Dairy, is a relatively recent food chronologically, but it is most assuredly and obviously a viable nutritive source in its raw form. It’s full of highly bioavailable saturated fat, protein, and carbs – in equal portions. You could conceivably survive on milk alone (I wouldn’t recommend it, but you could technically do it; try doing the same with honey or raw millet). Milk is baby fuel. It’s literally meant to spur growth and enable a growing body. Our bodies definitely recognize dairy as food, even foreign bovine dairy. But is it good nutrition?(This Mark's Daily Apple article was written by Mark Sisson, and is narrated by Brock Armstrong)
