High density lipoproteins (HDL) are biomolecules given the nickname "good cholesterol." HDL cholesterol is associated with improved heart health and better blood pressure. These molecules circulate the blood and remove plaque and harmful cholesterol from the blood and bring it back to the liver for recycling.
Significance
HDL cholesterol is shown to reduce the risk of plaque buildup in the arteries. Plaque buildup obstructs blood flow in the arteries and leads to heart attack and possible cardiac arrest.
Source
The liver manufactures most of the cholesterol needed by the body. Cholesterol obtained from the diet is usually LDL, which is considered the bad cholesterol.
Uses
Cholesterol is also used in other cellular functions. Cholesterol is also used in membrane structure of cells, and it is the precursor for steroids and hormones.
Considerations
Some drug therapies are under consideration to increase HDLs and lower LDLs. Niacin is a vitamin that has been shown to improve levels of HDLs.
Warning
Avoid foods high in fats to keep HDL levels at optimum levels. Meats, dairy and saturated fatty foods are associated with lower HDLs and an increase in LDLs, which is dangerous for heart health.
