Minerals in our body- by Roxy

Unlike Vitamins contain carbon, minerals are inorganic elements without carbon. They are generally divided into two parts: Major minerals (>100mg/day) and trace Minerals (<100mg/day).  Both trace and major minerals are essential for our body functions, like maintain water balance, enhance body growth or cofactors to assist enzymes. etc. We typically intake minerals from foods we eat, especially minerals in plants that absorbed form soil and water.
Below i am going to list some macrominerals, as well as how each one affects your health and how can you get them from foods.

Major minerals
Calcium (Ca)
Calcium is probably the most famous minerals. It's essential for bone and teeth synthesis since you will find 99% of calcium there. It's also important for nerve transition and muscle contraction. It usually present in dairy foods. However, you also can get calcium from kale, cabbage, and broccoli. In fact, the oxalic acid in greens can bind with calcium and increase the absorption of calcium.
Sodium (Na)
Sodium is another major mineral that is an electrolyte which is used for maintaining the volume of fluid outside cells and controls muscle contraction and nerve transmission. It also helps absorption of glucose and amino acids in small intestine. It's usually high in processed foods like can foods.
Chloride (Cl)
Almost all comes from table salt(NaCl) or salt from processed food so much people eat extra amount of Cl. It's functions include maintain Acid-base balance and extracellular fluid volume in body, aids in nerve transmission.  It also a component of stomach acid.
Potassium (K)
Potassium is a major minerals that is also an electrolytes. It has similiar function with Na- that is maintain the volumn of fluid inside the cells. High potassium decrease calcium excretion and increase extra sodium excretion. Plant-base foods are rich in potassium. Potassium is usually associate with lower blood pressure so lack of potassium will lead to high blood pressure.
