Professor Brownell gives an overview of the class's agenda. The psychological issues of food
are introduced, such as who defines food, what promotes health, and how the food industrycontributes to both debates. The biological issues that will be discussed include how people's
hard-wired preferences interact with a modern food environment. The political issues of theclass will integrate food production, consumption, marketing, and world politics, with
discussion of potential interventions for changing food preferences and food intake patterns insociety.
The Psychology, Biology, and Politics of Food: Lecture 1 Transcript

Chapter 1. Course Overview and Key Topics [00:00:00]
Professor Kelly Brownell: How are you guys? It's really nice to see you all and I appreciate
you getting up so early in the morning. I realize that Yale students aren't accustomed to
doing that. I served as Master of Silliman College for six years and during that time Iwould get up at 5, 5.30 in the morning and start working. Students would see my light on
in my office and say, "Oh that's great Master Brownell, you stayed up all night just like we
did working," but of course we were on different schedules. So it would have been nice to
have this at a later hour but this was the only time that really worked into the schedule, so
I appreciate you being here. This is a very fun class. We talk about issues that are relevant
to the world, to politics, to economics, and to all our lives. And we're going to talk about
food and the psychology of it, the biology, and the politics, and this morning I'd like to run
through what I mean by those things and what the course is going to be all about. So let
me start off with is this the first day of shopping or was it yesterday?
Student: Today.
Professor Kelly Brownell: So this is the first class, the first moment of shopping that you
guys are going to! Well it'll be interesting to see if you swing at the first pitch and decide to
take this class on. We're going to talk about various aspects of food and I'd like to start off
with a little pop quiz. This is a food, a common food that most people would recognize, and
I'd just like to see if you could guess what it is from the list of ingredients, so take a
moment to look at the list of ingredients and then I'll see if you can guess. Anybody who
7/31/2019 Yale Open Course
2/21
has ideas just shout them out.
Student: Brownie.
Professor Kelly Brownell: Brownie.
Student: Pop tart.
Professor Kelly Brownell: Pop tart.
Student: [Inaudible]
Professor Kelly Brownell: S'mores, what?
Student: A Ho-Ho.
Professor Kelly Brownell: S'mores, okay that sounds
all possibilities. Any other ideas?
Student: M&M's.
Professor Kelly Brownell: M&M's. Okay, well the interesting thing is, you guys in a very
short period of time generated a number of ideas about what this could be. Well the fact is
it could be hundreds of foods in the American food supply, and what's noteworthy about
this particular list of ingredients, is that it's fifty-six entries long; fifty-six things in this
particular food and we defined it as food. Now, whoever guessed it was a pop tart was
correct, that's what it happened to be so you get extra credit for that. And so it's a very
interesting question to ask, what is this? I mean is this is it a food? Should we define
this as a food? Is it a chemical? Because there are a lot more chemical-sounding things inthat list of ingredients then there are things that nature would recognize or we would
ordinarily recognize as food.
One even might go so far as to say that it could be a controlled substance. If food has
addictive properties, and we'll discuss this in the class, then is this the sort of thing that
should get regulated by government? Now that's pretty far fetched and not many people
would say that a pop tart should be a controlled substance and regulated by government,
but there are some very interesting chemical properties associated with foods like this that
trigger things going on in the brain that affect us in a very big way.
Now I'm going to give you another little pop quiz here. I'm going to show you slogans fromfood companies and you guys tell me what foods they're affiliated with, what foods they're
associated with. Okay, 'melts in your mouth not in your hands?'
Student: M&M's.
Professor Kelly Brownell: Okay, you guys are a little slow this morning. It's kind of early
but let's see if you can pick it up. Okay you're right; M&M's. What about, 'obey your
7/31/2019 Yale Open Course
3/21
thirst?'
Student: Sprite.
Professor Kelly Brownell: Okay. 'I'm lovin' it?'
Student: McDonald's.
Professor Kelly Brownell: Okay. I've got a pretty smart group of people here.
Student: Kit-Kat.
Professor Kelly Brownell: Okay. Kit-Kat bar, you're right and one more.
Student: Cocoa Puffs.
Professor Kelly Brownell: Okay. If you guys have had
many health professionals saythat there's not enough nutrition education out there, that most people don't learn it in the
schools, people aren't getting it so much from families because families don't know a lot
about nutrition, but the fact is you've had a lot of nutrition education and you've just
proven it. But the question is "who is it coming from?" Who has taught you and other
people in our culture what food is all about? Who has taught you what constitutes food?
What's acceptable to eat? What's good for us? And there are a lot of interesting things
that the food industry has trained us to believe that experts say may or may not be true.
Because a product has the word 'fruit' in its name doesn't necessarily mean it actually has
fruit in it. Now is that deceptive, is it misleading? Well these are very interesting questions.
This course, as I said, will emphasize psychology, biology, and politics of food. Let's talkabout each one for just a moment. First of all, what you choose to eat, and what the world
chooses to eat, which has enormous impact on the public's health, on the vitality of
countries, and even on world politics. With the recent spike in food prices around the
world that you've all heard of because of rising energy costs, the corn to ethanol
conversion in the United States, and other things like that has really changed the world
landscape in a lot of interesting ways. It's helped some countries and hurt other countries,
but it certainly has changed the food landscape.
So those are very important political factors, but let's talk about psychology for a minute.
You guys have been trained by your culture to define what constitutes a food. And food is
associated with feelings. Some people eat when they're stressed, some people eat morewhen they're stressed, some people eat less when they're stressed. Some people eat for
comfort, some people get enormous psychological gratification from food, other people
couldn't care less they have to be reminded to eat. What's the difference in there? Now
how many of you let's just get a show of hands, how many of you would say you eat
more when you're stressed? How many of you would say you eat less? Okay it looks like
about a fairly even split which is interesting. We've done some research on this in the past
and found that men and women differ in the response to that question, and of course, the
7/31/2019 Yale Open Course
4/21
level of stress matters and even the type of stress people are feeling. Is it academic stress,
social stress and the like, that depend that determines in part how people respond with
their eating.
