How to control protein intake in patients with diabetic nephropathy?2017-11-17 17:37
When diabetic nephropathy develops into end-stage renal disease, protein restriction should be more stringent. Part of the wheat starch diet was used as the main source of heat, instead of rice and flour. Because the rice and flour and other staple foods contain a large number of non high-quality vegetable protein, and wheat starch in plant protein content is very small. But because wheat starch production is not easy, so can also be used in the current market sales of corn flour to replace. This can save the amount of vegetable protein, supplemented by animal protein, which is more conducive to meet the physiological needs of the body.
Amino acid supply: as much as possible intake of essential amino acids, can also take oral alpha keto acid to replace part of the necessary amino acids; or with renal amino acid supplement.
Heat: in low protein diet, the heat supply must be sufficient to maintain normal physiological needs. A daily intake of 30-35 kcal / kg of body heat. You can choose some staple foods high in calories and low protein content, such as potatoes, lotus root starch, vermicelli, taro, sweet potato, yam, pumpkin, water chestnut powder, water chestnut powder, total calorie intake reached the standard range. Ensuring supply and demand balance.
Fat: end-stage renal disease is often associated with lipid metabolism disorders, still adhere to low fat intake. Olive oil and peanut oil contain abundant monounsaturated fatty acids, which can also be used as sources of energy.
Limit salt: end-stage renal disease develops to a certain stage, often can appear hypertension, manifested as edema or urine volume reduction, limiting salt can effectively prevent the progress of complications. However, if accompanied by vomiting and diarrhea, the sodium salt should not be excessively restricted, and should be properly supplemented if necessary.
Water: it is also important to master the balance of fluids in patients.
Potassium: if the daily urine volume is greater than 1000 ml and the amount of blood potassium is normal, there is no need to limit the intake of the bell, generally can choose to eat vegetables and fruits at random.
Calcium and phosphorus: when the kidney is damaged, the excretion of phosphorus will decrease, leading to elevated blood phosphorus. Moreover, the synthesis ability of vitamin D3 decreases and affects the absorption of calcium. Calcium levels in the blood decreased, prone to osteoporosis, so the ideal treatment diet should increase calcium content, as much as possible to reduce phosphorus content. The low protein diet itself reduces the phosphorus intake, is conducive to treatment.
In conclusion, the present study has proved that low protein, low cholesterol and unsaturated fatty acid diet is very important for the protection of renal function, especially in the early stage of diabetic nephropathy should pay attention to diet therapy.
