Abstract
Sixty-nine normotensive volunteers participated in an eight-week study to test the feasibility and acceptability of two low-sodium (less than 70 mEq), high-potassium (greater than 100 mEq) diets. The diet groups differed only in the use of KCl 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.
