Key Insights
Among the 6 foods in this intersection, 6 (100%) are rated Safe — providing a meaningful number of low-risk options that satisfy both 'Safe Foods' and 'Shellfish' criteria.
The average purine content across the 3 foods with data is 31 mg/100g — within the low-purine range, which suggests many options here may fit a gout-aware diet.
Our purine data is sourced from the USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025) and the Kaneko et al. (2014) comprehensive food purine survey covering 270 foodstuffs. Fructose data comes from USDA SR28 food composition tables. Verdict ratings follow a multi-dimensional engine evaluating purine, fructose, and alcohol risk simultaneously.
Frequently Asked Questions
What does it mean when a food is both 'Safe Foods' and 'Shellfish'?
It means the food meets two criteria simultaneously — it belongs to both the 'Safe Foods' and 'Shellfish' categories. Of all foods in our database, 6 items satisfy this dual condition. Instead of checking two separate lists, this page gives you one focused view of the overlap.
How many 'Safe Foods' × 'Shellfish' foods are gout-safe?
6 of the 6 foods (100%) in this intersection are rated Safe for gout. An additional 0 are Moderate and 0 are Avoid. Browse the food list below — Safe items are marked with 🟢, Moderate with 🟡, and Avoid with 🔴.
Should gout patients pay attention to this combination?
Yes — evaluating foods through two lenses (here, 'Safe Foods' and 'Shellfish') gives a clearer risk picture than either filter alone. The 6 foods in this overlap vary considerably in purine and fructose levels. Checking individual entries below helps pinpoint usable vs. high-risk options.
Why use two tags instead of just one?
A single tag like 'Safe Foods' may include hundreds of foods with widely varying safety. Adding the 'Shellfish' filter narrows the results to 6 items where both conditions are true, giving a more targeted and actionable list. This is especially useful when managing multiple dietary constraints simultaneously — a common scenario for gout patients who also need to monitor fructose, alcohol, or specific food categories.
How This Analysis Works
Each food in this intersection is evaluated using a multi-dimensional risk engine that considers three independent gout triggers:
- Purine content (mg per 100g) — The primary driver of uric acid production. Data from USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025) and Kaneko et al. Biol Pharm Bull 37(5):709-721, 2014.
- Fructose content (g per 100g) — Raises uric acid independently of purines through hepatic ATP depletion. Data from USDA SR28.
- Alcohol content — Blocks renal uric acid excretion and accelerates purine breakdown.
A food rated Safe means purine is under 50 mg/100g and fructose under 2g/100g with no alcohol. Moderate indicates purine 50-150 mg/100g or fructose 2-5g/100g. Avoid means purine above 150 mg/100g, fructose above 5g/100g, or presence of alcohol.
All purine values are lab-measured unless marked T3 (category-level estimate). Cross-reference individual food pages for detailed source information.
