We reviewed a decade of revealed analysis on the meals science and advertising of UPFs, after which labored with consultants in these fields to create and refine system diagrams to visualise the way it works.
These maps are known as “causal loop diagrams”, and their energy is in exhibiting reinforcing (constructive) suggestions loops that drive the system in direction of its final objective: promoting extra UPFs.

Complacency shouldn’t be an choice. The meals system wants rebalancing in order that it serves and nourishes individuals now and sooner or later.