So psychology is a big player here. We like certain foods, we have positive associations
with them because of our families and all these
and marketing of course, and all thesefactors come into play in shaping how we feel about food.
Biology is an obvious player. How many of you would say that food can be addictive? Well
maybe three-quarters of you, a lot, that's a lot. Now actually, the science on this is pretty
new and very interesting, and we'll talk about that in the class. But for those of you who
raised your hand just tell me I mean why do you think what makes you believe food
can be addictive? Just somebody tell me. Anybody, go ahead.
Student: If you have withdrawals after eating a certain type of food for a long time.
Professor Kelly Brownell: Okay, so withdrawal is a possibility. If you eat food for a longtime and then you stop, let's say a high sugar diet or something and withdrawal symptoms
occur, well that might mean addiction is occurring. Who else has ideas about that?
Somebody else had their hand up?
A lot of interesting reasons, we've all heard the topic the word chocoholic, sugar addict,
we hear the words withdrawal and things and that becomes an interesting part of the
biology of food. But of course food has this cascade of effects once it enters our body. It
starts even before it goes in our mouth. We sense food coming in, that sets into gear a
series of metabolic and biological processes that are very interesting, and then of course
once the food gets in the body it does lots of interesting things some good things and
some bad things. So we'll talk about what people are eating, we'll talk about what's goodand what's not good and what the optimal diet might be.
Here are a few of the topics that we'll be discussing in the class. First, we'll talk about what
you eat and why, and what the world eats and why. How much is psychology, how much is
biology, how much of it is world politics? All these things are very important players, so
we'll talk about this and discuss what sort of things are shaping your diet, but also the
world's diet and the reasons behind them. We'll talk about whether food can be addictive,
as I mentioned just a moment ago. We'll talk about whether food can promote health; of
course it can if done right, and we'll talk about the specific properties of food that promote
good health and what can be done to increase the opportunity of food to improve the
public's health in a national and international way.
We'll also discuss what we perceive food to be and what we perceive is promoting health
and that may be quite different than what actually promotes health. Are trans fats bad or
trans fats good? If a food never had trans fat in it but it gets labeled as having no trans fat,
does that increase your perception of how good that food is for you? So the perception is
really important here.
7/31/2019 Yale Open Course
5/21
We'll talk about genetically modified foods. Any of you who have come from Europe will
care a lot more about this issue, in all likelihood, than the Americans because it's been a
much hotter topic in Europe. European governments have taken stronger action against
genetically modified foods than is the case of the American government and there is a very
interesting political history to this.
And we'll talk about how modern agriculture affects us. Now most of you probably didn't
come to Yale thinking you were going to learn about farms, but if you take this class you
will, and we'll talk about where food comes from because people have become very
interested and they're becoming ever more interested in the story of their food. They want
to know where it comes from, who grew it in some cases, how many miles it got
transported, what was put on the food as it was being produced, what was given to the
animals or injected into them as the beef was coming out, or the pork, or the chicken, and
these will be very interesting topics to discuss.
And we'll talk a lot about the food industry because of course the food industry is a series
of very important players. They're names that you know, names like Coca-Cola, andMcDonald's, and Pepsi, and Kraft, and companies like this that you've heard of; but there
are also very powerful and important agribusiness companies whose names you may not
have ever heard of who have a big influence on international politics and what that does to
our eating.
Another little pop quiz here, and these aren't trick questions necessarily, but if you had to
guess what the bigger problem was in the developing world, so let's not just say outside the
U.S. but in the developing world, is it hunger and malnutrition, or over nutrition and
obesity? How many would say over nutrition and obesity? A few; and more hunger and
malnutrition? Okay. Incorrect. Believe it or not, the health minister of China recently said,
that over nutrition and obesity and the chronic diseases they cause, is a more significanthealth problem than under-nutrition and the traditional infectious diseases that used to be
the major killers in that country. We're seeing the same thing in all sorts of other countries
around the world. So the nutrition landscape and the physical activity landscape is
changing and is sweeping way across the world. It's interesting to think about what's
driving that and what it means for our health and for international politics.
Here's another little quiz. I'll give you four food companies, and tell me which one you
think is the world's largest. Unilever is one, Kraft is another, Nestle is another, and then
the final one is Coca-Cola. How many of you would guess that Unilever is the world's
largest food company? Maybe ten people. How many would say Kraft? Okay, a few more.
How many would say Nestle? Okay, maybe double the number. How many would sayCoca-Cola? Okay, Coke got the most votes here which is interesting, and in fact Coca-Cola
is an international giant of a company. The Coca-Cola logo is recognized around the
world, there are people in many parts of the developing world who don't trust local water
and hence drink bottled things like Coca-Cola, so they're enormously powerful company,
but the answer to the question is Nestle. They're the world's largest food company. The
second largest food company is Unilever, and the third is Kraft, which is America's largest
food company. And and each of these companies owns thousands and thousands of
7/31/2019 Yale Open Course
6/21
brands and products, so they're very big and very powerful, but it's interesting that we
think that the United States food companies are governing the world market. Well they're
not necessarily, because we only have the number three player in terms of size.
Let me ask another question, if you give this and we'll talk about this in a later lecture,
but if you give this diet to laboratory animal
rats, mice, whatever
it's very commonfor animals to gain a good bit of weight when given access to this diet. Even if they're given
healthy food at the same time, they'll tend to ignore the healthy food and eat a diet like
this. And there are three properties of this diet that help promote overeating and obesity in
laboratory animals. What would you say those three features are?
