Wholegrain cereals contain the three layers of the grain. Wholegrain cereals contain more fibre, vitamins, minerals and antioxidants than refined cereal foods such as white bread, because many of the important nutrients occur in the outer layer of the grain which is lost during processing. Wholegrain foods are particularly important in vegetarian diets as a source of iron and zinc. Wholemeal foods are made from wholegrains which have been crushed to a finer texture. Nutritionally, wholegrain and wholemeal foods are very similar. Choosing wholegrain varieties is best.
