Lipotossicità: come i grassi saturi aumentano la glicemia

Il motivo per cui coloro che seguono diete a base vegetale hanno un minore accumulo di grasso nelle cellule muscolari e una minore insulino-resistenza potrebbe essere dovuto al fatto che i grassi saturi sembrano compromettere controllo della glicemia di più.

Questa è la terza di una serie in 3 parti, a partire da Che cosa causa la resistenza all'insulina? (http://nutritionfacts.org/video/What-Causes-Insulin-Resistance) e L'effetto di ricaduta collega l'obesità al diabete (www .nutritionfacts.org/video/the-spillover-effect-links-obesity-to-diabetes). Avrei voluto inserire tutto in un video, ma sarebbe stato troppo lungo.<br/>
Anche se i grassi saturi non fossero associati alle malattie cardiache, il gli effetti sulla funzione pancreatica e l'insulino-resistenza nei muscoli sarebbero sufficienti per evitarlo. Nonostante i resoconti della stampa popolare, l'assunzione di grassi saturi rimane il principale determinante modificabile del colesterolo LDL, il fattore di rischio n. 1 per la nostra malattia cardiaca killer n.

Quanto basso dovremmo puntare in termini di assunzione di grassi saturi ? Il più basso possibile, secondo il National Academies of Science Institute of Medicine degli Stati Uniti: Trans Fat, Saturated Fat, and Cholesterol: Tolerable Upper Intake of Zero (http:// nutritionfacts.org/video/trans-fat-saturated-fat-and-cholesterol-tolerable-upper-intake-of-zero/).

  1. This is seriously messed up. This was posted today 10 February 2015 and it says January 29. No wonder these videos get no views anymore. Not even in my sub box, I come to check every other day if there's something I missed.

  2. A few years ago, I was low carb, mostly primal. My blood sugar wouldn't get below the 140's without a lot of extra insulin. Even when my carbs were under 50 a day. Now, I'm vegan and my carbs have increased to 3-400, daily and my insulin needs have been cut in half. It's great to have the science behind WHY. Thank you!

  3. I have been on LCHF diet for a long time now …. this video is chock full of bull shit. I have lost over 50 pounds, off of all my diebetic drugs except metformin and my blood sugars are NEVER over 100… anything to sell some snake oil, eh?

  4. I see totally the opposite in my Functional Medicine practice among patients who go on ketogenic diet.  Their diabetes goes away and their lipid panel corrects, and I do the expanded VAP panel.  How did you come up with that Big Fat Lie on a website called NutritionFacts.og?  ?

  5. Hey, The best success that I have ever had was with Marks magicplan (just google it) Without a doubt the most helpful diet that I have ever tried.

  6. I watched this while eating some eggs, chicken breast and a side of kale cooked in grape seed oil. The meal was seasoned with pepper, salt, and crushed red pepper.

    Thanks for the info Doc very informative.

  7. I'm supposed to believe eating something that is not glucose will increase glucose levels? I can't wait for the next video by this guy, "How Drinking Water Raises Alcohol Levels in the Blood". This guy is making up his own science to fit his diet dogma.

  8. Who's gonna believe this if refined carbohydrates are out of the equation. This is no science, just wanna make us follow like sheep.

  9. Basically all this video really breaks down to is, if you eat starchy carbs with fat you are more likely to store fat. This video really does not look at something like a ketogenic or Paleo diet vs vegetarian. It looks like the basic western diet vs vegetarian diet.

    The effect of ketosis on fat is clear. Nobody on the ketogenic diet is suffering from chronic inflammation. This is just more bias garbage from this guy.

  10. For once I am impressed that many of the comments on a youtube video actually make sense. This DR Gregor is dangerous and what he is peddling could actually kill you. DO NOT listen to this hack. The science behind this is clear. Guidelines around sat fat have already started changing to reflect the science. He is either overtly lying or the worst doctor on the planet.

  11. How can you teach doctors that there is a difference between saturated fat in the presence of high carbohydrate and saturated fat in the presence of low carbohydrate?
    Also, I think that the tone of the presentation suggests that he's selling not teaching.

