during severe cough and cold we don't get the taste of food
Answers
When we're sick, our noses are often blocked with mucus. Also, the tissues inside our nose can become swollen and inflamed. This prevents us from smelling properly. Because your sense of smell is so tied to your sense of taste, if you can't smell things properly, you won't be able to taste them properly, either.
Answer:
Most importantly, it is needed to understand that the flavor of food involves both smell and taste. In fact, around 80% of our taste is related to smell. When you have a cold, the swelling cause inflammation and obstruction, which impairs your smell.
The flavor of the food is produced only after the taste is combined with the smell. So, if a fluffy nose impairs your sense of smell. It will also decrease your perception of taste.
