You’ve probably heard about cholesterol in discussions about diet and heart health, but what exactly is cholesterol, and why is it significant?
Cholesterol is an essential component our bodies need, but when our cholesterol levels get too high, it can lead to significant health issues. Let’s explore what cholesterol is, the factors that influence it, and how you can maintain healthy levels to keep your heart in top shape.
Types of Cholesterol
Cholesterol is a waxy substance in your blood that’s needed for building cells, making hormones, and helping with digestion. However, not all cholesterol is created equal. The two main types of cholesterol are as follows:
Low-Density Lipoprotein (LDL)
Often termed “bad” cholesterol, LDL transports cholesterol to cells. Excessive LDL can accumulate in arterial walls, forming plaque and increasing the risk of atherosclerosis, heart disease, and stroke.
High-Density Lipoprotein (HDL)
Known as “good” cholesterol, HDL assists in removing excess cholesterol from the bloodstream, returning it to the liver for elimination. Higher HDL levels are usually beneficial, reducing the risk of heart disease.
Triglycerides
Triglycerides store unused calories and provide energy to the body. Elevated triglycerides, especially when coupled with high LDL or low HDL, can substantially heighten your risk of cardiovascular disease.
Factors Affecting Cholesterol Levels
Several factors influence your cholesterol levels. Some are within your control, while others are not:
Diet
Eating foods high in saturated fats, trans fats, and cholesterol (like red meat and full-fat dairy) can increase your “bad” cholesterol. Eating healthier fats, like those found in olive oil, nuts, and fish, can help improve your cholesterol levels.
Physical Activity
Regular physical activity can increase your “good” cholesterol and lower the “bad” cholesterol and triglycerides. Staying active also helps you maintain a healthy weight, which is crucial for keeping cholesterol levels in check.
Weight
Being overweight or obese can negatively impact your cholesterol levels. Excess weight can increase LDL cholesterol and triglycerides while also lowering HDL cholesterol. Losing even a small amount of weight can significantly improve your cholesterol profile.
Smoking
Smoking has a detrimental effect on your cholesterol levels. It makes your LDL cholesterol ‘stickier,’ which means it’s more likely to cling to artery walls and form blockages. Smoking also lowers the level of HDL cholesterol in your body.
Genetics
Your genetics play a significant role in your cholesterol levels. Some people inherit genes that cause high cholesterol, a condition known as familial hypercholesterolemia. If high cholesterol runs in your family, you may need to take extra steps to manage your levels.
Age and Gender
Cholesterol levels tend to increase as you age. Before menopause, women usually have lower LDL levels than men because of higher oestrogen levels, which helps maintain higher HDL levels. After menopause, women’s LDL levels often rise. Men generally have higher LDL levels throughout their lives compared to women.
Medical Conditions
Certain medical conditions can affect your cholesterol levels. Diabetes, hypothyroidism, and liver or kidney diseases can all lead to higher cholesterol levels. Managing these conditions with the help of your healthcare provider can help keep your cholesterol in check.
Medications
Some medications, including those for high blood pressure, HIV, and acne, can affect your cholesterol levels. If you are concerned about the impact of your medications, talk to your doctor about potential alternatives or solutions.
How To Maintain Healthy Cholesterol Levels
Maintaining healthy cholesterol levels is vital to reducing the risk of heart disease and ensuring a healthier you. Here are some practical tips to help you keep your cholesterol in check:
Eat a Heart-Healthy Diet
Focus on a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Foods high in soluble fibre, such as oats, beans, lentils, and certain fruits, can help reduce LDL cholesterol. Include fatty fish like salmon and mackerel in your diet, as they are rich in omega-3 fatty acids, which can help lower triglycerides.
Exercise Regularly
Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise each week. Activities such as brisk walking, jogging, swimming, or cycling can help improve your cholesterol levels. Strength training exercises at least twice a week can also be beneficial.
Maintain a Healthy Weight
Losing excess weight can significantly improve your cholesterol levels. Even a modest weight loss of 5-10% of your body weight can make a difference. Focus on combining a healthy diet with regular physical activity to achieve and maintain a healthy weight.
Avoid Smoking and Limit Alcohol Intake
Quitting smoking is one of the best things you can do for your heart health. Additionally, limiting alcohol intake is crucial, as excessive alcohol consumption can increase triglyceride levels and the risk of heart disease.
Stress Management
Chronic stress can negatively impact your cholesterol levels and overall heart health. Engage in stress-reducing activities like yoga, meditation, deep breathing exercises, or hobbies you enjoy. Getting adequate sleep is also essential for managing stress and maintaining heart health.
Regular Check-Ups
Keep track of your cholesterol levels with regular blood tests. Your doctor can help determine how often you need these tests based on your risk factors and overall health. If your cholesterol is high, your doctor may suggest lifestyle changes or medications to help manage it.
