For some strange reason my gut bacteria prefer to eat ice cream and candy instead of cabbage. I keep telling them about these "studies" that they should be eating fiber, but it never helps.
Don’t blame the gut bacteria, blame the parasites😂
Try a fecal transplant, the new neighbors should mame them understand
😂

You have power 😁 of your will, stop giving it away to microscopic or 🪱🪱 parasitic things. Take back your power 🙃💪🏼!
The question isn't:
"Is low gut diversity bad?"
The question is:
"Is diversity good or even necessary?"
It's simply supply and demand. As you stated, if saturated fats go up (which require their own bacterial type), then fiber (and like) intake goes down. If there's no or lesser fiber or plant material, then it stands to reason the bacteria won't be there or are less likely to be there, i.e., "less diversity." If the body doesn't need it, then why would it have it?
That's an easy subscribe for me. Really love the nuance and care you bring to your analysis. Great work.
Context is certainly important. On a high-carbohydrate diet, fiber seems essential. On a strictly carnivorous diet, why would a diverse microbiome be necessary when the diet is not? Isn't the important thing for health the butyrate? And isn't butyrate one of the ketone bodies produced in abundance when one is on a carnivorous diet and the body is in ketosis?
We know of at least one example in the carnivore community of someone who has been a carnivore for 40 years and has not seen a doctor or dentist in over 30 years. We should not make a generalization, but this diet does not seem to be fatal in the short term in any case.
I think it was Dr. Shawn Baker and/or Dr. Paul Saladino who measured the microbiomes of patients on the carnivore diet. As I recall, their microbiomes were as large and diverse as the microbiomes of people on a so-called 'balanced' diet with plenty of fiber.
@@MarmaladeINFP I cannot find a single research study conducted by either of them.
You could just have a mild prebiotic intake and gain the benefits of butyrate without having to limit your diet.
Very interesting! Thank you so much for this video! 🙏💖
I like Huberman Lab podcast, but sometimes it is hard to watch long episodes without losing focus 😊
Your summary and additional information are very helpful! 👍
Thrilled to hear it, Be Strong. Thank you!
I tend to fall asleep during them!
What if we just had probiotic laced condoms
I listen to Huberman while getting my exercise or doing yard work etc. Things that don't require a lot of thinking so that I can actually hear what is being said.
Awesome. ❤😊
I was listening to Dr Ken Berry earlier today and he was saying that we don't need fibre. Personally, I have a high fibre diet and consume small amounts of meat. Thanks for a very informative video Nic.
Hi Nick. I just subscribed to your podcast a couple of weeks ago and already become attached to catch up with all of your previous videos.
I am chemical Engineer and have been involved in nutrition for a long time. I am subscribed to a number of podcasts on this, including Peter Attia, Huberman, Thomas DeLauer… and one that I want you to follow: fitness revolucionario by Marcos Vazquez.
I would like you to talk about “good” saturated fats. I believe that there have been satanized by mixing them in the same bowl as PROCESSED saturated fats.
“Good” saturated fats: chicken skin, pork skin, lard, butter…
“Bad” saturated fats: processed meats: jam, bacon, salami…
We would love your breakdown on these and learn what has been published on this.
Thanks again and keep up your good work.
Regards from Mexico City.
@@Nicksonian thanks for your answer. Incidentally, I am mostly following Mediterranean diet with a bit more of protein (5%-10%) when in HIIT and weightlifting training. My question referred to recommended fats vs non recommended fats in an “expanded Mediterranean diet”. 👏🏻👏🏻👏🏻
great video
I’d looooooove to see microbiome studies on native Italians.
My MIL, for example, cooks 80% vegetables, but after meals are fruits and some nuts and the pasta is loaded with beans or steamed vegetables or a homemade passata (fresh, not canned, tomato sauce. Gift from the gods I tell ya). The amount of pasta is about 70gr (dry weight of course) per person on average. There’s maybe some sausage or thinly sliced chicken breast after the pasta, with salad. Always sourdough bread on the table (ad libitum) and some aged cheeses.
