There are two types of cholesterol: High-density and low-density lipoprotein, aka HDL and LDL, but how they affect your heart and your longevity is the subject of ongoing controversy.
- Cholesterol, the soft, waxy substance found in every cell in your body, is used to produce several of your body’s vital functions, including hormones and vitamin D. High cholesterol is now recognized for its link to longer life
- Faulty science says your total cholesterol is not a gauge of your heart disease risk, because when your levels are measured, elevated levels called triglycerides are also taken into account
- Found in every cell of your body, cholesterol is used to produce several of your body’s vital functions, including those that involve hormones and vitamin D
- Studies show a contrary or inverse link between all-cause mortality and total cholesterol levels; in other words, mortality is highest when your cholesterol is low, without exception
- Considering the false information on cholesterol, continued prescriptions for statins, and the potentially devastating side effects they cause, it’s clear why researchers are calling for a paradigm shift in the way cholesterol is treated
Taking a global view of what cholesterol is and how it affects your body is a smarter way to approach it than the simple "cholesterol kills" narrative that's been the drum beat for so many years.
Cholesterol, the soft, waxy substance found in every cell in your body, is used to produce several of your body's vital functions, including those that involve hormones and vitamin D. About 75% of it is made by your liver and the remainder is derived from the foods you eat; 25% is in your brain.
There are two types: High-density is the first. It is also known as HDL, or the “good” kind that keeps cholesterol away from your arteries and removes it from your arteries. The second type is low density lipoprotein, or LDL. LDL is the “bad” kind that can build up in your arteries, form plaque that narrows your arteries and form a clot. This can then make its way to your heart or brain and cause either a heart attack or stroke.
"So far, both cardiologists and [physicians] have focused mostly on reducing LDL cholesterol, but in the future, the focus will also be on reducing triglycerides and remnant cholesterol."
Does It Matter What Kills You?In a commentary posted on Mission.org, a rhetorical question is presented: With all the ways you can die, does it really matter what kills you? On one hand, "If you're dead, you're dead, no matter from what," so it seems silly to "focus on changing something that lowers the risk of death from one cause only to raise that risk from another."
It’s an astute observation when you read studies showing conclusively that cholesterol has very little to do with heart disease. Even more importantly, cholesterol is crucial for your health. If it’s too low, then eventually, your hormones, disease risk, cell signaling pathways, and yes, your heart, will suffer. In fact, new research shows that a too-low LDL level could put you at higher risk for a stroke.
"Previously, the Dietary Guidelines for Americans recommended that cholesterol intake be limited to no more than 300 mg/day.
Chastising the USDA for remaining "silent on fat," Harvard Health says this "could steer consumers toward the type of low-fat, high-carbohydrate diet that makes it harder to control weight and worsens blood cholesterol profiles."
It’s no wonder people are confused about where cholesterol fits in your diet, when major health agencies send one message to the public and the government sends a completely different one in their dietary guidelines.
"Our data accord with previous findings of increased mortality in elderly people with low serum cholesterol, and show that long-term persistence of low cholesterol concentration actually increases risk of death."The narrative challenges those who insist that eating foods that contain fat of any kind — saturated fats and trans fats alike — are harmful. Many who make this claim also maintain that "Saturated fat is a bad fat because it raises your LDL level more than anything else in your diet." However, as explained in the Mission.org article:
"While total cholesterol is a poor if not utterly worthless risk marker for heart disease, doctors have focused on it to the exclusion of how it might affect other causes of death. It does you little good to save yourself from heart disease if it means that you increase your risk of death from cancer. All-cause mortality — death from anything — is the most appropriate measure to use when looking at risk factors."
The Best Measure for Risk Factors"Death from anything" may be a clearer term for the one so often used in clinical settings: All-cause mortality. Either way, as quoted by the following study, that's what the latest research says is the best measure for the factors that increase the risk of what eventually and most likely will take someone's life.
"Overall, an inverse trend is found between all-cause mortality and total (or low density lipoprotein [LDL]) cholesterol levels: mortality is highest in the lowest cholesterol group without exception. If limited to elderly people, this trend is universal. As discussed in Section 2, elderly people with the highest cholesterol levels have the highest survival rates irrespective of where they live in the world …
The study adjusted for several heart risk factors like smoking, high blood pressure and a history of diabetes melllitus. Participants were placed in groups depending on whether their cholesterol levels were low, medium or high, and those with the highest cholesterol levels were found to have the lowest death rates.
The title of the BMJ review reveals the outcome — there was a "lack of an association or an inverse association between low-density-lipoprotein cholesterol and mortality in the elderly."
