Cutting Sodium Intake Lowers Blood Pressure at the Population Level

What Happened

WHO recommends adults consume less than 2g of sodium per day, based on evidence that excess sodium intake raises blood pressure and contributes to an estimated 30% of hypertension cases. WHO considers population-level salt reduction one of the most cost-effective public health interventions available.

Why It Matters

WHO calling population-level salt reduction one of the most cost-effective public health interventions available is a striking claim precisely because it requires no new technology — just reformulation of foods that already exist.

About 30% of hypertension, traced back to one ingredient most reformulation targets first.

FET's Takeaway

Most dietary sodium comes from processed and restaurant food, not the salt shaker at home — which is why product-level reformulation targets move this number more than consumer education campaigns do.
