Calorie counts would appear in larger, bolder type, and consumers would know for the first time whether foods have added sugars.
Under the Obama administration's plan, labels would also feature more realistic descriptions of a serving.
Under the plans, a 20oz (0.5kg) container of soda would count as one serving, rather than 2.5 servings, as it is currently.
The serving size listed on ice cream cartons, currently half a cup, would increase to one cup.
The food label revisions would also include mandatory potassium and vitamin D amounts.
