Nutrigenomics could be defined as the amalgamation of nutrition science and genomics. It is an emerging field of science that studies how nutrition affects a person’s or a population’s health at the level of genome, proteome, and metabolome. It also takes into account numerous environmental variables such as age, smoking habits or alcoholism. The valuable information could then be exploited to customize dietary components in a bid to achieve the twin goals of healthy living and disease prevention. The increasing ease with which large scale of data could now be obtained and the realization that each individual’s metabolism and genetic make-up is unique, nutrigenomics is steadily gaining popularity.
