The correct answer is all of the above. The test measures the level of these fats, or lipids, in your blood. Cholesterol is found in all parts of the body. Your body needs a little bit of cholesterol. But too much cholesterol can clog your arteries and lead to heart disease and stroke. Some cholesterol is considered "good" (HDL) and some is considered "bad." (LDL)

The correct answer is false. When you have too much LDL, or "bad," cholesterol in your blood, it can build up on artery walls, causing them to become hard and narrow. The lower your LDL, the lower your risk for heart disease. Ask your doctor what your LDL level should be.

The correct answer is HDL. HDL helps remove LDL cholesterol from artery walls. HDL levels of 60 mg/dL or above helps protect you from heart disease. HDL below 40 mg/dL for men and below 50 mg/dL for women can increase your risk for heart disease.

The correct answer is all of the above. When plaque builds up on your artery walls, blood clots can form that block blood flow to the heart or brain, causing a heart attack or stroke. Talk with your doctor about how you can lower your risk for heart disease.

The correct answer is false. Improving your health habits can lower cholesterol and triglyceride levels. Sometimes, lifestyle changes alone aren't enough, so your doctor may prescribe medicine.

The correct answer is all of the above. Family history, diabetes, and other medical problems also increase your risk. Ask your doctor about healthy changes you can make to help lower high cholesterol.

The correct answer is true. To lose about one pound a week, eat about 500 fewer calories a day. You can lose weight by eating smaller portions. Also replace low-fiber, high-fat foods with lean meats and other proteins, whole grains, low-fat dairy products, and plenty of fruits and vegetables.

The correct answer is true. Exercising 30 minutes a day at least 5 days a week can increase HDL levels by about 5 percent. If you haven't been active, check with your doctor before starting to exercise. Start by walking just a few minutes several times a week. Build up to 30 minutes of brisk exercise 5 days a week.

The correct answer is monounsaturated and polyunsaturated fats. They are found in fish, nuts, seeds, avocados, and olive, canola, corn, soy, and sunflower oils. Replacing saturated and trans fats with these healthy fats helps lower LDL and increase HDL. Omega-3s from fish help lower high triglycerides.

The correct answer is all of the above. Quitting isn't easy, but keep in mind that the more times you attempt to quit, the more likely you are to be successful.
