Since the reform and opening up, due to the "Westernization" of the diet structure, "civilization diseases" have spread. Therefore, the current nutritional status of our country is: malnutrition and overnutrition coexist, poverty diseases and wealthy civilization Diseases coexist. In this case, scientific nutrition is particularly important to our nation.
1. Food culture is still "pill culture"
We Chinese people pay attention to dietary therapy, while Westerners are used to taking pills. Our first farming monograph in China, "Essentials for Elevating the People", collects more than 10 categories of cereals and legumes, about 200 species; more than 20 categories of vegetables, more than 100 species; and about 100 species of fish, meat, and eggs. I felt very uncomfortable when I went to Europe. Vegetables are very expensive. A cucumber or a small cabbage costs one euro, or 10 yuan. When I returned to Beijing, I could buy a small cart of vegetables for 10 yuan. China's farming civilization gives us 140 kinds of vegetables to choose from. Therefore, the Chinese nation has formed a traditional dietary structure of the Chinese nation, which mainly eats grains and beans, eats enough vegetables, supplements with animal foods, and also eats fruits. This kind of diet is rich in connotation, has clear health and wellness effects, and also ensures a balanced diet. The Chinese nation's thousands of years of successful practice of ecological agriculture have laid a solid material foundation for "integrating medicine into food" and using food to maintain health.
The Chinese firmly believe that “medicinal supplements are not as good as dietary supplements.” There are six words to evaluate food - color, aroma, taste, shape, container and effect. At the same time, we should pay attention to the "diet therapy" effect. The West is a pill culture. Because Western food has too much animal food and a monotonous variety of vegetables, vegetable intake is seriously insufficient. The per capita vegetable intake in Europe and the United States is 200 grams/day, while the Chinese consume 500-600 grams/day. In order to supplement dietary nutritional deficiencies, the West extracted active ingredients from various foods and made them into pills, forming the modern so-called Western pill culture. Because Americans eat less vegetables, many newborns have developed spina bifida in the past few years. This is due to insufficient folic acid intake in pregnant women. The main source of folic acid is green leafy foods like spinach. The United States later extracted folic acid into tablets and required pregnant women to take supplements. Because Chinese people have a very balanced diet, such congenital malformations are very rare. Another example is vitamin C and beta carotene. They are constantly oxidized from the day they are synthesized, and toxic substances appear when the tablets expire. However, the vitamin C we obtain from food is very stable. A nutritionist once made the following analogy - that is, "pills are man-made, natural foods are created by God."
The West is based on the pill culture and turns good vegetables into pills, because you can’t make much money selling vegetables, you can only make money by extracting them. You will never see advertisements for vegetables and fruits on TV because the advertising fees are added to the product price. An authoritative person in the American health and nutrition community said that in most people's minds, pills of various sizes made in laboratories are panaceas for treating our major illnesses and minor ailments, but this is not the case. Now more and more scientists are developing pharmaceutical resources that are very different from this - namely, animals and plants that have existed on the earth for millions of years and are what we eat with our meals. Because food does not have a simple effect like chemically synthesized drugs, there is no need to worry about side effects. It can maintain the balance of the body and promote health.
Let’s talk about the medical expenditure situation in the United States and related countermeasures.
