garrett,

It depends on the country you're coming from and the type of food you wish to bring. Here is the official word on what food can and cannot be brought into the United States:

Travel light - don't bring anything but the clothes you want - I bring less and less every year and am happier each trip. The first year we brought way too many clothes. The second year we brought two of the kids and brought food for them. That is the last time I brought any food. You can get whatever you want at the local store and there is no shortage of beer.
