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.
