Colesterolo e malattie cardiache: perché ci sono state così tante polemiche?

Il ruolo del colesterolo nelle malattie cardiache è assodato oltre ogni ragionevole dubbio?

I video che ho citato sono:
• Come sappiamo che il colesterolo causa malattie cardiache? (https://nutritionfacts.org/video/how-do-we-know-that-cholesterol-causes-heart-disease/)
• Livello ottimale di colesterolo (
https://nutritionfacts.org/video/optimal-cholesterol-level/)
• Quando basso rischio significa alto rischio (
https://nutritionfacts.org/video/quando-basso-rischio-significa-alto-rischio/ )<br/>
Attribuisco l'analogia con il pilota di caccia high-tech al Dr. Ted Barnett, per il quale nutro un enorme rispetto. Dai un'occhiata al suo Rochester Lifestyle Medicine Institute (
https://rochesterlifestylemedicine.org/) e considera di fare uno dei suoi programmi jumpstart.

Che dire delle particelle di colesterolo “soffici” rispetto a quelle “dense”? Vedi La dimensione del colesterolo è importante? (https://nutritionfacts.org/video/does-cholesterol-size-matter/).

Il colesterolo può diventare troppo basso? (https://nutritionfacts.org/video/can-cholesterol-get-too-low). Guarda il video per saperne di più.

Nel prossimo video, esaminiamo la principale fonte alimentare di colesterolo. Vedi Il colesterolo alimentare (uova) aumenta il colesterolo nel sangue? (https://nutritionfacts.org/video/does-dietary-cholesterol-eggs-raise-blood-cholesterol).

  1. Six years in vegan diet don't get me wrong I love it I did it for healthy reasons in those years my total cholesterol was 129
    HDL 27
    LDL 88
    Triglyceride 77.
    I did exercise and consuming walnuts, almonds, brasil nuts, pistachios, pumpkin seeds etc my cholesterol was the same.
    In April this year I switched overnight to carnivor and I feel great after six months my total cholesterol 225
    HDL 86
    LDL 160
    Triglyceride 34.
    Explain my Hdl and Triglyceride.

  2. Thanks for this video. I have friends who are still doing keto, insisting dietary has nothing to do with serum cholesterol levels, and I fear for them. Their assertion that french fries (with ketchup, of course) count as two veggies makes me cringe.

  3. Thanks for speaking the truth. People are ill largely (but not exclusively) because of their lifestyle. You can lead a man to knowledge but you can't make him think.

  4. It’s well understood in lipidology that dietary cholesterol has nearly no effect on serum cholesterol unless you have rare and specific genetic disorders. The forthcoming propaganda to the contrary will be cherry picked low quality studies provided without proper context, as always.

  5. Yeah…well how do you lower ldl….i lowered my total cholesterol from 145 to 113 by low fat pb eating…but ldl remained at 70.

  6. Oddly enough the Maasai had very low cholesterol levels of around 140 mg/dL on a mostly animal based diet. And people with gum disease have much higher rates of heart attack no matter what diet they are consuming. What foods cause dental disease? Think about it.

  7. And Dr. Berg, just released a video highlighting the harm due to low cholesterol.
    Wonder where he gets that information from and the confidence with which he spreads that information.

  8. I just viewed a video last night that explained the whole thing in depth by a cholesterol expert. The correlation between dietary cholesterol and serum cholesterol is not as clear cut as you describe. It all has to do with a persons cellular ability to absorb and reject cholesterol.
    Dietary cholesterol is only responsible for a fraction of the cholesterol in a persons blood. This video explained it all to me. https://www.youtube.com/watch?v=GkWMDnTyxfo

  9. Love your videos – I've been WFPB 4 years – love it. I know that information can be spun to make anything sound plausible, but some carnivores out there sometimes profess things that sound – like – plausible. For example, a youtuber (BK), states that the reason why there is diabetes is not because the fat is not allowed in the cells, but the blood sugar content is high – Diabetes is too much blood sugar and not the fact that glucose can't enter the cell. He states that if consuming no sugars, starches of any kind, fat is not plugging up you cells, but the body is doing exactly what it is meant to do – cells are living off fat (ketones). It's hard to debate this when "we" say that glucose is not able to enter the cells, and they say that glucose is not supposed to enter "most" cells. (the little glucose that is needed for some cells is produced by the body). I think that it would be outstanding if you could enter into an online debate with this person. Oh and if you do, be prepared, all science out there is incorrect except for his science. I have to say some of his arguments sound "sound", but because I have researched WFPB for 10 years, I can pick up on the falsehoods he states, but there are many people out there who because they have not researched significantly, could possibly be misled by all the "spin-ery). I'd love to have you debate this person. I think that there are not enough debates out there anymore and the world and this platform would greatly benefit from such a debate. WHOSE WITH ME? Peace and love❤