In 2000, U.S. medical expenditure accounted for 17% of GDP. However, medical insurance only covered 85% of the population, and 37 million people were without medical insurance. Before leaving office, President Clinton warned that if the medical system is not reformed, US medical costs will reach 24% of GDP in 2010, or approximately US$2 trillion. Therefore, the United States rewards "non-drug-related diseases" and specifically lists the category of "nutritional supplementary foods" and divides them into two categories: "foods with potential functionalities" and "functional foods with established functions." The first batch of functional foods with established functions announced by the United States include Chinese soybeans. So we Chinese people say, "You can live without meat for a day, but you cannot live without beans for a day," and "Green vegetables and tofu ensure safety." These are all very correct. The current situation of nutrition in China is that malnutrition and overnutrition coexist. There are 24 million malnourished children in China. Rickets and iron-deficiency anemia are still the main nutritional deficiency diseases in rural areas. In economically developed areas, the diet structure is Westernized, foreign fast food is pervasive, and obesity caused by overnutrition has become a serious problem threatening children and adolescents. "The diet structure is westernized, and the diseases of civilization have landed in China." In 1979, our diabetes prevalence rate was only 0.67%. In 1998, it rose to 3.21%. By 2001, it had reached 6% in Beijing, and most of them were wealthy farmers in the urban-rural fringe. Some farmers use 85 grams of vegetable oil for cooking in one day, and they say it’s okay to eat more vegetable oil. Among people aged 35-74 in my country, the prevalence of hypertension has reached 27.2%, and there are about 130 million people with hypertension in this age group alone.

I will tell you about ways to prevent high blood pressure. One is to drink chrysanthemum tea. You will get certain results after a month of persistence.
The second is to control the amount of salt eaten. Now the average daily salt intake of Beijingers is 15g-16g. If it is controlled below 10g per day (the World Health Organization requires 6g), certain effects will be achieved in a month. When I was a visiting scholar abroad, I once used a method for foreigners, which was to cut a piece of celery into sections half an hour before going to bed every day, blanch it in boiling water, and then squeeze it into juice and drink it. Another "diet therapy" recipe is Gastrodia Uncaria Soup Noodles, which involves boiling 10 grams of Gastrodia elata and 10 grams of Uncaria soup, and then using this soup to play a "diet therapy" role. The so-called diseases of civilization are the "Five Disease Syndrome", which is centered on obesity, high blood pressure, hyperlipidemia, heart and cerebrovascular diseases, and diabetes. About 90% of current diabetes in our country is type 2 diabetes, and the first cause is obesity. Because once the human body becomes obese, it will develop so-called "insulin resistance" and gradually induce type 2 diabetes.
"If dietary misunderstandings are not eliminated, the diseases of civilization are difficult to eliminate." "'Civilized people' have happily swallowed the 'diseases of civilization' and are making graves with their own teeth." The current diet structure of the United States is different from that of the founding of the country. In 1914, the United States conducted a famous experiment in which experimental animals, mice, were allowed to eat animal protein, which was found to promote growth. So-called "non-profit organizations" composed of interest groups put this The results were printed into pamphlets and distributed to all primary and secondary schools in the United States. In 1920, these propagandas were inflated, and the United States gradually changed into the current dietary structure-drinking milk as water and eating a lot of beef. One person consumes 100 kilograms of beef every year. So when did Americans discover there was a problem? During the Korean War, someone conducted autopsies on dead American and North Korean soldiers aged around 20 years old. The results were surprisingly found to be very different in the degree of arteriosclerosis between the two. 77% of the US soldiers had arteriosclerosis. The reason is that differences in dietary structure have planted a "time bomb" in the bodies of American soldiers, greatly increasing their risk of cardiovascular disease and hypertension in the future. Therefore, we think that diseases of civilization are contracted in old age or middle age, and that the root of the disease was taken when we were young. Therefore, we must have a scientific concept and educate our children to pay attention to a balanced diet from childhood. In the past, Chinese people would always ask "Have you eaten?" when meeting someone. Now we probably rarely ask such questions. But now many of us are pursuing "delicious food and taste". Then I think what we should pursue is "eat well and be healthy". "A long belt means a short lifespan. Once you are fat, you will be riddled with all kinds of diseases." "Central obesity" is the worst, which refers to obesity that protrudes from the abdomen, because for every inch of abdominal fat thickening, four miles of blood vessels are added to the body, thereby greatly increasing the burden on the heart. In the West, poor people are obese, which is unthinkable to our ancestors. This is related to the fact that people at the bottom of American society consume a lot of "junk food"-double sandwiches, chicken hamburgers, extra-large pizzas, and large packages of fried potato chips. It is this food structure that makes them the most likely to gain weight in the United States. crowd. As for the above-mentioned "junk food", Chinese people are queuing up to buy and eat it. There is a very strange phenomenon in Beijing. If someone's son, daughter, or grandchild has passed the exam, grandpa, grandma, father, and mother will definitely invite them to eat "foreign food." Rubbish".
