The Nazi Seduction cites some fascinating passages from The Nazi War on Cancer:
Nazi nutritionists stressed the importance of a diet free of petrochemical dyes and preservatives; Nazi health activists stressed the virtues of whole-grain bread and foods high in vitamins and fiber. Many Nazis were environmentalists; many were vegetarians. [Including Hitler himself.] Species protection was a going concern, as was animal welfare. [Reichsmarschall Hermann Göring barred vivisection in all scientific work noting the "unbearable torture and suffering in animal experiments" and he threatened to commit to concentration camps "those who still think they can treat animals as inanimate property."] Nazi doctors worried about overmedication and the overzealous use of X-rays; Nazi doctors cautioned against an unhealthy workplace and the failure of physicians to be honest with their patients — allowing momentous exclusions, of course, for the ‘racially unfit’ or undeserving.
Nazi Germany sounds a bit like California:
The Nazis had established the link of smoking to lung cancer decades before public health officials in Western democracies acknowledged this fact. In fact, Nazi Germany first established the tobacco-lung cancer link in the late 1930s. Smoking was banned in public places. Even soldiers were barred from smoking openly on the streets. “Sixty of Germany’s largest cities banned smoking on streetcars in 1941 and smoking was banned in air-raid shelters. ? Smoking was banned on all German city trains and buses in the spring of 1944; Hitler personally ordered the measure to protect the health of the young women serving as ticket takers.” An educational campaign blanketed the Third Reich with information and propaganda urging pregnant women not to smoke for fear of harming the unborn child. The Nazi state attempted to “curb asbestos exposure” and to “secure food quality.”

There is more. Nazi “nutritionists mounted a frontal attack on the Germans’ excessive consumption of meat, sweets, and fat, and argued for a return to ‘more natural’ foods such as cereals, fresh fruit, and vegetables.” Repudiating the public/private distinction central to liberal societies and liberal political philosophy, the Nazis declared that the personal was indeed the political. One slogan declared: “Nutrition is not a private matter!” Each person’s diet was a matter of state concern, for the state was responsible for the health of the body politic. Hitler himself declared that “reforming the human lifestyle” was “far more important” than anything else he might accomplish. Hitler loathed obesity and launched campaigns against it both within the ss and in the polity at large. Mothers-to-be were urged to “avoid alcohol and nicotine during pregnancy and while nursing”; one poster that blanketed the Reich urged prospective mothers to “Drink soft cider instead!”
