Answers to the Cholesterol and Heart Disease I.Q. Quiz

1. True. High blood cholesterol is one ofthe risk factors for heart disease that a person can do something about. High bloodpressure, cigarette smoking, diabetes, overweight, and physicalinactivity are the others.
2. False. Although some red meat ishigh in saturated fat and cholesterol, which can raise your blood cholesterol, you do notneed to stop eating it or any other single food. Red meat is animportant source of protein, iron, and other vitamins and minerals.You should, however, cut back on the amount of saturated fat andcholesterol that you eat. One way to do this is by choosing leancuts of meat with the fat trimmed. Another way is to watch yourportion sizes and eat no more than 6 ounces of meat a day. Sixounces is about the size of two decks of playing cards.
3. False. A total blood cholesterol levelof under 200 mg/dL is desirable and usually puts you at a lower risk for heart disease. A blood cholesterol level of 240 mg/dL is high and increases yourrisk of heart disease. If your cholesterol level is high, yourdoctor will want to check your level of LDL-cholesterol ("bad"cholesterol). A HIGH level of LDL-cholesterol increases your riskof heart disease, as does a LOW level of HDL-cholesterol ("good"cholesterol). An HDL-cholesterol level below 35 mg/dL isconsidered a risk factor for heart disease. A total cholesterollevel of 200-239 mg/dL is considered borderline-high and usuallyincreases your risk for heart disease. All adults 20 years of ageor older should have their blood cholesterol level checked at leastonce every 5 years.
4. False. Fish oils are a source ofomega-3 fatty acids, which are a type of polyunsaturated fat. Fish oil supplements generally donot reduce blood cholesterol levels. Also, the effect of thelong-term use of fish oil supplements is not known. However, fishis a good food choice because it is low in saturated fat.
5. True. Eating less fat, especiallysaturated fat, and cholesterol can lower your blood cholesterol level. Generally yourblood cholesterol level should begin to drop a few weeks after youstart on a cholesterol-lowering diet. How much your level dropsdepends on the amounts of saturated fat and cholesterol you used toeat, how high your blood cholesterol is, how much weight you loseif you are overweight, and how your body responds to the changesyou make. Over time, you may reduce your blood cholesterol levelby 10-50 mg/dL or even more.
6. True. Saturated fats raise your bloodcholesterol level more than anything else. So, the best way to reduce yourcholesterol level is to cut back on the amount of saturatedfats that you eat. These fats are found in largest amounts inanimal products such as butter, cheese, whole milk, ice cream,cream, and fatty meats. They are also found in some vegetableoils--coconut, palm, and palm kernel oils.
7. False. Most vegetable oils--canola,corn, olive, safflower, soybean, and sunflower oils--contain mostly monounsaturated andpolyunsaturated fats, which help lower blood cholesterol when usedin place of saturated fats. However, a few vegetable oils--coconut, palm, and palm kernel oils--contain more saturated fatthan unsaturated fat. A special kind of fat, called "trans fat,"is formed when vegetable oil is hardened to become margarine orshortening, through a process called "hydrogenation." The harder the margarine or shortening, the more likely it is tocontain more trans fat. Choose margarine containing liquidvegetable oil as the first ingredient. Just be sure to limit thetotal amount of any fats or oils, since even those that areunsaturated are rich sources of calories. 
8. True. People who have had one heartattack are at much higher risk for a second attack. Reducing blood cholesterol levels cangreatly slow down (and, in some people, even reverse) the buildupof cholesterol and fat in the wall of the coronary arteries andsignificantly reduce the chances of a second heart attack. If youhave had a heart attack or have coronary heart disease, your LDL levelshould be around 100 mg/dL which is even lower than the recommendedlevel of less than 130 mg/dL for the general population.
9. False. Children from "high risk"families, in which a parent has high blood cholesterol (240 mg/dL or above) or in which aparent or grandparent has had heart disease at an early age (at 55years or younger), should have their cholesterol levels tested. Ifa child from such a family has a cholesterol level that is high, itshould be lowered under medical supervision, primarily with diet,to reduce the risk of developing heart disease as an adult. Formost children, who are not from high-risk families, the best way toreduce the risk of adult heart disease is to follow a low saturatedfat, low cholesterol eating pattern. All children over the age of2 years and all adults should adopt a heart healthy eating patternas a principal way of reducing coronary heart disease. 
10. False. Blood cholesterol levels inboth men and women begin to go up around age 20. Women before menopause have levelsthatare lower than men of the same age. After menopause, a women'sLDL-cholesterol level goes up--and so her risk for heart diseaseincreases. For both men and women, heart disease is the number one cause of death.
11. True. Food labels have beenchanged. Look on the nutrition label for the amount of saturated fat, total fat, cholesterol, andtotal calories in a serving of the product. Use this informationto compare similar products. Also, look for the list ofingredients. Here, the ingredient in the greatest amount is firstand the ingredient in the least amount is last. So to choose foodslow in saturated fat or total fat, go easy on products that listfats or oil first, or that list many fat and oil ingredients.
