KEARNS: The 1960s was really critical for the diet and heart disease debate. There really were two sides of the story. One, evidence was linking sugar to heart disease, while on the other evidence was linking saturated fat to heart disease. Some people were saying that both were a problem. The sugar industry took that opportunity very early on to enlist these Harvard scientists and write a very influential review that was published in The New England Journal of Medicine that critiqued the evidence linking sucrose to coronary heart disease that served to shift us off of that path.