Student: Sugar.
Professor Kelly Brownell: Okay, sugar is what people usually guess first and that's
correct, that's one of the three. Yes?
Student: High fat.
Professor Kelly Brownell: Okay, fat is number two, so you guys are good so far. Who can
guess what the third might be?
Student: Salt.
Professor Kelly Brownell: Salt is a good guess, but that's not the answer.
Student: Diversity.
Professor Kelly Brownell: Okay, very good variety is the right answer. Most peoplewouldn't think this. But why would a laboratory animal, unaffected by never having
given access to foods like this, not being exposed to marketing or other social influences
that humans are, why would a lab animal seek out a diet, become very overweight, become
nutritionally deficient in some things because it's not eating the healthy food and prefer
these foods to the extent that it becomes unhealthy?
Well there are interesting evolutionary reasons that we'll talk about in the class for that.
So the fact is those lab animals have a hard-wired preference for foods that are high in fat
and high in sugar, primarily because of the energy density that those foods bring to one,
and then the variety is important because you get a mix of nutrients. If you ate the same
food day after day after day, you'd have too many of some nutrients and too little ofothers, and you become nutritionally deficient. So this the seeking out fat, sugar, and
variety is a highly evolved, adaptive evolutionary trait; but in the presence of the modern
food environment that provides access to these things, and to foods like a pop tart with
fifty-six different things in it, the body gets thrown off. The animals become sick from it
and humans become sick from it.
And so one could say that there is a very unfortunate mismatch between our biology and
7/31/2019 Yale Open Course
7/21
our evolution and the modern food environment, because biology of course takes
thousands and thousands, millions of years even to change, but the food environment has
changed relatively recently. The food environment that you're exposed to today is much
different than when I was a boy. When I was a boy the eight ounce Coke was the default
serving, and when I was a child when it was time to have a Coke or a Pepsi you had eight
ounces and the event was over. You didn't go and have another one, or another one, oranother one, and now the default is a twenty-ounce bottle, so you get a sense of how those
sorts of things have changed.
So the environment has changed in a short time but evolution has not and there's a real
mismatch now, which explains why you probably like Haagen-Dazs better than you like
cauliflower. Now why would that be? Well the cauliflower has some nutrients that are
important, but the Haagen-Dazs has immediate value because of the energy it gives you.
And if your body is biologically programmed to defend itself against famine or starvation
which is what humans and animals have faced over all the centuries then you're
going to seek out the energy dense food and that's why those foods taste inherently better.
There's a reason we like fat. There's a reason we like sugar, and there's a real reason whenwe like the two of them together in something like ice cream. So these biological things are
very important.
So there's some very interesting questions we'll address in the class. First of all, what is
food? Now, that seems like kind of a funny question because food is whatever a society
eats. But in fact, it varies a lot from culture to culture, and we'll talk about that during the
class. We'll talk about the story of food. We'll talk about where it comes from, and the
biological, economic, and political reasons that drive food to be certain things, and we'll
talk about what it does to us and for us.
And, probably most important of all is can the food environment change? There areprobably those of you in the class already who are outraged by things like the modern food
environment, how much energy it takes to transport things from place to place, lack of
concern with sustainability and issues like this, and you'd like to see social change. Other
people might have other interests, but we'll talk a lot about social change and what might
be done ultimately to effect the environment.
Right before you guys came to campus there was a tournament, a tennis tournament in
town called The Pilot Pen, which is a lead in tournament to the U.S. Open. And I was out
there and the only place you could really get water, except for a few drinking fountains,
were from the Evian booths and it talks on sand o three fifty for a bottle of water, which
is pretty typical of these places, but what was interesting was the fact that this is shipped infrom France. Well how much sense does it make to ship water to the U.S. from France?
And my guess is that if we did taste tests with all you guys of all the popular bottled
waters, very few people could probably pick out Evian from any other water. And if that's
the case, why in the world would can we justify all that shipping, all the excess energy to
taste, to ship water in from France, rather then just buying something local or drinking
water out of the tap?
7/31/2019 Yale Open Course
8/21
So the food environment can change and can change in productive ways and there are a lot
of signs of this happening. Those of you who are familiar with what's going on in New
York City may know that if you're in a New City restaurant now you cannot eat trans fats,
because trans fats have been banned from the restaurants. There's a very interesting
political history to that. That's a very positive change in the food environment, so we'll talk
about those sort of changes. Okay.
Chapter 2. An Introduction to the Social Construct of Food [00:19:41]
So again, let's talk about what food used to be and what it is now. So we'll take Flaming
Hot Cheetos up there, and later in the class I'll play you a very cute clip from NPR about
kids eating Flaming Hot Cheetos in schools. So the the ingredient label looks like that,
the ingredient label for this looks like that; and so forty-three ingredients in one and one
ingredient in another. It's a really very interesting question about whether that thing on
the left is really food. So if we asked you which of these two things is food, I can imagine
what you'd say. You have Flaming Hot Cheetos and a cockroach.
Now I could probably make some of you very sick to your stomach by having you close
your eyes and imagine eating a cockroach, and if I really walked through what you'd be
experiencing if you did that, you'd be very upset. Well, why is that? I mean probably those
of you I mean I can see you people squirming right now when I just at the mention of
that so I'm not going to go through the process of having you close your eyes and
imagine eating the cockroach. But why would you feel that that's so disgusting? It's not
like you've ever eaten one and had a bad experience and think it's a yucky food. You've
been totally trained by your culture. There are people in the world who do eat
cockroaches, and they would consider that thing on the left not food. So it's totally a social
construction.
If we think about what is food and what isn't food, we have to ask what are the definitions.
