One of my favorite foodie sites out there is Chow. They've got great restaurant reviews, an incredibly robust forum full of gourmets who know just what they're talking about and will tell you when Costco's got Coca-Cola from Mexico (made with real sugar! unfairly delicious), a lot of great blogs, and my favorite, the Supertaster column. The Supertaster takes on all the packaged, processed foods in the world that are tempting in their convenience and availability and reviews them, so that you don't have actually find yourself longing to put these things in your mouth--but then there are the reviews of lovely things like gourmet crackers and tasty oatmeals to guide your steps in the supermarket. He's funny, he's honest, and he's got your back when you're thinking maybe a protein bar is a good idea for breakfast.
