[14:00](https://youtu.be/ZemkG6Vj7hc?si=IFPCyFczzwPP3cgk&t=840) It would have been nice to highlight why causal inferences from Gundry's cited data would be dubious. He cites data is cross-sectional in natural, which lacks any evaluation of temporality. I also lacks individual-level follow-up and makes it susceptible to ecological fallacies. [15:00](https://youtu.be/ZemkG6Vj7hc?si=0wC9799emR0MnxQt&t=900) You seem to suggest that blue zones could give us an indication of the compatibility between different dietary patterns and longevity, but I don't even think that they tell us that much because of the cross-sectional nature and the susceptibility to bias and confounding. People could generally be eating a particular diet in the region and have markedly improved average longevity, but without individual-level measurements, it could be the case that the ones living the longest are the ones who are, on average, deviating from local dietary norms. [15:20](https://youtu.be/ZemkG6Vj7hc?si=BKmIoCzyLgEQ08LG&t=920) Okay, yeah, you alluded to it. 👍 [16:00](https://youtu.be/ZemkG6Vj7hc?si=hNH_RABHWBKklNDy&t=960) Something to bring up here would be the fact that the prospective cohort studies that underpin our understanding of the relationship between smoking and poor health outcomes is routinely adjusted for both vitamin C and diet quality. So, the literature tends to produce results that are not expected on Gundry's hypothesis. [18:30](https://youtu.be/ZemkG6Vj7hc?si=hRHT6ML5s8tB7d4j&t=1110) Gundry literally confuses nicotine and vitamin B3, haha. Bruh. [19:30](https://youtu.be/ZemkG6Vj7hc?si=HtBbugN4FXlB75wf&t=1170) It would have been nice to dunk on him about not understanding the difference between nicotine and B3. Even if you had to pull out your phone and look up the molecular structures to show they're entirely different things and have no relation to one another, haha. Those dunk points would be 100% worth it. Then force a concession that nicotine and B3 are not related. That would have been beautiful. [21:30](https://youtu.be/ZemkG6Vj7hc?si=Bs2Cfcz9CTIFaRbU&t=1290) This was a really well articulated accounting of the literature on LPa and its relationship to outcomes. It shouldn't be taken for granted that anything that lowers LPa will be favourable as an intervention (such as liver disease). [24:10](https://youtu.be/ZemkG6Vj7hc?si=3nIZY_p-PHpp9Fv9&t=1450) The guidelines do not recommend to lower ApoB to lower oxPL levels, lol. You should have pressed him to substantiate this claim. OxPL and oxLDL don't have any clinical utility that I'm aware of, and the literature investigating them as independent risk factors hasn't been very fruitful for the hypothesis that they drive risk over and above ApoB. I dunno where he's getting this stuff, but he should have been pressed hard on this point. Beyond appealing to the guidelines, it would be helpful to explain why lowering ApoB is the gold standard recommendation for primary and secondary CVD prevention. It's merely because no other markers tend to survive adjustment and/or control for ApoB when analyzed, and the ones that do already have different treatment modality (such as beta blockers for hypertension, GLP1 for obesity, etc). We don't have a good justification for for making oxPL or oxLDL a target for therapy. [25:05](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=1505) You provided a question-begging argument here. An argument that assumes the conclusion in its premises; investigations into oxPL won't change guidelines because management is going to be lowering ApoB. This could be avoided by merely elaborating on why oxPL is not currently a target for therapy. [26:30](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=1590) Mike asks a very good question, and Gundry dodges and proceeds to ramble. It would have been appropriate to cut him off and directly ask him how he's deriving generalizable conclusions based on his mechanistic reasoning. If his response is "I see patients tho", simply direct him to a picture of the evidence hierarchy and ask him why recommendations should be guided by the lowest possible rung. [27:30](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=1650) Gundry dodged another direct question about oxPL and heart attacks. When pressed again, he started rambling about beta blockers. It would have been good to press him for an answer. The intention of this discussion is to confront Gundry on his views and see how robust his views are to scrutiny. He should be providing answers to every question he's asked, but he doesn't. Redirecting him back onto a linear path is crucial. Sophists will try to side-step you. You have to keep them linear and force answers when necessary. [29:35](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=1775) Good good, you explained by ApoB trumps his pet biomarkers in terms of epistemic virtuousness. It's good that you did, but it should have been done at 24:10. 👍 [31:30](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=1890) This motherfucker starts yacking about leaky gut. It would have been nice to just stop him and ask him for the ICD-10/11 code for leaky gut. When he can't produce one, ask him why he's trying to diagnose and treat a disease that doesn't seem to exist. [35:50](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2150) Gundry criticizes your epistemology as "incomplete". You ask him "how so?". But, it would have been better to ask him what he means by "incomplete", because it'll probably cash out into something trivial that you might not even disagree with, but won't really succeed as a criticism against you. For example, if by incomplete he actually means you're not in possession of all of the facts or whatever, that's a criticism that will be true of all scientific and epistemic modalities. So who cares? Scrutinizing your opponents semantics when they say something bizarre or vague like "incomplete" can be a great way to demonstrate to the audience that they're out to lunch and/or gibberating. Semantic analysis is super important. [36:25](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2185) Again with this leaky gut shit. He needs to give the ICD-10/11 code or GTFO. [37:00](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2220) LMAO. You both asked him for a symmetry breaker between his anecdotes and other doctors anecdotes, despite mutually incompatible recommendations and great patient results, and he basically responds with a non-answer; "I treat their failures and they treat my failures". He should have been dicked into the dirt here. He should have been pressed mercilessly for that symmetry breaker; what justifies sooner believing Gundry's anecdotes over some other quacks's anecdotes. [37:50](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2270) Would have been nice to point out that the Lyon Diet Heart Study also replaced meat with bread, lol. That would have ground his gears. It's a good study, but I'd be less confident in the results because the confidence intervals for RR were a barn door, unfortunately. The results are compatible with virtually abolishing CVD and also compatible with barely making a dent. It's really hard to draw firm conclusions from it, despite the seemingly impressive results. It think you make a good point, though. Regardless of what I just said there, the results aren't expected on Gundry's hypothesis. [40:00](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2400) Wtf is this clown talking about? Antioxidants weren't included in the model for the final analysis in the LDHS. This mf is huffing whippits. He's just fucking hallucinating before our eyes. ![[Pasted image 20240711165008.png]] [42:00](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2520) He's back on this leaky gut shit again. He needs to be pressed. ICD-10/11 codes, my dude. [48:00](https://youtu.be/ZemkG6Vj7hc?si=hv74MzmRybpA2C7u&t=2880) It's clear the discussion has gone completely off the rails because both Mike and yourself are allowing him to steer you down rabbitholes. It's probably no longer clear to the audience what the topic of discussion even is anymore. The convo desperately needs to be steered toward a path of linearity. He's made a number of wacky claims, but ultimately he's presumably there to defend his position that lectins causes leaky gut which leads to auto-immunity, which leads to all disease. His position can be formalized as such:
