The link to the Paleolithic diet made me think that one strategy against increasing addition is to normalize for evolutionary time. Still requires a lot of learned, subjective insight. But basically, anything that has proved itself via evolution is more sturdy and is worth congregating around (these include immediate things that affect the body, but also the evolution of societies, etc.). Bravo on another great essay…
Even its concept is flawed. Some things it discards, such as wheat are barely changed from what our ancestors were eating long before agriculture or town settlements. One reason wheat was adopted so widely so early is that it didn't need to change much to be domesticated (see Guns Germs and Steel). Strawberries on the other hand, weren't domesticated until medieval times, and the same is true of many nuts, most notably almonds. Cattle has also undergone a far larger genetic transformation than many of our primary grain crops. Most damning to the idea of a paleo diet is that we have, too.
Human evolution has clearly accelerated with population growth. According to some anthropologists, modern humans differ more from those 5,000 years ago than those humans differed from Neanderthal.

In short, the paleo diet rests on flawed assumptions about evolution, the history of agriculture and ignores the main body of nutritional research and is rightfully considered a fad diet by the NHS and similar organizations.
Edit: It's also horribly unsustainable. A hummer-driving vegan doesn't have anywhere near the ecological footprint of a bicycle-riding "paleo" dieter.
