Diet is the main way for human body to absorb nutrition and energy from the external environment, and it is the basis and expression of life activities, which is closely related to human survival. Its fundamental purpose is to make people full of popularity, energetic, prosperous, healthy and long-lived. The theory of diet regimen came into being with China's cooking and developed with the development of cooking.
The change and development of China's cooking diet has always been under the guidance of philosophy and health preservation. For example, Confucianism advocates etiquette and music, and the diet is timely; Taoism advocates nature, diet and health; Yin-yang family and doctors' yin-yang, five elements, four qi and five flavors; Buddhist abstinence, vegetarianism and so on, these philosophies about diet have a profound influence on China's cooking, so China said that "medicine and food are homologous". It can be seen that diet is very important to human health. Li Shizhen, a medical scientist in the Ming Dynasty, said: "Eating and drinking is also the lifeblood of people." . In the human body, yin and yang run and the five elements coexist because of the role of diet. Modern medicine also believes that diet is the fundamental condition for maintaining human life activities and is very important for personal health. Proper diet can absorb various nutrients and prolong life. Many diseases can be prevented and alleviated by diet. Improper diet is also the cause of illness and early death. Therefore, it is not enough for many people to think about food only from the perspective of taste. The homology of medicine and food is a remarkable feature of China's health culture.
China has had the saying of "eating, nourishing, dietotherapy and taboo" since ancient times. The thought of homology of medicine and food has formed a unique tradition and system in China. It is natural that doctors eat food and chefs cook according to the functional taste of food. In modern times, there is also special nutrition research. The homology of medicine and food is actually a close combination of medical care and food support, which makes medicine and food serve the purpose of eliminating diseases, prolonging life and strengthening the body. On the other hand, China's health experts all attached great importance to "moderate diet". "If you don't want to be extremely hungry, you can't eat too much; Don't drink or drink too much if you don't want to be extremely thirsty. " "Don't eat too much at night", "One-day taboo: don't eat too much at dusk" and so on. Many health experts agree that "hunger hurts the spleen and satiety hurts the qi". People who are good at nourishing nature should be moderately hungry, eat when they are hungry, drink water when they are thirsty, and eat more in small quantities.
The human body is a balanced whole, and the storage, transformation and utilization of energy should be balanced in the process of renewal. Proper exercise is a necessary condition to maintain this balance. We should be satisfied with hunger and hungry. Eating too much increases the burden on the gastrointestinal tract, which is not conducive to digestion, especially before going to bed. Too much energy can lead to obesity and many diseases. Girls should pay special attention to this, which is a taboo to lose weight. At the same time, pay attention to the peace of the five flavors and don't overdo it. Food has five flavors: sweet, sour, bitter, spicy and salty. Acid belongs to spring, bitter belongs to summer, spicy belongs to autumn, and salty belongs to winter. Therefore, in spring, summer, autumn and winter, food is made up of four flavors: sour, bitter, pungent and salty. Proper consumption of the five flavors can nourish the five internal organs, increase appetite and be beneficial to health; But it is too wide, the related organs are overwhelmed and easy to get sick. Modern medicine believes that too strong acidity will induce or aggravate ulcer disease; Excessive intake of sugar is closely related to cardiovascular disease, diabetes, obesity, myopia and dental caries. Excessive salt is an important cause of cardiovascular diseases such as coronary heart disease, hypertension and arteriosclerosis.
Health experts in China have always advocated that the diet should be light and avoid heavy taste and fat. Obviously unclean, spoiled and infected meat can't be eaten, so needless to say. Especially now is the epidemic period of influenza virus, so we should pay more attention to food safety. It is important to eat less meat and more vegetables, fruits and other beneficial foods. Light food is generally beneficial to digestion and absorption and can prevent many diseases. Eating more meat, especially fat meat, is easy to cause cardiovascular diseases. Therefore, it is more reasonable to give priority to vegetarian food, supplemented by meat, and accept both vegetarian and vegetarian food. Diet should be in chronological order, pay attention to the season. To reconcile the taste of diet, we should not only conform to the time sequence, pay attention to the seasons, treat diseases with diet, but also conform to the laws of nature and the principle of adjusting seasons. In addition, be cheerful when eating, don't be depressed, don't be angry. A calm and happy mood is conducive to normal digestive function and is of great significance to health. Happiness and cheerfulness are the first keys to health. When eating, such as quarreling and getting angry, or being depressed inside, it will affect digestion and lead to various diseases. Similarly, music is of great benefit to digestive function. Isn't it nice for families to get together for dinner and play a melodious music?
Morning is the beginning of the day. At this time, no matter how much food you eat, these foods can be digested and absorbed during hair growth and growth. At night, the human body began to calm down. At this time, if you eat too much food, you will not only have a bad digestion and absorption, but also stop digesting these foods, which is not only useless, but also harmful to your health. So, eat enough in the morning and eat less at night. Some girls, in order to lose weight, skip breakfast in the morning and cut down on food at noon. They are dizzy and can't help but have a full meal at night. In fact, no matter how much food you eat in the morning, it can be digested and absorbed with daytime exercise and will not make people fat. You can't lose weight by sleeping when you are full at night. These are not healthy eating habits. In addition, research shows that skipping breakfast will accelerate aging. Because during sleep, the stomach is still secreting a small amount of gastric acid. If you don't eat breakfast and there is no food to neutralize stomach acid, it will stimulate the gastric mucosa and cause stomach discomfort, which may lead to gastritis and ulcer disease over time.
If you don't eat breakfast, you have to use glycogen and protein stored in your body. Over time, it will lead to dry skin, wrinkles and anemia, and accelerate the aging of your body. But for students, teachers, doctors and other mental workers, because of the need for mental work at night, not only can we not eat less dinner, on the contrary, we should supplement some midnight snacks appropriately. Otherwise, often staying up late and starving will not only affect the quality of sleep, but also produce gastrointestinal diseases and hypoglycemia symptoms, which is not good for your health. Therefore, people who need to work and study for a long time at night must have a full dinner.
