can anyone tell me where to find out what foods we can take with us on our camping trip to the USA

And ask about food restrictions for entering the US. (701) 263-4513 or (701) 263-4460.

Not sure if it's up to date. We are also going camping in the US.

you cannot take fresh veggies or fruits.

Getty said "you cannot take fresh veggies or fruits. "

After a quick search on the US Custom & Border Protection Website it states:  
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: You may also call APHIS at 301-851-2046 or toll-free at 877-770-5990.  
 
The US Border website is https://help.cbp.gov/app/answers/detail/a_id/1273/~/food-bring-personal-use-food-into-the-u.s.-from-canada  
 
Whatever you are taking, generally if it commercially packaged and labelled, you are ok. But I agree, call the crossing that you will be going through to check any thing you are not sure about.

just talking about my personal experience. We had gone down about a month ago. Had some apples and a banana, and they border guard made us shoot it in the garbage prior to crossing.  
 
So yeah, just call and ask.  
 
I know the other way around you can bring anything into Canada from US
