Bananas are a low-purine food, so they do not promote the production of uric acid like foods rich in purines (red meat, organs, some seafood).
This makes bananas a safe choice in the diet for people at risk of gout. Bananas contain vitamin C, an antioxidant that has been shown to help reduce serine uric acid levels by increasing urate excretion through the kidneys.
gathering clinical evidence and guidelines for gout treatment recommends supplementing fruits rich in vitamin C as part of a balanced diet.
Bananas provide potassium, minerals that help regulate water-salt balance, support permeability pressure and kidney function, which can increase the ability to excrete urate in urine.
At the same time, bananas (especially unripe bananas) contain prebiotics (green bananas rich in resistant starch) that help nourish the intestinal microflora; Recent studies show that microbiological balance plays a role in the metabolism of purines and uric levels, so improving intestinal health can indirectly help reduce uric acid.
These mechanisms are described in an overview of the nutritional benefits of plant-based diets for uric acid and kidney health.
Eating a medium banana (~100-120g) after breakfast or as a snack is a reasonable serving that provides potassium and vitamin C without adding too much concentrated sugar.
Prioritize fresh bananas over juices or added smoothies; juices reduce fiber and may contain concentrated fructose, while high fructose can promote uric acid synthesis. Therefore, avoid sugary fruit drinks.
Combine with a low-purine and high-fiber diet ( curd, whole grains, low-fat milk) to reduce the origin of urate production and increase urate excretion through the kidneys.
People with chronic kidney disease: bananas have a high potassium content, if the kidneys have reduced the ability to excrete potassium, eating a lot of bananas can increase blood potassium, causing danger.
People with moderate to severe kidney disease should consult a nutritionist or doctor before increasing their banana intake.
Fresh fruits such as bananas in moderation are usually safe, but you should avoid using bananas with sugar or as a drink with a lot of sugar.
