Instruction: I'm confused as to which of these food staples have gluten and which are gluten-free. From this list can you tell me which is which: Pasta, rice, potatoes, noodles and bread.

Response: Rice and potatoes do not contain gluten, so they are gluten-free. However, pasta, noodles and bread usually contain gluten. 

There are less common varieties of these staples that do not contain gluten, but you will need to check the packaging details to ensure that they are gluten free.
