First drew attention to eating habits in kidney diseases German physician F. Folgard in the early twentieth century. He suggested the use of a discharge mode in which within 2-3 days you can not consume any food or drink. This causes a significant diuresis and helps to cope with the swelling.
In the 40-ies. The twentieth century. W. Kempner suggested a diet based on rice and vegetables, where the consumption of protein and fat as much as possible limited. Menu for one day consists of compote prepared from 1, 5 kg of fruit, sugar and 100 g of boiled rice 50 g rice boiled without adding oil and salt.
Now in addition to diet to improve Kempner removal of fluid from the body uses carbohydrate fasting days with the use of products such as potatoes, melons, berries and even sugar.
When you assign a diet to improve kidney function are taken into account not only the presence of edema, but the level of blood pressure and the ability of the body to display the products of protein metabolism. If urine output with many proteins, it is necessary to increase their number in the diet, and vice versa.
Diet in renal disease is divided into a food 4-5 times per day. Fluid intake is limited to 1, 5 liters per day. Excluded from the diet of fatty meat, meat products, meats, beans, hot spices, coffee, chocolate and cocoa. Allowed white and gray bread, vegetable soups, cereals, pasta, dishes of lean fish, meat and poultry, dairy products, fruits and vegetables.
In the case of extensive edema is necessary to reduce the use of salt in the diet, or even completely abandon it, as sodium salts have the property to delay the fluid in the human body. When using diuretics to restore water balance in the body, it is necessary to supplement the diet of foods high in potassium (bananas, prunes, baked potatoes).
