Stage 3 Chronic Kidney Disease(CKD) Diet

In Stage 3 CKD,GFR is approximately 30-60%: GFR 45-59 (3A) or 30-44 (3B). Rememember that GFR is an estimate and may require a correction for (black) race.Developing a healthy lifestyle may be able to help prevent some long-term complications of kidney disease like bone disease or heart problems and maintain the kidney function for as long as possible.

Stage 3 chronic kidney disease is defined as having moderate kidney damage that limits some of the filtering ability of the kidneys, but doesn't necessitate dialysis. Decreasing the level of waste by making diet modifications preserves the remaining function and staves off further damage.

Protein Restrictions

Protein serves to maintain muscle mass and support your immune system. Urea is a by-product of protein breakdown by the liver. Your kidneys take the urea and produce urine for excretion of waste products. Reducing your protein intake reduces the amount of urea produced and, thus, the workload of the kidneys. However, according to DaVita, a dialysis facility for kidney failure, for stage 3, a dietitian will usually recommend eating a healthy diet with protein at the level of 0.8 grams of protein per kilogram of body weight, the same level recommended for all healthy people. One kilogram of body weight is equivalent to 2.2 lb.

Phosphorus and Calcium

Phosphorus is a mineral that works with calcium to support bone health. As your kidney function worsens, phosphorus can build up in the blood causing itchy skin and your bones to lose calcium. This stage of the diet restricts the amount of phosphorus in your diet by limiting beans, legumes, beer and dark colored carbonated beverages. Phosphorus binders can be used to remove excess phosphorus from your ingested food. These binders are usually concentrated calcium supplements because phosphorus and calcium compete for absorption in your intestines. Providing high amounts of calcium with your meals decreases the amount of phosphorus your body absorbs, thereby preventing kidney associated bone disease.

Fat-Soluble Vitamins

Fat-soluble vitamins A, D, E and K may have to be taken in water-soluble form, according to DaVita. Switching to water-soluble forms prevents buildup of these fat-soluble vitamins. Increasing the availability of vitamin D in water-soluble form is helpful as your kidneys may not be able to convert UV light into the active form of vitamin D.

Fluid Restrictions

Fluid isn't restricted on the stage 3 diet for chronic kidney disease. Your kidneys are still filtering your blood with some limitations. Stage 3 chronic kidney disease doesn't warrant a change in how much fluid and water you drink per day. If the filtration rate of your kidneys decreases, your physician may restrict how much fluid you can have per day to delay dialysis.
