London: Eating two kiwis a day could significantly improve digestion and support immune health, according to UK-based surgeon Karan Rajan, who highlighted research-backed benefits of the nutrient-rich fruit.
Kiwis, packed with vitamin C, fibre and antioxidants, are emerging as a simple dietary addition that may outperform some common fibre supplements in improving gut function.
How kiwis improve digestion
According to Dr Rajan, eating two kiwis every morning for four weeks can lead to noticeable improvements in bowel movements and overall gastrointestinal comfort.
A large randomised trial involving 184 participants compared kiwi consumption with psyllium husk, often considered a gold-standard fibre supplement.
Key findings included:
- More regular and complete bowel movements
- Improved stool consistency
- Reduced straining
- Better overall gut comfort
The study was strong enough to earn a positive opinion from the European Food Safety Authority regarding kiwis’ role in maintaining normal bowel function.
Why kiwis may outperform fibre supplements
Experts say the advantage lies in the type of fibre found in kiwis.
Unlike psyllium, which mainly adds bulk, kiwis contain soluble and prebiotic fibre that nourishes beneficial gut bacteria. This helps improve the gut microbiome—an essential factor in digestion and overall health.
Dr Rajan explains that good digestive health is not just about stool bulk but also about maintaining a healthy balance of gut bacteria.
Immunity benefits of kiwis
Beyond digestion, kiwis may also strengthen the immune system.
Rich in vitamin C, carotenoids, polyphenols and fibre, the fruit supports the body’s natural defences. Studies suggest that regular consumption may:
- Reduce the severity of colds and respiratory infections
- Shorten illness duration
- Support recovery, especially in older adults
Interestingly, while kiwi consumption may not prevent infections entirely, it appears to make symptoms milder and easier to manage.
A simple addition to daily diet
Kiwis are easy to incorporate into meals—whether eaten on their own, added to breakfast bowls or blended into smoothies.
Health experts note that while kiwis offer multiple benefits, they should be part of a balanced diet that includes a variety of fruits, vegetables and nutrients.
The takeaway
Eating two kiwis a day could be a simple, natural way to improve gut health and support immunity. Backed by clinical research, this small dietary change may offer meaningful benefits—particularly for digestion and overall wellbeing.
