Chile's Food Law Slashes Child Obesity Risk

A comprehensive national food policy in Chile has demonstrably reduced the risk of excess weight among children, according to a study published on June 11, 2026. The Food Labelling and Advertising Law (FLAL), enacted in 2016, introduced mandatory warning labels on foods and drinks high in sugar, salt, saturated fats, or calories. It also imposed restrictions on the marketing and sale of these products, especially within schools.

Analysis of over 300,000 schoolchildren aged 4 to 6 revealed significant positive outcomes. Within 18 months of the FLAL's initial phase, girls experienced a 2.9% lower risk of being overweight or obese, while boys saw a 2.4% reduction. Researchers anticipate even greater impacts as subsequent phases of the law, implemented in 2018 and 2019 with stricter limits, are further evaluated.

These findings provide robust evidence supporting integrated strategies to combat the childhood obesity epidemic. Experts highlight that such policy packages, including warning labels and marketing bans, are effective and practical tools for policymakers worldwide. The long-term health benefits of even modest weight reductions in childhood are substantial, potentially lowering risks of diabetes, hypertension, and cardiovascular disease later in life.
