RE: The substance of these nutrients in your meal must be known to you, and this knowledge is critical.

I think there's more agreement in what nutrients we need than in what those nutrients should be packed in. Some argue against meat, others against dairy (more than 50% of the human population has issues with lactose), others against grains . . . we know what nutrients we should eat, but we don't know what we should eat them as!
