Lecture 7: Food and Eating
* Today’s lecture good for essay
- The essay in many ways captures the deepest learning out of most of the course
- The essay allows you to dive into your own research and find peer reviewed work to
create a deep insightful argument
- Lecture gives you key ideas you can talk about
- You cannot reference lecture notes (have to find original reference)
- Need to read widely and deeply for argument (3 references not enough, 50 too much)
- Need to be place that you have read more than you can incorporate in your essay
Role of Food in Society
- When we think about food we are tempted to think about this in a biological way
- Food has a richer role in human society
- Food is a social activity (family meeting around table, celebrations, festivals)
- Different foods have different cultural meanings
- Over time changes in society have led to changes in consumption habits
- As health psychologists, look at connection between food trends and health outcomes
Look at extremes of eating behaviour (anorexia and bulimia, obesity)
- A lot of food debates are captured by something we say in the media a few years ago
Michelle Obama key player
Conflict with Sarah Palin, there was tension between the two
Michelle Obama was proposing a national healthy food program in schools (seems
like a good idea, but why would someone have a problem with that?)
Argument again healthy food program may be in terms of free will, less healthy foods
are cheaper
Michelle Obama (we should have a national program,)
Sarah Palin (we should not)
Sarah Palin was saying who is Michelle Obama to tell me what I should feed my kids
(telling the government it is not their business)
- Remember: Where is the role of the government? Where is the role of individual in
making healthy food choices?
Crux of the matter
