In the video above, and in a graphic called "The Nacho Dorito," Michael Moss explains how food scientists have made this snack so compelling. Watch the video first, then read the graphic, using both to answer these questions. WHEN did you last have a Dorito? A Dorito Loco Taco? WHO is Michael Moss, the narrator of the video above and the creator of this related graphic? WHAT is psychobiology? WHAT is "dynamic contrast"? WHAT is "mouth feel"? HOW do the acids in Doritos work on the brain? WHAT is "sensory-specific satiety"? WHAT else is in Nacho Cheese Doritos? WHERE do half the calories in Doritos come from, and, according to the graphic, HOW does that work on the brain? WHY is "forgettable flavor" so important to Doritos" success? Now that you've watched the video and read the graphic, explain WHY you think Mr. Moss describes the new Doritos as "a marriage made in processed-food heaven." Now that you know the formula behind Doritos, are you more likely to eat more or less of them? HOW many processed foods do you eat a day? HOW do you imagine a unprocessed food might compare with Doritos in terms of how it works on your brain and body? WHAT might a graphic explaining the effects of this food look like?
