The Role of Diet and Gut Microbiome in Multiple Sclerosis.

Multiple sclerosis (MS) is a chronic demyelinating condition of the central nervous system (CNS) characterized by immune-mediated damage to the myelin sheath of nerve cells. Genetic and environmental factors are believed to play a significant role. Unfortunately, the knowledge of therapeutic modalities in MS remains very limited, necessitating the need for novel therapeutic strategies. In the previous decade, there has been an influx of studies on the gut microbiome and its link to various neurological conditions, including MS. Various diets may have favorable effects on the gut microflora and may significantly alter the progression and outcomes of MS. Thus, identifying the merits of various diets and modulating them according to the specific nutritional requirements of MS patients can go a long way toward slowing the progression of the disease. Nutritional interventions and the use of the gut microbiome as diagnostic and therapeutic modalities open a host of new possibilities regarding the disease. In this review, we investigate the role of diet and the gut microbiome in the progression of MS. The functions of the gut-brain axis, antioxidants, vitamins, obesity, and various diets are also covered in this article.
