbivore or carnivore.
