Is Tilapia Bad for Gout? Why It's Not a Low-Purine Fish
USDA's newest analysis puts tilapia at about 185 mg of purines per 100 g, in the high band, not low. How much fits a gout diet and what to eat instead.
TL;DR
- A 2024 USDA analysis puts tilapia at about 185 mg of purines per 100 g raw, in the high band. A typical 4-ounce fillet carries about 210 mg.
- Many gout lists still call tilapia a low-purine fish, based on figures of around 75–90 mg. The newest US data doesn’t support that.
- Tilapia also has very little omega-3. It can still fit between flares in modest portions, but it’s no longer a “free” fish.
Tilapia isn’t the low-purine fish it’s often made out to be. USDA’s latest lab analysis puts it at about 185 mg of purines per 100 g, in the high band and roughly double the figure on many gout food lists.
That doesn’t make tilapia forbidden. It means treating it like other high-purine fish: a sensible portion, not every day, and not during a flare.
How Many Purines Are in Tilapia?
The USDA and ODS-NIH Database for the Purine Content of Foods (Release 2, 2025) has one entry for tilapia: USDA’s own 2024 analysis of raw farmed tilapia, at about 185 mg of purines per 100 g. Farmed tilapia is what almost every store and restaurant sells, so this is the most relevant number for most readers.
| Tilapia portion (raw weight) | Purines |
|---|---|
| 100 g | ~185 mg |
| 3 oz (85 g) | ~155 mg |
| 4 oz (113 g) | ~210 mg |
| 1 average fillet (about 116 g) | ~215 mg |
| 6 oz (170 g) | ~315 mg |
The average fillet weight is from USDA FoodData Central. Our charts use four bands: low (under 50 mg per 100 g), moderate (50–100), high (100–200) and very high (over 200). Tilapia sits in the upper half of the high band.
The figures are for raw fish. Baking or grilling drives off water, so a gram of cooked tilapia holds more purines than a gram of raw, but the fillet keeps roughly the same total.
Why Do Some Sites Call Tilapia Low-Purine?
Search for tilapia and gout and you’ll find figures of around 75–90 mg per 100 g, often with tilapia near the top of a “best fish for gout” list. Those numbers don’t appear in the USDA purine database. Its only tilapia value is the 2024 analysis at about 185 mg.
Purine figures for the same fish can differ by lab, method and sample, so some spread is normal. But a gap this size changes the advice. At 185 mg, tilapia belongs with trout and fresh tuna, not with the lower-purine white fish. Until other modern analyses say otherwise, it makes sense to go with the newest US data on the fish most people actually buy.
How Does Tilapia Compare With Other Fish?
| Fish (raw) | Purines per 100 g | Per 4 oz (113 g) | Band |
|---|---|---|---|
| Salmon, farmed Atlantic | 250 mg | ~283 mg | Very high |
| Catfish, farmed | 205 mg | ~232 mg | Very high |
| Tilapia, farmed | 185 mg | ~209 mg | High |
| Trout, rainbow | 180 mg | ~203 mg | High |
| Flounder | 115 mg | ~130 mg | High |
| Canned salmon | 110 mg | ~124 mg | High |
| Cod | 105 mg | ~119 mg | High |
| Sea bass | 105 mg | ~119 mg | High |
Tilapia now sits much closer to trout than to cod. A 4-ounce tilapia fillet carries about 90 mg more purines than the same piece of cod.
The other gap is omega-3. USDA FoodData Central lists raw tilapia at about 0.1 g of EPA plus DHA per 100 g, compared with about 0.7 g in farmed rainbow trout and 2.0 g in farmed Atlantic salmon. With tilapia you get the purines of a mid-range fish without much of the omega-3 that makes oily fish worth eating.
Does Tilapia’s Low Omega-3 Matter for Gout?
It may. A 2023 analysis of 12,505 US adults in the NHANES survey split seafood into omega-3-poor types, a group that included tilapia, catfish, cod, shrimp and oysters, and omega-3-rich types such as salmon, trout, sardines and herring. Each extra ounce a day of omega-3-poor seafood was linked to 8.7% higher odds of gout. Omega-3-rich seafood showed no association.
That study is a one-time snapshot, so it can’t show that tilapia causes gout. But it fits with a 2019 study of 724 people with gout, in which eating two or more servings of omega-3-rich fish in the previous 48 hours was linked to 26% lower odds of a flare, after accounting for total purine intake. Tilapia wasn’t one of the fish in that group.
Two other points round out the picture. A 2012 study that followed 633 people with gout for a year found that the biggest two-day purine intakes were linked to nearly five times the odds of a recurrent attack, with animal purines carrying more risk than plant ones. And the American College of Rheumatology’s 2020 guideline conditionally recommends limiting purine intake for people with gout “regardless of disease activity.”
Mercury isn’t the concern here: tilapia is on the FDA’s “Best Choices” list for fish low in mercury. The issue is purines per bite, with little omega-3 to show for them.
