Nutrigenomics expands our knowledge of the mechanisms by which diet influences the metabolic pathways that underlie homeostatic control. This data can then be used to identify naturally occurring chemicals in foods that could prevent the onset of diseases such as obesity, type 2 diabetes and cancer. Nutrigenomics is a field of development that aims to identify the relationship between genotypes and factors related to nutritional processes. Nutrigenomics is one of the first areas in which services and products are offered directly to consumers. It faces major ethical challenges related to the validity and usefulness of nutrigenome tests and the scientific statements sold to the
public become.
In addition, nutrigenomics, an area of research that depends on the collection and storage of a wide variety of human genetic samples, requires consideration of various research ethics issues, including informed consent, data protection, and ownership of genetic material. Nutrigenomics is essentially becoming an instrument for nutritional advice. When a dietitian has access to a patient’s genetic information, they can start giving the necessary advice about the patient’s diet while taking genetic analysis into account. Genetic analysis provides dieticians with huge amounts of data that a simple medical history cannot keep up with

Kaput notes that dietary intake estimates, although banal to the outside world, could represent one of the biggest obstacles to the success of large-scale studies of human nutrition. Korthals questions many of the assumptions about nutrigenomics, including in particular the idea that nutrigenomics is necessarily linked to promoting the health of motivated people. The potential of preventive applications of nutrigenomics in a public health model is then discussed, together with some potential applications of nutrigenomics. Fenech developed the concept of “Genome Health Nutrigenomics,” a science that investigates how a lack or excess of nutrients can cause genome mutations at the base sequence or chromosome
level.
In addition to the overall positive media assessment of nutrigenomics, there were stories that focused on the lifestyle and diet of celebrities and identified nutrigenomics as a new food trend. This chapter sets out normative assumptions on health and food concepts that have been advocated by many nutrigenomics researchers. Although diet is indeed an important factor, nutrigenomics addresses health without taking into account other key factors such as lifestyle, medical history, health status, cultural identity, personal preferences, patients’ willingness to change, and even their own health goals. Nutrigenomics will help initiate the development of new functional foods and genome health supplements that can be mixed and matched so that total nutrient intake is adequately tailored to a person’s genotype and genome status
.Using harmonized protocols for nutritional intervention studies with a focus on nutrigenomics helps identify a wider range of critical study parameters and reduce background noise from confounding variables and factors. At a simpler level, nutrigenomics (or nutritional genomics) is defined as the study of the effects of foods and food ingredients on gene expression, with the goal that understanding the links between the two can lead to diet plans that lead to better health. Nutrigenomics is the study of all genetic factors that influence the biological response to diet, as well as the effects of diet on gene expression. The chapter concludes with suggestions on how the application of nutrigenomics can be extended to a larger number of food types and what ethical and cultural consequences
this entails.
However, that doesn’t mean that nutrigenomics can’t be translated into public health measures, but it does mean they haven’t happened yet. With ever lower prices for analyzing SNPs among individuals, the potential to optimize nutrition based on population-level nutrigenomic approaches seems truly impressive. Nutrigenomics data can also be used to determine whether people have specific tendencies to which they
adapt Can.
