Effects of sucrose detection threshold and weight status on intake of fruit and vegetables in children.
Sommaire de l'article
Past research on the relationship between taste sensitivity and fruit and vegetable (FV) intake in children has focused on sensitivity to bitter taste. The effects of sensitivity to sweet taste on intake of FV have never been investigated. Furthermore, the effects of children's weight on intake of FV are inconclusive. This study measured the effects of Sucrose Detection Threshold (SDT) and weight status on intake of FV in children. The participants of this study were 99 children between 5-9 years old. Parents reported their own and their children's 24 hour intake of FV and completed a measure of children's sensory sensitivity. Children completed the triangle test with suprathreshold concentrations of sucrose ranging between 0.2% and 1.6%, in 0.2% increments. Two MANCOVAs showed that, controlling for parental intake and children's sensory sensitivity, there was a main effect of SDT on intake of fruit (p < 0.05), which was exclusive to non-astringent fruit (p < 0.05), and cruciferous vegetables (p < 0.01). Weight status had no effect on intake of FV. Mechanisms behind the effects of SDT are discussed in the context of past research on bitter taste sensitivity.