The thing is: everything, and I mean EVERYTHING, is cooked in/drowned in olive oil (and it’s the real deal, we own olive groves, this is our oil. Ditto the almonds on the table). Salad? Oil. Vegetables? Oil. Pasta? Oil.
I’m low oil so I have to put my foot down which is very difficult to explain to her… but I’d love to know what’s going on the their guts.
Even Italian desserts are low sugar, probably half (or less) than what Americans use. It’s glorious 🎉
I would love it. I'm high-oil. I add olive-oil to every cold food I eat, and to hot/cooked I add butter, or sometimes also oil. cold dishes basically bathe in it in my plate. if You weren't low-oil I'd suggest soaking cashew-nuts in olive-oil overnight or even for 2 days-they taste amazing. regards.
How do I get to come to dinner
All I know from experience is that sugar and junk food has ruined my life so going carnivore is way better than eating trash food or high amounts of sugar
Isn’t the fiber argument the definition of healthy user bias? “People who seek more fiber for health reasons are healthier” Compare obese high fiber consumers with fit carnivores and let’s see what happens.
Hi am new 2 your channel!! What is you're opinion on stomach acid?? I have gastritis and am confused.. as one doctor once me on ppi and another wants me on betaine HCl
9:21 That's because there hasn't been a study comparing Carnivore Diet + Fiber supplement vs Carnivore Diet and no Fiber supplement. My understanding is that fiber dampens blood sugar/insulin spikes and so in standard diets consuming carbs and sugar, fiber can offset some of that blood sugar/insulin elevation and thus provides a benefit. But if your diet has no carbs or sugar, that function of fiber is no longer relevant and thus has no positive benefit.
You also don't need whatever particular bacteria that fiber feeds if you're on a carnivore diet. You can process all the food on that diet without it. Furthermore Butyrate is not some unique must have molecule - it get's converted to Ketones according to Dr Paul Mason, which we have plenty of on Carnivore.
Curious to hear any counterarguments to all this. I'm not an expert but this is what I've come to understand in my research.
All good points, Elliot. You're right - there haven't been any studies making those comparisons - I'm looking forward to when there are (it'll be a few years). However, fiber's microbiome effects extend far beyond butyrate - that was just one example of many. So, taking care of the microbiome is essential, regardless of diet - especially since it has wide reaching effects, beyond blood sugar and insulin, as well.
No counterargument to your points specifically, but to the Carnivore diet as a whole: There is still the potential issue of elevated LDL and oxidative stress (which some people claim doesn't matter, but so far I haven't seen concrete, bullet-proof evidence why it wouldn't), the carcinogenic effect of heme-iron and significantly elevated cortisol levels (due to it's role in blood sugar regulation) and TMAO's.
@@Sundara229 The argument for LDL is that there's actually like 4 or 5 subgroups within 'LDL', varying in size. Only the smallest ones cause problems because it makes them unrecognizable to the liver and thus the liver doesn't properly uptake that circulating LDL. But what happens in blood tests of people on the carnivore diet is their total LDL goes up yes, but its almost entirely made up of the larger forms of LDL that are still recognised by the liver, and thus cause no harm. Furthermore, its general poor metabolic health, perhaps seed oils, perhaps alcohol/tobacco, that cause the oxidative stress which transforms LDL into these smaller versions that the liver can't recognise. And those things are not caused by the carnivore diet.

If you scroll down a bit, you'll find this graph:

Small LDL, Large LDL, doesn't appear to matter that much.
@@Elliot_97 Don't forget that most cholesterol is produced by the liver rather than through diet so unless your cholesterol starts exceeding the reference range (ack, mine has), you shouldn't worry too much about the diet part.
I'd be highly sceptical of anything norton says that is not his main area of expertise. Once he made a video about hydrolized collagen saying it does nothing if i remember correctly. But the funny thing was that he instead said one should supplement with hydroxproline instead. Which is completely absurd. For those who don't know: hydroxyproline is part of collagen which would seem like a good choice to supplement with. But, the body cannot use hydroxyproline directly, it has to be broken up to get proline, then used to create procollagen. And only afterwards proline is hydroxylated. On the contrary, hydroxyproline increases the chance for kidney stones. And on a high protein diet, proline is not in short supply anyways( better supplement with glycine...) Long story short, he had no idea what he was talking about and from that time on I was very sceptical about what he says....
