Many are already convinced that the original take on the Paleo Diet got it wrong on starchy tubers (and starch in general), legumes, honey, and perhaps a few other things...like the idea one is best suited to a high fat, high protein, and low carb, or even ketogenic, diet.

There's many posts here on all of that stuff and in terms of potatoes, going back to 2009 even. Curiosity gets the best of me and I'm never comfortable or satisfied with pat, just-so answers to anything.

Moreover, way back, the science of the gut microbiome was a gaping hole in terms of integration into the diet. That's perhaps the most understandable, since it's only in the last few years that the science has skyrocketed. There is no shame in ignorance, only in refusing to correct it when new facts present themselves.

Before I delve into why I think paleo may have gotten it wrong on grains, let me post an email I got yesterday from a long-time reader and commenter, Steven.
