7. Food

In this episode, you'll discover that what goes into your stomach has less to do with your mouth and more to do with your brain. You'll see what happens when we turn up the volume on our test subjects' appetites through sound and smell, and learn how many of your food choices often have nothing to do with food. Through a series of interactive games and experiments you'll discover what makes you hungry, why you overeat, and whether you should take comfort in comfort food.
