Interrelations between the physiology of sodium, potassium and water, and nutrition.
Journal of human nutrition
The relationships between altered nutrition and body composition of sodium, potassium and water are reviewed. The physiological mechanisms involved in cellular homeostasis of sodium and potassium are also discussed with particular reference to energy costs. Alterations in mineral metabolism in protein energy malnutrition, oedema, potassium adaptation, fasting and hypertension are described.
