Abstract
ABSTRACT:
 The physiology of human taste enjoyed an unprecedented expansion of 
knowledge brought forward by modern genetics and molecular biology. In 
the last 10 years the cellular organization of taste receptors from 
taste buds distributed in the various papillae of the tongue and the 
soft palate was enlightened. This molecular revolution rapidly expanded 
over and above the tongue, since several papers reporting the presence of taste receptors in non-gustatory tissues (like the gut and the brain)
 appeared. Hence the issue of perception of food molecules is not 
anymore confined to the field of nutrition and food preferences, but is 
rapidly expanding to gastrointestinal function and, possibly, to gut 
dysfunction too. In children functional gastrointestinal diseases are strictly correlated to food preference and food aversion
 and up to now the tools to face these kind of problems were the basic 
nutritional requirements, familial good sense and a lot of patience: 
blunt tools to face very common and disturbing complaints. The
 fact that taste receptors are expressed down the whole of intestinal 
tract is of particular interest, because of their possible role in 
digestive behavior and absorption of nutrients; therefore
 recent and future discoveries in this field will make possible to 
fine-tune new, sharper tools to face children with functional 
gastrointestinal diseases.
