Ayurnutrigenomics: A step towards personalized nutrition

 Dr Shifa


                     Nutrigenomics establish the influence of nutrients and other bioactive food components on gene expression and gene regulation. Recent availability of human genome sequence and the cataloguing of human genetic variations, can identify specific polymorphisms linked to altered risk of disease or sensitivity to diet. Information on the genetic order of polymorphic markers will provide powerful molecular tools to decipher the role of nutrition in human health and disease and helps to define optimal diets. Nutrigenomics provide specific dietary recommendations on the basis of genotype of individuals.

Ayurnutrigenomics is the systematic integration of nutritional practices according to Ayurveda in relation to the Prakriti of an individual, which amalgamates information from genomics, proteomics, and metabolomics for the advancement of personalized nutrigenomic dietetics

Prakriti represents the basic principles of Ayurveda having great impact on predictive medicine and it is the corollary of comparative proportion of tridoshas. In Ayurveda, selection ofsuitable dietary, therapeutic, and lifestyle regime is made on the basis of assessment of Prakriti. Prakriti is not only genetically determined (shukra sonita) but also influenced by environmental factors (maha bhuta vikara) like maternal diet and lifestyle (matura ahara vihara) and age of the parents (kala garbhasaya)

Prakriti and genome

The identification of genomic link to the theory of prakriti led to a search for possible classification of people on their prakriti based on their genetic makeup. A significant correlation between various alleles of HLA genotype and prakriti providing preliminary experimental support for the concept of association between HLA polymorphism and individual prakriti types. Association between prakriti and gene related to drug metabolism such asCYP2C19 have been drown out, where the genotype related to extensive metabolizer genotype was associated with pitta prakriti ,while the poor metabolizer genotype was highest in kapha prakriti . On searching for links of prakriti and genotypes is the need of the hour to bridge the gap between Ayurveda and current sciences with the development of common vocabulary. Assessment of prakriti through genotype mapping is a method of objective assessment of prakriti

Prakriti and Personalized nutrition

                       Prakriti can be considered as phenotypes that have distinct link with particular genotype. Through prakriti genome correlation studies possibility of identifying specific genotype linked to a particular prakriti is approaching. Thus it can be anticipated in near future genotype ascertainment in new born itself can be used as a predictive marker for prakriti

                          Detection of prakriti at the time of birth have far reaching implications. Knowing the prakriti of newborne can lead to adption of suitable dietary practices

from early childhood onwards  which will result in prevention of diet related chronic disease. This is the way in which prakriti based diet plays its action

If a specific genotype is identified related to a particular type of prakriti, the concept of gene specific diet can be taken to authenticate diet according to prakriti.
