Amount and type of proteins recommended for advanced kidney disease
PROTEINS FOR CHRONIC RENAL INSUFFICIENCY
Control of proteins in chronic renal failure
One of the most important changes in the diet for kidney disease is that people suffering from it should decrease practically all rations of protein. That is, eat less meat, fish, eggs, legumes and dairy.
In addition to protein control, other sources of phosphorus (not just proteins), such as carbonate beberages and other phosphate additives, should be avoided. The goal is to decrease metabolic acidosis and slow kidney damage.
If there is no potassium restriction (specifically prescribed by your doctor), a diet rich in vegetables and legumes is recommended.
The following section specifies what amounts and types of protein-rich foods are adequate, and which ones should not be consumed.
How much protein should be consumed?
The recommended protein intake ranges from 0.6 to 0.8 g of protein per kg of body weight per day (g protein / kg / day). Following the previous case, in a man weighing 87 kg, the dietary pattern will be between 52 and up to a maximum of 70 g of protein per day.
Therefore, the percentage of daily energy from proteins will be close to 10%, instead of the 15% that is recommended in a standard diet. The oil intake should be slightly increased to compensate.
Protein-rich food rations
Below, there is a table with the protein rations and the appropriate protein rich foods. Each diet should be adjusted according to the characteristics of the person and the stage of his illness (consult with the practitioner).
Can you take a vegetarian diet if there is chronic kidney failure?
A vegetarian diet is beneficial for patients with kidney failure. In fact, the National Kidney Foundation recommends a vegetarian diet, or mostly vegetarian, for patients with kidney disease. The main advantages of this type of diet are: decrease of cardiovascular risk, decrease of proteinuria, and decrease of kidney damage.
Foods rich in plant proteins are also very rich in potassium. You should decrease your intake if you must carry a diet low in potassium. However, there is no reason to restrict vegetable consumption if the nephrologist does not indicate potassium control.
Example of protein intake in a kidney patient
The following is an example of a healthy diet for kidney failure, with the calculation of daily protein that is performed:
DIET ANNOTATIONS EXAMPLE:
* = Vegetable foods (fruits, vegetables) should always be pre-soaked: peel, chop and soak at least 12 hours to remove the potassium they contain
- Do not use herbs directly because they contain a lot of potassium, you can scent the oil with macerations (herbal oil)
- Do not use salt or baking soda in cooking (such as it is generally adviced when cooking legumes)
Dairy in kidney disease
Dairy products are nutritious foods that can be consumed, but are not highly recommended because of their phosphorus and protein content. Therefore, it must be taken into account that its consumption should be moderate, respecting the rations mentioned.
How is a certain food considered to be adequate or unsuitable for CRI?
Some readers may wonder why some foods from the above list are appropriate, and why others are not. This section solves this doubt.
Proteins are essential nutrients and vitally important to the body, which you have to ingest through food. However, not all protein-rich foods are just as suitable for kidney disease.
In chronic renal failure, it is desired that protein foods carry the least possible renal load during their metabolism. For that, in the past, its purine or urate content was taken into account. Currently, the criterion to follow is the so-called phosphate / protein ratio of food.
The phosphate / protein ratio of food is a dietary criterion supported by scientific evidence and recommended in the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) guidelines for good dietary phosphorus control.
Relationship between proteins and phosphorus
Phosphorus is a mineral found primarily as part of proteins. It is important to control phosphorus because its excess produces hyperphosphatemia (abnormally high levels of phosphate in the blood), which, in turn, causes calcification of the arteries and increases the cardiovascular risk of the person with CRF.

Doubts about chronic kidney disease
How much fluid can the person with CRF drink? How should potassium be removed? What foods have more potassium?...
Botanical online has developed this detailed guide which explains in detail all the information related to feeding in the chronic renal patient, in order to resolve doubts and facilitate access to a proper diet.
It is recommended that you consult with your doctor any dietary changes that will be made:
