Rafi said smell also increase our appetite can you support this statement. How? (AS1)

a) Flavour of the food is the combination of both the smell and taste of the food. While taste distinguishes between the chemical that provide the salty, sweet, bitter and other tastes, the combination of taste and smell provides the enriching flavor to the food.

b) This can be supported by the example that a person with severe cold/cough faces difficulty in identifying the flavours and often has a funny/bitter taste due to difficulty in perception of the smell of the food.

c) Hence, we can say that although taste provides the usual characteristic to the food, the enriching smell of the food can help in increasing the appetite.
