Tomato paste is purine-poor but concentrated; most people with gout tolerate it, though some report tomatoes as a flare trigger.
Tomato paste is cooked-down tomatoes — roughly four to six times the solids of the fresh fruit. Its purine content is genuinely low (on the order of 10–20 mg per 100 g), so it contributes very little to the purine load that drives urate production, unlike red meat, shellfish, and beer [1]. A normal recipe portion is only 1–2 tablespoons (15–35 g).
Tomatoes are an oddity in gout. They are low in purines, yet in a New Zealand survey roughly one in five people with gout named tomatoes as a trigger for their flares, and the same research found a modest link between tomato intake and higher serum urate [2]. The mechanism is unproven — glutamate and umami intensity, acidity, and lycopene have all been proposed. Treat this as a personal-sensitivity issue, not a proven hazard.
