Potassium and sodium work together

Potassium is an abundant, essential element needed by your muscles, blood vessels, glandular and nervous systems. Potassium and sodium are the key two body electrolytes that work together to maintain the pH of your blood. The sodium / potassium ratio is a long-term determinant of heart, blood vessel, bone, muscle, and kidney health, and the risk of death and overall health and longevity. (1, 2, 3, 4, 5)

A diet high in sugars, refined carbohydrates, processed foods and proteins is likely to be high in sodium, whereas a diet high in vegetables and other plants is high in potassium. Simply eat more vegetables (and some fruits) and less sweet, processed and pre-prepared food to normalise this ratio.

Sodium and potassium are the key pair of electrolytes. Sodium is held more tightly than potassium. The key synergy ratio is one part sodium to two parts potassium. People on a Standard American Diet are often so potassium-deficient that this ratio is in reverse.

The required dietary intake from food for an adult is 2,300 mg sodium per day, and 4,700 mg potassium.

The sodium-potassium pump is the key process which maintains body electrolytes. Potassium is more quickly taken up and more quickly excreted through the kidneys to maintain the 1:2 crucial balance between the two elements.

Low levels of potassium cause the retention of sodium. (5)

The standard medical advice for someone with a high level of sodium is a low salt diet. This actually makes the symptoms worse, starting with feeling tired and having low energy when starting a low salt diet. On a low salt diet the patient will be deficient in both sodium and potassium, as well as the Na/K ratio being lower than 1:2.
