Yu Jianchun, director of basic surgery, Peking Union Medical College Hospital, said that although both of them seem to be related to the word "nutrition", there is a strict distinction between this special medical purpose formula food and health care products. Yu Jianchun says there are some nutrients in the health care product, but it has no medical proof and lack of medical evidence. The enteral nutrition preparation currently used in clinic has sufficient theoretical basis and clinical evidence. It must be guided and chosen by different doctors or dietitians under different guidance. "Simply speaking, there are no indicators in clinical practice to verify whether taking health care products has a role, but for enteral nutrition preparations, clinical evidence can be produced, such as detects increased or decreased protein after taking."

From the supply of different groups, enteral nutrition is a kind of special food produced not for the ordinary people, but in order to meet the nutritional needs of daily feeding restriction, digestion and absorption of disorders or metabolic disorders and other groups, or in order to meet the patients on the part of nutrients or dietary special needs. Clinicians believe that the way enteral nutrition is easier to be absorbed by the body, and to protect the intestine.

Since this special product does not belong to health care products, it is also for the patient, and there is a consumer question, will it be a drug? Yu Jianchun also gave a negative answer to this. In terms of the function of the product, she said, special medical formula food is a kind of product between common food and medicine. According to the form, composition and clinical use of the product, it is believed that it is more appropriate to incorporate it into the food management. Moreover, the special medical use formula food is a special food, it doesn't have the therapeutic effect for some kind of disease, but to improve the nutritional status of the patient, improve the overall health of the patient, and provide a good foundation for the treatment and recovery of the disease.

Although it is not a drug, it is not as dangerous as the drug is used in the wrong way, but it also affects the use of the patient. So this kind of food is not chosen by the patient, but under the guidance of a doctor or dietitian, so only the hospital has such special foods. " Yu Jianchun reminding. The role of nutrition in medical treatment is becoming more and more important. Michel, chairman of the International Association for the medical nutrition and public welfare, said in public this year that we need to develop targeted nutritional solutions to meet individual needs today and in the future. And "enteral nutrition" is aimed at different cases, and therefore has a "personality".
