The high cholesterol is definitely a problem for our health, especially that of our heart and our blood vessels. Keep tabs on the levels of these fats in the blood is one of the first things we know we should do, through a healthy balanced diet and a lifestyle that is as dynamic as possible and free from harmful vices such as cigarettes or too alcohol. As our doctor he prescribes blood tests, that an adult in good health should still be performed once a year, between the values ​​to be measured there is always the total cholesterol. For a more accurate picture, however, it is important to specify what we are talking about cholesterol, “good” and “bad” are the two basic definitions which we denote respectively cholesterol LDL and the HDL . What is the difference?


Cholesterol “good” or “bad”?

To date we have always heard that having a high level of HDL cholesterol in the blood would be able to balance an equally high level of LDL . In practice, while the “bad” clogs the arteries , thus exposing us to the risk of heart damage, including heart attack and stroke , the “good” acts as a sweeper and clear the blood vessels. So, all right?
In reality, things are not exactly as it seems. The people who are genetically predisposed to produce cholesterol and have the heart at risk, in fact, are not protected by high levels of HDL. The latest studies tell us that the probability of suffering a myocardial infarction is lower in those who have the “good” cholesterol high. In essence, high cholesterol, which is LDL or HDL, it also incurs the risk of heart attacks in those who already prepared. For this you should consider the total cholesterol , and try not to exceed the threshold-limit.

“Good” cholesterol HDL, the collapse of a myth

The study has overturned a rooted scientific belief, one on ‘ protective effect of cholesterol HDL , was conducted by researchers at Massachusetts General Hospital in Boston in collaboration with the foundation Hospital of Milan, the company University Hospital of Parma and l ‘ University of Milan and published in the journal Lancet . The research was based on analysis of samples of DNA from 120 thousand people, in which he sought the so-called variant of the gene EOG , associated with the production of HDL cholesterol. In a subgroup of 53 thousand people have always valued other genetic variants associated with increased production of “good” cholesterol. Analyzing all the data at the end of the response was disappointing: “Certain genetic mechanisms that increase the levels of HDL cholesterol in the blood do not appear to lower the risk of myocardial infarction “, according to the experts.

A result so clear that one of the authors of the study Italian, “Perhaps, then, it is not worth to develop drugs to try to increase it. The research data will test a dogma and that is that high levels of good cholesterol HDL protect against risks stroke. This finding also confirms what we have seen with other studies, where they were experimenting with drugs that increase the levels of HDL cholesterol, but not at all diminished the risk of heart attacks. ” Resign ourselves, if our total cholesterol exceeds dangerous levels, you need to run for cover.
