The emergence of dietitian profession is to meet the needs of social health. Nutritionist is a comprehensive profession, which combines the characteristics of chefs, health professionals, medical practitioners, practitioners of Chinese medicine, psychologists, marketers and administrators. They are not only experts in food, but also experts in nutrition detection, nutrition fortification, nutrition evaluation and other fields to help people get healthy. The professional requirement of dietitians is to focus on health professional services.
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 warn at any time 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.
