In the diet of uremic patients, it is necessary to eat more foods rich in dietary fiber, such as potatoes, groundnuts, pumpkins, etc. Also, because uremic patients are mostly accompanied by edema and hypertension, it is necessary to strictly control salt intake and eat less foods with high salt content, such as pickles, salted fish and salted meat, etc. Uremia is mostly accompanied by oliguria and hyperkalemia, so try to eat less or no food with high potassium ion content, such as popcorn, grapefruit, pomelo, etc., because severe hyperkalemia can easily cause cardiac arrhythmia and even the risk of cardiac arrest. In the diet of uremic patients, try to consume high quality animal protein, such as fish, lean meat, eggs, milk, etc., but the amount should not be too much, and try to eat less vegetable protein, because the amino acids contained in vegetable protein are non-essential amino acids for the human body, and excessive consumption will increase the burden of kidney excretion.
