Wheat bran is the outer hull of the wheat kernel, which is typically removed during processing. Wheat bran is rich in fibre and other noncaloric nutrients.
Mix a small portion of your very high fibre cereal with your regular cereal. Sprinkle bran in trail mixes or yoghurt parfaits. Add wheat bran to hot or cold cereals, smoothies, casseroles. Replace some of the flour with wheat bran when baking muffins, waffles, dinner rolls, etc.
