Food is vital for our sustenance and health. However, the significance of food goes beyond its role of regulating metabolism and providing energy. Food contains information through which it interacts with our genes thereby affecting their function. It is a study about how our genetic code influences our nutrition and vice-versa. This discovery is called “nutrigenomics”. Earlier, nutritional science was limited to identifying essential vitamins and nutrients and their insufficiency. Diagnosis was based on lack of such nutrients and treatments were universal. However, over the years nutritional science has undergone a paradigm shift in focussing its attention towards molecular biology and genetics. The completion of many genome projects ha...
