ABSTRACT

In the scientific world, health and diet have taken center stage. Considerable progress has been observed in the notion of healthy food in recent years, and study on the subject has a significant impact on today’s population. People have known that the food we consume has an effect on our health since the dawn of time. The human genome project, as well as advancements in science, have raised many questions about the relationship between what we consume and our genetic composition. The variations in genetics affect the food tolerances in various human population groups and may also impact dietary requirements, originating the new area of nutritional genomics and increasing the possibility of altering nutritional intake for the best possible prevention of diseases based on an individual’s genome. Nutrigenomics deals with the interactions of genes and nutrients at molecular levels with the help of epigenomics and epigenetics. The common ground for pharmacogenomics and nutrigenomics is individual genetic composition. Each human being is genetically as well as phenotypically unique. The genetic composition and diet directly influence certain chronic diseases including 226cancer, obesity, hypertension, and diabetes. The relationship between food and genetics contributes to the array of disease risk factors in response to nutritional factors with the potential to boost or protect against disease. The understanding of these gene–nutrient interactions will benefit in the provision of personalized diets based on each person’s genotype. As a result, it will be feasible to treat existing ailments or avoid future illnesses.
