Diet and energy metabolism affect gene expression, which influences human health and disease. Here, we discuss the role of epigenetics as a mechanistic link between energy metabolism and control of gene expression. A number of key energy metabolites including SAM, acetyl‐CoA, NAD + , and ATP serve as essential co‐factors for many, perhaps most, epigenetic enzymes that regulate DNA methylation, posttranslational histone modifications, and nucleosome position. The relative abundance of these energy metabolites allows a cell to sense its energetic state. And as co‐factors, energy metabolites act as rheostats to modulate the activity of epigenetic enzymes and upregulate/downregulate transcription as appropriate to maintain homeostasis. J. Cell.
