Abstract: While research on the functional effects of probiotics has been extended to include their roles in prevention and treatment of immune, metabolic and neuroemotional disorders, a systematic review of the numerous studies in this regard is still lacking in the literature. In this paper, we summarize recent animal and clinical studies on the two probiotics, Lactobacillus and Bifidobacterium and recent studies on their mechanism of action. A number of studies demonstrate that the application of probiotics as a functional food ingredient will help further improve people’s health and living standard. The mechanism of action of probiotics on human diseases and disorders especially the body’s responses to different probiotics, which allows the development of therapeutic strains for clinical applications, will represent an important direction of research in the future.
