How to lower your cholesterol

Heart attack and stroke may cause 60% fewer deaths in the UK than they did a few decades ago, but they're still a major health hazard. Effective medicines to lower cholesterol and blood pressure have played a big part, but you can also stack the odds in your favour with lifestyle changes. Keeping your weight within the healthy range can significantly reduce levels of 'bad' LDL cholesterol and boost 'good' HDL cholesterol, which protects your heart.

Statins are extremely effective at lowering cholesterol and the health scares about them have been categorically debunked. It's hardly surprising that there has been a lot of media interest in statins - they're the second most commonly prescribed medicine in England and people are always interested in stories that relate to them personally.

However, many of the scare stories about side effects have largely been shown to be down to the 'nocebo effect'. This is the opposite of the placebo effect (where you're more likely to get better from a treatment if you believe you will, regardless of how effective it is). With the nocebo effect, you're more likely to get side effects if you're worried about them - and the more publicity there was about statins, the more people were worried.

In fact, a very well-designed study has proved that if people didn't know if they were taking a statin or a placebo (dummy) tablet, the two groups had equal numbers of side effects. Once these same patients knew if they were taking the 'real thing', the number of side effects in patients who were taking statins jumped.

While statins may be the best-known lipid-lowering medicines, they're not the only ones. If your cholesterol isn't adequately controlled with lifestyle and statin treatment - or you can't take statins - you may be prescribed a medicine called ezetimibe or a 'fibrate' medicine.

In the last couple of years, there have been several new medicines with powerful lipid-lowering properties developed. These target a protein called PCSK9, which is linked to high levels of 'bad' LDL cholesterol. Medicines in this group include Repatha (evolocumab), Praluent (alirocumab) and inclisiran (Leqvio), which has been found to reduce LDL cholesterol by about 50% with a single six-monthly injection. However, these medicines are usually only given to people at very high risk, and whose cholesterol isn't controlled with tablets.

Quitting smoking

Along with all the other benefits of stopping smoking, quitting can reduce furring up of your arteries and improve your cholesterol. Of course, quitting is easier said than done - nicotine is highly addictive and cigarettes are designed to deliver a rapid 'hit' of nicotine. But there's lots of free NHS support available to quit smoking and a wide range of tools that can help, ranging from nicotine replacement therapy (NRT) in patches, gum, inhalators, tablets, lozenges and sprays to vaping. Which alternative you use is up to you (ideally in discussion with your smoking cessation healthcare professional). But two things are clear - quitting is one of the best gifts you can give your body, and you're much more likely to quit successfully with expert support than by going 'cold turkey'.

Lifestyle changes and exercise

Exercise can help you lose weight, in combination with changes to your diet. As an added bonus, it can improve your cholesterol independent of weight loss as well. Regular exercise (ideally combining aerobic exercise - the kind that makes you mildly out of breath, with resistance exercises) can cut harmful LDL and raise HDL cholesterol.

The best form of exercise for you is the kind you enjoy - whether that's running, cycling, swimming, yoga, Pilates, spinning, HIIT (high-intensity interval training) or CrossFit. That's partly because you're more likely to stick with exercise if it isn't a chore. If you have a physical disability, you may need to adapt your routine, but there are still plenty of options. 30 minutes, five days a week is enough to improve your cholesterol, but any amount will help your heart if you can't manage that much.

Omega-3 fatty acids

Foods high in omega-3 fatty acids won't lower your LDL cholesterol but they have other heart-healthy benefits. Any oily fish, including sardines, mackerel, herring and salmon, are rich in omega 3s. But you can also find them in plant sources, including walnuts, soya or kidney beans and flax, chia or hemp seeds.

Introducing more fibre into your diet

When we think of fibre, we tend to focus on insoluble fibre - whole grain and wholemeal versions of refined foods like flour, bread and pasta, or beans and pulses. Insoluble fibre provides lots of benefits for your bowels, but soluble fibre has an additional superpower, reducing absorption of bad fats into your system. With a little imagination, you can up your intake of fibre through small tweaks to your diet.

Soluble fibre

Oats, barley, stone fruits (plums, nectarines, apricots), pears, apples, aubergines, avocadoes, carrots, broccoli, Brussels sprouts and sweet potatoes are good sources of soluble fibre. So are some beans, like black beans or kidney beans; nuts (walnuts, almonds, hazelnuts, peanuts); and seeds including sunflower seeds and flax seeds.


Try adding beans or pulses to stews - this can bulk them out, making them more economical, but they're also a delicious way to up your heart-healthy food intake. When summer comes, many fresh fruits become cheaper and more readily available. Eat it fresh or stew it (with as little sugar as possible!) for a tasty dessert. And hurrah! In addition to tasting delicious, strawberries are a great source of soluble fibre too. On the side, instead of cream, try a dollop of low-fat Greek-style yoghurt, which feels luxurious and is high in calcium and protein.

While you may think carrot, cucumber or celery sticks are dull, pairing them with home-made hummus can really perk them up. Just whiz up a drained tin of chick peas with a spoonful of tahini (sesame seed paste, available from most supermarkets), lemon juice, garlic and pepper. Equally easy but impressive as a party dip as well as for yourself is feta and beetroot hummus. Both are cheaper than the shop-bought alternatives and heart-healthy.

Seeds and nuts

Keep a pot of seeds and nuts in your handbag as a snack, to avoid being tempted by high-sugar alternatives. If you do want a sweet treat, home-made flapjack does at least have plenty of soluble fibre from the oats. Dried fruit, like figs and dates, shouldn't be eaten in unlimited quantities because they are high in sugar. But they feel indulgent and are a much better alternative than a chocolate bar.

Reducing your salt intake

On the whole, cooking from scratch is better for your heart health than ready-prepared foods. These are often high in hidden sugar and salt. While too much salt won't affect your cholesterol, it can raise your blood pressure - another major risk factor for heart disease as well as stroke.

It's the sodium in salt which affects blood pressure. A large new review of clinical studies shows that switching from 'standard' salt to salt substitutes, where some sodium is replaced by potassium, could cut early deaths and stroke/heart attack by 11%.

Rather than salt, use herbs, spices and lemon juice to season. Or if you do want to add salt, opt for a reduced sodium alternative, available in supermarkets.

Sterols and stanols

These are plant chemicals which are a similar size and shape to cholesterol. As they are absorbed from your gut, they block some cholesterol from being absorbed. It's hard to get enough even from a healthy diet, but fortified foods like Benecol and Flora ProActiv can help lower cholesterol. So too can soya-based foods, including soya milk or yoghurt, tofu and soya beans.
