Is Chocolate Bad for Gout? What It Does to Uric Acid
Dark chocolate, milk chocolate, cocoa powder: their real purine content, why theobromine does not turn into uric acid, and what actually matters with gout.
Is chocolate bad for gout? What it does to uric acid
Short answer: no, chocolate is not a food to fear with gout. Dark chocolate contains about 8 mg of purines per 100 g and milk chocolate about 7 mg: four squares (20 g) provide less than 2 mg, under 0.5% of a 400 mg daily budget. Its weak point is not uric acid but sugar and calories, which matter in the long run.
Gout is caused by excess uric acid, which the body makes when it breaks down purines, compounds found in foods, especially meat, organ meats and seafood. Chocolate often worries people because it contains theobromine, a molecule from the same family as caffeine, with a name that sounds close to "purine". Here is what the evidence actually says.
How many purines are in chocolate?
| Food | Purines (mg/100 g) | Typical serving |
|---|---|---|
| Milk chocolate | about 7 | 20 g (4 squares): about 1.3 mg |
| Dark chocolate with almonds | 6.7 | 20 g: about 1.3 mg |
| Dark chocolate | 8.1 | 20 g: about 1.6 mg |
| Hot chocolate (drink) | 8.1 | one 250 ml mug: about 20 mg |
| Unsweetened cocoa powder | about 71 | one teaspoon (5 g): about 3.5 mg |
| For comparison: cooked chicken breast | 110 to 130 | 150 g: 165 to 195 mg |
| For comparison: canned sardines | 399 | 100 g: 399 mg |
The dark chocolate value comes from the USDA and ODS-NIH Database for the Purine Content of Foods (Release 2, 2025); the others from the Ça Goutte! food database. Cocoa powder is more concentrated, since it is cocoa without the butter or sugar, but you use very little of it.
Theobromine does not turn into uric acid
This is where the confusion comes from. Chocolate contains theobromine, a methylxanthine like the caffeine in coffee. These molecules are structurally close to purines, hence the fear that they raise uric acid. They do not: the body converts them into methyluric acids, compounds that are different from the uric acid that forms gout crystals.
Coffee, whose caffeine belongs to the same family, is even associated with a lower risk of gout in large studies (see our article on coffee and gout). For theobromine, a laboratory study found it slowed the crystallization of uric acid (Grases et al., PLoS One, 2014), but that work was about kidney stones and done in vitro: nothing shows that chocolate protects against gout.
What actually matters: sugar and weight
- Sugar and fructose. Table sugar is half fructose, and fructose raises uric acid. Sugar-sweetened drinks in particular have been linked to a higher risk of gout (Choi and Curhan, BMJ, 2008). A few squares are nothing like a liter of soda, but a whole bar a day or several very sweet hot chocolates can add up.
- Calories. Dark chocolate provides over 500 kcal per 100 g. Excess weight raises uric acid, and losing weight helps lower it (see our article on weight loss and gout).
The best choice is dark chocolate with a high cocoa content (70% or more), which is less sweet, in reasonable amounts: two to four squares a day.
What about during a gout flare?
During a flare, the goal is to limit high-purine foods, alcohol and sugary drinks, and to drink plenty of water. Chocolate fits none of those categories: a square or two changes nothing. Just avoid comforting yourself with a whole bar or very sweet chocolate drinks. For the rest of your diet during a flare, see our guide on what to eat during an acute attack.
During the holidays
At Christmas, chocolate is one of the least risky parts of the meal for purines. The real traps are seafood starters, large servings of meat and alcohol. We go through the whole menu in our article on Christmas dinner with gout.

Frequently Asked Questions
Does chocolate raise uric acid?
Not through purines: dark chocolate contains about 8 mg per 100 g and milk chocolate about 7 mg. Its theobromine is converted into methyluric acids, which are different from uric acid. The sugar it contains can play a role when eaten in large amounts.
Can I eat chocolate during a gout flare?
Yes, in small amounts. A square or two of dark chocolate provides almost no purines. Avoid large amounts and very sweet chocolate drinks, since fructose raises uric acid.
Dark or milk chocolate: which is better for gout?
For purines, the difference is negligible (about 8 versus 7 mg per 100 g). Dark chocolate with a high cocoa content is usually less sweet, which makes it the better choice.
Is cocoa powder high in purines?
It is more concentrated (about 71 mg per 100 g), but a 5 g teaspoon provides only about 3.5 mg of purines.
Does chocolate protect against gout?
There is no evidence that it does. A laboratory study suggests theobromine slows uric acid crystallization in kidney stones, but this has not been shown for gout. This article does not replace medical advice.
