Sterols are fat compounds in food, but only animal foods contain cholesterol (meats, eggs, fish, poultry, and dairy products).
LDL's are Bad...
High levels of low-density lipoproteins (LDL) have been linked to heart disease.
HDL's are Good...
Elevated levels of high-density lipoproteins (HDL) represent cholesterol that is being returned to the liver for absorption and excretion. It appears that high levels of HDL's provide a protective effect from heart attacks. Marine foods are generally rich with omega-3 fatty acids and this can lower blood pressure, especially for those with hypertension.
