Abstract
BACKGROUND: The prevalence of type 2 diabetes (T2D) has increased substantially in the past few decades throughout the world. In India, the epidemic of diabetes continues to increase irrespective of area, status, and age. Despite various scientific societies involved in the treatment of diabetes, still, the burden of diabetes keeps growing. AIMS: The aim of this work is to explore the Ayurvedic concept of a personalized diet to modulate the gut microbiota for the treatment of T2D. MATERIAL AND METHODS: A thorough study of literature from online scientific databases including Web of Science, PubMed, Scopus, and Google Scholar as well as from classical texts of Ayurveda was done. A careful compilation was done to extract the valuable output of the personalized diet to modulate the gut microbiota. RESULTS: There are various diets used to control blood glucose levels, and their effects are also being studied on the transcriptome or epigenome despite 99.9% genomic similarity among human beings. However, microbiomes have only 10% similarity. Ayurvedic diet is given on the basis of Prakriti (body constitution), therefore, it is also called personalized diet. CONCLUSION: The diets prescribed for T2D in Ayurveda are high in fibers, polyphenols, and complex carbohydrates which enrich butyrate-producing bacteria and decrease lipopolysaccharide-producing bacteria. Hence, there is a need to have a personalized diet to manage the glucose level by enriching beneficial gut microbiota. The approach of a personalized diet associated with gut microbiota can be helpful in maintaining blood sugar in T2D patients.
