Here's an interesting video from Stefani Bardin, a TEDxManhattan 2011 fellow, and Braden Kuo, MD, a gastroenterology instructor at Harvard. According to their description, the video uses "the M2A and SmartPill devices to look at how the human body responds to processed versus whole foods." While I'm by no means an expert on this subject, the video makes for some interesting watching.
