2. From 2002 through 2009, Frieden served as New York City Health Commissioner. He led efforts to reduce smoking, and eliminate artificial trans fats from restaurant food, among other critical initiatives. While serving as commissioner, life expectancy in New York City increased by three years.

“I hope five years from now we’ll look back and see this was the inflection point for rapid progress in preventing global cardiovascular disease deaths and improving epidemic preparedness,” Frieden told The Washington Post. “In a few years, we hope that blood pressure control, sodium reduction, elimination of trans fats and strong public health systems will have become the new normal.”