Thanks for the commentary.
Thanks for sharing, Reiner. I haven't run across that statement by him, but I could easily have missed it. Like you, I feel collagen supplementation has more in its favor than Dr. Norton seems to think, although, admittedly, the evidence is sparse.
@@PhysionicWhat do you think of it now 😂?
Would love to see a study done with strict carnivores divided into carnivore as usual and the other half carnivore plus prebiotic...maybe using the markers for the Horvath clock, or similar aging clock as the reference - taken before and and at end of study. Carnivore certainly cuts down on the dietary variables.
It would be difficult, maybe impossible, to create a strict carnivore diet without prebiotics. Many substances in animal foods, such as collagen and fat, will feed gut microbes.
Carnivore’s have a great diversity in microbiome. The carnivore diet saved my life
First claim requires citations, because the scientfic consensus is just the opposite. The second is a personal claim that is ancedotal, and doesn't generalize, and not useful since there is no clone of you trying various other diets.
Ha! I should’ve figured you’re from the east coast. Great video as always!
Wish I could remember the details of the research I recently came across while looking into probiotics for my post-surgical child--the gist of it was that, when one takes a course of antibiotics and disrupts one's intestinal biome, there are three conceivable ways of proceeding after treatment has ended. (1) Perform a stool substitute transplant; (2) do nothing; (3) take probiotics. The study found that, if course 1 is followed, re-population of the gut occurs within a few days; if course 2 is followed, the re-population process takes a couple of weeks; if course 3 is followed, re-population is delayed by five months or more. As I recall, the theory advanced to explain this counterintuitive result was that the microorganisms that were introduced in the probiotic package were not native species and in fact competed against the indigenous microorganisms, delaying their proliferation and enabling the rise of rogue strains that, in the ordinary course of affairs, would have been suppressed by the native flora. Lactobacillus, especially, seemed to be a major antagonist of native species and a disruptor of gut equilibrium (and, of course, it's probably the most commonly-consumed probiotic).
so happy i found your channel. Ive been Layne Norton's sub for years now, btw)
I don’t thank you enough for your understanding and explanation of geeky science stuff… but thank you!
I think with the study of the microbiome still in its infancy, we should be careful not to read too much into them. For instance, is more diversity good or bad? Probably depends on what kind of diversity I'd imagine. One of the things that struck me was on bowel movement when Dr Norton was talking about fiber. I started thinking, how do we know what is even optimal? "You go more often and had bulk to stool". Is that good or bad? I think the biggest caveat is that some folks may think that optimal gut health is the end all, be all. Even if it were, we don't know exactly how to achieve it. Then there's the whole psychological aspect of nutrition. Probably the best advice at this time would be to get as far away from the Standard American diet as possible. Minimize processed foods and go for whole foods as much as possible.
yep that's what i got from the Podcast.. he is basically insinuating More diverse gut microbiome means good for you. How can he say that when this is a relatively new field in health and medicine.
it's been proven that a diverse microbiome tends to be more healthy than a less diverse. Now what's true is to know exaclty wht is diverse or not but the fact that diversity is important is known
Where can we access Sinbiotics?
Ok, am I the only one being distracted with a big ass spider like thing on the wall?
What is that oo
No shit, I thought I was just being paranoid lol
I also read that probiotics, even good ones, can crowd out other good ones, not necessarily just the bad ones.
To much of a “GOOD” thing can be a bad thing 👍
Isn't healthy user bias something different than what Norton and Hubberman discussed?
Healthy user bias as they described it is quite easily controlled for by matching participants with similar confounders like exercise, protein content of diet, smaking until only the fiber intake is different between matched groups.
Actual healthy user bias is a selection bias that cannot be controlled for after the participants have been selected for the study. People that are actively trying to be healthier tend to be more likely to sign up for a health study so the study population ends up not being representative of the general much unhealthier population. Like all those people that signed up for that carnivore study for instance.
