Coronary heart disease is one of the contemporary diseases that threaten human life and health, and is the leading cause of death among middle-aged and elderly people. Therefore, the prevention and treatment of coronary heart disease and the reduction of its morbidity and mortality have received attention from all over the world. The incidence of coronary heart disease, hypertension and hyperlipidemia in China is increasing year by year, which is severely affecting people’s life and health. 1, the basic causes 1, with the continuous improvement of living standards, people consume too much animal fat and food containing high cholestrol, such as animal offal, all kinds of meat, egg yolk, etc., so that the body cholestrol content increased. 2, employment, science and technology competition is increasing, resulting in some people’s mental tension, insomnia, fatigue. Due to mental tension use when the secretion function is disrupted, the blood catecholamines, adrenal glucagon levels increase, triggering hypertension, but also can cause fat metabolism rate disorder. The cycle of high blood pressure and high cholesterol level will further affect the coagulation mechanism and increase the aggregation of platelets; then cause the damage of coronary artery vessel wall, and the fat accumulation will produce atheromatous destruction, causing the narrowing of coronary artery lumen and the thickening and hardening of vessel intima, so that the heart blood supply is insufficient. The intake of fatty and cholesterol-rich foods should be controlled at less than 30% of total calories, the intake of animal protein should be controlled at less than 20-50%, and vegetable protein should be increased, and soy protein is recommended because it can lower cholesterol. 2.Carbohydrate intake should account for 60-70% of total calories, especially for obese people and people with high glycerol, and the proportion of complex carbohydrates should be increased, such as rice, potatoes, etc. 3, fruits and vegetables are rich in dietary fiber, can promote gastrointestinal motility, has the effect of lowering cholesterol. Prevent constipation, such as black fungus, onions, garlic, shiitake mushrooms, ginger seaweed, etc., all have different degrees of lipid-lowering effect, can dilate coronary arteries, hypotensive, diuretic, sedative is conducive to the prevention of coronary heart disease. 4, water and minerals: appropriate to increase the ratio of beneficial inorganic salts and trace elements, such as magnesium, calcium, manganese, copper, zinc, etc., can reduce the incidence of coronary heart disease. 5, condiments: salt, soy sauce reported intake and hypertension is directly proportional to the recommended daily intake of 3-5 grams of salt, soy sauce should not be too much application, MSG contains high sodium, hypertensive people should eat less is better, tea has the effect of reducing bile solids, beneficial to the prevention of atherosclerosis. 6, the necessary physical exercise, establish a correct outlook on life, world view, values, should be anger, avoiding searched, remove worries, optimistic and happy, work and rest, conducive to the prevention of coronary heart disease. Third, the prevention of general drugs 1, vitamins: such as vitamin b1, b6, c, pp, e, a to improve fat metabolism and prevention of atherosclerosis, myocardial infarction has a certain effect. 2, compound Danshen tablets, blood lipid Kang, aspirin enteric dissolved tablets, etc., all have the expansion of cardiovascular and cerebrovascular dredging and softening of blood vessels, reduce blood lipids, blood viscosity, clean blood and atherosclerotic plaque thrombosis, effective prevention of coronary heart disease, hypertension, high blood pressure, reduce the incidence. There are many causes of coronary heart disease, but at home and abroad, hypertension, hyperlipidemia, hyperglycemia and obesity are considered to be the main factors. All these causes are closely related to diet and living environment. Therefore, it is crucial to develop good living habits and pay attention to adjusting dietary structure in daily life to prevent this disease. Perform the necessary physical exercise, adhere to more than 30 minutes of exercise or health exercises every day, improve their own cultivation, establish a correct outlook on life, and deal with all kinds of conflicts in accordance with the laws and inevitability of career development, which is conducive to health. The methods described above are easy to implement and economical. It is necessary to actively promote them and raise the awareness of group prevention, then we can reduce the incidence of coronary heart disease and guarantee the gradual improvement of the health level of middle-aged and elderly people.
