More Americans than ever have been reading those FDA-mandated food labels before buying packaged foods. Yet they haven't been changed in decades. Now... there will be a change mandated for food labels in your grocery store as part of an effort to reduce obesity across the United States.

FOX's Alex Hein reports:

This is Housecall for Health.

Nutrition facts labels on food packages will be getting a long-awaited makeover with calories listed in bigger, bolder type and a new line for added sugars. Serving sizes will also be updated to make them more realistic so a small bag of chips doesn't count as two or three servings.

The changes were first proposed two years ago by the Food and Drug Administration and are the first major update of the labels since they were created in 1994. While fat was the focus when the labels were created, there's now more concern about how many calories people eat.

The calorie listing will now be larger than the rest of the type making it had to overlook. Serving sizes will be easier to see and it will be easier to figure out how many servings are in a container.

The food industry has two years to comply, and while some companies have fought the new line for added sugar, others have supported it.
