What precautions should the elderly take to prevent coronary heart disease by eating vegetarian food?

　　People who are moderately vegetarian have lower blood viscosity, and the blood can flow unobstructed in the blood vessels, and will not cause myocardial ischemia and hypoxia due to blood vessel obstruction, causing coronary heart disease . But long-term vegetarianism is not conducive to healthy , and is also one of the factors leading to coronary heart disease. This is because, except for legumes, which are rich in protein, other foods in vegetarian diets contain less protein and have lower nutritional value, making them difficult to digest, absorb and utilize by the human body. Long-term vegetarianism can cause insufficient intake of protein, fat, fat-soluble vitamins A, D, E, K and trace elements in the human body, leading to nutritional imbalance and significantly reducing the body's resistance, thus making people susceptible to infectious diseases, osteoporosis, fractures, etc. The most important thing is that people who have been vegetarians for a long time will also lack vitamin B12 in their bodies, which will cause the inner walls of arteries to thicken and lead to arteriosclerosis, which is the basis for coronary heart disease.

　　Therefore, an appropriate vegetarian diet can prevent coronary heart disease, but long-term vegetarianism may become a risk factor for coronary heart disease. It can be seen that to prevent coronary heart disease, one should have a reasonable diet and balanced nutrition. elderly The daily diet should be light and nutritious, and avoid long-term vegetarianism, overeating, sweets, salty foods and other bad habits; eat less or avoid foods with high cholesterol and saturated fatty acids; eat more whole grains, vegetables, fruits and some protective foods, such as soy products, yams, fungus, mushrooms, kelp, seaweed, fish, skimmed milk powder, yogurt, celery, eggplant, leeks, lean pork, etc.
