Hey sis… What’s Phosphorus??? The Lab Test…

Yesterday my sister gave me a call…. she asked me about what’s phosphorus… what does the phosphorus lab test mean… and how is it related to the diet and health….

Well… let‘s see…

Phosphorus is a mineral.

It is found in about 80% of the body’s bones and teeth. It is a component of every cell and of some important metabolites such as DNA, RNA, ATP… and phospholipids. It is also important for the body’s PH regulation.

Phosphorus in the diet is interrelated to calcium and protein intakes… Foods that are good sources of proteins are also good sources of phosphorus.
It is basically found in the following foods: cheese, egg yolk, milk, meat, fish, poultry, whole grain cereals, nuts, legumes and soft drinks. Thus, one can’t reach phosphorus inadequacy if the intakes of calcium and protein are sufficient.

If phosphorus lab tests are low (which is usually rare), that means the person is in a state of hypophosphatemia, which might be associated with hypoparathyroidism (hypoparathyroidisim is an endocrine disorder in which the parathyroid glands, glands in the neck, do not produce enough parathyroid hormone (PTH)) or it is due to decreased dietary intake.

If phosphorus lab tests are high, that means the person is in a state of hyperphosphatemia that might be related to hyperparathyroidism (hyperparathyroidism is the excessive production of parathyroid hormone (PTH) by the parathyroid glands), or it is due to renal (kidney) malfunctioning or from a low calcium high phosphorus diet consumption.

Imbalance of calcium and phosphorus ratio within the dietary intake (low ratio) can lead to the thinning of the plates within the bones, all over the skeleton, that in turn leads to fractures…

Thus, in conclusion, it is very much important to have a regulated phosphorus intake and sufficient calcium intake from food… inhibiting bone loss for the long run….