You could have a point there. I suppose one could interpret it either way; with both being important. The scenario you're describing definitely happens, but often researchers will screen participants pre-study to make sure they meet eligibility criteria for "unhealthy". So, for example, a study on fiber and hypertension would make sure all participants meet the requisite pathology of hypertension. If they do not, they are deemed ineligible to be part of the study. I think there are some populations that this still doesn't address (like race, ethnicity, etc.), but it would address the health aspects of people's lives.
@@Physionic I agree that both interpretations of health user bias are important to combat and these are thankfully properly combatted in the majority of studies. Yet, my interpretation of healthy user bias is not limited to epidemiology and is combatted in the participant selection phase of the research process in contrast to the data analysis phase.
Because of this the interpretation of this bias by Norton and Huberman might be better described by 'multicollinearity' as multicollinearity means several independent variables in a model are correlated like high fiber intake and exercise, processed food intake.
I will admit I am nit-picking, but seeing that many people think epidemiological studies are useless no matter how well they are done (and their participants are selected with incredible care) because "healthy user bias cannot be controlled for in such studies" I hope you understand my nit-picking.
There are some studies that use multiple models to produce the final measurements, and one i read recently used 4 or 5 different models and accounted for factors like you mentioned in one of them.
I love this channel. Full stop
Thank you!
I stopped eating sugar n crap. Tried to be in a caloric deficit. Ate alot of greens. After about a month my intestinals are not happy. Mucus in stool, bloating... Anybody with similar experience?
Really appreciate your unbiased feedback in your videos. One thing I am very conflicted on though is Paul Saladino and his stance against vegetables. It’s very compelling. Do you have any particular thoughts on his nose to tail carnivore diet with fruit and honey?
It seems through his bloodwork reviews every year it is optimal.
I have done absolutely zero research into the vegetable, hormesis, toxicity debate, but my initial instinct is to say his stance seems like nonsense to me. This seems like yet another person getting caught up in mechanisms without accounting for the vast ocean of outcome data that strongly screams eating vegetables and fruits is a benefit to health.
It was my impression that his blood work had quite elevated in measures of LDL, ApoB, though, so I don't think I'd agree with the statement that his blood work is optimal.
Thanks, J!
@@Physionic thanks for the response !
Here's something to factor in to your thinking. The Maasai people eat meat, milk and blood. They walk 19km a day or more. They die at about 45 years. You can look up that abysmal life span and that should help you decide if you want to give up veggies and fruit. Oh yes, also the Inuit of Canada and Greenland, eat a high meat diet because they hunt and they die on average, ten years sooner than us southerners of Canada do. And if you want, I can give you the link to the Canadian governments page that talks about Inuit mortality. @@jdeprimo5030
Saladino is vitamin a toxic. His liver is full up with retinyl esters and he is not healthy
Ah yes, the same grifter who said that he didn't know that his partner, the liver king, was taking steroids...
They are all a bunch of conmen/liars, telling people what they want to hear.
The actual risk of red meat is minimal, the majority of people deciding what gets into recent studies were 7th day Adventists who excluded all the positive relation studies.

@@mikeyblueeyes8449 Scientific research undergoes rigorous peer review and scrutiny, regardless of researchers' affiliations.

Since I stopped eating fiber my gut health is so much better, I go to the toilet every single day without any effort, literally zero. I eat animal proteins with white bread/ white pasta/ and Jasmine rice as a source of carbs, I do IF and I eat a lot of extra virgin olive oil. I also take different supplements like S.Boulardi, digestive enzymes, NAC ect...
But consuming vegetables and fruit was a game changer for me, don't know why
Are there any studies or could you look into carnivore diet being either beneficial or detrimental for men with prostate cancer? Whether it be early stage or late stage, or high or low Gleason score?
None.
@@Physionic None, as in no studies in either direction?
Good.
Againk, a good critique of the Huberman video. Good job!
Did I miss something regarding the success the Inuits have had with their diet? Dr. Lustig, since you mentioned him, has claimed even until recently,that their diet is not unsound from a medical perspective, regardless of the lack of fiber.
Also lack of other nutrients which makes for painful osteoporosis, but so far they have been surviving on that diet for millennia.
@@GiveMeCoffee I appreciate you sharing that. Good info. What percentage of their population develops osteoporosis and compared to whom and under which diets insofar the group or groups under comparison?
