Abstract

Due to its grave pathological role of obesity, comprehensive research is being continued to find out the causative factors involved in it. Recent advances in this field are increasingly recognized that there is a connection between diet, gut microbiota, intestinal barrier function and the low-grade inflammation that characterize the progression from obesity to metabolic disturbances, making dietary strategies to modulate the intestinal environment is important. In this context, the ability of some Gram-positive anaerobic bacteria to produce the shortchain fatty acid butyrate is impressive. A lower abundance of butyrate-producing bacteria has been associated with metabolic risk in humans. Recent studies suggest that butyrate might have been linked with metabolic risk in humans, and recommend that butyrate might have an anti-inflammatory mediator in metabolic diseases, and the potential of butyrate can alleviate obesity-related metabolic complications, possibly due to its ability to enhance the intestinal barrier function. Endogenous butyrate synthesis, delivery, and absorption by colonocytes have been well studied. Butyrate exerts its function by serving as a histone deacetylase (HDAC) inhibitor or signaling through several G Protein-Coupled Receptors (GPCRs). Latterly butyrate has gained selective attention for its favorable effects on intestinal homeostasis and energy metabolism. With anti-inflammatory properties, butyrate improves intestinal barrier function and mucosal immunity. Growing proof has highlighted the influence of butyrate on obesity. In this review the current knowledge on the features of butyrate, especially its potential effects and mechanisms involved in intestinal health and obesity. Here we review and discuss the potentials of butyrate as an anti-inflammatory mediator in obesity and the potential for dietary interventions increasing intestinal availability of butyrate.
