Gil Carvalho, MD PHD on: Red Meat

#NutritionMadeSimple #GilCarvalho We're all confused about Red Meat. Here's Why. 28,588 viewsMar 28, 2022 1.9K DISLIKE SHARE DOWNLOAD CLIP SAVE Nutrition Made Simple! 101K subscribers Why is red meat so controversial? Heart disease or heart-healthy? Grass-fed or grain-fed? Established or undetermined? Beef, lamb, bacon or ham? A look at the scientific evidence on the health impact of red meat. forget whether you love or hate red meat. what is the health effect of eating red meat on cvd higher consumption of red meat associated with risk of CHD increased risk of death due to different causes incl. HD associated with red meat intake whats our level of certainty regarding effect of red meat on CVD? Very low. red meat includes bacon, salami, beef jerky, etc as well as steaks. maybe processed red meat is a problem but steaks are fine higher intake of total red meat or red meat excluding processed meat, both were significantly associated with risk of CHD. Both processed and unprocessed red meat associated with mortality incl. HD higher consumption of unprocessed red meat associated with 9% higher risk of ischemic heart disease per 50g eaten daily, about a quarter of a 8oz steak People who eat more red meat also tend to exercise less, smoke more, drink more alcohol, etc. maybe those factors are the real problem and red meat is an innocent bystander? associations with red meat were stronger after other risk factors removed from the equation. mortality associated with red meat was stronger in non/former smokers, in people with normal BMI, and non/mild alcohol drinkers do ultraprocessed food and animal foods incl. red meat have independent health effects? red meat associated with risk even after ultraprocessed food taken out of the equation. association btw red meat and disease can’t be simply pinned on junk food if red meat is an innocent bystander we might expect red meat to be less harmful in the context of a healthy diet. But association between unprocessed red meat and CVD was stronger in participants who consumed a higher-quality diet red meat without junk food showed if anything stronger associations increased risks associated with red meat may be partly accounted for by heme iron and heme iron is very high in red meat a candidate mechanism for the effect of red meat Connect with me: Facebook: https://www.facebook.com/DrGilCarvalho/ Twitter: https://twitter.com/NutritionMadeS3 Animations: Even Topland @toplandmedia References: https://www.ahajournals.org/doi/abs/1... https://www.ncbi.nlm.nih.gov/pmc/arti... https://www.tandfonline.com/doi/full/... https://academic.oup.com/ajcn/advance... https://jamanetwork.com/journals/jama... https://www.ahajournals.org/doi/10.11... https://www.ahajournals.org/doi/10.11... https://www.nature.com/articles/ejcn2... https://academic.oup.com/ajcn/article... https://apjcn.nhri.org.tw/server/APJC... https://academic.oup.com/ajcn/article... https://pubmed.ncbi.nlm.nih.gov/19674... https://www.sciencedirect.com/science... https://bmcmedicine.biomedcentral.com...

Felipe Santos Felipe Santos 3 months ago Without discussing the main topic (red meat), this is just one of the best videos about how science works, about scientific knowledge, and evidence-based science. Amazing examples, and the step by step move is fantastic. I had to stand up and applaud when the video ended. Thank so much for this, Gil. Abraços!! 121 Nutrition Made Simple! Kalindu Dissanayake Kalindu Dissanayake 3 months ago After having watched content of hundreds of different channels for years, I can confidently say this is the best health/nutrition channel on YouTube. I can recommend this to anyone I know without any issues. You're doing a service to the whole humanity brother ! 26 Nutrition Made Simple! Michael Kleven Michael Kleven 3 months ago Stellar content, as always. Your treatment of uncertainty gave me chills. Good chills. But there’s one crucial dimension of analysis missing in this discussion on meat: signal strength. Your closing analogy, when compared critically, makes this clear. We know that smoking causes lung cancer not simply because all the studies show it, but because they all show an unmistakably powerful signal. Hazard ratios consistently reach double digits, like in the 15-30 range, if I recall. This is an order of magnitude greater than any effect seen from meat, where confidence intervals often cross unity and HR’s top out around 1.5 (again, my recollection may be imprecise — please correct me). The comparison of meat to cigarettes is therefore flawed. Is smoking bad for you? Yes. How bad? Very. Bad enough to yield an undeniable correlation in every study, no matter how the data is sliced. Is meat bad for you? Probably, kind of, depending on a bunch of things. How bad? Barely. Barely harmful enough to be barely discerned through decades of painstaking research and careful statistical analysis — and still debatable enough to be questioned by some of the smartest minds in medicine and nutritional science. Consistent with your thoughtful, anti-dogmatic approach — which thrills me every time I listen — you suggested several real-life situations in which animal consumption might offer more good than harm. If the actual risk from meat were appropriately quantified and contextualized, we might find that balance tipped toward it even more often. Indeed, many intelligent, informed, health-conscious people have done that. They weigh the real benefits they derive from meat against the small potential for harm and decide, rationally, in favor of it. The same cannot be said of cigarettes. 