Nutritional Genomics and Nutrigenomics: Personalized Nutrition for Disease Prevention and Health Optimization

Abstract

Abstract

Nutritional genomics, encompassing nutrigenomics and nutrigenetics, represents a transformative intersection of nutrition science and genomics. This field examines how individual genetic variations influence the body's response to nutrients and how specific dietary patterns can modulate gene expression. By leveraging genomic data, researchers and clinicians aim to develop personalized nutritional interventions that promote optimal health and mitigate disease risks. Nutrigenomics studies how nutrients affect gene activity, while nutrigenetics focuses on how genetic differences alter the metabolism and effects of nutrients. This paper presents an in-depth exploration of the key concepts, molecular mechanisms, research methodologies, clinical applications, ethical considerations, and future directions in nutritional genomics and nutrigenomics. The integration of advanced omics technologies, bioinformatics, and precision nutrition holds promise in revolutionizing public health and preventive medicine.
