White bread typically refers to breads made from wheat flour from which the bran and the germ layers have been removed from the whole wheatberry as part of the flour grinding or milling process, producing a light-colored flour.
Rye bread is a type of bread made with various proportions of flour from rye grain. It can be light or dark in color, depending on the type of flour used and the addition of coloring agents, and is typically denser than bread made from wheat flour. It is higher in fiber than white bread and is darker in color and stronger in flavor.
Sourdough bread is made by the fermentation of dough using naturally occurring lactobacilli and yeast. It uses biological leavening rather than using cultivated baker's yeast. The lactic acid produced by the lactobacilli gives it a more sour taste and improved keeping qualities.
Pita or pitta, is a family of yeast-leavened round flatbreads baked from wheat flour, common in the Mediterranean, Middle East, and neighboring areas.
