Why does food taste bland when you have a cold?
Much of what we perceive as taste is actually smell.
The lack of desire to eat when ill causes food to taste bad.
A cold increases the rate at which taste buds die and replacement taste buds are formed at a slower than usual rate.
A cold causes taste receptors to malfunction.

Caffeine stimulates the nervous system.
Caffeine provides both calories and stimulates the nervous system.
Caffeine inhibits nerve impulses.
Caffeine provides the body with calories.
