Oxalate Kidney Diet

General rules

In the structure of deferred calculi in the ICD oxalates (salt calcium oxalate) occupy a leading place.

The main predisposing factor for the formation of calcium-oxalate stones is hyperoxaluria, which refers to high urinary excretion (more than 40 mg per day) oxalic acid. An oxalic acid anion combines with a calcium cation to form a soluble salt calcium oxalatemost often in the form of a monohydrate - wavellite (calcium oxalate monohydrate) and dihydrate - Weddel (calcium oxalate dihydrate).

One of the reasons for the formation of oxalate calculi in the kidneys is an excessive intake of oxalates from food or an increase in intestinal permeability, which contributes to increased penetration oxalic acid through the intestinal mucosa and its entry through the kidneys into the urine.

This is due to a deficiency of calcium that binds oxalates in the intestines. High absorption of oxalates in the intestine is mainly associated with a violation of the digestion of fats. Increased oxalate formation may also be due to excessive consumption. ascorbic acid, including synthetic, which is metabolized in the body to oxalic acidinsufficient dietary magnesium and vitamin b6. In this regard, in complex treatment oxalate urolithiasis diet therapy prevails.

Hypooxalate diet is aimed at:

  • exclusion / limitation of foods high in oxalic acid from the diet;
  • normalization of the exchange of oxalates;
  • decreased synthesis of oxalates in the body;
  • decreased absorption of oxalates in the intestine;
  • active excretion of oxalates in the urine;
  • deficit elimination vitamin b6 and magnesium.

The diet for oxalate kidney stones provides for the complete exclusion from the diet of foods containing large amounts of oxalic acid - offal (kidneys, tongue, brain, liver), meat and fish broth, salted fish, spicy salt cheese, jellied meat, spinach, sorrel, chocolate , gelatin, rhubarb, tomatoes, celery.

For quantity reference oxalic acid 4 product groups can be distinguished:

  • a large amount (> 1 g / kg) - in spinach, parsley, cocoa beans, rhubarb, chocolate, sorrel, celery;
  • moderate amount (0.3-1.0 g / kg) - in chicory, tea, carrots, green beans, beets, onions, tomatoes;
  • a small amount (0.05-0.3 g / kg) - in apricots, fresh cabbage, Brussels sprouts, bananas, currants, potatoes.

Baked Cauliflower

Minimal amount oxalic acid have cucumbers, eggplant, pumpkin, lettuce, mushrooms, cauliflower, peas. However, the content of oxalic acid in products is largely determined by the type of soil and the technology of their cultivation.

If a stone is found in the kidneys and an inflammatory process develops in the kidneys or urinary tract, the following is prohibited: spicy foods, seasonings, pickles, smoked meats, marinades, horseradish, mustard, vinegar, fish caviar, onions, garlic, eggs (1 egg per day), alcoholic beverages .

With oxalates in the kidneys, to reduce absorption in intestinal pathology, you should limit the intake of fats to 60 g in the diet and include foods with a sufficient calcium content in it. It is also recommended to reduce the amount of carbohydrates in the daily diet to 300 g, since it is possible to synthesize oxalic acid in the intestines from carbohydrates under the influence of intestinal bacteria.

The amount of protein is at the level of 100 g. At the same time, meat, poultry, cooked sausages are consumed only in moderate amounts (up to 150 g / day), it is better in boiled form. It is also necessary to limit the consumption of milk, cottage cheese and cheese, but you do not need to completely abandon them. Preference is given to sour-milk and non-fat dairy products and to use them is recommended in the morning.

Since oxalates in MKD are often formed with a lack of magnesium and vitamin b6 the diet should include foods rich in magnesium: wheat bran, oatmeal, buckwheat, pearl barley, wholemeal bread, dried apricots, oatmeal, peas, soybeans, seaweed, beans, radish. In this case, magnesium oxalateswhich compared to calcium oxalates well soluble in water.

Limit high-content foods Vitamin C - gooseberries, currants, rose hips, cranberries, oranges, tangerines, mountain ash, wild strawberries, grapefruit, strawberries, lemon, wild leek, sweet red pepper, dill, horseradish.

To prevent the precipitation of calcium oxalates in the form of sediment and reduce the concentration of oxalic acid in the urine, it is necessary to ensure high diuresis (in the absence of contraindications) by increasing the intake of free fluid - up to 3.0 liters per day and limiting the intake of sodium chloride, which retains fluid in the body. At the same time, it is necessary to use the liquid not just in the form of water, but alternating with juices, fruit teas, compotes, decoctions (vegetable and fruit), since weak organic acids (malic, citric, lactic, benzoic, formic, fumaric) contained in these drinks dissolves oxalate stones.

