Cholesterol
1-Minute Read
Cholesterol is not simply “good” or “bad” — it is an essential fat your body needs for cell membranes, hormones and vitamin D. What matters is the balance and the bigger picture, not one number in isolation.
- A lipid profile measures total cholesterol, LDL, HDL and triglycerides — but your overall cardiovascular risk matters more than any single figure.
- Australia’s 2023 CVD risk guideline shifted the focus to absolute (whole-person) risk, with lifestyle as the foundation of management.
- Dietary patterns rich in soluble fibre, plant sterols, plant proteins and nuts have been shown in trials to meaningfully lower LDL.
- Naturopathic care may support healthy lipids by addressing diet, the gut, inflammation, stress and movement — alongside (never instead of) your GP’s care.
Telehealth consultations Australia-wide — no travel required.
Cholesterol is one of the most misunderstood words in health. For many people it is frightening — a single test result can feel like a verdict. Yet the accurate picture is more nuanced: cholesterol is a substance every cell in your body depends on, and roughly three-quarters of it is made by your own liver, not eaten. This article explains what cholesterol actually is, how it is assessed, what genuinely drives cardiovascular risk, and how an evidence-informed naturopathic approach may support healthy lipids alongside your medical care.

What Is Cholesterol — and Why Do We Need It?
Cholesterol is a soft, waxy fat found in every cell of your body. Far from being purely harmful, it is essential: it helps build cell membranes, is the raw material for steroid hormones (including oestrogen, testosterone and cortisol), supports the production of vitamin D and bile acids for digesting fats, and plays a role in healthy brain and nerve function. Because it is so important, your body makes most of it internally — which is why cholesterol levels do not always fall simply by removing cholesterol from the diet.
Cholesterol travels through the blood packaged inside particles called lipoproteins. The main types measured on a standard lipid profile are:
| Marker | What it is |
|---|---|
| HDL (high-density lipoprotein) | Often called the “protective” fraction; helps carry excess cholesterol away from artery walls back to the liver. Generally, higher is better. |
| LDL (low-density lipoprotein) | The main particle that can contribute to plaque build-up in artery walls when elevated — the primary target for lowering. Generally, lower is better. |
| Triglycerides | A storage fat used for energy. Raised levels are linked with refined carbohydrate and alcohol intake, excess weight and insulin resistance. |
| Lipoprotein(a) — Lp(a) | A largely inherited particle that can meaningfully raise cardiovascular risk. It is not part of a routine panel but is worth discussing with your GP, particularly with a strong family history. |
Total Cholesterol Is Not the Whole Story
For decades, a single “total cholesterol” figure was treated as the headline result. Modern practice takes a broader view. Two people can have identical total cholesterol yet very different cardiovascular risk, because what matters is the balance between particles (for example, the ratio of total cholesterol to HDL) and the rest of the risk picture — blood pressure, blood glucose, smoking status, family history, kidney function and age.
This is the thinking behind Australia’s 2023 Guideline for Assessing and Managing Cardiovascular Disease Risk (Nelson et al., Medical Journal of Australia, 2024), which moved away from treating isolated numbers and toward calculating a person’s absolute cardiovascular risk using a validated calculator. The guideline is clear that healthy lifestyle change is the foundation of management for most people, with medication reserved for those whose overall risk is high enough to clearly benefit.
Don’t judge your heart health on one line of a blood test. The most useful question is not “is my cholesterol high?” but “what is my overall cardiovascular risk, and what is driving it?” That is a conversation to have with your GP — and a picture naturopathic care can help you improve.
Understanding Your Results
The general Australian reference ranges below are a guide only. Your personal targets — especially for LDL — depend on your overall cardiovascular risk, so an “acceptable” number for one person may warrant action in another. Always interpret results with your GP.
| Marker | General guide (mmol/L) | Notes |
|---|---|---|
| Total cholesterol | Below ~5.5 | A screening figure — interpret alongside HDL, LDL & risk |
| LDL cholesterol | Lower is generally better; targets are individualised | Higher-risk individuals are given lower targets |
| HDL cholesterol | Above ~1.0 (higher is protective) | Supported by activity, healthy fats & not smoking |
| Triglycerides | Below ~2.0 | Responsive to reducing sugar, refined carbs & alcohol |
Cholesterol, Inflammation & the Artery Wall
A key insight from cardiovascular research is that plaque formation is not driven by cholesterol alone — it involves injury and inflammation of the artery wall. Where the arterial lining is damaged (by factors such as smoking, high blood pressure, high blood sugar and oxidative stress), an inflammatory repair process begins, and LDL particles — particularly when oxidised — can become trapped and contribute to plaque.
