Nutrigenomics & Genetic Personalization
Genes, SNPs & the Truth About "Eating for Your DNA"
About this volume
Nutrigenomics & Genetic Personalization is Book H2 of The Performance & Human Physiology Encyclopedia — a 93-volume, university-level library on what supplements and nutritional levers actually move — and what they don't. It is written for athletes, coaches and clinicians navigating the supplement aisle: deep enough that a professional already trained in the field keeps learning, structured clearly enough that a motivated reader can follow every step.
How this book is written
- University level, without dilution. Exact scientific terminology, defined at first use — mechanisms, not just conclusions.
- Myths tested against the evidence. Where a popular claim does not survive the evidence, the book says so — and shows why.
- References at the end of every chapter. Sources cited in APA 7 style, plus a master bibliography.
For general information and education only; not medical advice. Consult a qualified health professional before acting on its content.
Read an excerpt
From Chapter 1 — Nutrigenomics & "Eat for Your Genes": Promise, Hype & How to Judge It
"Spit in a tube, the ad says, and learn the diet you were born to eat. It's an irresistible promise — nutrition tailored to your unique DNA — and it sits on top of a real and fascinating science. But between the laboratory finding that a gene variant nudges how you handle caffeine and the glossy report telling you to avoid carbs 'because of your genotype' lies a vast gap. This book lives in that gap: honest about what your genes can tell you about food, and honest about how much they can't."
"Eat for your genes" is a booming wellness category — DNA-diet kits, "genetic nutrition" reports, and bestselling books. Underneath is genuine science (genes do affect nutrition, and vice versa), but the consumer products vastly overpromise what they can personalize. This opening chapter defines the field, draws the science-vs-marketing line, and sets the honest filter for the rest of the book (which completes Collection H).
