White radish is a winter-spring radish, with a high water content (over 90%), low in energy, very low in purines and rich in vitamin C, potassium, soluble fiber and glucosinolate compounds.
According to nutritional overviews, a diet rich in low-purine and high-hydration foods helps dilute uric acid in the blood, while increasing kidney excretion.
Vitamin C in white radish has been proven by many epidemiological studies to be related to reducing serum uric acid levels.
Các phân tích từ National Institutes of Health (NIH) cho thấy, vitamin C có thể tăng bài tiết axit uric qua nước tiểu bằng cách cải thiện chức năng lọc của thận và giảm tái hấp thu urat tại ống thận.
White radish affects the process of controlling uric acid through three main mechanisms.
First, increase uric acid excretion through the kidneys.
The high water content and natural potassium in white radish help promote mild urination, supporting the kidneys to excrete uric acid more effectively.
Second, reduce inflammation associated with increased uric acid.
Antioxidant compounds such as vitamin C and polyphenols in white radish help reduce oxidative stress, a factor contributing to worsening inflammatory reactions caused by urate crystals.
Many studies show that inflammation and oxidation control are key to reducing the frequency of acute gout attacks and protecting long-term kidney function.
Third, support the digestive system and purine metabolism.
The fiber in white radish helps improve the gut microbiome, supports the elimination of nitrogen and purine products through the digestive tract, indirectly reducing the burden on the liver and kidneys.
WHO and many international health organizations agree that uric acid control needs a comprehensive approach, in which a diet rich in vegetables, low in purines, limiting alcohol and red meat is the foundation.
Radish soup should be cooked with fish or tofu, limiting salt and saturated fat.
Boil or steam lightly, avoid stir-frying with a lot of grease.
Combine with green vegetables and fruits rich in vitamin C to increase the effectiveness of urate excretion.
Avoid eating too salty or sour foods because high sodium can reduce uric acid secretion.
People with chronic kidney disease, severe gout or taking uric acid-lowering drugs should consult a doctor before changing their diet.
