First, losing weight is the key. The proportion of obese people suffering from heart disease is much higher than that of normal weight people, especially those with "apple-shaped" figure (that is, waist and hip obesity) are more dangerous. As long as the old man loses three or five pounds, his heart condition will be greatly improved. At the same time, experts warn the fatter elderly not to expect to become supermodels at once, but to gradually achieve the goal of losing weight through a balanced diet and exercise. The second is to pay attention to diet, especially to eat less egg yolk. Insist on eating low-fat foods in daily life, such as lean meat and low-fat dairy products; And an ordinary egg yolk contains about 200 mg of cholesterol. If the elderly have high cholesterol, they can only eat two egg yolks at most a week. The third is to control emotions and exercise more. Moderate exercise for 20 minutes every day can reduce the risk of heart disease by 30%, and brisk walking has the best effect. Bad temper, unable to control yourself in case of unexpected events, is also easy to induce heart disease. Fourth, while quitting smoking, drink alcohol in moderation. The proportion of smokers suffering from heart disease is twice that of non-smokers. Studies have found that after 2-3 years of quitting smoking, the risk of heart disease will drop to the same level as that of non-smokers. Drinking 3-9 glasses of wine a week is good for the heart, but be careful not to drink too much, because drinking too much will cause heart disease. Fifth, beware of diabetes. The proportion of diabetic patients suffering from heart disease is four times that of others. Therefore, the elderly should have regular physical examinations to detect and treat diabetes at an early stage.
