    It has been known for decades that urinary potassium excretion varies with a circadian pattern. In this review, we consider the historical evidence for this phenomenon and present an overview of recent developments in the field. Extensive evidence from the latter part of the last century clearly demonstrates that circadian potassium excretion does not depend… Read Abstract

  • Semin Nephrol.. 2013 May Potassium in hypertension and cardiovascular disease.

    The increased prevalence of hypertension and cardiovascular disease in industrialized societies undoubtedly is associated with the modern high-sodium/low-potassium diet. Extensive experimental and clinical data strongly link potassium intake to cardiovascular outcome. Most studies suggest that the sodium-to-potassium intake ratio is a better predictor of cardiovascular outcome than either nutrient individually. A high-sodium/low-potassium environment results in… Read Abstract
