摘　　要：The virome is the most abundant and highly variable microbial consortium in the gut.Because of difficulties in isolating and culturing gut viruses and the lack of reference genomes,the virome has remained a rela-tively elusive aspect of the human microbiome.In recent years,studies on the virome have accumulated growing evidence showing that the virome is diet-modulated and widely involved in regulating health.Here,we review the responses of the gut virome to dietary intake and the potential health implications,presenting changes in the gut viral community and preferences of viral members to particular diets.We further discuss how viral-bacterial interactions and phage lifestyle shifts shape the gut microbiota.We also discuss the specific functions conferred by diet on the gut virome and bacterial community in the context of horizontal gene transfer,as well as the import of new viral members along with the diet.Collating these studies will expand our understanding of the dietary regulation of the gut virome and inspire dietary in-terventions and health maintenance strategies targeting the gut microbiota.
