Potassium content is higher is younger plant tissues, so some plant material in a daily diet should be from younger tissues. A easy remedy is sprouts that have been nurished in a potassium rich nutrient media. Adrenal hormones favor sodium retention and potassium loss, so stress can affect potassium levels. Reducing stress levels could increase body potassium. In the body, potassium salts dissociate to yield potassium as a free cation or positively charged electrolyte, which must be balanced by an anion.
Sodium is major extracellular cation and potassium is the major intracellular cation.
Potassium also important to transmission of nerve impulses. Diets of grains and soybean normally maintain enough potassium to meet requirements for swine and poultry. Mature pastures that have weathered or exposed to rain have less potassium.
