Buckwheat is good for the kidneys

Carbohydrates for energy supply!
Despite a sufficient energetic supply of 30 to 35 kcal / kg body weight daily, there is often too little carbohydrate content and too little fiber in the case of kidney failure and too much fat in the diet. By choosing appropriate carbohydrate and fiber sources, the progression of the decline can kidney function may be slowed down.

Daily example:
With 1800 kcal daily, 900 kcal or 225 g carbohydrates and 30 g to 40 g fiber should be consumed. This is achieved on a fictional day by:
  • 2 slices of rye bread + 30 g quark + 2 teaspoons of jam
  • 75 g plain rice + 150 g green beans + 1 vegetable onion
  • 75 g millet + 100 g red pepper + 100 g yellow pepper
  • 150 g pear fresh + 150 g apple fresh

The above foods together contain 1050 kcal, 35 g protein, 212 g carbohydrates, 32 g fiber, 1585 mg potassium and 663 mg phosphate.

A basic diet structured in this way, which of course has to be supplemented with the appropriate amount of protein and high-quality fats, corresponds, for example, to the requirements for a diet in case of renal insufficiency.

Suggested quantities:

In which amounts should which sources of carbohydrates be consumed and how do you achieve variety? Here, too, the variation in diet is very important.  

Bread up to 150 g (about 3 slices) per day
Gray, mixed, rye, wheat bread, wholemeal wheat toast, wholegrain rusks, pumpernickel without acidification, wholegrain bread without acidification  

Fruit 250 g per day
In the case of increased blood potassium values, note the potassium content if necessary  

Cereal products according to the energy requirementf
Whole wheat noodles, durum wheat noodles, plain rice, millet, buckwheat, buckwheat groats, barley barley corn flour, corn grits, whole grain flakes, corn flakes, cous-cous, wheat flour, poured wheat, whole wheat flour, rye flour, rye whole grain flour, oat flakes, oat flour

Danger!If the potassium level in the blood is high, whole grains must be boiled in plenty of water and the water discarded. If this is not possible during the preparation of the food, consumption may have to be restricted. This applies in particular to whole wheat flour, whole rye flour, spelled flour, green kernels
Danger!Never use pure bran or products enriched with bran!

Other in addition to grain products
Batat (sweet potato), peas, legumes, potatoes, Tobinambur, sweet corn
Danger!If the blood potassium level is elevated, it may be necessary to use a low-potassium preparation.
If the blood phosphate level is high, peas, pulses and sweet corn should only be consumed in small portions.

Dietary fiber: Why should fiber not be forgotten, especially in the case of kidney failure?
Since dietary fiber in the intestinal tract contributes to an increased excretion of protein breakdown products, an intake between 30 g and 40 g is recommended.

Which fiber suppliers are problematic?
The intake is complicated by the fact that the dietary fiber from the carbohydrate carriers whole grain cereals and legumes are relatively rich in phosphate and therefore cannot be used indefinitely. On the other hand, the phosphate from these products is only available to a limited extent (approx. 50%) for absorption. The latter does not apply to sourdough products, however, because the fermentative process increases the availability of phosphate.
As long as there are no elevated blood potassium levels, the fiber from fruits is harmless. The same applies to the fiber from vegetables. At this point it should be noted that the artichoke, parsnip, salsify and Jerusalem artichoke contain particularly high fiber concentrations, but also a relatively high amount of phosphate and potassium.

What special products are there?
For thickening sauces and adding fiber to flourGuar -guar (e.g. available in health food stores or health food stores). Guar-guar has been shown to have a positive effect on blood sugar levels and increases the excretion of protein breakdown products.
Same goes forIndian flea seeds and Lactulose. Both substances also improve the intestinal function and at the same time the Indian flea seeds have a positive effect on the cholesterol metabolism. However, the requirement for using the dietary fiber mentioned is a generous intake of fluids, which is important in any case in the case of renal insufficiency.
