Blood cholesterol is a fatty substance produced naturally by your liver and found in your blood. Blood cholesterol is used for many different things in your body, but it can become a problem when there is too much of it in your blood.

Some foods contain cholesterol. This is called ‘dietary cholesterol’ and it is found only in animal products. For most people, eating foods high in dietary cholesterol actually only has a small influence on your blood cholesterol. High cholesterol levels in your blood are mainly caused by eating foods high in saturated fats and trans-fats.

Types of cholesterol


The two main types of blood cholesterol are:
  • low-density lipoprotein (LDL) – also known as ‘bad’ cholesterol because it can add to the build-up of plaque in your arteries and increase your risk of getting coronary heart disease
  • high-density lipoprotein (HDL) – also known as ‘good’ cholesterol because it can help to protect you against coronary heart disease.
In healthy people, it is normal to have more of the ‘bad’ LDL cholesterol when compared to ‘good’ HDL cholesterol, but you should aim to keep your LDL cholesterol down and HDL cholesterol up.

Measuring cholesterol


Most people with high cholesterol feel perfectly well and often have no symptoms. Therefore, the best way to find out if your cholesterol is high is to have a blood test. Ask your doctor for more information.

Causes of high cholesterol


Some causes of high blood cholesterol include:
  • Low intake of foods containing healthy, protective fats – including small amounts (about two teaspoons) of unsaturated spreads or oils or a small handful of nuts or seeds increases your intake of polyunsaturated and monounsaturated fats. These fats tend to increase the HDL cholesterol in your blood.
  • Saturated fats and trans-fats – high cholesterol is mainly caused by eating foods high in saturated fats and trans-fats. Foods high in saturated fat include fatty meats, full-fat dairy products, butter, coconut oil, palm oil and most deep-fried takeaway foods and commercially baked products, such as pies, biscuits, buns and pastries. Foods high in trans-fats include most deep-fried takeaway foods and commercially baked products.
  • Cholesterol in food (dietary cholesterol) – this has only a small effect on LDL cholesterol. Saturated fats and trans-fats in food cause a much greater increase in LDL cholesterol. You can include some cholesterol-rich foods, such as offal (liver, pâté and kidney) and prawns, as part of a healthy, balanced diet low in saturated fats and trans-fats. You can also eat up to six eggs a week as part of a healthy, balanced diet low in saturated and trans-fats, without increasing your risk of coronary heart disease.
  • Genetics – your family history may also affect your cholesterol level. Some people will have high cholesterol even if they follow a healthy, balanced diet low in saturated fats and trans-fats. These people may need to take cholesterol-lowering medicine as prescribed by their doctor.

Healthy eating tips and cholesterol


Changing some of the foods that you eat by following a healthy, balanced diet that is low in saturated fats and trans-fats can help to lower blood cholesterol.

It’s important to replace foods that contain unhealthy, saturated and trans-fats with foods that contain polyunsaturated and monounsaturated fats. Foods high in polyunsaturated fats include margarine spreads and oils such as sunflower, soybean and safflower; oily fish, and some nuts and seeds. Foods high in monounsaturated fats include margarine spreads and oils, such as olive, canola and peanut; avocados and some nuts.

The best starting point for a healthy diet is to eat a wide variety of foods from each of the five food groups, in the amounts recommended. This helps maintain a healthy and interesting diet, and provides a range of different nutrients to the body. Eating a variety of foods promotes good health and can help reduce the risk of disease.

The five food groups are:
  • fruit
  • vegetables and legumes/beans
  • lean meats and poultry, fish, eggs, tofu, nuts and seeds, legumes/beans
  • grain (cereal) foods, mostly wholegrain and high fibre varieties
  • milk, yoghurt, cheese and alternatives, mostly reduced fat.
Foods are grouped together because they provide similar amounts of key nutrients. For example, key nutrients of the milk, yoghurt, cheese and alternatives group include calcium and protein. These food groups make up the Australian Guide to Healthy Eating.

Additional tips to help you manage your cholesterol include:
  • Use spreads and margarines made from canola, sunflower or olive oil, and dairy blends that have earned the Heart Foundation tick, instead of butter.
  • Use a variety of oils for cooking – some good choices include canola, sunflower, soybean, olive, sesame and peanut oils.
  • Use salad dressings and mayonnaise made from oils such as canola, sunflower, soybean, olive, sesame and peanut oils.
  • Choose reduced-fat, low-fat or no-fat milk, yoghurt, custard and desserts, or calcium-added non-dairy food and drinks. Limit ice cream to no more than three times a week.
  • Have two to three portions (150 grams each) of oily fish every week. The fish may be fresh, frozen or canned.
  • Select lean meat (meat trimmed of fat, and poultry without skin).
  • Limit processed meats including sausages, and deli meats, such as salami.
  • Snack on plain, unsalted nuts and fresh fruit (eat two serves of fruit every day).
  • Incorporate peas (such as split peas), beans (such as haricot beans, kidney beans, baked beans, three-bean mix) or lentils into at least two meals a week.
  • Eat plenty of vegetables (aim for five ˝ cup serves of vegetables every day).
  • Choose wholegrain breads, cereal, pasta, rice and noodles.
  • Limit takeaway foods, such as pastries, pies, pizza, hot chips, fried fish, hamburgers and creamy pasta dishes, to once a week.
  • Limit salty, fatty and sugary snack foods, such as crisps, cakes, pastries, biscuits, lollies and chocolate, to once a week.
  • Limit foods such as liver, kidneys and pâté.
  • Include two or three serves of plant-sterol-enriched foods every day (for example, plant-sterol-enriched margarine, yoghurt, milk and bread).
  • Include up to six eggs every week.
If you are trying to lower your blood cholesterol, you should also aim to eat foods that are high in dietary fibre, particularly soluble fibre, because they can reduce the amount of LDL cholesterol in your blood. These foods include fruits, legumes (chickpeas, lentils, soybeans, four-bean mix and baked beans) and cereals (oats and barley).

Triglycerides in your blood


In addition to cholesterol, your blood also contains a type of fat called triglycerides, which are stored in your body’s fat deposits. Hormones release triglycerides to make energy between meals. When you eat, your body converts any calories it doesn’t need right away into triglycerides.

Like cholesterol, your body needs triglycerides to work properly. However, there is evidence to suggest that some people with high triglycerides are at increased risk of coronary heart disease. If you regularly eat more calories than you burn, you may have high triglycerides (hypertriglyceridaemia).

Treatment for high cholesterol


Making lifestyle changes, especially changing some of the foods you eat, is very important to help reduce high cholesterol or LDL cholesterol.

You may also need to take cholesterol-lowering medicines, such as statins, to help you to manage your cholesterol and reduce your risk of having a heart attack or stroke. Talk to your doctor about finding the most appropriate treatment for you.
