I just started SBD, and have two food questions that I couldn't find:

Polenta: Is it "allowed"? And in what phase?
Cranberries: Are dried cranberries a no-no in all phases?

Welcome to 3FC and to the Beach.

Polenta is not allowed in Phases I and II of South Beach as it is made from corn. Corn is a very high GI starch and can be eaten only sparingly in Phase III. The Guide says "very limited".

Dried cranberries contain sugar and are a no-no in the first two phases but can be used sparingly in Phase III. Too bad they can't dry cranberries with Splenda instead of sugar!
