2. Special diet food is the abbreviation of Foods for special dietary uses, and its English name is foods for special diet uses. The General Rules for the Labeling of Prepackaged foods for special dietary uses (GB 13432-24), which was implemented in China on October 1, 25, defines special dietary products as "food specially processed according to a special formula to meet the physiological needs of some special people or the nutritional needs of some patients with diseases." Special dietary food is a kind of food that has been issued by the state in addition to the management standards of ordinary food, health food and medicine. The difference between special dietary products and ordinary foods is that the purpose of eating special dietary products is to strengthen nutrition for special people, reduce metabolic burden, regulate physiological functions, and reduce side effects of drugs. Ordinary food only provides basic nutrients needed by the human body to meet normal physiological needs. Special dietary products have special nutritional orientation, providing rich nutritional components for special people that are difficult to ingest from daily ordinary meals, while ordinary foods are not specifically targeted for special people. Therefore, special diet products need to adopt special formula and technology to ensure the pertinence of their components and the directionality of their functions. The difference between special diet food and health food Health food can provide some health care functions for some physiological functions of the body, and generally does not aim at providing nutrition, especially it can not meet the targeted nutritional supplement at a specific physiological stage, so it is not suitable for long-term use as ordinary food. Special dietary products have comprehensive nutritional value for special people and can be eaten as daily food for a long time. The difference between special dietary products and drugs: special dietary products provide special nutrients for special people and minimize the metabolic burden, but unlike drugs, special dietary products cannot be directly used to treat diseases. Significance of developing special dietary products The essence of nutrition is balanced nutrition. It is difficult for some special people to achieve this goal through ordinary food, so they must resort to special dietary products. In fact, every specific group of people should and can have corresponding special meals. Nutrition industry is both a traditional industry and a sunrise industry. From a macro point of view, the nutrition industry has a wide range of products, including nutrients, supplements, functional foods, fortified foods, dietary supplements, etc., and with the growth of demand, new varieties will continue to appear, such as emerging special dietary products. Some experts say that there are no grain stores in developed countries, and only food stores sell standardized processed agricultural products. This is not only the requirement of agricultural industrialization, but also the guarantee of food safety. Therefore, with the continuous renewal of ideas, new products will appear continuously, and the next five years will be a period of great development of nutritional products and special dietary products. From the microscopic point of view, while the varieties of special dietary products are expanding, the functions of special dietary products will be refined. Forms of Special Dietary Products There are many forms of special dietary products due to the different nature of products and the diversification of consumer demand. There are ready-to-eat and cooked foods and semi-finished products; There are solid and fluid. Types of special foods Special foods mainly include foods under special physiological conditions (different physiological stages, different physiological conditions, various diseases, etc.), special environmental conditions (high temperature, low temperature, diving high pressure, high altitude low pressure, high radiation, etc.) and special working conditions (heavy physical labor, night work, welding work, etc.). The development of special dietary products The Chinese nation has a long and rich diet culture, and it has long been recognized that people with different physiological conditions should not have the same diet. Traditional Chinese medicine (TCM) emphasizes the "appropriateness" and "taboo" of diet while differentiating symptoms and treating diseases, summarizes a variety of secret recipes of medicinal diet, finds a variety of "hair products", and puts forward the concept of homology of medicine and food and the concept that medicine tonic is not as good as food tonic. Food supplement and dietotherapy, which take food as medicine and substitute food for medicine, are quite common among the people. In recent years, China's Ministry of Health has published three catalogues of both medicines and foods, as well as a catalogue of new food resources as general food management. These substances, both food and medicine, are safe for human body and have certain functions.
