If the weight-reduction plan lacks phosphorus or too little phosphorus is absorbed, a number of issues occur to protect its shops and attempt to keep regular ranges: the kidneys excrete much less phosphorus in urine, the digestive tract turns into extra environment friendly at absorbing phosphorus, and the bones launch its shops of phosphorus into the blood. [1] The alternative actions happen in these organs if the physique has enough phosphorus shops.

The physique lacks an enzyme wanted to interrupt down phytic acid, in order it passes by the digestive tract it might probably bind not solely to phosphorus however different minerals like iron and zinc. Cooking, sprouting, and soaking are some meals preparation strategies that assist to interrupt down phytic acid in order that phosphorus is extra simply absorbed.

The most typical causes of deficiency are kidney issues or a situation referred to as hyperparathyroidism, by which an excessive amount of parathyroid hormone is launched that causes phosphorus to exit the physique by urine. Additionally, the overuse of aluminum-containing antacids can bind to phosphorus and improve the chance of a deficiency.

Nonetheless as a result of their starved state has decreased their means to effectively course of meals, reintroducing vitamin may cause issues.
