Phosphorus is a highly abundant mineral that is found primarily in the teeth and bones as well as all the cells and tissues in the body. Meat and dairy products are the best food sources to supply ample amounts of phosphorus.
Primarily used in forming the teeth and bones in the body, it also aids in filtering out waste via the kidneys. Phosphorus is involved in the process of carbohydrate and fat utilization for energy as well as synthesizing proteins for cellular/tissue growth, maintenance, and repair.
Phosphorus is also known to assist in muscular contraction, maintaining a regular heartbeat, and nerve function. It will also regulate and balance other vitamins and minerals like vitamin D, iodine, magnesium, and zinc.
Sources of phosphorus
The primary source of phosphorus are meats and milk. A general rule of thought associated with phosphorus consumption is that if the food contains protein and calcium, it will contain phosphorus. Legumes, eggs, and nuts are also decent sources of phosphorus.
Whole-grain breads and cereals will claim to contain more phosphorus than their non-whole-grain counterparts but this is a bit misleading. Phosphorus is stored in the form of phytin within whole-grains and that is not able to be digested by humans. Fruits and vegetables contain small amounts of phosphorus.
Set forth by the Institute of Medicine, the recommended dietary allowances for phosphorus are below (some individuals may be placed on a plan that requires higher than normal amounts to manage a specific issue they may be experiencing).
|Table 1: Recommended Dietary Allowances for Phosphorus1|
|Pregnant or Nursing Females under 18 years||1250mg/day|
|Pregnant or Nursing Females 18+ years||700mg/day|
