A large host of countries including the United States, Canada and others throughout the European Union have all initiated programs to begin reducing the average citizen’s intake of salt. For years, research studies have published data to suggest that reducing salt intake can lead to many health benefits including lowering blood pressure and improving cardiovascular health.
A recent extensive meta-analysis led by Dr. Graudal from Copenhagen University Hospital has put forth evidence to suggest that such reductions in dietary salt intake may not be as beneficial as we currently believe. Dr. Graudal and his team of experts reviewed 167 published articles in this area and looked at the effect of reducing salt intake both on blood pressure and different blood parameters.
The review demonstrated that reducing salt intake resulted in reductions in blood pressure of less than 1% in individuals with normal blood pressure. In addition, however, it was also discovered that there are also increases in blood parameters that are associated both with increasing blood pressure and increasing risk for cardiovascular disease (including cholesterol, triglycerides, stress hormones, and renin).
Despite these conflicting reports as to the effect of salt intake on overall health, the effects of reducing dietary salt on blood pressure remain consistent. Arguably, the current guidelines for reducing salt may be too extreme and could lead to potentially harmful effects if there is not enough salt in the diet. Although some individuals would benefit from reducing salt intake, the goal for overall health should be consumption in moderation.
