"All this talk about cholesterol, lipids, and "good" and "bad" can be so confusing! Cholesterol and fat were things that we thought were always unhealthy, but research has shown that there are different types, some that increase the risk of heart disease and some that are actually protective! To check your risk of heart disease, your doctor may order a lipid profile test. This checks the levels of at least four lipid — fat — components in your blood:
Total cholesterol: This is the total amount of cholesterol floating in your bloodstream, some of which may offer protection against heart disease, and some of which may increase your risk. Your total cholesterol level should be less than 200 mg/dl (milligrams per deciliter).
LDL cholesterol: LDL, or low-density lipoprotein, cholesterol, usually labeled "bad," tends to adhere to the inside of blood vessel walls, building up blockages that can cause a heart attack. You want your LDL level to be low — ideally, less than 100 mg/dl, according to the American Heart Association. Between 100 and 129 is considered "near optimal," 130 to 159 is considered "borderline high," 160 to 189 is considered "high," and 190 and above is considered "very high." (at HealthQuest they teach us to remember L is for Lousy and it should Low)
HDL cholesterol: This type of cholesterol is the one many people think of as "good" cholesterol. Instead of sticking to the lining of blood vessels, HDL, or high-density lipoprotein, cholesterol (the so-called good cholesterol) is brought to the liver to be removed from the body — so it reduces your risk of heart disease. You want your HDL level to be high — at least 60 mg/dl or higher. A low HDL level (less than 40 mg/dl for men; less than 50 mg/dl for women) increases the risk of heart disease. (from HealthQuest H is for Healthy and it should be High)
Triglycerides: These fats are also included in a lipid profile. Although it's not clear whether high triglyceride levels are a risk factor for heart disease by themselves, they usually go hand in hand with other risk factors, such as high total cholesterol or low HDL. If you are obese, inactive, drink a lot of alcohol, or follow a diet very high in carbohydrates, you may have high triglycerides. Your triglyceride level should be less than 150 mg/dl. (for this, I got nothin')
This is a very important part of your overall health picture. If you haven't had your cholesterol tested lately, give it some thought. I was able to bring mine down last year - without any medication - through some simple changes. As a diabetic, I'm already at greater risk for heart disease so my numbers actually have to be better than those listed here. It doesn't take very long to have the test done and it could play a big part in how you focus your efforts to improve your health.
