Over the last few decades, much attention has been gained by nano-based medicines (Dhakad et al. 2013; Maheshwari et al. 2012) and omics-based technologies, although the nano delivery of drugs using different techniques (Maheshwari et al. 2015; Tekade and Chougule 2013) and omics developments are two different aspects. In recent times, “omics”-based sciences have been attaining momentous attraction by the scientific community. Nowadays, the impact of diet and dietary constituents on human health has been revealed, and the areas related to it are nutrition, nutrient-gene interaction, and nutritional biomarkers. In addition, some non-essential nutrients and bioactive food components are also altering genetic and epigenetic events in the human body (Xu 2017).
