Diet Guide
Low Purine Diet
Purines are natural compounds found in many foods. When broken down, they produce uric acid. High uric acid levels can cause gout, uric acid kidney stones, and contribute to kidney disease progression.
Why purines matter
Purines are found naturally in the body and in many foods. When purines are broken down, they produce uric acid as a waste product. Healthy kidneys filter uric acid from the blood and excrete it in urine. When kidney function is reduced — or when uric acid production is too high — uric acid accumulates.
Elevated uric acid (hyperuricemia) can cause gout (painful joint inflammation), uric acid kidney stones, and may directly damage kidney tubules. A low purine diet, combined with adequate hydration, helps lower uric acid levels.
Your nephrologist may also prescribe medications such as allopurinol or febuxostat to reduce uric acid production. Diet and medication work together — neither alone is usually sufficient for patients with significant hyperuricemia.
Lower purine — good choices
• All fruits and fruit juices
• Most vegetables (see exceptions)
• Bread, pasta, rice, cereals
• Eggs
• Low-fat dairy (milk, yogurt, cheese)
• Nuts and peanut butter
• Coffee (may lower uric acid)
• Water and non-sweetened beverages
• Tofu (moderate)
• Chicken and turkey (small portions)
High purine — limit or avoid
• Organ meats (liver, kidney, sweetbreads)
• Red meat (beef, pork, lamb) — limit portions
• Shellfish (shrimp, lobster, crab, scallops)
• Anchovies, sardines, herring, mackerel
• Alcohol (especially beer and spirits)
• Sugary drinks and high-fructose corn syrup
• Gravy and meat broths
• Asparagus, spinach, mushrooms (moderate)
• Dried beans and lentils (moderate)
• Yeast and yeast extracts
Practical tips
Stay well hydrated
Drink 2–3 liters of water daily. Adequate hydration helps the kidneys excrete uric acid and reduces the risk of uric acid stone formation.
Avoid alcohol
Alcohol — especially beer — is high in purines and also impairs uric acid excretion. Even moderate alcohol consumption can trigger gout flares.
Limit sugary drinks
Fructose (found in sodas, fruit juices, and high-fructose corn syrup) stimulates uric acid production. Avoid sweetened beverages.
Choose low-fat dairy
Low-fat dairy products (milk, yogurt) have been shown to lower uric acid levels and reduce gout risk. Include them daily if your phosphorus and potassium levels allow.
Maintain a healthy weight
Obesity is strongly associated with elevated uric acid. Gradual weight loss (not crash dieting, which can temporarily raise uric acid) helps lower levels over time.
