The manifestation of atherosclerosis is mainly determined by the degree of vascular lesions and ischemia of the affected organs. For patients with early-stage atherosclerosis, most of them have almost no clinical symptoms and are in an insidious state of latent development. For patients with middle stage atherosclerosis, most of them have more or less clinical symptoms such as palpitations, chest pain, chest tightness, headache, dizziness, cool and numb limbs, sore and lazy limbs, claudication, reduced vision, memory loss, insomnia and dreaminess, etc. Different patients will have different symptoms. So, how to prevent arteriosclerosis? 1, limit the intake of food cholesterol: lowering LDL cholesterol and total cholesterol is the key to prevent and treat atherosclerosis. Although not all cholesterol in the body comes from food, limiting cholesterol intake is necessary to reduce hypercholesterolemia. Foods rich in cholesterol are egg yolks, crab yolks and various animal offal, which should be eaten sparingly. For example, one egg yolk contains about 200~300mg of cholesterol, which is the maximum daily cholesterol intake. The former mainly contains saturated fatty acids, the intake of which can raise cholesterol and should be strictly limited so that it does not exceed 7% of the total daily calories. Although the latter is unsaturated fatty acids, it should also be appropriately limited to no more than 20-25g per day because of its high caloric value. All fat calories should not exceed 30% of the total calorie intake. Advocate scientific cooking methods, dishes mainly steamed, boiled and cold, less oil in stir-fry, as far as possible not to fry or deep-fry food, and less margarine food. 3.Limit the total calorie intake: In addition to limiting fat, carbohydrates, which provide calories, should also be appropriately limited, that is, the daily staple food should be controlled, so that each meal is not full, and eat more coarse grains (such as whole wheat flour, etc.), mixed grains (such as beans and noodles, etc.) and fresh green leafy vegetables, which are rich in dietary fiber and vitamins and low in calories. If the dyslipidemia is combined with or secondary to diabetes, its staple food control is even more important. 4, quit smoking and limit alcohol: smoking can inhibit the activity of lipoprotein lipase (an important enzyme involved in lipoprotein metabolism in human body), make triglycerides rise and high-density lipoprotein cholesterol fall, also can destroy the function of endothelial cells and cause arterial spasm. So for patients with dyslipidemia and atherosclerosis is very harmful, must quit smoking. And moderate drinking, especially wine, for the prevention and control of atherosclerosis may be beneficial, to no more than 100g of wine per day is appropriate. 5, choose appropriate physical exercise: for overweight and obese people, in addition to diet control, physical exercise is an effective weight loss measure. Centripetal obesity characterized by increased waist circumference, increased visceral fat, prone to insulin resistance and metabolic syndrome, many patients with dyslipidemia combined with fatty liver, more should achieve the effect of fat consumption and weight loss through physical exercise. Physical exercise is recommended to use low and medium intensity rhythmic and repetitive aerobic exercise, such as walking, swimming, cycling, tai chi or gymnastics, such as walking for 30 minutes a day with a distance of 3000 meters.
