WHY do people taste food?

Taste “notifies” the brain that food containing certain substances is coming into the body. Thus, putting something sweet in your mouth triggers a reflex that induces the islet cells of the pancreas to produce insulin and the liver to break down glycogen, releasing glucose into the blood.

Above all, taste is a signal to determine the suitability of food, to distinguish ripe fruit from unripe or spoiled fruit.
