HDL cholesterol

 (āch′dē′ĕl′)
n.
A lipoprotein with a relatively high concentration of protein and low concentration of lipids that incorporates cholesterol and transports it to the liver. High levels are associated with a decreased risk of atherosclerosis and coronary artery disease. Also called high-density lipoprotein.

Summary: Most of us should aim for moderation regarding serum levels of HDL cholesterol
Conversely, they tend to say that HDL cholesterol is "good" because it helps remove LDL cholesterol from the body.
Now research is showing that you can have too much HDL cholesterol.
People with HDL cholesterol levels greater than 60 mg/dl had a nearly 50 per cent increased risk of dying from a cardiovascular cause or having a heart attack compared to those with HDL cholesterol levels 41-60 mg/dl.
HDL cholesterol has been considered 'good' because the HDL molecule is involved in the transport of cholesterol from the blood and blood vessel walls to the liver and ultimately out of the body, thereby reducing the risk of clogged arteries and atherosclerosis, the researchers explained.
However, the risk increased in people with low levels (less than 41 mg/dl) as well as very high levels (greater than 60 mg/dl) of HDL cholesterol. People with HDL cholesterol levels greater than 60 mg/dl had a nearly 50 per cent increased risk of dying from a cardiovascular cause or having a heart attack compared to those with HDL cholesterol levels 41-60 mg/dl.
The researchers found that serum 25(OH)D was negatively associated with total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides after adjustment for age and sex.
More specifically, above-average visit-to-visit variability in fasting triglycerides, LDL cholesterol, or HDL cholesterol in atorvastatin-treated patients with known coronary artery disease proved to be a strong and independent predictor of coronary and cardiovascular events in a post hoc analysis of the landmark Treating to New Targets (TNT) trial (N Engl J Med 2005;352: 1425-35).

While there is an overwhelming amount of evidence relating high levels of total LDL cholesterol and low level of HDL cholesterol with coronary atherosclerosis, the relation between blood lipids and lipoproteins and cerebrovascular atherosclerosis is less clear.
Eating almonds on a regular basis may help boost levels of HDL cholesterol while simultaneously improving the way it removes cholesterol from the body, according to researchers.