23 Jonah Wantenaar Jonah Wantenaar 3 months ago Brilliant video! You do a fantastic job at showing both us regular folk and nutrition bookworm warriors how the world of nutritional science really works. Every video is like a master class in nutrition and the mechanisms behind interpreting data so that we can come to our own understanding of the subject with the least biased approach possible. Good job 👍. 9 Nutrition Made Simple! George CHRYSAPHINIS George CHRYSAPHINIS 3 months ago Great content. By highlighting all the variables that can influence study outcomes you help us appreciate just how many building blocks and iterations are required to reach accurate conclusions with any level of confidence. 19 Nutrition Made Simple! Doctor Eye Health Doctor Eye Health 3 months ago Love it, very well done. You inspire me to do some objective breakdowns of eyecare studies. Such as blue light for example. Keep up the fantastic work. 45 Nutrition Made Simple! Berat Danisman Berat Danisman 3 months ago Veeeery nice view and summary on how science operates. Neutral standpoint, humor, critical thinking. Really loved this video👍 13 Geoff Smith Geoff Smith 3 months ago I always enjoy your videos. Thanks for this one! A lot of information to digest, but very helpful for someone like me who has heart disease. I stopped eating red meat several years ago. Might be fine for some people, but with my family history of heart disease, I decided to cut it out of my diet. 6 Nutrition Made Simple! Theron Cooley Theron Cooley 3 months ago I love your content and the balanced way you present it, particularly around this subject. Could you address the so-called antinutrients contained in certain plant foods in a future video? 3 Nutrition Made Simple! t3chw00di t3chw00di 3 months ago As a 60 yr old red meat eater, I await the day when AI can be programmed with all the possible variables and can come to a clearer consensus on what is the real truth. Something as small as having enough Vitamin D3 or K2 in our system could totally sway things because of how it affects our immune systems or how it removes plaque from our arteries. And then there's so much political push for people to eat plant based, mostly because it's more profitable. I doubt I'll live long enough for those results to come to light though. Thanks for making us think. The world sure could use a lot more critical thinking right now. 6 Nutrition Made Simple! Kevin Sandu Kevin Sandu 3 months ago (edited) Doc i freaking loved this video. I almost didn't care about the topic or the outcome, its the whole thought process that became the highlight of your presentation. Thanks so much for putting stuff like this out there for us 5 La Fest La Fest 3 months ago Amazing channel. Reactions I've had throughout a superficial investigation of the matter over a long time compiled concisely and eloquently. You are not just providing quality content but also inspiring respect for the science. Thanks :) 5 Thomas Jefferson Thomas Jefferson 3 months ago This is one of the best videos of this type I have ever listened to. It lays out the scientific method and the step-by-step structure is excellent. In fact, you should use it for every topic you address. So many other nutrition videos jump into describing a piece of the elephant, without context, without a structured approach and leave me more confused than I was before. 1 Sobchak Sobchak 3 months ago Fantastic video, you explained every point very clearly, thanks. I particularly like the part where you say that not knowing everything on a given subject does not mean that we know nothing about it. As simple as it is, it is surprisingly rare to find people who really understand that. 18 Nutrition Made Simple! Lucas Oliveira Lucas Oliveira 3 months ago Amazing content as always Gil! I’m finishing my nutrition science course here at University of Porto and you’re such an inspiration for me! 3 Nutrition Made Simple! MarioPartyGamer MarioPartyGamer 3 months ago Hey been binge watching your videos for a week now, thanks for the content. I wanted to know what your opinion was on hemp seeds? Or they better or worse then chia seeds, and is consuming hemp protein bad because of methionine? 8 Obi z Obi z 9 days ago The problem with the RCTs on red meat is that they focused almost exclusively on lipids. Michael Lustgarten, PhD, who measures every gram that he eats and checks for correlations with his blood tests, saw a detrimental impact of unprocessed beef on his ALT (a liver enzyme), RDW% (the variance red in blood cells size ) and Creatinine (kidneys) 1 The Wopperer Feed The Wopperer Feed 3 months ago I really enjoyed this video! Thought it was very unbiased and really respect the research brought into it. I noticed on your channel you didn’t have anything on Creatine. What are your thoughts on the safety of it and what the science indicates about it? Could you possibly make a video about it in the near future? 3 Enrique Prats Enrique Prats 3 months ago Best nutrition channel on YouTube great stuff no passion just made as simple as it gets (which is still very complex) congrats Doc 3 Nutrition Made Simple! J K J K 3 months ago Great video. Not only on the topic, but on the way scientific research works overall. Finally a channel that confuses you less. Scientific uncertainty is far way better than fake or doubtful confidence. 