Low-Sodium, High-Potassium Diet: Feasibility and Acceptability in a Normotensive Population.

Sixty-nine normotensive volunteers participated in an eight-week study to test the feasibility and acceptability of two low-sodium (<70 mEq), high-potassium (>100 mEq) diets. The diet groups differed only in the use of KCI salt substitute. Both dietary groups were able to reduce sodium and increase potassium intake compared to the control group. Urine sodium excretion decreased in the diet groups but no change was observed in potassium. Potassium chloride salt substitute was not used as recommended, suggesting its unacceptability.