Now one of the books that will be assigned for the class is by Michael Pollan called, In
Defense of Food, and he spends some time in that book discussing this issue of what is food
and he has a very interesting take on it. Let's just put together some criteria for what if
you had to say what defines a food, what makes something a food, what would you say?
Okay if it's 'something you can eat,' okay well that makes a cockroach food. Okay what
else defines a food? Yes?
Student: It has nutrients.
Professor Kelly Brownell: It has nutrients. Okay, the cockroach meets the criteria again.Yes?
Student: It's a socially acceptable thing to be eating.
Professor Kelly Brownell: Okay, 'a socially acceptable thing to be eating,' which of course
will change from culture to culture even within a country, so that's very true. Other ideas
7/31/2019 Yale Open Course
9/21
of what might constitute a food?
Student: Energy.
Professor Kelly Brownell: Energy pardon me?
Student: Gives you energy.
Professor Kelly Brownell: 'Gives you energy,' okay. Yes, so that would be the nutrient part
of it. Did I see a hand back here?
Student: I was just going to I don't know if this is one of the things, you can eat it and
you can metabolize it and trap the energy.
Professor Kelly Brownell: Okay, so the body has a way of metabolizing and making use of
the food such that you can get energy or nutrients from it. Okay those are all good
answers. Well I made up some answers too and let's just use these as hypotheticalexamples. One might have to do with where it's from and how it's made so that might tell
us a little bit about whether something should be defined as a food. Its effects would be
next and its social construction would be next, and you guys alluded to all these in your
answers to my question. So first, you might say, well food is something that's found in
nature, that humans have evolved to eat foods that are found in nature. They're out there,
you can gather them, you can hunt them, you can fish them, or you can grow them, you
can do something but it's out there in nature.
Well that's one possible definition of food. Another is how much it's processed and how if
you take things that started out as food like wheat or corn, and then they're processed
many different ways, and things are added to them or done to them that change theirchemical properties, does that affect whether we would consider them food? Its effects, is it
recognized by the body? Can the body ingest this particular item and deal with it in a
reasonable way and not have internal havoc occur? When people are eating foods that are
too high in fat and sugar and they eat these foods consistently, and have other bad
nutrients like trans fats, a lot of bad things happen to the body. The body cannot adapt to
a diet that has certain properties. So if a food belongs to a class of foods that a class of
items that contributes to that internal metabolic havoc, would that be reason to consider it
a non-food?
Then the social construction of course is very important. Do we think something would
taste good and do we define it as a food as part of a culture? So if we go back to theCheetos and the cockroach and we look at our different criteria, and we ask ourselves, is it
found in nature? Well we get a check for the cockroach on that one don't we? Flaming Hot
Cheetos are not found in nature. Is it concocted? Well the cockroach is pretty much its
natural state and you have all the ingredients in the other food. Recognized by the body?
My guess is that eating cockroaches probably won't do internal damage, eating too much
of foods like this certainly will. Is it harmful? Well, I mean a cockroach might be seen as
being harmful because we consider them dirty, disgusting, revolting insects and we don't
7/31/2019 Yale Open Course
10/21
define insects as something we eat, at least in our culture.
Then finally, do we define it as food? Well then we get a check for the Cheetos, does it taste
good? We get a check for the Cheetos as well, but only because we're trained to believe
that one tastes good and the other one doesn't, because in different cultures it would be the
reverse. So you see how these different properties of food affect whether we would evenconsider it a food.
Chapter 3. Understanding Physical and Psychological Distances to Food [00:25:30]
Farms are an interesting part of this. There was a time when people were very close to
their food. They were physically close to it and psychologically close to it. The food was
raised locally. Excuse me. If you think back to New Haven in the 1950s or 1940s, or 1930s,
a lot of the food, much more then is the case today, was grown locally and was sold in
markets and so there might have been one person or one step that resided between you
and your food. You might even see the farmers sometimes who brought the food into
market, and that was certainly true in earlier days.
The distance to food has changed a lot because food has to come in from far greater
distances than used to be the case, and that's changed our relationship with food a lot, into
a distant rather than a close relationship. Here's an example that highlighted in the block
there are the is a farm called Fairview Gardens, that's outside of Los Angeles, in
suburban Los Angeles, and so that's the bracketed part is the farm in 1954. The next
slide shows the farm, same farm and its surroundings in 1998, so you can see that a lot has
happened here. This means that all the area surrounding that Fairview Gardens was
mainly farmland back in the 1950s, all growing food, probably a fair amount of it being
eaten locally by people.
Since that's all been pushed out of the way by development, that means the food has to get
shipped in from larger distances. And it means the people in Los Angeles who were eating
their food, a lot of it shipped in from far away have a distant relationship with it. There's
also a distant psychological relationship with it because we just aren't as concerned as
people used to be about where it came from. But that's changing, and more and more
people do want to know the story of its food. And that story is something we'll talk about
in the class.
By the way, if we go back to this, another big part of disease chronic disease that's
related to diet, is the physical activity part of the equation. As we'll discuss in the class, and
most of you probably know this, your body weight is a function of how many calories youtake in and how many calories you burn off through metabolic processes but also physical
activity. It used to be a lot easier to be physically active then it is today, and we'll discuss
this later in the class, but energy saving devices all over the place. You guys use computers,
I used the typewriter when I started college, so I was burning more calories creating a
paper than you guys have too. That wouldn't seem like a lot of calories but you add that up
across electric garage door openers, and electric toothbrushes, and windows on your car
that you no longer have to crank, and of course you don't have to get up and go across the
7/31/2019 Yale Open Course
11/21
room to change the channel on the television any longer, these things contribute a lot to a
calorie deficit that used to be there's a calorie there's a deficit in how many calories
are burning compared to before and part of that is our environment and the way the
environment is structured.
