Vitamin D: A master example of nutrigenomics.

Nutrigenomics attempts to characterize and integrate the relation between dietary molecules and gene expression on a genome-wide level. One of the biologically active nutritional compounds is vitamin D, which activates via its metabolite 1α,25-dihydroxyvitamin D (1,25(OH)D) the nuclear receptor VDR (vitamin D receptor). Vitamin D can be synthesized endogenously in our skin, but since we spend long times indoors and often live at higher latitudes where for many winter months UV-B radiation is too low, it became a true vitamin.
