Excessive salt intake remains the most fatal flaw in diets, being 15 times deadlier than diets high in soda.
Replacing sodium chloride with potassium chloride in salt substitutes can effectively lower blood pressure and reduce the risk of developing hypertension.

The Need for Less Sodium and More Potassium Rich Foods
A staggering 99.99% of Americans fail to meet the recommended minimum potassium intake or stay within the maximum recommended sodium intake. Unhealthy diets shave hundreds of millions of disability-free years off lives each year. Four out of five of the deadliest dietary traps involve not consuming enough whole grains, fruits, nuts and seeds, and vegetables. Excessive salt intake remains the most fatal flaw, being 15 times deadlier than diets high in soda.
The Impact of Salt and Sodium on Health
Reducing sodium in the diet is the most effective public health action related to nutrition. High sodium intake is associated with increased disease activity in multiple sclerosis and serious inflammatory autoimmune diseases. While salt is predominantly found in processed foods, the reduction of sodium has been a challenge due to low compliance. Less than 2% of adults in the US consume the recommended daily minimum intake of potassium, leading to a high prevalence of potassium deficiency. Salt substitutes containing potassium chloride can significantly reduce blood pressure.
Potential Benefits and Safety of Salt Substitutes
Replacing sodium chloride with potassium chloride in salt substitutes can effectively lower blood pressure. Studies have shown that even a quarter of potassium salt substitution is associated with cutting the risk of developing hypertension in half. A randomized control trial revealed that substituting regular salt with potassium chloride reduced the risk of dying from cardiovascular disease. Concerns about salt substitutes primarily revolve around certain populations with impaired kidney function, as excessive potassium intake can be problematic. Monitoring kidney function is crucial to ensure safety.
