In order to explore and analyze the research status， hot spots and trends in the field of anti food allergy at home and abroad from 2010 to 2019， based on the bibliometric perspective， the Citespace software system was used to visually analyze 748 relevant literatures in the field of anti food allergy retrieved from the web of science database. The results showed that， from 2010 to 2019， the number of papers on anti food allergy related topics showed an overall growth trend， with a steady growth rate；at present， the hot spots in the field of anti food allergy mainly focused on the in-depth exploration of food allergy mechanism and the research of new prevention and treatment methods， and the related mechanism research is gradually deepening， which is roughly manifested in the changes in the level of immune related cytokines and immunity. The research of new therapy includes the development and property modification of natural active substances， non-specific treatment methods such as probiotics， oral immune tolerance and subcutaneous injection immune tolerance. Based on the objective bibliometric analysis and Citespace， this paper analyzes the main contents and hot research directions in the field of anti food allergy， which is helpful for scholars in related fields to deepen the overall understanding of this field.
