Prakriti phenotypes as a stratifier of gut microbiome: A new frontier in personalized medicine?

ABSTRACT

Ayurveda has a rich history and its significance woven deeply in the Indian culture. The concept of prakriti (a person’s “nature” or constitutional type determined by the proportion of three doshas, namely - vata, pitta and kapha) in Ayurveda is deeply rooted in personalized health management. While the attributes of prakriti has been established to have a genomic basis, there is dearth of elaborate evidences linking prakriti with manifestation of diseases. Next generation sequencing studies have provided a causal link between variation in the gut microbiome and its effect on an individual’s fitness. Separately, reports have identified gut microbial patterns associated with several host variables such as geography, age, diet and extreme prakriti phenotypes. Recently, few reports have identified a “core gut microbiome” consisting of Bacteroides, Faecalibacterium, Prevotella and Ruminococcus prevalent across the Indian population; however, a few bacterial genera were specifically enriched in certain prakritis. Hence, in this review we aim to analyse the role of prakriti variations on dysbiosis of the gut microbiome and concomitantly its effect on human health. We suggest that prakriti phenotyping can function as a potential stratifier of the gut microbiome in a given population and may provide evidence for the conceptual framework of personalized medicine in Ayurvedic system of medicine.
