Engineered Probiotic and Prebiotic Nutraceutical Supplementations in Combating Non-communicable Disorders: A Review.

Nutritional supplementations are a form of nutrition sources that may help in improving the health complexities of a person throughout his or her life span. Being also categorized as food supplementations, nutraceuticals are products that are extracted from edible sources with medical benefits as well as primary nutritional values. Nutraceuticals can be considered as functional foods. There are evidences that nutraceutical supplementations can alter the commensal gut microbiota and help to prevent or fight against chronic non-communicable degenerative diseases in adults, including neurological disorders (Autism Spectrum Disorder [ASD], Parkinson's disease [PD], Multiple sclerosis [MS]) and metabolic disorders (Type-II diabetes, obesity and non-alcoholic fatty liver disease). They can even lessen the complexities of preterm babies like extra-uterine growth restriction, necrotizing enterocolitis, infant eczema and allergy (during pregnancy) as well as bronchopulmonary dysplasia. Molecular perception of inflammatory and apoptotic modulators regulating the pathogenesis of these health risks, their control and management by probiotics and prebiotics could further emphasize the scientific overview of their utility. In this study, the pivotal role of nutraceutical supplementations in regulating or modulating molecular pathways in the above non-communicable diseases is briefly described. This work also gives an overall introduction of the sophisticated genome-editing techniques and advanced delivery systems in therapeutic activities applicable under these health risks.
