Why is a protein restricted diet important in predialysis?
Wastes derived from catabolising protein have to be excreted via your kidneys. In chronic kidney disease patients, when the kidney function is impaired, the waste products cannot be eliminated properly. As the waste products are poison for the body, patients who have not received dialysis yet, are advised to restrict their protein intake. Therefore, fewer wastes will be generated while consuming a protein-restricted diet, and the kidneys are disburdened.
Suffering from CKD, what is a patient supposed/allowed to eat?
In general, it is recommended to eat low amounts of sodium (especially table salt), low amounts of phosphate (e.g. seafood, cereals, chocolate, bean products etc.) and sufficient calories. Furthermore, patients in the predialysis stage should eat low amounts of protein.
Which foods should I avoid during my protein restricted diet in predialysis?
Since a protein-restricted diet is mainly a vegetarian diet, meat, fish, eggs, cheese, milk/milk products are only allowed in very limited amounts. Please talk to your doctor or dietitian to find out about your daily protein intake.
How do I know which treatment options fit me best?
As this has to be decided upon your disease history and individual situation, please ask your doctor or dietitian.
