Nutritional Genetics and Nutritional Genomics
Nutrigenetics and nutrigenomics say about the relationship between nutrition, human genes and health. Nutrigenetics is the science of the effect of genetic variation on dietary response. On the other hand, Nutrigenomics is defined as the science of the role/effects of nutrients in gene expression at the molecular level. The science of nutrigenetics is involved in the mechanism, by which genetic variations define the individual’s risk of diseases, metabolic response and diet requirement. Nutrigenomics usually deals with the prevention or treatment of diseases. Nutrigenomics provides a simple understanding of how the chemicals in our food affect health by disturbing the gene expression and individual’s genome. There’s a risk of developing diseases, such as cancer. Generally nutrigenomics enhance the nutrition with respect to the genotype and how the body responds to the diet.
