Traditional nutrition science tends to generalize nutrient responses, overlooking some individual differences. Nutritional genomics, which explores the connection between nutrition, genetics, and biology, is emerging as a field that supports the development of personalized dietary recommendations. Genotype-specific nutrition guidance can further optimize individual health. Advances in this area have the potential to enhance both public and professional understanding of nutrition, leading to the creation of customized, biomarker-driven interventions for various health issues. Nutrigenetics and nutrigenomics are increasingly important in clinical research and practice for disease prevention, health promotion, and overall wellness. This review delves into the development and interrelationship of these fields, emphasizing their growing role in modern healthcare. It highlights how genetic variations impact individuals' responses to nutrients and examines the implications for managing and preventing non-communicable diseases such as obesity, type 2 diabetes, cancer, and cardiovascular disease. The review concludes by addressing the challenges of applying nutrigenetics and nutrigenomics in clinical settings, particularly in precision healthcare and personalized nutrition. Key challenges include translating genetic insights into actionable dietary recommendations and ensuring individualized nutrition interventions are accessible and effective across diverse populations.
