@lassevenho4702 5 месяцев назад

In my opinion, the original question is not set in the best possible way. The hypothesis is that saturated fat raises LDL cholesterol, which over time leads to narrowing of the arteries and eventually to terminal events. As a result, supermarkets are full of low-fat products. What if the better question is "can the amount and composition of fat being changed to reduce the incidence of heart disease". The Multiple Risk Factor Intervention Trial provides an answer to this: fat repair does not reduce cardiac events.

That’s what Dr.Attia did when he was on ketogenic diet for 3 years. But he recognized that polymorphisms among apparently-healthy individuals on ketogenic diets exist: their LDL & cholesterol count rises despite triglycerides going down. In their specific cases, saturated fat intake was put into

my only problem with this statement has nothing to do with the saturated fats. if you're eating junk, yeah maybe worry about maintenance calories. eating a low carb, primarily animal based diet, you can forget about calories.

They didn't publish it because they didn't finish it, they lost 83% of their subjects. And they didn't differentiate trans fats, because they didn't know that it was bad back then. The unsaturated fats group almost certainly had more trans fats. The video below is a good analysis. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hmU_CafaPGQ.htmlsi=gbNZ7ie0u0_hMluo

@@SpindlyScoudrel If you can show me one study where someone with elevated cholesterol levels with other concerning markers has an increased risk of cardiovascular risk I'd love to see it. But I'll save you the time it doesn't exist. Cholesterol is a co-morbidity, an extremely weak indicator of anything in isolation. I am not trying to find a way to make an unhealthy lifestyle slightly less risky. I have seen virtually no evidence that increased saturated fat in otherwise healthy people poses any threat. If you are metabolically unhealthy it is crystal clear there is highly increased risk. Peter and I do not believe in vilifying something with literally no proof amongst a healthy cohort of people.

@SpindlyScoudrel 4 месяца назад

@mikeyd7733 You're still confused with what I'm pointing out. Whether you personally believe saturated fat is good or bad doesn't matter. Do whatever you want. I'm saying Peter believes he has to have low apob to reduce his cardiovascular risk. Saturated fat above around 10% of total energy intake raises apob which Peter accepts. Why then does he think lowering apob whith diet changes, ie reducing sat fat, doesn't reduce your cardiovascular risk? Again, this isn't about what you or I believe but what Peter believes.

@svenpetrus588 5 месяцев назад

I'm quite new to this matter. Is there any guideline of how many grams of saturated fat would be too much per day(compared to total calorie intake or bodyweight or whatever). Or are there too many other factors and you kind of have to figure that out by yourself by doing bloodtests(if yes, APO-b would be the one to measure right? since Attia stated in a podcast with Huberman "I only care about APO-b")

@willnitschke 4 месяца назад

I study health topics about 10 hours a week, and have been doing so for the last 7-8 years. I've found no good evidence to be concerned about saturated fat provided that (and these are important but's...) you have poor genetics. First get a CAC score done and then a CIMT. If you flunk those tests, then get your ApoB levels tested. Of more importance, healthy weight, high protein diet, lower your carbs, exercise a lot.

Correct. LDL/APOB is a REQUIREMENT for atherosclerosis. Without it you cannot get cardiovascular disease even if you smoke, are fat and diabetic, and chronically inflamed. This issue is not remotely debatable. High consumption of saturated fat causes cardiovascular disease. Trans fats are unhealthy for the same reason saturated fat is. They raise your LDL cholesterol to unhealthy levels.

@Millard12345 4 месяца назад

He's saying saturated fat seems to have weak or no effect if the person is a healthy weight. That's not a cop out.

@donwinston 4 месяца назад

@d12345 He is wrong. It is a proven fact that a high saturated fat diet will GREATLY increase your LDL cholesterol even if you are fit and otherwise healthy. If you were unfit then of course it would have an even greater effect up to a point anyway. There is a diminishing increase in LDL cholesterol for higher and higher amounts of saturated fat consumption. The meat and dairy industry funded studies in the past and tried to use this fact to muddy the waters about saturated fat. They would compare high saturated fat diets with HIGHER saturated fat diets. Report no difference in LDL cholesterol and claim saturated fat does not raise LDL cholesterol.

