What is lipid metabolism in relation to cholesterol?
Lipid metabolism refers to how your body processes, uses and stores fats. Cholesterol is one of these fats. Your body obtains fats and cholesterol from food, but also produces them itself, mainly in the liver. Lipid metabolism ensures that these substances reach the right places in the body and are used for energy or as building materials.
What role do fats and cholesterol play in the body?
Fats and cholesterol are important for your health. They provide energy, help produce cells and hormones, and protect your organs. Cholesterol is also needed to produce bile, which helps digest fats. Your body therefore needs fats and cholesterol, but too much can be harmful.
What is the difference between good and bad cholesterol?
There are two main types of cholesterol in your blood: HDL (‘good’ cholesterol) and LDL (‘bad’ cholesterol). HDL helps transport excess cholesterol away from your blood vessels to the liver, where it is processed. LDL can accumulate in the blood vessels, which can contribute to narrowing of the arteries and increase the risk of cardiovascular disease.
Which factors affect cholesterol levels?
Various factors can affect your cholesterol levels. These include your diet, body weight, age, genetics, physical activity and certain medical conditions or medications. Smoking and stress can also play a role. Sometimes cholesterol levels are elevated without an obvious cause.
Can diet affect cholesterol levels?
Yes, diet can have a significant effect on your cholesterol levels. Saturated fats, such as those found in fatty meats, full-fat dairy products and snacks, can increase LDL cholesterol. Trans fats, found in some biscuits and baked goods, can also have an adverse effect. Unsaturated fats, such as those found in nuts, fish and plant-based oils, can help maintain healthy cholesterol levels. Fibre-rich foods, such as vegetables, fruit and wholegrain products, are also beneficial.
Are high cholesterol levels common?
Yes, elevated cholesterol levels are common, particularly among adults. You often do not notice anything because high cholesterol usually does not cause symptoms. This is why regular testing can be useful, especially as you get older or if you have other risk factors.
Can cholesterol levels change later in life?
Yes, your cholesterol levels can change as you get older. Cholesterol often increases with age, particularly in women after menopause. Changes in lifestyle, body weight or overall health can also affect your cholesterol levels.
How can you support healthy cholesterol levels?
You can do several things to support healthy cholesterol levels. Eat a healthy, varied diet with limited saturated fat and plenty of fibre. Exercise regularly, stop smoking and try to maintain a healthy weight. Medication may sometimes be necessary, but lifestyle changes can also have a significant effect. If you have questions or concerns about your cholesterol, discuss them with your doctor.
