Resistant Starch: 4-Letter Word? Nope. Goal: Create Mashed Potatoes A Diabetic Can Eat Every Day

The interest over those posts has been rather enthusiastic, in spite of my concern over: "Oh, what new miracle is Richard-The-Traffic-Whore on about now?" And it's a legitimate criticism in my book, especially if not completely familiar with the history around here.

As I wrapped up that post yesterday:

My next post will be about the tons and tons of research into Resistant Starch in the last 30 years that's not financed by someone with a financial interest. I've collected a veritable shitload, thanks to the help of commenter, retired Air Force, Arctic Circle living, lay digger upper of research papers: "tatertot." Following that will be a post cataloging my own results over the last couple of months, as well as that of many others including my T2D mom.

Both tatertot & I firmly agree that resistant starch is an enormous blind spot in paleo. Go look at what they find in human shit fossils (coprolites). Hint: not a full rack of ribs and a side of salad dressed in olive oil and balsamic.

Oh, "tatertot," is also just Tim. In addition to the other things I cited, he's a hunter, trapper, fisherman, weekend farmer and full-time electrical systems supervisor in a local hospital up there a short hop from the North Pole. He does not work for a starch company. Tim and I've been collaborating for months on this, but he's the one who dug up the research and connected dots. I got people interested and collected a shitload of human guinea pigs so that everyone can see soon enough if we've just been taking the piss.

Before I begin, here's a pretty good primer on the importance of gut bacteria in Mother Jones: Are Happy Gut Bacteria Key to Weight Loss? That briefly mentions resistant starch near the end—still a blind spot, in my view, but a great primer. Then there's this, from Primalmeded: Resistant starch: the missing ingredient? This strikes as a bit cherry picking in reverse, to me, on grounds that the research cited is mostly, or all, from a producer of "Hi-Maze," an engineered corn starch product. A far more balanced piece is by Norm Robillard, PhD microbiologist and former researcher, of Digestive Health Institute: Resistant Starch – Friend or Foe? (Interesting how all three citations are questions, eh?) Anyway, Norm's chief concern appears to me to be the potential for RS to aggravate Small Intestine Bacterial Overgrowth (SIBO), but in his learned defense, I suspect that's not an indictment of RS per se, but more of having vast numbers of people who've "sawed of the branch they were standing on" by a lifetime of consuming the SAD—which I'm confident he would agree contributes to SIBO. In my next post on the various anecdotes of self-experimentation I've collected, I'll speculate as to why I think it might not be too much of a concern for many.
