Quick Facts

  • Kiwis offer a potent source of vitamin C: This essential nutrient has been linked to improvements in mood, vitality, and reduced depression.
  • The study demonstrated rapid effects: Participants consuming two kiwis daily experienced noticeable mood and energy improvements within four days, peaking at around two weeks.
  • Whole food sources may be optimal: While vitamin C supplements offered moderate benefit, nutrient-packed whole foods like kiwi appear to yield the most significant psychological gains.

Understanding the Kiwi-Mood Connection

Previous research has established a link between vitamin C and mental health. This latest study explored the speed at which mood improvements might occur following increased vitamin C intake. In an eight-week experiment, researchers at the University of Otago observed 155 adults with low vitamin C levels. Participants were assigned to receive either vitamin C supplements, a placebo, or two kiwi fruits daily, tracking their well-being via smartphone surveys.

Beyond Just Vitamin C

While rich in vitamin C, kiwi fruit contains a combination of beneficial nutrients. Researchers suggest that fiber, folate, and other compounds likely contribute to kiwi’s mood-boosting effects. This highlights the overall importance of including nutrient-dense foods within a balanced diet.
