Garlic??? 
 So what's up with the lack of references.  The Garlic and Halitosis comment is so specific, but I can find nothing to support it.  The fact that my German father hated garlic breath with a passion, made me think there might be something to it, but if Germans have had a unique distaste for garlic, I'd like to see some sources for it.  So much of this lacks support, well beyond the Garlic item, it should almost be scrapped and redone.
