Saliva and Taste.

Radha and Geeta were having lunch in the school canteen one day.

Radha had brought rotis and spicy subji while Geeta had brought vegetable mixed rice and they shared the food with each other. The aroma of the mixed rice was so good that Radha started enjoying the meal, but Geeta could not relish the same. They started discussing about it

Radha: “What happened to you, Geeta? Why aren’t you eating properly?”

Geeta: ” I don’t know why I don’t have the urge to eat”

Radha: ” The aroma and taste of the food is very amazing;mouth-watering and your mom has taken the effort to get it ready for you. Please let us not waste it”.

Geeta: My mouth is dry and feels no taste”

The teacher who was passing by, heard the conversation and stopped to talk to the girls.

Teacher:” Geeta, did you have cold, influenza or any viral infection recently”?

Geeta: ” Yes Ma’am, I had cough last week. I consulted a doctor, took medicine and am better now. “

Teacher:” This is the reason for your dry mouth which is the side effect of the medicine that you have taken. The salivary gland is not producing adequate saliva and hence the mouth is dry”

Radha: Is this the reason for Geeta not being able to feel the taste of the food?”

Teacher: ” Yes, I can explain. Take a towel and pat your tongue dry with it. Place some veggies and some mixed rice one after another and check the taste. What do you taste?”

Both girls nodded their heads left and right and said in the same voice” no taste at all”

Teacher: “Drink some water now and then taste the food”

Now Radha jumped in glee shouting, “the rice is yummy, the vegetable is awesome, spicy and aromatic”

Geeta:” But I am not able to enjoy as much as Radha. why Ma’am?

Teacher: That is because our food has certain chemicals responsible for the taste which gets dissolved in the saliva. This is then deducted by the receptor in taste buds. When medicines are taken, they cause drying up of saliva in the mouth. As saliva has got dehydrated there is no solvent for the taste stimuli and hence, we do not identify the tastes.

Geeta: “Will I be able to get back to normalcy and how long would it take?”

Teacher: This will happen very soon and Geeta will be fine early.

The girls were happy, thanked the teacher for the explanation and got ready to move to the classroom.
