About the Platform

What UricAcid.online is, who it is for, and how the platform works.

Yes. The full purine database, personalised meal plans, uric acid tracker, symptom journal, and clinical guides are open to every visitor — no account, no subscription, no paywall. Our commitment is permanent.
No. Everything works without registration. Your inputs (uric acid level, food searches, AI queries) live in your browser session only. Close the tab and nothing is stored on any server.
A small team of clinical nutritionists, medical researchers, and digital health professionals — including specialists in metabolic nutrition, rheumatology, and renal dietetics. Read our team profiles on the About page.
We update purine values, clinical guides, and dietary protocols monthly as new peer-reviewed research is published. The blog publishes new evidence-based articles roughly twice a month.

Diet & Purines

How dietary purines affect uric acid and how a low-purine diet works in practice.

Purine values are sourced primarily from USDA nutritional data and peer-reviewed clinical research. Each food is classified Safe / Moderate / Avoid against established thresholds (under 50 mg, 50–150 mg, and over 150 mg of purines per 100 g). We update the database monthly as new research is published.
Most rheumatology guidelines recommend keeping total daily purine intake below 400 mg for patients in remission, and below 200 mg during an active flare. Our diet plan calibrates this target to your current serum uric acid level.
Organ meats (liver, kidney, sweetbreads), anchovies, sardines, mackerel, shellfish, game meats, beer, and high-fructose drinks are the most potent triggers. Each of these can raise serum uric acid by 0.5–1.5 mg/dL within hours.
Yes — multiple randomised studies have shown that 1–2 servings of tart cherries (or 1 oz of cherry juice concentrate) daily reduces serum uric acid and gout flare frequency. The mechanism appears to involve anthocyanins enhancing renal uric acid excretion.
Yes, in moderation. White-meat chicken (skinless), salmon, tilapia, and most freshwater fish fall in the Moderate range (50–150 mg purines per 100 g). Limit portions to 100–150 g per day and avoid the more potent triggers like anchovies, sardines, and mackerel.
Multiple large epidemiological studies have shown that regular coffee drinkers have significantly lower serum uric acid levels. The mechanism involves inhibition of xanthine oxidase — the same enzyme allopurinol targets. 2–4 cups daily is generally considered safe and potentially protective.

Symptoms & Flares

How to recognise, manage, and prevent gout flares and other uric-acid related symptoms.

Most patients describe sudden, severe, burning pain in a single joint — most commonly the big toe — that escalates over 6 to 12 hours. The joint becomes red, intensely hot, and so swollen that even a bedsheet feels unbearable. Attacks typically subside within 7 to 10 days but recur if uric acid stays elevated.
Uric acid crystallises more readily at lower temperatures, and body temperature drops during sleep. Cortisol — which naturally suppresses inflammation — also reaches its lowest point overnight. Together this makes the 2–6 am window the peak period for acute flares.
Rest the affected joint, apply ice in 20-minute intervals, drink 2–3 litres of water to flush uric acid, and avoid all high-purine foods until the flare resolves. If your physician has prescribed colchicine or NSAIDs, take them at the first sign of pain. Seek emergency care for sudden severe joint pain with fever, which can indicate infection rather than gout.
Yes, if uric acid remains elevated for years. Repeated crystal deposits cause permanent joint erosion (chronic tophaceous gout) and visible chalky nodules called tophi. Sustained reduction of serum uric acid below 6.0 mg/dL can dissolve tophi over 1–3 years and halts further damage.

Uric Acid Levels

How to interpret blood test results and clinical targets.

Above 6.8 mg/dL is the saturation threshold where urate crystals begin to form. The clinical target for gout patients is to keep serum uric acid below 6.0 mg/dL — and below 5.0 mg/dL if tophi are present. Levels above 9.0 mg/dL carry a high risk of tophaceous gout and kidney damage.
In most patients, a structured low-purine diet plus 2–3 litres of daily water can lower serum uric acid by 1.0–2.0 mg/dL within 4 to 8 weeks. The exact drop depends on baseline level, kidney function, and how strictly the diet is followed.
After starting a low-purine diet, re-test every 4–8 weeks until you reach the safe zone. Once stable below 6.0 mg/dL for 6 months, twice-yearly testing is generally enough. During an active flare or after a medication change, your physician may request more frequent monitoring.
Yes. Sustained hyperuricemia is linked to uric acid kidney stones and contributes to chronic kidney disease. Urate crystals can also deposit directly in renal tissue (urate nephropathy) over years of untreated disease. Adequate hydration and a low-purine diet are the primary preventive tools.

Using the Tools

How to use the diet plan, food list, AI assistant, and tracker.

Yes. Enter your current serum uric acid level on the Diet Plan page, and the protocol calibrates daily purine targets, meal portions, and hydration goals to that baseline. Active-flare protocols and remission protocols differ meaningfully.
The assistant runs on a server-side AI model. Your question is passed through our secure backend (your Gemini API key never touches the browser) and the response is grounded in peer-reviewed nutrition research and uric-acid clinical guidelines. Sessions are not stored on our servers.
Yes — saved foods and uric acid logs are kept in your browser's local storage. They persist between visits on the same device but are never sent to a server. Clearing your browser storage removes them; there is no account to recover.
We index every cooking variation, regional dish, and branded product we can find purine values for. This covers everything from raw foods to common takeaways. If you cannot find a food, contact us and we will add it to the next monthly update.

Medical & Privacy

How this platform relates to your medical care and how your data is handled.

Yes — dietary management complements urate-lowering therapy (allopurinol, febuxostat, etc.) and is recommended by every major rheumatology guideline. Always discuss any major dietary change with your physician, especially if you are on medication.
No — and we will never claim otherwise. This is an educational and nutritional support platform. Your physician is the only person who can diagnose gout, prescribe medication, and interpret your specific clinical picture. Use our tools to inform your conversations with them.
Your uric acid logs, food searches, and AI prompts never leave your browser — there is no server database storing personal health information. The only data we receive is what you choose to send through the contact form, which is encrypted in transit and never shared with advertisers.
No. We do not sell user data and we do not share it with advertisers, pharmaceutical companies, or supplement brands. We display contextual Google AdSense ads on some pages, but those run on Google's standard terms — they do not have access to anything you type into our tools.
