Staying hydrated, limiting certain foods and alcohol, and keeping uric acid levels below 6 mg/dL are the most effective ways to prevent gout flare-ups. Most flares happen when uric acid crystals build up in your joints over time, so prevention comes down to reducing how much uric acid your body produces, helping it flush more out, and avoiding the specific triggers that tip you into an attack.
Keep Uric Acid Below the Crystal Threshold
Uric acid forms needle-like crystals in your joints when blood levels stay above about 6.8 mg/dL. Both the American College of Rheumatology and the UK’s NICE guidelines recommend a target below 6 mg/dL for people with gout. If you have visible lumps of crystals under the skin (tophi) or frequent flares despite treatment, a lower target of 5 mg/dL is more appropriate because you have more crystal deposits to dissolve.
If you’re having two or more flares a year, have tophi, or show joint damage on imaging, guidelines strongly recommend starting a urate-lowering medication. Even with fewer than two flares a year, medication is worth discussing with your doctor if you’ve had more than one attack. The goal isn’t just to treat each flare as it comes but to keep uric acid consistently low enough that crystals gradually dissolve and new ones stop forming.
One important detail: when you first start urate-lowering medication, flares can temporarily increase as crystals begin to break apart. A low-dose anti-inflammatory taken alongside the medication for the first six months significantly reduces these startup flares.
Drink Enough Water Every Day
Water helps your kidneys flush uric acid, and the effect on flare prevention is surprisingly large. In a study of gout patients, those who drank five to eight glasses of water per day had 43% fewer attacks compared to those who drank one glass or less. Drinking more than eight glasses a day (roughly a half-gallon) pushed that reduction to 48%. Even two to four glasses showed a modest benefit, though it wasn’t statistically significant. The takeaway: aim for at least five 8-ounce glasses daily, and more if you can manage it.
Foods That Raise Your Risk
Purines are compounds in certain foods that your body breaks down into uric acid. The highest-purine foods, and the ones most worth avoiding, are organ meats like liver, kidney, and sweetbreads. Red meat (beef, lamb, pork) and certain seafood, particularly anchovies, sardines, shellfish, and codfish, also raise uric acid levels and are best eaten in smaller portions or less often.
Sugary foods and drinks deserve just as much attention. Fructose, especially from high-fructose corn syrup, triggers a chain reaction inside your cells: processing fructose burns through your cells’ energy currency (ATP), and the breakdown products feed directly into uric acid production. This means sodas, sweetened cereals, some canned soups, and baked goods made with high-fructose corn syrup can spike your uric acid even though they contain no purines at all.
Foods That Lower Your Risk
Low-fat dairy products are one of the clearest dietary winners for gout prevention. Skim milk contains compounds, including orotic acid, that help your body excrete uric acid through the kidneys. Certain milk proteins also appear to reduce joint inflammation and the frequency of flares. A daily serving or two of low-fat milk or yogurt is a straightforward addition to your routine.
Tart cherries have solid evidence behind them. In a study of 633 people with gout, consuming cherries was associated with a 35% lower risk of flares. The benefit likely comes from their high concentration of anthocyanins, pigments with anti-inflammatory properties. Tart cherry juice concentrate, about 30 mL diluted in water daily, is the most practical form. Fresh or frozen tart cherries work too.
How Different Types of Alcohol Compare
All alcohol raises gout risk, but the type and amount matter. Beer is a double threat because it contains both alcohol and purines. Drinking two to four beers raised flare risk by 75%, and four to six beers more than doubled it. Hard liquor at two to four drinks increased risk by 67%. Wine, often assumed to be safer, actually showed the sharpest jump at moderate intake: just one to two glasses raised flare risk by 138% in one case-crossover study, though at higher amounts the statistical significance dropped off.
The practical message is that no type of alcohol gets a free pass during a period when you’re trying to prevent flares. If you do drink, keeping it to one serving and staying well-hydrated can help limit the impact.
Coffee and Vitamin C
Coffee appears to lower uric acid levels independently of caffeine, likely through other compounds that affect how your kidneys handle uric acid. A meta-analysis found that one or more cups per day was associated with a reduced risk of gout, with a stronger effect at higher intake. Men saw benefit at one to three cups daily, while women needed four to six cups for a comparable reduction. If you already drink coffee, this is a reason not to stop. If you don’t, it’s not a strong enough effect to start purely for gout prevention.
Vitamin C at 500 mg per day reduced uric acid by about 0.5 mg/dL in a two-month randomized trial. That’s a modest but real drop, roughly equivalent to the effect of a small dietary change. A 500 mg supplement is inexpensive and low-risk for most people, making it a reasonable add-on alongside other strategies. Higher doses don’t appear to be necessary.
Weight and Overall Lifestyle
Carrying extra weight is one of the strongest risk factors for gout because larger bodies tend to produce more uric acid and excrete less of it. Losing weight gradually lowers uric acid levels over time. The key word is gradually: crash diets and fasting can temporarily spike uric acid as your body breaks down tissue rapidly, potentially triggering the very flare you’re trying to avoid. A steady loss of one to two pounds per week through sustainable dietary changes is the safer approach.
Regular physical activity helps with weight management and may independently improve how your body processes uric acid, though the evidence for exercise alone is less clear-cut than for diet and medication. Dehydration during exercise is a real flare trigger, so drinking extra water before and after workouts matters more for you than for the average person.
Putting It All Together
Prevention works best as a combination. No single change eliminates flares on its own, but stacking several together produces meaningful results. Drinking enough water, cutting back on high-purine foods and fructose, adding low-fat dairy and tart cherries, moderating alcohol, and maintaining a healthy weight form the lifestyle foundation. For people with frequent flares or high uric acid levels, medication to keep uric acid below 6 mg/dL is the most reliable way to stop attacks long-term. The goal is to get uric acid low enough that existing crystals dissolve and new ones never form, which for many people means flares eventually stop entirely.
