An important feature of patients with renal impairment test a large number of proteins in the urine, and renal function is to reabsorb the protein, but now there is protein in the urine, indicating that the kidneys can not assume this responsibility, what has been renal failure. That being the case, it is necessary to supplement the protein through the diet. From here we see an important role in the diet of kidney failure.
(1) Vitamin Supplements: when chronic renal failure, should supplement vitamin preparations, because patients with more complicated with poor digestion and absorption chronic renal insufficiency, vitamin supplements with food can not meet the needs of body metabolism .
(2) Maintain the water balance: Patients with chronic renal failure is very important in the water balance. Fluid intake is determined according to the discharge amount. Should be under the supervision of a physician, liquid supplement to prevent more water intake, discharge disorder, edema worsened.
(3) Provide dietary calcium phosphorus: Partly patients with chronic renal failure, may have the phenomenon of elevated serum phosphorus and calcium decreases, therefore, induced osteoporosis. Ideal diet should increase calcium content lower phosphorus content. Foods rich in calcium are milk, green leafy vegetables, sesame etc. When cooking fish and lean meat, Boiled then remove and then fried, can reduce the phosphorus content of fish and meat.
(4) When chronic renal failure is high blood potassium, should be limited to potassium foods, avoid eating vegetables and fruits jugoscuidadosamente selected.
(5) Less Salt and Sodium: Patients with chronic renal failure with hypertension and edema, limiting sodium and sodium-rich foods, if necessary, without salt diet. By using diuretics or accompanied by vomiting, diarrhea, should not limit sodium.
(6) The provision of high quality protein: uremic patients, protein minimum daily requirement 0.5g / kg body weight between quality protein accounted for over 50%, the only way to maintain the physiological functions of the organs of body. When renal function in patients with early and stages stockings damage, ie, the glomerular filtration rate (GFR)> 25 ml / minute, the daily intake of protein per kilogram body weight of about 0.6 more appropriate grams, but you must replace the calories.
In recent years, additional essential amino acids and preparations preparations α-keto acids were also expressed. But such preparations higher prices, limiting their use. At low protein diet, mainly high quality protein such as milk, eggs, fish and lean meat, energy intake should be sufficient.
