Yes. Oatmeal is a whole grain cereal. Approximately 12% of each whole grain oat is the bran portion. Therefore, every time you eat Old Fashioned or Quick Quaker Oats, you're eating oat bran. Old Fashioned and Quick Quaker Oats contain one ingredient: whole rolled oats. Since oat bran is a natural portion of the rolled oat, it is not technically considered a separate ingredient. To identify products containing oat bran, look not only for oat bran, but also for rolled oats and whole oat flour on the ingredient label.
