On the discussion of diet, although people are advanced animals, they still have to "eat" like ordinary animals. As a result, a variety of dazzling foods were born, and they have been enduring since ancient times. Let's see what we have discussed about diet.

On diet 1 Our traditional diet has the characteristics of "fourfold";

1, heavy food: The ancients said, "Food is the most important thing for the people", and when they meet, they often ask, "Have you eaten?" It can be seen that the status of food culture.

2. Re-feeding: feeding "six viscera" with "five grains" and paying attention to human health care in diet.

3. Emphasis on taste: China pays the most attention to the taste of food, paying attention to "color, aroma, taste and shape". The differences of various tastes form the basis of various cuisines.

4. Pay attention to management: pay attention to the collocation of various foods, and guide cooking with the rational understanding of harmony between Yin and Yang, such as mutual restraint and complementarity.

It is precisely because China pays attention to the delicacy of ingredients, cooking and eating. , its content is rich and profound, with distinctive national characteristics, both compatible and special. From ancient times to the present, it has been passed down from generation to generation, bringing forth the old and bringing forth the new.

Different eating habits have created different food cultures. China People's Congress's consistent style is that when eating, it is naturally seven big plates and eight big bowls. One is to show wealth, the other is to put on enough ostentation and extravagance; In recent years, compared with the way of eating all over the country, the whole country is competing for supremacy, and finally eight major cuisines have been formed, that is, eight different "masters" in eating methods; Although a bit vulgar, it is still very expressive.

Therefore, the deep connotation of China's food culture can be simply summarized into eight words: exquisite, pleasing to the eye, devoted and polite. These eight words reflect the unique cultural implications of food quality, aesthetic experience, emotional activities and social functions in the process of food activities, and also reflect the close relationship between food culture and Chinese excellent traditional culture.

Exquisite; When we are proud, we all like to order some exquisite dishes in pubs and restaurants, or make some exquisite dishes to treat ourselves and our relatives and friends, and then we need to eat an atmosphere, a taste, and even a culture. Since diet is a kind of culture, a kind of "eating" culture, and quality consciousness is a kind of cultural spirit, it is more and more widely and deeply infiltrated and implemented in the whole process of diet activities. The selection of materials, cooking, compatibility and even the dining environment all reflect "exquisiteness". Especially in the modern society, which attaches great importance to personal health care, it is required that our diet should be refined, so that culture can be integrated into the diet and displayed, so as to "eat" the culture and avoid and abandon the indecent behavior of "munching on the door" and bad habits harmful to health.

Pleasant to the eye; This is an advanced stage to sublimate the culture and connotation of "eating", which embodies the aesthetic characteristics of food culture. One of the important reasons why Chinese food can conquer the world lies in its beauty, which makes consumers feel "I don't know the taste of meat in March" and is more amazing and pleasing to the eye. This kind of pleasing to the eye refers to the perfect unity of the form and content of China's food activities, and refers to the aesthetic pleasure and spiritual enjoyment it brings to people, first of all, the delicious taste. Dr. Sun Yat-sen once said that "if you don't know the taste, your cooking will be poor", and regarded the aesthetics of "taste" as the first essence of cooking.

Delicious food, as the basic connotation of food culture, is the charm of China food, which runs through every link of food activities.

Fall in love; This is a summary of the social and psychological functions of China's food culture. Because there are all kinds of feelings in cooking and eating. People who cook devote themselves wholeheartedly, and people who eat taste their favorite food with gratitude and appreciation. Eating and drinking can not be simply regarded as a medium of emotional communication between people, but a unique social activity. Chatting while eating, doing business, exchanging information and interviewing. When friends leave, people are used to expressing farewell or welcome at the dinner table, and emotional turmoil is often calmed down by the dinner table. This is the regulating effect of dietary activities on social psychology. In the past, it was an excellent psychological massage for everyone to sit down and drink tea, listen to books, put on a dragon gate array or vent their dissatisfaction with the court.

The reason why China's diet has the function of "lyricism" is because of the philosophy of "drinking morality, eating harmony and enjoying all the people" and the resulting diet with national characteristics. For the emotional culture in food activities, there is a problem of guiding and improving the taste. We should advocate healthy, beautiful and enterprising cultural sentiments and pursue noble sentiments.

