Introduction：The Yellow Emperor’s Classic of Internal Medicine, as a classic work of traditional Chinese culture, is not only a classic Chinese medical masterpiece, but also a profound and profound cultural masterpiece, which focuses on life, discusses the interconnection among heaven, earth, and human beings from a macroscopic point of view, discusses and analyzes the law of life, which is the most basic proposition of the medical science, and creates the corresponding theoretical systems and principles and techniques for the prevention and treatment of diseases, containing a wealth of knowledge from a wide range of disciplines such as philosophy, politics, astronomy, etc. It is an encyclopedia centered around the issue of life. Modern nutrition believes that only daily intake of comprehensive and reasonable dietary nutrition, i.e. balanced diet, can ensure the daily needs of the human body and maintain human health. In the world’s dietary history, it was China that first put forward the idea of “balanced diet”. Written more than 2,000 years ago, the Chinese medical text “Yellow Emperor’s Classic of Internal Medicine” has been “five grains for nutrition, five fruits for the help, five animals for the benefit of five vegetables for the full, the smell of the combined service to replenish the essence of qi” and “grain, meat, fruits, vegetables, food and nutrition to exhaustion, do not make it too much to injure its own positive” records. The content of the above balanced diet is ancient and not old, very scientific reasoning. “Five grains for nourishment” refers to wheat, millet, rice, beans and corn and other grains and legumes as a staple food to nourish the human body. As analyzed from a modern nutritional point of view, wheat, corn, rice, corn is rich in carbohydrates and proteins, beans are rich in proteins and fats. Grains and beans eaten together, nutrients can complement each other, promote absorption, thus greatly improving the nutritional value. Our people for thousands of years since the formation of the dietary habits is to carbohydrates as the main source of calories, and human growth and development of their own repair is mainly dependent on protein. Therefore, “five grains for nutrition” is also very consistent with the modern nutritional point of view. “Five fruits for help” is to eat some dates, plums, apricots, chestnuts, peaches and other fruits, nuts, help to nourish the body and fitness. Because fruit is rich in vitamins, fiber, sugar, trace elements and organic acids and other nutrients, raw food can avoid the destruction of its nutrients due to cooking. Some fruits can also help digestion if consumed after meals. Therefore, five fruits are indispensable supplementary food in a balanced diet. “Five animals for the benefit” refers to eat some cattle, dogs, sheep, pigs, chickens and other livestock meat, the human body has a complementary effect, can supplement the nutritional deficiencies of the five grains and cereals staple food, is the main complementary food of a balanced diet recipes. Animal food is mostly high in protein, fat and calories, and contains essential amino acids, which are important nutrients for the normal physiological metabolism of the human body and the enhancement of the body’s immunity. “Five vegetables for the full” means with eating some sunflower (winter sunflower, amaranth), leek (leek), scallion (Allium scallion head, wild garlic, “buckwheat”), patchouli (bean seedling, the young leaves of the bean), green onions and other vegetables can be supplemental nutrients. Because a variety of vegetables contain a variety of trace elements, vitamins, fiber and other nutrients, often eat vegetables have to increase appetite, full of hunger, digestion, nutrition, anti-constipation, lowering blood lipids, lowering blood sugar, prevention of intestinal cancer and other roles, so it is very beneficial to human health. Yellow Emperor’s Classic of Internal Medicine” put forward by the principle of dietary preparation tells us to eat to the five grains as the main food, so as to maintain life, and then eat some meat, vegetables and fruits as appropriate as an auxiliary supplement to the necessary nutrients, to achieve a balanced diet. Do not overeat or dietary preferences (only eat a flavor such as sweet or eat only one kind of food), because “do not make too much of it, hurt its integrity”! If you eat too much, you hurt your body. Remember what Dr. Tsang said earlier: you are eating and the food is eating you! For thousands of years, these principles have served as the guiding principles for the dietary structure of the Chinese nation, and have played an extremely important role in ensuring the health and prosperity of the entire nation.
