AUG Index — World first
The first food indices designed for gout, kidney stones and weight
Our 3 composite weighted indices cross-reference up to 22 nutritional parameters per food, drawn from 20 scientific databases. A score from 0 to 100 to instantly know what to eat — and what to avoid.
2,281 foods analyzed • 20 scientific databases • 3 exclusive composite indices
Living with high uric acid or gout flare-ups?
You no longer know what to eat. Every meal feels like a gamble. Online information is contradictory, and your doctor doesn't always have time to provide a detailed eating plan.
- You avoid foods without knowing if it's necessary
- You want reliable answers, not conflicting opinions
- You need a practical tool, not generic advice
Scientific method
Weighted indices, not just a food list
Unlike standard purine tables, our AUG indices cross-reference up to 22 parameters per food: purines, fructose, oxalates, PRAL, glycemic index, sodium, alcohol, fiber, calcium, and more. Each parameter is weighted according to peer-reviewed scientific publications.
- 3 composite weighted indices (gout, stones, weight)
- Up to 22 cross-referenced parameters per index
- 20 scientific databases analyzed
- Normalized 0-to-100 score with color coding

composite weighted indices
Three connected risks. One tool to manage them all.
Uric acid is not just about gout. It sits at the heart of three very common health problems — that make each other worse. Our 3 indices evaluate all three simultaneously for every food, in real time.
🦶
Gout
Hyperuricemia causes crystals in the joints — painful flares, often in the big toe. Each food gets a Gout Index that factors in purines, fructose and anti-inflammatory effects. A low score means a safe food.
🫘
Kidney stones
Excess uric acid promotes stone formation. The Stone Index incorporates oxalates, citrates, urinary pH and calorie density. Many foods that are gout-friendly (spinach, tomatoes) still deserve attention for the kidneys.
⚖️
Weight
Excess weight is the leading modifiable risk factor for gout. The Weight Index evaluates satiety, glycemic response and calorie density. Building a filling meal without aggravating uric acid — that's the goal.
Understand to make better choices
🔬
Uric acid and purines: how it works
Making the right food choices starts with understanding the mechanism. Here's how uric acid forms in your body and why certain foods cause problems.
Where does uric acid come from?
Uric acid is a natural waste product your body creates when it breaks down purines. Purines are found in many foods (meat, organ meats, seafood, some legumes) and also in your own cells. Under normal conditions, your kidneys filter and eliminate uric acid through urine.
What happens when levels are too high?
When uric acid rises above a certain threshold — called hyperuricemia (above 7 mg/dL in men, 6 mg/dL in women) — it can form tiny needle-shaped crystals that settle in your joints. This is what triggers gout flare-ups: intense pain, swelling, redness, often in the big toe. (source: StatPearls, NCBI)
Why diet is the key
Roughly one third of uric acid comes directly from food. By identifying high-purine foods and limiting them, you take direct action on your levels. For example, 100 g of anchovies contain 411 mg of purines (very high), while 100 g of rice contains only 15 mg (very low). Our database gives you this data for every food.
📈
AUG Weight Index: glycemic index at the heart of the score
Most people with gout only watch their purine intake. Yet the AUG Weight Index integrates glycemic index as a central parameter — here's why it's essential.
The link between insulin and uric acid
High-GI foods (white bread, potatoes, sweets) cause rapid blood sugar spikes. Your pancreas responds with a burst of insulin. That insulin directly slows the kidneys' ability to clear uric acid. The result: even without eating high-purine foods, a high-GI meal raises your uric acid.
The fructose trap
Fructose — abundant in sodas, industrial juices and ultra-processed foods — poses a double threat. Not only does it have a moderate GI, but the liver converts it directly into purines during metabolism. A single can of soda per day can increase the risk of a gout flare-up by 45% in men and 74% in women.
AUG Weight Index: a 13-parameter formula
The AUG Weight Index goes beyond glycemic index. It also incorporates calorie density, satiety and glycemic load into a 13-parameter formula. That's what sets it apart from a standard diet table: a single score from 0 to 100 that tells you, for every food, whether it helps or hinders your weight — and therefore, indirectly, your uric acid.

What the database reveals about everyday foods
This is how the database actually analyses these foods. Each entry reveals the 3 AUG indices — gout, kidney stones, weight — calculated from 22 scientific parameters. This is exactly what you get for every one of the 2,281 foods.
