Cholesterol: Causes, Risks, and How to Lower It

Clogged arteries with cholesterol

Cholesterol is a fatty substance found in your blood, essential for building cells and producing hormones. However, high levels of cholesterol can be harmful to your health, increasing the risk of heart disease and other conditions.

What Causes Cholesterol to Increase? 

Several factors can lead to elevated cholesterol levels, including:

  • Unhealthy diet: High intake of saturated fats (found in red meat, dairy, and processed foods) and trans fats (often in fried and packaged foods).
  • Lack of physical activity: Sedentary lifestyles can raise levels of "bad" LDL cholesterol and lower "good" HDL cholesterol.
  • Smoking: Cigarette smoke damages blood vessels and lowers HDL levels.
  • Excessive alcohol consumption: Regular heavy drinking can increase overall levels.
  • Genetics: Family history can make some people more prone to high cholesterol.

What Are the Effects of High Cholesterol on Health? 

High cholesterol can lead to the build-up of plaque in the arteries (atherosclerosis), which narrows them and restricts blood flow. This can cause:

  • Heart attacks: If blood flow to the heart is blocked.
  • Strokes: If blood flow to the brain is interrupted.
  • Peripheral artery disease: Reduced circulation in the limbs.

How Can Cholesterol Levels Be Lowered?

Lowering levels involves lifestyle changes and, in some cases, medication. Here are some effective strategies:

  1. Eat a balanced diet: Focus on fruits, vegetables, whole grains, and lean proteins. Reduce the intake of saturated and trans fats.
  2. Exercise regularly: Aim for at least 30 minutes of moderate exercise most days of the week. Activities like brisk walking, cycling, or swimming can improve your levels.
  3. Quit smoking: Giving up smoking improves your HDL levels and overall cardiovascular health.
  4. Limit alcohol intake: Drink in moderation; ideally, no more than one drink per day for women and two for men.

The Role of Omega-3 Supplements 

Omega-3 fatty acids, commonly found in fish oil, can help reduce levels by lowering triglyceride levels (another type of fat in the blood) and supporting heart health. Incorporating omega-3-rich foods like salmon, mackerel, and walnuts, or taking omega-3 supplements can be a beneficial addition to your diet.
