The nutrients in regular diet are considered as environmental factors which have long-term effect on human genome. Personalized nutrition includes nutrigenetics and nutrigenomics studies that explains how food and genes interact and alters the gene expression. The “omics” studies are important tools to study the food-gene interactions. Most of the foods that are included in food habit of an individual exerts some physiological effects on the cells, organs or the whole body. These foods are referred as functional foods and the branch of science which deals with medicinal properties of nutrients is known as “nutraceuticals”. The functional foods may affect the genotype of different individuals in a different way and not all the foods are suitable for all the persons having various pathophysiological conditions. Function foods should be should be recommended based on one’s health, physiological condition, age and most importantly, their genetic setup. The concept of personalized nutrition was derived from “personal medicine” and in both cases regulation of gene expression is given priority based on the knowledge genomic studies. Understanding the complete molecular mechanism underlying the food-gene interaction and their effect to prevent the diseases like cancer, diabetes, obesity, thyroid, chronic degenerative diseases, etc, is required to assess the importance of personalized nutrition and functional foods as future tools for maintaining human health.
