Consumer advocates, nutritional geeks and Atkins freaks really love to speculate about how the "evil industry" influences with lobbying and dubious financial subsidies in politics, science and society in order to maximize their profits at the expense of consumers and their health.
Unfortunately, such machinations are often very difficult to prove or understand: By its nature, these kind of manipulations are kept very secret and happen in the background.
Recent Study from Archival Documents
A significant amount of fuel, was dumped on the fire of such conspiracy theorists on September 13 2016, since a study was published on that day, which suggest just that: Conspiracy and Manipulation by the Sugar Industry. The authors of that study have compiled a number of documents from the 60s and 70s, which show in detail how the Sugar Industry in the United States systematically downplayed the risks of sugar for cardiovascular disorders and at the same time upgraded the role of cholesterol and saturated fat in cardiac research in order to promote their interests and profit making.
The paper published in the Journal of the American Medical Association (JAMA) called, "Sugar Industry and Coronary Heart Disease Research, A Historical Analysis of Internal Industry Documents" (download below) reads like a Agatha Christie thriller: like detectives, the authors scrambled through the archives of the Sugar Research Foundation (SRF) and accumulated hundreds of documents and correspondence to re-construct in acribic detail how the SFR influenced scientific research in the sixties and seventies in a systematic fashion to promote their own interests.
Things kind of started in the fifties with the fact that the incidence of cardiovascular diseases was rapidly increasing and therefore science research was highly interested to deal with the issue and find the cause thereof.
