What Are LDLs?
How long should you walk or ride a bike every day to help get your HDL levels where they need to be?
Hi, I’m Laureen Wallravin, Certified Nutritional Therapist and founder of RelishedFood.com. I'm here today for about.com to answer the question: What is LDL cholesterol?Low-density lipoprotein, or LDL cholesterol, often referred to as “bad” cholesterol, plays a key role in heart health. LDL cholesterol has a tendency to get stuck on the walls of arteries, causing a build-up of plaque. This can ultimately lead to the narrowing of arteries or even blockage.While cholesterol is produced in the liver, the foods we eat and our level of activity plays a direct role in the amount of LDL cholesterol in our blood stream. Living a sedentary lifestyle and eating foods that feature high levels of low-quality saturated fats, such as sausage, liver, and fatty cuts of beef, can work to elevate your LDL levels. Smoking can also lead to elevated levels of LDL cholesterol.The general consensus within the medical community is that maintaining LDL levels of less than 100 milligrams per deciliter is best. Levels approaching or exceeding 160 milligrams per deciliter are considered high.While exercise and a balanced diet can certainly improve cardiovascular health, they may not be enough on their own. Depending on your individual health history and a wide array of other factors, you may need additional help in lowering your LDL levels. Following your physician's advice is the best plan of attack, and in some instances this may include drug therapy. Heart health is the key to longevity, so keeping your LDL cholesterol in check is a good idea.Thanks for watching. To learn more, visit us on the web at About.com.
