Is canned tuna high in purines?
In short: Smart Gout Care estimates ≈ 140 mg of purines in a typical 85 g serving of canned tuna (≈ 160 mg per 100 g), with no added sugar. That is more purines per 100 g than 98% of the 2,045 dishes in the app, and the app rates a serving Moderate load.
| Typical serving | 85 g |
|---|---|
| Purines per serving | ≈ 140 mg |
| Purines per 100 g | ≈ 160 mg |
| Added sugar per serving | 0 g |

About canned tuna
Canned tuna; fish with high purine content and no sugar.
What about smaller or larger portions?
In the app you can set the portion to small, medium or large. The purine estimate scales with the weight:
| Portion | Weight | Purines |
|---|---|---|
| Small | 68 g | ≈ 110 mg |
| Medium (typical) | 85 g | ≈ 140 mg |
| Large | 111 g | ≈ 180 mg |
What does the load badge mean?
The badge compares one typical portion with the daily reference amounts set in the app. A portion is estimated to use a third to two thirds of a day's purine or added-sugar reference. It is a rough guide to the size of a portion's share, not a rule about what to eat.
Where do these numbers come from?
These are Smart Gout Care's own estimates for a typical serving of Canned Tuna, the same figures the app shows for this dish. They are rounded on purpose: published laboratory tables often disagree for the same food, sometimes by two times or more, depending on the sample, the species and the method. For measured values and their sources, see Purines in Fish and Seafood: Lower and Higher Choices.
