The occlusion mastication system has extradigestive functions; however, whether liquid feeding evokes stress responses remains unclear. In this study, reactions to low masticatory performance were analyzed using a diet-alteration model in Wistar rats. Seven days after the diet of the rats was changed from solid to liquid, serum epinephrine and norepinephrine concentrations were found to be elevated by 205% and 158% compared to baseline values, respectively. Superoxide production by peritoneal neutrophils was higher in rats fed with a liquid diet than in those fed with a solid diet. Serum superoxide dismutase activity (i.e. the potential to eradicate serum superoxide) was lower in rats fed with liquid than in those fed with a solid diet, indicating that the former experienced oxidative stress. Conversely, the oxidative stress was removed following reversion of the liquid diet to solid diet. These results suggest that liquid diet mastication can cause mental stress, including an oxidative stress response.
