Nutrigenomics (a combination of the words nutrition and genome) is the study of how the foods we and our pets eat "speak" to our cells to regulate gene expression, which in turn plays a huge role in determining whether a person or animal will live a life of vibrant health, or one plagued by illness. Scientists now know that while we can't change the genes we are born with, we can change how those genes behave, which is exactly what authors W. Jean Dodds, DVM and Diana Laverdure show us how to do in their newest book, Canine Nutrigenomics: The New Science of Feeding Your Dog for Optimum Health from Dogwise Publishing. (see: Google Books)