Obesity is the second leading cause of death in the United States after smoking. "If you want a child to be safe, you must wait for three times hunger and cold." A few years ago, a hospital delivered two children with different weights. They are 10 pounds and 12 pounds. They are both born with diabetes. Because my mother ate "stupidly", she ended up eating "stupidly". One mother said that I could eat two jins of grapes at a time. Because both of them are only children now, every pregnancy is a priority for protection. Some time ago, we discussed the issue of tainted milk powder. I said that the Chinese have known since ancient times that rice soup is for educating people. After eating ginseng soup and rice oil, children will become fatter and whiter in a hundred days. If the children drink rice soup, they will not turn into a big-headed baby. Why eat fake milk powder? If you want to have good health, you must wait for three points of hunger and cold. Beijing's obesity rate ranks first in the country, reaching 45%, and 20% of newborns in Beijing are obese.

2. Sofa and potato culture threatens people’s health
“Sofa and potato culture threatens people’s health.” In 1997, the World Health Organization issued a report stating that unhealthy lifestyles-sofa and potato culture are threatening human health. (Sofa and potato culture refers to sitting on the sofa, eating French fries, drinking Coke and watching TV). The proportion of Chinese teenagers who watch TV for a long time reaches 12.7%. A survey of teenagers aged 10-15 in the United States shows that the risk of obesity for children who watch TV for an average of 5 hours a day is 5.3 times higher than for children who watch TV for less than 2 hours. A reporter from the American Business Daily used vivid language to describe the business culture represented by fast food, cigarettes, and alcohol that the United States has launched into developing countries around the world. “While the golden logos of fast food restaurants are popular all over the world, the man in the cigarette advertisement is riding a bicycle. Horses appear on the horizon, and advertisements for all kinds of foreign wines are heard all the time.
"When I recall my childhood, I think of the smell of roasted sweet potatoes and boiled corn on the cob. But when our children grow up, they think of "junk food" when they recall their childhood. Comrades, this will be a picture of What a terrible scene!
In the UK, children with "juice drink syndrome" have poor academic performance, are willful, impulsive, hyperactive, and inattentive. They are only better when they get up in the morning because of a night. If you don’t drink fruit juice, you’ll find that “juice drink syndrome” is mostly related to the consumption of artificial pigments. In 1973, the American Medical Association proposed that food additives are related to ADHD in children, and they can cause allergies, such as asthma, laryngeal edema, cough, etc. Rhinitis, urticaria, itchy skin and neurological headaches. Excessive consumption of cola-type drinks can lead to an imbalance in the calcium/phosphorus ratio and affect children's development. During our visit to Europe, we found that all European "cola-opposed" parents do not allow their children to drink cola. , because cola is addictive. Japan's "Yomiuri Shimbun" reported on a Japanese study on March 16, 2004 that the prevention of diabetes should start with diet and exercise. In addition, diabetes in Japan is also called "lifestyle disease". To control your diet, you also need to exercise, so the Chinese say that "a lot of practice is not as good as walking" (To be continued, see the July 1st newspaper "Healthy Express")
3. "Foreign fast food" enters China<. /p>
Junk food is harmful to the health of the Chinese people
"Foreign fast food" has entered China, and junk food is harmful to the health of the Chinese people! Western fast food is an out-and-out "energy bomb" and "junk food" . On February 15, 2002, a reporter from EFE reported from Beijing: "Chinese traditions have been deeply impacted by Western fashions." The article pointed out that "for thousands of years since the Warring States Period, China's ancient traditions have been preserved, but now But it seems that it has succumbed to the irresistible Western lifestyle... From the United States, China imitated the worst thing - foreign fast food. "Foreign fast food" has the three highs (high calories, high fat, high protein) and The characteristics of "three lows" (low minerals, low vitamins and low dietary fiber). Nutritionists have nicknamed "foreign fast food" - called "energy bomb" and "junk food" because eating a meal of foreign fast food will make you lose weight. It is the lower