Wholegrain buckwheatGreat source of proteinNaturally gluten free and low in fat Buckwheat is the seed of a plant called "fagopyrum esculentum." It's related to rhubarb, not wheat, rye or barley and despite the confusing name, buckwheat is gluten-free. Sowan's natural buckwheat is very versatile. Try heating it on a hot pan then sprinkle on a salad, soak overnight in apple juice to make the base for a wheat free porridge or add to your scratch baked Sowan's bread mix for some added protein.
