Cholesterol 101: Ask the Expert
Think cholesterol is yesterday’s news? Think again! Recent research shows that cholesterol is something we all need to care about–regardless of age. What’s more, new studies show that there’s more than one type of diet that can help us maintain healthy blood cholesterol levels.
Dr. Kristina Petersen, Assistant Professor of Nutritional Sciences at Texas Tech and an American Heart Association (AHA) Nutrition Committee member, addresses some common questions about cholesterol and how we can best manage our cholesterol levels.
I feel great! Why check cholesterol?
High blood cholesterol doesn’t have symptoms. You might look fit and feel terrific, but still have high cholesterol which can lead to cardiovascular disease, the leading cause of death in the U.S. Knowing your cholesterol status can help you stay in control of your health.
Should I avoid food high in cholesterol?
Dietary cholesterol was once thought to be a primary driver of high blood cholesterol. However, more recent studies show that diets high in saturated fat are most related with high blood cholesterol. The AHA recommends limiting saturated fats, which makes it more likely you will lower your cholesterol to boot.
What else contributes?
In addition to your diet and genetics, lifestyle factors such as physical activity, smoking, and body weight can affect blood cholesterol. Aim to move more though both aerobic activity (walking, swimming, running) and strength training. If you smoke, speak with your healthcare provider to find ways to quit.
Note: Since everyone’s health history and nutritional needs are so different, please make sure that you talk with your doctor and a registered dietitian to get advice about the diet and exercise plan that‘s right for you.
