Roma tomato and gout
Verdict: Roma tomato is low in purines — you can eat it regularly as part of a gout-friendly diet.
Roma tomatoes are a low-purine vegetable, containing just 5 mg of purines per 100 g in their raw form. This makes them a safe choice for most people managing gout, whether you're in the middle of a flare or following a daily maintenance plan. The key to including tomatoes in your diet is portion control and preparation method—boiling reduces the purine content to 2.3 mg per 100 g, making it an even better option. A reasonable serving is about one medium tomato (roughly 150 g) as part of a meal, which keeps your total purine intake well below the 400 mg daily guideline recommended during maintenance phases. Remember to drink plenty of water throughout the day, as hydration helps your kidneys process uric acid more effectively. Roma tomatoes are versatile and nutritious, so you can confidently enjoy them in salads, soups, or cooked dishes without worrying about triggering a flare.
