Good cholesterol 'can turn nasty and clog arteries'

RATE THIS! +25
Posted in Science on 27th Jan, 2014 11:12 PM by AlexMuller

Good cholesterol also has a nasty side that can increase the risk of heart attacks, according to US doctors. "Good", or HDL, cholesterol normally helps to keep arteries clear and is good for heart health.

 
But the team at the Cleveland Clinic showed it can become abnormal and lead to blocked blood vessels.
 
 They say people should still eat healthily, but that the good cholesterol story is a more complex tale than previously thought.
 
Low-density lipoprotein (LDL) cholesterol is "bad" because it is deposited in the walls of arteries and causes hard plaques to build up that can cause blockages, resulting in heart attacks and stroke.
 
High-density lipoprotein (HDL) cholesterol is "good" because the cholesterol is instead shipped to the liver. The evidence shows that having a high ratio of good to bad cholesterol is good for health.
 
However, researchers at the Cleveland Clinic say trials aimed at boosting levels of HDL have "not been successful" and the role of good cholesterol is clearly more complicated.

They are providing very convincing new data-this interesting research. They describe the exact chemical change that causes the 'good' HDL cholesterol to become bad. Reply

Cholesterol is an important compound in our body. Recently, researchers found that cholesterol is broken down into 27HC, which can mimic oestrogen and produce the same effect as the hormone in some tissues. This links cholesterol with breast cancer Reply
