Is Duck Bad for Gout? Purines, Portions and Duck Fat
Duck has about 138 mg of purines per 100 g, close to chicken, though it hasn't been lab-tested for the USDA database. Portions, duck fat, liver and swaps.
TL;DR
- Duck is in the high purine band at about 138 mg per 100 g, roughly the same as chicken thigh (about 140). That figure comes from older tables; duck hasn’t been measured for the USDA database.
- A 4-ounce (113 g) portion is roughly 156 mg. Between flares, that’s reasonable as an occasional main. Skip duck during a flare.
- Duck fat isn’t a purine problem, but duck liver and foie gras are organ meat, and whole-duck feasts are where portions balloon.
Duck is a high-purine meat, but not an unusually high one. At about 138 mg per 100 g it sits alongside chicken thigh and lamb, so a normal portion now and then is reasonable between flares for most people.
What makes duck tricky is how it’s served: a whole roast bird, a confit leg, a foie gras starter, or a crispy skin that makes it easy to keep eating.
How Many Purines Are in Duck?
| Duck meat (raw weight) | Purines |
|---|---|
| 100 g | ~138 mg |
| 3 oz (85 g) | ~117 mg |
| 4 oz (113 g) | ~156 mg |
| 6 oz (170 g) | ~235 mg |
Our bands are low (under 50 mg per 100 g), moderate (50–100), high (100–200) and very high (over 200). Duck lands in the lower half of the high band.
One caveat up front: duck isn’t in the USDA and ODS-NIH Database for the Purine Content of Foods, which collects the lab analyses that meet its quality criteria. The 138 figure comes from older purine tables, as do those for wild duck (about 150) and goose (about 165). Use them to compare foods, not as exact counts. Our purine content in meat chart covers the other meats.
Is Duck Worse Than Chicken or Turkey?
| Meat (raw) | Purines per 100 g | Band | Lab data |
|---|---|---|---|
| Goose | ~165 mg | High | Not in the database |
| Chicken breast, skinless | ~160 mg | High | 4 analyses |
| Wild duck | ~150 mg | High | Not in the database |
| Chicken thigh | ~140 mg | High | 1 analysis (65 samples) |
| Duck | ~138 mg | High | Not in the database |
| Chicken drumstick | ~135 mg | High | 1 analysis (25 samples) |
| Lamb | ~130 mg | High | 1 analysis |
| Beef, typical muscle cut | ~105 mg (75–190) | High | 18 analyses |
| Ground turkey | ~95 mg | Moderate | 2 analyses |
Two things stand out. First, duck is in the same range as chicken, so swapping one for the other won’t cut purines much. Second, poultry isn’t automatically the low-purine meat. Skinless chicken breast measures about 160 mg per 100 g, and analyses range from about 130 to 290 depending on the sample. More in is chicken bad for gout and is turkey bad for gout.
The American College of Rheumatology’s 2020 guideline conditionally recommends limiting purine intake for people with gout, regardless of disease activity. It doesn’t single out any one meat, and neither should you: the total on your plate is what counts.
Does Duck Skin or Duck Fat Matter?
Purines are concentrated in lean tissue rather than fat. Butter, for example, measures close to zero in the USDA database. USDA’s analyses of ground beef show the same pattern: the fattier the meat, the fewer purines per 100 g. Regular 80/20 ground beef measures about 160 mg, while 93% lean measures about 190.
So rendered duck fat adds calories, not purines, and duck-fat potatoes are a low-purine side (potatoes are about 5 mg per 100 g). Skin-on duck likely carries somewhat fewer purines per 100 g than lean breast meat, but far more calories.
That still matters for gout, because the ACR guideline conditionally recommends a weight-loss program for people with gout who are overweight. Crispy skin in moderation is fine; a plate of it most weeks is a weight problem, not a purine one.
Duck Liver, Foie Gras and Giblets
These are organ meat, and organ meat is where duck gets riskier.
- Duck liver: no lab data. The bird liver with the most data, chicken liver, measures about 245 mg per 100 g across three analyses, in the very high band.
- Foie gras: fattened duck or goose liver, with almost no lab data on purines. Portions are small, which helps, but treat it as liver.
- Giblets and giblet gravy: the heart, gizzard and liver add organ meat to the plate. Skip the giblet gravy if you’re being careful.