"Our review provides the basis for more research about the cause of atherosclerosis and (cardiovascular disease) and also for a re-evaluation of the guidelines for cardiovascular prevention, in particular because the benefits from statin treatment have been exaggerated."One of the first studies published with information suggesting that high cholesterol is not as heart-damaging as once thought was the Honolulu Heart Program, offering further evidence that higher cholesterol levels may be heart protective. The authors concluded by questioning whether there is "scientific justification for attempts to lower cholesterol to concentrations below 4-65 mmol/L in elderly people," adding that "prudence dictates a more conservative approach in this age group."
Can High Cholesterol Really Be Heart Protective?Perhaps the question that would get to the point quicker is to ask why the Japanese study infers that people with low versus high cholesterol die sooner? The Mission offers referenced studies that show a few factors that could be weighing in:
- Cholesterol may protect against infections and atherosclerosis, as "the many observations that conflict with the LDL receptor hypothesis, may be explained by the idea that high serum cholesterol and/or high LDL is protective against infection and atherosclerosis."
- Cholesterol may protect against cancer, although in previous cases where low cholesterol was linked to cancer, exclusions were made to tip the scales, such as excluding possible prior drug treatment, namely clofibrate, a popular cholesterol-lowering drug before statins, by subjects — leaving the question open as to whether it was the low cholesterol that caused the cancer, or the drug treatments that contributed to it.
- Low cholesterol (180 mg/dL and lower) and violence in psychiatric patients have been linked. When patients in a long-term psychiatric hospital with a history of seclusion or restraints were compared with other patients, there was a "highly significant and strong association between lower cholesterol levels and violent behavior." The authors did caution, however, that cholesterol levels should not be used to predict violence.
- There's also an association between low cholesterol and suicide dating back more than a decade, as researchers found that people in the lowest quartile of cholesterol concentration had more than six times the suicide rates than those in the highest quartile. It should be noted that at least one study in Japan determined that high cholesterol and suicide were connected.But, in fact, numerous recent studies have corroborated the earlier ones connecting low cholesterol to suicide, with various findings: For example, one found that low triglycerides, reduced BMI and waist circumference, specifically, but not total cholesterol, were connected to a higher risk of suicide; while a 2019 study found that "low cholesterol is associated with aggression in suicide attempters."
So What About Statins?Significantly, the authors of an Annals of Nutrition & Metabolism study didn't hold back when drawing conclusions regarding why the cholesterol conundrum has gone on so long when the evidence is so clear: "For the side defending this so-called cholesterol theory, the amount of money at stake is too much to lose the fight."
The Annals of Nutrition & Metabolism study's introduction mentions a medical practitioner who advocated statins to his patients to drive down cholesterol until he read the Scandinavian Simvastatin Survival Study, in which 4,444 patients with different types of heart disease were given simvastatin — which is touted to be a safe, long-term treatment to improve survival in cardiovascular heart disease patients.
"Our search for falsifications of the cholesterol hypothesis confirms that … the conclusions of the authors of the three reviews are based on misleading statistics, exclusion of unsuccessful trials and by ignoring numerous contradictory observations."Drugs.com contributors state that the 35 million people on statins often experience myriad side effects. Liver damage, for instance, is said to be "rare," implying that ongoing liver tests while taking statins likely aren't necessary. Some doctors, however, say you'll need a baseline liver function test beforehand. The most common side effects of statins are:
- Headaches, muscle pain, lower back or side pain
- Nasal congestion or stuffiness, or a runny nose
- Difficulty sleeping
"Men seem to be more sensitive to low cholesterol levels as the association between low cholesterol levels and aggression is found mostly in men," the authors said. "… Lowering cholesterol levels with statins brings about several changes in the serotonergic system, nerve cell membrane microviscosity and behaviour, and needs to be done with precaution in susceptible individuals.
More Studies and Reviews on Statin UseRather than pointing patients in the direction of finding dietary solutions, including eating both the whites and the yolks when having eggs, and ditching processed vegetable oils in favor of healthy cooking oils like coconut oil, olive oil and avocado oil, Harvard Health Medical School updated an article on how to “manage” muscle pain from taking statins, perpetuating the cholesterol myth. They stated:
"If you're not taking a statin now, you may well be soon. These medications are commonly prescribed to lower 'bad' LDL cholesterol and have been shown to reduce the risk of heart attack, stroke, and death.
As if that weren't enough, experts say statins may impair your memory and cause amnesia, a possibility real enough to call for a warning on the labels of prescriptions. Statin use may precipitate a higher risk of developing cataracts and it "significantly" increases the likelihood of raising the fasting glucose levels of non-diabetics, as well as inducing high blood sugar.
In another review of the adverse effects of statins, it was noted that "an array of additional risk factors for statin AEs [adverse events] are those that amplify (or reflect) mitochondrial or metabolic vulnerability, such as metabolic syndrome factors, thyroid disease, and genetic mutations linked to mitochondrial dysfunction."
"This, we believe, marks the starting point of a paradigm shift in not only how we understand the role cholesterol plays in health, but also how we provide cholesterol treatment …
