Your body removes uric acid primarily through your kidneys, which handle about 60 to 70% of the job. The remaining 30 to 40% gets broken down by bacteria in your gut. When this system falls behind, uric acid builds up in your blood, a condition called hyperuricemia, defined as levels at or above 6.8 mg/dL. The good news: several dietary changes, lifestyle adjustments, and (when needed) medications can help your body clear uric acid more efficiently.
How Your Body Eliminates Uric Acid
Uric acid is a waste product created when your body breaks down purines, compounds found naturally in your cells and in many foods. Once uric acid enters your bloodstream, your kidneys filter most of it out through urine. Specialized transport proteins in the kidney’s filtering tubes control how much uric acid gets reabsorbed back into the blood versus how much passes through to your bladder. When these transporters reabsorb too much, or when your body produces more uric acid than your kidneys can handle, levels rise.
The gut plays a supporting role. Bacteria in your intestines break down uric acid that gets secreted there, a process called intestinal uricolysis. This means gut health indirectly affects your uric acid balance, though the kidneys remain the primary exit route. Anything that supports healthy kidney function, adequate hydration chief among them, helps your body do what it’s already designed to do.
Cut Back on High-Purine Foods
Since uric acid comes from purine breakdown, reducing purine-heavy foods lowers the raw material your body has to process. The biggest offenders are organ meats like liver, kidney, and sweetbreads. These contain some of the highest purine concentrations of any food and directly raise blood uric acid levels.
Certain seafood also ranks high: anchovies, sardines, shellfish, and codfish. Red meat (beef, lamb, and pork) falls in the moderate category, so smaller portion sizes help rather than complete avoidance. On the other hand, low-fat dairy products actively work in your favor. The proteins in milk, casein and lactalbumin, have a uricosuric effect, meaning they help your kidneys excrete more uric acid. Adding low-fat milk or yogurt to your diet is one of the few dietary moves that both reduces intake and increases output.
Watch Your Fructose Intake
Fructose is unusual among sugars because it directly generates uric acid during metabolism. When your liver processes fructose, it uses up a molecule called ATP for energy. The leftover pieces of that molecule get further broken down into uric acid. This is why drinking sugary beverages, particularly those sweetened with high-fructose corn syrup, causes a rapid spike in blood uric acid levels that other sugars don’t produce.
Sodas, fruit juices with added sugar, and sweetened teas are the most common culprits. Whole fruit contains fructose too, but the fiber slows absorption enough that the effect is much less dramatic. If you’re trying to lower uric acid, cutting sugary drinks is one of the most impactful single changes you can make.
Drink More Water
Your kidneys need adequate fluid to filter uric acid efficiently. Dehydration concentrates uric acid in the blood and reduces the volume of urine available to carry it out. Research shows that exercise-induced sweating and even sauna use can temporarily raise uric acid levels simply through fluid loss. Studies of middle-aged adults found that 72.6% of men and 83.1% of women drink less than 1.5 liters (about 6 cups) of water per day, which is below the threshold for optimal kidney function.
There’s no magic number that works for everyone, but aiming for 2 to 3 liters daily (8 to 12 cups) gives your kidneys plenty of fluid to work with. Spreading intake throughout the day is more effective than drinking large amounts at once. If your urine is consistently pale yellow, you’re likely well hydrated.
Lose Weight Gradually
Carrying extra weight is one of the strongest predictors of high uric acid. In a pilot study of gout patients who followed a moderate calorie-restricted diet for four months, participants lost an average of 7.7 kg (about 17 pounds) and saw their uric acid levels drop by 18%. Among the 12 patients who started with elevated levels, 7 of them (58%) saw their levels return to normal through dietary changes alone.
The key word is “gradually.” Crash diets and extreme fasting can temporarily spike uric acid levels because rapid cell breakdown releases purines. A moderate approach, reducing calories while increasing the proportion of protein and unsaturated fat, produced the best results in that study. Patients with the highest starting uric acid levels saw the biggest drops, which is encouraging if your levels are significantly elevated.
Vitamin C and Tart Cherry
Vitamin C appears to help the kidneys excrete uric acid more effectively. A randomized, placebo-controlled trial found that taking just 500 mg of vitamin C daily for two months reduced serum uric acid by 0.5 mg/dL compared to a placebo group. That’s a modest but meaningful reduction, roughly equivalent to what some dietary patterns achieve. A large prospective study also found that higher vitamin C intake was associated with lower gout risk in men over time.
Tart cherries have generated interest as well. Epidemiological studies suggest that tart cherry consumption can decrease uric acid in both healthy adults and overweight populations, and animal studies show a time-dependent reduction in uric acid levels over a two-week treatment period. The evidence is promising but less robust than for vitamin C. If you enjoy tart cherry juice or dried cherries, they’re a reasonable addition to your strategy, but they’re unlikely to move the needle dramatically on their own.
The DASH Diet Approach
Rather than focusing on individual foods, following an overall dietary pattern may be more sustainable. The DASH diet, originally designed for blood pressure management, emphasizes fruits, vegetables, whole grains, low-fat dairy, and lean protein while limiting red meat, sodium, and sugar. One study found that people following the DASH diet for eight weeks lowered their uric acid by an average of 0.25 mg/dL, with larger reductions in those who started with higher levels.
That reduction might sound small, but it adds up when combined with weight loss, better hydration, and reduced fructose intake. The advantage of DASH over a strict “gout diet” is that it’s a well-rounded eating pattern people actually stick with, rather than a list of restrictions that feels punishing.
When Lifestyle Changes Aren’t Enough
For some people, diet and lifestyle adjustments won’t bring uric acid levels down far enough, particularly if genetics play a strong role in how their kidneys handle uric acid. In these cases, medications fall into two main categories. The first type reduces uric acid production by blocking the enzyme that creates it. The second type, called uricosuric drugs, forces the kidneys to excrete more uric acid by blocking the transport proteins that normally reabsorb it back into the blood.
The American College of Rheumatology recommends medication for people who have had gout flares, not for those with elevated uric acid alone. Their 2020 guidelines conditionally recommend against starting medication for asymptomatic hyperuricemia, meaning high levels without gout symptoms. This is worth knowing if your blood work shows elevated uric acid but you’ve never had a flare: lifestyle measures are the recommended first step.
Realistic Timelines
Diet-driven uric acid reduction doesn’t happen overnight. Most studies showing measurable results use timelines of two to four months. The vitamin C trial saw results at two months. The weight loss study showed an 18% reduction over four months. The DASH diet study measured changes at eight weeks. If you’re making changes and wondering when to recheck your levels, six to eight weeks is a reasonable minimum before expecting to see progress on a blood test.
Consistency matters more than intensity. A sustainable combination of better hydration, reduced sugar and purine intake, gradual weight loss, and possibly a vitamin C supplement will do more over six months than an extreme dietary overhaul you abandon after three weeks.
