The brain interacts directly with the taste receptors of the tongue. There are several types of receptors, each dedicated to a specific taste (salty, sweet, fatty, bitter, etc.). Those dedicated to the detection of sugary flavors, the Glut receptors, convey their data directly to the brain through the glossopharyngeal nerve, bypassing the metabolic pathways. Let us point out, on this subject, that in the entire animal kingdom, the mouth is located in the vicinity of the brain. The calibration of the receptors is crucial, especially in children. Saturating their receptors by using too much sugar (or alt, for that matter) has significant implications for their health as adults as their reference shall be excess. Accustomed to extra-sweet or -salty foods, they will tend to keep overindulging in salt and sugar. This often happens with children brought up by their grandparents, as it is a well-known fact that over time, the taste receptors lose their sensitivity, so elderly people use more sugar and salt.
