one quick simple question

I know there's probably a thread, or something in reference to what i'm about to ask.
What can I NOT bring back with me from the states food/drink wise? And how much am I limited to, if any limit?
I'm going home the 26th and have a list, is there a limit to what I bring home, or what I bring?
Any ideas or whatnot would be really appreciated.

I dunno about the amounts, but I do know that you can't bring any meat, veggies, or fruits.  No homemade items.  Only processed, packaged foods--you know, the good stuff!   

Thank you so much for the info lolabola, glad someone replied LOL sad to say but I fear i'll still be clueless, tho thanks to ur input, not so much now (didn't think I could bring back drinks, but figured at least dried things in cans etc) just hope there's not a limit.