  12. can someone explain exactly as to why animal products are more insulinogenic? we know their glycemic index is low, but that is a poor indicator of whether its a healthy food or not. please respond!

  13. Dr Greger, you don't know what you are talking about. Lies, lies and more lies. I eat lots of organic butter, coconut oil, chicken, red meat, bacon and also lots of eggs. I am very healthy along with everyone eating this diet. I do not have insulin problems.
    They want you to eat the poison "man made margarines" and go on low fat diets that are high in sugar. Diabetes is caused by the bad fats not saturated fats!
    People have become very obese from eating take away food (trans fats)and lots of sugar.
    Best diet is saturated fats with low amount of carbohydrates. See Dr Eric Berg's videos online – he is 50 and looks great.
    He explains that fat burns fat….and it is true! Saturated fat increases your "good" cholesterol. Your brain needs cholesterol and so does every cell.

  14. All those opposing Dr. McGregors view point, comment below a counterpoint to his research but USE research. Not anecdote. Cite your arguments and do it without harsh criticisms or rude words. That's what McGregor has done here, I don't see him belittling others and providing anecdotes. This is how we learn collectively, by stating research and being open to alternative viewpoints. There is NOTHING wrong with viewing differently from him, but people will take you seriously if you bring forward a strong argument.

  15. You can watch a video by a Vegan on Lipids & Saturated Fats but you know what the message is going to be without even watching the video OR you could watch video's FROM LIPIDOLOGISTS !… The Doctors that specialize in & study Lipids 😉
    Dr. Thomas Dayspring & Dr. Sarah Hallberg.

  16. sorry but the chemistry dictates that fat does not cause any inflammation. You can eat the burger but the sugar in the ketchup and the carbs in the bun are what cause the inflammatory response.

  17. This is not completely accurate. their studies are skewed towards a specific outcome. It is not easy to gain weight if you consume only fat and protein. Now if you add simple carbs to the mix you will inflate like a balloon. I have eaten mainly fat and protein for 6 months. I have lost weight and my blood sugar is normal… I was diagnosed with diabetes a year ago.

  18. ❤️❤️❤️❤️🔬 i love man!!!! eres un gran aporte en el mundo de la medicina y nutrición.
    Nunca dejes de investigar!!!!

  19. How long does it take for the increased fat in the blood to clear? Are there any ways to speed up the clearing of fat in the blood?

  20. I've never heard so much gabbage peddled as healthful information. I sincerely people are not buying this. If you are serious about preventing type 2 diabetes which will manifest initially as insulin resistance, then keep your triglycerides to not more than 75. The best way to do that is reduce carbs and increase saturated fats.

  21. When I stay on a vegan diet, my blood sugar stays in the normal range. When I decide to eat meat, my blood sugar goes up. The longer I eat meat the higher it goes and the longer it takes to come down when I go back to a vegan diet. I am able to not use any medication like metformin to control the blood sugar once normal levels are reached to maintain those levels. As for triglycerides​, I have normal levels by avoiding sodas and eating alot of fiber and resistant starch.

  22. This is only addressing half of the problem.

    Read this article . . . "β-Cell Glucose Toxicity, Lipotoxicity, and Chronic Oxidative Stress in Type 2 Diabetes" which is a larger picture of what is happening but it is still not the full picture which may have to do with antibiotics and the human microbiome

  23. If saturated fat is so bad for your health then why do the Hunza tribe in Pakistan live on average above a hundred? Those mofos eat roasted lamb practically every day ffs

  24. What is worse, lard/ghee or plant oils that are liquid? I think the question need not arise for it amounts to the same. Isolated fat is the quintessential processing of food.

  25. When I was eating meat, I was scared I'd put weight on if I went plant based, I'd been listening to all this garbage about how carbs leads to high insulin which causes weight gain. I gradually reduced animal products and I'm now over two stone lighter than I was.

  26. How do you measure the funtion of beta cells?, if it´s for the amount of insulin, I´m not agree, because obviously vegan consume much more veggies than omnivores, and veggies has too much magnessium and potassium, and these two minerals, makes raw material to produce insuline.

