Cholesterol measures

Total cholesterol means nothing in terms of health. Just as many people have fatal heart attacks with low total cholesterol as high, and there are additional health risks if it is too low. Flipping a coin gives you just as good data. I have seen people whose total cholesterol is high but who seem to have little risk. There may also be a genetic component to the baseline total cholesterol number that defies easy changes.


The main relevant and meaningful cholesterol number today is the ratio of total cholesterol to HDL cholesterol (over 5 is not good; lower means lower risk). This means that, if you have high total cholesterol but your ratio is good, your HDL number is high and that makes you better protected than someone whose HDL is low. Routine blood screenings now tend to include this important number. Homocysteine is another number that indicates your risk of inflammatory conditions affecting the brain and cardiovascular system.