1 Nutrition Made Simple! josh knix josh knix 3 months ago I really need one of these on diary too, particularly low fat dairy. Layne Norton’s video on dairy, he cites several sources that seem to show that low fat dairy is a healthy food to supplement a mostly Whole Foods plant based diet. I really appreciate all the work you do! 1 Will Sabol Will Sabol 3 months ago Great stuff. Figuring out if nutritional or medical plan is right or the best can only be done on a individual basis because of all the confounding factors. And because of the uncertainty and often the negligible absolute risk reduction, it often boils down to the individual’s personal risk tolerance and lifestyle and comfort level with the plan, not the science. Ariel Malanga Ariel Malanga 3 months ago And thank you for bringing up context - so very important and something I don't hear discussed much. It's much different to be in a modern Western nation than being in a third-world nation where food is hard to come by. People love to fudge statistics to suit their thesis! (Or desires.) 🙏🏼 8 Tim Pete Tim Pete 3 months ago Sounds like a typical 'curse of dimensionality' problem. There are too many variables, i.e., type of red meat, amount of consumed red meat, physical condition of trial participant, and so on. If you would want to vary all of those variables, you might need the biggest study of all time 😁 3 Richie Kirwan Richie Kirwan 3 months ago Phenomenal video Dr Carvalho. Beautifully broken down and explained in a really unbiased way. Beautifully pragmatic description of the scientific process too 1 bengaloux bengaloux 1 month ago Always, and more and more, one of the best if not the best scientific nutrition channel in the Youtube game; and I've been around for years now. The level of your interventions, from an intellectual, epistemological and heuristical standpoint is just first tier. Keep up the good work sir. It's good to have you back. Nutrition Made Simple! RaizaRezende1 RaizaRezende1 3 months ago I believe this is the best video I have ever seen of yours. The medical and Nutrition communities benefit so much for this type of work. I am seeking for more nuance informations always as a student in nutrition. I am studying nutrition and work with regenerative agriculture, so you might understand how the duality between carnivore and vegan (without anything in between) is driving me crazy. Keep it goingm you are doing great. Ah e eu escrevi toda a mensagem e percebi que poderia estar falando em portugues. Muito obrigada. Nutrition Made Simple! Morior Invictus Morior Invictus 3 months ago Awesome video thanks for covering the game/grassfed aspect too. Going to send this to anyone that asks me about red meat in the future. By looking at the science and being as unbiased as possible weighing the possible benefits/risks your video presents a clear picture of the topic. Lifesaving stuff considering how much misinformation is out there. 2 Eduardo Zamora Eduardo Zamora 3 months ago (edited) Loved the video. If I may ask, how do scientists in the studies calculate CHD risk? Is it based on blood tests, apoB or actual coronary events? 1 Alejandro P.S. Alejandro P.S. 3 months ago Hi , Doc. I've just gotten diagnosed with psoriasic arthritis. Do you have any advice in regards to nutrition for this illness? Thanks in advance. Joelho do Poatan Joelho do Poatan 3 months ago I got to know your channel recently and am in love with it -- your videos are clear, direct, and honest. Um abraço do Brasil! 3 llIlIIIlIIliIIll llIlIIIlIIliIIll 3 months ago Great video about the value of evidence and studies but as a look at red meat I thought it was widely accepted it can never be much of a healthier choice for the average person. I was expecting something like an approximation of how much & how often should be harmless in an otherwise outstanding diet (2% by calories once or twice a week maybe) or say a discussion about additives like nitrates & nitrites after all the regular warnings about processed red meats like ham & bacon. 1 Lloyd Olayvar Lloyd Olayvar 3 months ago This is fantastic and helpful discussion on scientific studies on nutrition science. The fact is even in science there's no such thing as 100% certainty. We should just have to patienty keep on waiting for more evidence and in the meantime make food decision rationally based on the best current evidence knowing the limitations of studies. Nutrition Made Simple! Paula Ragoopath Paula Ragoopath 3 months ago 😭😭😭 Great video, very well done. REALLY not what I want to hear though, but I'm listening... I would really love to hear a breakdown just like this for fish, also fruits. As many studies as you can find! There's sooo much uncertainty about whether these are more harmful than healthful. 3 Søren Engelsen Søren Engelsen 1 month ago Great content. Love the scientific approach. Keep it up, mate! Verbalón Verbalón 3 months ago I needed a video like this. Thank you so much! Great content, keep the good job doc :) 3 Patsy Patsy 3 months ago Great video! I wish more people with influnce would have this sort of nuance before blurting out blanket statements to their huge audiences that then follow what they say to the letter. Especially when they have no knowledge about the subject and are already biased. 2 Veganne Veganne 3 months ago Great video as always. This is exactly what people need to need to know about the research. Would love to send this to all those "Health" journalists out there who write headlines like "Red meat is back on the menu" because one study funded by the beef industry "proves" that it's harmless. 