Abstract: The field of nutrition research has traditionally focused on the effects of macronutrients and micronutrients on the human body. However, it is now increasingly clear that each individual's genetic makeup varies, which influences their response to food. Nutrigenomics (encompassing nutrigenetics and nutrigenomics) is dedicated to exploring the interactions between an individual's genetic makeup, diet, and health outcomes. Nutrigenetics studies the impact of genetic variations on an individual's response to dietary nutrients, while nutrigenomics investigates how dietary components affect gene regulation and expression. These disciplines aim to understand the effects of diet on the genome, transcriptome, proteome, and metabolome, and to uncover the underlying mechanisms by which diet influences gene expression. Nutrients can lead to changes in gene expression through epigenetic modifications, such as DNA methylation and histone modifications. The goal of nutrigenomics is to develop personalized dietary plans based on an individual's unique metabolic profile, gut microbiome, and genetic makeup to prevent disease and promote health. By combining the practicality of personalized nutrition with knowledge of the genetic factors underlying health and disease, nutrigenomics has the potential to revolutionize the field of nutrition. Therefore, nutrigenomics offers a highly promising approach to improving health outcomes (in terms of disease prevention) through personalized nutritional strategies based on individual genetic and metabolic characteristics.
