 Foods to avoid in case of excess uric acid (hyperuricemia)

Excess uric acid in the blood, or hyperuricemia, is caused by eating too much of certain foods high in purine. It can cause gout attacks, a special form of arthritis that mostly affects men between the ages of 30 and 60. Update on foods to avoid and good dietary rules to follow to avoid it.

Purines are nitrogenous molecules found in living organisms. They play an important role in certain reactions of the body. For example, they provide essential elements to DNA.

What is uric acid?

Uric acid is produced by the breakdown of purines naturally present in foods of plant and animal origin by the body. It is normally eliminated through the intestine and kidneys and expelled through the urine. Normal values   of uric acid are between 40 to 60 mg / L (or 240 to 360 mol / L) for men, between 30 to 50 mg / L (or 180 to 300 mol / L) for women and between 25 to 40 mg / L (or 150 to 240 mol / L) for the child. 

But, in case of a too high level of uric acid in the body, either one makes too much of it or one does not eliminate it enough.

To reduce the level of uric acid in the blood, Anne Guillot, a dietician nutritionist reviews some dietary rules and foods to avoid or consume in moderation.

Foods rich in purines to avoid

Here are the main foods to avoid excess uric acid:

• red meat ;

• offal;

• deli ;

• dried (or smoked) meat or fish;

• Cubic broths (330 mg of purines for 10 grams *, ie the equivalent of a portion of offal);

• Strong alcohols;

• Beer (even without alcohol: brewer's yeast provides 300 mg of a purine for 10 grams *);

• Sodas and fruit juices are high in fructose.

But beware, some pieces of white meat can also have a high level of purines.

“Offal and red meat are particularly to be avoided, but in reality, you have to take into account the piece of meat to establish its richness in purine. For example, pork tenderloin will show 146.2 mg of uric acid per 100 grams while the shoulder will only contain 81.4 "explains Anne Guillot, dietitian nutritionist ( /).

Seafood should also be watched, in particular seafood and small oily fish, such as canned mackerel and sardines.

Depending on the food, we have chosen measures close to the dosages used in everyday life (10 grams for bouillon cube or spirulina, 100 grams for a portion of meat).

Promote its elimination

To reduce the level of uric acid, it is also possible to play on the elimination of purines. For that, no secret, it is, therefore, necessary to drink abundantly, 2 liters of water per day.

Finally, even if it is adorned with multiple virtues, spirulina is also to be left in the closet. This seaweed contains 107 mg of purine per 10 grams.

"According to a study published in 2012, plants do not pose a problem, because plant" purines "do not turn into uric acid", explains Anne Guillot.

To know all the concentrations of uric acid in food. If this site is intended for the feeding of domestic animals, the purine values are also valid for human beings.

Foods to watch out for

"Certain foods can promote the onset of a gout attack, even though they do not contain uric acid, and this by complicated biological mechanisms", explains Anne Guillot. Among them, we identified chocolate, mushrooms, cabbage, asparagus, sorrel, spinach, rhubarb, dried figs, etc.).

If dairy products low in fat (fresh cheese, less than 20%, yogurt, semi-skimmed milk) promote the elimination of uric acid, it is recommended to limit its daily intake of fat and sugars to avoid an increase in insulin which will inhibit the elimination of uric acid.

If in doubt, do not hesitate to consult a nutritionist and/or a dietitian who will help you regulate your consumption of purines.
