What is nutrigenomics?

Nutrigenomics examines the interactions between nutrition and genetics. Specifically, if focuses on how subtle individual genetic variations caused by a single change in the coding sequence of a gene (a single nucleotide polymorphism, or SNP) influence a person’s response to different nutrients, and how those nutrients influence gene expression and function. Nutrigenomics seeks to understand how the food we eat interacts with our genes to create health or to influence susceptibility to disease.
