Hello all, Can you please tell me the awnser of following question:- 1.Cephalic phase: is the taste, smell, sight, hear or thought of any food triggers the cephalic phase.And the cephalic phase is heightened by hunger. 30 - 50% of all gastric secretions occur during the cephalic phase. Now suppose a person just taste, smell, see, hear or think of any food but don't take/consume it. What will then happen to the physiology of body? Will is assimilate/metabolize the inside food substances already present in body related to that food which is sensed? EG.; suppose a person sense(taste, smell,see, hear or think of) sugar or sweet, but don't consume it. Will it metabolize & lower blood sugar present in body or not? Best wishes.
