There's a lot of information about cholesterol in the news, and with good reason. High cholesterol contributes to heart disease. Heart disease kills more Americans than all cancers combined.
Cholesterol is a waxy, fatlike substance that your body – mostly the liver – makes. Cholesterol is used to make some hormones, vitamin D, and bile acids. These help to digest fat. Cholesterol also is used to build healthy cell membranes (walls) in the brain, nerves, muscles, skin, liver, intestines, and heart. It only takes a small amount of cholesterol to meet all these needs. Your body makes enough. You don’t need any extra cholesterol from your diet.
Cholesterol causes a problem only when you have too much of it in your blood. Excess cholesterol is deposited in the lining of the arteries. This includes the arteries that feed your heart muscle. This narrows the inside of the arteries, through which blood flows. High blood cholesterol does not cause symptoms, so many people are unaware that their cholesterol levels are too high.
You should have your cholesterol checked at least every 5 years, starting at age 20. The most accurate test is a lipoprotein profile or lipid panel, a group of blood tests given after fasting for 9 to 12 hours. The results show:
Your total cholesterol
Your LDL ("bad") cholesterol. This is what's deposited in your arteries
Your HDL ("good") cholesterol. This helps keep cholesterol from building up in your arteries
Your triglycerides. These are another form of fat in your blood
Even without a lipoprotein profile, you can get a rough idea of your cholesterol health if you know your total cholesterol and HDL cholesterol. These levels can be determined through a nonfasting cholesterol test often given at shopping malls or health fairs. Talk with your health care provider about your total cholesterol, HDL and LDL levels.
The higher your HDL cholesterol, the better. The HDL cholesterol helps protect against heart disease. You can increase your HDL levels by losing weight, if needed, exercising, and quitting smoking.
Having a high level of LDL cholesterol can cause fatty plaque to stick to the insides of your artery walls. The arteries get narrower and stiffer. This means less blood can flow through them. This process, called atherosclerosis, develops over a long time. It is especially dangerous if it narrows the arteries to the heart or brain. This creates a major risk for heart attack and stroke. Build-up of cholesterol in the arteries of the legs can cause leg pain and trouble walking, and other serious problems.
Heredity, or what you inherit from your parents, is the main factor determining your cholesterol levels. Your diet is the second risk factor for high cholesterol. Foods containing cholesterol, saturated fats, or trans fats all contribute to your cholesterol levels.
Many foods that come from animals are high in both saturated fat and cholesterol. Some nonanimal foods also are high in saturated fat. Foods with coconut and palm oils, trans fats, and hydrogenated vegetable oils like shortening and margarine raise cholesterol.
These are other factors that influence your cholesterol levels:
Weight. Being overweight usually raises your LDL cholesterol. Losing weight may lower your LDL level and triglycerides, and boost your HDL cholesterol.
Exercise. Getting regular exercise may lower your LDL cholesterol and raise your HDL cholesterol.
Age and gender. Until menopause, women usually have lower total cholesterol levels than men. After age 50, women often have higher total cholesterol levels than men of the same age. For both men and women, total cholesterol levels rise until about age 65.
Alcohol. Although alcohol boosts HDL cholesterol, it has no effect on LDL cholesterol, and drinking too much alcohol raises triglycerides. Too much alcohol also damages the liver, brain, and heart.
Smoking. If you smoke, giving up tobacco will increase HDL levels.
The main goal of treatment that lowers cholesterol is to lower your LDL level enough to reduce your risk for developing heart disease or having a heart attack. The higher your risk, the lower your LDL goal will be.
A heart-healthy diet means eating fewer foods high in saturated fats. These foods include fried foods, red meat, processed meats (cold cuts and hot dogs), some cheeses, and most commercially prepared baked goods (muffins, cookies, doughnuts). Manufacturers are reducing saturated fats and trans fats in their products. Make sure you check nutrition labels and choose those with the least amount of saturated and trans fats.
A diet low in both saturated fat and cholesterol has less than 7% of calories from saturated fat and less than 200 mg of cholesterol per day. There should only be enough calories to maintain a healthy weight and to avoid weight gain. You might also increase the amount of fiber in your diet.
Fish is also a good choice. Many types contain high levels of omega-3 fatty acids. These may help lower blood cholesterol, blood pressure, and reduce your risk for blood clots. Salmon, tuna, and herring, contain the most omega-3s.
You should also eat more vegetables, fruit, and whole grains like oatmeal and barley.
If you eat red meat, here are some ways to decrease fat without giving up flavor:
Decrease the amount of meat in recipes.
Have smaller portions of meat and add more vegetables, grains, and fruit to a meal.
Select lean cuts when you buy meat. The terms "round" and "loin" indicate lower fat.
Trim off fat from meat before cooking.
If you need help with your diet, talk with you health care provider about seeing a dietician or nutritionist.
Exercise. Regular physical activity – 30 to 60 minutes on most, if not all days – is recommended for everyone. It can help raise HDL and lower LDL cholesterol. For adults, the CDC recommends 150 minutes of moderate aerobic exercise every week and exercises to strengthen muscles on 2 or more days a week.
Maintain a healthy weight. Losing weight if you are overweight can lower your LDL cholesterol and raise your HDL cholesterol.
Control your blood pressure. Make sure you get it checked when you have appointments.
Consider medications. If your cholesterol level remains high 6 months after you change your lifestyle, ask your health care provider about medications that can lower your cholesterol.
