The world’s fifth largest country announced regulations limiting the amount of artificial trans fat in the Brazilian food supply. Implementation will begin on July 1, 2021 and will culminate in a complete ban of partially hydrogenated oils effective January 1, 2023, in line with WHO’s target for global trans fat elimination. With support from our partner GHAI, the Brazilian Association of Nutrition (Asbran) built a strong coalition of advocates, engaged political decision-makers, and leveraged media to create a sense of urgency around the need for trans fat elimination.
