Registered Dietitian, Neva Cochran, responds to Dr. Robert Lustig's theory that all sugars, and particularly fructose, are driving obesity rates in the U.S. and that a "calorie is NOT a calorie." Neva called in to ask a question of Dr. Lustig when he was a guest on the Diane Rehm NPR show, January 7, 2013. To listen to Neva's question and Dr. Lustig's reply, go to http://thedianerehmshow.org/audio-pla... and advance the audio to 47:00 minutes. As it states in the video, Neva is consultant to the Corn Refiners Association. Her opinions and statements, however, are her own and based on peer-reviewed scientific studies. She said the same things before working with CRA and will do so after, as well.
