Food has tantalizing effect in human history as in the start of the human evolution. Each individual has gene variation in which the protein sequences are affected and most likely, the nutrient requirements, the likeliness of disease are varied to the appropriateness of the genetic makeup in oneself.
Dietician Sheela Seharawat, also the founder of Diet Clinic says, nutrigenomics is the term used for the study of genes and nutritional requirements. It has been found that food can interact with single nucleotide polymorphisms (SNIPs) in our DNA and activate certain genes. Many diseases, however, are much more complex, DNA diets impacts heavily on these diseases, and for overall health, require dedicated, focused studies in genetics and epigenetics, as well as increased understanding of how genes, proteins, and epigenetic changes interact within networks and pathways.