How Much Tilapia Is Reasonable?
There’s no official limit, so this is a practical starting point:
- Portion: 3 to 4 ounces raw, about 155–210 mg of purines. An average fillet runs a little over 4 ounces, so a whole one is at the top of that range.
- Frequency: once or twice a week between flares, not as your everyday “safe” fish. Rotate with lower-purine options.
- One high-purine food that day: if tilapia is dinner, skip the shrimp or the deli-meat lunch.
- Build the plate low: rice, potatoes, vegetables and low-fat dairy all sit in the low purine band.
- Drink water, not beer. The ACR guideline also advises limiting alcohol.
If you track meals, an app like Urica can estimate the purines in a tilapia dinner from a photo, so the switch from “low” to “high” doesn’t catch you out.
Tilapia During a Flare vs. Between Flares
During a flare, skip tilapia for a few days along with other high-purine fish and meat, and skip alcohol. Eggs, low-fat dairy and tofu are gentler protein choices. The priority is treatment: the ACR guideline strongly recommends colchicine, NSAIDs or glucocorticoids as first-line options, so start the plan your doctor gave you early. Our guide on how to stop a gout flare fast covers the rest.
Between flares, a 3- to 4-ounce portion with vegetables and a starch is fine for many people. What changes with the new numbers is the frequency: tilapia five nights a week adds up to far more purines than most gout food lists suggest.
How to Cook Tilapia for Gout
- Bake, grill or pan-sear it with lemon, garlic, herbs and olive oil. These methods don’t add purines, but they don’t remove any either.
- Poach or steam it when you’re being cautious. Purines are water-soluble. A 2019 PeerJ study found that boiling moved purines out of marine fish and into the cooking liquid. Tilapia wasn’t tested, so treat that as a general principle, and discard the liquid.
- Fish tacos: tortillas, cabbage slaw, tomato salsa and avocado are all low in purines. Grilled beats battered, and a squeeze of lime beats a sugary sauce.
- Breaded or fried: the coating adds few purines, but deep-frying adds fat and calories, and fried fish often comes with beer.
- Skip sweet glazes. The ACR guideline also advises limiting high-fructose corn syrup, common in bottled sauces.
Better Swaps for Tilapia
| If you want | Try | Purines per 100 g | Why it works |
|---|---|---|---|
| A mild white fillet | Cod | 105 mg | About 40% fewer purines |
| A mild fillet with some omega-3 | Sea bass | 105 mg | About 0.6 g of omega-3 per 100 g |
| A thin, flaky fillet | Flounder | 115 mg | Fewer purines, cooks just as fast |
| A cheap, convenient protein | Canned salmon | 110 mg (90–135) | About 1 g of omega-3 |
| A meatless taco night | Tofu or eggs | 25 / ~0 mg | Low band |
Trout (180 mg) is not a real purine swap, and catfish (205 mg) is a step up. See our purine content in seafood chart for the full list.
The Bottom Line
Tilapia isn’t a low-purine fish. USDA’s 2024 analysis puts it at about 185 mg per 100 g, in the high band, and it has very little omega-3. It can still fit a gout diet between flares: keep portions to 3–4 ounces, eat it once or twice a week rather than daily, make it the only high-purine food of the day, and skip it during a flare. For a mild white fish with fewer purines, cod and sea bass are the better everyday picks.

Frequently Asked Questions
Is tilapia a low-purine fish?
Not by the newest data. A 2024 USDA analysis of farmed tilapia measured about 185 mg of purines per 100 g, which is in the high band (100–200 mg). Many gout lists still show tilapia at around 75–90 mg and call it low-purine, but those figures don't appear in the USDA purine database, whose only tilapia entry is that 2024 analysis. Treat tilapia like other high-purine fish: modest portions, not every day.
Is tilapia better than salmon for gout?
It's somewhat lower in purines, about 185 mg per 100 g versus about 250 mg for US farmed Atlantic salmon, but it has almost no omega-3: about 0.1 g per 100 g versus 2.0 g. In a large US survey analysis, omega-3-poor seafood, tilapia included, was linked to higher odds of gout while omega-3-rich seafood was not. If you want a lower-purine white fish, cod or sea bass is a better pick.
Are fish tacos OK if I have gout?
Usually, in sensible amounts. Two tacos with about 3 ounces of tilapia between them carry roughly 155 mg of purines, and tortillas, cabbage slaw, salsa and avocado are all low in purines. Grilled fish is lighter than battered, and water or a non-alcoholic drink is a better pairing than beer. For a lower-purine taco, use cod or sea bass instead.
Can I eat tilapia during a gout flare?
It's better to skip it for a few days. At about 185 mg per 100 g, tilapia is a high-purine fish, and a 2012 study linked big purine days to higher odds of recurrent attacks. Eggs, low-fat dairy and tofu are lower-purine proteins while a flare settles. Start the treatment your doctor prescribed early, and drink plenty of water unless you've been told to limit fluids.
