What are whole grains?
Grains like wheat, barley, rye and oats, are made up of three parts; the endosperm, the bran and the germ.
The endosperm, a concentrated source of starch, makes up about 80% of the whole grain. Bran, the outermost layer, is a rich source of dietary fibre, B vitamins and phytochemicals. While the germ contains, ‘healthy’ fats, B vitamins and vitamin E.
As the name suggests, wholegrain foods are those which contain all three parts of the grain. |
