Mass media is playing an increasingly important role in modern society. People can obtain relevant information through mass media, and can also provide a basis for people's behavioral decisions. All aspects of people's lives are affected by the mass media. In terms of obtaining nutrition information, people are gradually turning to online channels. Therefore, the influence of nutrition information disseminators in the mass media cannot be ignored. The main research is on the influence of nutrition information disseminators on the mass media and the empirical relationship network. Through sampling methods, 49% of the 50 medical and health information disseminated by the mass media are related to diet and nutrition. However, only 20% of the 50 pieces of information that ten experts agreed with the information disseminators, while the approval rate on diet and nutrition was 0 out of 38. The results show that the government and media users have a great influence on the users outside the nutritionist network. However, in the network, some academics, nutritionists and media users are the main communicators. They have close ties. Media users should disseminate high-quality nutritional information to the public through researchers, hospitals and nutritionists. And promote the second dissemination of government users.
