The lower your blood cholesterol, the lower your risk of heart disease and stroke. The two main types of cholesterol in your body are referred to as HDLs and LDLs. Genetics and diet determine these levels. HDLs help prevent heart disease and help rid your body of cholesterol. LDLs leave fat on the inside of the blood vessels and increase your chance of heart disease.
Triglycerides are also important in managing total cholesterol.
If triglycerides are too high, your LDL cannot be determined. Total cholesterol should not be above 200. HDLs should be 45 or above. The HDL level can be slightly raised by moderate, regular exercise. LDLs should be 100 or below.
