Sodium restriction is only warranted for people with kidney failure or severe regulatory dysfunction. The kidneys reabsorb 97–98% of all filtered fluid daily, reflecting sodium's physiological essentiality. The kidneys self-correct elevated blood volume from sodium intake through pressure diuresis. Sodium only meaningfully sustains hypertension when chronic stress or exercise overrides the pressure-diuresis mechanism. Sodium is the body's primary signaling mineral; the body does not treat it as a toxin.
