How the Sugar Industry Shifted Blame to Fats

From NY Times Article

The New York Times published on 9/12/2016 an article by Anahad O'Connor  titled:  "How the Sugar Industry Shifted Blame to Fats" which quoted a study in a publication of the Journal of the American Medical Association (JAMA-Internal Medicine).  The study done by Stanton Glantz of University of California San Francisco (UCSF) reported that in the1960s the Sugar Research Association paid three Harvard University scientists to publish a report in the New England Journal of Medicine that explained that dietary fats were more likely to be the cause of heart disease rather than sugars.  That study became a "turning point" in history and promoted significant changes in American's diets and triggered hundreds of studies looking into how fats contributed to heart disease.

Over the 50 year since that time, most of the types of dietary fats have been released from suspicion. However, it now appears that sugar is much more likely a cause of heart disease, obesity, diabetes, and tooth decay, and is a much more worrisome ingredient of our diet.
Who can we believe?  When scientists get backed overtly or covertly by industries with huge investments on the line, how can we protect ourselves from false claims of scientific evidence?  So for 50 years, which is most of my life, doctors, dieticians, and health professionals have been providing incorrect, or inaccurate advice about my diet!  How has that advice affected the total population of the US --and, in fact much of the world!   It is clear that we need to be more suspicious of revolutionary findings done by scientists, and now we do need to change our eating habits to reduce the amount of sugar in our diet.
This report also shows how influential a few, somewhat "rogue" scientists can be on matters of public policy.  Just a few scientists backed by the tobacco industry delayed restrictions on tobacco, very few scientists backed by the coal industry have seriously delayed the world's response to global warming.  How many more situations like that will we uncover?
