Nutrients to limit
When suffering from kidney failure, it is advisable to limit intake of sodium, protein, potassium and phosphorous. Excessive intake of these nutrients may in fact overwork the kidneys, as they function in a limited way due to the insufficiency.

Foods to limit
The best way to obtain correct information on the diet to follow in the case of kidney failure is to consult a doctor. In general, it is believed that protein-rich foods (meat, fish, eggs, dairy products), potassium-rich foods (bananas, sweet potatoes, spinach, etc.) and phosphorus-rich foods (fish, canned foods, etc.) should be restricted.