Politeness; Refers to the etiquette of eating activities. China is a country of etiquette, and this etiquette and the way of governing the country are also permeated in the diet. And the diet pays attention to "etiquette", which has a lot to do with our traditional culture. This is a ceremony of being born, sick, seeing off, welcoming, worshipping God and ancestors. Book of rites? Li Yun said: "At the beginning of the ceremony, all kinds of food and drinks began." "Li" also pays attention to a kind of order and norms, such as the seating direction of important occasions, the placement of chopsticks and spoons, the order of serving, the symbols and origins of certain dishes, etc. All embody "courtesy".

When we talk about "etiquette", we should understand it as a kind of spirit, an internal ethical spirit, which runs through the process of food activities, thus forming the logical starting point of China's food civilization.

Exquisiteness, pleasing to the eye, devotion and courtesy in diet summarize the basic connotation of China's diet culture from different angles. In other words, these four aspects organically constitute the overall concept of China's diet culture. However, they do not exist in isolation, but are interdependent and mutually causal. They are intertwined and perfectly unified, which constitutes the highest realm of China's food culture. Chinese food is also a culture that the Chinese nation has "eaten" with its mouth since ancient times. It is a strong Chinese food culture, which has been continuously promoted, affecting ourselves, our side and the catering industry all over the world.

Discussion on diet 2 1. Unhealthy eating habits

In modern society, where people often don't have enough to eat, everyone pays great attention to shaping and losing weight. Some people are hungry for a long time or have insufficient diet, or take too few nutrients in order to get better. These bad practices will lead to emaciation and fatigue, and serious will lead to various nutritional deficiencies. Su Wen in Neijing once pointed out: "If you don't go into the valley, you will be weak for half a day and lose one day." Insufficient diet, especially the lack of protein and heat energy, makes the body in a negative nitrogen balance, constantly consumes protein in the body and converts it into heat energy for demand, which will cause metabolic disorders, growth and development disorders, low immune function and lead to malignant malnutrition. If some nutrients are lacking for a long time, it will cause various nutrient deficiencies.

Overeating and frequent overeating will not only affect the digestion and absorption function due to the heavy burden on the stomach, but also lead to overnutrition and cause diseases. Overeating or long-term satiety can cause digestive tract dysfunction. Overeating and obesity, nutritional imbalance, partial overnutrition, accumulated in the body, causing metabolic disorders, which can produce hyperlipidemia, hypertension, diabetes, obesity and so on. Su Wen in Neijing said that "the change of sorghum can give birth to great cure" and "a thousand daughters should cure the staple food" and that "excessive phlegm when the husband is in the body is caused by improper diet", which mostly refers to overeating or being too fat and too sweet to cause disease.

Excessive partial eclipse or partial eclipse will lead to malnutrition and metabolic disorder, which will lead to various diseases. Similarly, overeating can also cause overnutrition or affect the function of various organs. For example, people who like to eat snacks are prone to intestinal dysfunction. Because snacks contain more sugar and fat and lack protein and vitamins, it will cause malnutrition or vitamin deficiency. For example, people who prefer to eat salty food will have high blood pressure due to the increase of osmotic pressure of extracellular fluid, the increase of plasma volume in blood vessels and the increase of vascular resistance, or edema due to the overload of kidneys. For example, people who like to eat meat and fish will consume too much cholesterol, leading to arteriosclerosis and vascular sclerosis. However, vegetarians are easy to lack trace elements and vitamin B 12. It has been discussed in Su Wen of Neijing that "if you eat more salty food, your pulse will be coagulated and discolored, and if you eat more bitter food, your skin will rise and pull out ...", many of which have been confirmed by modern science.

Often eat cold food or raw food. The ancients have long noticed that eating cold food is an important cause of human illness. Since the fire was discovered, they began to advocate eating cooked food. For example, as recorded in the Book of Rites, in ancient times, "the meat of birds and animals containing grass was not cremated, and blood was like its hair", but "Suiren began to drill wood for fire, and the cannon was cooked, which made people have no intestinal diseases". Therefore, the cooking treatment of diet is an important aspect to reduce diseases. Raw food, especially fish, is not only easy to make people sick because it contains germs or parasites, but also difficult to be digested and absorbed, damaging the stomach. Cold food not only stimulates the stomach, leading to indigestion, but also easily induces diseases such as cough and asthma.

Eating too fast or eating too much soup food too fast increases the burden of eating because the food fails to give full play to the digestive function of saliva, which often leads to inflammation or ulceration. For example, soup will burn taste buds and lead to loss of appetite. Tumors in oral cavity and esophagus will affect digestion and absorption due to blood circulation disorder, which often leads to loss of appetite and digestive dysfunction.
