Advanced lipid testing and other markers can reveal key aspects of metabolic health, according to the experts.
Imagine a room full of your closest friends and family. The odds are that heart disease will affect at least one of them. Heart disease is the leading cause of death for both men and women in the United States, claiming a life every 33 seconds. For decades, we have been told that lowering low-density liproprotein (LDL) cholesterol—so-called bad cholesterol—is the key to heart health. But with odds like that, something isn’t adding up.
“I think the current model is oversimplified and rather myopic,” Nick Norwitz, a Harvard medical student who holds a doctorate in physiology from Oxford, told The Epoch Times. “LDL is the most common biomarker now. There are better markers.”
Beyond LDL
You might have had your cholesterol checked and been told that everything looks normal. But those standard tests may only be telling part of the story. Traditional cholesterol tests, while still valuable, measure cholesterol amounts.
They miss important details about the quality and behavior of cholesterol particles and other key metabolic factors. This is why a “normal” cholesterol level isn’t always a guarantee of low risk. To understand your risk, you may need to dig deeper with advanced lipid testing.
Emerging research is painting a new picture: Focusing solely on “bad” cholesterol misses pivotal pieces of the puzzle. Factors such as the size and composition of particles of high-density lipoprotein (HDL) cholesterol—the so-called good cholesterol—along with triglyceride levels and overall metabolic health, are equally, if not more, important in preventing heart disease. This new understanding is reshaping how we assess heart health, shifting the lens to a more comprehensive, preventive, and personalized approach that prioritizes lifestyle changes such as diet and exercise, according to Norwitz.
Metabolic Health and Heart Disease
Think of your body’s metabolic health as the engine of a car. When it’s running smoothly, you feel energetic and well.
But imagine feeling constantly tired, noticing your clothes are tighter around the middle, and struggling to keep your blood sugar in check. Now the engine isn’t running as well. These symptoms could be signs of metabolic syndrome—a cluster of health issues that increase your risk of heart disease. Metabolic syndrome is like having several warning lights flashing on your dashboard: belly fat, high triglycerides, low HDL cholesterol, high blood pressure, and high blood sugar.
