Countries like Mexico and Chile have been aggressive when it comes to forcing food manufacturers to label junk food with clear warnings about health-related factors such as high sugar content. The goal of the labels is to fight obesity in countries where people are consuming a lot of sugar (“Mexicans drink on average more than 44 gallons of soda a year per person.”). According to the NYT, one of the key US administration goals in the Nafta negotiations is to limit the use of such labels. From Camila Corval├ín, a nutritionist at the University of Chile who helped develop the labels: “The fact that the industry is freaking out is reassuring, but at the same time it’s worrisome that the U.S. government is trying to defend the position of the food industry.”