@@J_The_Colossal_Squid I saw a comparison from the National Institute of Public Health in Quebec in 2004 between women from several ethnicities and a group of Inuit women, the frequency of osteoporosis was 7 per cent compared to 19 per cent. The are also studies that point to higher cardiovascular risk (lower risk of diabetes) and more prevalence of gout (as with Taiwanese aboriginals and Maori). As for diet I understand Inuit consume mostly marine and terrestrial mammals, and sea birds and fish, but what would be relevant is the role of salt (higher levels of uric acid when in a carnivore diet) and calcium intake, lack of vitD during the darker months (which helps to absorb calcium in the bones) and the pollutants present in the meat they consume.
@@GiveMeCoffee Thank you. That is a huge difference. Sad they couldn't include males in their study too, - but also one that makes sense, given the relative lack of D. -- I,ve got a friend who gets Gout. Nasty condition. Of course we don't let the exceptions drive our management at the mean. Maybe they've (i.e., the males) have been studied elsewhere? Anyway, my area of study is _criminology_ so I don't really have any dogs in this one, past personal curiosity and interest. Thanks again
@@J_The_Colossal_Squid I think in females bone density loss is higher due to pregnancies, and they found some hundreds of years old mummies from female Inuits with severe bone density loss for how young they were at the time of death, maybe that is what made them focus on the Inuit women for those studies. Hehe, I'm not an expert in this either, just been on different diet protocols due to fibromyalgia, pcos and other issues, lots of curiosity too :) you are welcome!
I don't know anything except.
People on the carnivore diet are getting health and people eating according to the W H O are fat and sick.
That's all I need to understand.
Exactly, this needs to be pinned

Nick, can our bodies ferment fiber? If not, how can we utilize it. In the numerous studies on fiber, are the subject going from a SAD to eating more fiber or carnivore to fiber?
Nope. the bugs in our gut can digest fiber. In their turn these bugs produce short chain fatty acids, which in their turn are healthy for us. This is why you should eat plants.
@@k.h.6991lol no. Everyone's health improves when they move from plant-based to carnivore.
No, Humans can't ferment fiber like herbivores with multi chambered stomachs or omnivores with a cecum, Our digestive tract moves too quickly to get any benefit from fiber. 😉
@@RiordanLadyGaga did you even watch the video. They also never said vegan > carnivore. She said ommivore > carnivore.
@@classypotato9255Yeah this. I think eating adequate protein and whatever fat comes with it, plus some less processed and less glycemic carbs are good for the body. Essential amino acids, essential fatty acids, then fiber and carbohydrate. Strength/HIT, HIIT, and do low heart rate aerobic activity and you'll be really damn healthy for a long time.
Saturated fat, may not be good for the Microbiome?! You lost me right there. The problem with this video and many other videos like it, is that it views diet through the lens of the typical western diet. Additionally, every scientist and every study done on red meat, and or fiber is done by someone not attempting to properly follow a carnivore diet. You can look quite deeply into all these supposed health benefits of pre-biotics and probiotics and the positive and negative affects of fatty acids. Or you can just eat a proper human diet of mainly meat and watched your health and gut biome flourish.
If your position was accurate - then wouldn't you expect to see positive health outcomes associated with upper intakes of red meat vs lower intakes amongst westerners?... If you agree that the standard western diet is unhealthy - then replacing part of that diet with red meat would presumably improve health, no?...
So why, then, do we consistently see the opposite!?... Substitution analysis show that replacing unprocessed red meat with almost any food leads to positive health outcomes...
@@ItsJordaninnit we actually never see the opposite. Every study that supposedly shows red meats unhealthiness is marred by counting diets that consist of red meat and carbs. The internet is chock full of carnivore pages and Facebook groups that show the amount of people who thrive eating this way and the amount of people who’ve reversed thought to be incurable cancers and even reversed arterial plaque.
My position is quite accurate.
@@sunnyguitardude But again... the more meat you consume, the LESS carbs are being eaten. So unless your position is that Red Meat is healthy IF and ONLY if it's consumed within the context of a ZERO carb diet... then you'd have to reconcile the substitution analysis which show replacing red meat with plant foods, fish, yoghurt, chicken etc - results in positive health outcomes...
