This literature review analyzed ten articles investigating the effects of low dietary sodium intake on neurohormonal and fluid overload on heart failure (HF).Recommendations for low dietary sodium to HF patients has been debated in the past one to two decades.This report presents a literature review of interventional studies from 2006 to 2015 investigating adult HF patients.The results of the neurohormonal outcome variables seem to be the primary consideration for recommending a low sodium diet to patients with HF. Most of articles in this review reported that 2.6–3 g/day of dietary sodium is effective for decreased BNP, renin, and aldosterone (neurohormonal) plasma levels in patients with HF.We have to provide the reason, effect, and amount of dietary sodium when providing dietary sodium recommendations to patients.
