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
Troubleshooting & Solutions
Common Problems & Solutions
Why this happens
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.
How to fix it
- 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
Mistakes to avoid
- Replacing saturated fat with refined carbs instead of healthy fats
- Assuming 'low-fat' means 'heart-healthy'—many are loaded with sugar
When to seek help: See a doctor if levels stay above 160 mg/dL despite lifestyle changes; they may prescribe statins.
