Excess sodium is the leading dietary risk factor for death globally, yet fewer than 1 in 5,000 Americans meet recommended sodium and potassium guidelines. Dr. Michael Greger examines potassium chloride salt substitutes as a solution to this dual problem. Multiple randomized controlled trials show that replacing regular salt with potassium chloride significantly reduces blood pressure and cardiovascular disease risk. One study found that using a 50/50 blend reduced cardiovascular death risk by 40% and extended life expectancy by nearly a year, equivalent to making people 14 years younger in terms of mortality risk. These substitutes work because they simultaneously reduce harmful sodium while increasing beneficial potassium intake, addressing both sides of our evolutionary mismatch with modern processed foods.
