Short-term vegetable intake by young children classified by 6-n-propylthoiuracil bitter-taste phenotype

摘要: Background: Genetic variation in sensitivity to the bitterness of 6-n-propylthiouracil (PROP) is thought play a role acceptance and rejection bitter-tasting vegetables by young children. Objectives: We investigated relation between PROP bitter-taste phenotype consumption hypothesized that nontasters would give higher hedonic ratings consume more bitter than tasters PROP. Design: Sixty-five preschool children were identified as (n = 24) or 41) Children allowed select from among 5 types (black olives, cucumbers, carrots, red pepper, raw broccoli) free-choice intake test vegetables. Results: The nontaster consumed did taster during (0.91 servings compared with 0.48 servings; P < 0.05). This difference reflected (olives, cucumber, (P Only 8% no 32% 0.03). also liked broccoli Conclusions: vegetables, particularly tasting, test. These novel findings suggest contributes development vegetable patterns early childhood.
