Banning One Poison Just Swaps It for Another

A study dropped last week showing that sodium benzoate, potassium sorbate, and a dozen other preservatives linked to cardiovascular risk.

The research tracked thousands of people across years and found correlations between consumption of these chemicals and high blood pressure. Then the usual machinery engaged—headlines, concern, the slow bureaucratic interest of regulators in Europe.

The story everyone wants to tell is that we're finally catching a culprit. The story no one is telling is what happens next.

In 1958, the FDA banned cyclamate as an artificial sweetener after a rat study suggested it might cause cancer. The chemical had been in diet sodas for six years. The ban was swift and the assumption moral—we were protecting people from poison. What actually happened was less noble. The industry didn't reformulate toward less processed food—it switched to saccharin, which arrived with even less safety data. Saccharin was already grandfathered into the food supply and nobody had to prove it was safe.

We create the appearance of progress while actually increasing total chemical exposure because we've now got the old suspect plus the new substitute, neither fully understood.

We didn't eliminate chemical sweeteners. We swapped an unknown for another unknown, then spent the next two decades arguing about whether saccharin was carcinogenic while people drank both in sequence. The mechanism repeats because the incentive structure doesn't change. When a preservative gets flagged by epidemiological association—correlation, not causation, not mechanism—regulators respond to public pressure by restricting it. The food industry doesn't suddenly embrace shelf life as a constraint.

It has spent seventy years optimizing logistics around the ability to ship a chicken nugget across a continent for six months. That infrastructure doesn't evaporate. Instead, manufacturers reach for the next preservative on the approved list, often one studied less rigorously because it wasn't controversial enough to scrutinize. We create the appearance of progress while actually increasing total chemical exposure because we've now got the old suspect plus the new substitute, neither fully understood.

The real question isn't whether sodium benzoate is bad. It's whether we'll pretend the replacement is better simply because it's different. History suggests we will.
