KNOW YOUR NUMBERS
Knowing your cholesterol, glucose and blood pressure numbers goes a long way to maintaining your health and reducing your risk of heart disease and stroke. CHOLESTEROL Cholesterol is a fatty substance that’s found in animal-based foods such as meats, poultry, egg yolks, and whole milks. Do you know the other type of fat that is found in animal-based products? That’s right — saturated fat. So, when you follow the tips to reduce your saturated fat intake, in most cases, you will be reducing your dietary cholesterol intake at the same time. For example, if you switch to low-fat and fat-free dairy products, you will reduce your intake of both saturated fat and cholesterol. Total Cholesterol — This is the total measured cholesterol in your blood. This number includes all other types of cholesterol such as HDL and LDL, as defined below. High blood cholesterol can increase your risk of heart disease. It is important to know your numbers — You can’t tell if the cholesterol in your blood is high by how you feel. You’ll need a blood test from your healthcare provider to know. If you don’t know what your blood cholesterol level is, talk to your health care provider. HDL — HDL stands for high-density lipoprotein cholesterol. The HDL cholesterol is often called “good” cholesterol because it helps carry cholesterol away from your body’s organs and to your liver where it can be removed. To help you remember, that HDL is the “good” cholesterol, recall that the “H” stands for high and higher HDL cholesterol is good.
THE RECOMMENDATION The Dietary Guidelines for Americans 2010 recommend that individuals consume less than 300 milligrams (mg) of cholesterol each day.

LDL — LDL stands low-density lipoprotein cholesterol. The LDL cholesterol is sometimes called “bad” cholesterol because it’s the type of cholesterol that is linked with a higher chance of heart disease. Remember that L stands for “low” and you want to keep LDL lower in your blood.
Too much cholesterol in the blood, or high blood cholesterol, can be serious. People with high blood cholesterol have a greater chance of getting heart disease. Cholesterol can build up on the walls of your arteries (blood vessels that carry blood from the heart to other parts of the body). This buildup of cholesterol is called plaque. Over time, plaque can cause narrowing of the arteries. Triglycerides — This is a type of fat found in your blood. Too much of this type of fat may raise the risk of coronary artery disease, especially in women. A blood test measures your triglycerides along with your cholesterol. Normal triglyceride levels are below 150. Levels above 200 are high. Factors that can raise your triglyceride level include — • Being overweight • A very high carbohydrate diet • Lack of physical activity • Certain diseases and medicines • Smoking • Some genetic disorders • Excessive alcohol use You may be able to lower your triglycerides with a combination of losing weight, diet, and exercise. You also may need to take medicine to lower your triglycerides.
BLOOD SUGAR (GLUCOSE) Blood sugar, or glucose, is the main sugar found in your blood. It comes from the food you eat, and is your body’s main source of energy. Your blood carries glucose to all of your body’s cells to use for energy. Diabetes is a disease in which your blood sugar levels are too high. Over time, having too much glucose in your blood can cause serious problems. Even if you don’t have diabetes, sometimes you may have problems with blood sugar that is too low or too high. Keeping a regular schedule of eating, activity, and taking any medicines you need can help. If you do have diabetes, it is very important to keep your blood sugar numbers in your target range. You may need to check your blood sugar several times each day. Your health care provider will also do a blood test called an A1C. It checks your average blood sugar level over the past three months. If your blood sugar is too high, you may need to take medicines and/or follow a special diet. Having diabetes or prediabetes puts you at increased risk for heart disease and stroke. You can lower your risk by keeping your blood glucose, blood pressure, and blood cholesterol close to the recommended target numbers—the levels suggested by diabetes experts for good health. Reaching your targets also can help prevent narrowing or blockage of the blood vessels in your legs, a condition called peripheral arterial disease. If you have diabetes, you are at least twice as likely as someone who does not have diabetes to have heart disease or a stroke. People with diabetes also tend to develop heart disease or have strokes at an earlier age than other people. If you are middle-aged and have type 2 diabetes, some studies suggest that your chance of having a heart attack is as high as someone without diabetes who has already had one heart attack. In addition, heart attacks in people with diabetes are more serious and more likely to result in death.
