1.Control total calories and maintain normal weight Maintaining calorie balance, preventing obesity and making weight reach and maintain within the ideal range is one of the important links in the prevention and treatment of coronary heart disease. 2.Control fat and cholesterol High blood fat is one of the main causes of coronary heart disease. With the increased intake of meat, animal oil, high-fat dairy products, egg yolk and animal brain, excessive intake of saturated fatty acids and cholesterol is the main dietary factor leading to hyperlipidemia. Therefore, fat intake should be controlled so that the total fat intake accounts for less than 20%-25% of the total calories, of which animal fat should not exceed 1/3, and cholesterol intake should be controlled at less than 300 mg per day. 3. The quality and quantity of protein should be appropriate. The intake ratio of vegetable protein, especially soy protein, should be increased appropriately. The appropriate proportion of protein intake is: protein accounts for about 12% of total calories, of which high-quality protein accounts for 40% to 50%, and animal protein and vegetable protein each account for half of high-quality protein. 4. Adopt compound sugars and control the intake of monosaccharides and disaccharides By reducing the proportion of fat calories to total calories accordingly, the calories provided by compound sugars will be increased. Try to eat less pure sugar food and its products. The main source of sugar should be rice, flour, mixed grains and other starch-containing foods. 5, supply sufficient vitamins, inorganic salts and trace elements The diet should pay attention to eat more food containing magnesium, chromium, zinc, calcium, selenium elements. Magnesium-rich foods are millet, corn, beans and soy products, wolfberry, cinnamon, magnesium can affect lipid metabolism and thrombosis, promote fibrinolysis, inhibit coagulation or platelet stabilization, prevent platelet coagulation; chromium-rich foods, such as yeast, beef, liver, whole grains, cheese, brown sugar, chromium can increase the decomposition and excretion of cholesterol, trace chromium can prevent atherosclerosis Zinc-rich foods include meat, oysters, eggs, milk, scientists believe that the zinc-copper ratio can affect the content of serum cholesterol; calcium-rich foods include milk, soy products, seafood such as shrimp, etc. Recent studies have shown that the increase in dietary calcium content can prevent hypertension and hypercholesterolemia caused by high-fat diet; selenium-rich foods include oysters, fresh shellfish, shrimp, shrimp, prawns, etc. Selenium supplementation can resist atherosclerosis, reduce whole blood viscosity, increase coronary blood flow and reduce the degree of damage to the heart muscle. Eating more vegetables and fruits is good for the heart. Vegetables and fruits are indispensable foods in human diet, rich in vitamin C, inorganic salts, fiber and pectin. Where green vegetables or yellow fruits and vegetables contain more carotene, which has an antioxidant effect, vitamin C can affect myocardial metabolism, increase vascular toughness and make blood vessels more elastic, and large doses of vitamin C can make cholesterol oxidized to bile acid and excreted. Kiwi, citrus, lemon and purple-skinned eggplant are rich in vitamin C. More food containing more vitamin C should be eaten. 6, a small number of meals Avoid eating too much, too much, do not eat too greasy and salty food, the daily salt intake should be controlled at 3 to 5 grams. 7, avoid smoking, alcohol, drinking strong tea and avoid all spicy condiments.
