Mexico’s type 2 diabetes crisis, with a prevalence of 16·9%, has made the country a focal point for fiscal policies targeting non-communicable diseases (NCDs).

These measures, driven by evidence linking ultra-processed foods and SSBs to obesity and type 2 diabetes, are expected to substantially reduce consumption, but pragmatic challenges remain.
