Salmon vs Tuna: which has more purines?
Tuna is higher: 211.2 mg of purines per 100 g against 147 mg for Salmon. That is a difference of 64.2 mg per 100 g, and it puts the two in different bands.
147mg per 100 g
Fairly high · 75–150 mg
A 150 g serving works out to 221 mg. Across 9 measured preparations, 88–259.8 mg.
211.2mg per 100 g
Very high · 200–300 mg
A 150 g serving works out to 317 mg. Across 5 measured preparations, 142–492.9 mg.
Salmon vs Tuna purine content, per serving
Per 100 g is how the databases publish, and it is not how anyone eats. At the default servings above, Salmon contributes 221 mg and Tuna contributes 317 mg. The gap between two foods matters much less than how much of either one ends up on the plate — which is the argument for weighing the portion rather than memorising a chart.
It is also why the single number at the top of a purine chart misleads. Tuna at 211.2 mg per 100 g and Salmon at 147 mg swap places the moment one portion is half the size of the other, and portions of salmon and tuna are rarely the same weight in practice.
Why the two numbers differ
Purine content tracks cell density and the tissue's metabolic activity, which is why organ meats sit far above muscle meats and why drying anything moves it up the scale. Tuna measures 64.2 mg per 100 g above Salmon. Whether that is a difference worth acting on depends on portion size and on how often either appears in a week.
Every measurement behind the two salmon and tuna figures
The headline numbers are medians across the preparations each database measured, and the spread underneath them is the part most charts hide. Here are the highest and lowest measured preparations of each, with the database that produced them.

Why other charts rank salmon and tuna differently
Because the band lines move between countries. The same milligram figure is called different things depending on whose scheme you read, which is most of the reason two purine charts can disagree about a food without either being wrong. Here is what each published scheme calls these two:
Salmon, 147 mg
| Scheme | This food is | Band covers |
|---|---|---|
| NHC dietary guidelineChina | Fairly high | 75–150 mg |
| Common three-tier chartEnglish-language | Moderate | 50–150 mg |
| Gout treatment guidelineJapan | Unnamed in the guideline | 100–200 mg |

- Common three-tier chart — The split used across English-language dietetic handouts and purine charts A widely repeated convention rather than a scheme published by one named body.
- Gout treatment guideline — Guideline for the Management of Hyperuricaemia and Gout, Japanese Society of Gout and Uric & Nucleic Acids, as published by the Gout and Uric Acid Foundation of Japan The guideline names four bands and leaves 100–200 mg unnamed; Japanese charts commonly fill that gap with an informal 'moderate'.

Lower-purine alternatives to Tuna
If the reason for the comparison is to bring a meal down rather than to settle which of two foods wins, these measure lower than both and sit in the same part of the shop:
A purine number is not a risk score
Worth saying on any page that ranks two foods against each other. Beer measures low and is the drink most consistently linked with gout attacks, because alcohol slows how quickly the kidneys clear urate. Sugary soft drinks contain essentially no purines and are associated with substantially higher risk, because fructose prompts the body to manufacture uric acid after the drink.
So this comparison answers exactly what it says: which of these two foods delivers more purines per 100 g. More on the gap between the number and the risk.

- Dietary Guideline for Adults with Hyperuricaemia and Gout (2024 Edition)
Every preparation measured for each food, with its own citation, is on the two food pages: Salmon and Tuna. You can also compare any two of the 372 foods or add up a whole day.

Common questions
Which has more purines, salmon or tuna?
Tuna is higher: 211.2 mg of purines per 100 g against 147 mg for Salmon. That is a difference of 64.2 mg per 100 g, and it puts the two in different bands.
Is salmon a safe swap for tuna with gout?
On purines alone it is a step down: 64.2 mg less per 100 g. Whether that matters for you is a different question — purine content is one property of a food, and it does not account for alcohol slowing urate clearance or fructose prompting the body to make its own. Your own diet is a question for your doctor or dietitian.
Do these numbers change with cooking?
Substantially. Boiling moves purines into water that is then poured away, while grilling and drying remove water and concentrate what is left. Both foods here list every preparation measured, with the source for each — the range within one food is often wider than the gap between the two.
