Summary
Sandell and Breslin's 2006 commentary suggests that natural genetic variation in taste-receptor genes, particularly those encoding bitter taste receptors, explains why individuals differ substantially in their ability to detect and perceive bitter compounds associated with potentially toxic plant secondary metabolites. This variation may have implications for food selection, intake of protective phytochemicals, and personal risk from foods containing high levels of anti-nutritional or toxic compounds. The work bridges sensory genetics and food toxicology in human populations.
Regional applicability
The genetic variation described is population-wide and not geography-specific; findings on taste-receptor polymorphisms apply equally to United Kingdom populations and other human groups. However, practical implications may vary depending on local dietary exposures to foods rich in bitter compounds (e.g. brassicas, dark leafy greens, coffee, tea).
Key measures
Taste-receptor gene variation and bitter taste perception phenotypes
Outcomes reported
The study examined how genetic polymorphisms in taste-receptor genes influence individual differences in the perception of bitter compounds, which may reflect the presence of toxic or anti-nutritional substances in foods.
