New study sheds light on the role of furry fruits in improving mental health
A new study published in The British Journal of Nutrition has found that kiwifruit are powerful mood boosters and can improve “vitality and mood in as little as four days.” With this the study by researchers from the University of Otago has found an effective way for people take care of their well-being. “It’s great for people to know that small changes in their diet, like adding kiwifruit, could make a difference in how they feel every day,” Co-author Professor Tamlin Conner, of the Department of Psychology has said.
What are furry fruits?
Furry fruits” typically refer to fruits with a fuzzy or hairy outer surface. One common example is the kiwifruit, known for its brown, fuzzy skin and vibrant green flesh. The tiny hairs on the kiwi skin are edible, and the fruit offers a sweet and tangy flavor. Another example is the rambutan, a tropical fruit with a hairy red or yellow skin and translucent, juicy flesh inside. These fruits often have unique textures and flavours , making them not only visually distinctive but also appealing to those seeking diverse and exotic taste experiences.
How did the researchers zero in on furry fruits?
The researchers connected the link between vitamin C and its impact on mental health. Vitamin C intake has been associated with improved mood, vitality, well-being, and lower depression, while vitamin C deficiency is associated with higher depression and cognitive impairment. A total of 155 participants were studied. The participants took daily either a vitamin C supplement, placebo, or two kiwifruit. They then reported their vitality, mood, flourishing, sleep quality, sleep quantity, and physical activity using smartphone surveys. The researchers found kiwifruit supplementation improved vitality and mood within four days, peaking around 14–16 days, and improved flourishing from day 14. Vitamin C, on the other hand, marginally improved mood until day 12.
Role of vitamin C in improving mood
Vitamin C, an essential nutrient found in fruits and vegetables, plays a crucial role in mental health. As an antioxidant, it helps combat oxidative stress, protecting the brain from free radical damage linked to cognitive decline and mental disorders. Additionally, vitamin C supports the synthesis of neurotransmitters like serotonin, vital for mood regulation. Adequate intake enhances cognitive function, memory, and concentration. Its anti-inflammatory properties further contribute to overall brain health. While not a cure for mental health conditions, maintaining sufficient vitamin C levels through a balanced diet may positively influence emotional well-being and cognitive resilience.
Fruits vs. vitamin C supplements: Which is better?
Our study suggests that kiwifruit consumption, and to a lesser extent vitamin C supplementation, can lead to mood-related improvements in a relatively short time (from 4 to 16 days), even in a relatively healthy population with good mental health,” the researchers have said. “Whole food sources (kiwifruit) showed greater and more consistent improvements over time than vitamin C alone, and improvements were more notable for individuals who had consistently low vitamin C levels at baseline,” they added.
