Two individuals may share the same meal yet experience entirely different health outcomes—why? This book explores the hidden driver behind that difference: the human genome, and how it interacts with nutrients, lifestyle, and environment to shape metabolism, disease risk, and lifelong wellbeing.
Textbook of Nutrigenetics & Nutrigenomics moves beyond terminology-heavy learning, presenting genetics and nutrition as a narrative rather than a syllabus. From Mendel’s pea plants to SNP science, epigenetics, and personalized nutrition, each chapter invites readers to experience the science rather than memorize it.
The book raises key questions: How did ideas from Darwin, Lamarck, and Mendel evolve into precision nutrition? What makes DNA a dynamic blueprint that can be influenced by lifestyle? Why do identical genes behave differently across individuals? How do nutrients regulate gene expression? How do SNPs shape everyday health choices? And is obesity merely about calories—or a complex interaction of biology and genetics?
What sets this book apart
Story-driven explanations instead of dense technical blocks
Powerful analogies that make complex concepts intuitive
Real-life case scenarios linking evolution to clinical practice
A seamless bridge from genetics to epigenetics, obesity, metabolic traits, and applied nutrition
Ideal for students who find genetics intimidating—and end up fascinated.
Endorsement
“A rare textbook that teaches the mind and engages the imagination. Perfect for universities transitioning toward precision nutrition.” — Dr. Bhawna Sati, Clinical Nutritionist, Head of Nutrigenomics, NuGenomics, India

Dr. Shanthi Lakshmi Duraimani
Dr. Shanthi Lakshmi is a molecular geneticist and nutrigenetics specialist focused on how lifestyle influences gene expression and long-term health. Her journey began during her PhD in Lifestyle Genetics, where she studied how diet, meditation, and nutrition modulate telomerase gene expression, linking lifestyle with aging and cellular health.
She has worked across behavioral science, molecular biology, and health technology, shaping her understanding of human behavior, systems biology, and healthcare innovation, and guiding her shift toward nutrigenetics.
As Chief Scientific Officer at NuGenomics, she led R&D, product design, coaching frameworks, and operations, trained 100+ nutritionists, and guided 3,000+ individuals using genetic insights for metabolic, cognitive, and overall wellness.
Currently, as Director of R&D at ExtendingMe, she develops and validates nutrigenetic and epigenetic panels, integrating polygenic risk scoring with actionable lifestyle strategies. Her work focuses on translating complex genetics into clinically relevant, personalized solutions.
