I knew going in this was going to be a tricky one, because dairy, especially raw and/or fermented full-fat dairy, resides in a Primal gray area. The literature, the evolutionary reasoning, and the anecdotal reports all unanimously point to sugar, cereal grains and legumes, processed foods, and industrial vegetable oils as being net negatives on the human metabolic spectrum, but dairy is somewhat different. The other Neolithic foodstuffs we can rule out because the science condemning them is fairly concrete and they weren’t on the menu 20,000 years ago. Heck, they weren’t just off the menu; they were basically unrecognizable as food in the raw state. Dairy, on the other hand, 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?
