Few lines on a blood test set off alarm bells quite like elevated cholesterol. I see it constantly in clinic — someone arrives genuinely frightened, convinced they've done something terribly wrong and that every food they enjoy is now off the table. I understand the worry personally: I sit just over the borderline for high cholesterol myself, and it runs in my family. So let's take the fear out of it and replace it with some understanding.
What cholesterol actually is — and why your body makes it
Cholesterol is a sterol, which is a type of fat. Yes, it's present in food. But here's the thing most people don't realise: your own liver manufactures it, and it builds it from a molecule your body creates when it metabolises food — any food. Carbohydrates, fats and protein all break down to the same basic building block that the liver then uses to make cholesterol. So nobody is exempt by cutting out one food group.
Your liver wouldn't be going to that trouble if cholesterol weren't useful. It is the raw material for your sex hormones — testosterone, oestrogen, progesterone all share a cholesterol backbone. It's the precursor your body needs to make vitamin D. It's used to make bile, which is how you absorb fats in the first place. Every single cell membrane in your body contains cholesterol, and it's what keeps that membrane fluid enough to let nutrients in and waste out. Without it you'd have rigid, poorly nourished, increasingly toxic cells.
And it's crucial in your brain. A commonly cited figure puts around 20 to 25 per cent of the body's cholesterol in the brain, where most of it goes into building myelin — the insulating sheath around the axons that carry every electrical impulse of thought and movement. Your neurons synthesise cholesterol themselves because they need it that badly.
The myths worth dropping
Myth: foods containing cholesterol are the enemy. I've had clients tell me they've given up prawns. Food is not the major source of your blood cholesterol — your liver is. That said, there is a nuance: if you're eating a very high-fat diet, including some ketogenic approaches, you may well see your levels rise. I've seen it in clients. And eating a lot of fat usually means eating less fibre, which matters enormously for the reason I'll come to.
Myth: high cholesterol is a man's problem. It isn't. High cholesterol affects women too, and so does heart disease. If anything, men may carry more of the surrounding risk factors on average — but nobody should assume they're exempt on the basis of sex.
Myth: cholesterol itself is the disease. One view I've encountered from prominent cardiologists, and which I find clarifying, is that what deserves equal attention is the cluster of risk factors that tend to travel alongside high cholesterol. Here's the mechanism in plain terms: LDL — low-density lipoprotein — is the form that does repair work on damaged artery walls. If the arteries are being damaged, by inflammation or by sustained high blood pressure, and there's a lot of LDL circulating, it floods the damaged site and builds up. That accumulation is atherosclerosis, and a clogged artery is how a heart attack happens. So the number matters — but so does whether your arteries are being damaged in the first place.
The risk factors you can actually do something about
The familiar list: excessive alcohol, smoking, recreational drugs, a sedentary lifestyle, a highly inflammatory diet heavy in processed food, trans fats, fried food and sugar — and chronic, unmanaged stress.
Notice what most of those have in common. They all load up the liver. When the liver is flat out processing alcohol, caffeine and the by-products of a poor diet, it has fewer resources for everything else it's meant to be doing — including making hormones, producing bile and helping regulate cholesterol. Think about the common pattern of caffeine all day to get going and alcohol at night to come down: that's a liver working two shifts.
Stress belongs on this list properly, not as an afterthought. Sustained emotional pressure raises blood pressure, and prolonged high blood pressure is what damages artery walls in the first place.
What to eat: fibre is the quiet hero
Here's the connection that makes everything click. Your body uses cholesterol to make bile. Bile binds to fibre in your gut, and that fibre carries it out of the body when you go to the toilet. Your body then has to use more cholesterol to make more bile. Eating fibre is, quite literally, one of the most direct ways to encourage your body to use up circulating cholesterol.
And where does fibre come from? Largely carbohydrates — the food group people cut first. Oats, barley, legumes, whole grains, vegetables and fruit. Specific standouts worth putting on your plate: oats or barley porridge to start the day, soy, okra, eggplant.
Beyond fibre, think about the cofactors. Metabolising cholesterol relies on nutrients including vitamin C, B3, B6 and zinc. Vitamin C comes from citrus, kiwifruit, berries and leafy greens like kale. Zinc is bound to protein, so an under-protein diet can leave you short. Oily fish is a particularly useful protein choice here. So the practical instruction is boringly familiar and genuinely effective: a wide variety of plants and colours, adequate protein at each meal, oily fish regularly, plenty of water, less fried and heavily processed food — and moderation rather than elimination of any one group.
Movement, sleep and emotional regulation
On exercise, the research supports both high-intensity interval work and resistance training for improving the balance between HDL and LDL — HDL being the form that transports cholesterol back to the liver for processing, which is why a higher HDL relative to LDL is the pattern we want. But plain movement counts enormously too. Thirty minutes a day, and you can break it into three ten-minute pieces around meals. Get off the bus a stop early. Take the stairs. I do a lot of walk-and-talk meetings and they genuinely lift my daily movement.
Sleep belongs in a cholesterol conversation because the liver does its repair and regeneration overnight. An organ that never gets a proper recovery window won't do any of its jobs well.
And then emotions. If you're using alcohol to cope, the more useful question than "how do I drink less" is "what am I coping with?" In my experience, people reach for an escape when life feels unfulfilling — and the most durable fix is living in line with your own values rather than someone else's. One practical tool I use constantly: when you're caught in a resentment, ask yourself what the benefits of the situation might be, and keep asking until the emotional charge settles. If something looks entirely positive, ask what you're not seeing. Balanced perspectives calm the emotional centre of the brain, and calmer emotions mean steadier blood pressure. Traditional Chinese medicine has long linked anger with impaired liver function — I offer that as a framework rather than a proven mechanism, but the stress-to-blood-pressure-to-artery pathway stands on its own.
A word on statins
I want to be unambiguous here, because I've heard this framed badly. Statins are extensively researched and the overall evidence supports them, including long term, for reducing cardiovascular events. For many people — particularly with a strong family history, an inherited cholesterol condition, or existing heart disease — medication is clinically necessary regardless of how well they eat and move. Everything in this article is designed to work alongside your doctor's advice, not instead of it. Don't stop or skip a prescribed medication on the strength of a blog post. Take the medical advice, and reduce the risk factors as well. That's teamwork, and it's how you get the best outcome.
Key takeaways
- Cholesterol isn't the villain — your body makes it deliberately for hormones, vitamin D, bile, cell membranes and brain myelin.
- Food high in cholesterol isn't the main driver of your blood levels; your liver is. But a very high-fat, low-fibre diet can push levels up.
- High cholesterol matters most alongside artery damage from inflammation and sustained high blood pressure — so address both.
- Eat more fibre. It binds bile and carries it out, prompting your body to use up more cholesterol.
- Reduce the liver's load: less alcohol, less heavily processed and fried food, and don't run on caffeine-then-alcohol cycles.
- Combine resistance training and higher-intensity work with everyday incidental movement — thirty minutes, split up if needed.
- Treat stress and emotional regulation as cardiovascular care, not a nice-to-have.
- High cholesterol is not a men-only issue, and statins are evidence-based medicine — work with your doctor, not around them.
What I hope you take from this is a shift from alarm to agency. Cholesterol isn't something to eliminate; it's something your body is trying to regulate, and your job is to make that job easier. That's exactly the holistic approach I take at me&my wellness — food, movement, sleep, stress and emotional wellbeing are not separate departments. The liver that processes your cholesterol is the same liver dealing with your wine, your stress hormones and your broken sleep. Support the whole system and the numbers tend to follow.