I'm sorry but unverified anecdotes from carnivores on facebook is not evidence.
The Internet is also flooded by stories of people following low fat vegan diets... don't just go with anecdotes on the Internet
@@sunnyguitardude
I clicked because of the picture of you as “ a dude “. Lol😂😂😂😂😂
Thank you for this thoughtful analysis.
Assume for a minute that humans evolved primarily from eating meat often with little or no plant material except in extreme survival situations.
Why would we give any credence to studies where the pool of subjects are plant stuffed? Of course they will have a more diverse microbiome, they are trying to digest non-optimal material. Of course they will benefit from fiber, they have a challenging and unnatural digestive task. Also, things that are normally healthy to the ancestral meat eater will appear problematic in this artificial situation. For example, red meat, saturated fat and salt.
Would butyrate from butter also benefit the gut or is it absorbed too early in the small intestine to have an effect?
You always have great questions, Mario.
I don’t know the answer for certain, but I doubt it would help the gut, specifically, since butyrate is the product in the microbiome reaction, not the reactant.
And, to your point, it may be absorbed earlier in the duodenum.
Even if it was absorbed, the negative effects of the saturated fat in butter would most certainly outweigh any potential benefit from butyrate…
@@AislingDonohoe would you please elaborate on what the negative effects of saturated fat are? Nic has many videos about SF transient increasing insulin resistance but I think that is not an issue if you don't eat high GI foods along with the SF
@@Mario-forall Saturated fat independently increases CVD risk, that's pretty well established. I think primarily through increasing LDL cholesterol.
@@Mario-forall Sigma Nutrition have some excellent articles and podcasts on these topics.
to the fiber argument, humans have a tube, where does fiber ferment? You want fiber rotting in your digestive tract? but why?
In the large intestine. The tube is made of cells and contains cells.
Thanks for a fabulous summary and insights into the effects of saturated fats vs mono vs polyunsaturated fats on microbiome diversity! Both walnuts and almonds have a good balance of fiber, mono/polyunsaturated fats and very low sat fats as well as plant protein, and in larger studies have shown to increase longevity by a few yrs (not just healthspan). Pistachios also are lower calorie with a good healthy fat balance and has been shown to reduce oxidative damage to DNA and increases the gene expression of some telomere-associated maintenance genes. So long as you are not eating too much each day, you can reap all the benefits in a handful of certain mixed nuts a day.
Always bringing some extra info, Talia. :)

@@DeyBwah hardly any and no effect on regular people.
Check out the biome of hunter gatherers, such as the Hadzas and Yanamamo, most diverse on the planet.

There's not enough data to draw strong conclusions as he does. Gut microbiome research is in its infancy. I'd not make any meaninful diety choices based on this.
There is actually a pretty good amount of human trials showing different effects of prebiotic intervention. You can also search terms for oligofructose, fructooligosaccharides, galactooligosaccharides, beta-glucans, among others.
It’s hard to take Layne seriously. He doesn’t know the difference between diverticulosis and diverticulitis, and he’s not familiar with any of the research from Dr. Justin Sonnenberg. so, when he discusses gut Health, I take it with a grain of salt since he has no idea what he’s talking about, and it’s outside of his field of study. just like when he decides to comment on cancer and pretend that he’s an oncologist, he’s so far off base it’s actually kind of frightening that people look to him as an expert.
Ummm what 😅😅
@@Ratchetti he studied protein and leucine. You can go read his dissertation. He thinks that oncology experts are idiots about cancer, and he thinks that Sonnenberg doesn’t know anything about gut health. Just because you have a PhD doesn’t mean that you’re an expert on every single field. In fact, having a PhD pretty much requires that you focus on one single field of study at the expense of everything else. And when he debated Paul Saladino, Layne had no idea that diverticulosis and diverticulitis were different conditions. You can’t act like you’re an expert on gut health and gastroenterology, and then not know the difference between diverticulitis and diverticulosis.
why are people on the carnivore diet not dropping dead or getting a lot of health issues? or are they lying about their health.

