You can prevent or delay health problems from chronic kidney disease (CKD) by eating the right foods and avoiding foods high in phosphorus, potassium, and sodium. Eating too much protein can also burden the kidneys and speed the progression of CKD. Protein foods like meat and dairy products break down into nitrogen and creatinine, waste products that healthy kidneys remove from the blood. But diseased kidneys can’t stop waste products from building up in the blood and causing health problems.
With reduced kidney function, you may need to start paying attention to the protein, phosphorus, sodium, and potassium content of the foods you eat. Learning about your food will help you understand what changes you need to make.
