Haddock fish scores 48 out of 100 and sits in the moderate band. Middle of the range. Portion size and how often you eat it matter more here.
Penalties took 54.2 points off a starting score of 100, and protective factors added 2.6 back. Every factor is listed in full below.
Scores run 0–100, where higher means more gout-friendly on average. They reflect relative ranking across foods, not a personal risk level. The same food can suit one person and not another, so use the score as a starting point for a conversation with your clinician.

No direct purine measurement has been published for this food, so the score uses the measured median for its category (fish).
We rate this a good confidence estimate.

Scoring rationale
Every factor, in full
Each row shows the points a factor moved, what drove it, and the studies behind its weight.
- -37.3Flare risk
Purine LoadFlare risk
150 mg of purines per 100 g, weighted 1.25x as a seafood source and 1.4x for the typical portion: 263 mg effective.
Evidence: Choi HK 2004, N Engl J Med · Kaneko K 2014, Biol Pharm Bull · Zhang Y 2012, Ann Rheum Dis
- -6.3Long-term
SodiumLong-term
395 mg of sodium per 100 g, scaled 1.4x for the typical portion.
Evidence: FitzGerald JD 2020, Arthritis Care Res
- -3.9Long-term
Calorie DensityLong-term
217 kcal per 100 g, above the 80 kcal energy-density threshold.
Evidence: Aune D 2014, Eur J Nutr
- -3.6Long-term
Saturated FatLong-term
1.73 g of saturated fat per 100 g, scaled 1.4x for the typical portion.
Evidence: Juraschek SP 2016, Arthritis Rheumatol · Yokose C 2021, Curr Opin Rheumatol
- -2Long-term
Nutrient GapsLong-term
Provides meaningful amounts of only 4 of the 5 protective nutrient groups (vitamin C, fiber, omega-3, magnesium and folate).
Evidence: Choi HK 2009, Arch Intern Med · Juraschek SP 2016, Arthritis Rheumatol · Zhang M 2019, Arthritis Rheumatol
- -1.1Long-term
Heme IronLong-term
1.02 mg of iron per 100 g, of which about 40% is heme iron in seafood foods, scaled 1.4x for the typical portion.
Evidence: Li R 2018, Asia Pac J Clin Nutr
- +1.1Flare risk
Omega-3 (EPA+DHA)Flare risk
0.100 g of EPA and DHA omega-3 per 100 g, scaled 1.4x for the typical portion. Omega-3 is linked to fewer recurrent flares.
Evidence: Zhang M 2019, Arthritis Rheumatol

MagnesiumLong-term
21 mg of magnesium per 100 g, scaled 1.4x for the typical portion.
Evidence: Li X 2015, BMJ
