Uric Acid in Foods: Complete Table and Database
Comprehensive reference table of uric acid potential in foods. Learn how purines in food convert to uric acid and which foods have the greatest impact.
If you have searched for “uric acid in foods,” you are looking for information that is important but slightly misframed. Foods do not contain uric acid in meaningful amounts. What they contain are purines, nitrogen-based compounds found in the DNA and RNA of every living cell. Your body converts these dietary purines into uric acid through a series of enzymatic reactions. Understanding this conversion process, and which foods produce the most uric acid, is essential for managing gout effectively.
This reference, part of our purine database, provides a comprehensive table of foods ranked by the purines in a typical serving, explains the conversion process, and puts dietary uric acid in context with the other factors that influence your blood levels.
From Purines to Uric Acid: The Conversion Process
When you eat food containing purines, the following sequence occurs:
- Digestion breaks down food proteins and nucleic acids, releasing purine bases (adenine, guanine, hypoxanthine, xanthine)
- Absorption transports purines through the intestinal wall into the bloodstream
- Metabolism in the liver converts purines through enzymatic steps
- Xanthine oxidase catalyzes the final conversion of hypoxanthine to xanthine, then xanthine to uric acid
- Excretion removes uric acid through the kidneys (about 70%) and intestines (about 30%)
The conversion pathway:
| Step | Conversion | Enzyme |
|---|---|---|
| 1 | Adenosine (from adenine nucleotides) → inosine | Adenosine deaminase |
| 2 | Inosine → hypoxanthine | Purine nucleoside phosphorylase |
| 3 | Hypoxanthine → xanthine | Xanthine oxidase |
| 4 | Xanthine → uric acid (end product in humans) | Xanthine oxidase |
Alternatively:
| Step | Conversion | Enzyme |
|---|---|---|
| 1 | Guanine → xanthine | Guanine deaminase |
| 2 | Xanthine → uric acid (end product in humans) | Xanthine oxidase |
Humans, unlike most other mammals, lack the enzyme uricase that would break down uric acid further into allantoin. This is why uric acid accumulates in our blood in the first place.
Uric Acid Yield by Food Category
Not all purines are converted to uric acid at the same rate. The bioavailability of purines (how much is actually absorbed and converted) varies by food source, and purines from animal foods are more strongly linked to gout than purines from plants. There is no reliable measurement of how much of each food’s purine ends up as uric acid, so this table shows typical purine content alongside what studies have found about each food group and gout.
| Food Category | Typical Purines (mg/100g) | Gout Association |
|---|---|---|
| Organ meats | 145–285 (livers 210–285) | Strong |
| Red meat | About 70–245 | Moderate-strong |
| Seafood (oily fish) | About 140–355 | Strong |
| Poultry | About 95–195 | Moderate |
| Seafood (whitefish) | About 105–205 | Moderate |
| Beer/yeast | Beer about 10 per 100 mL; yeast products very high | Very strong |
| Legumes | About 10–65 (cooked or canned) | None detected |
| Vegetables | Mostly under 50; spinach about 110 | None detected |
| Dairy | Under 15 | Protective |
| Grains | About 5–40 (cooked) | None detected |
This table illustrates why purine content alone does not tell the full story. Spinach, at about 110mg per 100g, has not been linked to gout, while meat and seafood with similar or higher values have.
Complete Uric Acid Potential Table
The following table ranks common foods by the purines in a typical serving: purine content multiplied by serving weight, using raw weight for meat and fish. That is the part of uric acid production you control through diet. Plant purines appear to count for less than animal purines, so read the vegetable, legume, and grain rows with that in mind. Values are the median of published analyses in the USDA & ODS-NIH Purine Database (2025). Foods marked † aren’t in that database; their values come from older tables. Foods marked * rest on one or two analyses that came in far below older tables (herring about 290, scallops about 220, beef kidney about 450 per 100g), so caution still applies.

‡ Beer’s uric acid impact exceeds what purine content alone would predict because it contains guanosine (efficiently converted purine) and alcohol impairs uric acid excretion.
Low Uric Acid Potential (Under 50mg purines per serving)
| Food | Purine (mg/100g) | Typical Serving | Purines per Serving | Category |
|---|---|---|---|---|
| Bacon | 100 (60–140) | 45g (3 slices, raw weight) | 45mg | Meat |
| Mushrooms | 45 | 70g (1 cup) | 30mg | Vegetable |
| Asparagus | 35 | 90g (6 spears) | 30mg | Vegetable |
| Tofu | 25 (20–30) | 115g | 30mg | Legume |
| Apple † | 10 | 180g (1 medium) | 18mg | Fruit |

| Yogurt | 5 | 170g (6 oz) | 9mg | Dairy |
| Potato | 5 | 150g (1 medium) | 8mg | Vegetable |
| Banana | 5 | 120g (1 medium) | 6mg | Fruit |

