Conventional multi-cell type (bulk) analyses obscure cellular heterogeneity, while animal and standard in vitro models often fail to replicate human physiology. Single-cell omics technologies{--}such as single-cell RNA sequencing, as well as single-cell?resolved proteomic and metabolomic approaches{--}enable high-resolution investigation of nutrient?cell interactions and reveal mechanisms at a single-cell resolution. When combined with advanced human-derived in vitro systems like organoids and organ-on-chip platforms, they support mechanistic studies in physiologically relevant contexts. This review outlines emerging applications of single-cell omics in nutrition research, emphasizing their potential to uncover cell-specific dietary responses, identify nutrient-sensitive pathways, and capture interindividual variability. It also discusses key challenges{--}including technical limitations, model selection, and institutional biases{--}and identifies strategic directions to facilitate broader adoption in the field. Collectively, single-cell omics offer a transformative framework to advance human-centric nutrition research.}, keywords = {Nutrition research; organoids; personalized nutrition; 3Rs; single-cell omics}, url = {http://repositorio.uneatlantico.es/id/eprint/17867/} }
