Genetics in Dietary Analyses

Show Summary Details

Preview

Nutritionists have long known that differences exist among individuals in their responses to the same dietary change, and it was assumed that many of these differences were due to unmeasurable genetic factors. These genetic factors can now be measured directly, and the incorporation of genetic markers into studies of diet and disease creates a wealth of opportunities that did not exist even twenty years ago. This chapter discusses the study of gene-diet interactions, the use of genetic markers to inform diet and disease relationships (Mendelian randomization), and the classification of outcomes using genetic characteristics.

Keywords: genetic factors; genetic markers; gene-diet interactions; disease; mendelian randomization