6 Jim Vaughan Jim Vaughan 3 months ago Hi Gil, I have heard you mention about reducing Salt (NaCl). The daily recommendation for Chloride to produce adequate stomach acid (HCL) is between 2.5 to 3 grams. This seems necessary for adequate protein absorption and to prevent SIBO (small intestinal bacterial overgrowth). This equates to about 5 grams of salt daily. Do you know if there is any scientific evidence for the benefits of salt intake below this level? Nutrition Made Simple! Weston Weston Weston Weston 1 month ago (edited) Dr. Gil, This segment is excellent. Such high quality content, your regular non science viewers are going to become budding scientists over time. Thanks for the unbelievably free content. Ryan Bishop Ryan Bishop 3 months ago Hey Gil, what's your take on avocado oil? You always mention 🥑 and olive oil, as good mono fats, but I've never heard you say avocado oil (Or maybe you don't need to, because you mentioned the avocado as a whole?) Debug Your Brain Debug Your Brain 3 months ago Planning on doing a video about how empirical evidence relates to our epistemological confidence and behavior and I'll definitely be referencing this video! Great work👍🌱 1 Nutrition Made Simple! Jon Stephenson Jon Stephenson 3 months ago Great video as always! I loved the part about certain foods being “good”, or “bad”, based on circumstances. If you are absolutely starving, eating a Twinkie would be a good idea, compared to eating nothing (at least I imagine). Same with meat for certain individuals who have a hard time getting enough calories in. There is only thing about the major organizations, and their recommendations that I have a hard time with. I wish they would put a little subtext in that explains that many people will have to eat almost no animal products to maintain cholesterol levels that are healthy. I think it’s a little patronizing to know that is the case, but to basically say “well, almost nobody will follow recommendations that are too strict, so let’s soften the blow a little with some anodyne instructions.” Maybe that’s not really the case? Like the video pointed out, research backed recommendations are typically not going to sound cocksure. 2 Hanover 7441 Hanover 7441 3 months ago Doctor thank you so much for another lucid explanation! 1 jayalanlife jayalanlife 3 months ago It's rare that you find such an inflammatory topic so well done (couldn't resist the puns}. As usual your logical and insightful commentary has drawn a line under the controversy. Cheers Alan 3 Seb Stott Seb Stott 3 months ago This is top tier science communication.

Love to see you do a video on THAT. 2 ƦɆᗫŊѦᏒƟϏ ƦɆᗫŊѦᏒƟϏ 3 months ago Great job Gil! You really nailed the science on this one! Nourished by Science Nourished by Science 3 months ago Great video, Gil! Really nicely done. 1 Nutrition Made Simple! David K David K 3 months ago (edited) Hi. What is the reference for the statement that risk increases above 100g/day of unprocessed red meat? Thanks. Great video as always. Herve Del Norte Herve Del Norte 3 months ago Just watched video on another channel that is carnivore oriented and they were discussing the possible cardiovascular harm caused by oxylates found in plants. Some people wrote how badly spinach affects them and how the carnivore diet cured virtually all their ills. Some said veganism ruined their health. This does get confusing. 4 Adam Risch Adam Risch 3 months ago (edited) Ha I worked on some of those AARP meat studies, although I didn't run the models for the particular paper you mentioned. I am named in the references though :). It's great to see familiar studies placed in their larger scientific context - another great video. 2 Nutrition Made Simple! Blue South Blue South 3 months ago Thank you for the very clear and nuanced presentation. 1 Gungus 95 Gungus 95 1 month ago Can you make a video on data corruption and how we can trust the publications? I hear many people say that the sugar industry for example paid to manipulate a lot of data . And around world war 2 there was a heavy bias for pushing process foods for obvious reasons. I assume most scientists don’t have the money to do huge studies unless they’re givin big sums of money. That money coming from food industries with an agenda. Thanks and love the channel 2 Omnipraetor Omnipraetor 3 months ago Fantastic video! Really hits it home with the scientific process. 2 starfthegreat starfthegreat 15 hours ago Great great video! So much bullshit online so it's always a pleasure to find level headed and reasonable content creators 1 keithh23 keithh23 3 months ago Many people on the carnivore diet who say they have problems with plant foods seem to not realize that they are still exposing themselves to the same risk factors from meat. They either say its healthy for their particular set of genes or healthy for everyone. I would think its similar on some scale to most medications prescribed for certain conditions. Whether you are prescribed the medine or not the side effects and dangers of prolonged use still apply. I would think if you had a condition that forces you to eat a restricted diet with many risk factors, you should work with a professional to at least monitor your health. Superluminal Superluminal 3 months ago Excellent as always! Thanks Doc! 2 Micah Gourley Micah Gourley 3 months ago Thanks so much for the honest and transparent breakdown Doc as you 'think out loud' and go over it all for us as we all learn to think critically and 'zoom out' 👍 And then there's this publication from PubMed (which initially confused me lol) which goes into their findings on the ratio of carbs-to-fat in diet and improvements in CV health when restricting processed carbs, which can be found by searching "Saturated