limit of your daily energy consumption. Can you imagine if your child eats bombs every day, will he be healthy? (Applause) "Foreign fast food" also destroys the principle of food biodiversity. It’s simple. It’s not as rich as Chinese food. The Chinese believe that “an omnivore has good food, and an omnivore has nutrition.” U.S. congressmen, nutritionists, and consumer associations claim that obesity, like smoking, has become a public health problem. , calling for "getting fast food out of school." In November 2002, a child in New York who became obese due to long-term consumption of foreign fast food sued McDonald's for causing childhood obesity. (Applause) Published in London on January 29, 2003. "New Scientist" magazine reported that foreign fast food can cause hormonal changes in the body and cause addiction. Professor Michael Schwartz, an endocrinologist at the University of Washington, found that fast food (hamburgers, fried potato chips, etc.) can cause hormonal changes in the body, making it difficult for eaters to control it. Food intake. The article said: "The discovery of the biological effects of fast food has explosive significance. The cause of obesity cannot be attributed to obese people's lack of self-control."
The oil used in some "foreign fast food" is different from the ordinary vegetable oil traditionally used in China, because it uses hydrogenated oil, that is, oil produced by hydrogenating vegetable oil. Professor Willett, chairman of the Department of Nutrition at the Harvard School of Public Health, pointed out in 1991: Hydrogenated oil produced by hydrogenating natural vegetable oils is harmful to health! Because hydrogenated oil contains some trans fatty acids that do not exist in nature, trans fatty acids can affect the human endocrine system and harm health. "Epidemiological studies on the relationship between hydrogenated fat intake and the risk of heart disease and diabetes show that hydrogenated fats are worse than saturated fats," Willett noted.
Foreign fast food and carcinogen-C poison. On April 24, 2002, the Swedish National Security Administration announced the latest research results, which found that French fries, hamburgers, crispbreads, roast pork, etc. contain a large amount of acrylamide. Because acrylamide damages the central nervous system, it can induce benign or malignant effects. Tumors, so some scholars believe that this explains the high incidence of tumors in Western countries. The U.S. Drug and Food Administration (FDA) announced the inspection results of 750 types of food on March 24, 2004, and once again confirmed that French fries, potato chips, popcorn, and fried chicken have the highest levels of this type of carcinogen. Home-cooked dishes are in better condition, and fresh vegetables are the safest. Europe and the United States are different from China. Every kitchen has an oven, which is used for high-temperature cooking. Traditional Chinese meals are cooked at low temperatures. Our rice, noodles, and steamed buns are all made with water as the medium. The temperature will not exceed 100 degrees Celsius, which is much lower than baking. . Stir-fried dishes are completed in a short time, and the cooking method of combining high and low temperatures is not only beneficial to maintaining nutrients from loss, but also meets the need for surface sterilization and reduces the oxidation of oil. So the traditional cooking methods of the Chinese people are very safe.

4. Guide the whole nation to consume food scientifically and rationally
The wrong direction of "foreign fast food" has caused a sharp increase in meat consumption, endangering the survival of the Chinese nation! From 1988 to 1998, China's meat consumption doubled, and some people told me that their children have become "carnivores." Our meat consumption has surpassed South Korea and Japan, becoming the first country in Asia to maintain oriental eating habits. Our pork consumption ranks first in the world. From a short-sighted perspective, this seems to indicate an improvement in living standards, but from the perspective of ecology and sustainable development From a human perspective, excessive meat consumption will endanger the survival of the nation. As we all know, the production of one pound of pork and poultry requires 3 times and 5 times the input of grain. One acre of land used to raise cattle can produce 1 pound of animal protein, and growing soybeans can produce 17 pounds of high-quality plant protein. Eating meat requires 16 times more land than beans. The water consumption of livestock breeding is eight times that of growing vegetables and cereals, and its pollution and damage to the ecological environment is no less than industrial pollution.