  10. Thank you for continuing to shine a spotlight on this topic. Where I believe most of the confusion comes from is that there are two schools of thought on this topics. School A: Dietary Cholesterol and Cholesterol in your body are the same thing (i.e. you eat high cholesterol foods, your cholesterol goes up), in other words, a direct linkage and School B: where it is viewed that dietary cholesterol, when consumed is esterified, and not directly consumed by the body, but goes through another pathway (as described in the below video)…..assuming that metabolic pathway is "health" or results in appropriate cholesterol regulation…excess cholesterol is excreted…in others words, there is no direct linkage between high cholesterol consumption to high cholesterol levels in the blood….it probably goes without saying, an indirect relationship exists and, high cholesterol foods, generally negatively impact metabolic health, lead to poor cholesterol regulation in the body, and so on…. Would really love to hear your (Dr. Greger) throughs on Dr. Attias view on this…Thanks!

  11. "Choline Intake as Supplement or as a Component of Eggs Increases Plasma Choline and Reduces Interleukin-6 without Modifying Plasma Cholesterol in Participants with Metabolic Syndrome"

    "A recent study found no change in plasma LDL-C concentration in a MetS population consuming three whole eggs/day vs. a yolk-free substitute for 12 weeks [8]. Conversely, an increased prevalence of large LDL particles and a decrease in small LDL particles was also reported [8]. Therefore, egg yolk, although high in cholesterol, is considered to have beneficial health effects on lipoprotein profiles in people with MetS, potentially due to both, the formation of less atherogenic LDL particles [9], and their high phosphatidylcholine (PC) concentration [19]. Recently, the Dietary Guidelines for Americans (2015–2020) removed the recommendation to limit dietary cholesterol to ≤300 mg/day [20]. Regardless, due to their high cholesterol content, people with MetS continue to be cautious regarding egg intake."

    "In conclusion, three eggs/day did not increase biomarkers for CVD, specifically LDL cholesterol, in people with MetS. Moreover, eggs did not negatively affect any of the biomarkers of MetS, while improving the inflammatory marker IL-6. Eggs also improved HOMA-IR and decreased plasma insulin. Eggs are a good source of choline thus consumption of eggs enables individuals to achieve adequate intake of this nutrient. Therefore, whole eggs could be considered a healthful food choice for people with MetS."

  12. NO SUCH THING AS BAD CHOLESTEROL ! CHOLESTEROL IS A SCAM ! MOST PEOPLE WITH HEART ATTACKS AND STROKES HAD "NORMAL" LEVELS OF CHOLESTEROL. VEGAN FOR LIFE BUT CHOLESTEROL IS A SCAM ! STATIN DRUG INDUSTRY INVENTION ! FOLLOW THE HISTORY ! ANIMAL PROTEIN IS THE PROBLEM !

  13. Maybe it´s a consequence, not a direct cause. The cause is overeating, though undermoving also helps a great deal. CVD is a thing of the people that eat too much, not of the people that eat much too little (with the possible exception of heavy ultraprocessed eaters).

  14. Everything is easy: before of vege era(oils, margarine, etc) , heart problems and obesity were an extremely rare. Go back to golden era, the one with a lot of animal products!

  15. My husband eats almost nothing but the top high cholesterol foods yet last time his cholesterol was measured it was normal. How is this even possible? Does he digest cholesterol better? He doesn't eat after about 4 pm though because he'll get sick. I can't get him to stop. I told him he could get rid of his acne by quitting dairy and he did stop adding milk to his coffee, but that doesn't help when you're still eating cheese and pastries!

  16. you know what would have been nice is if the good doctor would have explained the actual mechanics of HOW cholesterol caused the heart disease instead of citing quotes post conclusions.

  17. My dad is a heart patient, in the hospital waiting on test results to determine whether the recommended angiogram followed by new stents should follow.
    For breakfast they fed him eggs and sausage. I asked what the hell is that about? They told me that is the breakfast everyone receives unless we’d like him to be on a “heart healthy diet”. She asks me, “would that be better?” I say anything would be better than eggs and sausage. He is a heart patient wow. They’re recommending life threatening and kidney compromising procedures while feeding food that causes heart disease. Sorry but that is criminal if you ask me. Will be speaking with someone else there.

