As far as dieting goes, and probably health too, they are about the same. The fat,carbs, and protein ratio is almost identical as rolls said. Its almost like eating white bread then taking a fiber supplement, or mixing 5 grams of shredded fiber in dextrose. Most foods with fiber in them are considered good because they tend to be low in calories too. Wheat bread is a processed food too, I'm pretty sure. I think Good carbs are the ones that are non-processed and have fiber in them naturally occuring. If you got to chose one, then I guess wheat is slighty better if it has extra fiber. Both are too high in calories to be considered great dieting foods though.