@@arihaviv8510 could be. if i look here on youtube alone. some do great sofar and other wreck their health in a few years on the carnivore. also the answers here above. one gets his gout reversed on carnivore and the other gets gout.
Bacteria in the lab is mutating constantly. So I would have thought that with the right diet, the gut Bacteria would simply evolve to match
All this fiber talk doesn't make a lot of sense to me. I'm sure that people on bad diets benefit from eating more fiber rich foods. But that is association, not causation. Fiber rich food are not processed foods, so that's a big confounder.
But before getting into details I always first like to look at some high level properties. Here are some high level properties of vegan vs carnivore diet which means high fiber vs low (zero) fiber:
Vegans get sick more often than average.
Carnivores get sick less often than average.
This always needs to be taken into account. No matter what aspect you study, you always need to be aware of those aspects.
High fiber, low saturated fat,... means you get sick more often? While low fiber, high saturated fat,.. means you get sick less often. Whatever you say about fiber and saturated fat, it can't be the case that getting sick more often is the healthier way to eat.
Psyllium husks 👌
I was literally just reading an article on psyllium husk and then saw your comment, James. Too cool!
@@Physionic - 😉👌
they never get granular enough in my opinion. fiber is great but from what? fiber from vegetables? what king?
from what i found the problem is the pesticides, fungicides and antibiotics like glyphosate that screws up the gut by disrupting the microbiome drastically that eventually lead people to have sensitivity to fiber.
the quality of the products consumed is of utter importance and lots of studies dont even differentiate that.
100% organic vegetables and probiotic foods and drinks will be the only logical approach to be a profilactic or even recovery after antibiotics which personally have been affected with 90+ days of penecillin from a tick bite. After thaty instance my digestion has been destroyed. thats my anecdotal truth.
meat quality is of utter importance.
The word "Synbiotics" sounds a lot like "symbiotics" and, at first, that's what I had heard. And when I hear talk about "take" symbiots to live in my colon, what I really think is : OK, maybe this might be goid for me, but, if I'm gonna put symbiots in my arse, I want to really inow them first. Like, I want to meet their parents, see their resume and their record ...🤔
The full conversation might have more detail, but Dr. Norton doesn't distinguish between types of fiber. That is very discrediting.
Nic-biotic 😁
I might have a good case for you to review. A few days ago a "documentary" started to pop up in my YT feed named 'Burzynsky: A cancer cure cover-up'.
I have not seen it yet, but the red flag title and description makes my bs-senses tingle. You might know more about the subject and be able to distinguish fact from fiction.
Btw: I forgot to tell you: Good job on this video. I learned a lot!😁
I'd love to cover it, but it's an hour and a half and seems like it would attract battalions of people that would just bash me for making any corrections. I would cover it if I felt it could be constructive, but I'm also backlogged with about a thousand other topics I'm trying to get content out for everyone. Appreciate the suggestion, though - as always.
@@Physionic Your response is understandable. I also don't want to watch a (likely) conspiracy video like this one of 1.5hours long.
However, maybe you will find the time to make an unbiased short video to explain the biochemistry of "antineoplastons" without mentioning Burzynsky too much. That way it might help drive some more attention to your channel from people that are searching for some clarity on the subject.
Anyway, good luck on the backlog.🙂
I’ve watched it and it was extremely informative.. for my brain anyway.. let’s face it a lot of information is kept from us .. maybe watch it in bouts Nicolas 🤔..
I couldn't wait to watch this.. I really enjoy Laynes videos and have learned a lot from him. He has a way about him that makes his videos entertaining as well as informative... Huberman, not so much. I really don't trust his info as he tends to really reach and cherry pick the studies. It would be awesome if you and Layne could get together and do a video.
I've tended to really like Dr. Norton's interpretations of the data. I've been a bit less convinced of Dr. Huberman, but I still feel he's doing well enough. Like you, I think he stretches interpretations, at times.
Would love to do a video with Dr. Norton.
I don't know if Huberman understands methods or stats. But he's a good communicator
Ever since your dad’s post I can’t get past your pet cockroach on your wall…😂
:)
Short chain fatty Acid in Ghee and Goat cheese of course if the source coming from a good clean source
Didn't he just say saturated fat decreases gut microbiome? Why would you assume the net effect would be positive from ghee if there is no fiber for the biome to feed on and it is 50 percent saturated fat? Also the net effect on longevity from poor lipids? Fiber seems like a much safer option unless you have outcome data for your position.
