“Viewpoint” host Eliot Spitzer is joined by Marion Nestle, a professor of Nutrition, Food Studies and Public Health at New York University, and Marc Murphy, executive chef at Benchmarc Restaurants and a City Harvest board member, to talk about obesity in the United States. Spitzer asks both guests whether losing weight is first and foremost a matter of personal responsibility, or whether the government should get involved by imposing taxes on soda, for example. “Personal responsibility hasn’t changed since 1980, but rates of obesity have,” Nestle answers. For Murphy, education is the key: “Why don’t we make school lunch part of the curriculum? … I’m a huge advocate of teaching and I think that education is the way to go, not legislating, not taxing people.”
