The so-called nutrition, as the name implies, is to create, choose and create, and nourishing is to preserve health and live longer. Therefore, the concept of nutrition can be interpreted as the process that the body ingests food, digests, absorbs, metabolizes and excretes it, and uses nutrients and other beneficial components (non-nutrients or phytochemicals) in food to build tissues and organs, regulate various physiological functions, and maintain normal growth and development, disease prevention and health care. Believe this, everyone can do it. Because of the need of chronic disease prevention, society gave birth to the profession of dietitian. Doctors' job is to cure diseases and save lives, but the problem is that no one wants to be critically ill or seriously ill. However, the occurrence of any disease cannot be achieved overnight, and prevention has become the top priority. Doctors can't always warn that this is inappropriate and harmful to health. Personal awareness and behavior are crucial. There is a cloud in Huangdi Neijing: "Therefore, the disease that the sage has not treated is also", "The sage will do what he says, and the fool will admire it." Treatment depends on doctors, and prevention depends on yourself. Health preservation is something that everyone can do, not an inscrutable academic term.

A hundred years ago, people didn't need nutritionists. A lot of human energy is used to deal with bacteria, viruses, war wounds, external sentimentality, diseases caused by disasters and so on. Doctors save lives, angels in white. With the development of society and the progress of science and technology, the ability of human beings to resist natural disasters is becoming stronger and stronger. Many diseases considered as terminal diseases have found good ways and means to deal with them, and the level of medical science and technology is not the same, such as smallpox and leprosy, which have basically disappeared. However, people's lives have improved, but new diseases have not been eliminated. We are no longer faced with old diseases such as viruses, bacteria and war wounds, but a new disease that is little known-chronic diseases. In modern society, chronic diseases can easily become the most harmful of all diseases. They quickly left smallpox, leprosy and other diseases that people once feared like tigers and leopards behind, ranking first among all kinds of diseases that endanger human beings, such as hypertension, tumor, diabetes, rheumatism, cardiovascular and cerebrovascular diseases and so on. The terrible thing about these diseases is that they planted the root of the disease in a silent state until it was too late to be discovered.

Doctors who specialize in chronic diseases are also at a loss. We already know that chronic diseases have many harmful factors to the human body, which cannot be solved by a single drug, and nutritionists just naturally undertake the work of preventing and treating chronic diseases. Dietitians have become the primary level to intercept chronic diseases.

In 2006, the Ministry of Health of China announced the main causes of death of urban and rural residents in 2005. Chronic diseases, malignant tumors, cerebrovascular diseases and heart diseases are the top three causes of death for urban and rural residents, while the top three causes of death for rural residents are respiratory diseases, cerebrovascular diseases and malignant tumors respectively. Experts say that chronic diseases have become the heaviest disease burden in China.

According to the survey, there are several reasons for the above problems:

First, although most people are concerned about nutrition, they still lack the necessary nutrition knowledge. Therefore, overnutrition of urban residents and malnutrition of rural residents coexist.

Second, there is a lack of nutritionists to guide a nutritious diet.

When people are confused about the source of chronic diseases, they find that the root cause is themselves, and malnutrition has become the most important core factor. The best way to prevent chronic diseases is to treat them early. When medical treatment becomes impossible to treat chronic diseases, nutritionists play a more important role in preventing diseases than ever before.

Linus pauling, a two-time Nobel Prize winner, has high hopes for nutrition, saying that nutrition should be the medicine of the future. At the beginning of the 20th century, Edison thought that doctors in the future would not give drugs to patients, but would guide patients to pay attention to the human body structure, the maintenance of diet and the causes and prevention of diseases. I believe that in the future society, everyone is a health expert and a nutritionist. They don't rely on doctors to get health protection, but rely on themselves to choose good health habits to get health and happiness. Dietitians have gradually become a new profession.

The emergence of public nutritionists in China stems from the following aspects.

1, China residents can't eat and eat many chronic diseases because of lack of nutrition knowledge guidance. The incidence of chronic diseases such as hypertension, diabetes, obesity and childhood asthma is on the rise, and it is younger. According to the data of the Ministry of Health, as of 2002, the prevalence rate of hypertension among residents aged 18 and above in China was 18.8%, and it is estimated that the number of patients in China was more than 654.38+600 million. Compared with 199 1 year, the prevalence rate increased by 3 1% and the number of patients increased by about 70 million. According to statistics, the turnover of catering industry in China exceeded 600 billion RMB in 2003 and 700 billion RMB in 2004. The development of catering industry has promoted China's economic development, but the incidence of chronic diseases eaten by the public is really surprising. Hot pot and foreign fast food ranked first and second in the sales of catering industry respectively. According to the survey, the incidence of parasitic diseases, childhood asthma, gout, cholecystitis and pancreatitis has increased due to the unreasonable quantity or method of eating hot pot, even several times higher than that of ordinary people. Children's obesity is directly related to the large intake of foreign fast food.

