The most popular is baking powder a mixture of a carbonate or bicarbonate (usually sodium bicarbonate) and one or more acid salts. Baking powder works by releasing carbon dioxide gas into the dough when it gets wet creating bubbles that expand the wet mixture. It is used instead of yeast for breads where the flavours of fermentation would be undesirable or where the dough lacks the elastic structure needed to hold gas bubbles for more than a few minutes. Because carbon dioxide is released at a faster rate through the acid-base reaction than through fermentation breads made by chemical leavening are called quick breads. Examples of quick breads include Irish soda bread banana bread pancakes carrot cake and muffins.The big question for diabetics of course is whether the rising method has any effect on the glycemic index (GI) value of the bread.
To beat your diabetes you need to eat food that is low in sugar low in fat low in salt high in fibre and has low GI values ie it releases glucose into your bloodstream relatively slowly. Some kinds of bread fit this bill; others do not. Bread is made from flour ie grain that has been ground into powder. Common wheat is usually used because its flour has high levels of gluten which gives the dough sponginess and elasticity. But bread is also made from other species of wheat (eg durum and spelt) and other grains such as rye barley corn (maize) and oats. The non-wheat grains usually have wheat flour mixed into the flour. The quality of bread depends largely on the protein content of the flour. The best breads use flour with 12 to 14% protein rather than all-purpose wheat flour which only contains 9 to 12% protein.
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.
