Advantages of Potassium and Sodium;

Food sources, intake deficit, and useful supplement of potassium and sodium;

An excess of potassium and sodium may be toxic?

    Salt minerals of potassium and sodium:

  1. Present in the blood, potassium and sodium together regulate the amount of water contained in the organism and are responsible for proper distribution in different body parts. 
  2. It is within the blood cells that the largest amount of potassium is over, while the sodium is rather in the liquid in which bathe these cells. 
  3. With potassium and sodium exchanges that occur across cell membranes, nervous system sends messages to the muscles that allow them to contract or relax.

    Potassium advantage:

  1. Potassium is essential for muscle growth and work. 
  2. Of all the minerals, it is the one most often prescribed by doctors as a dietary supplement, usually to replace potassium lost in the urine as a result of diuretic therapy.

    Sodium advantage:

  1. Sodium is necessary for the movement of water at the cellular level and maintaining blood pressure. 
  2. It is essential to the production in the stomach hydrochloric acid, which allows the digestion of food.

    Food sources of potassium and sodium:

  1. Potassium is provided by fruits and vegetables, whole grains, fish and meat. 
  2. It is also found in instant coffee and cocoa powder, but daily intakes are not significant. 
  3. Its content may decrease during the preparation of food, for loss in the cooking water. 
  4. The body easily removes excess potassium in the urine. 
  5. Most foods are naturally low in sodium, but we are used to add the form of sodium chloride salt during their preparation. 
  6. Other sources of sodium are sodium glutamate, which is used to enhance the taste of the dishes, and some treated water softener salts. 
  7. The sodium intake is much higher than our needs because the supply provides approximately ten times as necessary, but the excess is excreted in the urine.

    Deficient intake of potassium and sodium:

  1.  If deficient intake, potassium deficiency can be the cause of fatigue, muscle weakness, a slowdown of reflexes, and a dry skin. 
  2. In older people, it can become severe and lead besides the above disorders to mental confusion, cardiac arrhythmia and respiratory problems. 
  3. Sodium deficiency is rare because the mineral salt is present in the diet in developed countries. 
  4. They occur in the event of excessive elimination in body fluids due to prolonged diarrhea, vomiting, or heavy sweating. 
  5. The main symptoms are cramps, dry mouth, decreased blood pressure, nausea, and vomiting.

    A useful supplement of potassium and sodium:

  1. A complement of these minerals may be useful, in cases of excessive perspiration consecutive by heat or intense physical effort. 
  2. If you are prone to diarrhea or vomiting.

    A beneficial supplement of potassium:

  1.  A potassium supplement may be helpful, if you eat few fruits and vegetables. 
  2. If you suffer from chronic diarrhea. If you take diuretics. 
  3. Consult your doctor in this case, because some diuretics already have the property to prevent potassium loss.

    Can an excess of these minerals be toxic?

  1.  An excess of potassium can be toxic, especially for cardiac function. 
  2. This toxicity manifests itself, however, that under particular pathological situations, such as renal failure, and sometimes in the elderly. 
  3. The excess of sodium can cause high blood pressure in people sensitive to this mineral salt.

    Good combinations:

  1. Many nutritionists recommend absorbing two more potassium than sodium. 
  2. It has been shown that potassium is more effective in the presence of vitamin B6.
