Cooked tomatoes are low in purines and generally safe for gout, though some individuals report sensitivity.
Tomatoes are botanically a fruit but used as a vegetable, and they are naturally low in purines, making them a safe staple for most people with gout. Cooking tomatoes—whether stewed, roasted, or simmered into sauces—does not meaningfully change their purine load, but it does concentrate flavors and reduce vitamin C slightly while boosting the bioavailability of lycopene, an antioxidant with anti-inflammatory properties.
A 2015 New Zealand study of people with gout found that tomatoes were among the foods some patients linked to flare-ups, and the research suggested glutamic acid and other compounds in tomatoes may raise serum urate in a subset of susceptible individuals. This does not mean tomatoes are harmful for everyone; most gout patients tolerate them well, but if you notice a pattern of attacks after eating tomato-heavy meals, it is worth limiting them.
Overall, cooked tomatoes are a reasonable part of a gout-friendly diet for most people, but personal response can vary, so observe how your body reacts.
