I don't agree with your version of human history in this ancient past of being of primitive's who 'discovered' agriculture. The knowledge of ayurveda (vedic health texts) and other vedic texts don't suggest they were primitives but rather people with advanced knowledge. In Vedic epistemology there are 3 ways to ascertain knowledge, your senses, inductive logic and hearing from an authority. There are detailed descriptions on the theory of food, medicine and the functioning of the body. The reductionist view of counting calories and chemicals in a laboratory will never come up to it's standard because the human body is far more complex.
