"People eat for heaven." Rites of Passage" says: "Diet and men and women, the great desire of man exists." Diet as the nature of life, as the first need of life, to solve the problem of eating is of course the most important thing in life.
In the past, there was a slogan called "life is movement", while nutritionists have proposed "life is nutrition".
Life as the essence of man, as the embodiment of man alive, it depends on the premise of existence is nutrition. Exercise requires nutrition to provide energy, that is, static also still need nutrition to maintain, but the consumption of some of the lower just. Life requires nutritional support, and diet is a source of nutrients for the body.
Our ancestors recognized the importance of the relationship between diet and life nutrition very early, recorded in the "Huangdi Neijing" of the relevant discussion is very much. For example: "Food gas into the stomach, scattered in the liver, obscene gas in the tendons; food gas into the stomach, turbid gas to the heart, obscene essence in the veins." (Su Wen - Jing Wei Bie Lun) "The five flavors enter the stomach, each returning to its own liking; therefore, sour first enters the liver, bitter first enters the heart, sweet first enters the spleen, pungent first enters the lungs, and salty first enters the kidneys, and for a long time, it increases the qi, and it is a common practice for the materialization of things." (Su Wen - Zhi Zhen Yao Da Lun) "Taste goes to form, form goes to qi, qi goes to essence, and essence goes to chemistry." "If the form is insufficient, warm it with qi; if the essence is insufficient, replenish it with flavor." ("Su Wen - yin and yang should be like a great theory")
In short, Chinese medicine believes that the diet into the human body, through the digestion and absorption of the stomach, the spleen's transportation, and then transported all over the body to nourish the internal organs, qi and blood, meridians, limbs, muscles, and even bones, skin and hair, nine orifices, and then fill the essence of the essence of the essence of the essence, in order to feed the spirit to play a role in the prevention of disease, to slow down the aging process and to prolong the life of the role of the body.
The body's essential nutrients, including water, carbohydrates, fats, proteins, vitamins, minerals, six categories of nutrients, these six categories of nutrients mainly from daily food, is to rely on "eat" to provide.
From the point of view of health, six types of nutrition should be complete, the supply must be sufficient, the structure should be reasonable.
Nutrition is not the more the better, nutrient intake and age and physical exertion to adapt, such as young people are growing, or physical exertion, intake should be more to strengthen the nutrition. Of course, if you disregard the specific circumstances, desperately "strengthen nutrition" will appear "overnutrition", so that too much "fat", "hair fat "
Nowadays, there is a lot of people who are not interested in the same thing.
Now the problem is that many people do not worry about nutritional deficiencies, but rather afraid of the intake of certain nutrients, especially on fat, cholesterol, sugar foods fear like a tiger. In fact, fat, sugar are the main substance of the body's heat, is the power of life, if the intake is not enough to affect the body's physical ability. Cholesterol is a mixed blessing, it does cause hypertension, atherosclerosis, coronary heart disease and other diseases, but it also promotes brain information transfer, improve brain function, active thinking, enhance memory and other extremely important role. The body has a feedback mechanism for synthesizing cholesterol, and cholesterol in the body can be maintained at a dynamically balanced level. Therefore, eating the right amount of cholesterol is not harmful to the human body.
The theory of Chinese medicine's five flavors and its reasoning is also to emphasize the comprehensive balance of nutrition. Food has sour, bitter, sweet, pungent, salty five flavors, which is well known. Chinese medicine believes that the five flavors are properly harmonized, can be beneficial to health, while the five flavors are biased, will cause disease.
Diet should be regular and quantitative. Sun Simiao in the "Preparing for the emergency Qianjin to formula - Nurture" also emphasized that the diet must be timed, he said: "Do not want to eat extremely hungry, food can not be too full; do not want to drink extremely thirsty, drink do not want too much. Too much satiety will accumulate, too much thirst and drink will become phlegm." Eat three meals a day, morning, noon and night, and have a fixed time for eating. Each time you eat should be quantitative, not big ups and downs.
Eating to maintain a good mood. Eating must be excluded from all worries and troubles, make sure that the mood is relaxed and happy, do not be angry and frightened, otherwise appetite is sharply reduced, even if the food is difficult to digest, and even affect the night's sleep. "Thoughts hurt the spleen", long-term bad mood, will damage the spleen and stomach, which in turn cause other diseases. On the contrary, if the spirit is happy, the appetite will also increase, and the stomach and intestines will be able to digest food and absorb nutrients well. In this way, the weak can strengthen the body, but also can make the hold disease infected people quickly healed.
Hot and cold diet should be moderate.
Hot and cold drinks in the summer and hot food in the winter, this is human nature. But the diet of hot and cold, must be moderate, not too biased. Even if it is a hot summer, can not be too addicted to cold drinks cold food, or easy to damage the spleen and stomach. Similarly, hot food should also have a certain limit. Sun Simiao in the "Thousand Gold Wings - Nutritional Taboos" said: "Hot food hurt bones, cold food hurt lungs, hot without burning lips, cold without ice teeth." It is very important to master the degree of hot and cold food, too cold food will cause diarrhea, and even more than a discharge; and too hot food, the esophagus and stomach will be equally damaged.
Eating should be chewed and swallowed slowly. Chinese medicine advocates "drink must be fine sip", because "big drink is gas reverse", resulting in choking or asthma, and even cause phlegm drink disease. Eating must be chewed slowly, avoid swallowing.
Insist on gargling and walking after meals.
The change of climate in nature has a great impact on the human body. Since ancient times, China's traditional method of health care that is, "the four seasons of regulation" said. The diet of the four seasons is also an important aspect of the regulation.
In terms of dietary taboos, Sun Simiao pointed out that there are dietary taboos due to disease, such as "Preparing for the emergency Qianjin key formula - typhoid fever - labor recovery" in the cloud: "when the disease is poor, not yet full of five days, eat all the meat face, the disease is more hair big sleepy; when the disease is poor after the new start, drink alcohol and leeks, the disease is more; when the disease is poor, eat raw fish vinegar, under the Lee must be more than; when the disease is poor, eat raw vegetables, so that the color of a lifetime! Not flat back; when the disease of new sweat solution, drink cold water damage to the pericardium, people are not back to the virtual; when the disease of the new difference, eating raw dates and mutton, must be diaphragm for hot steam; when the disease of the new difference, eating dogs and sheep and other meat, for the bone in the steaming heat; when the disease of the new difference, eating fish and melons, lettuce, people's body heat; when the disease of the new difference, eating garlic chopped, the disease will lead to a big sleep". Description of typhoid fever when the disease is first recovered, the diet should pay attention to appropriate taboos.
