title: Taste and food preferences as predictors of dietary practices in young women.
abstract: OBJECTIVE
  To investigate links between taste responses, self-reported food preferences and selected dietary outcomes in young women.
  
  
  METHODS
  Subjects were 159 women, with a mean age of 27.0 years. Taste responses were measured using aqueous solutions of 6-n-propylthiouracil (PROP) and sucrose. All subjects completed a 171-item food preference checklist, using nine-point category scales. Food preference data were reduced using principal components factor analyses, with the internal consistency of factor-based subscales established using Cronbach's alpha. Dietary intakes, available for a subset of 87 women, were based on 3 days of food records. Estimated intakes of carbohydrate, fibre and beta-carotene were the key dietary outcome variables.
  
  
  RESULTS
  Genetically-mediated sensitivity to the bitter taste of PROP was associated with reduced preferences for Brussels sprouts, cabbage, spinach and coffee beverages. Higher preferences for sucrose in water were associated with increased preferences for sweet desserts. Food preferences, in turn, were associated with measures of current diet. Reduced acceptability of vegetables and fruits was associated with lower estimated intakes of carbohydrate, fibre and beta-carotene.
  
  
  CONCLUSIONS
  Taste responses to sucrose and PROP were predictive of some food preferences. Food preferences, in turn, were associated with food consumption patterns. Given that taste responsiveness to PROP is an inherited trait, there may be further links between genetic taste markers, eating habits and the selection of healthful diets.
