| Outline of Final Research Achievements |
In super-aged society, preventing lifestyle-related diseases by reducing salt and sugar intake is the social issue. The purpose of this study was to elucidate the mechanism of perception of taste intensity by age group. The taste intensity and reaction timing were analyzed by sensory evaluations. In addition, we analyzed the brain functions using a custom-made delivery system and functional MRI for taste and flavor. Perceived taste intensities were different between young and older adults. Our results offer a reference for ordinary citizens’ taste-intensity perceptions and could be usefully integrated into clinical examinations and societies.
