“All of the Blue Zoners consume grain. Of course, those grains aren’t coming in a plastic bag (contained in a box, sealed with glue, under artificial light, etc.), so they’re as coarse and complex as possible. This is also in line with the Weston A. Price dietary recommendations which carry some weight with paleos. Further, as much as I love theory that comes from 50,000 year old skeletons, we have living, breathing data points to study right now.”
