According to the National Institutes of Health, minerals are essential for proper functioning of the human body. Minerals play a role in metabolism and functioning of body cells, tissues and organs. They are important for functions such as breathing, blood circulation, nutrient digestion, waste elimination, and temperature regulation. Minerals may be obtained in supplemental form or through dietary sources. There are several minerals that play critical roles in the human body. Although they are only three of many essential body minerals, it is important to understand the roles of phosphorus, potassium and calcium for a healthy body.
Phosphorous
According to the Linus Pauling Institute, phosphorous is an essential mineral that is needed by every cell for normal body function. Phosphorous is a major component of bone and helps provide bone strength and support. In addition, it helps support energy production and support in the body. A deficiency in this mineral may lead to anemia, muscle weakness, osteomalacia, rickets, bone pain, and loss of appetite. In severe cases, a deficiency may lead to death. Supplements are available. However, phosphorous is widespread in food sources including milk, cheese, yogurt, eggs, beef, almonds and peanuts.
Calcium
Calcium is an important mineral in the body. According to the National Institutes of Health, calcium is essential for the growth, maintenance and reproduction processes of the human body. In addition to maintaining healthy bones and teeth, calcium may prevent the onset of osteoporosis. It also plays an important role in blood clotting and maintaining a normal muscle contraction and relaxation cycle. Calcium may be consumed through supplement form or through the diet. Healthy food choices include dairy products such as milk, yogurt and cheese. Other foods rich in calcium include green leafy vegetables, beans and almonds.
Potassium
The National Institute of Health informs that potassium is an important mineral to the human body. Potassium plays a role in metabolism and body functions such as acid-base regulation, muscle and body growth, and maintenance of normal heart activity. It can be obtained through a supplement. However, many food sources are rich in this mineral including red meat, chicken and a variety of seafood such as salmon, cod, and tuna. Vegetables such as sweet potatoes, squash and broccoli are also rich in potassium. Other sources include banana, citrus fruits, and milk products.
