This is a great question, Nico. I would love to find something along these lines, too.
A pretty fascinating part of it would have to be the whole Battle Creek Sanitarium nexus in the mid-1800's to early 1900s. There you have existent Protestant obsessions with purity and revulsion towards animality (see Kellogg and Graham equating flesh consumption with sexual lust over and over again, with scary leaps and consequences, advocating fasts and veganism as a way to curb dangerous base desires) coming together with the social movements of the time (temperance, abolitionism, and yes, eugenics), big business (Kellogg and Post eventually give birth these now huge companies by investing grains with timely moral significance) and people of great influence (patients included presidents, celebrities, authors, industrialists, abolitionist leaders, and more.) While one can chuckle at the most egregious examples of wackjobbery found in this movement, you can't ignore the long-lasting effects that it has wrought upon America, its people, and notions about health. (This post has inspired me to delve deeper into this. Plan on picking up this and this book soon...)
Upton Sinclair was also a patient and I don't think one can forget the role his works, as important as they were to bringing attention to the dangers of industrial food production, had in helping spread the red meat=unhealthy/bad/gross equation. Interestingly, I recently came across a quote from him that surprised me in a good way:
Recently a friend called my attention to the late Dr. Salisbury's book, "The Relation of Alimentation to Disease." Dr. Salisbury recommends a diet of broiled beef and hot water as the solution of most of the problems of the human body; and it may be believed that I, who had been a rigid and enthusiastic vegetarian for three or four years, found this a startling idea. However, I make a specialty of keeping an open mind, and I set out to try the Salisbury system. I am sorry to have to say that it seems to be a good one; sorry, because the vegetarian way of life is so obviously the cleaner and more humane and more convenient. But it seems to me that I am able to do more work and harder work with my mind while eating beefsteaks than under any other regime; and while this continues to be the case there will be one less vegetarian in the world.
