Dietary Salt Intake and Hypertension

Over the past century, salt has been the subject of intense scientific research related to blood pressure elevation and cardiovascular mortalities. Moderate reduction of dietary salt intake is generally an effective measure to reduce blood pressure. However, recently some in the academic society and lay media dispute the benefits of salt restriction, pointing to inconsistent outcomes noted in s...

Dietary salt intake, salt sensitivity, and cardiovascular health.

The controversial issue of the relationship between dietary NaCl (referred to as “salt” in this article) intake and health was framed nicely in the superb review by Prof Eberhard Ritz.1 When salt was not readily available, it was a relatively essential commodity, but in the modern world salt has become plentiful, and it is actually difficult to achieve a low salt intake without exerting a signi...

How to Reduce Dietary Salt Intake

Hypertension is the single largest risk factor for multiple comorbidities, including stroke, myocardial infarction, and chronic kidney disease, and is projected to be the leading global cause of death and disability by 2020. A major risk factor for hypertension is high dietary salt intake. The salt sensitivity of blood pressure, an exaggerated pressor response to salt intake, affects ≈50% of hy...

Vascular consequences of dietary salt intake.

Animal and human studies support an untoward effect of excess dietary NaCl (salt) intake on cardiovascular and renal function and life span. Recent work has promoted the concept that the endothelium, in particular, reacts to changes in dietary salt intake through a complex series of events that are independent of blood pressure and the renin-angiotensin-aldosterone axis. The cellular signaling ...
