| Research Abstract |
The effects of food ingest time and food taste on psychological stress reduction was investigated at human level, in order to elucidate the effect of food palatability on psychological stress reduction. Ingestion of gamma-aminobutyric acid solution before psychological stress reduced the salivary chromogranin A and amylase activity levels, suggesting that intake time affect the degree of psychological stress. Measurement of brain waves was effective to evaluate the psychological stress response. In this study, there were not clear correlation between food ingestion based on individual palatability and the psychological stress reduction.
