Nutrigenomics is an emerging science that employs the tools of food and nutritional sciences, biochemistry and molecular biology, physiology, genomics, epigenomics, proteomics, transcriptomics, and metabolomics to assess the interaction between nutrients and genes, in relation to how it can be applied for the management and treatment of diseases. Role of Nutrigenomics in Modern-day Healthcare and Drug Discovery presents novel insight into how these tools can be applied in the study of nutrient-gene interaction for the management of certain disease conditions without using synthetic drugs or other treatments that come with side effects. Divided into three parts, part I presents chapters that give background information of the subject while laying a framework for other chapters to follow. Part II presents chapters that discuss the role of nutrigenomics in healthcare, while part III presents chapters that discuss the role of nutrigenomics in modern day drug discovery. Written by a global team of experts from key institutions around the world, this book is useful for drug developers, medicinal chemists, public health scientists, molecular biologists, biochemists, toxicologists, and food scientists.
