Ketchup and gout
Verdict: Ketchup is low in purines — you can eat it regularly as part of a gout-friendly diet.
Ketchup is a tomato-based condiment that is very low in purines, containing just 7.8 mg per 100 g. This makes it a safe choice for people managing gout, whether during a flare or as part of daily maintenance. Since gout sufferers typically aim to stay under 400 mg of purines per day, ketchup contributes almost nothing to this total. You can use ketchup freely as a flavoring on burgers, fries, or other foods without worrying about triggering symptoms. A practical tip: remember that while ketchup itself is gout-friendly, some foods it accompanies—like processed meats or organ meats—may be higher in purines, so focus on what you're dipping rather than the ketchup. Staying well hydrated and maintaining overall portion control of your meal remains important for managing gout, but ketchup is not a concern.

🔴 During a flare
Ketchup stays a reasonable choice, but reduce portions and prioritise hydration (2 L/day).
🟢 Daily maintenance