The State Council recently announced China’s 64th occupation. A new occupation called nutrition caterer has emerged in my country to ensure people’s health. Comrade Yu Ruomu once pointed out: "Scientific catering is an effective way to improve people's health conditions without investment." Due to our vast territory and large population, coupled with the unbalanced development of economy, culture and productivity, especially due to the imbalance of dietary structure Balance, leading to both malnutrition and overnutrition. Through scientific meal preparation, various diseases caused by malnutrition can be effectively controlled. In order to avoid repeating the mistakes of developed Western countries, we believe that it is an urgent historical task to adjust the structure according to national conditions and guide the entire nation to scientifically and rationally consume food.
From the practice of fighting against nature, the Chinese people realize that many foods have medicinal properties. "Zhou Li? Tianguan Pian" records that as early as the Western Zhou Dynasty 3,000 years ago, my country established the world's earliest medical system, and the medical system already had full-time personnel responsible for diet and nutrition management. At that time, doctors were divided into four categories, namely "food doctors"; "disease doctors" (physicians), who used "five flavors, grains, and five medicines to nourish their illnesses"; and "surgeons" (surgeons), who "used acid to nourish bones" , use pungent to nourish tendons, use salty to nourish pulse, use bitter to nourish qi, use sweet to nourish meat, use smooth to nourish orifices”; and “veterinary medicine”. The medical system of the Zhou Dynasty prioritized "food medicine", and the task of "food medicine" was to "control the six foods, six drinks, six meals, one hundred delicacies, one hundred sauces, and eight delicacies". That is to harmonize food taste, determine the four seasons of diet, and prevent diseases. This is the earliest practice of "nutritional medicine" in mankind so far.
Famous doctors in the past dynasties of China have many discussions on the importance of diet: For example, during the Warring States Period, Bian Que said: "When a gentleman is sick, he should first treat it with food. If the disease cannot be cured by food therapy, he will then take medicine." Huang Gongxiu of the Qing Dynasty It pointed out: "The food ingested is the same as the medicine used to treat diseases. If the combination is beneficial to the internal organs, it can cure diseases and health; if the food is not combined, it will be harmful to the human internal organs, which will increase the disease and promote death." Sun Simiao of the Tang Dynasty pointed out: " Food is the foundation of survival, and those who do not know how to treat food are not good enough for a healthy life." "Food can expel evil spirits and calm the internal organs, and it can cheer up the mood and refresh the mind and nourish the qi and blood." "As a doctor, you should know the source of the disease, and treat it with food if it is caused by it. If the disease does not heal after eating, then prescribe medicine."
The philosophical connotation of traditional nutrition of the Chinese nation:
" The ecological view of "the unity of nature and man, and the unity of body and soil";
The health view of "regulating yin and yang, yin and yang secrets";
"medicine and food come from the same source, and medicine is integrated into food" "The concept of dietary therapy;
The concept of balanced diet of "evaluating the causes and providing meals based on syndrome differentiation".
Therefore follow: "Light diet, mainly vegetarian food";
"You can live without meat for a day, but you cannot live without beans for a day";
"Lack of food, light food, "Green vegetables and tofu keep you safe";
"You can't eat without greens."
There is a folk proverb in the Nanjing area: "If you don't eat green food for three days, your eyes will shine with stars." These dietary principles of traditional Chinese health care are very valuable.