fat, carbohydrate, and cardiovascular disease" by Patty W Siri-Tarino 1, Qi Sun, Frank B Hu, Ronald M Krauss. In timpul liber In timpul liber 1 month ago We should also, not look just from the perspective of longevity? Im very curious, if on average people who eat more red meat have more muscle, stronger bones etc. Yes, it would be correlational and probably a modest effect, but thats the case too with the longevity aspect 1 mathias brænder mathias brænder 3 months ago Please do a video about the nightshade famiy. This is a really confusing one for me, because event doctors tells to avoid the nightshades when you have an autoimmune disease, despite not much actual research on the topic is present 1 AmBerLAnd AmBerLAnd 3 months ago I just saw another video by another scientist saying that none of these studies even matter as it’s practically impossible to isolate red meat with other variables. It’s a long video and I suggest everyone to watch it. Now, I’m no carnivore or vegan or anything tbh. I eat clean, meat, veges (quite a lot tbh) so I don’t bias any sides. However I do have a question. How does the researchers isolate (or at least tried to) isolate red meat? How do they not include the buns with the meat on a hamburger, (for example), especially on n=millions like these studies? isn’t it practically impossible mathematically? I really hope you could make a video on how these studies are conducted especially the epidemiological ones. thanks doc ❤️ 1 Nutrition Made Simple!

NonStopGaming15 NonStopGaming15 3 months ago Should already have way more views. Very important information! 1 Simon Toth Simon Toth 1 month ago Man, stop! You're making everyone else in the space obsolete. In all seriousness, consumable content for the leyman on nutrition of this quality does not exist anywhere else, period. Thank you! Jeff Howard Jeff Howard 3 months ago Round of applause - another brilliant video! 1 Toby Windgassen Toby Windgassen 3 months ago I just want to explain, in classical logic it refers to the type of argumentation, induction, as giving us a probability as opposed to certainty and this type of argumentation, induction, is what science uses. So if you accept classical logic of course we don’t have 100 certainty of anything in inductive inferences because that’s not a defining characteristic of induction. In opposition deduction is said to provide use with certainty. It is ‘conclusive’ supposedly. I recommend you read critical reasoning for beginners by marianne talbot director of studies at Oxford university just to learn this stuff, or if you don’t want to pay you can view her lectures on logic on YouTube for a generally similar if not a bit more flawed presentation of the concepts. 1 Nutrition Made Simple! Tien Truong Tien Truong 3 weeks ago i hear ALOT of people who espouse the carnivore diet talk about how it's impossible to control for the healthy user bias, but the studies you talked about that did, showed an increase in risk factors. That's alarming. David C David C 2 months ago Are there any differences when consuming grass fed/finished compared to grain fed? Killian Chellar Killian Chellar 4 weeks ago (edited) Your videos are bloody amazing. Congrats 👏 leetpg leetpg 3 weeks ago (edited) Why does everything seem to make one of the simplest things(eating) so difficult? You previously replied to one of my comments on another video about my blood pressure and the carnivore diet. I've been strict carnivore for 3 months now. All blood work is perfect with the exception and expectation of LDL. I've consumed almost 0 carbs every day, with the odd day having some berries etc. My blood pressure is stable 122 75 at rest. I'm now going to go back to normal eating for no other reason than my general concern with long term 3x a day of meat only(red, white, fish or organs). What do you believe to be the overall most accepted diet for general health and well being? I don't experience bloating anymore. I pass stool once a day, perfectly and on time every time. Apart from my LDL number playing on my mind, I've never felt better, ever. I did have some onions with my steak about two weeks ago and suffered some extreme cramping and gas. I just don't know what to do. I feel so good now but it's not sustainable and there is no long term study for what I do. The vast majority of my meals are not processed. Occasionally I have bacon or home made sausages. I'm from Australia. I'll pay you for some time via email. Happy to chat and send you blood work. Nutrition Made Simple! Aziz Kash Aziz Kash 3 months ago Thank you for the objective approach. 1 Joe Joe 2 months ago Great video! How do you know when the scientific evidence is strong enough for you to say that something is scientifically proven / scientific fact? I appreciate we can never be 100% sure of anything, but there must be some way to tell when something is likely, e.g. red meat causing heart disease, vs something we are completely sure about, e.g. life on earth is the result of evolution, or smoking causes cancer. 1 Wade Humeniuk Wade Humeniuk 3 months ago (edited) In terms of health how much of a percentage do nutritionists attribute diet to good health? As opposed to genetics, exercise, geographic location, etc, etc, …. Edited: I think I answered my own question. In some cases someone can have poor health because they lack nutrients, so 100% attribution to poor health and even death in that case. An then somewhere between between 30%-100% for all not just nutrition related? Just like your 100% scale in this video. Not that I can even define good health.

