I was looking up scran bran earlier and found the two types in a health food shop near me. Apparently when I looked to see what the difference is oat bran (if that is the main ingredient) is sort of the opposite of wheat bran. Wheat bran isn't digestible, but oat bran is. I can't remember if it is higher in calories or higher in fiber, but if you google difference between them it will tell you. Oat bran is good for lowering cholesterol tbough
