>Today's health crises, which exploded around 1980, can be traced back to the media trumpeting the twin (false) claims that dietary fat is evil and that corn syrup is a healthful alternative to sugar.

I'm surprised you think this is only the media's fault:

"In January 1977, after listening to the testimony of Ancel Keys and other doctors and scientists intent on promoting the unsupported Dietary Fat-Heart hypothesis, the Committee published the "Dietary Goals for the United States" recommending that all Americans reduce their fat, saturated fat and cholesterol consumption, and increase their carbohydrate consumption to 55-60% of daily calories."
