CKD is a progressive disease, causing permanent damage to the kidneys.

It advances through 5 stages. Treatment and advice will vary depending on the stage of the kidney disease.

Your kidneys filter waste from your blood. When the kidneys become diseased, their function decreases, and waste products can end up in the blood.

The Key Nutrients to Keep in Mind:

A healthy, balanced diet is important in managing CKD.

Protein

Fluid

Sodium

Phosphate

A healthy, balanced diet is important in managing CKD.

Protein

Protein is important for building muscles and repairing tissues. Consuming too much, however, can lead to build up of urea (a waste product from protein) in your blood, while consuming too little can cause muscle loss.

Aim for a moderate intake of protein each day from a variety of foods including meat, fish, chicken, eggs, nuts, and lentils.

Fluid

Your healthcare professional may recommend you limit your fluid intake. If so, remember foods that are liquid at room temperature, like jelly and ice cream, contribute to your fluid allowance.

Water, jelly, gravy, softdrinks, and custard also contribute fluid.

Sodium

Excess sodium (or salt) causes the body to hold onto extra fluid, contributing to high blood pressure, fluid retention, and shortness of breath. Avoid adding salt in cooking and minimise high sodium foods including processed meats, sauces, snack foods, stocks, and takeaways.

Use herbs, spices, and condiments to add flavour – your taste buds will slowly forget the salt.

Phosphate

Phosphate or phosphorus is a mineral stored in bones that helps to keep them strong. The kidneys filter the blood to help remove excess phosphate. With CKD, however, this doesn’t happen as effectively, so phosphate can build up in the blood.

You may need to reduce your intake of phosphate-containing foods or take a phosphate-binding medication with your meals and snacks.
