For anybody not a secret that the human body is a veritable fount of almost all chemical elements of the periodic table. And one of the most important for us is potassium.
If you believe the authors of the textbook on chemistry for ninth grade, enough potassium is a soft silvery-white metal. It is extremely lightweight and has a very low melting point. Their activity potassium is in third place, is not found in its pure form, on the air almost instantly oxidized, as well as quickly reacts with other elements, particularly water, forming a caustic.
Depending on body mass, season, nutrition and other factors in the human body contains about 160-250 grams of potassium, and 98% of all stocks located inside the cells. And here its principal role is maintaining the normal functioning of human cells. However, for this potassium requires sodium, which is contained in the intercellular space. 2% extracellular potassium intended for muscle contractions, nerve impulse components, constancy of blood pressure. Potassium necessary for normal work of all of our soft tissues: blood vessels, capillaries, muscles and also cells of the brain, nerves, liver, kidneys.
Potassium and sodium regulate the heart rhythm and regulate water balance. Among other things this chemical element also performs the following functions: increases the supply of oxygen to the brain, acts as a catalyst in carbohydrate and protein metabolism, keeps the acid-alkaline balance, supports the excretory processes of the kidneys, increases mental activity, participates in the regulation of heart rate. Also, this element is required for stamina and physical strength.
Potassium, as a very active item – displays the body of toxins. The consumption of foods high in potassium is necessary for people suffering excess weight. For various diets the diet includes such foods.

Seaweed, dried apricots, beans, peas, prunes, almonds, hazelnuts, walnuts, potatoes are the main foods that are richest in potassium
In compiling the diet should pay attention to the foods containing potassium. But one should not forget that increasing the potassium level leads to the excretion of sodium from the body, and this leads to deterioration in the functioning of the whole organism. Need potassium and sodium were always in balance.
An overabundance of potassium affects the heart muscle that impairs the functioning of the kidneys, leads to deposition of salts of potassium, which increases the risk of urolithiasis. An excess of potassium manifests itself in unpleasant sensations in the limbs, increasing urine separation, agitation, weakness.
With the amount of potassium in the body, you have everything in order, but the style of limping on both legs? Then here's my advice — use more accessories.
