Octopus scores 26 out of 100 and sits in the caution band. Ranks toward the higher-risk end. Many people choose to keep portions smaller and less frequent.
Penalties took 77.3 points off a starting score of 100, and protective factors added 3.4 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.

Where the purine figure comes from
No direct purine measurement has been published for this food, so the score uses the measured median for its category (shellfish).
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.
- -41.4Flare risk
Purine LoadFlare risk
175 mg of purines per 100 g, weighted 1.25x as a seafood source and 1.4x for the typical portion: 295 mg effective.
Evidence: Choi HK 2004, N Engl J Med · Kaneko K 2014, Biol Pharm Bull · Zhang Y 2012, Ann Rheum Dis
- -15Flare risk
Category: ShellfishFlare risk
High purine seafood with RR 1.51 (Choi 2004); worse than finfish.
Evidence: Choi HK 2004, N Engl J Med · Choi HK 2008, BMJ · Zhang Y 2006, Am J Med
- -8Long-term
SodiumLong-term
518 mg of sodium per 100 g, scaled 1.4x for the typical portion.
Evidence: FitzGerald JD 2020, Arthritis Care Res
- -5Long-term
Heme IronLong-term
4.92 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
- -4.2Long-term
Calorie DensityLong-term
226 kcal per 100 g, above the 80 kcal energy-density threshold.
Evidence: Aune D 2014, Eur J Nutr
- -3.7Long-term
Saturated FatLong-term
1.84 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
- +1.3Flare risk
Omega-3 (EPA+DHA)Flare risk
0.120 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
- +0.9Long-term
MagnesiumLong-term
28 mg of magnesium per 100 g, scaled 1.4x for the typical portion.
Evidence: Li X 2015, BMJ
- +0.4Long-term
Vitamin CLong-term
3 mg of vitamin C per 100 g, scaled 1.4x for the typical portion. Vitamin C helps the kidneys excrete urate.
Evidence: Choi HK 2009, Arch Intern Med · Juraschek SP 2011, Arthritis Care Res
- +0.4Long-term
FiberLong-term
0.5 g of dietary fiber per 100 g, scaled 1.4x for the typical portion.
Evidence: Juraschek SP 2016, Arthritis Rheumatol
- +0.4Long-term
FolateLong-term
33 µg of folate per 100 g, scaled 1.4x for the typical portion.
