To put it simply, coronary heart disease is a disease with narrow blood pressure in the heart artery, and to be precise, it is coronary atherosclerotic heart disease, because the heart artery is called coronary artery. When arteriosclerosis, that is, what people call vascular garbage aggravates, causes plaque, and when the plaque narrows more than 50%, it is called coronary heart disease.
A large number of data tell us that high sodium salt will lead to a significant increase in the risk of hypertension. Eating 3 grams of salt a day may increase blood pressure by 4-5 mm Hg. At present, the salt intake of most people in China is over 6g. Hypertension itself is the main cause of atherosclerosis. At the same time, high sodium salt itself will increase the risk of atherosclerosis, so our high salt food will harm the heart.
The vast majority of patients with coronary heart disease are not due to coronary atherosclerosis, and the vast majority of patients with coronary heart disease are not due to coronary atherosclerosis. At present, medical research believes that high cholesterol, especially low-density lipoprotein cholesterol, is the chief culprit of atherosclerosis.
Although I have mentioned it in many popular science articles and videos, the increase of cholesterol is only about 20%, and about 80% is caused by metabolism. But isn't this 20% important for patients who already have coronary heart disease or hypercholesterolemia?
High-fat food is easy to understand, in layman's terms, it is greasy, and the most common is fat. In fact, greasy food includes all kinds of fried food, cakes, cream and so on. Trans fatty acids contained in these foods are also harmful to blood vessels.
Foods with high cholesterol mainly include animal viscera, such as liver, gastrointestinal tract, kidney, lung, etc. Animal brain tissue has the highest cholesterol content, and it is the pig brain that many people like to eat; Egg yolk cholesterol content of poultry eggs, eggs, duck eggs and goose eggs is high; In addition, crab roe and fish roe are also rich in cholesterol.
Excessive drinking is one of the important factors of hypertension in China. According to the dietary guidelines of China residents, men should not drink more than 25g (alcohol) every day, which is equivalent to 50ml of white wine, 0/00ml of red wine/kloc and 300ml of beer. Women are not higher than 15g (alcohol). Long-term drinking, especially heavy drinking, will lead to an increase in blood pressure, and heavy drinking will easily lead to blood pressure fluctuations.
For many people in China, it should be said that we usually eat more rice and white flour, but less fresh fruits and vegetables. This eating habit has caused a lot more patients with diabetes and hyperlipidemia in China, and because of eating less vegetables and fruits, many people lack folic acid, which leads to the increase of homocysteine, and finally the increase of patients with cerebral infarction. Therefore, Dr. Zhang should advise everyone to eat more fresh fruits and vegetables and pay attention to the intake of rice and white flour.
Refined grains, such as fortified flour and instant rice, are grains lacking valuable nutrients, such as fortified flour and instant rice. It is suggested to use 100% whole grains instead of flour and rice products, which is an effective method to prevent heart disease. For example, brown rice or wild rice is used instead of white rice, and oatmeal or whole grain bran chips are used instead of sugary low-fiber grains.
Foods rich in fiber can also improve appetite control and ease the process of weight control-another important factor to avoid heart disease. Other refined grain products worthy of restriction include concentrated pasta, pretzels, white bagels, cakes and tortillas.
Heart health is related to overall health. The occurrence of heart problems is related to many factors, including disease factors and dietary factors. If you want to protect your heart health, you must pay special attention.
In addition to paying attention to diet and protecting heart health, we need to start from all aspects of life. Tobacco and cigarettes contain a variety of carcinogens, which can cause respiratory tumors such as lung cancer. Cigarettes can contract blood vessels and cause vascular endothelial cell damage. Alcohol is also a primary carcinogen, which can cause alcoholic myocarditis and damage blood vessels.
Besides paying attention to diet and protecting heart health, we need to start from all aspects of life. For example, patients should pay attention to the monitoring of blood pressure, blood lipids and other indicators, especially middle-aged and elderly patients, and must pay attention to regular physical examination.
In addition, in life, we should pay attention to moderate exercise every day, avoid sedentary, mainly aerobic exercise, exercise for 30 minutes every day; Quit smoking and drinking; Don't stay up late for a long time, be nervous, overworked and stressed. , and pay attention to maintain a regular schedule to ensure adequate sleep; Avoid bad emotions such as anxiety and anger, and maintain a good attitude.
