How does aging affect perception of bitter, sour, and salty tastes?

• A. Increases
• B. Diminishes
• C. Remains unchanged
• D. Randomly changes

Answer: (B)

Aging generally reduces taste sensitivity because the gustatory system undergoes several changes. As people get older, there are fewer functioning taste buds on the tongue, taste receptor cells turnover slows, and saliva production often decreases. These factors make tastants less able to reach and activate taste receptors, which dulls the perception of basic tastes like bitter, sour, and salty. While individual experience can vary, the overall pattern is a diminished ability to taste these flavors rather than an increase, no change, or random fluctuations.
