HDL is not so good for your health as you think

We always think a high level of "good" cholesterol in the blood as HDL, is better for health. However, new European research is suggesting that those with extremely high levels of good cholesterol have a higher mortality rate than people with normal levels 

The team also found excessive mortality for people with extremely low levels of HDL in the blood. Those with medium levels of HDL in the blood had the lowest mortality. For men, this level was 1.9 mmol/L. For women, it was 2.4 mmol/L.

Before that US studies have also shown similar correlations between levels of HDL cholesterol and excessive mortality but in specific population groups. This is the first time excessive mortality has been shown in a more general population
