October is National Seafood Month, and for people with gout, seafood carries a mixed reputation. The truth is more useful than the reputation: not all seafood behaves the same way. A plate of baked cod and a plate of dried anchovies are different foods on the purine scale, and the data makes the difference clear. Measured purine values in the FoodCanEat database range from about 76 mg per 100 g for raw scallops to over 1,100 mg per 100 g for dried anchovies. Between those two numbers sit the shrimp, crab, oyster, and fillet options in the seafood case. The task for a person with gout is picking the right category and portion, not giving up seafood.
The low band: white fish and scallops
White fish is the easiest seafood choice for gout. Fresh cod measures 97.9 mg purines per 100 g, and raw scallops are even lower at 76.5 mg. Both sit in the low band, close to the range where low-fat dairy and most vegetables land in the database. That means a cod fillet or a handful of scallops fits comfortably into a low-purine meal pattern without turning the plate into a trigger. White fish also cooperates with portion control: a single fillet is a reasonable serving, and the purine math stays modest even with a generous piece. Baked, grilled, or poached cod with lemon and vegetables is a meal pattern that gout guidelines and dietitians routinely point to. The white fish ranking shows how other white species compare, and most stay well below the red-meat range that drives most flares. For anyone who worries that all fish is off the table, cod is the answer that ends the worry.
The moderate band: crab, clams, oysters, and chum salmon
Between the low band and the high band sits a middle group that works in controlled portions. Red king crab measures 99.5 mg per 100 g, raw clams 110.2 mg, raw oysters 122.0 mg, and chum salmon 124.7 mg. These are not low, but they are not in the high range either. For gout, moderate foods are best treated as occasional rather than daily. A crab salad, a bowl of clam chowder, or a plate of oysters a couple of times a month is a very different exposure than eating them every day. Research on shellfish and gout is mixed, and individual response varies, which is why measured values matter more than general labels. The shellfish ranking lets you compare crab, clams, and oysters side by side before you order. Keep the sides gentle — lemon, light broth, plenty of vegetables — and the meal stays reasonable. Oysters are also a source of zinc, and the purine number simply argues for moderation rather than elimination.
The high band: shrimp, squid, sardines, farmed salmon, and dried fish
The high band is where most of the confusion lives, because several popular items sit here. Farmed shrimp measures 182.4 mg per 100 g and squid 186.8 mg, which lands them moderate-high. Raw sardine measures 210.7 mg, and Atlantic farmed salmon measures 249.9 mg — nearly double the 124.7 mg of chum salmon. The same species can differ widely by form and farming method, which is why the database keeps these entries separate. Dried fish is another category entirely. Drying removes water and concentrates purines: dried whitebait measures 471.5 mg and dried anchovy measures 1,109.0 mg per 100 g, the highest values on this list. Dried anchovies appear as a garnish across many cuisines, and for gout they belong in the same careful category as organ meats. If you use them, treat them as the exception rather than the base of a dish. The sardine and anchovy ranking covers this end of the scale, and the same logic extends to dried or fermented fish products in general.
Picking seafood for a gout meal
The practical rule is straightforward: choose from the low band most of the time, treat the moderate band as occasional, and keep the high band rare. Portion size matters as much as category. Every number above is the reference point for 100 g; a restaurant fillet can be two or three times that, which multiplies the purine load. Splitting a fish dish, ordering the smaller portion, or building the plate mostly from vegetables keeps the total down. Cooking method matters too. Grilling or baking cod is very different from frying the same fish in breading, and a broth-based preparation adds less saturated fat than a butter-heavy sauce. Weight management is one of the better-supported ways to lower urate over time, so choosing lean, low-purine seafood may help twice: fewer purines and a lighter meal. Regular fatty fish intake is associated with cardiovascular benefits in the general population, so the goal is to capture those benefits from the moderate end of the list rather than skipping seafood altogether. Our seafood and gout guide walks through the full framework, including how to read serving sizes and how to order at restaurants. A sensible pattern is low-purine seafood once or twice a week, a moderate shellfish meal now and then, and the high and dried items kept for special occasions in small amounts.
Frequently asked questions
Can people with gout eat seafood at all?
Yes, and the data supports a choose-and-portion approach rather than a blanket ban. Low-purine items like scallops (76.5 mg/100 g) and cod (97.9 mg/100 g) are far from the trigger range, and moderate shellfish such as crab, clams, and oysters can appear occasionally in sensible portions. High items — sardines, dried anchovies, and dried whitebait — are the ones to treat with care. The pattern that shows up repeatedly in research is that total purine intake and individual triggers drive flares, and seafood sits across the whole range, so blanket rules miss the point. If a person knows their own trigger foods, a food diary is a practical way to see which seafood, if any, matters for them. For most people, low-purine seafood a few times a week is fine, and the caution belongs to the moderate and high bands.
Is shrimp high in purines?
Shrimp is moderate-high, not the worst offender but not low. Farmed mixed-species shrimp measures 182.4 mg purines per 100 g in the database, which places it near squid (186.8 mg) and above crab (99.5 mg) and clams (110.2 mg). For gout, that argues for treating shrimp as an occasional food with a modest portion rather than a daily staple. A few shrimp in a stir-fry or on a salad is a much smaller exposure than a shrimp platter. Older guidance sometimes lumped shrimp with the highest-purine seafood, but the measured value sits below sardine (210.7 mg) and far below dried anchovy (1,109.0 mg). The takeaway is portion-based: shrimp is not in the avoid-list range, but it is not a free food either. Choosing shrimp as an accent rather than the center of a plate keeps the exposure small.
Which seafood should people with gout avoid?
The highest values cluster in dried and oily fish. Dried anchovy measures 1,109.0 mg purines per 100 g and dried whitebait 471.5 mg — both extreme, because drying concentrates everything. Raw sardine (210.7 mg) and Atlantic farmed salmon (249.9 mg) are also high, which is why oily fish deserve the same caution as organ meats. Note that the same species can differ by form: chum salmon reads 124.7 mg, roughly half the farmed Atlantic value. The practical list to treat with care is dried anchovies, dried whitebait, sardines, and farmed Atlantic salmon, plus shrimp and squid if portions grow large. For everything else, the low and moderate bands give people with gout plenty of seafood to work with. Choosing fish on the low end and keeping total purines modest may help keep urate in a comfortable range, while reserving the high end for rare occasions.
