Eating kiwi can get you out of a bad mood in just four days, a study has revealed.
The green berry fruit is high in vitamin C, which has long been known to improve well-being.
But now researchers believe the fruit gives us a faster and longer-lasting boost than vitamin C supplements.
The team, from the University of Otago, New Zealand, carried out an eight-week dietary intervention in 155 adults with low vitamin C levels.
Participants took a vitamin C supplement, a placebo, or two kiwis a day and then reported on their vitality, mood, sleep quality, and physical activity via smartphone surveys.

The results, published in the British Journal of Nutrition, showed that kiwis improved vitality and mood within four days, with the boost effect peaking between 14 and 16 days.

Vitamin C supplements, on the other hand, marginally improved mood until day 12.
Lead author Dr Ben Fletcher added: “This helps us see that what we eat can have a relatively quick impact on how we feel.”
