Is sugar about to have its tobacco moment? The answer is … complicated. In the ’60s, the industry paid scientists to play down the link between sugar and heart disease.

Guest host Stephen Henderson of the Detroit Free Press is joined by Gary Taubes, author of “The Case Against Sugar,” Michael Moss, author of “Salt Sugar Fat: How the Food Giants Hooked Us,” and Courtney Gaine, president and CEO of The Sugar Association. Joshua Johnson returns tomorrow.
