The Connection Between Diet and Gout Flares
Gout attacks are a result of hyperuricemia, a condition where excessive uric acid accumulates in the bloodstream. This buildup leads to the formation of urate crystals that settle in the joints, causing intense pain, swelling, and inflammation. Uric acid is a natural byproduct of your body breaking down purines, which are chemical compounds found in many foods. Consuming a diet rich in high-purine foods can contribute significantly to a gout flare-up, especially for those whose bodies cannot efficiently remove excess uric acid.
High-Purine Foods That Cause Gout Flare-ups
Certain foods are well-known to increase uric acid levels and should be limited or avoided, especially during a flare or if you are prone to attacks.
Organ and Game Meats
Organ meats such as liver, kidneys, and sweetbreads are very high in purines and are major gout triggers. Game meats like venison and goose also contain high levels of purines.
Red Meats and Certain Poultry
Beef, lamb, and pork have higher purine content than leaner poultry and should be eaten in moderation. Processed meats like bacon and certain poultry like turkey are also significant purine sources.
Certain Types of Seafood
Some seafood is high in purines and should be limited or avoided. This includes anchovies, sardines, herring, mussels, scallops, and trout. Moderately high-purine seafood like shrimp, lobster, and crab should be consumed in smaller amounts.
Alcohol
Alcohol, particularly beer and spirits, increases gout attack risk. Beer is problematic due to purines from brewer's yeast. All alcohol can reduce the kidneys' ability to excrete uric acid.
Sugary Beverages and High-Fructose Foods
Fructose raises uric acid levels, as its breakdown releases purines. Limit or avoid sweetened drinks like sodas and fruit juices. Packaged sweets and foods with high-fructose corn syrup should also be limited.
Refined Carbohydrates and Yeast Extracts
Refined carbohydrates and foods with yeast extract can contribute to inflammation and raised uric acid. Choose whole grains and check labels for yeast extract.
High-Purine Plant Foods: A Common Misconception
Historically, some high-purine vegetables were advised against. However, studies suggest plant purines do not increase gout risk or uric acid like animal purines. Vegetables are beneficial for a healthy diet and weight management, which is important for controlling gout.
Comparison of Gout Trigger Foods vs. Safer Alternatives
| Food Category | Gout Trigger Foods (Limit or Avoid) | Safer Alternatives (Recommended) |
|---|---|---|
| Protein | Organ meats (liver, kidney), game meats (venison), red meat (beef, pork), specific seafood (sardines, anchovies, scallops). | Low-fat dairy (yogurt, skim milk), eggs, plant-based proteins (tofu, beans, lentils), lean chicken breast. |
| Beverages | Beer, hard liquor, sugary sodas, fruit juices, and drinks with high-fructose corn syrup. | Water (at least 8-16 cups per day), coffee (in moderation), tea, unsweetened tart cherry juice. |
| Carbohydrates | Refined carbs (white bread, pasta), packaged snack foods, sugary breakfast cereals. | Whole grains (oats, brown rice, whole wheat bread), potatoes, fresh fruits and vegetables. |
| Sweeteners | High-fructose corn syrup, honey (high in fructose), large amounts of certain fruits like mango and watermelon. | Cherries, berries, and low-fructose fruits in moderation. |
Beyond Specific Foods: Lifestyle Changes for Gout Management
Beyond diet, lifestyle changes can significantly impact gout.
- Healthier Eating: Diets like DASH or Mediterranean, rich in fruits, vegetables, whole grains, and lean proteins, can lower uric acid.
- Hydration: Drinking plenty of water helps kidneys flush excess uric acid.
- Healthy Weight: Gradual weight loss can reduce uric acid and flare frequency.
Conclusion
Managing gout involves medication and smart dietary choices. Limiting high-purine animal proteins, sugary drinks, and alcohol reduces the uric acid burden. A balanced diet of low-purine vegetables, fruits, whole grains, and low-fat dairy helps stabilize uric acid. Consult your healthcare provider or the Arthritis Foundation for more specific guidance.
