Contrary to its name, buckwheat has nothing to do with wheat. It is actually a fruit seed that is related to rhubarb and sorrel. A naturally gluten-free food, buckwheat is a great choice for coeliacs and those avoiding ordinary wheat products. A heavyweight in nutrition, each tiny seed is packed with the beneficial antioxidant flavanoids, including rutin, which may help protect against bad cholesterol and heart disease. Buckwheat contains all the essential amino acids plus vital complex carbohydrates as well as iron, potassium, manganese, magnesium, calcium and plenty of dietary fibre. Roasting buckwheat before cooking creates an earthier, nuttier taste and aroma.
