Yi hexagrams, the "root" of the upper hexagrams is the mountain, and the "truth" of the lower hexagrams is the thunder. A gentleman should pay attention to his words and diet.
It is not difficult to see that the ancients put forward the view that diet should be moderate.
Later generations inherited and developed the principle of keeping in good health in Zhouyi. "Guanzi" said: "Dieting is good for health and prolongs life; If you don't eat well, you will be tired and you will lose your life. "
Now I can also learn a lot from the ancient people's health care methods. Let me summarize the following points for you:
opportunity
Regular diet is an important condition to keep healthy. "Lu's Spring and Autumn Annals" says: "If you can eat in time, you will be safe." Shangshu also advocates that "food is out of date". Eating regularly in a certain period of time can make the human body establish conditioned reflex and ensure the rhythmic movement of digestion and absorption function.
During the day, the yin, yang, qi and blood of the human body change day and night, rising and falling differently. During the day, the yang is strong, so the metabolism is strong, and the required nutrient supply is bound to be more, so the diet can be slightly larger; At night, the yang is weak and the yin is abundant, and most of them rest and go to bed, which requires less nutrition supply. Therefore, the food intake can be slightly less, which is also good for the digestive function of the gastrointestinal tract. Therefore, the ancients had the motto "Good breakfast, full lunch and little dinner".
The traditional way of eating in China is three meals a day. If you can eat regularly and develop good eating habits, your digestive function will be healthy, which is of great benefit to your health.
quantify
Quantification means eating moderately and being full. The human body needs to eat a certain amount of food every day to maintain the needs of life activities. If the intake is insufficient, the human body will not get enough nutrition, which will affect health and even breed various diseases. On the other hand, if the amount of food exceeds a certain limit, it will also damage the function of the spleen and stomach and cause diseases.
In addition, we can eat as needed.
The so-called "eat as needed" means to eat more if you want, and eat less if you don't want to eat. People who work at night often don't want to eat breakfast the next day, hoping to have a good sleep as soon as possible; People in a bad mood often have no appetite when eating.
Tao Hongjing pointed out long ago: "If you are not thirsty, you will have abdominal distension, and if you are not hungry, you will have spleen deficiency." "Eating on demand" is adopted to adapt to changes in physiology, psychology and environment.
A new way of eating, which is not absolutely inseparable from snacks, is to adapt to the external environment and internal needs, making eating activities more in line with the law. Eating on demand and eating on time complement each other and can meet people's dietary needs in different environments.
In a word, the dietary principles in Zhouyi have a far-reaching impact on health preservation, which provides a theoretical reference for modern dietary health preservation methods.
