Here's the reference: Prepare for the “Resistant Starch” Assimilation; Resistance is Futile. It started off slow, rather as I'd expected, because: STARCH! (Fingers raised across face in the sign of a cross.) But, comments began picking up and even though the post is quite a ways down in the scroll, it's what's getting the most play currently. And now, those who began their own experiments are beginning to report in.
I'm tickled at the authoritarian poo-pooing here & there. Not fooled for a second, though. Disappointed? Maybe a smidgen, but I'm counting on the last laugh. I would have thought that the sciency folks out there would have at least taken up some well-placed clues before proclaiming the issue of Resistant Starch to be so much hype.
...I see things like "I have boatloads of studies on it." I call absolute lying bullshit. They do not—at least not that they've carefully read (I can't dismiss out-of-hand what I've read carefully on the matter, and I live by my own standards). I also suspect you are being lied to by them...just because it's "obvious," dontcha see? Nothing to see here. It's "starch," and starch is a "4-letter word." Yea, yea; and bla, bla. "There's no essential carbohydrate" (true, but bullshit, because every human animal on Earth eats starch and always has). "Grains simply aren't necessary" (true, and thanks for demonstrating how you just lied...because this is not about grains—also a very poor source of RS). ...Plenty more lazy dismissive bullshit where that came from, but you get the idea.
In the end, trust is the only thing that really matters—not your popularity, not your credentials, and not anything else. The root of the problem is laziness. I grant that allure. Once people start seeking you out, asking advice, commenting on your blog, it get's easy to just play authority. Of course, there are certain things in paleo we can rightly consider settled: avoid processed foods, refined sugars & grass seed oils, grains generally. You do have to draw lines, or literally everything is an endless open question forevermore, and nothing gets done because nobody can get off square one.
