2、f cholesterol in the blood is an important risk factor for heart disease.Some people say that the danger of heart disease is exaggerated.

3、e with heart disease suffer chest pains that make simple activities, such as walking, shaving, or taking a shower, difficult.Research has proven that cholesterol levels are connected with heart disease.

4、ers have found that the people who have high levels of cholesterol have more heart attacks.A natural substance in the blood, cholesterol comes from the liver.

7、ke.What is a safe level of cholesterol? Adults have a high risk of heart attack if their cholesterol level is above 240 milligrams per deciliter (1/10 公升) of blood. Below-200 is better.

8、half of American adults have cholesterol levels above 200.To lower our cholesterol level, we must change our eating habits.

9、 than 30 percent of our diet. Blood cholesterol levels start to fall after 2 to 3 weeks of following a low-cholesterol, low-fat diet.

10、 much as 40 percent through changes in diet and amount of exercise.We must educate everyone, including children in elementary schools.

14、rains and vegetables. Avoid egg yolks (the yellow-part of the egg). Eat potatoes, beans, low-fat vegetables, and fruit. People often complain about low-fat diets before they have had time to get used to them. Food can taste good without cream, butter, and salt. You can use olive oil, mustard, fresh
15、herbs, or yogurt instead.A new diet can cause general anxiety, when people feel worded and nervous about what is going to happen. They must learn to deal with the changes in their lives.
