Gout is caused by uric acid building up in the blood until it forms needle-like crystals in joints, and the biggest drivers of that buildup are genetics and how your kidneys handle uric acid, not what you ate last night. Diet matters, but less than a century of moralizing suggests: food choices typically move uric acid by only about 1 mg/dL. Understanding what actually causes gout, and what doesn’t, is the difference between effective treatment and years of blame, restriction, and recurring flares. What Actually Causes Gout Uric acid is a normal breakdown product of purines, compounds found in your own cells and in food.

What Causes Gout? Foods to Avoid, Uric Acid, and the Myths a Rheumatologist Wants You to Stop Believing
What Actually Causes Gout
Uric acid is a normal breakdown product of purines, compounds found in your own cells and in food. Trouble starts when blood levels stay above about 6.8 mg/dL, the point where uric acid can crystallize. Sustained elevation comes from:
- Under-excretion (about 90 percent of cases). Most people with gout make normal amounts of uric acid. Their kidneys simply clear less of it, a trait that is substantially genetic. This is why gout runs so strongly in families.
- Chronic kidney disease. Reduced kidney function means reduced uric acid clearance.
- Medications. Diuretics (“water pills”) are the classic culprit; low-dose aspirin, cyclosporine, and some other drugs also raise levels.
- Metabolic conditions. Obesity, insulin resistance, high blood pressure, and metabolic syndrome all impair uric acid handling.
- Overproduction (the minority). Diet contributes here, along with rapid cell turnover states and rare enzyme conditions.
Flares themselves are often set off by triggers that make levels swing: dehydration, a drinking binge, fasting or crash dieting, surgery, illness, or starting uric-acid-lowering therapy without flare prophylaxis.
Foods and Drinks That Genuinely Raise Gout Risk
The evidence is strongest for these, and two of the worst offenders aren’t “purine-rich foods” at all:
- Beer: a double hit, high in purines while alcohol impairs uric acid excretion. Liquor also raises risk; wine appears more modest in moderation.
- Sugary drinks and fructose: soda and sweetened juices raise uric acid through fructose metabolism itself. This one surprises most patients. Soda is a bigger gout problem than steak.
- Organ meats: liver, kidney, sweetbreads, the highest-purine foods there are.
- Certain seafood: anchovies, sardines, herring, mussels, scallops.
- Red meat: beef, lamb, pork in large or frequent portions.
- Crash diets and fasting: rapid weight loss transiently spikes uric acid and can trigger flares.
Foods That Help (or Are Wrongly Blamed)
- Low-fat dairy: consistently associated with lower uric acid and fewer flares.
- Coffee: associated with lower gout risk in multiple large studies.
- Cherries: modest evidence for reduced flare frequency. Reasonable, not miraculous.
- Vitamin C rich foods: mildly uricosuric.
- Purine-rich vegetables (spinach, asparagus, mushrooms, lentils): decades on the “avoid” lists, yet studies show plant purines do not meaningfully raise gout risk. Eat your vegetables and beans.
- Water: steady hydration protects against the concentration swings that trigger flares.
- Gradual weight loss: one of the most effective non-drug levers, lowering uric acid and flare frequency.
The Myths a Rheumatologist Hears Every Week
Myth 1: “Gout means you eat and drink too much.” Gout’s strongest determinants are genes and kidney function. Plenty of teetotal, health-conscious patients have severe gout; plenty of steak-loving beer drinkers never will. The “disease of kings” framing is medically obsolete and keeps people from seeking treatment out of shame.
Myth 2: “I can fix gout with diet alone.” A strict diet typically lowers uric acid by about 1 mg/dL. If your level is 8.5 and the target is below 6, diet won’t close the gap. Diet supports treatment; medication achieves it.
Myth 3: “My uric acid was normal during the flare, so it’s not gout.” Uric acid commonly drops during acute flares. A normal level during an attack rules out nothing. Recheck it weeks later.
Myth 4: “No pain between attacks means gout is gone.” Between flares, crystals continue accumulating silently in joints, the “intercritical” phase, and can erode bone. Advanced imaging shows deposits growing in pain-free joints. Silence isn’t remission.
Myth 5: “Tomatoes, all seafood, and all protein are forbidden.” Blanket lists overshoot the evidence. The consistently guilty parties are alcohol (especially beer), fructose, organ meats, and certain fish. Beyond that, moderation beats elimination.
Myth 6: “Gout is just bad luck with pain, not a real disease.” Untreated gout is associated with kidney disease, kidney stones, cardiovascular risk, and permanent joint damage. Treating it properly is health care, not comfort care.
When Food Advice Isn’t Enough
If you’ve had two or more flares in a year, tophi (crystal lumps under the skin), kidney disease, or a uric acid level far above target, dietary optimization is important but insufficient. That’s the threshold where guidelines call for urate-lowering medication with treat-to-target monitoring. The combination of sensible diet, properly dosed medication, and a doctor who actually titrates to below 6 mg/dL is how gout goes from a recurring ambush to a solved problem.
Frequently Asked Questions
Genetically influenced under-excretion of uric acid by the kidneys, responsible for roughly 90 percent of cases. Diet, alcohol, certain medications, and kidney disease raise risk on top of that foundation, but gout is fundamentally a disorder of uric acid handling, not gluttony.
The strongest evidence supports limiting beer and liquor, sugary drinks and fructose, organ meats, and high-purine seafood such as anchovies, sardines, and mussels. Red meat should be moderated. Purine-rich vegetables and legumes do not need to be avoided.
No. Eggs are low in purines and are a gout-friendly protein source. Low-fat dairy is another protein option associated with lower uric acid levels.
Hydration helps modestly and protects against the concentration swings that can trigger flares, but water alone won’t bring an elevated uric acid to target. Think of it as inexpensive, useful support, not treatment.
Stop Blaming Dinner. See Dr. Dhillon by Video This Week.
If flares keep coming despite your best efforts at the table, the missing piece is usually a treat-to-target plan, not a stricter list of forbidden foods. Dr. Dhillon, a board-certified rheumatologist, sees new patients by secure video visit from your home, usually within the same week, with records reviewed in advance, local lab orders, and direct texting access between appointments. No referral required. Video visits are available to patients located in California, with in-person care in Beverly Hills.
