To prevent the occurrence of coronary heart disease and control the development of coronary heart disease, we must “keep our mouths shut and our legs open”. Keep your mouth shut is to “keep” the disease from the mouth “off, because bad eating habits and unreasonable dietary structure and the development of coronary heart disease is closely related. So, how to arrange the diet of coronary heart disease patients reasonably? 1.Individualized diet. Reasonable diet should meet the general nutritional health requirements, but also pay attention to the principle of individualization. (1) The overall caloric intake should not be too much, and the total daily calorie intake should be controlled at 6694.4~8368 kJ (1600~2000 kcal). (2) In terms of the composition of nutrients in the diet, the total amount of protein should not be too much. Generally, 60 to 70 g per day is appropriate, accounting for 12% to 15% of the total calories, but a sufficient amount of high-quality protein should be supplied. (3) Avoid too much sweet food, especially sucrose and fructose. (4) Low-fat diet, daily fat intake is controlled at about 50 g, accounting for 20% to 25% of total calories. (5) Low salt diet, avoid salty food, increase calcium, vitamins, fiber and water appropriately. (6) Do not overeat. 2, it is appropriate to eat grains and cereals coronary heart disease patients should control the calories in the diet, limit excessive sugar, but this does not mean that patients with coronary heart disease should take “starvation therapy”. From a nutritional point of view, the body should increase the protein and vitamins, so that the body to achieve nutritional balance. High doses of vitamin PP can lower serum cholesterol concentrations. High doses of vitamin C can lower cholesterol, improve coronary circulation, and reduce vascular disease caused by high-fat diets. Vitamin PP and vitamin C are widely distributed in natural foods, such as the outer skin and germ of cereals, yeast, peanuts, beans, fresh vegetables and fruits. In addition, dietary fiber in food has a certain therapeutic effect on patients with coronary heart disease. The intake of certain fiber can block the enterohepatic circulation of bile acids, reduce the concentration of bile and blood cholesterol, and has a good effect on the prevention and treatment of atherosclerosis. Dietary fiber is widely present in coarse grains, legumes, vegetables and fruits. 3, limit salt intake is too high salt intake is a high risk factor for hypertension, hypertension is one of the risk factors for coronary heart disease. A significant proportion of patients with coronary heart disease suffer from hypertension, and hypertension has the role of promoting the occurrence and development of coronary heart disease. Therefore, it is important to control hypertension and try to lower the blood pressure level for the prevention and treatment of coronary heart disease. For those who already have hypertension, salt restriction can be used as a non-pharmacological treatment. People with hypertension and a family history of hypertension should limit salt to 2-5 g per day, and those with coronary artery disease and hypertension should gradually limit the amount of salt they eat so that their tastes gradually become accustomed to low-salt meals. Salt can be sprinkled on the food before cooking so that the salt taste can be clearly felt; you can also use sugar, vinegar, spices and other seasonings to increase the taste of food to reduce the amount of salt. The use of commercially available low-sodium salt is also a good way to limit salt. 4, do not promote “vegetarianism”. In order to be healthy, we must consume adequate nutrition every day, including protein, fat, vitamins, inorganic salts, water and fiber. These nutrients are obtained from the diet. Many patients with coronary heart disease promote a vegetarian diet, believing that only a vegetarian diet will not lead to an increase in blood lipids and will not aggravate coronary heart disease. However, a long-term vegetarian diet can easily lead to a lack of certain essential amino acids, vitamins and trace elements, which is also detrimental to patients with coronary heart disease. Patients with coronary heart disease should not be completely vegetarian, but should reasonably match the diet to ensure that the body adequate nutrition. 5, should not be full meal too full meal can increase myocardial oxygen consumption, increase the burden on the heart, induce or aggravate angina, easy to induce acute myocardial infarction or sudden death. 6, should not drink alcohol can make the blood pressure rise, long-term drinkers increased incidence of hypertension, cerebrovascular accidents, and drinking alcohol will increase the resistance of the basic drugs to lower blood pressure. Advocate hypertensive patients to quit drinking, and those who have the habit of drinking alcohol must limit alcohol. If you have coronary heart disease and arteriosclerosis, do not drink more liquor. If you have coronary heart disease, do not drink more beer for a long time. Studies have shown that frequent consumption of large amounts of beer can lead to fatty deposits in the heart muscle tissue, myocardial hypertrophy, heart enlargement. As for the folklore that a small amount of red wine is good for the heart, there is no reliable clinical research evidence to support the amount of alcohol consumption is also difficult to control, so it is recommended that try not to drink alcohol, including red wine. 7, avoid smoking the incidence of coronary heart disease and death rate of smokers is 2 to 6 times that of non-smokers, and with the number of daily smoking is positively correlated. 8, food taboos: (1) animal offal, fish roe, crab yolk, egg yolk and other foods with high cholesterol content. (2) fatty meat: fat content of up to 90.8%, easy to make the body excess fat accumulation, lipid elevation, leading to atherosclerosis.
