Consuming two kiwifruits daily can improve overall mood, particularly for individuals starting with moderate mood disturbance.
The research study investigated the potential mood-enhancing effects of kiwifruit, involving a sample group of 35 young adult males who were supplemented with either half or two kiwifruits a day for 6 weeks. Through this observational period, their moods were evaluated with the use of Profile of Mood States questionnaires that were administered at the start and end of the intervention.
In the results discussion, it was noted that there was no observable effect on overall mood for the group that consumed half a kiwifruit daily. However, interestingly, for those who consumed two kiwifruits daily, there was a trend towards a decrease in total mood disturbance as well as depression. This was especially significant among participants with higher initial mood disturbance, showing decrease in mood disturbance and fatigue, and increase in vigour. This research also observed a significant increase in dietary vitamin C intake and corresponding plasma levels among the participants. There was no apparent effect of consuming two kiwifruits daily on the mood scores of participants with low initial mood disturbance.

In total, 776 patients with newly diagnosed trigeminal neuralgia in each cohort with similar baseline characteristics were enrolled in the study. The acupuncture cohort had a reduced risk of depression compared to the non-acupuncture cohort. Kaplan–Meier analysis also revealed that the cumulative incidence of depression was significantly lower in the acupuncture cohort during the 13-year follow-up period. In particular, the beneficial effect of acupuncture was a decrease in the risk of depression among TN patients aged 50– 69 years who had also used carbamazepine.

The pathophysiology of these disorders may be associated with glutamate dysregulation, marked by a high rate of glutamate release and elevated expression of glutamate receptors and glutamate transporters in the CNS. The ability of acupuncture stimulation to modulate glutamate receptor and EAAT expression suggests that the treatment effects of acupuncture are underpinned by its intervention in the dysregulated glutamate system. Further preclinical and clinical studies are needed to clarify the possible mechanisms of acupuncture in these neuropsychiatric disorders and to establish protocols for treatment guidelines.
