Corn & Sweet Green Peppers: Purine Ranking (Lowest to Highest)

Evidence-based comparison — data from USDA+ODS-NIH PURINE DATABASE Release 2 (March 2025)

Lowest Purine

#1Corn11.7 mg/100g
#2corn, raw11.8 mg/100g
#3cayenne pepper powder19.9 mg/100g

Highest Purine

#5cayenne pepper powder19.9 mg/100g

#3Green pepper69.2 mg/100g

Category Average: 36.3 mg/100g/100g

The average across 5 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 corn low in purines?
Yes — corn measures 11.7 to 11.8 mg per 100g in our database, comfortably in the Safe range. Corn is a staple grain-vegetable that fits easily into gout-friendly plates, whether on the cob, in salads or as a side. The caution points sit with what accompanies it: butter and salt on corn, or fried tortilla preparations.
Why do green peppers have more purine than corn?
Sweet green peppers measure 69.1 to 69.2 mg per 100g — higher than corn, and higher than many vegetables — but still far below the 150 mg threshold we use for Avoid-level foods. Plant purines also appear to carry lower gout risk than animal purines in cohort research, so a moderate vegetable number is not the same warning sign a meat number is.
Are cayenne and hot pepper powders different?
Cayenne pepper powder measures 19.9 mg per 100g in our data — low, and you would rarely eat 100g of it anyway. Spices contribute negligible purines in real portions. The gout-relevant part of spicy dishes is almost always the company the peppers keep: chili with ground beef, buffalo wings, or the beer beside them.
