    On occasion, when listening to videos taped in other languages that are being delivered as though from an automatic rifle, I slow the playback speed to 75% - thereby facilitating comprehension. I thought of that today while listening to Nick's excited, passionate, and time-aware presentation, and I recommend it for any of us who are actively trying to repair the shreds of our own chemistry, biology, and microbiology backgrounds so that we may follow, relearn, and learn from Nick's presentations, which are made at a "graduate-level kitchen chemistry" level of description and explanation, to enable many of us to hang on. That said, this one is particularly interesting, and I look forward to putting on the hip waders to get through the published article from start to finish ... though I may take a couple of weeks to do so! What a catalyst for curiosity! Thanks, Nick.

    I'm a case study for this. No one could figure out my wheat issues. Went to an allergist because I had trouble breathing when I ate anything even cross contaminated with wheat. Allergy tests stone cold negative. Sent me off to gi. Came back inconclusive for celiac. (6+ weeks out from gluten consumption b/c I couldn't do the challenge.) Genetic test was positive. I've been strictly gluten free for years and on a whim decided to eat a roll at dinner. I was fine. Without going into too much detail, my stress level is significantly lower than when i first received the tentative celiac diagnosis.

      Same - no celiac but wheat ruins me when I am stressed out, work out and sick from a chronic infection (borrelia). Sometimes I can tolerate wheat and other times it makes me feel like I’m in so much pain I’m being cut by a hundred knives, and all my joints feel as if it’s bone on bone osteoarthritis. Never had my arthritis checked but I don’t think it’s actual bone on bone, but after wheat they just hurt. I used to live by a bread factory and I’d smell the bread on the city bus going downtown and Is get instant joint pain in my shoulders and elbows, when I was worn down it’d hurt so much i couldn’t sleep at night. Just from smelling bread 🙈

      As doing a cold tub soak is not easy (at least not for me), My latest hack, get a 30 gallon trash can, put it in the tub. Fill with cold water. Soak a leg. Soak an arm. Soak whatever is aching. You can soak for one minute and get relief. If you have more time, check out sally norton’s mineral bath recipe (2 cups Epsom salt, ½ cup sea salt, ½ cup potassium bicarbonate, ⅓ cup baking soda, 1 tablespoon borax)- enjoy mixed in a nice hot bath. A snorkel makes it
      Even better. You can feel bubbles massaging your scalp etc

      Lol... don't traumatize me. Not a fan of micro... so much SKETCHY! Re the tests you mention, I think they have some utility, especially if tracked over time in an individual to see if various interventions have any effect. That said, they're not that accessible to most people and I'm not sure how "noisy" they are, which could mean a disrupted signal when interpreting the effects of possible interventions... so I wouldn't be too trigger happy about them... but I'm no expert on those tests either.

    Nick, I had to erase 300 words of how keto and your LMHR papers have changed my life, by putting my psoriasis and PsA into remission while providing me tools and studies to help educate my rheumatologist regarding my elevated LDL, to be sure you'd read this part.
    On the topic of the brain-gut-inflammatory triad and the confounding paradox that both vegan and carnivore diets each have positive impacts on health despite being polar opposites, a great common denominator I found in my health journey seems to be a return to a more balanced omega-6:3 ratio.
    Could you explore some of the research done on this specific subject of Omega-3 fatty acids and autoimmune disease and see where the research takes you?
    It would be amazing to learn how your mind synthesizes the information, particularly the large study done in the early 2000s on Omega-3s and inflammation.

      Thanks for the reply, Nick. While I've never found a way to monetize my extraordinary gift, over the years it has become abundantly clear that I have an uncanny ability to get in early on TH-cam channels of people whose pages will eventually grow so large that my comments will become lost in the fray. But for a brief while, when the channel isn't spilling over its own banks-so to speak-these opportunities to briefly interact and communicate with great minds on the bleeding edge of ideas is a true privilege. Hurray to the democratization of knowledge that TH-cam, however imperfect, allows. #CitizenScientists!

    With the bottom up signals from inflammatory insults, doesn't that leave us with the "chicken or egg" conundrom as well as a self perpetuating cycle that could start at either end?

    • @nicknorwitzPhD
      @nicknorwitzPhD  หลายเดือนก่อน +2

      I think, generally, the 'start' is the peripheral insult and the top-down process is modulatory; however, there are negative and positive feedback cycles such that if the cNST loop is dysfunctional (impaired) you can get run-away inflammation because there isn't dampening of the pro-inflammatory response nor compensatory up regulation of the anti-inflammatory response.
