(A) improper diet
Diet is expensive in moderation. Eating regularly and quantitatively is called moderate eating.
1. Hunger and satiety disorders: Eat moderately, and diseases may occur when you are full. Obviously lower than my moderate diet, that is called starvation; Obviously exceeding my moderate diet is called satiety. When you are hungry, you will eat less and lack chemical sources, which will eventually lead to less qi and blood. Deficiency of qi and blood will lead to emaciation, weakness of vital qi and decreased resistance, which will easily lead to other diseases. On the other hand, overeating that exceeds the digestion and absorption function of the spleen and stomach will lead to diseases that damage the spleen and stomach, such as indigestion, bloating, rancidity and pantothenic acid, anorexia, vomiting and diarrhea. Therefore, there is a saying that "the diet is doubled and the stomach hurts".
Hunger and satiety disorders are particularly common in children, because their spleen and stomach are weaker than those of adults, and depression can turn into heat after long-term eating; Treatise exogenous febrile diseases on cold can accumulate dampness and produce phlegm. Infants and young children who eat for a long time can also have symptoms such as fever of hands and feet, upset and easy to cry, abdominal distension, yellow complexion and hunger, which is called "malnutrition". If adults overeat for a long time, it will often block the blood circulation of gastrointestinal meridians, leading to diarrhea, bloody stool and hemorrhoids. Overeating is fat and sweet, and it is easy to get angry and even cause carbuncle and sore.
In short, it is not appropriate to eat in the case of extreme hunger, and the food should not be too full; Extreme thirst is not suitable for drinking, and it is not suitable for excessive drinking. Eating too much will accumulate; Too much thirst leads to wet phlegm.
In addition, in the course of the disease, improper diet will also change the condition, so there is a saying of "food recovery". For example, in the case of fever, when the disease begins to heal, the spleen and stomach are still deficient, and overeating or eating too much food often leads to excessive food accumulation, which is combined with residual heat to make the heat evil stay for a long time, leading to the recurrence or delay of the disease.
Eating all the time: Eating regularly at a fixed time can ensure that the digestion and absorption function can be carried out rhythmically, and at the same time, the spleen and stomach can be coordinated and relaxed. Shui Gu is subtly and orderly distributed all over the body. Since ancient times, three meals a day, "breakfast is better, lunch is full, and dinner is less." If the diet remains unchanged, it will also damage the spleen and stomach and cause other diseases.
(2) Dietary preference
Reasonable diet structure, harmonious five flavors, moderate cold and heat, and no partial eclipse can make the human body get all kinds of nutrients it needs. If the diet is partial or the diet structure is improper, or the diet is too cold and too hot, or the diet is partial, it can lead to imbalance between yin and yang, or some nutritional deficiencies and diseases.
1. Species preference: Only a reasonable diet and a reasonable diet structure can get enough nutrition to meet the needs of life activities. People's dietary structure should be complete with cereals, meat, fruits and vegetables, mainly cereals, supplemented by meat, vegetables and fruits. Reasonable collocation according to needs is beneficial to health. If the structure is uncomfortable, the preparation is not suitable, the taste is biased, and the dirty is biased, resulting in visceral dysfunction. If the crystal is too addicted to yeast, it will lead to the accumulation of water and drinks; If you are too addicted to eating melon and fruit crisp, the water will be wet and endogenous, and it will be swollen and diarrhea.
2. Cold and heat preference: the diet should be moderate in cold and temperature, otherwise too much cold food can damage the yang of the spleen and stomach, endogenous cold and dampness, abdominal pain and diarrhea. Partial eating of pungent, warm and dry heat can cause gastrointestinal heat accumulation, thirst, abdominal distension and pain, constipation, or hemorrhoids.
3. Five flavors bias: people's spiritual qi and blood are all born of five flavors. Five flavors and five internal organs have their own affinity, such as sour liver, painstaking, sweet spleen, pungent lung and salty kidney. If you like a certain food for a long time, it will make the function of viscera rise and fall. Over time, it can spread according to the relationship between the five internal organs, damage his organs and cause diseases. If you eat more salty things, your blood will stagnate and your face will lose its luster; Eating more bitter things will make the skin dry and the hair fall off; Eating more spicy food will make tendons tense and claws wither; Eating more sour food will make the skin tight and shrink, and the lips will be dry and thin. If you eat too much sweet food, your bones will hurt and your hair will fall out. In addition, excessive hobbies will lead to malnutrition and lack of some necessary nutrients, which will affect the viscera as a disease. Such as beriberi, night blindness, swelling and pain. It is the result of five flavors. Therefore, the five flavors of diet should be appropriate, and the diet should not be partial. Pay attention to your diet and avoid eating when you are sick. Diet should be suitable for illness, which can be used as adjuvant therapy to promote the improvement of illness. On the contrary, it will aggravate the condition. Only "harmony of five flavors" can "have a definite number"
(3) unclean diet
Unclean eating can cause a variety of gastrointestinal diseases, such as abdominal pain, vomiting and diarrhea, dysentery and so on. Or cause parasitic diseases, such as roundworms, pinworms, white worms, etc. And the clinical manifestations are abdominal pain, eating foreign bodies, sallow and emaciated. If ascaris enters the biliary tract; Severe pain in the upper abdomen, intermittent vomiting and cold limbs may also occur. If you eat rotten and toxic food, it will cause food poisoning, often accompanied by abdominal pain and vomiting, and even coma or death.
