Understanding Purines and Uric Acid
Purines are natural compounds found in the body and in many foods. Their breakdown produces uric acid. High uric acid levels (hyperuricemia) can lead to gout attacks due to crystal formation in joints. Managing dietary purine intake is important for gout.
The Purine Content of Tomatoes
Fresh tomatoes are low in purines. A 100g serving typically contains 4 to 11mg of purines, significantly less than high-purine foods. Processed tomato products are also generally low in purines, though it's important to check for high-fructose corn syrup, a known gout trigger. Moderate tomato consumption is usually safe based on purine content.
The "tomato and gout" paradox
Despite being low in purines, some gout sufferers report tomatoes as a trigger. This could be due to other compounds like glutamate, which might temporarily increase uric acid in some individuals. This highlights that factors beyond purine content can influence gout.
Tomatoes vs. High-Purine Foods: A Comparison
This table shows how tomatoes compare in purine content to other foods:
| Food Category | Purine Content per 100g | Example | Typical Gout Impact | Citation(s) |
|---|---|---|---|---|
| Low-Purine | 0-25mg | Tomatoes, Cherries, Skim Milk | Generally safe for most | |
| Moderate-Purine | 25-150mg | Chicken Breast, Salmon | Can be eaten in moderation | |
| High-Purine | >150mg | Liver, Anchovies, Beer | Should be limited or avoided |
How to Determine if Tomatoes Trigger Your Gout
Individual responses vary, making personal monitoring essential.
The food journal method
Keeping a food journal to track intake and symptoms can help identify patterns.
Consulting a healthcare provider
Discussing suspected triggers with a doctor or dietitian provides personalized advice and guidance.
Benefits of Tomatoes for Overall Health
Tomatoes offer health benefits, including anti-inflammatory antioxidants. They are rich in lycopene, vitamins C and K1, and potassium. For those without sensitivity, these benefits make tomatoes a valuable dietary addition.
Gout-Friendly Dietary Alternatives
If tomatoes are a trigger, consider alternatives like basil pesto, roasted bell peppers, or pureed carrots for flavor. Anti-inflammatory fruits like cherries and blueberries are also good options.
Conclusion: The Final Verdict on Tomatoes and Purines
While is tomato high in purines is a common question, the answer is no. Fresh tomatoes are low in purines. Reports of them triggering gout are primarily anecdotal, likely due to individual sensitivity to other compounds rather than high purine content. Personal monitoring through a food journal and consulting a healthcare professional are the best ways to determine if tomatoes are a trigger for you. For most, tomatoes can be a healthy part of a gout-friendly diet.

Keypoints
- Low Purine Content: Fresh tomatoes are generally low in purines, containing only a small amount per 100g serving.
- Individual Trigger: Despite low purines, a small percentage of gout patients report tomatoes as a personal trigger for flares.
- Glutamate Connection: The amino acid glutamate in tomatoes, rather than purines, may be responsible for temporarily increasing uric acid levels in some individuals.
- Personal Monitoring is Key: The most effective way to determine if tomatoes are a trigger for you is to keep a food journal and consult a healthcare professional.
- Nutrient-Dense: Tomatoes offer significant health benefits, including anti-inflammatory antioxidants like lycopene, and are rich in vitamins C and K.
