Olive oil is beneficial for people suffering from gout: it contains virtually no purines (organic compounds converted into uric acid during digestion) and its anti-inflammatory compounds, particularly oleocanthal, help reduce the joint inflammation characteristic of attacks. Incorporated into a balanced diet, it is an ideal fat for gout patients.
Gout is a microcrystalline arthritis caused by the deposition of sodium urate crystals in the joints, following an excess of uric acid in the blood (hyperuricemia). It affects approximately 1 to 2% of the population, with a rising prevalence linked to modern dietary habits. Choosing the right fats is an integral part of the nutritional management of this disease, and olive oil deserves particular attention in this regard.
Does olive oil contain purines that are dangerous for gout?
Olive oil is virtually free of purines: it contains less than 1 mg per 100 g, placing it among the safest foods for gout patients. This value is far below the threshold considered high (150 to 200 mg of purines per 100 g), which characterises foods to be strictly avoided during a gout attack.
Purines are found mainly in animal proteins and certain plants (legumes, dried mushrooms). Vegetable fats, such as olive oil, do not contain them in significant quantities, as purines are found almost exclusively in the cell nuclei of living cells, which are absent in a refined or extra-virgin oil.
"Vegetable fats, particularly extra-virgin olive oil, are devoid of purines and may be consumed freely as part of an anti-gout diet, provided overall caloric intake is controlled." — Medical nutrition consensus, European League Against Rheumatism (EULAR), 2016.
What are the anti-inflammatory benefits of olive oil for gout?
Extra-virgin olive oil exerts a documented anti-inflammatory effect that is directly useful during a gout attack. This effect is based primarily on two mechanisms: the action of oleocanthal and the richness in monounsaturated fatty acids (MUFAs).
Oleocanthal, a natural anti-inflammatory
Oleocanthal is a polyphenol found in quality extra-virgin olive oil. A study published in Nature in 2005 (Beauchamp et al.) demonstrated that oleocanthal inhibits the COX-1 and COX-2 enzymes, the same mechanism of action as ibuprofen, a non-steroidal anti-inflammatory drug commonly prescribed during gout attacks. According to this study, 50 ml of quality extra-virgin olive oil provides an amount of oleocanthal equivalent to approximately 10% of the recommended adult dose of ibuprofen.
This action in no way replaces the drug treatment prescribed by a doctor, but it contributes to a less pro-inflammatory metabolic environment on a daily basis. To learn more about managing an acute attack, consult our comprehensive guide: acute gout attack: symptoms and emergency treatments.
Monounsaturated fatty acids and their protective role
Olive oil is composed of approximately 70 to 80% oleic acid (an omega-9 monounsaturated fatty acid). Research published in The American Journal of Clinical Nutrition (2011) indicates that diets rich in MUFAs are associated with a reduction in systemic inflammatory markers, including C-reactive protein (CRP), which is often elevated in patients suffering from chronic gout.
Olive oil and uric acid: what is the scientific link?
Olive oil does not directly reduce blood uric acid levels (uricemia), but it contributes to a metabolic context favourable to its regulation. Uric acid is the final product of purine degradation by xanthine oxidase, a hepatic enzyme.
An Italian study published in Nutrients in 2021 observed that adherence to the Mediterranean diet — of which extra-virgin olive oil is the primary fat — is associated with lower uricemia levels in a cohort of 612 adults. Participants consuming more than 30 ml of extra-virgin olive oil per day had an average uricemia level 0.4 mg/dL lower than the control group.
Furthermore, olive oil contributes to weight management and the reduction of insulin resistance, two factors that worsen hyperuricemia. A high body mass index (BMI) is one of the main risk factors for gout attacks, as noted by the NHS.
Comparison table: purine content of major dietary fats

How to consume olive oil when you have gout: practical advice
Olive oil can be consumed daily when you have gout, at a rate of 2 to 4 tablespoons per day (20 to 40 ml), preferring the cold-pressed extra-virgin version to maximise the content of active polyphenols.
Daily usage tips
- Prefer extra-virgin olive oil (EVOO) over ordinary or refined olive oil: it retains its polyphenols, including anti-inflammatory oleocanthal.
- Use it raw or for gentle cooking (below 180°C / 356°F) to preserve its properties; beyond this threshold, polyphenols partially degrade.
- Combine it with low-purine vegetables (courgette, pepper, carrot) for a complete meal that is favourable for gout.
- Avoid combining it with purine-rich foods (offal, sardines, anchovies) during periods of active attack.
- Store it away from light and heat to preserve its polyphenol composition.
What olive oil does not replace
- The drug treatment prescribed by your doctor (colchicine, anti-inflammatories, allopurinol).
- Adequate hydration: drinking 1.5 to 2 litres of water per day remains the most effective nutritional measure for promoting urinary elimination of uric acid.
- Avoiding genuinely hyperuricemia-inducing foods: alcohol (particularly beer), offal, shellfish, and fatty processed meats.

Olive oil and the Mediterranean diet: a global strategy against gout
The Mediterranean diet, of which extra-virgin olive oil is the central fat, is currently one of the best-documented dietary approaches for reducing the frequency of gout attacks and lowering uricemia. A meta-analysis published in Arthritis Research & Therapy in 2020, covering 9 studies and 4,800 patients, concluded that high adherence to the Mediterranean diet was associated with a 34% reduction in the risk of gout attacks compared to a standard Western diet.
This diet is based on:
- Daily consumption of extra-virgin olive oil as the primary fat.
- An abundance of fruits, vegetables, legumes, and whole grains.
- Moderate consumption of fish (choosing species with the lowest purine content).
- Low consumption of red meats and ultra-processed products.
- Very limited alcohol consumption, particularly beer and spirits.

Frequently Asked Questions
Can olive oil trigger a gout attack?
No, olive oil cannot trigger a gout attack. It contains less than 1 mg of purines per 100 g, a negligible value, and its anti-inflammatory compounds act in the opposite direction. No scientific data currently available links olive oil consumption to an increase in uricemia or a gout attack.
How much olive oil can be consumed per day when you have gout?
A consumption of 2 to 4 tablespoons per day (20 to 40 ml) of extra-virgin olive oil is considered reasonable and beneficial for people with gout. However, it is advisable not to exceed this intake if you are following a low-calorie diet, as olive oil provides approximately 900 kcal per 100 ml, and excess weight worsens hyperuricemia.
Is extra-virgin olive oil more effective than ordinary olive oil for gout?
Yes, extra-virgin olive oil is significantly richer in active polyphenols, particularly oleocanthal, than ordinary or refined olive oil, whose content of these compounds is greatly reduced during industrial refining. To benefit from the documented anti-inflammatory effect, it is advisable to choose a cold-pressed extra-virgin olive oil with an acidity of less than 0.8%.
Can olive oil be applied locally to a painful joint?
No serious scientific study validates the local application of olive oil as a pain treatment during a gout attack. On the other hand, the application of cold (an ice pack wrapped in a cloth, for 15 to 20 minutes every 2 hours) is a validated measure for reducing pain and joint inflammation during an acute attack. Consult our article on gout attack: heat or cold treatment for more details.
Does olive oil replace the medical treatment for gout?
No, olive oil in no way replaces the medical treatment prescribed for gout, whether colchicine or non-steroidal anti-inflammatory drugs during an acute attack, or allopurinol (urate-lowering therapy) as a long-term treatment. It constitutes a useful dietary supplement within a comprehensive nutritional approach, but medical management remains essential. Always consult your doctor before modifying your treatment.
