Pre-Thinking:

What kinds of foods do you find satisfying? Is there a relationship between your mood and your food preferences? Why do we eat and why do we stop eating when we are full (at least most of the time!). Does our stomach somehow communicate with our brain, or does it have a mind of its’ own. Join research chemist Heribert Watzke as he tackles these and other interesting questions.

Who is he:

He is a research chemist who has been engaged in cross disciplinary studies of food, nutrition and neuroscience since the 1980s. His goal is to understand our human reaction toward the foods we eat and to create better foods.

Why you should listen:

The work of Dr. Watzke will help psychologists to understand the epidemic of obesity that is sweeping our land. Discussion Questions

  1. According to Dr. Watzke, our teeth suggest that humans are designed to eat what sort of a diet?
  2. Explain what he means when he says, “brains are expensive”.
  3. What does digestion discomfort communicate?
  4. Ghrelin is produced by the stomach for what purpose?
  5. According to operant conditioning theory, what is the reinforcement for eating cooked food?
  6. Do an experiment with cooked and non-cooked food. Which is preferred? Is your finding consistent across all foods, or is there variability? If there is variability, how might it be explained?

Making Connections:

Once thought to be mainly a problem associated with adulthood, obesity now affects one in five children under the age of 4. This video describes some of the most recent research on the disturbing trend toward childhood obesity in America.
