Nutritional Signaling

Meaning

Nutritional Signaling refers to the intricate biochemical communication network by which nutrient availability and composition directly regulate cellular processes, gene expression, and hormonal pathways. This concept highlights that food components are not merely energy sources but are potent information carriers that dictate cellular fate and function. Key pathways involved include the mTOR, AMPK, and sirtuin pathways, which sense the presence or absence of specific macronutrients and metabolites. Understanding nutritional signaling is crucial for optimizing metabolic health and influencing longevity-related pathways.
