The occurrence and prevalence of many cardiovascular diseases are in a sense linked to the development of human history. In ancient times, people lived in herds of gatherers and hunters, and all they consumed was unprocessed natural food with a relatively balanced nutritional composition. With the development of production, class differentiation, environmental (including diet) changes, the phenomenon of nutritional imbalance gradually occurred. A few people may be over-nourished, while many more are in a state of nutritional deficiency. Both extremes, along with other factors, can lead to the development of a variety of different cardiovascular diseases. According to historical information, the nobility of ancient Rome lived a lavish and luxurious life with a dietary composition very close to that of present-day Western countries, and angina and sudden death have been documented to have occurred among these people. Significant atherosclerosis was also found in the dried bodies of Egyptian nobles. The female corpse of the Western Han Dynasty palace room, excavated more than 2,000 years ago in Mawangdui, Changsha, China, has been confirmed by modern pathology to have pathological changes of atherosclerosis and myocardial infarction. Nevertheless, this disease was still a minority in ancient times. In modern times, especially in Western countries, people’s lifestyles and dietary structures have changed more and more. According to late information, the average daily fat intake per person in the United States is more than 100g, and it is mainly animal fat, food cholesterol is 400-700mg, with an average of 560mg, and the intake of coarse grains is very little, while the consumption of refined sugar is high (more than 100g). In addition, the consumption of alcohol and salt is also high. The excessive intake of total calories and the imbalance between various nutrients may be one of the main reasons for the widespread prevalence of cardiovascular diseases, especially coronary heart disease. bajusz, pointing out the changes in the Western diet and the harm it brings, quoted the saying “people are digging their own graves with their own teeth.” This situation has attracted the attention of cardiologists, nutritionists, the public and the relevant sectors of society. At present, there are sixteen expert committees on “dietary fat and coronary heart disease” in the world have proposed a series of dietary reform measures. In 1977, the U.S. Congress put forward the “dietary goal” (dietary goal), advocating people to eat more grains, so that the complex sugar intake can be increased from 28% to 48% of total calories, and the fat intake can be reduced from 40% to 30% of total calories, and the ratio of animal fat to vegetable fat can be properly controlled. The ratio of animal fats to vegetable fats, increase the intake of vegetables and fruits, and limit the intake of cholesterol, sucrose and salt. The contents of the current world diet reform were actually fully reflected in the first medical classic “Huangdi Nei Jing Su Wen” in China more than 2,000 years ago. It pointed out that a reasonable diet for people should be “five grains for nourishment, five animals for benefit, five fruits for help, and five vegetables for enrichment.” This viewpoint only correctly clarifies the various nutrients necessary for human diets, and dialectically points out the primary and secondary relationships among them (i.e. nourishing, benefiting, helping and enriching). It establishes the excellent dietary characteristics of our nation and has far-reaching guiding significance for safeguarding people’s health and preventing diseases, especially coronary heart disease. This correct viewpoint has been constantly supplemented and developed in many monographs on food therapy in successive generations. For example, Gong Tingxian in the Ming Dynasty in the book “Shou Shi Bao Yuan” on the importance of dietary control has a rather incisive discussion: “good health nourisher nourish the inner, not good health nourisher nourish the outer, nourish the inner in order to calm the viscera, regulate the blood vessels, it is generally popular and a hundred diseases, nourish the outer want to wanton mouth and stomach, the extreme taste of beauty, poor diet of pleasure, although the body is full of fat, look pleasant, but the cheese strong gas, internal erosion of the viscera The spirit of deficiency is carried forward, and can keep the order too and to reach the old age …… people can be fearful, between the food and drink, and do not know as a precaution, too. “This discourse, the prevention and control of obesity, high blood pressure, hypertension and coronary heart disease, the health of the middle and elderly and prolong life is still very important. The understanding and contribution of our ancient medicine to nutrition and health and disease (including cardiovascular disease) comes from the rich practice of the people, and also guides the practice of the people. Because of this, it has a broad and profound mass base incomparable to any other nation in the world. For thousands of years, the working people of China have been using various kinds of food to maintain health and prevent diseases, many of which have become customs and habits because they have been handed down from generation to generation. However, in other countries, the situation is quite different. For example, Dock in the book “nutrition and cardiovascular disease” wrote: “more than 2,000 years ago, the ancient Greek famous doctor Hippocrates era, although the physician advised people to prevent and control disease by changing their diet, but the vast majority of patients prefer to take medicine or suffer pain, rather than take dietary measures.” Our ancient working people have long known that a vegetarian diet can prolong their lives. Modern science has proved that many ingredients in vegetarian food, such as vegetarian oil containing a large amount of polyunsaturated fatty acids and vitamin E, and shiitake mushrooms and fungus can both lower lipids and improve blood coagulation, and they are all good for preventing hyperlipidemia and coronary heart disease. Looking at the history and current situation, it is easy to see that there is a very close link between nutrition and cardiovascular diseases.
