It’s almost time for the Ancestral Health Symposium . I’m looking forward to seeing friends, meeting lots of folks, and listening to so many of the people I’ve been learning from these past few years. I’ll be presenting a poster on Saturday, August 6 th . A marvelous way to celebrate my birthday! The title of my poster is “Grass Based Health: The Big Picture.” My take-home point is that a human diet based on animal products – particularly those from ruminant animal – is far more “sustainable” than plant based diets. As we consider this topic, we need to understand that our perception of “wilderness” and “nature” has been as distorted as our understanding of what constitutes a “healthy diet.” I find the following quote by D. F. Lott extremely helpful: “When Lewis and Clark headed west … they were exploring not a wilderness but a vast pasture managed by and for Native Americans” (Lott, 2002) . When Europeans first arrived in North America, they found anything but a primeval landscape.
