Dietary influence on gut microbiota and epigenetic factors in metabolic disorders: exploring mechanisms and therapeutic strategies

Metabolic disorders, with their far-reaching impact on public health, stand as prominent global concerns. Recent studies indicate that the intricate connection between the elements in our diet, the composition of the gut microbiome, and epigenetic factors play a vital function in the initiation and advancement of chronic complications. A vast population of 100 trillion beneficial bacteria are present in the gastrointestinal canal of humans, causing disturbances in the intestinal microbiota and dysbiosis, which is further responsible for various health conditions. The gut microbiome has been increasingly recognized for its potential influence on epigenetic modifications. A fundamental pathway combining multiple elements in modifying genetics involves metabolic production, a crucial factor and allosteric controller influencing epigenetic phenomena. Epigenetic factors, including DNA methylation, histone modifications, and non-coding RNAs, can significantly impact gene expression related to metabolic pathways. These alterations play an important factor in overall well-being and susceptibility to diseases. The chapter delves into the intricate mechanisms through which dietary choices impact the gut microbiota, microbial metabolism, and the subsequent effects on host epigenetic regulation. It highlights the key players in this complex web of influence, including the immune system and signaling molecules. In conclusion, this chapter underscores the pivotal contribution of dietary intake in forming the intestinal microflora and epigenetic landscape, thereby impacting the development and progression of metabolic disorders. Understanding these complex relationships opens the door to novel therapeutic strategies and preventive approaches considering genetic and environmental influences.
