Eat Healthily
If you want to slow kidney disease progression, you also need to eat healthily. That means staying away from foods that are too high in salt content. Your diet should ideally contain no more than 2,300 milligrams of sodium each day. It also means eating food that contains an adequate amount of protein and is heart-healthy, such as fruits, veggies, and lean meats. There are also certain things that need to be restricted in the late stages of the disease, such as phosphorus and potassium. Phosphorus can be found in dark-colored sodas.
