Does reduced sodium intake improve blood pressure and metabolic variables?
The findings do not support a general recommendation for sodium restriction, suggesting it should be limited to supplementary treatment in hypertension until trials with hard clinical endpoints are conducted.
These results do not support a general recommendation to reduce sodium intake. Reduced sodium intake may be used as a supplementary treatment in hypertension. Further long-term studies of the effects of high reduction of sodium intake on blood pressure and metabolic variables may clarify the disagreements as to the role of reduced sodium intake, but ideally trials with hard end points such as morbidity and survival should end the controversy.
