As you can see the germ and bran contain lots of healthy stuff that is not found in the endosperm. Whole grains are cereal grains in their natural state ie they contain all three main parts endosperm bran and germ. Refined grains are groats from which the bran and germ have been removed by grinding and sifting. Refining causes the grains to lose some of their nutritional value. Sometimes nutrients such as vitamins are added back. But as these represent a small fraction of the nutrients removed refined grains are nutritionally inferior to whole grains. Removing the bran and grinding the grains into a fine powder increases the glycemic index value (GI) of the grain ie you digest glucose from refined grains quicker than glucose from whole grains which as a diabetic is not what you want.
The intuitive answer is that it must worsen the GI value because it introduces air into the matrix. But according to researchers in New Zealand the leavening agents used in making bread do not have any impact on the GI of the bread. Types of bread There are hundreds of different breads in the world. Here are a few of the most common. Notice the subtle differences which may or may not be designed to confuse the consumer. White bread is made from refined flour ie grain from which the bran and germ have been removed so that it only contains the endosperm (the central core of the grain). By contrast wholemeal bread is made from the whole of the wheat grain (endosperm bran and germ) ie from unrefined flour. Brown bread is not the same as wholemeal bread.
This produces bubbles of carbon dioxide which makes the dough rise. This kind of leavening requires proofing ie a resting time to allow the yeast time to reproduce and consume carbohydrates. Breads leavened with yeast have a distinctive flavour. A sourdough starter is a paste of flour and water containing yeast and lactobacilli which has been obtained from a previous batch of dough. It works in the same way as yeast by creating bubbles but it requires much more proofing time than yeast. Sourdough bread has a sour tangy taste. It is used for rye-based breads where yeast is not really effective in leavening the dough. Chemical leaveners are chemical mixtures that release carbon dioxide or other gases when they react to moisture and heat.
