"Kiwifruit: A Quick Mood-Boosting Superfood"

A study from the University of Otago found that kiwifruit rapidly improves mood and vitality, with effects noticeable in just four days, surpassing those of vitamin C supplements. The research involved an 8-week intervention with 155 adults with low vitamin C levels, comparing the effects of vitamin C supplements, placebo, and kiwifruit. Kiwifruit supplementation led to a significant boost in vitality, mood, and overall flourishing, highlighting the advantages of whole foods over supplements for mental health. The study also introduced a novel method using intensive smartphone surveys for real-time tracking of mood changes.
