Is sodium an old enemy or a new friend? 을지대학병원 신장내과 방기태

A meta-analysis of data from randomized, controlled trials (RCTs) has demonstrated we do not currently have strong evidence to indicate that there is a beneficial effect of salt restriction on mortality It might, in fact, increase the risk of all-cause mortality in patients with heart failure (HF).

“to reduce their dietary salt intake shows a beneficial effect in the short term (up to 3 years) in reducing blood pressure by a small amount (1–4 mmHg), but no strong evidence of a reduction in deaths,” currently available RCTs are still not good enough ... for any conclusion on the general health impact of salt reduction.”

Objective: To assess whether 24-hour urinary sodium excretion predicts blood pressure(BP) and health outcomes. Participants : 3681 participants without CVD

the study as being small with low event rates and relatively young participants. unreliable measurement of sodium intake failure to account for key factors that influence sodium intake and heart disease risk, and missing or incomplete urine data

A DASH OF DATA IN THE SALT DEBATE Science (New York, N.Y.) [Science] 2000 May 26; Vol. 288 (5470), pp. 1319. DASH-Sodium David McCarron**, of the Oregon Health Sciences University in Portland, for those with normal blood pressure eating the healthy DASH diet, reducing salt from 8 grams to 4 grams a day made little difference in blood pressure (1.7/1.1 mmHg). If you are eating the healthy DASH diet and you have normal blood pressure, sodium restriction has almost no effect.

Professor Fujita until we have more-robust data, “we should not change [recommendations for] salt restriction to less than 6 g per day as a life-style modification in hypertension guidelines.”