The World Health Organization recommended the "Mediterranean diet" in the 1990s. Residents living in Italy, Spain, Greece and other countries around the Mediterranean Sea have roughly the same environment as those in Northern Europe. The incidence of heart disease is higher. But it is very low, and it is one of the longevity areas in the world. Studying this phenomenon has given people a lot of inspiration. After extensive investigation and analysis, the mystery was gradually revealed, and it is believed that this is related to the dietary structure of the region (Mediterranean diet). The basic characteristic of the "Mediterranean diet" is "omnivore", which organically combines cereals, meat, seafood, eggs, vegetables and fruits, starch-rich cereals and vegetable paste seasonings, plus a large amount of green leafy vegetables and fresh Fruit, small amount of meat. The food is diverse and nutritious, meeting the body's comprehensive nutritional needs. The "Mediterranean diet" fully embodies the principle of biological diversity and effectively reduces the occurrence of cardiovascular diseases. One vegetable they often eat is purslane, a wild vegetable eaten by Chinese folk.
McGovern, chairman of the U.S. Senate’s Special Committee on Nutrition and Health, submitted a report to Congress stating: “The current nutritional problem, or nutritional imbalance, overnutrition, and nutritional quality have become the primary issue related to people’s health. The problem today is that the danger is not beriberi, pellagra, or scurvy. The reality we face is much more subtle and terrifying. What millions of Americans are putting in their bellies is likely to make them obese. , high blood pressure, heart disease, diabetes, cancer. In a word, it will kill slowly. This was his sharp criticism of the American dietary structure at that time. "So in 1996, the United States Department of Agriculture launched the "Food Guide Pyramid". Suggestions on the variety and quantity of food you choose every day are designed to promote health and reduce the occurrence of heart disease, high blood pressure, cancer, diabetes and other diet-related diseases. As early as the autumn of 1992, after this graphic was released, it was immediately criticized by meat and dairy manufacturers on all fronts, believing that it did not meet the living needs of Western residents. After spending US$860,000 and completing further verification, it was confirmed that the design of the "Food Guide Pyramid" was scientific. In the pyramid promoted by the United States, the first to last layer is composed of whole grains; the second to last layer is evenly divided between vegetables and fruits; the third to last layer is half dairy products and half meat, poultry, fish, eggs, nuts and dried fruits; the top layer is Oil, salt, sugar. Do you think this is American food? It is not difficult to see from the picture that the "Food Guide Pyramid" is a replica of the Eastern dietary structure that has existed for thousands of years. Nutritionists believe that changing the Western food structure can extend the average life span of Americans by 10 years.

5． The Chinese nation
There are ten major balances in diet and dining
The Chinese nation has ten major balances in diet and dining. The traditional Chinese dietary structure emphasizes "balanced diet and syndrome differentiation" and advocates the complementarity of foods with different nutritional components. There is an incisive discussion about the traditional dietary structure of the Chinese nation as follows: "Five grains are suitable for nourishment, and missing beans is bad. Five livestock are good for good, and too much will be harmful. Five vegetables are always sufficient, fresh green, yellow and red, and five fruits should be for help." , strive to be in small quantities, take them when the smell is suitable, especially avoid being alone, eat in a moderate way, and never eat too much. "Only in China, food can be divided into staple food and non-staple food. During the SARS period last year, I did it on the radio. The program repeatedly emphasizes acid-base balance. The pH value of SARS virus culture medium is 7.2, while the pH value of human blood is 7.35 to 7.45. If you eat too much acidic foods such as chicken, duck, and fish. When the blood becomes acidic, you are more likely to be infected with SARS.
