Cholesterol:
What Your Doctor
Has Six Minutes
to Explain —
and What He Cannot.
Your body produces cholesterol every single day because it cannot function without it. Your brain is 25% cholesterol. Every hormone you make starts as cholesterol. Every cell membrane you have is built from it. Then a number comes back from a routine blood test — and a prescription follows. This article is the full conversation.
A 2025 study followed 100 people with high cholesterol for one year. Those with no existing plaque developed no new plaque.
Published in JACC Advances — the Journal of the American College of Cardiology — the study isolated LDL as a single variable. The result: in people with no pre-existing plaque, high LDL did not cause plaque to form.
The researchers’ own conclusion: “Plaque begets plaque. The narrative that’s often put forth is overly simplified.”
This is not a fringe finding. This is the most prestigious cardiovascular journal in the world telling us that what we were told is not the complete picture.
The Most Essential Molecule You Were Taught to Fear
Cholesterol is not a toxin. Not a waste product. Not a mistake. Your body produces 80–85% of it in the liver because it cannot function without it. Only 15–20% comes from diet.
Every cell membrane requires cholesterol for structure, fluidity, and regulation of what passes in and out.
The brain contains ~25% of the body’s cholesterol. Primary component of myelin sheaths protecting nerve fibres. Essential for memory and serotonin function.
Testosterone, estrogen, progesterone, cortisol, DHEA — every steroid hormone begins as cholesterol. No cholesterol means no hormones.
Vitamin D is synthesised from cholesterol in the skin when exposed to sunlight. Low cholesterol impairs vitamin D production.
Converted into bile acids to emulsify dietary fats and absorb fat-soluble vitamins A, D, E, and K.
Macrophages reprogram their cholesterol metabolism in response to infection. Cholesterol rises during acute illness as a repair and defence mechanism.
“Seniors with the highest cholesterol have the best memory function. Low cholesterol is associated with depression, Parkinson’s disease, violent behaviour, and cancer mortality. This is documented in peer-reviewed literature — not fringe claims.”
How a Number Became a Disease
Nobel Prize chemist Adolf Windaus found that plaques contain six times the cholesterol of healthy arteries. The assumption: cholesterol causes plaque. The question nobody asked: is the cholesterol there because it caused the damage, or because the body sent it to repair damage caused by something else?
UC scientist John Gofman, using a newly invented centrifuge, reported that total cholesterol was “a dangerously poor predictor” of heart disease. This was the same decade as Keys’ hypothesis. It was largely ignored.
Keys proposed: dietary fat raises cholesterol, high cholesterol causes heart disease. He published data from 7 countries. He had data from 22. He selected the 7 that supported his hypothesis. The 15 that contradicted it were excluded. Keys sat on the board of the American Heart Association when the AHA officially adopted his low-fat guidelines. Sixty years of global dietary policy followed from selectively presented data.
British researcher John Yudkin argued that sugar — not fat — drove cardiovascular disease. Internal documents reveal the sugar industry funded research to discredit Yudkin and reinforce the fat-cholesterol narrative. As long as fat was blamed, sugar escaped scrutiny.
The first statin drug was approved. Statins lower LDL by blocking the mevalonate pathway in the liver. For people with existing cardiovascular disease, statins reduce the risk of heart attacks and strokes. This is real and documented. The controversy is about who else they are being given to.
Keys himself stated: “There’s no connection whatsoever between cholesterol in food and cholesterol in blood… And we’ve known that all along.” He said this at 93. The guidelines built on his hypothesis had been in place for 36 years.
A JAMA Internal Medicine analysis found that under the AHA’s updated PREVENT risk model, up to 40% fewer people would meet the criteria for statin therapy compared to current prescribing practices. The prescribing guidelines have not yet been updated to match.
Who Benefits — and the Full Picture
Statins save lives for people with existing cardiovascular disease or familial hypercholesterolaemia. That is not in dispute. The question is about healthy people who receive statins based primarily on a single LDL number from a routine check.
In the largest statin survey by the National Lipid Association, ~30% of patients reported muscle pain and weakness.
57% who reported side effects stopped the drug. Nearly 75% of primary prevention patients stop within two years.
Under the updated AHA PREVENT model, up to 40% fewer people would be statin candidates than current guidelines indicate.
The FDA requires statins to carry warnings for both increased diabetes risk and potential cognitive impairment. Official regulatory acknowledgements.
Statins block the same pathway that produces CoQ10.
Statins inhibit HMG-CoA reductase in the mevalonate pathway. This pathway produces not only cholesterol but also Coenzyme Q10 (CoQ10) — the molecule every cell requires for mitochondrial energy production.
Statins consistently reduce blood CoQ10 levels. CoQ10 deficiency produces exactly the symptoms statin users most commonly report: muscle pain, weakness, cramps, fatigue.
A meta-analysis of 12 randomised controlled trials (575 patients), published in the Journal of the American Heart Association, found CoQ10 supplementation significantly reduced all four of these muscle symptoms.
If you are on statins and experiencing muscle pain or fatigue, this is a documented mechanism — not coincidence. Discuss CoQ10 supplementation with your doctor before deciding to stop your statin.
What Is Cholesterol Actually Doing When It Is High?
A growing body of research supports this framework: cholesterol is not the cause of arterial damage. Cholesterol is the repair response to arterial damage.
