In the Yellow Emperor’s Classic of Internal Medicine, there is a very famous phrase called “the upper worker treats the untreated disease”, and further explained from both positive and negative aspects: “The sage does not treat the untreated disease, does not treat the untreated chaos, and treats the untreated chaos, this is also called. If the disease has become and then the medicine, chaos has become and then the cure, like thirst and wear well, bucket and cast cone, is not also late! What is the meaning of this sentence? It means that a good doctor does not mean that he can “cure the disease”, but that he can “keep people from getting sick”. If people don’t get sick, they can naturally stay away from tumors. How should we do this? In October 2007, the World Cancer Research Fund released the second expert report on “Food, Nutrition, Physical Activity and Cancer Prevention” in Beijing, introducing the most comprehensive and latest international research results in the field of food, nutrition, physical activity and cancer prevention, and proposing 10 most authoritative recommendations for cancer prevention, including staying slim, exercising at least 30 minutes a day, eating less red meat, avoiding These include staying slim, exercising at least 30 minutes a day, eating less red meat, avoiding sugary drinks, eating more relatively unprocessed fruits, vegetables and beans, limiting alcohol consumption, avoiding preserved foods, breastfeeding, refusing tobacco, and not using dietary supplements. In fact, these are not enough, our ancestors have long proposed a more scientific and reasonable way of life, that is, the “Yellow Emperor’s Classic of Internal Medicine” proposed “law in the yin and Yang, and in the arts and figures, eat and drink in moderation, get up and live in a regular manner, not delusional labor, so that the form and the gods, and the end of its natural life, to the extent of a hundred years to go.” Around this core, people must take care of themselves in terms of living, eating, exercising and spirituality to maintain harmony and unity with nature in order to maintain health and end their natural life. For example, we must live in accordance with the laws of heaven and earth, in line with the changes of nature’s yin and yang. Man himself is a product of nature, the “Yellow Emperor’s Classic of Internal Medicine” said “heaven and earth together with the gas, ordained that man.” People live between heaven and earth, in the universe, all life activities are closely related to nature. Therefore, people and nature have a relationship with each other, whether the four seasons of the climate, day and night changes, or the sun and moon, geographic environment, will have an impact on the human body. In the process of long-term labor practice and struggle with disease, the ancients realized that only by following the example of heaven and earth and adapting to nature can they live in harmony with it, and people’s life, life and production can be guaranteed and sustained. In terms of diet, the dietary thinking of the ancients consisted of two main aspects: one is “eating in moderation” and the other is “being careful to harmonize the five tastes”. The Yellow Emperor’s Classic of Internal Medicine mentions: “thus full of food, tendons and veins across the solution, intestines open for hemorrhoids”, “the change of sorghum, is the birth of a large Ding”, pointing out that the diet is not an important cause of disease, while emphasizing that “five grains for nourishment, five fruits for help, five animals for the. Five fruits to help, five animals to benefit, five dishes to fill, the smell together and served, in order to replenish the essence and benefit the qi”, only in this way, the human body can take a reasonable intake of nutrients, so as to ensure the health of the organism. Life is movement, “movement is not decay”, “flowing water does not rot, the pivot is not moth-eaten”, is also our traditional Chinese health concept of exercise, but exercise should also be in the section, lived 101 years of age of the King of Medicine Sun Simiao in his “Thousand Gold Essentials” pointed out that. “The way to nourish sex, often want to small labor, but not big fatigue and strong can not be ears,” indicating that exercise for health should pay attention to the size of the amount of exercise. The amount of exercise is too small will not achieve the purpose of exercise, not fitness; too large is more than the limits of the body’s tolerance, but will make the body damaged by overwork. Emotions are the response of people to various stimuli, belonging to the normal psychophysiological phenomenon. If the appropriate and reasonable use of emotions, it is beneficial to health; on the contrary, if the mood fluctuations are too persistent, too violent, beyond the normal degree, it can make people rebellious qi, qi and blood loss, dysfunction of the internal organs and cause disease. To sum up, according to the theory of Chinese medicine, adjusting life and living, adjusting diet, regulating emotions and forming a healthy and reasonable life habit, it is possible to turn away diseases and even tumors. To sum up, there are only two aspects, on the one hand, “avoiding the evil and the wind”, that is, adjusting the life to avoid the evil and avoid “disease”; on the other hand, “being calm and void, keeping the spirit inside On the other hand, it is “calmness and emptiness, internal spirit”, which means that we should adjust our life to avoid “disease”.
