This study examined percentage of tasters and non tasters for phenylthiocarbamide (PTC) in 325 subjects of Hazara division in Khyber Pakhtun Khwa Province of Pakistan. The percentage of tasters was 87.7 and that of non-tasters 12.3. The sex, age, food preferences (like vegetables, meat, pulses, hot and very hot tea) indicated no significant difference between tasters and non-tasters. However, tasters showed affinity towards salty food, whereas non tasters showed easy acceptance to bitter medicines as compared to the tasters. In addition higher percentage of super tasters was found among Swatis and tasters among Tanolis. The genotype and gene frequencies of tasting and non-tasting ability for PTC indicated minute significant difference between the parental and offspring generation.