Chronic inflammation — from refined carbohydrates, industrial seed oils, stress, insulin resistance, smoking — damages the arterial lining. The body dispatches LDL cholesterol to the site as part of the repair process. Cholesterol is found at plaque sites not because it caused the damage, but because it was sent to repair damage caused by something else.
It is the difference between finding firefighters at a fire and concluding that firefighters cause fires.
It is oxidised LDL — not LDL itself — that damages arteries.
When LDL is present in excessive amounts in an inflamed environment, some of it oxidises. Oxidised LDL is absorbed by macrophages that accumulate in arterial walls, forming foam cells and plaque. The oxidation is the trigger — not the LDL level alone.
What causes oxidation? Chronic inflammation, refined carbohydrates, industrial seed oils, smoking, and metabolic syndrome. The triglyceride-to-HDL ratio — a marker of insulin resistance — is a more accurate cardiovascular risk predictor than LDL alone.
An active, healthy person with high LDL, low triglycerides, good HDL, low CRP, and no existing plaque has a very different risk profile than a single number implies.
The Conversation You Are Entitled to Have
LDL in isolation is not the whole picture. This is the full picture.
- What is my triglyceride-to-HDL ratio? Below 2 is low risk. Above 4 is concerning. A more sensitive marker of metabolic health than LDL alone.
- What is my C-reactive protein (CRP)? A direct measure of systemic inflammation — the upstream cause of cardiovascular disease. Low CRP with high LDL is a very different situation from high CRP with high LDL.
- What is my fasting insulin? Insulin resistance is among the strongest predictors of cardiovascular disease. Most routine panels omit it.
- Do I have existing plaque? A coronary calcium score (CAC scan) directly measures plaque. Inexpensive, low-radiation, actual evidence rather than inference from a blood marker.
- Under the updated AHA PREVENT model, would I still qualify for statins? Up to 40% fewer people would. The prescribing guidelines have not caught up with the science.
- What can lifestyle modification achieve before we consider medication? Reducing refined carbohydrates, replacing seed oils, consistent exercise, and adequate sleep produce real lipid improvements in many people.
What Has Always Been in the Masakan
These are not treatments. They are foods that support the conditions under which cholesterol behaves appropriately — daily, as the traditional kitchen always used them.
Serai (Lemongrass): Five cups of tea daily reduced LDL by 11.1% and total cholesterol by 6.5% in a documented study. Promotes fecal excretion of cholesterol — the body eliminates it rather than a drug blocking its synthesis.

“High cholesterol causes heart disease.”
High LDL is associated with cardiovascular risk in specific populations — particularly those with existing disease or multiple risk factors. But half of heart attack patients have normal or low cholesterol. The 2025 JACC Advances study found high LDL without existing plaque did not produce new plaque. The accurate statement: oxidised LDL in an inflamed arterial environment contributes to plaque. LDL alone in an otherwise healthy person is a poor predictor.
“Eating cholesterol raises your blood cholesterol.”
The 2015 US Dietary Guidelines removed the warning against dietary cholesterol, acknowledging it has no significant effect on blood cholesterol in most people. The liver compensates automatically — eat more, produce less. Ancel Keys admitted this in 1997. Decades of advice to avoid eggs for heart health were not supported by evidence even when issued. Blood cholesterol is governed by liver function, genetics, and metabolic health — not primarily by diet.
“Saturated fat causes heart disease.”
A 2010 meta-analysis of nearly 350,000 people found no significant association between saturated fat intake and cardiovascular disease. The blanket “saturated fat is bad” directive was built primarily on Keys’ selectively presented data. The type of fat, the overall dietary context, and individual metabolic variation all matter enormously.
“Statins are dangerous and should be avoided.”
For people with existing cardiovascular disease, statins reduce the risk of heart attack and stroke. This is real. In Australia, a media programme about statin dangers caused prescriptions to drop 14,000 per week — researchers attributed 1,500–3,000 avoidable cardiac events to this over five years. The debate is about who should be prescribed statins, not whether they work for those who genuinely need them.
“HDL is always good. LDL is always bad.”
LDL and HDL are lipoprotein carriers, not cholesterol itself. Recent studies found no consistent preventive effect of high HDL. Small, dense LDL particles are more dangerous than large, buoyant ones — but a standard panel does not distinguish them. Oxidised LDL is far more relevant to plaque than LDL level alone. The triglyceride-to-HDL ratio — rarely discussed in six-minute appointments — is one of the most meaningful numbers in a basic lipid panel.
“High cholesterol always means medication.”
High LDL in isolation, in an active person with good HDL, low triglycerides, low CRP, no existing plaque, no diabetes, no hypertension, and no family history of early cardiovascular disease, is a very different situation from high LDL with multiple compounding risk factors. The updated PREVENT model would remove up to 40% of current statin candidates. Lifestyle change — reducing refined carbohydrates, replacing seed oils, exercising, sleeping well — produces real results in many people without any pharmaceutical intervention.
This article does not tell anyone to stop their medication. That is a decision for you and your doctor, based on your full clinical history. Stopping statins after a cardiac event or with significant cardiovascular disease carries documented risks.
What this article gives you is the fuller picture the six-minute appointment cannot contain. The history. The scientific debate. The documented side effects and their mechanism. The questions you are entitled to ask. The lifestyle approaches that address the upstream causes rather than the downstream number.
Read widely. Think clearly. Ask your doctor the full questions. You are entitled to that conversation.
For educational purposes only. Not medical advice. If you have existing cardiovascular disease, a history of heart attack, or familial hypercholesterolaemia, statins may be providing documented life-saving benefit.
