When grains are refined all that is left is the endosperm. The endosperm only contains carbohydrates, starch, protein and very small amounts of vitamins and nutrients. After the refining process a grain has lost about 25% of its original proteins and many nutrients. Below is a link to a great chart about the loss of nutrients by the Whole Grains Council: http://wholegrainscouncil.org/files/backup_migrate/WGvsEnriched2011.pdf
Once most of the nutrients are taken out of wheat there is not much left worth eating. As well as losing many nutrients a lot of fiber is lost in the refinement process. Below are three examples of ways that wheat is being treated. Two of them are refined wheat.
1) Whole Grains (the grain is never refined). You want to make sure never you never confuse whole wheat bread with wheat bread. Any bread made out of refined or whole wheat flour is wheat bread because it contains wheat. Even some whole wheat breads contain unnecessary additives and preservatives. You want to read the ingredients of bread before you buy it. Ideally you would make it (I will blog about this later) but everyone does not always have time for that.
