What Experts Say About Sugar craving
- 1.Perception is the brain's transformation of electrical signals from detection (e.g., taste molecules on the tongue) into a conscious experience that guides actions.
- 2.The five basic tastes (sweet, sour, bitter, salty, umami) have innate evolutionary valences: sweet, umami, and low salt are appetitive, while bitter and sour are aversive.
- 3.Taste signals follow "labeled lines" from specific receptor cells on the tongue through distinct neural pathways to the brain's taste cortex, where meaning is assigned to each taste quality.
- 4.Taste perception is highly plastic and can be modulated by learning, experience, and the body's internal state, as seen with developing a liking for coffee or increased craving for salt when deprived.
- 5.Deep sugar cravings and preferences are significantly driven by a gut-brain axis circuit that recognizes sugar after ingestion (a postingestive signal), a process independent of tongue taste receptors.
- 6.Artificial sweeteners do not activate this crucial gut-brain circuit, which is why they cannot fully satisfy the body's craving for sugar like actual sugar does.