Thank you for sharing this! 1 Jimmy Tanico Jimmy Tanico 3 months ago Doc. Love, love, love your fact based and scientific approach. (Too bad we didn't do that with our politics). Unfortunately I am now confused. I'm 63 and have been strength training most my life and now in the battle of age related muscle loss. At 150 lbs I'm looking for at least 125 grams protein per day. I'm also a late stage rectal cancer survivor. Since watching your videos I'm switching to plant based eating but not looking to go completely vegan. What then is the best way to get to my protein needs? I was eating mostly fish, then chicken and trying to keep read meat to 5 or less servings per week. But now I'm thinking the stuff is radioactive. Confused in NY. Nutrition Made Simple! Masher Masher 3 months ago Great video! Is there one on red meat and cancer coming up? Athlete Training Centre Athlete Training Centre 3 months ago Great 👍 video and content In 2015 the World Health Organization labeled red meat (beef, pork, lamb) as a probable carcinogen As for Coronary Heart Disease my question is what is the probability of having that disease and a heart attack if one’s nutrition is based on a Whole Food Plant Based diet? 1 David B David B 3 months ago (edited) Is it the red meat, or is it the fact that a large portion of the red meat consumed in Western countries is fried, slathered in sugary condiments, topped with refined white bread, and served with a side of potatoes fried in oxidized industrial oils and washed down with a super-sized sugary drink? Dr. Carvalho referenced a study where they did a subgroup analysis of healthier eaters and found that red meat consumption demonstrated a stronger negative trend than among less-healthy subgroups. However, even here you do not know if the effect is the red meat or the fast-food effect, because there is going to be a spectrum of fast-food eating behaviors even within the healthiest quartile, and this was not controlled for in the researchers' analysis. Here is a study looking at the effect on cardiovascular disease of eating out in general: https://pubmed.ncbi.nlm.nih.gov/33775622/ It's interesting that, in the above study, the magnitude of the hazard ratio for eating out is greater than magnitude of the hazard ratio for red meat consumption in the study referenced by Dr. Carvalho. Still, you don't know if it's because people in the above study were eating out more, or because they were eating more red meat, since fast-food restaurants disproportionately serve red meat over white meat and fish. In order to tease out the the effect of red meat versus the fast-food effect, you would have to 1) do your study in a population where people don't eat out, or 2) do your study in a place where fast-food restaurants serve equal amounts of red meat, white meat, and fish, or 3) do your study in a place like the USA, but try to control for frequency of eating out. If anybody is aware of such a study, please let me know. The issue is vital. As a physician, where should I be putting my efforts? Encouraging people to eat less red meat? Maybe; I'm still not sure; I'm keeping an open mind. The heme iron mechanism is an interesting hypothesis. Or should I encourage people to eat at home more? The answer may be both, but I suspect the latter would have a much greater impact on public health. 11 Chuck Luther Chuck Luther 3 months ago Awesome explanation sir! Nutrition Made Simple! Betty M Betty M 3 months ago (edited) My latest understanding of health is that it's not just about food and excercise and toxins that affects our risk for disease and early death. I've listen some tog Dr Gabo Mate and read some about placebo. Our psyche and last trauma has some to add to it too. And our gut health!!! I think this is why this is comfusing! Our body types, genes, and toxins are just a part of it! (Started writing before I finnished this video 😅) The best thing I've done for my own health is to start listen to my own Body and it's signals. To educate myself about nutrition and the signs of malnutrition of some kind. Stress less. And don't believe everything I hear. Still not judge the info as good or bad but to compare what I know with other things and be curious about life and how things work. And most important of all. Some works for me, but may not work for others. So why then does it work for me?! I'm not perfect, but I love to learn! Still learning! This thing that science doesn't get it 100% in everything just tells even more how amazing and complex this life is. Ecclesiastes 8:17 then I beheld all the work of God, that man cannot find out the work that is done under the sun: because however much a man labor to seek it out, yet he shall not find it; yea moreover, though a wise man think to know it, yet shall he not be able to find it. mark p mark p 3 months ago The only real confusion is about how to cook it 😂, great video as usual! 