Nutrigenomics is the study of the effects of foods and food constituents on gene expression.
It is about how our DNA is transcribed intomRNA and then to proteins and provides a basis for
understanding the biological activity of food components. [1] Nutrigenomics has also been
described by the influence of genetic variation on nutrition by correlating gene expression or
single-nucleotide polymorphisms with a nutrient'sabsorption, metabolism, elimination or
biological effects. By doing so, nutrigenomics aims to develop rational means to optimise
nutrition, with respect to the subject's genotype.
By determining the mechanism of the effects of nutrients or the effects of a nutritional regime,
nutrigenomics tries to define the causality|relationship between these specific nutrients and
specific nutrient regimes (diets) on human health. Nutrigenomics has been associated with
the idea of personalized nutrition based on genotype. While there is hope that nutrigenomics
will ultimately enable such personalised dietary advice, it is a science still in its infancy and
its contribution to public health over the next decade is thought to be major.
