A reasonable diet is very important for the recovery of kidney disease patients. What to eat? How much is appropriate? This cannot be explained in a sentence or two. It is necessary to formulate a plan for each individual based on the type of disease and the severity of the condition.
Can kidney disease patients eat salt and alkali? How much? Salt is sodium chloride, alkali is sodium carbonate, and baking soda is sodium bicarbonate. Consuming too much sodium-containing salt and alkali can easily lead to water retention in the body, inducing edema. Therefore, patients with renal edema should control their intake of salt and alkali and can follow a low-salt diet. A low-salt diet is defined as consuming 2-3 grams of salt per person per day. A salt-free diet is not scientific, as long-term adherence can lead to symptoms such as fatigue and dizziness.
How much water should kidney disease patients drink? The normal urine output for a person is generally 1-2 kilograms per day. Patients with acute nephritis, the oliguric phase of acute renal failure, and patients with nephrotic syndrome or chronic renal failure with oliguria and edema need to control their water intake. Because water that is consumed cannot be excreted, it is retained in the body, worsening edema and also easily aggravating hypertension. At this time, the water intake should be the previous day's urine output plus 500 milliliters. As urine output increases, water intake can be relaxed, while patients with normal urine output have no restriction on water intake.
Can kidney disease patients eat fish, shrimp, eggs, and meat? Many kidney disease patients believe they cannot eat fish and shrimp. In fact, these foods are high-quality protein. With the exception of individuals with allergic diseases such as allergic purpura or purpuric nephritis, where it is suspected to be related to foreign protein allergy, or those with a history of fish and shrimp allergies who should eat them with caution, there is generally no need to avoid them. Fish, shrimp, eggs, and meat are rich in animal protein, which is the main structural material for human cells and tissues and is very important for the body. However, after consuming protein-containing foods, they are broken down by the liver and excreted by the kidneys. Therefore, when kidney function declines, protein intake should be appropriately reduced. The principle should be to meet the body's metabolic and nutritional needs without increasing the burden on the kidneys.
