Here is the link Emergency Preparedness (year's supply of food, 72 hour kit). The list tells you how much to get for each person, so it is useful for single people also. I highly recommend storing what you will eat, nothing worse than having to eat something you don't like. I'm single also, so if you have any questions about what to store, let me know.
Better safe than sorry, but Germany has plenty of good food!
I was stationed in Bulgaria for two years with my family a while back and I was warned to ship at least 2,000 pounds of "consummables". We did, and I didn't need any of it. All we had to do was adapt. Bulgarians at that time were much leaner than Americans, but still strong and healthy. We became frequent visitors to the local farmers market.