Essentuki healing mineral water №4

Diet for oxalates in the urine involves drinking beverages and foods that contribute to change pH urine. To alkalize urine, it is recommended to include mineral water in the free fluid volume Naftusya, Truskavetskaya, Berezovskaya, Essentuki №4 and №20, Luzhansk, Morshinskayaas well as cucumber and other vegetable juices.

The presence of oxalate salt in urine is also found in children of different ages. At the same time, the appearance in the urine of a child of oxalates may also be a sign of the presence of another pathology, which will be discussed in the appropriate section below.

A few words about oxalaturia. Oxalaturia (oxalate diathesis), is, in fact, a harbinger urolithiasis. Against this background, the threat of the formation of "sand" or stones in the kidneys sharply increases. However, with oxalaturia, there is no urgent need to observe a very strict milk-vegetable ("alkaline") diet. It is enough to exclude foods rich in oxalic acid from the diet, as well as limit foods containing carbohydrates, salt, strong broths, fried meat and fish. It is important to control indicators pH urine given that pH in the range of 5.5-6.5 is optimal for the precipitation of oxalic acid salts.

There are no special requirements for the culinary processing of products, but at the same time it is preferable to boil or stew the products.


  • Oxalaturia in adults and children.
  • Urolithiasis disease in the presence of stones of oxalate etiology.

For children

Since the urinary system of children is physiologically immature, the kidneys, in some cases, are not yet able to fully support the dissolved salts. First of all, non-episodic increased content oxalates in the urine of a child should be a serious reason for his in-depth examination and the exclusion of pathologies of the development of the urinary system and diseases (intestinal infections, kidney diseases, endocrine diseases). However, most often, the presence of oxalates in the urine of a child is caused by an unbalanced diet with the consumption of foods rich in oxalic acid, insufficient fluid intake or intense sweating (with increased physical exertion, hot weather). The acceptable norm is the episodic presence of calcium salts of oxalate in the urine in a concentration of "++".

The diet for oxaluria (a diet for children) has some features that determine the nature of the diet and drinking regimen. Despite the general approaches to allowed and forbidden foods, a hypooxalate diet should not just copy the diet of adult nutrition, but also take into account that the growing body of a child needs sufficient intake of proteins, fats, carbohydrates, minerals and vitamins. Therefore, only products with an oxalic acid content of more than 50 mg / 100 g should be excluded from the diet and foods with its content from 5 to 50 mg / 100 g should be limited.

It is also unacceptable to deprive a child of dairy products - at this age, the skeleton is actively formed and insufficient calcium in the diet can lead to negative consequences. It is important to monitor the amount of daily intake in the body vitaminsas with products - blackcurrant, rosehip, Antonovka, radish and others, and with drugs, since the formation of oxalic acid in the body increases with its consumption of more than 150-200 m / day.

The drinking regimen of the child requires special attention. The daily volume is recommended to be increased by 50% of the required age volume. At the same time, it is especially important not to limit the intake of fluid at bedtime, but rather, in the evening, the amount of fluid consumed should be increased. It is recommended to use slightly alkaline mineral waters, fruit drinks from cranberries or cranberries, tea from cherry and pear leaves, and a decoction of flax seed before meals.

Advantages and disadvantages

  • Available on a set of products and not expensive.
  • Normalizes the content of oxalic acid in the body, with oxaluria reduces the risk of formation of conglomerates of oxalate etiology.
  • Long period of being on a diet.
  • Effective mainly with oxaluria and the initial stages of the formation of oxalate stones.


  • To increase the effectiveness of dietary nutrition, it is recommended to lead an active lifestyle (high physical activity - playing sports, fitness).
  • Avoid emotional stress.
  • Do not abuse alcohol.
  • Control your weight as urolithiasis more common in obese patients.

Feedback and Results

Reviews about diet with urolithic urolithiasis vary significantly. Obviously, this should be so, since dietary nutrition in the presence of already large formed conglomerates of oxalate etiology is weakly effective. Conversely, with oxaluria, the appointment of a diet can prevent the process of stone formation.

  • "... Urolithiasis for 5 years. Periodically dieted, but the stones did not decrease in size. And after the frequent appearance of colic went to surgery";
  • "... When analyzing urine for an infectious disease, a high content of oxalic acid was found. Assigned a diet. I ate with restrictions for almost 6 months. I gave urine again for analysis - everything returned to normal".

Diet price

Therapeutic nutrition for oxalate stones in the kidneys is not too expensive, because the menu includes affordable products and offers a wide selection of them, which allows you to vary them and adjust the cost of food according to your financial capabilities. The diet is dominated by cereals, fruits, vegetables, and protein foods make up a smaller share in the diet.

Costs per week approximately vary between 1800 - 2000 rubles.
