| Outline of Final Research Achievements |
To determine how to effectively increase adolescents’ vegetable intake, we studied bitter taste sensitivity and the bitter taste sensitivity gene as evaluation criteria. We also used a masking reagent for fruit sweetness in an intervention trial study of fresh fruit and komatsuna (Brassica rapa L. var. perviridis) juice, and verified that this had an effect. The food preference and eating behavior results indicated that the environmental factors of food environment and lifestyle had a greater influence on vegetable intake than bitter taste sensitivity and the bitter taste sensitivity gene did. Furthermore, results of the intervention trial study showed normalization of bowels and food intake, and increased isothiocyanate excretion in the urine. Using fresh fruit and komatsuna juice was found to be effective for nutrition education programs for adolescents.
