Yes.  I have brought home Vietnamese coffee on a few occasions.

What you CANNOT bring (food wise):

 - any FRESH fruit, vegetables, plants, spices: fresh produce of any kind
 - meats and fish, even when cooked and processed, are not allowed.  I was denied bringing smoked reindeer from Finland.

I routinely bring in:

 - processed / dried herbs and spices
 - dry tea
 - roasted coffee
 - a kind of yogurt sold in the nordics

Most processed and packaged food CAN be brought in, but maybe not meat/seafood.  Most fresh foods cannot.  I am unsure of green coffee.

Wet foods from Thailand (fresh curry paste and coconut sugar in particular) were allowed, BUT they showed up on the bag scanner and caused my bag to be searched.  I'm guessing that in an xray they have a similar appearance to certain explosives.

A FEW spices are occasionally banned in any form: Sichuan peppercorns (which can carry a virus harmful to citrus crops, to which they are related); cumin in any form was not allowed once, which also means many kinds of curry powder.
