A. Limiting protein intake is important for individuals with chronic kidney disease to reduce the workload on the kidneys and minimize the accumulation of waste products in the blood. High protein intake can accelerate the progression of kidney damage.
B. Increasing phosphorus intake is not recommended for individuals with chronic kidney disease, as impaired kidney function can lead to elevated phosphorus levels in the blood, which can contribute to complications such as bone disease and cardiovascular issues.
C. Increasing potassium intake is typically not advised for individuals with chronic kidney disease, especially if they have elevated potassium levels (hyperkalemia), as this can further stress the kidneys and increase the risk of cardiac arrhythmias.
D. Limiting calcium intake may be necessary for individuals with certain types of kidney stones, but it is not a general recommendation for all individuals with chronic kidney disease. In fact, calcium is important for bone health, and individuals with chronic kidney disease are at
increased risk of bone mineral disorders.
