The Ultimate List of Foods That Reduce Cholesterol Levels

Understanding Cholesterol Levels

Cholesterol is a waxy, fat-like substance that is essential for human life. It is involved in the formation of cell membranes, certain hormones, and Vitamin D. However, elevated levels of cholesterol can lead to cardiovascular diseases.

Types of Cholesterol

  1. Low-Density Lipoprotein (LDL)
    • Often termed as “bad” cholesterol.
    • Transports cholesterol from the liver to the body’s cells.
    • High levels can result in cholesterol buildup in arteries, raising heart disease risk.
  2. High-Density Lipoprotein (HDL)
    • Known as “good” cholesterol.
    • Carries cholesterol away from the arteries and back to the liver.
    • Higher levels are typically associated with a lower risk of heart disease.
  3. Triglycerides
    • Different type of fat found in the blood.
    • High levels can also increase heart disease risk, especially when combined with high LDL or low HDL.

Cholesterol Measurements

Cholesterol levels are measured in milligrams per decilitre (mg/dL) in the blood. A lipid profile will typically include:

  • Total Cholesterol
    • Indicates the overall cholesterol concentration. Ideal levels are less than 200 mg/dL.
  • LDL Cholesterol
    • Optimal levels are lower than 100 mg/dL.
    • Near optimal/above optimal: 100-129 mg/dL.
    • Borderline high: 130-159 mg/dL.
    • High: 160-189 mg/dL.
    • Very high: 190 mg/dL and above.
  • HDL Cholesterol
    • Higher levels are better.
    • Low: less than 40 mg/dL in men, less than 50 mg/dL in women.
    • Desirable: 60 mg/dL and above.
  • Triglycerides
    • Normal: less than 150 mg/dL.
    • Borderline high: 150-199 mg/dL.
    • High: 200-499 mg/dL.
    • Very high: 500 mg/dL and above.

Importance of Cholesterol Control

High cholesterol typically doesn’t cause symptoms. Regular screening is vital as elevated cholesterol is a significant risk factor for:

  • Atherosclerosis:
    • Plaque buildup in arteries.
