I should be concerned about my child's blood cholesterol levels:


A. If I have angina

B. If my great aunt has high cholesterol

C. If my brother has a heart-valve defect

D. There is no need to
A. If I have angina. Children from families in which a parent or grandparent has developed heart disease, which includes a heart attack or the chest pain of angina, at an early age (before age 55 in father or grandfather, or before age 65 in mother or grandmother) should have their cholesterol levels tested.
To reduce high blood cholesterol, one should:


A. Follow a diet low in saturated fat and low in cholesterol

B. Be more physically active

C. Lose weight if overweight

D. All of the above
D. All of the above. Following a Step II Diet (low saturated fat, low cholesterol), being more physically active, maintaining a healthy weight and taking cholesterol-lowering medication, if prescribed, are all important to help you lower your blood cholesterol level and reduce your chance of heart attack or other heart disease.
Which food does not have a lot of saturated fat?


A. Coconut oil

B. Whole milk

C. Chicken, with skin

D. Whole wheat bread
D. Whole wheat bread. The other choices are all high in saturated fat. Foods high in saturated fat include foods from animals, such as fatty cuts of meat, poultry with the skin, whole-milk dairy products and lard. Even though they are vegetable products, tropical oils like coconut, palm kernel and palm oils are also high in saturated fat.
Which food does not have a lot of cholesterol?


A. Steak

B. Banana

C. Shrimp

D. Butter
B. Banana. Dietary cholesterol also can raise your blood cholesterol level, although usually not as much as saturated fat. So it is also important to choose foods low in dietary cholesterol as well as saturated fat. Dietary cholesterol is found only in foods that come from animals. Many of these foods also are high in saturated fat.
My LDL-cholesterol goal is:


A. Less than 200 mg/dl

B. 100 to 130 mg/dl

C. Less than 100 mg/dl

D. It depends on my heart health
D. It depends on my heart health. For the general population, a level of LDL-cholesterol below 130 mg/dl is desirable. But if you already have heart disease, your goal is lower -- less than 100 mg/dl. This is because patients with heart disease, even if they have relatively low cholesterol levels (say an LDL-cholesterol of 120 mg/dl), are more likely to have a heart attack or other heart disease complications.
The best type of fat to eat is:


A. Polyunsaturated fat

B. Monounsaturated fat

C. Unsaturated fat

D. All of the above
D. All of the above. Your body needs fat for a variety of functions, so not all dietary fat is bad. However, it is true that some fats are better than others. Look for fats and oils that are unsaturated -- either polyunsaturated (safflower, sunflower, corn and soybean oils) or monounsaturated (olive and canola oils). Unsaturated fats help to lower blood cholesterol when they are substituted for saturated fat. Just be sure to limit the total amount of fats or oils, since even those that are unsaturated are a rich source of calories.
