Whole grains are recommended as part of a healthy diet, to help reduce the risk of heart disease and Type Two diabetes. They are an excellent source of dietary fibre, too, a key ingredient in keeping the digestive system running smoothly and maintaining a healthy weight.

Barley, brown rice, buckwheat, cracked wheat (bulgur) and oats are common whole grains. But there are several other grains that have largely been ignored until recently.