| Egg (whole) | <3 | 50g (1 egg) | <1mg | Protein |
| Lentils (cooked) | Not measured cooked | 100g (1/2 cup) | Likely low to moderate | Legume |
Cooked lentils haven’t been analyzed; dried lentils measure about 220mg per 100g before cooking, and cooked or canned, drained beans measure about 10 to 25mg per 100g.
The contrast is still dramatic. A tin of sardines carries about 340mg of purines, while an egg or a cup of milk carries under 1mg.
Non-Purine Factors That Raise Uric Acid
Foods can raise your blood uric acid levels without containing any purines at all. This is a critical concept that purine-only tables miss entirely. For a side-by-side comparison of purine values, see our purine food chart.
| Food/Substance | Purine Content | Mechanism for Raising Uric Acid | Impact |
|---|---|---|---|
| Regular soda (HFCS) | 0 mg | Fructose depletes ATP, producing uric acid | High |
| Fruit juice | <3 mg | Concentrated fructose | High |
| Honey | <3 mg | 40.9% fructose | High |
| Agave nectar | 5 mg | 55.6% fructose | Very high |
| Beer | About 10 mg per 100 mL | Alcohol impairs excretion + guanosine | Very high |
| Wine | <3 mg | Alcohol impairs excretion | Moderate |
| Spirits | <3 mg | Alcohol impairs excretion | Moderate |
| High GI foods | Variable | Insulin resistance impairs excretion | Moderate (chronic) |
A can of regular soda with zero purines can raise uric acid levels soon after you drink it, through fructose-driven ATP depletion. This underscores why purine content alone is an incomplete measure of a food’s impact on uric acid.
Where Does Your Uric Acid Come From?
To put dietary uric acid in proper context:
| Source | Share of Total Uric Acid | Modifiable by Diet? |
|---|---|---|
| Made by the body (cell turnover and new purine synthesis) | About two thirds | Limited (weight loss helps) |
| Dietary purines | About one third | Yes |
Even if you eliminated all dietary purines (which is neither possible nor advisable), you would only address about one third of your uric acid production. The remaining two thirds come from your body’s normal metabolic processes.
This is why the majority of gout management is about excretion, not just intake. For a detailed look at how this works, see uric acid excretion. For most gout patients, who are classified as under-excreters, improving the kidneys’ ability to clear uric acid is more impactful than further dietary restriction.
Factors That Affect Uric Acid Excretion
Since excretion is the bottleneck for most gout patients, these factors deserve as much attention as dietary purine content:
| Factor | Effect on Excretion | Practical Action |
|---|---|---|
| Hydration | Dehydration reduces kidney clearance | Drink adequate water daily |
| Alcohol | Lactate competes for excretion | Moderate or avoid, especially beer |
| Fructose | Organic acids compete for excretion | Reduce sugary drinks, HFCS |
| Insulin resistance | Increases URAT1 reabsorption | Low GI diet, weight management |
| Medications (diuretics) | Impair uric acid excretion | Discuss alternatives with doctor |
| Kidney function | Primary excretion organ | Monitor with regular bloodwork |
| Gut microbiome | 30% of excretion is intestinal | Fiber, fermented foods |
| High blood pressure | Associated with impaired excretion | Treatment may improve clearance |
| Body weight | Obesity impairs excretion and increases production | Gradual weight loss |
Using the Uric Acid Table Effectively
Rather than using this table to set a daily uric acid budget, consider it a tool for understanding relative food impacts. The difference between a tin of sardines (about 340mg of purines) and a cup of yogurt (about 9mg) is meaningful. The difference between a chicken thigh (about 160mg) and a chicken breast (about 185mg) is not.
Focus your attention on the extremes:
- Organ meats, small oily fish and shellfish, and large portions of some everyday meats and fish (such as US pork chops and salmon) carry the most purines per serving
- Fructose sources raise uric acid through a separate pathway
- Alcohol impairs excretion regardless of purine content
- Vegetables, dairy, eggs, and grains produce minimal uric acid, even the few vegetables that are relatively high in purines
Comprehensive Tracking
Uric acid management is multifactorial. Tracking only purine intake gives you one third of the dietary picture and ignores excretion entirely. Urica tracks purine content, fructose intake, hydration, and other metabolic factors together, then correlates this comprehensive data with your flare patterns over time. This approach helps you identify which factors have the greatest impact on your personal uric acid levels, rather than relying on generic food tables that treat everyone the same.

Track Your Personal Response
Everyone responds differently to foods. Urica helps you track how specific foods affect YOUR flare patterns by analyzing purines, fructose, and glycemic load together — not just purines alone.
Frequently Asked Questions
Do foods contain uric acid directly?
Foods do not contain significant amounts of uric acid itself. They contain purines, which are nitrogen-containing compounds found in the DNA and RNA of all living cells. When you digest food, your body breaks down these purines through a series of enzymatic reactions that ultimately produce uric acid as the end product. The enzyme xanthine oxidase catalyzes the final conversion step. So when people refer to uric acid in foods, they are really referring to the purine content that will be converted to uric acid after digestion.
How much uric acid does the body produce from food?
Dietary purines account for approximately one third of total uric acid production. The other two thirds come from your body's own internal cell turnover and purine synthesis. This means that even a perfectly purine-free diet would only eliminate about 33% of uric acid production. In practical terms, strict purine restriction typically lowers serum uric acid by about 1 to 2 mg/dL, which is meaningful but often insufficient on its own for people with significantly elevated levels.
What is a normal uric acid level and how does food affect it?
Normal serum uric acid levels are generally considered to be below 6.8 mg/dL, which is the saturation point where urate crystals can begin to form. For gout patients, rheumatologists often target levels below 6.0 mg/dL. Dietary changes, including reducing high-purine foods and fructose, can typically lower uric acid by 1 to 2 mg/dL. For someone at 8.0 mg/dL, diet alone may bring levels to 6-7 mg/dL, which may or may not be sufficient. This is why medication is often necessary alongside dietary management.
