Triglycerides

What is lipid metabolism?

Lipid metabolism is the process by which your body absorbs, uses and breaks down fats (lipids). This mainly takes place in the liver and intestines. Fats from your diet are first broken down into smaller components, including triglycerides and cholesterol. They are then transported through the blood to different parts of the body, where they are used as an energy source or stored for later use.

What role do fats and cholesterol play in the body?

Fats and cholesterol are important for your body. Fats provide energy and help your body absorb certain vitamins, such as vitamins A, D, E and K. Cholesterol is needed to produce hormones and bile, which supports digestion, and is an important component of cell membranes. Fats and cholesterol are therefore essential, but excessive amounts can be harmful.

What is the difference between good and bad cholesterol?

Cholesterol is transported through the blood by particles called LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL is often referred to as ‘bad cholesterol’ because excessive amounts can contribute to the build-up of cholesterol in the artery walls. This can increase the risk of cardiovascular disease. HDL is often called ‘good cholesterol’ because it helps transport excess cholesterol away from the blood and back to the liver, where it is processed.

Which factors affect cholesterol levels?

Various factors can affect your cholesterol levels. Diet plays an important role, but genetics, age, sex, body weight and physical activity are also relevant. Certain conditions, such as diabetes and thyroid disorders, can affect cholesterol levels as well. Some medications can also increase or decrease cholesterol levels.

Can diet affect cholesterol levels?

Yes, diet can have a significant effect on cholesterol levels. Saturated fats, such as those found in fatty meats, full-fat dairy products and biscuits, can increase LDL cholesterol. Trans fats, found in some margarines and snacks, can also have an adverse effect. Unsaturated fats, such as those found in nuts, fish and olive oil, as well as fibre-rich foods such as vegetables, fruit and wholegrain products, can help maintain healthy cholesterol levels.

Are high cholesterol levels common?

High cholesterol levels are common, particularly among adults. You often do not notice anything yourself because high cholesterol usually does not cause symptoms. Cholesterol levels may therefore be checked as part of a health check or if you have an increased risk of cardiovascular disease.

Can cholesterol levels change later in life?

Yes, cholesterol levels can change as you get older. In many people, cholesterol levels increase with age, particularly in women after menopause. Changes in lifestyle, body weight or overall health can also affect cholesterol levels.

How can you support healthy cholesterol levels?

You can support healthy cholesterol levels by eating a balanced diet, exercising regularly, maintaining a healthy weight and not smoking. Eat plenty of vegetables, fruit, wholegrain products, nuts and fish, and limit saturated and trans fats. Regular physical activity, such as walking or cycling, can also help. Medication may sometimes be necessary, depending on your individual risk. Discuss with your doctor what is most appropriate for your situation.
