Great read, and the healthiest approach by far! I don't think anyone here would have the stones to refute genuine study information, in fact we rely on it for support of our overall fat-heavy, low-carb ways.
While it is sad that most paleolithic foods are no longer unavailable for the most part, our modern equivalents are the best we can do. But I don't understand the exploration into rice or butter. I mean, why? You have raw grass-fed fat and sweet potatoes, that's more than enough!
As for the timeline awareness, it is powerful! The lack of records from our days in the original environment, with the many failed lineages thereafter sure brings a new perspective to the whole deal. But it doesn't change my desire to eat just the way I am, because science and the history we do have both support it!
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
