Good proteins
Under the premise of meeting patients’ need for proteins, limit daily protein intake to relieve burdens and strains to the kidneys especially if their blood urea nitrogen is still high. Animal protein is preferred than vegetable protein because they produce less nitrogen-related wastes and toxins after metabolism. Good proteins include lean meat, fish, chicken, shrimps, etc.
Low-salt diets
Renal failure patients often have high blood pressure which can be well controlled and prevented with low-salt diets. Limiting salt intake is especially important in case of swelling.
Low-potassium
Renal failure often suffer from high blood potassium which can affect their heart function and in serious conditions can even cause sudden cardiac arrest. Therefore if patients already have hyperkalaemia, it is very important to limit high-potassium foods. Potassium content can be lowered after being frozen or boiled in water.
Limit the sugar intake
For this patient, because of his diabetes, he need to limit his daily sugar intake in order to control his high blood sugar. Because the high blood sugar will increase the progression of kidney failure.
Renal failure patients should try to avoid hot pepper, chili, curry, fennel, chocolate, melon seed and peanuts as well as sea products, alcohol and tobacco, etc.