This matters for a naturopathic approach because it widens the focus. Rather than treating a number in isolation, the aim is to improve the underlying terrain: lowering inflammation and oxidative stress, improving blood sugar and metabolic health, and reducing the factors that damage arteries in the first place. You can read more in our related article on oxidative stress.
What Contributes to Unhealthy Cholesterol?
Lipid levels are shaped by a combination of modifiable and non-modifiable factors:
- Diet — high intakes of refined carbohydrates, added sugars, ultra-processed foods and certain saturated and trans fats
- Metabolic health — insulin resistance, excess abdominal weight and raised blood sugar, which particularly affect triglycerides and HDL
- Physical inactivity — sedentary patterns are associated with lower HDL and higher triglycerides
- Chronic inflammation and oxidative stress — which affect both lipids and the artery wall
- Chronic stress and poor sleep — which influence metabolism and lipid regulation
- Alcohol and smoking — both adversely affect the lipid and cardiovascular picture
- Genetics and family history — including inherited high cholesterol and raised Lp(a), which are not lifestyle-driven and need medical management
Conventional Management
Naturopathic care is best understood within the broader medical framework. Depending on your absolute cardiovascular risk, your GP may recommend lifestyle change alone, or lifestyle change together with lipid-modifying medication. For people at genuinely high risk — for example, those with established heart disease, diabetes, or very high cholesterol — medication is well evidenced to reduce cardiovascular events, and should not be dismissed.
Naturopathic support is designed to work alongside this care — not to replace prescribed medication or discourage appropriate treatment. If you are taking, or considering, lipid-modifying medication, that decision belongs with your GP; a naturopath can help you support your overall health and address contributing lifestyle factors in parallel.
Medication and lifestyle are not an either/or choice. For many people the most effective path combines appropriate medical management of risk with sustained changes to diet, movement and metabolic health — which is exactly where naturopathic care can add value.
Naturopathic Support for Healthy Cholesterol
Naturopathic medicine takes an integrative, whole-person view. Rather than targeting a single number, care is directed at the underlying drivers — diet, metabolic health, inflammation, gut function, stress and movement — with the aim of supporting a healthier lipid profile and cardiovascular terrain over time. All plans are individually tailored after a thorough assessment.
Therapeutic Nutrition & Cholesterol-Lowering Foods
One of the best-evidenced dietary strategies for lipids is a combination of specific plant foods — sometimes studied together as the “portfolio” dietary pattern. Controlled trials (building on the work of Jenkins and colleagues, with more recent syntheses such as Chiavaroli et al.) show that combining these foods can produce meaningful reductions in LDL, and cohort research (Glenn et al., Circulation, 2023) links closer adherence to lower cardiovascular risk. Core elements include:
- Soluble (viscous) fibre — from oats, barley, legumes, psyllium and many fruits and vegetables; binds bile acids in the gut so the liver draws cholesterol from the blood to replace them
- Plant sterols — naturally present in nuts, seeds, vegetables and legumes; compete with cholesterol for absorption in the intestine
- Plant proteins — legumes and soy foods in place of some animal protein
- Nuts — which provide unsaturated fats and bioactive compounds that support healthy lipid metabolism
- A Mediterranean-style pattern — rich in vegetables, olive oil, oily fish and whole foods, and consistently associated with cardiovascular benefit
- Reducing refined carbohydrates, added sugars, ultra-processed foods and excess alcohol — key drivers of raised triglycerides
Herbal Medicine
Herbal medicine is selected individually based on your lipid pattern, metabolic health and overall picture. General categories that may be drawn upon include:
- Lipid-modulating herbs — traditionally used and researched for supporting healthy cholesterol metabolism
- Antioxidant and anti-inflammatory herbs — to support the artery wall and reduce oxidative burden
- Liver-supportive herbs — to support the organ central to cholesterol and bile metabolism
- Circulatory and metabolic-support herbs — to support broader cardiovascular health
Movement, Weight, Stress & Sleep
Regular physical activity is one of the most reliable ways to support HDL and lower triglycerides, and it improves insulin sensitivity and inflammation at the same time. A realistic, sustainable routine — such as brisk walking, swimming or cycling most days, building gradually — tends to outperform short bursts of intense effort that are hard to maintain. Supporting a healthy weight, prioritising sleep, and managing chronic stress all further influence the metabolic environment in which your lipids sit.
Naturopathic support does not treat cholesterol in isolation. It works to improve the underlying diet, metabolic and inflammatory picture, support gut and liver function, and complement — never replace — your conventional medical care.
Working With Your Medical Team
Cholesterol care is most effective when naturopathic and conventional care are coordinated. We encourage open communication between your naturopath and GP, and we ask that you keep your GP informed before starting any new herbal medicine or supplement — particularly if you take prescribed medication. Regular monitoring of your lipids through your GP lets everyone see how your plan is progressing.
