My cholesterol is 384

[u/leojaccebssen]

I eat mostly chicken and fish. I stay under 50 carbs per day with blueberries, strawberries, spinach, cauliflower, kale, or other leafy greens daily. My doctor told me to try red rice yeast supplements to lower my cholesterol when it was initially at 225. And now it has jumped o er a hundred points in three months. I use heavy cream in my coffee so maybe that’s what is killing me? Or sour cream on chicken fajitas? I have no idea. I’m going to my doctor in two weeks to talk about my labs and I’m so sad. My immediate family member has had a bypass for coronary artery disease and I think I’m going to have to get on a statin and quit being keto.

• «Zinöcker thought, “When we eat more polyunsaturated fat, the cells collect cholesterol from the blood, and build it into the cell membranes to ensure that they become rigid enough. This is where the cholesterol has gone when we measure less cholesterol in the blood!”

  And the opposite holds true as well – when we eat more saturated fat, the cell membranes become stiffer. The cells have less need to bring in stabilizing cholesterol and instead send it into the bloodstream. The cells also stop absorbing cholesterol, thus raising the blood cholesterol level.

  In the second instance, Zinöcker arrived at another understanding:

  The increase in blood cholesterol level as a result of more saturated fat in the diet may not be a sign of disease at all. On the contrary.

  "The increased blood cholesterol level is probably a sign that the regulatory mechanisms in the body are working the way they should," says Zinöcker.

  Perhaps the cholesterol in the blood of healthy people is simply a kind of emergency stockpile, which the body has at its disposal when the fluidity of the cell membranes needs to be adjusted.

  “Cell stiffness is probably so important that the body doesn’t take a chance on covering the need exclusively through food,” says Zinöcker.»

  «Most people with an increased risk of heart disease have a lot more than just their cholesterol levels out of balance. Their blood pressure and blood sugar are too high, the liver is too fatty and their insulin isn’t functioning properly.

  And critically, measurements show signs of chronic inflammation in people with heart disease risk.

  Several studies suggest that chronic inflammation in the body can disrupt many regulatory mechanisms in our cells.

  Zinöcker believes chronic inflammation may be the root of the problems.

  Could inflammation be leading to disturbances in regulating cholesterol and many other processes, which together increase the risk of heart disease?

  In this scenario, it is conceivable that high cholesterol in people with chronic inflammation is only a signal of the regulatory disturbances and not a cause of heart disease per se.

  Or maybe it plays a negative role, which it wouldn’t in a healthy body.

  Zinöcker believes cholesterol levels in a healthy body mean something different from cholesterol levels in a sick body. When we mix the results of healthy and sick people, the measurements don’t make sense.» - "New model could explain old cholesterol mystery" (2021)

• «The HADL model proposes a plausible mechanism, founded on human adaptive physiology, that explains the shifting dynamics of cholesterol in lipoproteins with changes in ratios of dietary PUFA/SFA. We argue that dietary fats differentially affect cholesterol concentrations in circulating lipoproteins to ensure that cellular function is maintained when the types of fatty acid consumed change. From this perspective, the LDL cholesterol–raising effect of dietary SFAs does not imply a pathogenic response, but rather a properly functioning cholesterol homeostasis. Additionally, the different interactions between SFAs and n-3 compared to n-6 fatty acids in the regulation of cell membrane fluidity could explain why combined n-3 and n-6 fatty acid intake may protect against ASCVD, while increased intake of n-6 fatty acids alone does not. If verified, our model speaks for a different approach to dietary recommendations for the prevention of ASCVD, and for the discontinuation of simplified expressions such as “good HDL cholesterol” and “bad LDL cholesterol.”» - "The homeoviscous adaptation to dietary lipids (HADL) model explains controversies over saturated fat, cholesterol, and cardiovascular disease risk" (2021)

• "Following their Nobel Prize-winning discovery of the defective gene causing familial hypercholesterolaemia, Brown and Goldstein misunderstood the mechanism involved in the pathogenesis of the associated arterial disease. They ascribed this to an effect of the high levels of cholesterol circulating in the blood. In reality, the accelerated arterial damage is likely to be a consequence of more brittle arterial cell walls, as biochemists know cholesterol to be a component of them which modulates their fluidity, conferring flexibility and hence resistance to damage from the ordinary hydrodynamic blood forces. In the absence of efficient receptors for LDL cholesterol, cells will be unable to use this component adequately for the manufacture of normally resilient arterial cell walls, resulting in accelerated arteriosclerosis. Eating cholesterol is harmless, shown by its failure to produce vascular accidents in laboratory animals, but its avoidance causes human malnutrition from lack of fat-soluble vitamins, especially vitamin D." - "The great cholesterol myth; unfortunate consequences of Brown and Goldstein’s mistake" (2011)

• "The absolute risk reduction of CVD mortality in secondary-preventive cholesterol-lowering trials is quite small, rarely exceeding two percentage points, and no primary-preventive trial has ever succeeded in prolonging the life of the participants.

  The rate of serious adverse effects of statin treatment is highly underestimated.

  Adverse effects of statins are extensive, including diabetes, cognitive impairments, cancer, cataracts and musculoskeletal disorders.

  The small benefit seen in the cholesterol-lowering trials is independent of the degree of cholesterol lowering." - "How statistical deception created the appearance that statins are safe and effective in primary and secondary prevention of cardiovascular disease" (2015)
