Kiwifruit Consumption Boosts Mood and Vitality in Days, Study Finds

The study underscores the potential benefits of consuming whole foods over supplements, with kiwifruit showing significant mood-related improvements within four days.

Kiwifruit consumption can improve vitality and mood in as little as four days, according to a study by researchers from the University of Auckland and the University of Otago.
The study involved an 8-week dietary intervention in 155 adults with low vitamin C, who were given either a vitamin C supplement, placebo, or two kiwifruits daily.
Participants reported their vitality, mood, flourishing, sleep quality, sleep quantity, and physical activity using smartphone surveys.
Kiwifruit supplementation improved vitality and mood within four days, peaking around 14-16 days, and improved flourishing from day 14.
While vitamin C tablets showed some improvements, the study underscores the potential synergistic effects of consuming whole foods like kiwifruit.
