Serving Portions to Consider for Diet for CKD Patients

A kidney patient’s meal program demands certain specific factors like the type of foods to eat and the serving portions. It is established that in a diet for CKD patients, serving portions play a vital role. This is to ascertain that a person with a kidney disease gets the needed nutrients that are required for his body and making sure that these minerals do not go beyond the recommended dosage. For this, it is understood that every kidney patient should learn the essential serving portions that are included in a kidney diet.


Protein in Diet for Renal Patients

Protein is considered as an essential mineral in our bodies. Some of the functions that it plays in our system include that of healing wounds as well as muscle and tissue repair. Protein can be found in foods such as beef, lamb, chicken, fish and eggs. Generally, protein is needed in our bodies but for a CKD patient, this rule does not necessarily apply. Depending on your kidneys’ status, your protein intake also varies. There are those kidney patients that need more protein consumption and those that are recommended with a little portion serving only.  In most instances, a suggested protein size in kidney diet is that of a palm size.

Sodium in kidney disease and Diet

Apart from protein, another mineral that should be considered in a kidney diet is sodium. Excess sodium consumption can lead to various problems such as high blood pressure and the puffiness or swelling of feet and ankles. For this, sodium intake should be watched which means limitation of not using more than a pinch of salt in cooking. Another helpful ways to avoid salt consumption include:

  • Avoid foods with high sodium content
  • Ham, bacon, sausages, corned beef, smoked fish
  • Salted chips and salted nuts
  • Instant noodles and soups, Salty crackers
  • Salty sauces and dips
  • Most take-out foods
  • Refrain from using salt to food in the table
  • Opt for canned and packet foods that only contains 450mg or less sodium per 100g

More helpful suggestions:

  • Prefer the use of iodized salt
  • Not all salt substitutes are not suitable in place of salt in all instances
  • Use other spices for sodium flavoring such as garlic, onion, fresh herbs, peppers and other spices.
  • To retain vegetables flavor, steam them.

As to Fruits and Vegetables

As for potassium in fruits and vegetables, aim for 5 serves of fruit and vegetables/ day.

That is, 2 serves of fruit & 3 serve of vegetables in a day or the other way around. To get most of your vegetables and to reduce its potassium content, cut, boil and drain your vegetables.

For carbohydrates, keep the serving portion to a ‘fist’ size/ day

Another thing to be taken into account when it comes to Diet for CKD patients is phosphate.

It is vital to bear in mind that the consumption of these food choices is subject to the doctor’s recommendations. Depending on your lab results and tests and your kidneys’ state, the intake of these foods may also vary to different kidney patients.
