Here is a brief report of how it works in general. Cholesterol is a healing substance in the body (and many other important functions), and response to arterial inflammation, which will be performed in combination with other substances to form "plaque" as a healing agent in the lining of arteries.
Levels of inflammation in your body can be measured by what we have tests CRP (C-reactive protein). The accuracy of this test is still room for improvement, because it can change depending on time and other factors, but it is a better indicator of heart disease risk than cholesterol tests (which is almost useless for determining the risk of heart disease).
Another test is more important, than the level of cholesterol for heart disease is a test for serum homocysteine levels. The next time your doctor that your blood cholesterol testing to get the press to CRP and homocysteine tests instead. He should be fully aware of the accuracy test them until recently.
Especially if you have significant internal inflammation, this memorial plaque is stored as a healing agent, whether you have high cholesterol or low. On the other hand, if you do not have inflammation, high cholesterol levels not only circulated to the arterial lining. And more important is to bridle inflammation than cholesterol reduction.
Lower your cholesterol asasault not the root problem (which is the real reason for the inflammation in you). Lower your cholesterol doing anything, but pharmaceutical companies make money, and may leave you with a whole range of possible side negative effects.
