> A little known fact is that Germany resorted to using sawdust in bread when they had flour shortages during the world wars That wiki article suggests the use of sawdust in bread during WWI, but for a reference uses another encyclopedia-like source [1] (which does not cite any reference, and whose about page suggests it was written by a single individual). While it may be true, I'd be very hesitant to accept it without seeing a better source (and preferably one made before the wiki-circular-citation thing started).
