I'm not here to argue. Simply offering my perspective per the OP's request. That does not take away from the fact that almost all plant-based protein sources lack "complete" proteins with all of the essential amino acids that the body needs for cellular repair/regeneration. There are plenty of long-term studies that underscore this.

I am not challenging the merits of vegetables, as I realize they are absolutely essential for optimal health. One needs at least a moderate source of protein and fats with a plentiful source of vegetables to support a healthy metabolism.
