The cost of feeding a family of four in 2013

The USDA regularly monitors what it costs to feed a family of four in the U.S. This morning on "Early Start," we're getting a new look at exactly how much Americans shell out for food every week. Christine Romans shares details.

It costs a family of four about $21 a day for food, and on a weekly basis the thrifty plan is $146. On a more generous plan, families are looking at spending $289 a week for grub.

The USDA crunches these numbers so it has a guideline for nutrition assistance, or food stamps.

There are some common sense ways to make the low-cost food plan work, including:

* Avoid buying pre-cut, pre-washed or instant food.
* Canned or frozen vegetables can be cheaper than fresh.
* Cook meals that stretch, like stew and casserole
* Plan your meals.
