High uric acid: which foods to avoid?

What is uric acid and why can it become problematic?

First of all, what is it? To start, uric acid is naturally found in the blood. It is a by-product that results from the breakdown of purines during digestion.

We will discuss uric acid when it is in excess; because it can lead to serious health issues, such as gout or joint inflammation.

Foods to limit in case of uric acid

1. Offal

In cases of hyperuricemia (uric acid levels in the blood higher than 80 mg/L), certain foods high in purines should be avoided. Offal, such as liver, kidneys, sweetbreads, or cheeks, are among the most discouraged.

2. Processed meats

Processed meats, along with all animal protein sources, should also be banned. These products contain not only purines but also saturated fats, which reduce the body's ability to eliminate uric acid.

3. Fatty fish

To reduce uric acid levels, eliminated by the intestines and kidneys before being excreted in urine, it is advisable to limit the consumption of seafood and fatty fish such as anchovies, herring, and salmon.

4. Asparagus

Certain vegetables, like asparagus, should also be consumed in moderation. Cauliflower, spinach, and mushrooms are not recommended either.

5. Chocolate

Although dark chocolate has many benefits (brain stimulation, mood improvement), it generates uric acid during its metabolism. People suffering from hyperuricemia should therefore avoid it.

6. Lentils

Lentils, as well as other legumes like chickpeas, red beans, white beans, green peas, and fava beans, are also high in purines and should be consumed with caution.

7. Dried fruits

Dried figs, as well as dates, apricots, and prunes, while beneficial for health, should be consumed in moderation due to their high purine content.

8. Beer

Beer is a drink to avoid in case of hyperuricemia, as it contains purines that can raise uric acid levels in the blood. Additionally, alcohol slows down the elimination of uric acid by the kidneys, worsening the situation.

9. Sugary drinks

Sugary drinks, such as sodas and sweet fruit juices, contain fructose, a sugar that can increase uric acid production. Reducing their consumption helps prevent complications related to excess uric acid.

10. White bread and refined products

Simple carbohydrates found in products made from refined white flour, such as white bread, pasta, and cakes, can contribute to increased uric acid levels by indirectly raising blood sugar levels.

11. Wine and spirits

In addition to beer, other alcoholic beverages like wine and spirits can also increase uric acid levels, as alcohol interferes with the elimination of this compound by the kidneys.

12. Red meats and poultry

Finally, aside from offal and processed meats, it is advisable to limit the consumption of red meats (beef, lamb) and certain poultry, as they are also high in purines.

In summary

To prevent and manage hyperuricemia, it is crucial to monitor one’s diet by limiting foods high in purines, such as certain offal, meats, fatty fish, legumes, and refined products. Reducing alcohol, sugary drinks, and chocolate consumption can also help maintain a healthy uric acid level, thus preventing serious conditions like gout. Adopting a balanced and varied diet remains key to controlling these levels and preserving health.