There's a group of people in the United States and elsewhere who studied something calledthe Built Environment how the environment is built affects how much physical activity
we get. So let's look back at this picture here. Let's just say that you have a child who lives
up here, say in this cul-de-sac, and is friends with a child who lives over here. Now that's
probably not a very long distance and it's the kind of distance where a kid could easily ride
a bike, but of course no parent is going to let a child ride a bike from here to here because
you've got the super highway in the middle, and the only way to get across it would be to
go down here on this very busy road, figure out how to navigate over here, even if there is
a walkway that one could ride a bike, and then maneuver over to here. The introduction to
the super highway, which divides these communities in two, really affects physical activity
a lot. You have- and another example of that that would be true, is let's say you have a
child who lives in this sort of circular area here, who lives here and is friends with a childwho lives here. Then that's not a very long distance, probably easily walkable in a few
minutes; but that child can't be walking through everybody's yard. How do you get there?
You go to go here, here and these could be busy roads, and so parents don't want to do it
because of safety reasons, so you see how when the country used to be laid out in a grid,
like say New York City still is today, then people walk to get to places. But when you have
things like this, which is typical of suburban developments, it affects the physical activity a
lot.
There have been some interesting surveys about people's relationship with food and the
Pugh Foundation did a survey that was published in April of 2006 that asked people how
much
found out what percentage of people really enjoy eating. And in the
from 1989to 2006 there was a pretty significant decline, but even in 1989 the numbers weren't very
high. Now there was probably a time when people enjoyed eating more. They weren't
eating all the time, their eating was confined to three meals a day, it was more likely to be
a social event because the family was together, and the food had more you had a better
personal relationship with food. Why in the world, over that period of time, would people's
relationships with food get even worse?
Well it has to do with our distance from food, our psychological and physical distance
from food, and the fact that we don't appreciate it as much as we do because it's
everywhere all the time and we've been trained to eat outside of the normal meal times.
How many of you have seen the Taco Bell series of advertisements for the fourth meal?Okay, common one, people see that now, well what that means is no longer is a three meal
sufficient; there has to be a fourth. People are eating late at night, they're eating early in
the morning, and they're basically eating all the time. So this is not a very positive sign and
people are having a bad relationship with food. And what can be done to turn it around?
In this same poll, people were asked if they were eating more junk food then they should.
Men and women both said, in pretty high numbers, that they were eating more junk food
then they should. Now you'd hope that it would be a small percentage of the population
7/31/2019 Yale Open Course
12/21
that would be affected by this but it's not. It turns out to be a very high number. We have
to ask why is this? Why are people eating too much junk food? Well, what would be your
guesses? What are the factors? Go ahead.
Student: It's cheap everywhere.
Professor Kelly Brownell: Okay, so availability and cost become two key issues. Yes, and
somebody else had their hand up.
Student: [Inaudible]
Professor Kelly Brownell: Okay.
Student: [Inaudible]
Professor Kelly Brownell: Okay, marketing is a big factor. Yes?
Student: It tastes good.
Professor Kelly Brownell: Tastes good, yeah?
Student: It's easy to get I mean it's easy to make too.
Professor Kelly Brownell: Okay, so it's not only available, it's sort of out there all over the
place, but it's easy. You can be it can be secured easily and it can be made easily in a
microwave or things like that, that's all true. Any other ideas, yes?
Student: Part of the social scene.
Professor Kelly Brownell: Okay, it's part of the social system that we're in. Yes?
Student: Less cleaning, to take care of the dishes and you can just throw it away.
Professor Kelly Brownell: Okay, right it's easy because there's less cleaning, less
preparation and things, right?
Student: Expire [Inaudible]
Professor Kelly Brownell: Okay, that's a very interesting issue about the
the responsewas that because the other food might expire quickly and so that's true; if you're eating
things like fruits and vegetables, they only have a certain amount of life before they go
bad. A lot of these processed foods have very long shelf lives and therefore can be stored
for long periods of time. They can be on store shelves for a long period of time, and that
has to do with the economics of food, especially food available to the poor, which we'll
discuss later. Okay these you guys are all right, everything that I heard was a correct
7/31/2019 Yale Open Course
13/21
answer.
Now the people in this poll were asked the same question and here's what they said, so
75% said that one reason is that it's more convenient, it's what people like to eat, it's
heavily advertised, it's more affordable, people may not know which foods are healthy. So
those are all reasons that you guys mentioned.
Now what you might do about this, let's say that we that you're the Surgeon General or
you're the top health official in some country and you agree with this poll, that people are
eating too much junk food. So what are you going to do about it? Well it kind of depends
on what you think is driving the problem, and each of these things suggest a different level,
different types of things you might do. For example, if it's more convenient should you
change the environment to make the unhealthy food less convenient and make healthy
foods more convenient? That would make sense.
But if this is the reason, it's what people like to eat, what would you do about that? Should
we create a drug that takes away the pleasure from some of these unhealthy foods? Orcould you train people to believe that they're not good for you, etc.? If it's too heavily
advertised, well that screams out for government regulation to cut back on marketing.
We'll talk a lot about marketing and what government can and can't do about it.
If it's more affordable of course you'd want to use an economic intervention. So could you
use taxes and subsidies, for example, to raise the price of foods that you think people
should be eating less of, and lower the price of things you would like people eating more
of? Certainly a possibility. If people don't know which foods are healthy well then it argues
for education but notice that that was almost the lowest ranked thing that people said.
So that would suggest that education is probably not going to get the job done, because
that's not the main driving reason because most people know that they shouldn't eat somuch junk food, but education is what we default to when we think about what to do.
