According to research by the New Zealand Institute of Nutrition (2023), kiwi is rich in vitamin C and potassium, which help neutralize uric acid in the blood and enhance the excretion through urine. This mechanism helps reduce the risk of urate crystallization, the main cause of gout and kidney stones.
Dr. Jonathan Ramsay, urologist at Hammersmith Hospital (UK), said: People with high uric acid levels should take kiwi supplements regularly. This fruit not only has a mild diuretic effect but also helps reduce inflammation and improve blood circulation in the kidneys".
In addition, kiwi contains the enzyme actinidin, a compound that helps break down proteins, aids digestion and reduces the metabolic burden on the kidneys. A kiwi provides about 70 mg of vitamin C, which is almost equivalent to the daily needs of adults.
Experts recommend eating 12 fresh kiwis a day, preferably in the morning or after main meals, for optimal results. However, people with severe chronic kidney disease should consult a doctor before regularly supplementing, because the potassium content in kiwi is quite high.
From a small fruit, kiwi is proving to be of great value in protecting the kidneys and controlling uric acid. Combined with a low-purine diet, adequate water intake and reasonable exercise, kiwi can become a "green Helper" to help maintain sustainable kidney health.
