Quick Answer
Cholesterol is a waxy substance your body needs to build cells, but too much can increase heart disease risk. You can manage it by eating less saturated fat, exercising regularly, and getting tested annually after age 20.
Key Takeaways
- Check your cholesterol every 5 years starting at age 20—even if you feel fine
- Read nutrition labels: Look for 'trans fat = 0g' and low sodium
- Cook at home more—restaurant meals often hide hidden fats and sugars
- Helps diagnose risk for heart disease during routine blood work
- Guides treatment decisions for doctors prescribing medications
Plain English Explanation
Think of cholesterol like grease in pipes—too much builds up over time and can clog blood vessels, raising the risk of heart attack or stroke. Your liver makes most of your cholesterol, but your diet and lifestyle also play big roles. The goal isn’t to eliminate it completely (your body needs some), but to keep levels balanced for long-term health.

Common Problems & Solutions
LDL carries cholesterol to arteries where excess buildup forms plaques. Causes include diets high in red meat, fried foods, processed snacks, and lack of fiber.
- 1Limit saturated fats: Avoid fatty meats, full-fat dairy, and palm oil
- 2Eat more soluble fiber: Oats, beans, apples, and flaxseeds help absorb cholesterol
- 3Add plant sterols/stanols: Found in fortified margarines or orange juice
- Replacing saturated fat with refined carbs instead of healthy fats
- Assuming 'low-fat' means 'heart-healthy'—many are loaded with sugar
