Tomato and gout

Low in purines 4.6 mg / 100 g

Verdict: Tomato is low in purines — you can eat it regularly as part of a gout-friendly diet.

Tomatoes are a excellent choice for anyone managing gout. With just 4.6 mg of purines per 100 g in their raw form, they sit firmly in the low-purine category and can be enjoyed regularly without concern. This means tomatoes won't significantly contribute to uric acid buildup in your body, even during your daily maintenance phase when you're aiming to stay under 400 mg of purines per day. The good news extends to different preparations: boiled tomatoes contain even less at 2.3 mg per 100 g, while steamed versions have 2.9 mg. The only variant worth noting is roasted tomatoes, which contain 7.8 mg per 100 g—still low, but slightly higher due to concentration during cooking. You can confidently add tomatoes to salads, sauces, and cooked dishes. A practical tip: enjoy tomatoes as part of a balanced meal and remember to stay well hydrated, as proper fluid intake helps your kidneys process uric acid more efficiently.

Frequently asked questions

Can I eat tomatoes during a gout flare?

Yes, tomatoes are safe to eat even during a flare because of their very low purine content. They won't worsen your symptoms and can be part of your meals while you're managing an acute episode.

Does cooking tomatoes change how safe they are for gout?

Most cooking methods keep tomatoes gout-friendly. Boiling actually reduces purines to 2.3 mg per 100 g. Roasting is the exception, raising the content to 7.8 mg per 100 g, but this is still considered low and acceptable for gout management.

How much tomato can I safely eat?

You can eat tomatoes freely as part of your regular diet since they're low in purines. Focus instead on overall daily purine intake from all foods combined, aiming to stay under 400 mg per day during maintenance.
