Study suggests food warning labels, restricted sales may help reduce childhood obesity rates

A study in Chile found that food warning labels and restricted sales/marketing to children reduced childhood obesity risk by 2.9% in girls and 2.4% in boys within 18 months of a 2016 law. The policy targeted foods high in sugar, saturated fat, salt, or calories, and further phases with stricter limits were implemented in 2018 and 2019.
