The goal of diet treatment
One thing you should know is that diet just help you prevent or relieve some symptoms of kidney disease. It cannot be taken as a treatment. In Stage 4 Chronic Kidney Failure, the kidney function is severely decreased, leaving many wastes and toxins building up in the body and lead to uremia with symptoms like nausea, vomiting, loss of appetite, abnormal taste, bad breath, nerve and sleep problems, difficulty concentrating and fatigue. Fluid retention due to a decrease in urine output may also occur.
Stage 4 Kidney Failure patients are suggested to take 0.6-0.8 grams per kg of body weight, since the glomerular filtration rate has decreased to less than 30ml/min, or approximately 29% percent remaining kidney function. Half of the protein should come from high-quality sources that provide all the essential amino acids, such as egg white, milk, seafood, lead meat, soy).
Phosphorous and potassium
These two minerals are essential but cannot be taken too much in Stage 4 Chronic Kidney Failure patients, or many other complications will occur. In general, your diet may include a phosphorous restriction of 800-1,000 mg daily, and a potassium restriction of 2,000 to 3,000 mg a day.
High phosphorous foods you should limit: Cheese, ice cream, nuts and seeds, chocolate, etc.
High potassium foods not recommended: Banana, dried fruit, avocado, potatoes, tomatoes, citrus fruits, pumpkin.
Most kidney diet start with a goal of 1,500 to 2,000 mg per day. The sodium recommendation for Stage 4 CKD is 1,000-4,000 mg/day based on fluid balance, blood pressure and other disease.
If you have swelling, you should also limit your fluid intake. The right amount depends on your body weight and urine output. Consult your nephrologist or dietitian for suggestions. Or you can ask our doctors online directly.
