Outline of Final Research Achievements

In the present study, we examined the effects of preference of flavor orduring ingestion behavior by monitoring the electrocardiogram (ECG), the surface electromyogram (EMG), and electroencepharogram (EEG). We investigated chewing behavior during ingesntion of the two types of gum, favorable flavor gum and unfavorable flavor gum in adult human subjects.
In the results, we revealed that the preferred food intake showed an improvement in chewing power and it became clear that autonomic nervous system / brain activity showed a relaxed state. In conclusion, food preference during ingestion behavior, it was suggested that it helps improve the function in case.
