Salt

The podcast *Maintenance Phase* dismantles the myth that salt is universally dangerous, revealing that the public health campaign to reduce sodium intake was built on shaky science, flawed studies, and powerful industry lobbying. The hosts expose how the 'salt hypertension hypothesis'—the idea that salt causes high blood pressure—gained traction not through robust evidence, but through early animal studies, a single influential global study (Intersalt), and a political climate eager for simple dietary fixes. They reveal that most salt in our diets comes from processed foods, not the shaker at the table, and that many people don’t even respond to salt with higher blood pressure. In fact, some people see their blood pressure rise when they cut salt. The episode exposes the Salt Institute—a lobbying group with ties to far-right political movements—as a key player in sowing doubt about sodium guidelines. Despite decades of recommendations, adherence is abysmal, and more effective treatments like statins and SGLT2 inhibitors now exist. The truth? It’s not one-size-fits-all: some people benefit from reducing salt, others need more, and the real problem lies in a food system that’s engineered to be hyper-salty. The solution isn’t personal willpower—it’s systemic reform. The episode delivers a radical reframing: salt isn’t the enemy. The real villain is a food industry that profits from hidden sodium and a public health system that oversimplified a complex issue.