@@okaynope5197there's is no proof that saturated fat causes heart disease. If that were true how would our hunter gatherer ancestors survive and thrive for 100,000 years.
@@okaynope5197I don't need a diverse gut biome. I need very acidic stomach juices to digest my food.
@@veniqerReally acidic stomachs leads to ulcers and stomach cancer so have fun with that
Edit: Also did you watch the video? A diverse microbiome has several health benefits beyond just digesting food
So what’s the big deal about getting buterade from fibre ? I get it from butter everyday.
Getting SCFAs in the gut creates solid barrier in the large intestine. Inside your gut microbiota is a large amounts of bacteroides, which are gram-negative bacteria.
On the shells of these microbes are lipopolysaccharides or LPS. These LPS molecules are harmless if they stay inside your intestine, but if they leak out into your bloodstream, they hook up with LDL cholesterol start a chain reaction of a lot of bad stuff that's going to hit you down the road.
The butyrate prevents this.
Soo much so called scientific evidence out there that can prove and yet disprove every hypothesis … Do what works for you, listen to your body it will let you know when change is needed… physionic your 🔥 I’ve noticed your physiological changes 😻stay strong luv your videos, keep them coming and us informed 😮
So many scientific studies that are bought and paid for!! I cut out fibre and vegetables and my 5 year gut problems went away 🤔
He is a carnivore..secretly😂
I found Huberman's podcast refreshing in its infancy, but got an undeniable hunch that compelled me to unsubscribe when during one of his episodes he started talking about the characteristics of victims in muggings.
What exactly is to be gleamed from observations like these? Who gets to benefit from the findings? Who is the research for; narcissists and psychopaths?
On the contrary it would be prudent to expose the psychology of perpetrators: perpetrators attack the disempowered. This research exposes the wrong party.
I have since unsubscribed and am not too surprised to learn that he does not in fact reject the carnivore diet. He shows poor judgement.
Just a couple of things I love Layne, find him to be one of the most reputable You Tubers , and I subscribe to his channel. Having said that if you search Simon Hill’s podcasts where he interviews some of the top gut microbiome researchers in the field, there seem to be differences in their views. One side says your gut microbiome bacterial makeup is pretty much established at birth and what diarupts their existance is exposure to SAD diet consisting of emulsifiers and other potentially additives and chemicals that kill off the bacteria. This also includes antibiotic use. So if you attempt to repopulate your gut with a cocktail of peobiotics and probiotics , it may not result in resolving the issue as your original strain of bacteria will always atrempt to repopulate and take priority. The other side says not totally true and consuming more prebiotic and probiotic foods like kefir, kombucha, kimchi, and sauerkraut can and will change your gut microbial makeup for the better and significantly improve your gut microbial makeup. There is also some debate as to why people have issues with fibre and probiotics or things getting worse. It is like the what came first tge chicken or the egg debate. Some claim that absence of fibre can cause some microbes in your gut to cannibalize your gut mucosal layer which can lead to leaky gut. Others say if you don’t have enough of a gut microbial makeup and you consume more fibre to start with, all that you will end up doing is p*oing the limited gut microbial bacteria as the fibre will act as a sponge. This long term can do more harm than good. Bro,now you understand why people can become so mistrustful and suspicious of Science and Research when even top experts in the field cannot agree among themselves and disseminate conflicting if not contradictory messages.
Interesting. The "diverse" microbiome I get when I eat a lot of fiber always seems to mess up my skin, digestion and sleep quality. I think Ill stick to have no microbiome diversity.
I’m glad you agreed with them, for a sec I thought you were going to debunk them. Layne and Andrew Huberman are legends
Nah, they do great work.
It's refreshing to hear this. I get a lot of carnivore diet advocates in my feed because I click on them for aome reason and end up banging my head on the wall at the fallacious reasoning and lack of knowledge of the side of fiber, legumes, and vegetables. Thanks for helping to dispel myths.
