Whole wheat with its vitamin B content helps provide the body with energy. Moreover, the whole grain contains complex carbohydrates, which keeps you feeling full longer and gives you energy over a longer period of time. The normal bleached white flour is obtained by processing after 60% extraction from the grain. Usually, the 40% that is removed – the outer brown layer – contains the highly nutritious bran and the germ of the wheat grain. In the process of making 60% abstraction flour, more than half of the vitamins B1, B2, B3, and E, calcium, phosphorus, folic acid, copper, zinc, iron, and fiber are lost.
