Everyone is familiar with the sensation of the mouth watering in anticipation of food, but this is not the body’s only response. At the same time, the pancreas starts to release insulin, ready to deal with the influx of glucose into the blood.

Now, a study from the University of Basel has shown that a short-term inflammatory response is responsible for this early insulin release.
