+If there is the one food from Germany it is probably bread. There are thousands
+of different varieties of bread in Germany. Making bread has been an integral part
+of our culture. Beginning my studies in Göttingen for the first time I was faced
+with buying bread on my own. In Germany that is no easy task
+as the varieties of bread are endless. I started to check the packaging
+of different bread types and noticed how there were surprisingly
+many ingredients in most of the breads found in a common supermarket.
