As people’s living standards continue to improve and their dietary structure changes, the richer their diet, the more high cholesterol and high fat foods they consume, which contributes to the increasing incidence of the common and prevalent hyperlipidemia year by year. Hypercholesterolemia is the most common type of hyperlipidemia. Lifestyle improvement is the basis of cholesterol-lowering treatment, and cholesterol can be reduced by 7 to 9 percent through dietary control and exercise. Even if you are already taking cholesterol-lowering medications, you still need to adhere to lifestyle changes. Focusing on medications without focusing on diet control and exercise can make it difficult to keep cholesterol below target values in the long term. At present, there are “four magic words” for improving the lifestyle of patients with hypercholesterolemia: reasonable diet, moderate exercise, weight control, and quitting smoking and limiting alcohol. 1.Rational diet Control total calories: 4 taels (female) and 6 taels (male) of staple food per day, with whole wheat bread, oats, rice, potatoes and pumpkin as the best, less snacks and no fried food. Reduce the intake of saturated fatty acids: eat less animal fat, paying particular attention to hidden animal fat such as sausage and pork ribs within the fat. Use <25 grams of oil per person per day for cooking. Increase the intake of unsaturated fatty acids: eat fish twice a week, and use olive oil or tea seed oil instead of other cooking oils when available. Control the intake of cholesterol: daily cholesterol intake should be <200 mg. Should try not to eat animal offal, reduce fatty meat foods, egg yolk no more than 2 times a week, and it is recommended to replace whole milk with skim milk. Eat more vegetables (1 pound per day), fruits (1-2) and soy products. Regular physical exercise can help control weight, lower "bad" cholesterol (LDL-C) and raise "good" cholesterol (HDL-C). Patients with hypercholesterolemia should engage in moderate intensity physical activity 3-5 times per week for 30-45 minutes each time. Suitable exercises include brisk walking or jogging, swimming, mountain climbing, table tennis, badminton, tai chi, bicycling, etc. The intensity of the exercise should not exceed the heart rate. The intensity of the exercise is appropriate with a heart rate of no more than (170-age). It can be summarized as aerobic exercise "one, three, five, seven": at least once a day, at least 30 minutes each time, at least 5 days a week, heart rate below (170 - age) times/minute during exercise. Precautions for exercise in patients with hypercholesterolemia combined with coronary artery disease: Do not exercise in the early morning, which is a high incidence time for cardiovascular events. Limit your exercise to a maximum heart rate of 100-120 beats per minute. The following conditions should not be exercised: frequent attacks of angina or attacks even at rest; obvious arrhythmias; combined heart failure or severe hypertension. 3. Weight control Avoid high-fat and high-cholesterol foods, such as fatty meat, animal offal, butter, etc. Pay attention to invisible fats, such as sausages and ribs. Avoid excessive intake of sugar, drinks and snacks. Pay attention to the calorie content of snacks, such as eating two extra handfuls of peanuts a day will add 1.3 pounds of fat in a week; eating 2 extra sunflower seeds is equivalent to eating 4 extra taels of rice. Avoid fast food, French fries, fried chicken, ice cream, hamburgers all contain a surprising amount of calories. Eat more vegetables, coarse grains and fruits. Change the cooking method, eat more steamed, boiled and mixed, and avoid fried foods. Adhere to regular exercise. 4, quit smoking and limit alcohol A large number of studies have confirmed that smoking can cause vascular endothelial dysfunction, enhanced inflammatory response, increased thrombosis, thus promoting or aggravating the progression of cardiovascular disease. Smoking can further aggravate atherosclerosis in patients with hypercholesterolemia and increase the risk of acute myocardial infarction, stroke, sudden cardiac death and other serious complications. Therefore, it is important for all patients with hypercholesterolemia and heart disease to quit smoking. There is no conclusive evidence on whether low to moderate alcohol consumption is beneficial in preventing heart disease. It is generally accepted that patients with hypercholesterolemia need to avoid drinking large amounts of alcohol, no more than 2 taels of wine per day, no more than 1 tael of white wine per day, and no more than 300 ml of beer per day, and the less alcohol consumed the better.
