                                Derived from the indigestible hull of the oat grain, oat fiber is a versatile, zero-calorie ingredient that has become a staple in low-carb and keto baking. It is prized for its ability to add bulk and texture without adding carbs or calories, making it a powerful tool for fiber fortification and moisture retention.
