RHR: Shaking Up the Salt Myth

For decades, public health guidelines have warned that reducing sodium intake is essential for preventing high blood pressure and cardiovascular disease. But a closer look at the scientific evidence reveals a far more complex story. In this episode of Revolution Health Radio, Chris explores the history behind the low-sodium movement and examines the research that shaped modern dietary guidelines. From early animal studies to large international analyses, the data suggests sodium intake follows a J-shaped curve, where both very low and very high intakes may increase cardiovascular risk. Chris explains the essential role sodium plays in the body, how severe sodium restriction can activate hormonal stress responses, and why salt sensitivity, potassium intake, kidney function, and lifestyle factors are critical in determining the right approach.
