Is it true that Mexico's NOM-051 standard requires front-of-package warning labels on foods with excess sugar, calories, sodium, or saturated fat, and the labeling requirement took effect in October 2020?

Yes. One source states directly that Mexico's NOM-51 front-of-package warning label regulation went into effect in October 2020 and sets thresholds for energy, saturated fat, trans-fat, added sugars and sodium; other sources confirm Mexico's warning label system took effect in October 2020 and covers excess calories, sugars, fats and sodium.
