Potassium - technical card
POTASSIUM: WHAT IS IT?
Potassium is the main intracellular cation, essential because it isn’t replaceable by other elements. A man weighing 70 kg contains about 140 g. of potassium, 95% of whom are located in cells. The rest is in the extracellular fluid, in a concentration of 3,3-5,5 mEq (137-215 mg/l). One milliequivalent of potassium (mEq.) corresponds to 39 mg.
FOR WHAT IS IT USEFUL?
Potassium plays an essential role in the body and is involved in many vital functions. It adjusts the water content of the cells and regulates the osmotic pressure. Along with sodium and chlorine ir regulates the cellular acid-base equilibrium: in metabolic acidosis, potassium exits from the cell, while the opposite occurs in alkalosis. In equilibrium with calcium and magnesium, helps to regulate the main cellular functions and especially the excitability of muscles, heart and nervous system.
Is essential to the myocardium, on which exerts a direct action. Activates the enzymatic systems intervening in the formation of protein. Involved in glycogen synthesis and thus in energy production.
HOW IS IT TAKEN?
Potassium, which is an essential constituent of all living cells, is contained in all foods. The richest dietary sources of potassium are fresh foods not undergoing to conservation treatments such as fruit, vegetables and fresh meat.
:: 100 g. of fresh vegetables contain 200-400 mg. Potassium
:: 100 g. fresh fruits contain 100-200 mg. Potassium
:: 100 g. bananas contains 380 mg. Potassium
:: 100 g. chocolate contains 420 mg. Potassium
:: 1 liter of wine contains 1040 mg. Potassium
:: 1 liter of Coca-Cola contains 520 mg. Potassium
