Most of us know that too much cholesterol promotes heart disease. And many know that cholesterol comes in good and bad forms. “Bad” (low-density lipoprotein, or LDL) cholesterol clogs the arteries that pump blood to the heart and feed the brain, raising the risk of heart attack and stroke. “Good” (high-density lipoprotein, or HDL) cholesterol removes excess cholesterol and fat from the bloodstream, keeping arteries healthy.
But a little knowledge can be a dangerous thing: this good versus bad scenario offers a simplistic view of cholesterol’s role in heart disease.
