Author Robert Payne, in his biography of Hitler, The Life and Death of Adolph Hitler (Praeger, 1973) theorizes that the image of Hitler as a vegetarian ascetic was deliberately fostered by propaganda minster Joseph Goebbels:
"Hitler's asceticism played an important part in the image he projected over Germany. According to the widely believed legend he neither smoked nor drank, nor did he eat meat or have anything to do with women. Only the first was true. He drank beer and diluted wine frequently, had a special fondness for Bavarian sausages and kept a mistress....His asceticism was a fiction invented by Goebbels to emphasize his total dedication, his self-control, the distance that separated him from other men....In fact, he was remarkably self-indulgent and possessed none of the instincts of the ascetic. His cook, an enormously fat man named Willy Kannenberg, produced exquisite meals and acted as court jester. Although Hitler had no fondness for meat except in the form of sausages and never ate fish, he enjoyed caviar...." (p. 346)
Pigeon was his favorite apparently. He did avoid many rich foods (they upset his digestion, a bad thing since he had chronic flatulance). After his niece died the sight of blood bothered him, which limited the flesh-foods he could consume. It is difficult to separate propaganda from reality with Hitler's diet but it is significant that vegetarianism is mentioned in Mein Kampf ... never. Not once. If it was central to Hitler's world view ya think he woulda at least mentioned it in the book that outlines that view.Hitler wasn't even a vegetarian, anyway.Didn't he eat sausage and turtle soup and fish and stuff?
Nothing, (well, arguable
