[QUOTE]Researchers on Thursday challenged a tenet of modern medicine that higher levels of "good" cholesterol automatically boost cardiovascular health.
In a study published in The Lancet, investigators said they found no evidence to back the belief that higher levels of high-density lipoprotein (HDL)
cholesterol routinely reduce the risk of a heart attack.
High concentrations of HDL are one of the big markers for blood tests.
They are monitored as much as low levels of "bad" cholesterol (low-density lipoprotein, or LDL) as a yardstick of dangerously clogged arteries.
The paper used a method called mendelian randomisation to compare heart-attack risk among people who inherited known genetic variants that gave
them higher HDL levels.
According to conventional wisdom, these individuals would have a lower risk of a coronary.
But the study, which looked at nearly 12,500 people with a history of a heart attack and over 41,000 otherwise healthy counterparts, found this was
not always the case.
The results are important because of the use of drugs, sometimes inflicting side effects, which are administered to boost HDL cholesterol levels.
"These results show that some ways of raising HDL cholesterol might not reduce risk of myocardial infarction [heart attack] in human beings," said
Sekar Kathiresan of Massachusetts General Hospital and Harvard Medical School.
"Therefore, if an intervention such as a drug raises HDL cholesterol, we cannot automatically assume that risk of myocardial infarction will be reduced."
In contrast, the study said "bad" cholesterol remained an accurate marker of cardiac risk.
[B]Separately, a study, also carried in Thursday's Lancet, confirmed the benefits of LDL-lowering statins for protecting people with no previous history of
cardiovascular disease.

propaganda has made cholesterol a devil.
there types of cholesterol...good and bad, and still people see it like a bad thing in general.
funny fact, when an ad of margarine says "0% cholesterol" you can loudly say "NO SHIT" because margarine is a green product and cholesterol is 100% animal.

You do realize that the article is talking about how HDL cholesterol (the good kind) might actually not be a major factor in the reduction of heart disease. It has nothing to do with anything in your post.
Don't both HDL and LDL have a function in the body, or am I remembering my health and nutrition class wrong?

They do, just too much LDL will clog up your arteries. It is a case of everything in moderation.

Cholesterol does not clog arteries by itself. First, you need inflammation in your arteries (caused by a large variety of things, most often high blood sugar and stress), second, the cholesterol has to go repair it, and third, the cholesterol MIGHT be oxidized. IF it is oxidized, you get plaque. If not, you're fine.
In other words "too much" cholesterol is false. It's too much inflammation.

Not exactly...

It's saying that artificially raising HDL may not increase heart health.

Yup, they are like caulk that is spread over damaged parts of your arteries. ECrown explained the rest pretty well.
dietary cholesterol is also the beginning of many of your important hormones, testosterone for example.