Chapter 4. Marketing and Its Challenge to Altering Food Intake Patterns [00:35:50]
So really, all these things are potentially interesting possibilities and the question is what
makes most sense? Well, we'll sort through all these and discuss what a society might do to
help change food preferences and food intake patterns in the society. We have to ask
ourselves which of these is true. If people are eating too much junk food, which of these is
it? Although most of you would probably say 'well it's all these things are involved, at
least to some extent,' society defaults to certain assumptions about what's driving food
intake and there are some people that default to an environmental explanation of this. It'smarketing, it's economics, it's the environment is set up in such a way to make these foods
very appealing and very attractive to people, and that's why they eat them.
But other people, in fact probably a larger percentage, default to the top option here: that
these are personal health issues rather then public health issues; that people are making
choices about what they eat, if they make bad choices it's their fault. You either need to
implore them to behave differently, you need to coerce them to behave differently, or you
7/31/2019 Yale Open Course
14/21
need to educate them to behave differently. You can see these two camps of thoughts
would generate far different approaches to dealing with dietary crises on an international
scene. We'll walk through these, but of course they're all players.
Now I'm going to show you two advertisements. You may have seen these on TV. One's
from Burger King and one is from KFC, and when I show these to you
we'll talk a lotabout food marketing in the United States, because if you buy the premise that I laid out a
few moments ago, that what we consider food and what we consider to taste good is pretty
much a total social construction. I mean not a complete social construction. For example,
nowhere in the world would people consider eating a rock, because a rock is non-food
across all cultures; but aside from that, there's great variability and so social construction
part of this is very important. That means that somebody has taught us what food is.
Well our family has taught us, our culture has taught us, but the food industry has taught
us too what's food and what's not food. Not only that, they've taught us what constitutes
healthy food and unhealthy food. They've been very influential in teaching us how much of
things we should eat, and look at that in this commercial that you're about to see, and also,the social context of this. Who is deciding what you should eat? And in here, there's a very
male-dominated theme that you'll see pretty quickly, and what you'll see in this is that this
man is being told, and men who watch it, obviously a male-oriented sort of thing that I've
seen watching sporting events and the like. There's a very interesting theme here and it's
not too hard to pick up. So let me play this, so we may need to have high volume on this
because this is pretty this is needs a little more volume (commercial). Now we're not
getting any volume at all. Okay we'll try to correct this problem. It's possible I've got my
own I have my sound turned on. Any idea why we're not getting any volume? Let me
try it again, here we go (commercial).
All right, so what are some of themes when you pick up when you see something like that?I mean there's obviously the manly thing, but what message is being given to the men who
see this? Yes?
Student: Eating healthy is a girl thing to do.
Professor Kelly Brownell: Okay. That eating healthy is a girl thing to do, correct. What
else?
Student: Real men eat meat.
Professor Kelly Brownell: Real men eat meat, that's correct. Yes?
Student: Small portions are bad.
Professor Kelly Brownell: Small portions are bad, that's right. Yes?
Student: Every single man wants to eat this.
7/31/2019 Yale Open Course
15/21
Professor Kelly Brownell: Okay. All men want it because there are a variety of men in
there. Yes?
Student: It's your own decision to eat [Inaudible]
Professor Kelly Brownell: Okay. The man is in charge of his dietary destiny. He's makinghis own decision as you said and no woman is going to tell him to eat quiche or tofu and
that you may have missed it but in the song there we'll show this later in class again
but in the song they say that 'I won't eat quiche anymore' and 'goodbye to tofu' and
things like that. Yes?
Student: A Texas Double Whopper will make you stronger.
Professor Kelly Brownell: Okay, that's right. I mean it's well it's not said directly but
that's inferred isn't it, because all these are they're doing all the muscle kind of things
and they're eating the Texas Double Whopper. They're not showing them keeling over
from a triple bypass surgery, let's say. Yes?
Student: You shouldn't waste your money on healthy food.
Professor Kelly Brownell: Right.
Student: fancy restaurant
Professor Kelly Brownell: Right, because you waste your money if you're buying these
little portions of healthy food. That's exactly right. Yes?
Student: Longer sit down meals are unnecessary.
Professor Kelly Brownell: Okay. Longer sit down meals are unnecessary because you can
just go buy it all of a sudden. Okay, you guys were all right. Isn't it interesting how many
messages are embedded in that short advertisement. And it's done with song, it's done
visually, all sorts of things are embedded in there. I'll show you some other advertisements
later that are oriented to men that make that same argument: that if you're a man, nobody
is going to tell you what to eat. Burger King might, but nobody else. So that becomes as
very interesting theme in these advertisements. That's one, and we could show you dozens
and dozens of these sort of things, and we will over the course of the class; each one of
them very interesting.
The next one I'd like to show you is a KFC ad, and this ran fairly recently. I don't know if
it's still on the air but it ran fairly recently. Look at this and then we'll analyze the themes
in this (commercial).
Okay, so what's embedded in this message? KFC is now is healthy, yes?
7/31/2019 Yale Open Course
16/21
Student: [Inaudible]
Professor Kelly Brownell: Okay, so there was the family theme here that now that KFC is
healthy it becomes something the whole family can enjoy. Yes?
Student: It still tastes good.
Professor Kelly Brownell: Okay, it still tastes good despite not having trans fats. Yes?
Student: [Inaudible]
Professor Kelly Brownell: Okay, you don't have to change things because it's now built
into the healthierquote, "healthier" version. Yes, all the way in the back.
Student: [Inaudible]
Professor Kelly Brownell: Okay, say that again, please?
Student: It's more exciting then your kids.
Professor Kelly Brownell: Food's more exciting then your kids. Yeah, it's there, yes?
Student: Talks about that food is more important then family.
Professor Kelly Brownell: Food's more important then family, right. What about how fast
the sort of lack of control and now I can kind of binge on it or eat it, I don't even have to
wait until the family sits down to eat. Also, it can't be an accident that it's an African
American family depicted in here, so there are a lot of interesting things going on in thislittle video clip.
