I'm new to the program and trying to figure things out. Weetabix cereal is my favorite. It's not too popular is the U.S. so I can't figure out if its core from my meetings.
The food guide lists Barbara's Bakery Shredded Wheat as Core, but it doesn't have any sugar (cane juice) or anything else added. Maybe you could buy some type of shredded wheat and add a little Splenda or something.
