Diversity in Healthy Indian Gut Microbiome Metagenomics of the Human Intestinal Tract (MetaHIT) Pitta- Kapha, and Vata-Pitta-Kapha Prakriti types. Amongst the consortium. These studies have provided insights into the seven constitution types, Vata, Pitta, and Kapha are the three composition of microbial community at various anatomical sites phenotypic extremes with contrasting disease susceptibilities. (Human Microbiome Project Consortium, 2012; Parfrey and Phenotypic assessment of Prakriti is carried out on the basis Knight, 2012). The human microbiota has co-evolved closely of examination of approximately 150 features comprising with its host (Yatsunenko et al., 2012; Moeller et al., 2016) and of anatomical, physiological, activity related attributes, and is modulated by intrinsic and environmental factors. Recent psychological parameters. For example, individuals of Pitta studies have indicated that health and predisposition to various Prakriti would have better digestion and metabolic capacity non-infectious diseases of humans are also determined by the whereas Kapha would have less and Vata with an irregular genes coded by resident microbiome (Albenberg et al., 2012; Cho or unpredictable pattern. Recently, we have also been able and Blaser, 2012; Gordon et al., 2012; Zhang et al., 2015). It is to develop predictive models for Prakriti that recapitulate appreciated now that an understanding of human physiology the Ayurveda constitution types through phenotypic traits of is incomplete without the knowledge of the metagenome. individuals (Prasher et al., 2008, 2016). Contemporary approaches have focused on investigating the Many of the phenotypic attributes that are being associated microbial assemblage of the transient states observed over the with microbiome difference also differ between the constitution course of specific diseases. However, the challenge is to elucidate types. This includes desire and suitability for different diets, whether the association between microbial community changes metabolic and digestive patterns, weight gain tendencies, gut and pathology is causal in nature (Clemente et al., 2012; Haiser motility and excretory patterns (Prasher et al., 2008, 2016). and Turnbaugh, 2012). Integrative analysis of human genome, Besides, certain therapeutic modalities unique to Ayurveda physiology and microbiome will enable better understanding as that are aimed at maintenance of health and homeostasis to whether latter is involved in health and disease. However, lays emphasis on restoration of healthy flora (Prasher et al., there are variables contributed by human host as well as 2016, 2017). Earlier, we and other groups have shown that the microbiome, which could confound the observations. For healthy individuals of extreme Prakriti types, Vata, Pitta, and example, the ethnicity and genetic background, age of the Kapha comprise 8–10% of a population and exhibit genome individual, dietary and lifestyle habits; all of which have been wide differences amongst constitution types, albeit from a known to affect the human physiome and shape the microbiome genetically homogeneous background (Prasher et al., 2008; (Fortenberry, 2013; Chong et al., 2015). Studies to identify Aggarwal et al., 2010; Rotti et al., 2014; Govindaraj et al., association between microbial community structure based on 2015). These sub-types have underlying differences in genes that ethnicity, diet, gender in healthy individuals, have met with modulate pathways for apoptosis, metabolism, hypoxia response, limited success (Chong et al., 2015; Bhute et al., 2016).

These differences can contribute of definitive patterns has been ascribed to genetic drift as well to inter-individual variability in adaptation to high altitudes, as population admixture. Therefore, it is a challenge to develop susceptibility to high altitude pulmonary edema or thrombotic a population based catalog of human microbiome markers outcomes in hypoxia (Prasher et al., 2008; Aggarwal et al., 2010, for predicting disease predisposition especially for a diverse 2015). Considering the significance of human microbiome in Indian population.
