❓ why
Why can some people taste bitterness more strongly than others?
Human BiologyGenetics
Quick Answer
Bitterness sensitivity varies because taste receptor genes differ from person to person. Variants in genes such as TAS2R38 change how strongly bitter compounds are detected.
The Full Story
Taste buds contain receptor proteins that respond to specific chemicals in food. Some people inherit receptor variants that make them especially sensitive to bitter compounds such as phenylthiocarbamide, or PTC, and related substances. This can affect food preferences, including vegetables like Brussels sprouts and cabbage. Variation in bitter taste perception is a classic example of how genetics influences behavior and diet.
