Coronary atherosclerotic heart disease mainly includes angina pectoris, myocardial infarction, etc. The causes of these diseases are complex, and once the disease is developed, the recovery is slow, and the disease becomes chronic, facing lifelong drug treatment, and if the treatment and care are not appropriate, it is easy to relapse, with a high disability and mortality rate. People often say that the three high mainly include high blood pressure, high blood pressure, high blood sugar. Increased blood pressure increases the risk of cardiovascular atherosclerosis, while elevated blood glucose and elevated lipids cause slow blood flow, decreased elasticity of the arteries, and the formation of atherosclerosis, and the arterial network supplying blood to the heart is attacked by the “three highs”, eventually leading to “paralysis “and cause the occurrence of coronary heart disease. That in life how to control the three highs through diet? One, a strict low-salt diet, control sodium intake The composition of salt is sodium chloride, long-term sodium intake will reduce the elasticity of the arterial wall, so that people suffer from hypertension. A study found that simply reducing salt can make 1/3 of patients’ blood pressure lower. A person needs only about 1 gram of sodium a day (unless a lot of sweating), 1 gram of salt is only about the size of a little peanut rice, while people in the daily diet intake is often several times or even dozens of times higher. Our residents’ sodium intake is significantly higher than the current WHO recommendation of less than 6g per day, while potassium intake is seriously inadequate, high potassium diet can promote the excretion of sodium in the body, while magnesium has the effect of lowering cholesterol and expanding blood pressure, adequate calcium intake can avoid the lack of calcium caused by bone calcium leaching and calcium in soft tissue, abnormal deposition of blood vessel walls. It is thus clear that maintaining a balance of inorganic elements such as sodium, potassium, magnesium and calcium in the diet and consuming foods with low salt, high potassium, high calcium and high magnesium can prevent hypertension and atherosclerosis, thus preventing coronary heart disease. Therefore, all hypertensive patients should take various measures to reduce the intake of sodium salt and increase the intake of potassium salt in food as much as possible. The main measures include: (1) reducing the salt used for cooking as much as possible, it is recommended to use a rationable salt spoon; (2) reducing the amount of sodium-containing condiments such as MSG and soy sauce; (3) eating less or no processed foods with high sodium content, such as salted vegetables, ham, sausages and all kinds of fried foods; (4) increasing the intake of vegetables and fruits; (5) using potassium-containing cooking salt for those with good kidney function. Strict control of low-salt diet can reduce blood pressure by 2-8 mmHg. Second, a strict low-fat diet, reduce fat intake Low-fat, low-cholesterol diet is necessary for the treatment of “three highs” and the prevention of coronary heart disease. However, it should be done in moderation to avoid overkill, especially for the elderly. Many elderly patients believe that animal fat is harmful and therefore rarely eat animal meat, and animal offal and egg yolk are also rejected because of their high cholesterol content. However, animal proteins contain more methionine, lysine, proline and taurine than vegetable proteins, and are recognized by the nutritional community as high-quality proteins, and long-term refusal may result in inadequate amino acid intake and decreased vascular fragility and elasticity. It is undeniable that the cholesterol content of animal livers and egg yolks is indeed very high and it is not suitable for people with dyslipidemia to eat them freely, but at the same time they rank high in nutritional value among common foods, such as egg yolks which are rich in lecithin and livers which are rich in vitamins A, D, B and trace elements, etc. It is a pity to give them up completely, but food in moderation helps to balance nutrition. There are many surveys and studies have shown that a vegetarian diet does not help to reduce the risk of coronary heart disease. Third, the diet is appropriate, balanced nutrition is the hard truth to prevent the occurrence of coronary heart disease, but easier said than done when not simple. For example, many people know that not eating breakfast is not conducive to health, but it has been so for years; in terms of drinking, people have different attitudes, either good drinking greedy cups can not own, or simply do not drip wine, however, various studies have shown that red wine and green tea, as well as containing polyphenols, which is a good thing to maintain the elasticity of the blood vessel wall, prevent atherosclerosis, there are trials show that drinking a glass of red wine every day Some trials have shown that drinking a glass of red wine a day can prevent the formation of blood clots and produce a protective effect similar to that of aspirin, so people can get it by drinking small amounts of red wine and moderate amounts of tea. In addition, people should also pay attention to the nutritional differences caused by the seasons and changes in production, for example, in winter, the peak of the onset of coronary heart disease, and people’s food in winter is often more lack of fresh fruits and vegetables rich in vitamin C, vitamin C has antioxidant properties, can reduce the concentration of fibrinogen in the blood, has a protective effect on the cardiovascular and cerebrovascular, a person try to maintain a daily consumption of vegetables at least 500 grams A person should try to maintain a daily vegetable consumption of not less than 500 grams, vitamin C intake of not less than 100 mg will help prevent the occurrence of coronary heart disease, especially hypertension and diabetes patients should do this. The development of atherosclerotic cardiovascular diseases caused by the “three highs” should not be ignored, and a healthy diet can effectively control the development of the three highs and the process of atherosclerosis.
