  • Good & Bad Cholesterol…
    Cholesterol is a small, soft, waxy molecule produced mainly by the liver and circulated throughout the bloodstream. Cells need cholesterol to form their outer cell membranes. Sounds like cholesterol is pretty important so far, right? Yes, it is. The problem isn’t a lack of cholesterol. The problem is that many people have a cholesterol level that’s too high. Like everything else with the body there is a healthy balance! Obtaining that balance can be tricky especially if your family genetics cause a large production of cholesterol. This is why it’s important to know if high cholesterol is one of your risk factors and address it as soon as possible.

    You’ve probably heard that there is good cholesterol and there is bad cholesterol. The good cholesterol is called HDL (High-Density Lipoprotein). HDL is good because it carries the bad cholesterol back to the liver to be disposed of. The bad cholesterol is called LDL (Low-Density Lipoprotein). Excess amounts of this cholesterol will build up in the walls of arteries. This is known as plaque build-up or atherosclerosis. Plaque build-up in Coronary Arteries is called Coronary Artery Disease. This is the major source of all Heart Attacks!

    A Lipid Panel is a simple blood test that measures the amount of fats in your blood stream. In addition to cholesterol, a lipid panel also measures Triglycerides. Triglycerides play an important role in metabolism as an energy source and transporter of dietary fat. Triglycerides also contain more than twice as much energy as carbohydrates and proteins. However, high levels of triglycerides in the blood stream increase your risk for blocked arteries and heart disease.

    All of this information has pertained to a standard lipid panel, however, there is much more to cholesterol than just this. In reality, there are subcategories of HDL and LDL. And to make matters more confusing, it turns out that some HDL molecules are more protective than others. And some LDL molecules are worse than others.

    There are 2 types of HDL molecules: large, buoyant HDL molecules that are the most protective, & small, dense HDL molecules that are the least protective. Likewise, there are 2 types of LDL molecules. Large, buoyant LDL molecules that are the least harmful. And, small, dense LDL molecules that are the most harmful. Understanding these subcategories of cholesterol is the most accurate way to assess your true risk factor.

    A standard lipid profile will not break down the sub-categories of cholesterol. Currently, the most accurate cholesterol test available is called the VAP test (Vertical Auto Profile).

    The VAP test (Vertical Auto Profile) test is still fairly new and many practitioners are not using it yet. Ask your Doctor if they’re familiar with this test. If not, you can download a brief letter describing the test at http://www.atherotech.com/consumers/letter_to_doctor.asp Give it to your Doctor and ask them to order this test for you.

    Hope this was helpful…
    Good luck…

  • High-density lipoproteins (HDL) are composed mainly of proteins, with only small amounts of cholesterol. HDLs are often referred to as "good cholesterol" because they help remove cholesterol from artery walls and transport it to the liver for elimination from the body. Higher HDL levels actually protect against coronary heart disease.

    Low-density lipoproteins (LDL) are composed mainly of cholesterol and have very little protein. They are often referred to as "bad cholesterol" because they are primarily responsible for depositing cholesterol within arteries. High levels of LDLs are associated with an increased risk for coronary heart disease

    Cholesterol is a waxy, fat-like substance that is made in the body by the liver. Cholesterol forms part of every cell in the body and serves many vital functions

    You want a low cholesterol

  • HDL = High Density Lipoprotein = "Good Cholesterol"
    LDL = Low Density Lipoportein = "Bad Cholesterol"

    The measurements I’m familiar with in the US are: mg/dl.
    Total of HDL + LDL should be less than or = 200.
    Ideally, HDL should be around 35 to 45 mg/dl and LDL should be around 130 mg/dl or less.

    From: http://www.scotpho.org.uk/web/site/home/Clinicalriskfactors/HighCholesterol/highcholesterol_intro.asp

    "Cholesterol is a fat-like substance present normally in the blood, and in every cell of the body. The level at which it is present in the blood varies, and the higher the cholesterol level in an individual, the greater the risk of coronary heart disease (CHD) and stroke. A raised cholesterol level is therefore a risk factor for these diseases, and is especially important when other risk factors are also present.

    There is some evidence that there is virtually no lower limit at which further lowering of cholesterol does not decrease risk. However, in the UK the consensus is that 6.5 mmol/l is the point at which the total cholesterol level becomes ‘raised’. A report from the World Health Organization has defined an ‘optimal’ cholesterol level as 3.8 mmol/l.

    High cholesterol in the blood is related to the intake of saturated fat in the diet, rather than to cholesterol intake."

  • There is absolutely NO such thing as good and bad cholesterol.

    Cholesterol is ONE SUBSTANCE.

    Lipoproteins are NOT cholesterol at all.

    Cholesterol is a pearly waxy solid alcohol.