  27. Both LCHF and HCLF had good results at improving lipid profiles and inflammation. What they have in common is that both resign from PUFAs seed oils. I would say fried PUFAs are worse than saturated fat.

  28. The main cause is high fat diet folks..poor glucose metabolism is a buildup of lipids in muscle tissue and liver. Drop your fat (All fats) intake to 15% total calories and problem solved simply by turning on the insulin signaling process within the cells..
    In two weeks time your insulin sensitivity will increase greatly..

  29. But, we as Americans over the decades have been eating less and less saturated fat, yet the rates of Diabetes keep going up?

  30. So, if you eat a lot of fat/saturated, it blocks your cells from taking in glucose/insulin?
    And it makes no difference if it is fat that you eat, or fat that is in your own body … it will have the same affect? So, why are not all fat people diabetic? Would fat people in the process of ketosis or losing weight be prone to diabetes?

  31. Interesting video. I'm not diabetic but have a blood glucose meter just for experiemental purposes. I can eat god knows how much saturated fat and see no change in blood sugar – but when I eat a high carb meal I get a pretty good spike even if I've not had any saturated fat in the last few days. I twice performed a weight gain experiment, where I gained substantial weight (which should theoretically make me insulin resistant), once with carbs, and once with fat (I actually drank cream neat for 3 months – don't try this at home). On the carb weight gain diet my blood sugar rose high every evening and would barely come down for hours. I went from 155lbs weight to 180. On the next experiment, (after losing weight the first time) I started at 149lbs, and drank 1000 calories worth of cream every day for 3 months. I reached 180lbs. I then tested my blood sugar (10 times in the day). If was totally flat lined regardless of what I ate. Please Michael Greger explain how I could gain even more body fat on saturated fats than with carbs, in less time, and have NO increase in blood sugar, unlike when I gained on carbs? My experiment was quite extreme and I had to stop the second one (with cream) early because of severe headache issues that started, however.

  32. In what world do saturated fats cause free radicals, they are extremely stable, that's why, as warm blooded animals, we produce mainly saturated fat

  33. There's no such thing as a vegetable fat. Have you ever tried to squeeze a fat from a vegetable?
    You can rip oils from seeds in a factory but they have to be bleached and dyed and flavored.
    All oils and fats contain saturated fat, there isn't one that doesn't. Coconut oil contains 95% saturated fat. It's the best.

  34. I just don't understand why other scientist who spout other studies that state excess sugar is the issue do not recognize these studies.

  35. I eat only meat, eggs, milk and cheese. 153 pounds. Unhomogenized and unpasteurized butter. The butter at stores is unhealthy and dead calories.

  36. diabetes cure worth 15 billion annually

    https://cancerdone.blogspot.com/2022/07/diabetes-cure-worth-15-billion-annually.html

    2002 and three medical professors published the use of High Intensity UltraSound to clear all 200 cancers plus a every viral and bacterial infection in one session.

    Every registered Dr. On earth rushed to acquire an 8 W MHZ unit: I utilised an 8 W one MHZ unit. 1 minute will clear all 200 cancers out there! Applied externally to where it hurts.

  37. diabetes cured 2013

    https://cancerdone.blogspot.com/2022/07/diabetes-cured-2013.html

    That year I applied ½ minute of High Intensity UltraSound to the bottom right and my friends chest over the pancreas: this was that high frequency sound waves, as medically proved 2002 to clear the viral structure causing cancers.

    I it did not know it, but if you don't ultrasound scan of a diabetic pancreas, it gives off X rays. As the ultrasound sets off biological molecular nuclear fusion: I was studying nuclear fusion at Sheffield University 2000, and discover that ultrasounding liquid water sets off nuclear fusion.

    1 H₂O+P+US→He+O+E+X-ray so the pressurised diabetic infected cells, give off X rays. As her pressurise nature does water into helium and oxygen gases, plus massive heat.

    I was just trying to relieve use diabetic discomfort! I was staggered to clear his diabetes type two totally in ½ minute. That was not expected!
