Category Average: 113.4 mg/100g

The average across 4 Fish & Oyster Sauces foods with lab-measured data. Foods below this average are better-than-typical choices within this category.

How to Use This Ranking

The purine ranking is sorted from lowest to highest. Rank #1 is the lowest-purine food in the category. Foods in the top half (above median) should be consumed with more awareness of portion and frequency. The difference between adjacent ranks varies: in some categories, rank #5 and #10 might be only 10 mg apart; in others, the gap can be 100+ mg. Always check the actual milligram value, not just the position. Rankings do not account for fructose or alcohol — use individual food pages for a complete risk assessment.

ACR 2020 Guideline Context

The American College of Rheumatology recommends that gout patients focus on purine awareness rather than complete food group elimination. Within any category, there is a wide purine range. The goal is to shift toward lower-purine choices within categories you already eat, rather than eliminating entire food groups. This ranking helps you identify which specific items to prioritize and which to limit.

Japanese guidelines recommend under 400 mg of total dietary purines per day. Using this ranking, you can estimate how much of budget each food uses per typical serving.

How This Comparison Is Built

Every food in this comparison has been evaluated using a three-factor risk engine that independently assesses purine content, fructose level, and alcohol presence. Purine values come from two primary references — the USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025) and Kaneko et al. (Biol Pharm Bull 37(5):709-721, 2014, PMID: 24553148). Fructose data is sourced from USDA SR28 Food Composition Tables. The verdict system follows ACR 2020 guideline thresholds: Safe (purine <50 mg, fructose <2g, no alcohol), Moderate (purine 50-150 mg or fructose 2-5g), Avoid (purine >150 mg, fructose >5g, or alcohol present). Data quality is labeled T1 (lab-measured), T2 (measured + consensus), or T3 (category estimate) on each food's detail page.

Frequently Asked Questions

Is oyster sauce bad for gout?
Oyster sauce measures moderate in purines — about 134.4 mg/100g in our database — because it is a concentrated oyster extract. Among 4 fish and oyster sauce entries with measured values, levels run from 91.6 to 134.4 mg/100g. In practice a stir-fry uses a tablespoon or two, so the actual purine contribution is small — but heavy, sauce-drenched dishes add up.
Which sauce is lowest: fish sauce or oyster sauce?
Seasoned flying-fish roe sauce measures lowest in our database at about 91.6 mg/100g, with fish sauce around 93.1 mg/100g and oyster sauce highest near 134.4 mg/100g. All are moderate. Soy sauce remains the lower-purine choice (around 45-55 mg/100g in our data), so for everyday seasoning soy sauce is the lighter pick among Asian sauces.
Can I use fish sauce with gout?
in normal cooking amounts. Fish sauce measures about 93.1 mg/100g in our database — moderate — and recipes typically call for a teaspoon or two. Like soy sauce, its bigger issue is sodium, which matters for blood pressure and kidney health. Use it for flavor rather than volume, and balance saucy dishes with plain rice and vegetables.
