Decreased Taste Sensitivity

Smoking can impair the function of taste buds, making food seem less rich. This is especially noticeable with sweet and sour flavors. Research shows that smokers have lower sensitivity to basic tastes compared to non-smokers.

Loss of Smell

Nicotine and other substances can reduce the sensitivity of olfactory receptors — and smell is a crucial part of food perception! Smokers often experience a decreased sense of smell.

Dry Mouth

Smoking reduces saliva secretion, making food seem drier and less appetizing. Data indicate a link between smoking and dysfunction of the salivary glands.

Change in Taste Preferences

Many smokers begin to prefer stronger flavors, such as salty, spicy, or fatty. This is because muted receptors do not perceive subtle tastes as effectively.

Recovery After Quitting

Once a person quits smoking, their receptors start to recover. People often notice that their favorite foods become more flavorful. Taste and smell receptors begin to regenerate as early as 48 hours after smoking cessation.
