When you and your doctor discuss your cholesterol level, do you understand what it means? Cholesterol is a fatty substance that is present in the blood. Not all cholesterol is considered to be bad for you. LDL cholesterol levels are the type that doctors monitor and is considered to be “bad cholesterol.” This is the type that can build up and actually block your arteries, leading to heart attacks. Less than 100 mg/dL is the level of LDL cholesterol you want to have in your blood. In contrast, once the LDL cholesterol levels reach 160 mg/dL or higher, you have high cholesterol. Some types of foods and supplements lower LDL and leave good HDL cholesterol levels intact. Consider eating walnuts, cooking with more olive oil, consuming Metamucil and/or fish oil (Omega-3 fatty acids) every day. These things will help lower your LDL cholesterol.
