By 2019, Chile's sweeping Food Labeling and Advertising Law, enacted in 2016 in Santiago, had produced measurable reductions in the purchase of sugary beverages and high-sugar cereals, providing the first robust evidence that front-of-package warning labels and advertising restrictions could effectively reduce junk food consumption at a national scale. The Chilean law, which required black stop-sign warnings on packaged foods exceeding specified thresholds for sugar, sodium, calories, or saturated fat, also banned junk food advertising to children and prohibited such products from being sold in schools. Research published in 2019 showed a 24 percent reduction in purchases of high-sugar beverages and significant declines in sugary cereal sales, demonstrating that regulatory approaches to junk food could achieve results that industry self-regulation had failed to deliver.

Chile's successful food regulation became a subject in contemporary Chilean poetry, where poets celebrated the law as an act of cultural self-determination against the encroachment of multinational junk food corporations. Chilean poets including Raúl Zurita's students and younger voices in the Santiago poetry scene have written about the warning labels as symbols of resistance, connecting the law to Chile's longer poetic tradition of political engagement and using food regulation as a metaphor for the possibility of collective action against seemingly invincible corporate power.
