Table 2.

Characteristics of a diet enriched in fruits and vegetables that minimize hyperkalemia

Carbohydrate load causing stimulation of insulin release and shift of potassium into cells
Increased alkali content
 Shift of potassium into cells
 Increased potassium secretion brought about by pH effect on renal outer medullary potassium channel (ROMK) in collecting duct
High fiber content
 Increased stool bulk and less potassium absorption
 Decreased constipation
 Possibly increased kidney potassium secretion via gastric-kidney crosstalk
 Possibly increased colonic potassium secretion
Lack of exogenous administration of potassium for flavoring, unlike meat products