2 Some Guy Some Guy 3 months ago How does the certainty of the detrimental effects of red meat compare to the certainty of smoking tobacco? CursedKitten1 CursedKitten1 3 months ago First video ever that has convinced me to reconsider eating unlimited red meat. I really like this style of examining the evidence, because 90% of those questions and confounding factors crossed my mind but I don't have the time or expertise to find all the relevant studies. 5 C. Anderson C. Anderson 3 months ago Nice presentation on interpretation of evidence. 1 Toby Gosling Toby Gosling 3 months ago Yet again another great video 👍 AI21 AI21 2 months ago I do like your style of presentation. Very even sided. But, let me throw a wrench into the argument. Inspite of all the Official guidelines and thinking, what if the original hypothesis on saturated fat and cholesterol still remains just that, an HYPOTHESIS!! as you just pointed out very eloquently no test is 100%! There is a large amount of research refuting the heart cholesterol theory, that LDL isn't the only marker, that fat isn't bad as labeled, and still pointing back at sugar content as culprit, can all agree about sugar at least?one last point. The trials usually point at RISK and that risk is based on the outdated ideas about sat fat and lipids, which is becoming more and more debated. Thanks. 1 Chad Jessup Chad Jessup 3 months ago So, the main difference between white meat and red meat is the presence of oxygen bearing molecules in the latter. So, myoglobin is causing the CHD? Doubt it. But investigating its iron binding properties might yield some interesting information. I descend from a long line of dairy farmers and ranchers who lived into their late 80's and 90's. Only my relatives who were very overweight perished in their 70's. I greatly appreciate the information you present here, and I thank you for that. Your meat-ometer is misleading, as it adds together one "limited" study (i.e. studies with too many unaccounted variables) on top of another. 4 Herve Del Norte Herve Del Norte 3 months ago Great summation! Luckily not all of our gained knowledge in life requires multiple random control trials over decades to elucidate the truth. (E.g. If the stove is hot, don’t put your hand on it! No study needed). 😁 Nutrition Made Simple! Albert Cloete Albert Cloete 3 months ago You've quickly become my favourite nutrition channel. Is there any way to support your channel? Nutrition Made Simple! Phillip S Phillip S 3 months ago I find myself curious to know if the monetary/funding sources of studies (mentioned in this video) that show a disadvantage to eating red meat are from the food industry and LDS church. That has been very revealing in terms of bias in other studies that show that red meat is harmful. 1 Korea Kingy Korea Kingy 3 months ago This is a video everyone needs to see. 3 Richard Doan Richard Doan 3 months ago Great video on nutrition science. But even though you talk about the limitations on certainty, you present a lot of studies (and the rising meter) strongly suggesting that red meat is unhealthy and suggesting a strong picture. That may be the case, but I suspect you actually didn't intend to do that, and would have approached it differently if you were. elimar48 elimar48 3 months ago 16:22 and onward is a little bit of a let down because it seems to take a "well just throw your hands up in defeat" attitude (to some degree) for interpreting the data and skims over the question that I think is missing from all the studies showing increased meat = increase all cause morbidity etc. The studies never address the question of whether it is the interaction of that red meat and carbs that causes the health issues. I think it would, like you said in your video, help adjust the confidence meter if we were able to decouple the effects of red meat combined with carb consumption. Its a hypothesis that should be tested at least, because it would be helpful to address the seeming contradiction (in the face of all the standard red meat studies) of people doing so well health-wise, physical appearance-wise, and bloodwork-wise that tons of people who do Keto experience. 9 RJZ L Wop RJZ L Wop 3 months ago Amazing Monday to you thank you so much for sharing this information with me I really really thoroughly enjoyed it have a great day 1 ABfan97 ABfan97 3 months ago Thank you for making this... perfect timing 1 ترجمات ترجمات 2 months ago "A gradual reduction of uncertainty." Beautiful. Nutrition Made Simple! Doug M Doug M 3 months ago Great video! I think people have evolved to think in terms of black/white, because their ancestors have had to often make life or death decisions with limited information. "Do I walk into these dark woods or not?" You can't make 70% of a decision, so talking in terms of probabilities causes everything to short-circuit - especially if everyone has a "grandfather who smoked a pack a day and bathed in bacon grease who lived to 101." I have a question about the hazard ratios. If the HR is 1.3 per 50 grams of meat, is there a 60% higher risk for someone who eats 100g/day? It seems as if there are diminishing returns/non-linearity, otherwise the hazard ratios would approach ludicrously high levels with higher doses. 