Our guide to liver and organ meats has the numbers and the reasons behind them.
How Much Duck Is Reasonable?
- Portion: 3 to 4 ounces of meat, about 117–156 mg of purines.
- Frequency: an occasional main rather than a weekly staple.
- Whole roast duck: it’s meant to be shared. Carve your portion onto the plate rather than picking at the carcass.
- Duck confit: a single leg is a full portion on its own, and it’s cured with plenty of salt.
- Peking duck: a few slices in pancakes is modest. Go easy on the hoisin, which is sweet.
- One high-purine food per meal: duck or a foie gras starter, not both, and no shellfish course alongside.
- Sweet sauces: orange and cherry sauces are low in purines but often sugary. The ACR guideline also conditionally recommends limiting high-fructose corn syrup.
Purines add up over a day or two, and heavy stretches are linked to flares. In a 2012 study of 633 people with gout, the highest fifth of purine intake over two days carried about 4.8 times the odds of a recurrent attack compared with the lowest fifth. Purines from animal foods carried more risk than those from plants.

Duck During a Flare vs. Between Flares
During a flare, skip duck, and definitely any liver or foie gras, until it settles. Start the treatment your doctor prescribed; the ACR guideline strongly recommends colchicine, NSAIDs or glucocorticoids as first-line options. The Arthritis Foundation suggests at least 8 glasses of nonalcoholic fluids a day, and 16 during a flare, with plain water as the best choice, unless you’ve been told to limit fluids.
Between flares, a 3- to 4-ounce portion of duck now and then is reasonable, with low-purine sides such as rice, potatoes and vegetables. If you take a urate-lowering medicine, the ACR guideline strongly recommends keeping serum urate below 6 mg/dL and still suggests limiting purines alongside it.
Better Swaps for Duck
| Instead of | Try | Why it helps |
|---|---|---|
| Duck breast in a stir-fry or larb | Ground turkey | ~95 vs. ~138 mg per 100 g |
| Foie gras or duck liver pâté starter | A salad or vegetable soup | Keeps organ meat off the menu |
| Half a roast duck | A 4-ounce portion, extra vegetables and potatoes | Caps the purines |
| Duck on most weekends | Eggs, tofu or cheese-based dinners some nights | Eggs ~0, tofu ~25, cheese ~10 mg per 100 g |
| Swapping duck for chicken “for gout” | Keep the duck, shrink the portion | Chicken thigh ~140, breast ~160: no real saving |
The Bottom Line
Duck is a high-purine meat for gout, at about 138 mg per 100 g, in the same range as chicken and lamb. That figure comes from older tables, since duck hasn’t been measured for the USDA database. A 3- to 4-ounce portion now and then is reasonable between flares, especially with low-purine sides. Duck fat adds calories rather than purines, but duck liver, foie gras and giblets are organ meat and deserve more caution. Skip duck during a flare, and share the whole bird.

Frequently Asked Questions
Is duck worse than chicken for gout?
Not really. Duck is listed at about 138 mg of purines per 100 g, and lab analyses put chicken thigh at about 140 and skinless chicken breast at about 160. Duck hasn't been measured for the USDA database, so the comparison is rough, but switching from duck to chicken won't meaningfully cut purines. The size of the portion matters much more than which bird it came from.
Is duck fat bad for gout?
Not because of purines. Purines sit mostly in lean tissue, and pure fats such as butter measure close to zero. Potatoes roasted in duck fat are a low-purine side. The catch is calories: duck fat and duck skin are very rich, and the American College of Rheumatology conditionally recommends a weight-loss program for people with gout who are overweight.
Is foie gras bad for gout?
Treat it like other liver. Foie gras is the fattened liver of a duck or goose, and there's almost no lab data on its purine content. The bird liver with the most data, chicken liver, measures about 245 mg per 100 g, in the very high band. Foie gras is usually served in small slices, which helps, but skip it during a flare and don't pair it with a duck main.
Is Peking duck OK for gout?
In a normal portion, yes, between flares. A few slices of duck in pancakes with cucumber and scallions is a modest amount of meat. The things to watch are how many pancakes you go back for, the sweet hoisin sauce, and whether the meal also includes other high-purine dishes. Share it, and fill the rest of the plate with rice and vegetables.
