Cholesterol: Get the Facts and Take Control

What is cholesterol and how does it impact my body? As a registered dietitian, those are two questions I’m commonly asked. Hopefully this post will help you better understand cholesterol and its effects.

Cholesterol is a type of fat found in your blood. Our bodies manufacture cholesterol. The waxy substance is also found naturally in animal foods, such as eggs, cheese and shellfish. We need it to help digest other foods and to make hormones and vitamin D, but too much of it can cause health concerns.

Approximately 17% of Americans have high cholesterol for a variety of reasons, most of which can be controlled. If you have too much cholesterol in your blood, it can harden and stick to your artery walls, causing them to narrow and result in a condition known as atherosclerosis. Clots can then form, further blocking the narrow arteries, and causing a heart attack. Eating a healthy diet, mostly plant foods, is one way to reduce the buildup of this fatty substance in your artery walls. High cholesterol levels – above 200 mg/dL or higher – can lead to heart disease.

To avoid having elevated cholesterol, make the following lifestyle adjustments.

  • Eat a diet that is low in saturated and trans fats.
  • Reduce your sodium intake.
  • Eat only enough calories each day to achieve or maintain a healthy weight.
  • Limit your carbohydrate intake. Complex carbohydrates are best: whole grains, fruits and vegetables.
  • Exercise daily. Just 20-30 minutes of aerobic exercise like biking, walking or swimming can help lower cholesterol.
  • If you smoke – QUIT!
  • Clean up your diet and prepare, cook and eat more of the foods that nature provides like fruits, veggies, nuts, seeds, whole grains, beans, peas and legumes. Eating a variety of these plant foods will ensure you receive plenty of nutrition, while still keeping your cholesterol intake to a minimum.

Take control and act now to lower your cholesterol and decrease your risk of heart disease!
