What is diet therapy for chronic renal failure??

Chronic renal failure patients with blood retention of nitrogen. In the conservative treatment must be accompanied by diet therapy to limit the amount of protein to reduce the retention of nitrogen; reduce the body's protein decomposition, to correct the body of amino acid metabolism abnormalities, to maintain the total balance of nitrogen; to ensure nutrition, enhance resistance, slow the disease development, relieve complications.

What is diet therapy for chronic renal failure??Eat low protein, high nutritional value protein: that is, low amount and high quality. The progression of chronic renal failure can be blocked or delayed by limiting the amount of protein. High nutritional proteins are called high quality proteins, which contain high levels of essential amino acids, and are less nitrogen producing substances after decomposition in vivo. Should choose animal protein, such as eggs, milk, lean meat and so on. Vegetable proteins generally contain non essential amino acids, and have low biological potency, so they should be restricted. Especially the staple foods containing higher protein in plants, such as corn, flour, etc, which can cause further deterioration of renal function should be limited strictly.

Calorie intake should be sufficient: changes in food fat can affect the progress of different types of kidney disease, including unsaturated fatty acids, such as linoleic acid, etc, confirmed by experiment, can prevent deterioration of renal function. Because linoleic acid is a precursor of synthetic prostaglandins, by affecting the level of prostaglandins and renal function play a protective role. Therefore, in order to ensure the supply of unsaturated fatty acids in food, vegetable oil should be replaced with animal fat.

Should pay attention to maintain the normal level of various vitamins: patients with chronic renal failure have too little vitamin intake because of poor appetite; in addition, uremia itself can lead to changes in water-soluble vitamin metabolism, so patients with chronic renal failure should pay attention to supplement of vitamin B family, Vitamin C and so on. And should not supply vitamin A, because vitamin A of body increased, it can stimulate the secretion of thyroid hormones lead to renal bone malnutrition, which can also cause fat metabolism disorders, resulting in increased levels of cholesterol, triglycerides. Moreover, chronic renal failure, 1,25 dihydroxyalcitrification alcohol production is insufficient, resulting in calcium and phosphorus and bone metabolic disorders, renal bone disease, and therefore should also pay attention to vitamin D supplement.
