Omics Technologies: The Most Convincing Tools for a (fully) Individualized Diet?

Abstract

DNA sequencing is becoming faster and cheaper by the day, and soon enough obtaining one’s complete genome will be an act as trivial as buying groceries at the supermarket. It is without surprise that so many start-ups and established brands sell their “do-it-yourself kit” to consumers who get, by means of a simple saliva sample, promises of an individualized diet that fits just as perfectly as Cinderella’s shoe, at least from a geno-pheno-typical standpoint. Theoretically, it sounds fantastic. But with the current practices in terms of nutritional genomics, these promises fall short.