Now there's a political and business history to this because KFC, as large a company as it
is, is owned by a larger parent company, believe it or not, called Yum Brands. Yum
Brands owns other food-related chains like Taco Bell. But Yum Brands responded in a
very interesting way when the call to remove trans fat first came out. They were pretty
slow off the mark to do something about this, and it was after lawsuits were filed that they
actually made the change.
But here they are boasting about the change! Talking presenting the picture to the
world that, 'well look at this wonderful thing we did, we took out the trans fats and nowyou can eat as much of it as you want.' They don't say it but one could infer that from the
advertisement.
And the fact is, food is healthier if it has less trans fat, but it depends on what fat's
swapped out for it, because if you put a healthier fat in then it's then you get a certain
amount of improvement. But if you put a less healthy fat in you get some improvement but
less. But also, switching out the trans fat in another kind of fat doesn't change the calories
7/31/2019 Yale Open Course
17/21
at all. It still has the same number of calories. And obesity is a huge problem in the United
States, especially in the African American community and other minority communities. So
to imply that now you can eat all you want, you have an issue to free ticket if you will,
some people might consider not the right message.
When we think about the way food is marketed, we have to ask ourselves how were thesemessages framed, who's being targeted, what the message is, and of course what the
impact is. You guys over the course of your life have been exposed to an enormous number
of food messages an enormous number. Far greater than I was when I was a boy. And
they've come in different forms. When I was a boy there was one form and one form only
and it was cartoon it was on Saturday morning cartoons and there was advertisements
for foods on that and it was mainly for sugared cereals. But boy, if you think about your
advertising landscape? So much different then mine was. How is different? Well tell me
some of the ways, how is it different now then my boyhood with just the Saturday morning
cartoons? Do you even realize how much marketing you're exposed to? What forms does it
come in? Go ahead.
Student: Athletes endorsing food companies.
Professor Kelly Brownell: Okay, so you have a variety you have athletes, movie stars,
music celebrities, and people like that who get associated with foods and that's of course
very powerful for kids. The list of athletes that have endorsed some of the food companies
or done marketing for them, so the William sisters, the great tennis players have done fast
food companies. Michael Jordan did fast food companies, Kobe Bryant, and then you of
course get all the cartoon characters like Sponge Bob and other things that over the years
have been associated with a number of these products, so that those attachments are
very important. Yes?
Student: But real people, not just cartoons, you can relate to.
Professor Kelly Brownell: So real people endorsing these sorts of things, that's right.
Michael Phelps, now that he's won all those gold medals, I hear is on Wheaties and
somebody said Frosted Flakes, but I don't know if that's true.
Student: He's passing up Wheaties for Frosted Flakes.
Professor Kelly Brownell: Okay, so there's lots of then these things get coupled like
you're saying, so these are very interesting things.
Think about your marketing landscape and how different it was. So It's on television all
the time, but television used to be almost 100% of the marketing and its share of the
overall marketing burden if you call it that has is going down, but other things have
taken its place. You have billboards; when you guys were in high school, how many of you
had high schools with soft drink machines in them? Okay, almost everybody. Well you
know when you walk past those soft drink machines you're being marketed to even if you
don't buy it because it's that big colorful thing that stands out. That's a form of marketing.
7/31/2019 Yale Open Course
18/21
What about product placements in television shows and movies? There's hardly a movie
that goes by now that doesn't have products inserted and that's all bought and paid for. In
general, if you're watching an action movie and there's a car chase and the trucks and cars
are crashing all over the place, and let's say a Budweiser truck shows up in the scene
somehow, well people are very likely paying for that. Every time a product shows up it's
bought and paid for, for the most part.
Chapter 5. The Importance of Taking a Global View [00:50:11]
A lot of people don't recognize this as marketing, but there are many other forms that
we'll talk about in the class, some of which you probably don't even know about, and it's
some of which you probably see but don't code it as marketing. Your natural defenses that
might provide some kind of a buffer between a commercial message and your behavior,
you have a filter, a screen that helps you interpret these message. The opportunity of
people to control that is going down and down, and down; and the opportunity for parents
to control it is being eroded day, after day, after day. The amount of marketing, the total
marketing burden has gone way up over the years. Of course if you think about what'sbeing marketed, it's not the quiche, it's not the tofu. It's the high calorie, high fat, high
sugar foods for the most part.
We'll talk a lot about marketing. It's very important if we're thinking about food to take a
global view. We have to think about the whole world here. Well why is that important?
Well of course it's an important value to have in general that in order to be good neighbors
in the world we need to understand it, we need to if we're going to be good citizens in
the world we have to know what other people are doing and what's affecting us. But even
if you're totally nation-centric and even if you were only concerned with the United States,
you still have to know what's going on around the world. Why is that? Well one is because
we export a food environment. We export food but we also export norms, we exporteconomics of food, and a number of things that affect the world, and that comes back to
affect us.
The most recent example, as I mentioned before, is the huge spike in food prices around
the world which has created rioting, starvation, major crises in various countries. Some of
that is being forced by the United States and the corn to ethanol conversion program that
has pushed up the price of corn a great deal, pushed down the world supply of corn for
eating, and pushed up world prices. There are other factors involved too like high energy
prices, but certainly U.S. policy is affecting that, but we're also affected by the rest of the
world. Agriculture subsidies in the European Union affect the politics of subsidies here
and that affects the costs of food and what we pay for them at the market. These things areall very important drivers of the diet, so we need to know what's happening globally.
