A healthy lifestyle can reduce the risk of cardiovascular disease by eliminating behaviors and habits that are detrimental to mental and physical health, and preventing the disease before it occurs. The WHO recommends a daily salt intake of no more than 6 g per person, a reduction in the amount of salt used in cooking and in seasonings with high salt content, and a reduction in the amount of salted vegetables and salt-pickled foods. (2) reduce dietary fat, supplemented with an appropriate amount of high-quality protein. A study showed that eating fish four times a week or more compared with eating fish at least, the incidence of coronary heart disease reduced by 28%. Reduce the fatty pork, increase the protein content of higher and less fatty poultry and fish. Protein quality in order: milk, eggs, fish, shrimp, chicken, duck, pork, beef, lamb; vegetable protein to beans is the best. (3) Supplement potassium and calcium. The Chinese diet is low in potassium and calcium, and foods with high potassium and calcium content should be increased, such as green leafy vegetables, fresh milk and bean products. (4) Eat more vegetables and fruits. Studies have proven that increasing vegetable or fruit intake and reducing fat intake can lead to a decrease in blood pressure. The human diet should be mainly vegetarian, the appropriate amount of meat is ideal. (5) Limit alcohol consumption. Although studies have shown that very small amounts of alcohol may reduce the risk of coronary heart disease, there is a linear correlation between alcohol consumption and blood pressure levels and the prevalence of hypertension, and heavy alcohol consumption can trigger cardiovascular events. Therefore, small amounts of alcohol are not advocated for the prevention of coronary heart disease, and patients with hypertension should abstain from alcohol because it can increase resistance to antihypertensive medications. If drinking alcohol, it is recommended that the daily amount of alcohol should be a small amount, with men drinking no more than 30 grams of alcohol, that is, less than 100-150 ml (2-3 taels) of wine, or less than 250-500 ml (half a pound-1 pound) of beer, or less than 25-50 ml (0.5-1 taels) of white wine; women are reduced by half the amount, and pregnant women do not drink alcohol. The WHO’s new recommendation for alcohol is that the less you drink, the better. Quit smoking: Quitting smoking is also very important. The success of quitting smoking depends mainly on the perseverance and determination of the smoker. Increase physical activity and reduce weight: Know your physical condition before exercising to decide on your type, intensity, frequency and duration of exercise. For middle-aged and elderly people, aerobic, stretching and muscle-strengthening exercises should be included, and specific items can be chosen from walking, jogging, taijiquan, gateball, qigong, etc. Exercise intensity varies from person to person, commonly used exercise intensity indicators can be used when the maximum heart rate of 180 (or 170) minus age, such as 50-year-old people exercise heart rate of 120-130 times / min. Exercise frequency generally requires 3-5 times per week, lasting 20-60 minutes each time, depending on the physical condition of the exerciser and the type of exercise chosen, as well as climatic conditions. Body mass index (BMI) is obtained by dividing the number of kilograms of body weight by the square of height (kg/m2), and it is recommended that BMI should be kept below 24. The health benefits of weight loss are enormous; for example, a 5-10 kg average weight loss in a population can lead to a 5-20 mmHg decrease in systolic blood pressure. a 10% weight loss in hypertensive patients can lead to improvements in insulin resistance, diabetes, hyperlipidemia and left ventricular hypertrophy. Weight loss is achieved by reducing total caloric intake, emphasizing less fat and limiting excessive carbohydrate intake, on the one hand, and increasing physical activity on the other. Reducing mental stress and maintaining mental balance: Chronic mental stress and depression is one of the major causes of hypertension and some other chronic diseases, and this mental state often makes them less likely to adopt healthy lifestyles, such as alcohol and tobacco use, and reduces compliance with anti-hypertensive treatment. People with mental stress and psychological imbalance should reduce mental stress and change their mindset, treat themselves, others and society correctly, and actively participate in social and group activities.
