Abstract

During the past two decades, there have been numerous developments in the genetic and genomic technologies enabling us to understand complex biological systems in an integrative manner through holistic approaches in research. Since the sequencing of the human genome, efforts are made to identify the number of the genes and their functions. The tools for determining the functionality of the genes are just beginning to appear. Initially the methodologies to identify functionality of the genes were largely based on comparative studies between model organisms. The very high number of genes with unknown functions demanded the need to develop new methods and technologies that may be helpful in assigning functions to the identified genes. Advancements in computing techniques and software opened the door for new technologies to be able to take an applied approach by studying biomolecules needed for proper functioning of the cell and take a holistic approach in biomedical research. Besides genomics, several other technologies are developed in the last decade that take an ‘omics’ approach, i.e., an integrated approach in the study of cell function. It is hoped that the applied integrative omics approaches may be helpful in establishing cause and effect relationships between genotype and phenotype. These ‘omics’ approaches include the integration of genomics, proteomics, transcriptomics, metabolomics and other omic technologies to do the non-targeted studies of biomolecules involved in the proper functioning of the cells and their responses to environmental changes. The applications of these technologies have been also utilized in the field of nutrition for studies on how nutrients and other metabolites effect the proper functioning of the cell. With these emerging techniques to understand the molecular functioning of the body, it is envisaged that they might be helpful to give personalized medical care and dietary advice to people based on their individual genotypes in the future. Whilst nutritional genomics is a rapidly growing field in the nutritional sciences focusing on the diet-gene relationships, there is an increasing understanding that other technologies will also be crucial in understanding the whole biological processes involved in metabolism of food. In this chapter I wish to outline the use of contemporary technologies that are involved in establishing the intricate linkages between diet and the genes, and the ethical challenges they raise in their applications.
