Why do we lose our sense of taste when suffering from Cold?
A human individual is endowed with the capacity to detect up to 10,000 smells. Our sense of smell is responsible for about 80% of what we taste. The tastebuds present on our tongues are limited to only the basic sensations such as sweet, salty, sour, bitter and cussed. Other flavours that we experience come from smell. This is why, when our nose is blocked, as by a cold, most foods seem bland or tasteless.
