Story at-a-glance

• Salt is an essential nutrient required for blood pressure regulation, transportation of nutrients into and out of your cells, ion exchange, and brain-muscle communication.
• Decades of scientific research have failed to show the benefits of a low-salt diet, and in fact tend to show the opposite. Low-salt diets are associated with higher cardiac risk across multiple studies.
• All salts are not equal, in terms of their impact on your health. Processed (table) salt is health harming, while natural unprocessed salt is not only healing, but in fact essential for many biological functions
