Some people with high levels of supposedly “good” cholesterol are at much greater risk of heart disease, a study suggests.
A bloodstream tussle takes place between “bad” cholesterol dumping fatty material in the arteries and good cholesterol taking it away.
But a Cambridge University study in the journal Science showed more good cholesterol was not always better.
It is thought the findings may help find new ways to protect the heart.
Eating olive oil, fish and nuts raises levels of high-density lipoprotein (HDL) – which is more commonly known as good cholesterol.
It is one of the things doctors test for when predicting your risk of a heart attack.
However, repeated trials that raise HDL with drugs have flopped, leading doctors to think something else is going on.
