Sustagrain® Barley Flour: Super Fiber, Superfood, Only Available at Ardent Mills

Take advantage of all the benefits of barley with Ardent Mills Sustagrain® Barley Flour. This proprietary variety of barley contains the highest fiber content of any commercially available whole grain. With over 3 times the dietary fiber of oats and at least 10 times the fiber of brown rice, this proprietary variety of barley is among the lowest glycemic index grains commercially available.

Available in formats ranging from flakes to flour to custom multigrain blends, Sustagrain® Barley Flour can be used in baked goods, energy bars, cereal, pastas, and extruded snacks, where its high water absorption can help increase moistness and slow staling.
