THE NUTRIENT-GENE-HORMONE AXIS

Abstract

The interaction between Nutrients, Genes and Hormones that significantly influence human physiology and metabolic homeostasis. Emerging evidence from nutrigenomics and nutrigenetics studies unveils the ways that nutrients modulate various downstream hormonal signaling, gene expression and epigenetic profile which then may impact on metabolic outcomes and potential disease risk. Recent researches further declares that every smaller change in dietary habits can trigger substantial shifts in metabolism pathways during interaction with specific genetic variants or mechanism of hormonal regulation. Some nutrient-gene relationships illustrate how genetic variation can alter the efficacy of nutrients, modify enzyme kinetics and impact disease susceptibility. The hormonal mediators like insulin, leptin, cortisol, thyroid hormones and sex-steroid hormones act as essential connectors which helps to integrate nutrient availability during molecular responses across tissues. These hormone functioning pathways helps in to coordinate the balance of energy, regulation of appetite, controls the inflammation, and lipid–glucose homeostasis, all of which are strongly bounded by nutrient intake and genetic predisposition. Individual responses to nutrients vary person to person, emphasizing the importance of understanding personalized metabolic signatures. Such personalized strategies aim to increase nutrient efficiency, lowering the disease risk and improve long-term metabolic resilience. There is still research required between mechanistic findings and therapeutic guidance and further long term, well-characterized controlled studies. Current studies are still evolving and require validation through multi-omic approaches that focuses genomics, metabolomics, proteomics or endocrine profiling. This article describes the present studies on nutrient-gene-hormone axis along with key molecular mechanisms, clinical consequences and possible future approaches for precision nutrition. It further shows how advancements in technologies and biological databases may increases the transition from generalized nutritional advice toward highly individualized interventions.
