Phosphorus and sulfur are also common essential elements, essential to the structure of nucleic acids and amino acids, respectively. Chlorine, potassium, magnesium, calcium and phosphorus have important roles due to their ready ionization and utility in regulating membrane activity and osmotic potential. [2]
Osteophagy in humans would be considered a form of pica. Unlike calcium and phosphorus in most animals, pica is associated with iron deficiencies in humans. [21] Humans are unlikely to suffer from calcium and phosphorus deficiencies because the minerals are widely abundant in the foods they consume. [22]
Phosphorus occurs in amounts of about 2/3 of calcium, and makes up about 1% of a person's body weight. [10] The other major minerals (potassium, sodium, chlorine, sulfur and magnesium) make up only about 0.85% of the weight of the body. Together these eleven chemical elements (H, C, N, O, Ca, P, K, Na, Cl, S, Mg) make up 99.85% of the body.
The main food sources for phosphorus are the same as those containing protein, although proteins do not contain phosphorus. For example, milk, meat, and soya typically also have phosphorus. As a rule, if a diet has sufficient protein and calcium, the amount of phosphorus is probably sufficient. [141]
Without phosphorus, plants and animals couldn't function, so I find it troubling to read that production of the element is projected to peak in 2035, and that we are already experiencing market ...
Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry , which produces food through intensive agriculture and distributes it through complex food processing and food distribution systems.
Poor management of phosphorus is leading to water pollution and food shortages, with farmers struggling to afford some fertilisers for their crops. Call to tackle phosphorus impact on food and ...
People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
