Phosphorus is a mineral element that, together with calcium and vitamin D, is responsible for he althy and strong bones. Moreover, it is essential for the proper functioning of the nervous system. What other functions does phosphorus play in the body? What products are rich in this element? What are the consumption standards for phosphorus?

Phosphorusis a mineral element necessary for the proper functioning of the body. First of all, it is responsible for he althy and strong bones and teeth, but it also performs many other important functions in the body.

Phosphorus - role in the body

Phosphorus in the highest amounts (about 85%) is found in bones and teeth, therefore (together with calcium) it takes part in their mineralization, and thus is responsible for keeping them he althy and strong. The rest of this component is found in soft tissues and cell membranes, the structure of which also requires its presence.

In addition, phosphorus can be found in nucleic acids (DNA, RNA) that make up the genetic code, and therefore it is an important carrier of genetic information. This element also participates in the conduction of nerve stimuli, is involved in energy transformations and helps to maintain the acid-base balance in the body.

Phosphorus - deficiency symptoms and symptoms

Phosphorus is commonly found in food, therefore it is generally not deficient in the body. The deficiency of this element can occur in people who are malnourished, with malabsorption disorders, alcoholics, parenteral nutrition and long-term treatment of hyperacidity with aluminum hydroxide, which creates compounds with phosphorus that are not absorbed in the gastrointestinal tract.

This leads to weakening of muscles and bones, and even to osteomalacia, i.e. bone softening (also known as adult rickets). In addition, the body becomes less resistant to diseases.

The symptoms of phosphorus deficiency are weakness, muscle pain, bone pain, vomiting, breathing disorders and nervous system disorders, e.g. paralysis, paresthesia, disturbance of consciousness, confusion, nausea, convulsions.

It is worth knowing that the absorption of phosphorus is much lower in grain products or legumes. Toincrease the absorption of phosphorus from these products, apply their appropriate treatment, e.g. soak the seeds of legumes in water before cooking or ferment the dough in the production of bread.

Phosphorus - who has an increased demand?

Increased demand for this element occurs primarily in children and adolescents (due to the period of intensive growth).

Phosphorus - the effects and symptoms of excess

An excess of phosphorus in the body can occur not only as a result of its excessive consumption (from food or in the form of supplements), but also as a result of kidney failure or the release of phosphorus from bones and cells. There are no data on chronic poisoning with forms of phosphorus found in food.

The data from the Food and Nutrition Institute shows only that with high phosphorus consumption, soft tissue calcification and an increase in bone porosity may occur, although some scientists argue that excess phosphate in the diet can cause hyperactivity, autism and even schizophrenia in children.

In addition, excess phosphorus may reduce the absorption of other minerals, such as zinc, magnesium, iron, copper and calcium. Remember that phosphorus improves calcium absorption, as long as the amount of phosphorus in your diet is close to the amount of calcium.

If there is too much phosphorus, it causes leaching of calcium from the bones. It is worth knowing that vitamin D supports the absorption of phosphorus and calcium and in maintaining the balance between these two elements.

The symptoms of excess phosphorus in the body are diarrhea, nausea and vomiting.

Phosphorus - products containing phosphorus

A particularly rich source of phosphorus are rennet cheeses, buckwheat, canned fish and smoked fish eaten with bones. There is also no shortage of it in offal, meat, dark bread and eggs.

It's good to know thatphosphorus in the form of phosphates (symbol E451 or E452) is used in food processing, e.g. processed cheese, some cold cuts, pastry, coca-cola drinks, bread, sausages, cheese, milk desserts, sweet breakfast cereals, yoghurts fruit, etc. Phosphates play the role of, inter alia, stabilizers and acidity regulators, as well as emulsifiers and antioxidants.
