Salmon is a reasonable choice for people with gout, as long as you keep portions moderate. It falls in the low-to-moderate range for purines (the compounds your body converts into uric acid), and its omega-3 fat content may actually help reduce gout flares over time. The key is how much you eat and how you cook it.
Purine Content in Salmon
Purines are naturally occurring compounds in many foods. When your body breaks them down, it produces uric acid. Too much uric acid leads to the crystal buildup in joints that causes gout pain. Foods with fewer purines produce less uric acid, which is why purine content matters for your diet choices.
Salmon contains roughly 75 to 177 mg of purines per 100 grams, depending on the variety and how it’s measured. Different databases report different values because purine content varies by species, cut, and preparation. Either way, salmon sits well below the 200 mg threshold that marks high-purine seafood. For comparison, here’s how it stacks up against other popular fish:
- Sardines: 133 to 145 mg per 100g
- Anchovies: 109 to 273 mg per 100g
- Trout: 131 to 180 mg per 100g
- Tuna (fresh fillet): 63 to 157 mg per 100g
- Mackerel: 71 mg per 100g
- Mussels: 293 mg per 100g
Salmon lands in a safer zone than sardines, anchovies, trout, and mussels. The American College of Rheumatology advises people with gout to avoid shellfish, organ meats, and red meat, but does not specifically call out salmon. The Mayo Clinic goes further, noting that even people with gout can include small amounts of fish, and uses a 4-ounce serving of roasted salmon as an example in its gout-friendly sample menu.
Omega-3 Fats May Reduce Flares
Salmon is one of the richest dietary sources of omega-3 fatty acids, and these fats appear to work in your favor when it comes to gout. Omega-3s compete with another fatty acid in your body that drives inflammation. When omega-3s win that competition, the inflammatory compounds your body produces are significantly weaker, which can mean less intense and less frequent flares.
A pilot randomized trial presented at the American College of Rheumatology tested this directly. Forty people with gout received either fish oil supplements or no supplement for 24 weeks. The researchers found a strong correlation between higher omega-3 levels in participants’ red blood cells and fewer gout flares. The correlation was striking: for total omega-3, EPA, and DHA individually, each showed a correlation coefficient around -0.75, meaning that as omega-3 levels went up, flare counts went down in a consistent, statistically significant pattern. The supplements also had no negative effect on uric acid levels or body weight.
This doesn’t mean salmon cures gout, but it suggests that the omega-3s you get from eating it could work alongside your other treatments rather than against them.
How You Cook It Matters
A three-year follow-up study of Japanese adults found something surprising: the risk of developing high uric acid levels was linked to eating raw fish (sashimi and sushi) or roasted fish, but not boiled or fried fish. The likely explanation is that boiling leaches purines out of the flesh and into the cooking water. When you poach or simmer salmon and discard the liquid, you’re removing a portion of the purines before eating.
Roasting and grilling concentrate the purines because the moisture evaporates but the purines stay in the fish. Eating salmon raw, as in sushi or sashimi, means you’re getting the full purine load with nothing removed. If you’re managing gout, poaching, steaming, or making a soup where you don’t drink the broth are your best preparation methods. Pan-frying also showed no increased risk in the study, possibly because fat acts as a barrier that changes how purines are retained.
Portion Size and Frequency
The Mayo Clinic’s gout diet guidelines reference a 4-ounce (roughly 115-gram) serving as a reasonable portion. That’s about the size of a deck of cards, which is smaller than a typical restaurant fillet. Sticking to this size keeps your purine intake from a single meal well within a manageable range.
There’s no universally agreed-upon weekly limit for salmon if you have gout, but general guidance for gout-friendly diets suggests limiting total meat and fish intake to 4 to 6 ounces per day. Eating salmon two to three times per week while keeping other high-purine proteins low on those days gives you the omega-3 benefits without overloading your system with purines. On days you eat salmon, balance the rest of your plate with low-purine foods like vegetables, whole grains, eggs, and low-fat dairy.
Fish to Choose and Fish to Skip
Not all seafood carries the same risk. If you enjoy fish and want to keep it in your diet, focus on options under 100 mg of purines per 100 grams. Salmon, mackerel, tuna (especially canned in water), and sole all fall into this friendlier range. Cod sits right around the borderline at 98 mg.
The fish to limit or avoid are those above 200 mg per 100 grams. Anchovies, mussels, and certain small oily fish like sprats top the charts. Shrimp and squid also run high. Shellfish in general is the category the American College of Rheumatology specifically flags, so clams, mussels, and scallops deserve extra caution even though some sit in the moderate range.
If you’re choosing between salmon and a different protein entirely, keep in mind that chicken breast and most plant-based proteins are lower in purines than any fish. But salmon brings cardiovascular and anti-inflammatory benefits that most other proteins don’t, making it worth keeping on your plate in controlled amounts rather than cutting it out completely.
