But many people—including 94 million American adults, according to the Centers for Disease Control and Prevention (CDC)—have high cholesterol levels, which puts them at an increased risk of heart disease and stroke.
Romit Bhattacharya, MD, a Mass General Brigham cardiologist, explains what it really means to have unhealthy cholesterol levels. Dr. Bhattacharya is the associate director of the Cardiac Lifestyle Program at Massachusetts General Hospital. He shares tips about the worst and best foods to eat when you have high cholesterol.
What is cholesterol?
Many people are familiar with the term “cholesterol,” and have heard that high cholesterol is dangerous. But to truly grasp the value of healthy cholesterol levels, it’s important to understand what the word means.
“Cholesterol is a particle in the blood that all humans and animals need to live,” says Dr. Bhattacharya. “But in today’s day and age, we end up with too much of it. Its primary role is to create a membrane—like a bubble—around molecules in the body and help them travel from place to place.”
