Abstract
There are data demonstrating that ingestion of potassium-rich foods reduces the incidence of stroke, hypertension, nephrolithiasis, and osteoporosis. Dietary-consumption data indicate Westernized diets are high in processed foods, high in sodium content, and low in potassium. In fact, there are data suggesting individuals are not consuming enough potassium in their diet. Although consumption of diets high in plant proteins, fruits, and vegetables—which are excellent sources of potassium—is recognized as healthy and beneficial, individuals with decrements in their kidney function have been advised to avoid these foods. In reviewing the literature that provides the rationale for potassium restriction in patients with reductions in kidney function, it appears there is little direct evidence to support the levels of restriction which are now prescribed. Additionally, there are two new potassium-binding agents which are well tolerated and have been documented to be effective in controlling serum potassium. Therefore, with the new binding agents and the lack of empirical evidence supporting the stringent dietary potassium restrictions, the authors conclude by indicating the pressing need for further research focusing on dietary liberalization of potassium in patients with reductions in kidney function to enhance overall health and well being, to provide them cardiovascular benefits, and to reduce overall risk of mortality through the incorporation of potassium-enriched foods.