  18. Health care costs are out of control. Going vegan can save money, pain and suffering from disease.
    Lower your chance of high blood pressure, heart disease and cancer by going vegan. Hospitals, doctors offices and schools should be places where good nutrition is taught and provided not places that contribute to disease and obesity. It is crazy the hospitals are feeding people the very food that caused the heart disease, high blood pressure or cancer that they are treating. Every person in the hospital should receive some nutrition education before being released. Every doctor visit should be an opportunity to educate patients about how food choices impacts their health outcomes. The fact that doctors do not get nutrition training as part of their training makes no sense. Medicare and Medicaid should require nutrition education as part of patient care. Focus should be on food choices.

  19. For the past year I have been reading up on the plant based diet. Diets suggested by Dr. Gregor and colleagues like T. Colin Cambell and Dr. Mcdougall. Within a couple weeks I felt younger, slept less, and had ridiculous energy. I did the research because many people close to me have passed with cancer, and cardio vascular disease. Sure I will admit that I love cheese and burgers, and I am also a foodie. If I go eat a large meat and cheese heavy sandwich I feel like crap all day. I have symptoms suggesting a heart related issue and when I eat fresh vegetables, cut out sugar and fat, I start to feel much better in days.
    That being said my personal experience has been successful, but I can understand the general public is very uneducated on proper diet and health regimen. Keep in mind that most doctors have about 4 credit hours of actual dietary study in medical school. Unless you are food scientist you must consider that is you are going to challenge the status quo be prepared to lose funding or tenure. We have all been taught to eat like we will live forever, never once considering you are what you eat. Depending on where you live look around, observe the way people look. Look at the department store and see the amount of shelves stocked for larger people. Read a book and write down how many calories you eat, and consider not attaching emotion to food. As soon as I mention to someone I work with for example that the lunch I am watching them eat has so much fat and calories, I can see they are depressed because of their obesity. We were all raised by someone that may not have realized the food we eat is bad for us. Not to mention that it is suggested that commercial farming is the #1 cause of global warming, not your SUV or 10mpg vehicle making your social status acceptable in suburbia.
    I'm confused there are so many people in the comments that wouldn't consider Dr. Gregor or others like him doing what is the right thing to do, help and heal. If I told you this new burger joint has the best food you would consider going to check it out without question, but if I told you a plant based diet has a high probability of adding years to your life, reducing your chance of disease and many other life threatening ailments, It is met with near complete resistance.
    My suggestion is go to the website Nutritionfacts.org, do some research before condemning the science.

  20. I hate to muddy the water any further. But Dr. Klaper says that having high cholesterol is meaningless if one is already on a well planned whole food plant based diet. He says cholesterol numbers are valid only for people on an average American diet of animal products (plus the obligatory excessive amounts of added salt, oil, and sugar). If Dr. Klaper is right, then heart disease is NOT as simple as having high cholesterol. So, is Dr. Klaper right?

  21. My first step towards a carnivore diet was the vegan diet 🙂 When your health fails remember to try eating only animal products for about a month and see if your health improves.

  22. The controversy is still not over. Every other day a new study comes out declaring that cholesterol is good for you and it's best to eat meat, eggs and dairy.

  23. Can you provide any research that shows cholesterol actually causes ACVD? Most of what you show proves that LDL is necessary but not sufficient. For example, people with familial hypercholesterolemia (FH) are more likely to get ACVD, but not all, only 30% or so. Why is that? If LDL was causal they should all get it. Low LDL genetic mutations show an absence of ACVD, so you can certainly conclude that LDL is necessary, I agree with that. But sufficient? Show me. My understanding is that inflammation and/or oxidation required too. Note also that most studies on FH are done in western countries, where lifestyle interacts with the high LDL. Does anyone have access to FH studies in native populations who are not sedentary? Or who do not consume sugar?

  24. Why should the amount of cholesterol in the blood determine whether or not atherosclerosis takes place? A cholesterol level of 210 is considered high. Let's say you lower it by a third to 140. So what? Why wouldn't that still provide plenty of cholesterol to feed the plaques? Think about the reasoning involved. It is that plaque formation is a numbers game, that if you get your cholesterol low enough, that the pathological depositing of cholesterol into arterial walls won't happen, even though cholesterol is still amply present. The implication is that it's the concentration of cholesterol in the blood that determines the whole process. But, that is surely not true. I do blood tests on people who are fasting, and cholesterol rises precipitously on a fast Total cholesterol can easily rise above 300! And yet very positive changes take place during fasting, including the reversal of heart disease. I've seen some amazing things in my day, such as a person with intermittent claudication who could barely walk without getting leg pain being able to walk normally after two weeks of fasting. So, that improvement, that reversal of pathology happens while blood cholesterol is sky high! We need to be smarter than this. This is very much caveman thinking. Instead of "fire bad" it's "cholesterol bad."