Also, the world's diet is changing to look like that of America. You see these headlines
from scientific journals, and this is just a small sample. 'High intake of added sugar among
Norwegian children and adolescents;' 'Obesity rising at an alarming rate in China;'
'Refined sugar intake in Australian children.' I mean we could I could show these for
the next three weeks non-stop because there's so many papers like this. As I said, when the
7/31/2019 Yale Open Course
19/21
health minister of China says that, over nutrition is a bigger problem then under nutrition,
we're seeing a changing world, so the global view is extremely interesting as we look
around the world.
Here's a slide that shows the projected increase in diabetes in the next twenty-five years.
Now there are two types of diabetes, as you may know, there's Type I Diabetes which is agenetic abnormality that usually shows up in childhood or adolescents where people are
dependent on insulin. That's that accounts for relatively small number of the overall
cases of Type I Diabetes. Type II Diabetes usually has its onset in adulthood that's
beginning to change and is usually created by lifestyle factors: poor diet, physical
inactivity, and obesity. Type II Diabetes used to be called Adult Onset Diabetes, but it's
had to be renamed to Type II Diabetes because kids as young as ten, and nine, and eight
are developing it. This is more alarming then you could ever imagine. A child eight or nine
years old with what used to be called Adult Onset Diabetes. And it's being driven by their
lifestyle, and their diet, and their physical inactivity. Some of those kids will need coronary
bypass surgery in their twenties; some of them will be blind by the time they're thirty.
That's how dire the environment has become.
Let's take a global look at this. In the next twenty-five years the increased the
anticipated increase in diabetes is supposed to be about 37% in the U.S. This is a pretty
alarming number because the rates so high already, one can't imagine it going up by
another third. But in China the numbers look like this, and in India they look this. Now, of
course, there are denominator issues here because we started with a much higher base rate
then these other countries, but if you think about the size of the populations there, the
number of people who are going to become diabetic in the next twenty-five years is really
very frightening. If you collapse data, as we did in this one paper, across all developed and
developing countries here's what we're expecting in the next twenty-five years. This is
going to affect the world; it's going to affect world economies; it's going to affect worldpolitics, the balance of power and things like that, so it's important that we understand it.
And so scenes like this are becoming more and more common around the world. In the
country of China the most widely recognized corporate logo, other than from Chinese
companies, is KFC. The American companies have major reach and major power, and a
lot of the increase in growth in the fast food industry is happening outside the U.S. There
was a paper that I wrote with a colleague in globalization and health, and this quote that I
that I'll show you is from that and I'll read it in case it's a little hard to see. It puts
together the experience with tobacco and the experience with diet, to talk about how
countries might see this problem coming and doing something about it.
"One hopes there is still time for countries to see this coming and take preventive action.
By this we mean poor diet and physical activity and obesity, but history offers a depressing
picture. Smoking is a key example, it took America decades to mobilize after the
catastrophic consequences smoking were clear, but when it did, American tobacco
companies exploited overseas markets, particularly in the developing world. {So we'll
discuss whether the same thing is happening with food and the tobacco industry. The
tobacco history is extremely interesting and relevant here} The tobacco industry in
7/31/2019 Yale Open Course
20/21
countries like China saw the potential as well, and hence, smoking rates like rates of
obesity have been skyrocketing in China and in countries such as Indonesia, Botswana,
and Uruguay. By the year 2025 the number of smokers worldwide is expected to increase
by 45%. {Think about that. As much as we know about tobacco in the United States and
the fact that there are only half the number of people smoking than used to be the case, it's
still expected to rise by 45% worldwide.} By 2030 the deaths attributed to smoking willincrease from four to ten million. The epidemic simply migrates from one part of the
world to another."
So are we having an epidemic of poor diet and what can be done about that? If we're going
to be considerate world citizens what can we do about the area of diet?
Chapter 6. Political Influence and Conflicts around Food [00:57:21]
This has to do a lot with politics, so some of the political issues we'll talk about in the class
will be agriculture subsidies. Again, you probably didn't come expecting to hear about
farming, but farming is where the food starts and we need to understand that world. We'lltalk about the U.S. Department of Agriculture, which at the same time, is supposed to be
helping sell as much food as possible to boost American agriculture, but establishes
nutrition policy. And one can see how those two things might conflict at some point, and
one typically prevails over the other.
We'll talk about the amount of money that goes into Washington to lobby on behalf of the
food industry, and we'll use a few exemplars of that like the National Restaurant
Association which is the major trade association, as you might guess, of the restaurant
industry. They've been very important political players now in the trying to get rid of
trans fats in restaurant movement and also the movement that's happening around the
country to try to get calories put on menus in restaurants.
We'll discuss the research on this and also the politics on it.
It's interesting how our leaders have discussed this. Tony Blair, in 2006, was addressing
the issue of diet and obesity, and here's some of the things he said. And when he said they
he's talking about diseases related to poor diet.
"They're the result of millions of individual decisions at millions of points in time. For
example, 20% of all children in the UK eat no fruits and vegetables in a week. 65% of
adults and half of all children do not take the recommended amount of exercise."
Now who's responsible for this? Is it government's responsibility to correct this or do
people just need to buck up and change their lives in a way that turns these numbers
around? What happens when you start thinking about children? Then who are the
responsible players? Further he says,
"These individual actions lead to collective costs," said Blair, "It's worth pausing for a
7/31/2019 Yale Open Course
21/21
moment to consider the consequences that inaction will bring."
All right, so that means that hidden in there is the idea that these people who are creating
these statistics are costing us all a lot of money.
"Government can't be the only one with responsibility; if it's not the only one with thepower. The responsibility must be shared."
This is actually kind of a moderate position because it talks about government and the
people sharing power here and taking responsibility for change. Very often this personal
responsibility and collective or government responsibility become dichotomies and people
are forced into camps. And that has very important implications for whether government
responds or doesn't respond to these issues. Okay, that's sort of a broad background about
the content of the course.
