Hyperphosphatemia is a common complication of chronic renal insufficiency and dialysis patients. For every increase in blood phosphorus levels by 1 mg / dl, the risk of death is increased by 26, and the risk of cardiovascular death is increased by 50. How to achieve a low phosphorus diet?
The phosphorus content of each kind of food is very different. In nutrition, phosphorus in food is pided by protein to calculate the ratio of phosphorus to protein as an index of phosphorus content in food.
If you want to keep the right amount of high quality protein intake and minimize phosphorus intake, then the ideal food is one that contains more protein and less phosphorus. In other words, choose foods that contain less phosphorus than protein. The egg white, for example, has a low phosphorus content and a high protein content, and the ratio of phosphorus to egg is only 1.4 mg / g.
Pay attention to the absorption rate of phosphorus. Most of phosphorus in hot food is organic phosphorus, and the absorption rate of phosphorus from different sources of intestinal tract is quite different, generally speaking. The absorption rate of phosphorus in animal protein and plant protein was about 50% and 30% respectively, while that in food additive was almost completely absorbed. Change processing. Some foods with high egg levels can reduce the amount of phosphorus in foods by changing the processing methods. For example, lean meat can be cut into small pieces of white water to boil and drain thoroughly or moderately squeezed to dry meat before consumption. It can reduce the phosphorus in meat significantly. Boil the food and eat it in soup. In this way, the phosphorus content of vegetables can be reduced by 51%, beans by 48% and meat by 38%.
Food additives are absolutely taboo. Food additives are widely used in our daily life. Phosphorus is the main component of food additives and preservatives, mainly various phosphate, such as disodium hydrogen phosphate, calcium hydrogen phosphate. Sodium dihydrogen phosphate, sodium tripolyphosphate and so on. These phosphorus belongs to inorganic phosphorus, can almost be absorbed by the human body, patients who need a low phosphorus diet, it is recommended that fresh food instead of processed food and all kinds of fast food. You should also polish your eyes when buying bagged food.
Although the dietary control of phosphorus is very important, we must control the intake of phosphorus on the premise of sufficient nutrition to avoid malnutrition.
