I must respond to your comment as it is so spot-on. I am starting to think the core paleo conceit of our health being ruined by eating particular things, and we can all be fixed by avoiding them, is simply wrong. Dangerously, misleadingly, wrong.
I've long ago tossed the idea that a particular macro ratio is poison, and am now starting to think that the EM2 (or EEA) is defined less by novel NADS as particular substances, and more by the gut microbiome and environmental pseudocommensals and their critical effects on our health.
I believe loss of tolerance for eating just about anything (except obvious NADS like excess LA and huge amounts of fructose) is a sign of immune dysregulation in MOST cases. It definitely is a sign of immune dysregulation to have an allergy to beef, or shellfish, or rice (very common in Japan). I disagree with Dr. Ayer's on that point. Even IBS has been recently shown to be characterized by abnormal mast cell populations in the gut- the same cells mediating airway and skin allergies.
Take the case of Wolf. Robb Wolf was not poisoned by wheat and saved by paleo. He was rather a victim of a particular disease of immune dysregulation- celiac disease - which was and is ameliorated BUT NOT CURED by a wheat free paleo diet. He must stay off gluten to stay in remission. He is not "cured". If he were he could eat wheat with impunity like I can (Yes, my tests for celiac were negative).
In the same way, someone with Crohn's disease or AS is not being poisoned by starch feeding particular bacteria in the gut, they are victims of an abnormal immune response to gut bacteria macromolecules that we are supposed to be able to - are actually evolved to - tolerate. The GAPS diet or similar, if it works for IBD, is palliative and not curative. The idea that starch or even gluten are per se NADS is wrong.
As you have discovered, one may eat any of a variety of PERFECT paleo diets and still not really be emulating the EM2, and therefore may still be or become seriously sick.
In your own case, you've palliated your Crohn's disease with diet, but still have a haywire immune system, which now has given you the disease of Lupus.
Unfortunately, it is highly unlikely that any paleo diet or guru with do anything for your Lupus, because what particular foods you eat is not the most important part of the EM2 that you are missing.
If you want to, you can email me off blog.
The auto-immune paleo diet didn't do me much good, except for the first month or 2. Since adopting some of Ray Peat's ideas, who focuses more on eating things than not eating things, I'm a lot better (I do have a long history of hypo-thyroid-like symptoms).
His fructose hate bothers me a lot though.
What are your thoughts on this? Is gluten the new safe starch? Does food avoidance equal stupidity?
