Tuna and Gout: Is Fish Safe?
Tuna and Gout: Is Fish Safe?
Quick Answer
Tuna contains very high purines (approximately 366 mg per 100g), among the highest of all foods. Tuna should be avoided or limited to once monthly in minimal amounts. Fish like tuna are strongly associated with gout flare-ups.
Purine Content in Tuna
| Serving Size | Purine Content (mg) | % of Daily Limit |
|---|---|---|
| 100g (canned in water) | 366 mg | 37% |
| 150g (small can) | 549 mg | 55% |
Why Tuna Is Bad for Gout
Tuna ranks among the highest purine foods, making it one of the worst choices for gout sufferers. Even a small canned tuna serving provides over half a daily purine budget. Research specifically identifies tuna and other high-purine fish as strong triggers for gout flares.
If you eat tuna, limit to once monthly in minimal portions (2-3 ounces) and increase hydration substantially.
