Watermelon and gout
Verdict: Watermelon is low in purines — you can eat it regularly as part of a gout-friendly diet.
Watermelon is a refreshing summer fruit with a very low purine content of just 7 mg per 100 g, making it a safe choice for people managing gout. Because watermelon is naturally low in purines, it won't contribute significantly to uric acid buildup in your body. What makes watermelon particularly helpful during gout management is its high water content—roughly 92% water—which supports kidney function and may help flush uric acid from your system. You can enjoy watermelon freely as part of your daily diet without worrying about triggering a flare. A practical tip: aim for a reasonable portion of 150–200 g (about a medium slice), which delivers hydration and nutrients without excess calories. Even if you eat a larger serving, the purine load remains negligible, so watermelon is one of the fruits you can confidently include during both flare prevention and periods of maintenance.

🔴 During a flare
