Understanding what LDL is, what it does and why it is so important can be confusing at times. When your doctor tells you your LDL --- low-density lipoprotein --- level is too high and that you need to eat this or take that, you might do it just because he says to. It is in your best interest, however, to understand what an average LDL level is and the effects on your health when yours goes beyond that.
Purpose
LDL is a special protein carrier that the cholesterol in your body relies on to reach your cells, enabling it to build cell membranes. The LDL combines with the cholesterol and circulates through your blood. Average --- or healthy --- levels result when no excess LDL remains in your blood.
Significance
Low-density lipoprotein is the major carrier of cholesterol in your blood, according to the American Heart Association. Excess amounts of LDL build up in the walls of the arteries leading to your heart and brain, resulting in narrow passageways for your blood. This can cause blood clots to form, and you can experience a heart attack or stroke depending on the artery the clot is in. Maintaining average LDL levels reduces the risk of these medical complications.
Risk Factors
Although your goal is to have and maintain a healthy LDL cholesterol level, certain risk factors can increase your chances of developing a high LDL level. These include obesity, lack of exercise, a diet high in fat and cholesterol, a family history of heart disease and medical conditions, such as diabetes.
Identification
A lipid profile is the only way to detect and determine what your LDL level is. When your doctor orders this blood test, he hopes to see a reading of 100 mg/dL or less --- this is optimal. If your test returns with a reading of 100 to 129 mg/dL, you are still within a healthy, average range, as the American Heart Association points out.
Prevention/Solution
You can reach or maintain an average LDL cholesterol level by making a few dietary and lifestyle changes. Eat less fat; saturated fats, such as red meat and whole-fat dairy products, should only comprise seven percent of your total daily calories. Replace snack foods and baked goods with fruits and vegetables when you feel the urge to munch. Walk for 30 minutes each day, even if it's in three 10-minute intervals. Step on the scale; if you need to drop a few pounds, do so. A weight loss of even five or 10 lbs. helps. Increase your fiber intake; soluble fiber absorbs cholesterol in the blood before it reaches your artery walls.
Considerations
If you haven't been to your doctor recently, make an appointment and ask for a lipid blood test. Knowing what your LDL levels are can protect your heart and overall health. This is especially important if you have any risk factors for high cholesterol.
