Here's a few highlights about things you can bring over the border (particularly for Cdn travelers). That said, we personally find it too much hassle and just grocery shop in the US. DH just get too stressed. We do bring stuff like hotdogs and lunch meats. I wish I can get DH to be more comfortable about meat products though. Right now we rarely camp in the US because I hate taking the time to grocery shop on our way and it's a pain not to be able to pre-cook and do prep at home.
I am a Canadian Citizen and want to bring Canadian food products?
General Food
The following are generally admissible if they are unopened and commercially packed. Many prepared foods that are unopened and commercially labeled are admissible (excluding meats and meat products). You may bring bakery items and most cheeses into the United States. As a general rule, condiments, vinegars, oils, packaged spices, honey, maple syrup, coffee, fish, tea, and baby formula are admissible. Because rice can often harbor insects, it is best to avoid bringing it into the United States, particularly if it is in loose burlap packaging. Foods in packaging that appears unsafe or contaminated may be refused entry.
Fruits and Vegetables
Canadian grown fruits and vegetables grown during the typical Canadian growing season, May-October, are
generally admissible if they are labeled identifying them as products of Canada. The best source for the current fruits and vegetable status on crops originating from Canada can be found on page 140 of the Animal and Plan Health Inspection Service (APHIS) website:
http://www.aphis.usda.gov/import_export/plants/manuals/ports/downloads/fv.pdf. You may also call APHIS at 301-851-2016 or toll-free at 877-770-5990. Every fruit or vegetable must be declared to a CBP Agriculture Specialist or CBP Officer and must be presented for inspection - regardless of its admissibility status. Fresh fruits and vegetables need to be clean and may be prohibited if they have insects or diseases.
Animal Products and Animal By-Products
The importation of fresh, dried or canned meats or meat products is generally not allowed from most foreign countries into the United States. This includes products that have been prepared with meat. However, currently
pork and poultry, which has proof of origin, from Canada is enterable. Not all Ruminant material can enter however
personal use amounts of bovine meat or foods containing bovine meat or meat products (e.g., beef, veal, bison) are allowed in passenger baggage and mail, no import permit or other documentation is required.

The regulations on importing meat and meat products change frequently because they are based on disease outbreaks in different areas of the world. The best source for the current disease status can be found starting on page 19 of the APHIS website:
