rich potassium foods list

Introduction

Potassium is an essential nutrient present in all body tissues. It is sometimes referred to as an electrolyte because it carries a small electrical charge that activates various cell and nerve functions.

Potassium has a strong relationship with sodium but has opposite effects on the body as high potassium intake may offset some of the sodium in the diet. [1,3,4]

  • Potassium is absorbed in the small intestine via passive diffusion. [1]
  • About 85-90% of potassium consumed is absorbed. [1,2]
  • After a meal, potassium is absorbed and rapidly enters the extracellular fluid. [5]
  • The total amount of potassium in the human body is approximately 140g (for a 175-pound adult). [1,5]
  • Also, almost 98 per cent of total body potassium is found within cells. [3,5]
  • Most of the body potassium is located in the muscle (70%), with lower amounts present in the bone, liver, skin and red blood cells. [5]
  • Potassium is usually excreted in the urine, some excreted through stool and a very small amount through sweat. [1,5]
  • The total potassium excreted through urine is estimated to be around 77% and 92% of total dietary intake. [5]

Potassium Interaction With Other Nutrients

  • Sodium chloride – Dietary potassium intake can increase urinary excretion of sodium chloride. [2]
  • MagnesiumInadequate magnesium intake can lead to potassium deficiency. [1]
  • CalciumPotassium depletion enhances the urinary loss of calcium. However, potassium supplementation can potentially decrease urinary calcium excretion. [5]
