Chapter 4

Introductory discussion: (beginning of chapter)

  • The Whet your Appetite section of this chapter prompts students to identify the asserted benefits of raw food diets.
    • Ask students to contrast the experience of eating certain types of food when raw versus cooked, e.g. animal protein (meat or fish), eggs, grains (corn or rice), root vegetables, fruit
    • Inquire whether there are differences across global cuisines in the consumption of certain food items as cooked or raw.
    • Encourage students to identify strengths and limitations (even dangers) of the raw food trend.
  • Next, the Amuse Bouche asks about the popularity of the Paleo diet trend.
    • Students should first identify the guidelines of the modern paleo diet, including the types of foods that are encouraged and prohibited from consumption.
    • Again, prompt students to identify the known benefits and limitations of this diet trend.
  • Encourage students to about this appeal of a (mythical) ancestral past. Where else do we see calls to return to an earlier time, and what is the attraction of the past?