2. The public's nutrition is related to China's economic development. The incidence of chronic diseases is increasing year by year, which leads to high medical expenses for the country and the public. At the same time, because of physical illness, it affects people's working ability and intelligence, and directly affects social and economic development. Only during the SARS period, the CDP in China dropped by 0.5 percentage points.

3. Global employment and entrepreneurial market demand. Japan and other developed countries have one nutritionist for every 300 people. China has a population of 65.438+0.3 billion, and there are less than 3,000 registered dietitians. Moreover, some of them are retired, and some are clinical nutritionists in hospitals who are engaged in the treatment of diseases. However, schools, enterprises and institutions, fitness centers, kindergartens, communities and other places that need to popularize nutrition knowledge generally lack relevant nutritionists. Only meet the needs of domestic nutritionists. About 4 million nutritionists are needed. Some nutritionists with knowledge and skills of Chinese and western medicine nutrition are favored by the international nutritionist market. Therefore, the training goal of public dietitians in China far exceeds 4 million. The emergence of the public dietitian profession has promoted the development of employment and entrepreneurship in China.

4. Professional elements are unified with international academic viewpoints on nutrition. According to the characteristics of social demand for nutritionists, the demand for new professional nutritionists is wide, mainly in places other than hospitals such as schools, enterprises and institutions. Mainly a dietitian in public nutrition. 1in July, 1997, a symposium on the conceptual framework of public nutrition was arranged before the 16 international nutrition conference. Participants believe that public health and nutrition and international nutrition cannot cover all types of nutrition problems today, so it is necessary to determine new disciplines. Public nutrition. Public nutrition is an independent discipline and a part of nutrition. Public nutrition is to discover the nutritional problems in the population through nutrition monitoring and nutrition investigation, which is also conducive to the scientific theory of nutrition research and improve the nutritional problems in the population. In 2004, the survey report jointly issued by the Ministry of Health, the Ministry of Science and Technology and the National Bureau of Statistics showed that the nutritional health status of Chinese residents was not optimistic. The incidence of chronic diseases such as hypertension, diabetes and hyperlipidemia related to diet increased year by year, and the age of patients continued to decline.

On World Health Day in 2005, the dietary status of kindergartens, schools, communities and residents' families was investigated by focus interviews. The survey found that although the dietary nutrition status of urban and rural residents in China has obviously improved, at the same time, China is also facing the dual challenges of nutritional deficiency and unbalanced nutritional structure.

China is considering the introduction of the first national nutrition regulation (draft), which clearly stipulates that all kindergartens and schools, and even communities, should be equipped with professional nutritionists. In today's increasingly integrated world politics, economy, culture and education, talents can only strive for a broader development space if they are in line with international standards.

Refinement of nutritionist training. With the continuous expansion of the nutritionist training market, nutritionist training is gradually refined to meet the social demand for nutritionist positions. There are already training programs for children's nutrition managers, beauty nutrition managers and health education instructors. A nutritionist is a nutrition professional who can guide people in the fields of diet, disease prevention, adjuvant therapy, sub-health prevention and health management. Through strict basic nutrition theory study and professional clinical nutrition skills training, and can design good programs and follow-up services. In the legislation of the nutritionist law, there will be qualifications for obtaining a skill certificate.

Broadly speaking, it refers to professionals engaged in nutrition work, who not only have rich nutrition professional knowledge, but also have certain nutrition-related work experience and accumulated certain experience, and have rich professional qualifications in this industry. Nutritionists are also divided into clinical nutritionists, public nutritionists, food nutritionists, sports nutritionists and catering nutritionists because of their combination with different objects. Clinical nutritionist: Mainly engaged in nutrition related to diseases, making reasonable meals for patients and designing recipes suitable for different patients. She mainly works in a hospital and is often called a nutritionist. Most of these nutritionists graduated from the preventive medicine department of medical college/university. Public nutritionist: also known as public nutritionist, whose work is related to the public, mainly engaged in the dissemination of nutrition knowledge, group nutrition survey, planning of various nutrition-related social activities, and planning of film and television documents related to nutrition knowledge publicity and education. Its work content is mostly intangible products such as nutrition knowledge. Food nutritionist: mainly working in food enterprises, mainly responsible for food-related nutrition work such as food development. Sports nutritionist: A nutritionist, professional athlete or sports enthusiast who provides nutrition guidance for athletes. Compared with ordinary people, they exercise more and their nutritional needs are quite different from ordinary people. Therefore, the nutrition of this group of people has special requirements and should be carried out by professional sports nutritionists, which is beneficial to their health. Catering nutritionist, mainly engaged in catering-related nutrition work, such as nutrition catering plan, nutrition recipe formulation, nutrition catering personnel training, catering service personnel training, etc. Medicinal diet nutritionist, serving food and drug companies, market associations and catering service providers. Dietetic nutritionists assist business leaders to conduct research, put forward professional opinions on management and market, and urge enterprises to produce better medicated health food on the market. It can also be divided into more detailed nutritionists according to the nature of work, such as beauty nutritionists, health care nutritionists and so on.
