Is it Possible for Salt to Reduce Your Blood Pressure?

Overview

Salt and hypertension have been associated in the public consciousness for many years, with doctors advising patients to reduce salt intake. However, recent evidence suggests that lowering salt consumption may not be the best approach for individuals with normal blood pressure and even those with high blood pressure. Research presented at a conference and outlined in a new book by a cardiovascular research scientist indicates that restricting salt could have adverse effects on health. These findings challenge the conventional wisdom around salt intake and blood pressure regulation.

Salt up – blood pressure down

A study conducted by Boston University School of Medicine followed a group of 2,632 individuals with normal blood pressure over 16 years. The research revealed that blood pressure levels increased as salt intake decreased, contradicting the widely held belief that reducing salt helps lower blood pressure. Dr. Lynn Moore, an associate professor of medicine, presented these findings at a conference, emphasizing that higher sodium intakes may not be harmful for generally healthy individuals. The study suggested that consuming foods rich in potassium, magnesium, and calcium is more effective in reducing blood pressure than solely focusing on salt reduction.

It’s all a myth

Dr. James diNicolantonio, a researcher at Saint Luke’s Mid America Heart Institute, challenges the notion that salt restriction is beneficial. In his book, "The Salt Fix," he debunks the long-standing belief that salt is harmful, highlighting that restricting salt may have negative consequences. DiNicolantonio traces the origins of the salt-blood pressure myth to flawed research from the past, emphasizing that for most people, salt intake does not significantly impact blood pressure. He suggests that cutting back on salt may not be necessary for individuals without high blood pressure.

The Korean paradox

Dr. diNicolantonio points out the "Korean Paradox," where populations with high salt diets, such as the Japanese, French, and Koreans, have low rates of cardiovascular disease. He lists potential negative outcomes of low salt intake and argues that a moderate salt intake range of 3 to 6 grams per day is optimal for health.
