IgA Nephropathy is a kidney disorder caused by deposits of the protein immunoglobulin A (IgA) inside the glomeruli (filters) within the kidneys. When this happens, the glomeruli cannot filter waste and excess water from the blood, leading to blood and protein in the urine and swelling in the hands and feet. This is a potentially severe condition, and 25% of patients develop end-stage renal disease. Restricting diet may slow the progression of IgA Nephropathy.
Diet are individualized and are often lower, although sometimes higher, in
sodium, potassium, phosphorus, fluid, and protein.
Frequently, you should eat foods that are low in sodium content. A daily
Value percentage of 5% or less is low, and a daily value percentage of 20 or
more is considered high in sodium. To enhance the flavor of food without adding
salt, unsalted herbs and spices, lemon, vinegar can be used. Choose fresh or
frozen foods more often and always check the sodium content of packaged
Limit potassium, phosphorus and fluid intake
Potassium is restricted, so you had better avoid higher potassium foods, such
as milk, yogurt, bananas, beets, peanuts, oranges, potatoes, tomatoes, avocados,
prunes, figs, dates, raisins, nectarines, apricots, melons and pears.
Some patients are instructed to reduce phosphorus levels. Foods higher in
phosphorus include whole grains, dairy, legumes, shellfish, bran, chocolate,
soft drinks and beer.
You also need to consume less amount of fluid during a meal, use smaller cups
for beverages, and snack on ice cubes other than drinking waster.
Restrict the intake of protein
Protein can help maintain the muscle mass and support a healthy immune
system. However, with kidney impairment, you need to limit the intake, because
the kidneys are responsible for filtering the wastes of protein metabolism from
the blood. Therefore, you are suggested to avoid eating too much milk, cheese,
yogurt, fish, meat or eggs.