Our Chinese characters are all symbols of wisdom. We say that a person's good health means having "jing, qi, and spirit." Half of the word "jing" is rice and the other half is vegetables. If you don't eat rice, how can you get the essence if you don't eat vegetables? The traditional Chinese character for "qi" also contains rice. " Half of the word "神" refers to fields and crops are grown on them. Therefore, if you don't eat plant substances, you will have no "essence", no "qi", and no "god". The Chinese nation is known as "the rice of all things in the world" The ancestral motto of "precious". Our sages have deeply realized the huge health effects of whole grains--the staple food from life practice. The Chinese people have drawn from practical experience that "eating grains cures all diseases" and "rice porridge and rice warm The conclusion of "Stomach Nourishing Qi". "Suju Ju Food Spectrum" states: Porridge and rice are the most nourishing things in the world. Poor people suffering from deficiency syndromes can use thick rice soup instead of ginseng soup, which always achieves miraculous results. For patients who are pregnant, porridge is the best way to nourish the body. Li Shizhen said , Rice oil is the poor man's ginseng soup. "If you eat rice oil, you will become fat and white after a hundred days." Traditional Chinese medicine believes that brown rice is sweet in taste and warm in nature. The balance between the essence and coarseness of staple food is the simplest and most feasible method used by modern nutrition to guide people to scientifically arrange their meals. Confucius pointed out in "The Analects of Confucius? Xiangdang": "Although there is too much meat, it does not make the food lose its energy." Moderate amount of meat means that even if the daily diet is rich in meat, we should not eat more meat than the staple food. Last year, a director visited me and said that his child had become a "carnivore", so how much should he eat? What is the right amount of meat? I said how many teeth do you have? He said 32. I said if you were a tiger, your mouth would be full of sharp teeth. The eight teeth in front of us humans (such as incisors, etc.) are called incisors. They are used for cutting fiber; the 20 teeth at the back are molars, used for grinding grain; only four canine teeth are used for eating meat. Is it appropriate for you to eat so much meat? The ratio of molars to incisors = 5 to 2 to 1. , the ratio of plant-based foods to animal-based foods in the normal human food structure should be 7 to 1! It is this mysterious ratio that highlights the importance of plant-based foods to human health. The result of millions of years of natural human evolution. The incidence of prostate cancer remains high in the United States, and has also shown an increasing trend in China in recent years. An epidemiological survey of the Mongolian people in pastoral and agricultural areas of the Inner Mongolia Autonomous Region found that they mainly eat meat. In pastoral areas, the incidence of prostatic hypertrophy in male adult residents is much higher than in agricultural areas, indicating that dietary structure is related to the incidence of prostate diseases. Since the fat of four-legged terrestrial animals contains arachidonic acid (the precursor of prostaglandins), It can be seen that the diet structure is westernized and excessive meat consumption is one of the reasons for the obvious increase in the incidence of prostate cancer.
It is better to eat four legs than to eat two legs, and to eat two legs is not as good as one leg, such as one. Leg mushrooms are healthy food.
British and American scientists have discovered that the composition of the microbial flora in the intestines of vegetarians and non-vegetarians is significantly different - when human digestive juices interact with the above-mentioned intestinal microorganisms, the chemicals produced are also different, which causes non-vegetarians to be more prone to cancer. The traditional dietary structure of the Chinese nation advocates diversification of food sources, which is comprehensive, dominant and compatible. It is suitable for the physiological structure of the human digestive tract and the comprehensive nutritional needs of the human body. Micronutrients such as trace elements can only be ingested from the outside world and cannot be synthesized or produced by the body itself. The importance of omnivorous food is self-evident. Professor Li Ruifen, a famous nutritionist, advocates that in order to maintain physical fitness, you should eat more than 30 different types of food every day.
Food also has four properties: cold, hot, warm and cool. Therefore, just like traditional Chinese medicine, a balanced combination can be beneficial to health. Mung bean is cold in nature and non-toxic, clears away heat and detoxifies, produces fluid and quenches thirst; chrysanthemum is bitter and non-toxic, clears away heat and improves eyesight; watermelon is known as "Shengsheng Baihu Decoction" and is used for fever, thirst and red urine. Mutton is sweet, bitter, hot, non-toxic, nourishes deficiency and dispels cold, and has the same effect as ginseng. Chinese people like to drink mung bean soup, chrysanthemum tea, and watermelon as an after-dinner fruit in summer; in winter, they like to eat boiled mutton; crabs are cold in nature, while ginger is hot in nature. When eating crabs, minced ginger is eaten. Disrupting the balance of cold and heat in the four properties of food during ingestion is naturally detrimental to health. This kind of food selection and matching is based on the understanding of dietary balance.
