I don't know why this was re-posted today (kind of suspicious that this floats again after 10 year just by chance) anyway, there is a full citation-heavy book by Gary Taubes about this, and one of his points was that the sugar industry paid 2 million in 1970's dollars to create the nutrition department of Harvard, which was the first nutrition department in the world. (This was to say that nutrition science itself has been corrupt since its birth).
