After calcium, phosphorus is the second most abundant mineral present in human body. These two nutrients work together to build and maintain strong bones and teeth. Besides this, phosphorus is needed for proper kidney, heart and brain function.
Phosphorus deficiency is rare, but when it happens, most significant symptoms are weak bones and joint pain. Sometimes, this deficiency can lead to conditions such as osteoporosis and anorexia.
Food rich in protein, such as meat, poultry, fish, eggs and dairy products are good source of phosphorus.