The five flavors of food are sweet, sour, bitter, pungent and salty. The five flavors can be harmonized to increase appetite and complement each other. 2,500 years ago, the ancient medical book "Huangdi Neijing" elaborated on the dangers of excessive salt consumption. The results of the National Hypertension Sample Census in the 1990s showed that about one-fifth of the population in Beijing suffers from hypertension. Corresponding to the eating habits of "sweet in the south and salty in the north", the prevalence of hypertension changes regularly and shows a clear downward trend from north to south. Among the big cities, Beijing>Tianjin>Shanghai>Guangzhou. The prevalence of hypertension in Beijing is 4.4 times that of Guangzhou. Therefore, changing heavy eating habits and scientifically arranging meals are important means to control high blood pressure. Shandong farmers eat 17.3 grams of salt every day, and the prevalence of hypertension is 15.3%. Guangxi farmers eat 7.5 grams of salt every day, and the prevalence of hypertension is only 8.2%.
"Eating should be done carefully and slowly, not coarsely", a balance between fast and slow eating speed. The book "Yongyan for Nurturing Diseases" says: "Whether it is porridge, rice or snacks, it is advisable to chew them very carefully and swallow them." It is recorded in "Yishuo": "Don't eat in a hurry. Being in a hurry will damage the spleen. The method should be to chew carefully and thoroughly." The patient is required to chew each mouthful of rice 50 times before swallowing, which is beneficial to the body's recovery. Chewing is an important part of helping food intake and digestion. Chewing slowly when eating can cause a large amount of saliva to be secreted. The amylase in saliva can aid digestion, and lysozyme and secretory antibodies can sterilize and detoxify. Saliva has the magical effect of converting carcinogens into harmless substances - such as: nitrosamines, aflatoxins, 3,4-benzopyrene and alkylating agents, smoke oil, fish and seafood burns, etc. Its mutagenicity to cells can be completely lost within 30 seconds. When you chew it carefully, you provide our body with the first line of defense.
"Eat warm" and pay attention to the balance of hot and cold in meals. Sun Simiao's discussion in "Qian Jin Yifang" is worthy of reference. He pointed out that "hot food hurts the bones, cold food hurts the lungs, hot food does not burn the lips, and cold food does not ice the teeth." Why do so many children cough in summer? Eating a full stomach of ice cream lowers the temperature of the stomach and lungs at the same time. The capillaries are constricted and blocked, and of course a cough will occur.
"Eat in time", meal time and the balance between hunger and fullness also need to be paid attention to. "Eat one less bite for dinner, and stay comfortable all night." Nowadays, many people are obese because they socialize at night and go back to bed after eating. Sleeping after eating is the life of a pig, so it is very easy to become obese. (Applause)
In addition, special emphasis needs to be placed on the balance between food intake and physical activity. The key to obesity is taking in too many calories and consuming too few. Everyone must pay attention to exercise. When you climb stairs, you consume 0.1 kcal when you go up a step, and you consume 0.06 kcal when you go down a step. Therefore, exercise is the most important nutrition - behavioral nutrition. There is a famous saying in Greece: "Do you want to be healthy? Run, do you want to be smart? Run, do you want to be beautiful? Run." We believe that exercise is behavioral nutrition. Therefore, it is proposed that psychological nutrition, food nutrition and behavioral nutrition are the most important to human beings. Hippocrates stated: “We should use food as medicine, and diet as your first choice of medicine.” This coincides with our traditional Chinese medicine theory of "integrating medicine into food".
