Abstract Many studies have reported that dietary fibers play a crucial role in promoting intestinal health of the host, since it strengthens functions of epithelial barrier and meanwhile maintains intestinal homeostasis of the host by modulating gut microbiota and short‐chain fatty acid (SCFA) production. Pig is a good animal model to study effects of dietary fiber on gut health and microbial community. This review has summarized the relevant knowledge available based on roles of various dietary fibers in gut health and energy metabolism of pigs and humans. Evidences summarized in our review indicated that modulating intestinal microbial composition and SCFA production by consuming specific dietary fibers properly could be conducive to health improvement and disease prevention of the host. However, types of dietary fiber from edible foods exert divergent impacts on gut health, energy metabolism, microbial composition, and SCFA production. Therefore, more attention should be focused on different responses of various dietary fibers intake on host metabolism and health.
