Special diets for the treatment of kidney disease have been available for many years.
Before dialysis and modern medications were available, the only available treatment for kidney disease was a special diet.
People with kidney disease were placed on low-protein diets in the hope that the progression of kidney disease would be slowed.In addition, intake of salt, potassium, phosphorus, and fluid was restricted.
People on these diets could live longer, but the quality of their life was poor.
They often became malnourished.
