TAS2R38 (taste receptor gene)

TAS2R38 is a gene that produces a receptor protein on taste buds, playing a key role in how we perceive bitterness in foods. Variations in this gene influence sensitivity to bitter compounds like those in vegetables such as broccoli or Brussels sprouts. Some people have versions of TAS2R38 that make them very sensitive to bitterness, which can affect their food preferences, while others have versions that make them less sensitive. This genetic difference helps explain why some individuals enjoy bitter foods, and others tend to avoid them.
