During World War I I what sort of rations were provided to soldiers the Wermacht? American soldiers commonly ate spam as their staple meat, did the Germans have any product that they ate to the point of hating it?

Chapter VI of War Department Technical Manual [TM-E 30-451] (http://usacac.army.mil/cac2/cgsc/carl/wwIItms/TME30_451_1945.pdf), Handbook on German Military Forces, is concerned with Supply, Evacuation, and Movements. In general terms Section IV, Maintenance Requirements, details four types of daily ration quantities: for troops committed to combat, recuperating from combat or in northern Norway (Ration I); occupation and line-of-communication troops (Ration II); garrison troops in Germany (Ration III); and office workers and nurses in Germany (Ration IV). Total maximum ration quantities range from 1698g (Ration I) to 1483g (Ration IV) and consist of bread, meat/fish/cheese/eggs, vegetables, puddings and milk, seasoning, butter/lard/fats, coffee and sugar.

In the field troops could be issued with an iron ration (Eiserne Portion), along similar lines to US Army C- or K-rations, including canned meat and crackers. There's [an article by Doug Nash] (http://www.dererstezug.com/IronRation.htm) about the iron rations including quotes from a post-war U.S. Army Quartermaster Food and Container Institute report concerning the canned meat; apparently the pork was "excellent in both appearance and flavor", and the beef was also "of excellent appearance and palatability".

In the North African campaign German troops received Italian supplies including meat in cans stamped with "AM" for Amministrazione Militare (military administration); this wasn't very popular and gained a number of nicknames amongst Axis troops including Alter Mann (old man), Arab Morto (dead Arab) and Asinus Mussolini (Mussolini's ass). Luftwaffe pilot "Macky" Steinhoff mentions a meal of "old man" and scrambled eggs late in the war, plentiful supplies of AM tins having been taken as booty from Italy.
