Why Do People on Dialysis Need Low-Phosphorous Diet?




If you are on dialysis, you need to follow low-phosphorous diet. But do you know why you need to limit phosphorous intake? What if you ingest large amounts of phosphorous every day?
We know only when our kidneys are failed in displaying kidney functions, can dialysis be needed. Our kidneys have many functions one of them is excretion function. Through excretion function, our kidneys help us excrete the excessive phosphorous. However, for people who are undergoing dialysis, their kidneys have lost this function, so the phosphorous level in their blood is easy to be elevated. High levels of phosphorous threaten our life seriously; so to avoid this bad consequence, limiting daily phosphorous intake is very important.
Because of failed kidney, phosphorous accumulates in the blood, phosphorous level in the blood increases therewith. High level of phosphorous causes hyperphosphoremia easily, which is one of the leading risk factors for renal osteodystrophy, hyperparathyroidism and many other serious vascular diseases.
To reduce the phosphorous level in the blood, people on dialysis should avoid eating foods which are high in phosphorous such as banana, pumpkin, squash, watermelon seeds, sunflower seeds, toasted wheat germ, cheese, sesame seeds, tahini, nuts roasted soybeans, flax seeds and bacon. All these foods are rich in phosphorous, so people on dialysis should avoid eating too much of them.
