How do you like these apples?
Apple is no longer the fruit of choice to deter visits to the doctor: New Zealand scientists have found that eating kiwi can improve mood in just four days, according to a study published in the British Journal of Nutrition.
“It’s great for people to know that small changes to their diet, like adding kiwifruit, could make a difference in how they feel every day,” said Tamlin Conner, co-author of the study. study, which teaches psychology at the University of Otago, in a press release. .
These beneficial effects on mental health are believed to be due to the fact that these fuzzy fruits are rich in vitamin C, known to improve mood and vitality, among other benefits.
To test the fruit’s purported mood-boosting effects, the ‘Kiwis’ team conducted a diet experiment on 155 adults with vitamin C deficiency levels.
Every day for eight weeks, participants received either a placebo, a 250 mg vitamin C supplement, or two kiwis, then were asked to report on their vitality, mood, sleep quality, and physical activity.
The researchers found that vitamin C and kiwi consumers both reported an improvement in their mood, but only the latter group reported feeling an increase in their perception of success.
Better yet, the Kiwi group reportedly experienced an improvement in vitality and mood in just four days, with effects peaking at around 14 to 16 days.
“Our participants had relatively good mental health at baseline and therefore had little room for improvement, but they still reported benefits from kiwifruit or vitamin C interventions,” said lead author Dr. Ben Fletcher, who carried out the research as part of his PhD at Otago.
Scientists have attributed these mental health benefits to the high vitamin C content of kiwifruit.
Interestingly, participants were given the SunGold variety – which has a yellow interior rather than green – and which is said to contain three times more vitamin C than oranges and strawberries, judging based on the weight of edible flesh.
Fletcher said that ultimately the results demonstrate how “what we eat can have a relatively quick impact on how we feel.”
“We encourage a holistic approach to nutrition and wellness, incorporating various nutrient-rich foods into your diet,” said the scientist.
