1. Avoid greasy food. For patients with coronary heart disease, the daily diet must be light.

Usually, you should eat more fresh vegetables, fruits, black fungus, or soy products. You can also eat some lean meat and fish appropriately, and try to eat less greasy or high-fat food. If you have the conditions in your daily life, you can drink more mung bean soup, lotus seed soup, lily soup or chrysanthemum tea, lotus leaf tea and other drinks.

2. The incidence of coronary heart disease in smokers who avoid alcohol and tobacco is three times higher than that in non-smokers

Drinking hard liquor often can lead to heart disease and hyperlipidemia due to alcoholism. Excessive ethanol can also increase the oxygen consumption of the heart and aggravate coronary heart disease. Smoking should be stopped and alcohol should be restricted, and irritating foods such as strong tea and peppers should also be carefully eaten.

3. Avoid overeating. Patients with severe coronary heart disease should adopt the principle of eating a little more meals.

Avoid overeating, especially at dinner. Try to eat as much digestible food as possible, and at the same time keep your stool unobstructed.

4, avoid cold drinks

We must pay attention to fasting cold drinks every day, because when the temperature is high, the blood vessels are in a state of dilation. Once we eat cold drinks, the intestines of most patients will be stimulated suddenly, and then the whole body blood vessels will contract, and blood pressure will suddenly rise, which is easy to cause angina pectoris, myocardial infarction and cerebral hemorrhage.

5. Avoid eating sugar

Sugar refers to carbohydrates, which are the main source of body heat energy. Excessive intake can cause excess heat, which can be converted into fat in the body, causing obesity and raising blood lipids. Therefore, it is necessary to strictly control the total intake of carbohydrates, especially the intake of sugar. Studies have proved that fructose is higher than sucrose and sucrose is higher than starch in raising blood lipid in carbohydrates. Therefore, it is recommended to eat complex carbohydrate and control refined sugar: choose foods rich in plant fiber such as starch, brown rice and corn, and eat less monosaccharides such as sucrose and fructose.

6. Avoid dehydration

Some middle-aged and elderly people don't have the habit of drinking water regularly, but wait until they are thirsty and want to drink. In fact, this has caused dehydration to varying degrees. Old people should develop the good habit of drinking water regularly. The blood viscosity of the elderly (especially patients with coronary heart disease) has increased. Dehydration leads to an increase in blood concentration. To a certain extent, there will be a tendency of blood coagulation, which will lead to ischemia or cardiovascular and cerebrovascular blockage, and even lead to myocardial infarction or stroke in severe cases. It is recommended to drink some boiled water half an hour before going to bed, or after waking up in the middle of the night and getting up in the morning.
