Nutrigenetics explains the relationships between genes, diet, and health outcomes. Population-based dietary recommendations aren’t adequate for all individuals since people respond differently to diets. Nutrigenetics bases dietary recommendations on genetic predisposition to the disease. Once personalized nutrition is integrated into routine care, patients can be genotyped for specific genetic variations, made aware of their chronic disease risk and nutrient deficiencies, and given strategies to dramatically reduce their risk.
Nutrigenomics is the study of how genes and nutrients interact at the molecular level and it can be helpful in finding out eating behaviors, food reactions, matching diet, nutritional needs and metabolic health factors. Nutrigenomics is already driving the next stage of growth for the nutrition industry. Nutrigenomic technology has been advanced, and nutrition companies are increasingly responding to opportunities. However, there is a lot more research to be done to fully provide the concept of nutrition and the role of genetics.
