Barbara's Bakery High Fiber Cereal has an impressive 14g of fiber with a surprisingly good taste. In fact, this line of high-fiber cereals are all superb choices. Unlike other super-high fiber cereals that contain mostly wheat bran, this one is loaded with whole grains, too, making it a well-rounded choice. Remember, whole grains contain the bran, germ, and endosperm part of the grain (the whole grain) making it preferable to just wheat bran.Cereal stats: Whole Grain: 24g, Sugar: 8g, Fiber 14g
Runner up: Some people just have to have their bran, and our favorite is Kellogg's All Bran with 10g fiber and 6g sugar per serving.
