This book explores what is needed to bring nutrigenomics, nutrigenetics, and their associated technologies to market in a truly impactful way. Exploring nutrigenomic (effects of diet on gene expression) and nutrigenetic (matching diet to genotype) approaches, it covers a wide range of issues, from scientific to ethical, consumer-driven, and public health aspects. Topics include food-gene interactions, the modulation of disease risk, regulatory challenges, genetic testing for consumers, data mining, and the role of science and health professionals in the commercialization of nutrigenomics and nutrigenetics.
