I've Been Told My Cholesterol Is High. Now What? A Nutritional Therapist's Guide

First: Take a Breath

Being told your cholesterol is elevated doesn't automatically mean you're heading for a heart attack. Cholesterol is a naturally occurring substance in the body, it's essential for making hormones, vitamin D and the structural walls of every cell. The picture is far more nuanced than a single number suggests.

Understanding what your results actually mean is the first and most important step.

What Do the Different Cholesterol Numbers Mean?

Your cholesterol panel typically includes several measurements, and they don't all tell the same story:

• Total cholesterol - the overall amount in your blood. A useful starting point, but not the whole picture.

• LDL ('bad' cholesterol) - often the number that triggers concern. LDL carries cholesterol to the cells, but in excess it can contribute to plaque buildup in the arteries. However, not all LDL is equally problematic, particle size matters enormously, something a standard NHS test won't show you.

• HDL ('good' cholesterol) - this carries cholesterol away from the arteries and back to the liver. Higher is generally better. Low HDL is often a more significant risk factor than high LDL alone.

• Triglycerides - fats circulating in the blood, closely linked to diet (particularly refined carbohydrates and alcohol). Elevated triglycerides alongside low HDL is a combination worth taking seriously.

The Myths Worth Debunking

One of the most persistent myths in nutrition is that dietary fat and in particular, dietary cholesterol, is the main driver of high blood cholesterol. For most people, this simply isn't the case.

Eggs are the classic example. Decades of advice told us to limit eggs because of their cholesterol content. The current evidence doesn't support this for most people. For the majority, dietary cholesterol has a relatively modest impact on blood cholesterol compared to other factors.

What does have a significant impact? Refined carbohydrates and sugar (which drive up triglycerides), trans fats (thankfully now largely removed from the food supply), excess saturated fat from ultra-processed foods and critically, factors like stress, sleep quality, thyroid function and genetics.

This is why a personalised approach matters. The dietary changes that will move the needle for you depend on what's actually driving your elevated levels.

What Nutrition Can Do (And It's More Than You Might Think)

The good news is that diet and lifestyle interventions can make a meaningful difference to cholesterol levels, often more than people expect. Here's what the evidence supports:

• Increasing soluble fibre - found in oats, legumes, flaxseed and vegetables. Soluble fibre binds to cholesterol in the digestive tract and helps remove it from the body.

• Including more omega-3 rich foods - oily fish, walnuts and flaxseeds support healthy triglyceride levels and reduce inflammation.

• Choosing unsaturated fats - olive oil, avocado, nuts and seeds over processed vegetable oils and trans fats.

• Reducing ultra-processed foods - not just for their fat content, but for their sugar, refined carbohydrate and additive load.

• Supporting your liver - the liver produces around 80% of the body's cholesterol and plays a central role in cholesterol metabolism. Bitter greens, cruciferous vegetables and adequate hydration all support liver function.

• Managing blood sugar balance - insulin resistance is closely linked to elevated triglycerides and low HDL. Balancing meals with protein, fat and fibre at each sitting can make a real difference.

Why a Personalised Plan Gets Better Results

Generic 'low-fat diet' advice has been the standard response to high cholesterol for decades and the evidence for its effectiveness, at a population level, is underwhelming. The reason is simple: one size does not fit all.

When I work with clients on cardiovascular health, I look at the full picture: your specific numbers and ratios, your family history, your current diet, your stress levels, your sleep, any relevant medications or health conditions and where appropriate, advanced testing to look at inflammation markers, homocysteine, and LDL particle size.

From there, we build a practical, realistic plan that works with your life. Small, sustainable changes that you can actually maintain, not a restrictive regime that lasts three weeks.

When to Seek Further Support

Medication and nutrition can work together to support cardiovascular health. As a registered nutritional therapist, I work alongside GPs and other healthcare professionals to help clients make sustainable, evidence-based dietary and lifestyle changes that complement their medical care. If you have concerns about your cholesterol or have been prescribed medication, it's important to discuss these with your GP.

If your results are borderline, or if you've been told to "keep an eye on it", this is an ideal opportunity to make positive dietary and lifestyle changes before medication becomes necessary.