2 Popcoin Gaming Popcoin Gaming 3 months ago Has there been any studies on people who ONLY eat grass fed red meat with risk of CHD? 3 Henrik Luthman Henrik Luthman 4 weeks ago This is very complex... Or...is it that our lifestyle/food makes our fatty metabolism turned off and due to that we have to high lipid concentrations in our blood streams... And then we have the lack of sun light which in turn don't metabolise cholesterol into vitamin D... One thing is for sure...we are suger pumped... Emre Emre 3 months ago how can they factor out non-healthy diet if we dont know what a healthy diet is? just by trialing red meat along with a "healthy diet" you could in fact have unhealthy foods be factored in, which makes the claim that red meat shows signs of even higher CVD with "healthy diets" a bit weaker. red meat actually has a very nice convenience here; you can trial its effects in an isolated way, as its possible to eat solely red meat. of course this will then be less indicative of the effects of red meat alongside a "typical" diet, but at least it can be verified more purely if it increases chances for CVD.

Karunamayi Holistic Inc. Karunamayi Holistic Inc. 3 months ago Hello, will you mind doing one of your upcoming videos on dairy? I understand you are also a vegan soy promoting doctor I believe. But because you give pros and cons of each study, I would love to hear from you if dairy in vegetarians have been found to be significantly linked to prostate cancer, or other diseases. If it is then all the pros and cons you mention, I would be happy to hear it. Of course it doesn't make me lose my trust in it because I sincerely feel it is when and how a person eats or lives on a holistic level determines everything Not dairy or meat alone. I do understand that pizza topped with excess cheese can not be a good thing. Fat without enough fiber just on top of wheat and bread and grains can never be a solution. But still I would be happy if you reflect on some of the studies on dairy too in future. Thank you 🙏 David Trong Nguyen David Trong Nguyen 3 months ago Hey doc!

Chris Zinn Chris Zinn 3 months ago I’m definitely a red meat eater and more towards keto and carnivore. I watch a lot of your videos and like your take on diet. And I always like to here both sides even if I disagree. I’m not sure if I’ll always eat the way I’m eating now but I’m always open and always looking. Plus I think there’s many different paths to get healthy. Not a one diet fits all. 6 Nutrition Made Simple! Emanuel N Emanuel N 3 months ago Hi, I have a question. Do you have any thoughts on the SWAP-MEAT trial from Stanford? CantFlipForShip CantFlipForShip 3 months ago Best video I’ve ever seen on the topic 1 Morphable Morphable 2 weeks ago How about meta-analysis of RCTs that show the opposite? Let's take for example L. Lauren et. al. work "Total red meat intake of ≥0.5 servings/d does not negatively influence cardiovascular disease risk factors: a systemically searched meta-analysis of randomized controlled trials". There are various meta-analysis papers that show there's not a sufficient statistical correlation. This one for example "Dietary cholesterol and cardiovascular disease: a systematic review and meta-analysis " went through 40 studies and concludes "Dietary cholesterol was not statistically significantly associated with any coronary artery disease". In fact, there are studies that show that low ldl is associated with increased risk of stroke "Low LDL-Cholesterol Levels May be Associated with Elevated Hemorrhagic Stroke Risk". We can also take a look at what people eat, not just cherry-pick "the mediterranean diet". For example, Hong Kong has one of the highest meat consumption per capita in the world (about 0.5kg/person/day), yet they have one of the highest life expediencies and a much lower heart disease rate than some Mediterranean countries like Morocco/Tunisia (they cook almost everything in olive oil). India, where red meat consumption is very low, has also a very high heart disease rate. Would be good to take the other works into account and not just pick ones that go in the same direction. Nutrition Made Simple! Kreed2k Kreed2k 3 months ago (edited) The studies are clearly missing something as countries with the highest meat consumption such as New Zealand, Luxembourg, Argentina, Brazil, France, Chille, Saint Lucia etc have the lowest rates of heart disease yet countries with the lowest meat consumption such as Ukraine, Syria,, Yemen, Moldov, Bulgaria etc have the highest rates of heart disease. Even when you break it down further to red meat consumption the story is still the same. There is clearly something that isn't being accounted for in these studies as the strongest data points in the opposite direction.
