In this module, you will explore the structure and function of the human genome and its role in precision nutrition. You will learn about DNA organization, including nucleotides, chromosomes, and chromatin, as well as key concepts such as the central dogma of biology—transcription, translation, and protein synthesis. The module also introduces genetic variation, including single nucleotide variants (SNVs), and how differences in genotype influence phenotype and dietary responses. By the end, you will understand how genomic structure and gene function inform personalized nutrition and health outcomes.

In this module, you will explore how genetic variation and epigenetic processes influence health and personalized nutrition. You will learn about different types of genetic variants—such as SNVs, INDELs, and larger structural changes—and how they are identified, described, and applied in areas like nutritional genomics and direct-to-consumer testing. The module also introduces epigenetics, focusing on how gene expression is regulated through mechanisms like DNA methylation and histone modification, and how factors such as diet, toxins, and stress can shape these changes. Drawing on key animal and human studies, you will examine how environmental influences can have lasting and even transgenerational effects. By the end, you will understand how genetic and epigenetic factors interact to inform precision nutrition and individualized health strategies.

In this module, you will explore the principles of precision nutrition and how data—from diet to genetics—supports personalized health strategies. You will examine omega-3 fatty acids as a key example, including their health benefits, dietary sources, and variation across populations. The module also covers diet–gene interactions and how genetic differences influence nutrient metabolism, along with the importance of tailoring nutrition to diverse populations. Finally, you will learn how to apply these concepts by designing personalized nutrition plans and addressing real-world challenges in implementation.

In this final module, you will synthesize the key concepts from the course, integrating knowledge of diet, genetics, epigenetics, environmental exposures, and population diversity to evaluate precision nutrition approaches. Through a comprehensive final exam and applied assignment, you will demonstrate your understanding of how genetic variation, gene expression, and dietary factors interact to influence health and disease. This module provides an opportunity to apply theory to practice by critically analyzing evidence and developing personalized or population-based nutrition strategies grounded in precision nutrition principles.
