In the process of clinical diagnosis and treatment, there are always many patients with cardiovascular disease will have doubts: “Doctor, I usually eat what to pay attention to?” Doctors will generally emphasize with the patient should be “light diet”, then light diet on cardiovascular disease prognosis of what benefits? Recently, European researchers conducted a large-scale follow-up survey, the results of which were published in the European Heart Journal. The survey looked at the health of more than 300,000 people in eight European countries, who were followed for an average of eight and a half years. The study found that people who ate more fruits and vegetables had a significantly lower risk of dying from coronary heart disease than those who ate fewer fruits and vegetables. Those who ate more than 640 grams of fruits and vegetables per day had a 22 percent lower risk of dying from coronary heart disease than those who consumed less than 240 grams of fruits and vegetables per day. Meanwhile, Meta-analysis of a prospective cohort study completed by a team of researchers from China in collaboration with Harvard Professor Frank B Hu et al. also found that, compared with those who did not consume fruits or vegetables, the mortality rate of patients with coronary heart disease who consumed 80 grams of fruit or vegetables per day could be reduced by 8%, and then every time they increased the intake of 80 grams of fruits and vegetables, the risk of death of patients with coronary heart disease could be reduced by about 4%, and the amount of fruits and vegetables consumed daily When the daily intake of fruits and vegetables reaches 400 grams, the maximum effect can be achieved, and on this basis continue to increase the intake of fruits and vegetables, coronary heart disease mortality risk rate is no longer reduced. Therefore, for patients with coronary heart disease, we recommend a daily intake of about 400-600 grams of fruits and vegetables. For patients with coronary heart disease, it is recommended to consume more fruits and vegetables that are high in fiber. Dietary fiber is a large group of sugars that are part of plants and are not digested by the body, and have significant health benefits. There are more than a thousand types of dietary fiber in nature. Dietary fiber from different sources, because of its chemical composition varies greatly, so the physiological effects of the differences are also very large. The common characteristics of dietary fiber are that it cannot be broken down and utilized by small intestinal enzymes, it has a low energy value, and it can produce short-chain fatty acids by fermentation under the action of intestinal bacteria, which promotes a wide range of health effects such as probiotics. Dietary fiber has certain health benefits in terms of intestinal health, blood sugar regulation and type 2 diabetes prevention, satiety and weight regulation, prevention of lipid metabolism disorders, and prevention of certain cancers. Vegetables with high fiber content include bamboo shoots, ferns, cauliflower, spinach, pumpkin, cabbage, rape, shiitake mushrooms, silverbeet, fungus, purple cabbage, etc. Fruits with high fiber content include dried red fruits, sour horn, dried mulberries, cherries, sour jujubes, black jujubes, jujubes, jujubes, pomegranates, apples and duck pears. Note: Patients with coronary heart disease combined with diabetes need to pay attention to the amount of fruit intake.
