Nutrigenomics Studies to Explore Antiaging: Drosophila Approach

Abstract

The field of Nutrigenomics has always been of interest to scientists as it integrates the field of nutrition and the “-omics”. Drosophila melanogaster is the most suitable model for this study as appx. 60% of human diseases have homology in flies. Ageing is a complex mechanism that involves several pathways, and only a small fraction of these pathways has been studied in detail. There have been proofs that nutrition can extend or reduce life span. The epigenetic mechanisms involved have also been explained to an extent. Certain diseases that manifest due to ageing can potentially be delayed with the right nutrition and diet. Antioxidants and polyphenols help reduce the oxidative stress, and this study is important as oxidative stress is one of the main reasons of ageing. Many theories for ageing have been hypothesised and are under study. Nutrigenomics might be the break-through that changes the perception of “diets” and how beneficial the right diet can be on human health.
