Many people don't know what cholesterol is let alone know what their cholesterol levels may be. One thing that is known is: having high cholesterol can contribute to heart disease.
When fatty deposits filled with bad cholesterol build up on your arteries, it can cause a lack of blood flow and oxygen to your heart. This can result in heart disease.
A person's total cholesterol level should be lower than 200 mg/dl. Your LDL (this is the bad cholesterol in your blood) should be less than 70 mg/dl if you have an existing heart disease.
Your LDL level should be less than 100 mg/dl if you are at risk for heart disease and it should be no higher than 130 mg/dl if you have no risk factors.
It is important to raise your good cholesterol (HDL) and lower your bad (LDL). A goal for good cholesterol (HDL) is 40 mg/dl, and anything higher is wonderful.
People at risk for heart disease, and even those not at risk, should have their cholesterol levels checked regularly. By simply changing your diet and exercising, you can lower your cholesterol.
