Nutrigenetics

Precision Nutrition is a relatively new term that can be considered as a way to use information we continue to learn about our genomics in order to customise nutritional advice. Progress in scientific and medical research has led to understanding our biology as a whole system, known as the -omics era. The knowledge we can apply from -omics technology, together with understanding of nutrient-gene interactions has developed a field known as Nutritional Genomics.

At present, the nutritional genomic relationship is made up of two related but distinct fields namely, Nutrigenomics and Nutrigenetics. Nutrigenomics focuses on how diet affects gene expression. Nutrigenetics focuses on how the gene variants in our DNA influences our response to nutients i.e. how our genes determine the effects what our food has on us.  Both aim to elucidate how the genome interacts with nutrition to influence genotype to optimise health through the application of personalised and precision nutrition.