@@mariad.8204 “Correlation doesn’t equal causation.” So many cholesterol denialists say this as if they know what it actually means. They actually don’t. Actually, correlation does not necessarily equal causation but it can because you can identify the causal mechanism and you can rule out alternative explanations, then an association really does become credibly causal. It’s actually ApoB. LDL-C is a predictor because all LDL have ApoB tags. So it’s a “dirtier” predictor than ApoB. But ApoB is actually what causes the arterial plaque. And this is a causal relationship. The Mendelian randomization data shows this. Lean people can and do get heart disease and can have high ApoB/LDL levels. Obese people will have more risk factors, but the idea that “I am lean and thus in good “metabolic health” like online diet gurus say is just false. Increase in ApoB/LDL is more predictive than insulin levels or anything else when it comes to heart disease caused by arterial plaque. The mathematical relationship is very strong and robust. Just as robust as is the mathematical relationship between smoking and lung diseases, in fact.

Based on the conversation, here is a summary of the key points regarding the Minnesota Coronary Experiment: - The experiment was conducted in the 1970s by Ancel Keys at the University of Minnesota to test whether replacing saturated fat with polyunsaturated fat would reduce heart attacks and strokes. - It was conducted on institutionalized patients who were randomized into a high saturated fat diet group and a high polyunsaturated fat diet group, while keeping total calories and other nutrients the same. - After the roughly 5 year study period, there was no difference in cardiovascular events between the two diet groups, even though cholesterol levels decreased more in the polyunsaturated fat group. - Keys did not publish the full results in 1973, apparently because they did not support his hypothesis that saturated fat increases heart disease risk. - In 2017, Christopher Ramsden re-analyzed the data and found hints that the polyunsaturated fat diet may have actually increased cardiovascular risk in some subgroups. - The speakers conclude that the evidence against saturated fat from studies like this is mixed overall and that saturated fat restriction may not be that important if calories are controlled.

@qigong1001 4 месяца назад

Some people in the comments suggesting lowering ApoB via reduced saturated fat is “more healthy”. Very poor analysis of using a single marker to determine health status. . ApoB is a marker for heart disease, but depending on how you do your diet, you may be worsening other risk factors such as HDL levels and cholesterol. So it’s not a direct relationship. You can optimize your ApoB , but if you did it through a diet which increases sugar that’s the worst thing you can do for your health. Or if you replace saturated fat with unsaturated fat, you may optimize your ApoB, LDL, but worsen HDL and triglycerides. Reduce calories, eat less processed food.

@willnitschke 4 месяца назад

Exactly. You have to look at the big picture, and not just focus on one or a few bio-markers. Hypothetically what is the point of reducing ApoB if it drops your risk of all cause by, say, 10%, if it prevents you from making other life style changes which increase your risk by 20% ?

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.

The pro-saturated fat model is that LDL rises with saturated fat intake BECAUSE LDL built on saturated fatty acids is not as prone to forming oxidized and glycosylated species that are the primary instigators of endothelial injury leading to CHD. The body allows higher LDL when it's built on saturated fats because it can't form oxidative radicals and is much harder to glycosylate than PUFAs. As a result, LDL elevations due to saturated fat intake DON'T correlate much less cause higher CHD. (That's the claim and it does hold up in certain parts at least).

@stellasternchen 3 месяца назад

Long term high LDL-C levels have shown to increase cardiovascular events and death. Sorry but this is a fact. LDL-C might not be the best predictor though, as metabolic disease increases small LDL particles low in cholesterol, high in triglycerides and decreases large, as well as increses small HDL particles low in cholesterol and high in triglycerides and decreases HDL-C. So many obese people do not show the classic lipid risk profile. But a state of obesity is pathologic, not normal, and a risk factor for itself. It has nothing to do with PUFA, on the contrary, omega 3 has been shown in several studies lowering CVD risk.

@mertonhirsch4734 3 месяца назад

@@stellasternchen See the Omega-3 paradox. My wife is a cardiologist and Omega-3 reduces risk, but only up to about 4% of daily maintenance calories. At that point risk of heart attack begins to rise. Anyway, I am only presenting the pro-saturated fat model, or mechanistic conjecture. The model is that LDL is only a risk factor when it is oxidized and glycosylated, and that the risk does not rise when LDL is elevated but not oxidized or glycosylated at high rates. That's the model. There are even suggestions that the liver allows higher LDL levels when saturated fat is higher because it doesn't raise oxidative and glycosylation stress, acting as a feedback mechanism. You can show that saturated fat raises LDL and that people with LDL are at higher risk, but you can not prove that people with higher LDL are at risk independent of the glycosylation and oxidized state of the LDL particles.
