What Are the Pros and Cons of Choosing a Dietitian Major?

Nutrition is a discipline that studies the relationship between body metabolism and food nutrients. By describing the history, origin, development, characteristics, and levels of nutrition, you can know the development of nutrition. Nutrition has a profound impact on society, families, industries, health, and policies. The United States is the representative of nutrition in the molecular field, China is the representative of holistic nutrition, and Japan has both characteristics. Although Japan is not a developed country in nutrition science, a 2015 survey found that Japanese clinical nutrition science has established a system. Since the 21st century, the use of various ripening agents has made food nutrients deficient, and the nutritional status of the people is worrying. These are issues that deserve attention.

There are five levels of nutrition.

The first is the material level, that is, the various foods mentioned in Chinese medicine are divided into cold / heat / equal categories. Dae Jang Geum is a master in this area. Detailed functional memory and matching of plants and food / animals. Need experience.

The second is the level of nutrient elements, that is, western nutrition. Anatomize the microstructure of the nutritional components and clarify the function of each element. But it is easy to disassemble the whole / system and understand the substance independently / isolated.

The third is the level of chemical structure, that is, the detailed description of the structural composition of elements and the role / process of human body structure. Deeper into the tiny areas.

The fourth is the level of molecular atom research, which explores the molecular / atomic structure of the constituent elements.

Nutrition can generally be divided into diet nutrition,

The concept of physiology, nutrition, and health of modern nutrition is gradually affecting and changing the view of life and diet of people in need of health. There is no doubt that its development and application, and its role and impact on future society are huge. However, the development and application of nutrition must be adapted to the level of social and economic development, so as to reflect its influence. The following is a brief history of contemporary nutrition development.

A Brief History of the Development of Modern Nutrition

I. Global Progress Record

In 1910, German scientist Fischer completed the determination of a simple carbohydrate structure.

In 1912, Polish scientist Funk proposed the concept of vitamins and extracted nicotinic acid from half sugar.

In 1913, American scientists McCollum and Davis and Mendel discovered that vitamin A deficiency caused night sickness.

In 1914, American scientist Kendall confirmed the relationship between iodine and thyroid function, and won the Nobel Prize.

In 1918, American scientists Osbome and Mendel confirmed the need for sodium.

In 1924, American scientists Thomas and Mitchell proposed a method of evaluating protein quality based on biological value.

In 1926 Dutch scientists Jansen and Donath isolated vitamins against beriberi.

In 1926, French scientist LeRoy proved that magnesium is an essential nutrient.

In 1927, American scientist Summer proved that an enzyme is a protein.

In 1928, American scientist Hart and colleagues found that copper and iron were necessary for the synthesis of hemoglobin.

In 1929, American scientists Burr GM and Burr MM discovered the essential fatty acid linoleic acid.

In 1930, British scientist Moore confirmed -carotene as a vitamin A precursor.

In 1931, the University of Wisconsin research team proved that manganese is one of the essential trace elements.

In 1932, American scientists King and Waugh isolated vitamin C from lemon juice.

The overview of nutrition in various countries is extracted from the research papers of experts and scholars on the development of nutrition in various countries. Due to the limitation of space, only the abstract content is extracted, and interested parties can directly read the full text of the paper. The United States is the representative of nutrition in the field of decomposition, China is the representative of holistic nutrition, and Japan has both characteristics. Japan is not a developed country in nutrition. A 2004 survey found that Japan has no system in clinical nutrition and the nutritional status of its citizens is a cause for concern. These are issues that deserve attention.

The initial development laid the foundation for contemporary nutrition. Through nearly one hundred years of development history, we can see a complete picture of American nutrition. Its development context is an overview of Descartes's decomposition of thoughts, the rise of natural science thoughts, and the simultaneous horizontal development in modern times. Part of it began to repeat the history of classical nutrition. Through the summary of modern experiments, it confirmed the guiding significance of classical nutrition.

In terms of data, American nutrition has undergone mechanized and instrumental evolution, and tried to take the development of nutrients as the ultimate goal, but it ended in failure, and entered a stage of overall and systematic research, in order to find a life code through systematic research ideas Information to guide and reflect on the right and wrong experiences of nutrition in past history. Represented by the new Pyramid diet structure in the United States, the model of the U.S. Pyramid has returned to the essence of classical nutrition, which is consistent with the compound thought advocated by the Chinese "The Yellow Emperor's Canon". The concept of "five animals for the benefit and five dishes for the charge" is considered by the academic circles to be a trend triggered by the return to natural trends.

Japanese Nutrition

The development of nutrition science in Japan originated from the guidance of dietary health. With the support of national laws and related regulations, Japan has gone through the stages of dietary guidance, health legislation, clinical nutrition, establishment of a nutritionist system, and popularization of nutrition courses. Compared with other countries, Japan has the characteristics of continuity and strong execution, and the country is equipped with specialized functional departments for health intervention. Japan's diet pattern has quietly changed, moving towards high protein and high fat directions, and has been separated from the dietary field described in history. Contemporary Japanese nutrition agencies are taking corrective action. This article is of significance for understanding and studying the development of contemporary nutrition.

Chinese classical nutrition

Chinese classical nutrition has a long history and has a history of 7000 years. Classical nutrition describes in detail the exploration and discovery of the laws of man and nature by nutritional masters and health scholars of various generations, and has formed a variety of nutrition books. The core of the thought of classical nutrition is holistic view, which reflects

In order to understand the harmonious relationship between man and nature, the regular elaboration in the field of diet and health care has influenced so far. Classical nutrition view of diet, nutrition balance, view of natural ecology, view of harmony between man and nature, clinical principles of nutrition, etc., have far-reaching significance for the development of contemporary nutrition, and have guiding value for guiding the development of modern nutrition. The future direction of classical nutrition will explore the essential value of nutrition for human beings, and it will have a significant impact.

The origin of classical nutrition in China is earlier, and the specific time cannot be examined. "The Yellow Emperor's Canon" belongs to the earliest monograph on nutrition and medical theory in China, dating back over 2000 years. However, the book still uses the phrase "ancient man" in many places. Then, the authors of 2000 years ago believed that the earliest time could not be known if there were various experiences passed down by more ancient people. It is generally believed that Chinese civilization can be traced back to the "era of knotting" and still has a history of more than 7,000 years.

After a long history of inheritance and accumulation, the ancient Chinese have created numerous nutritional theories and formed a complete system. The complexity of this system is beyond the scope of experience accumulated by contemporary people, and cannot be thoroughly studied one by one. Under such a situation, scholars and experts cannot systematically grasp such a vast and complex engineering system. Most experts choose to study a monograph or a theory. For example, if you choose to specialize in books such as The Yellow Emperor's Internal Classics or Treatise on Febrile Diseases, or to study the theory of yin and yang, the relationship between the five elements, and the four flavors and five flavors, or to study the clues or ages of each nutrient to form a work, you cannot exhaust the essence and secret.
