-
>> Gillian: It's sweet.
-
It's seductive.
-
Is it deadly?
-
Tonight the dangers of sugar.
-
>> I think that sugar is a
-
main contributing factor.
-
>> Gillian: Serious new
-
warnings from serious people.
-
>> The more I learn about it,
-
the more it scares me.
-
>> Gillian: Also tonight, what
-
the sugar industry has tried
-
to hide.
-
>> Strategies that I thought
-
the tobacco companies made up
-
back in the 50's, actually
-
some of those, the sugar
-
people had done even before
-
that.
-
(♪♪♪)
-
>> Gillian: When the Breedon
-
family goes shopping, like
-
most Canadians, they try to
-
buy healthy.
-
>> Let's go...
-
Up, up, up.
-
>> Gillian: But, like most
-
Canadians, they don't always
-
succeed.
-
They're busy.
-
Meals have to be quick.
-
And then there's keeping the
-
kids happy.
-
>> It's either Lucky Charms or
-
the Mini Wheat Chocolate?
-
>> No I want the Lucky Ones.
-
>> Okay, Lucky Charms?
-
Okay.
-
>> You want one that looks
-
like half a moon or you want
-
one that looks like a full...
-
>> Gillian: A lot of what they
-
eat is processed.
-
They assume it's nutritious
-
but they've never paid much
-
attention to what's in the
-
food they buy, have no idea
-
how much sugar is hidden in
-
it.
-
>> All right, guys, I want you
-
To kind of start by telling me
-
a little bit about some of the
-
groceries that you got today.
-
>> Gillian: Registered
-
dietician Jacelyn Pritchard is
-
about to help them figure it
-
out.
-
>> Have you guys ever taken a
-
look at any of the nutrition
-
labels or really paid
-
attention...
-
>> The label on this Nesquick
-
cereal says there are 10 grams
-
of sugar in 3/4 of a cup.
-
But who ever just eats 3/4 of
-
a cup?
-
>> How many of those would go
-
into your bowl to make up your
-
bowl of cereal?
-
>> For me?
-
Um...I'd say probably like 8
-
or 9.
-
>> 8?
-
Okay.
-
>> Gillian: That's a lot of
-
cereal....and as Jonathon
-
Breedon is about to find out,
-
an awful lot of added sugar.
-
>> So in your serving of
-
cereal of about 8 of these
-
servings, you're looking at
-
about 20 teaspoons of sugar
-
added.
-
Of non-nutritional value.
-
>> That's a lot.
-
>> Yeah.
-
>> Gillian: So let's start at
-
the beginning.
-
What do we mean when we say
-
sugar?
-
Well, whether it's the white
-
stuff you bake with, or the
-
brown stuff you sprinkle on
-
your oatmeal, whether it's
-
honey, molasses, syrup, maybe
-
the high fructose corn syrup
-
you've heard of.
-
There's a lot of that in
-
things like pop, chemically
-
it's all pretty much the same
-
thing.
-
And we do consume a lot.
-
On average in this country, 26
-
teaspoons of sugar per person,
-
per day.
-
That's 40 kilos a year, the
-
equivalent of 20 bags.
-
It's what sweetens the products
-
and spikes the profits of some
-
of the most powerful,
-
and familiar companies in
-
the world.
-
The food industry is one of
-
the biggest manufacturers in
-
North America, nearly a
-
trillion dollars in sales
-
every year, and it couldn't do
-
it without sugar.
-
(♪♪♪)
-
>> Sugar is one of the essential
-
basic ingredients used in 99%
-
of the processed foods out
-
there.
-
>> Gillian: Former industry
-
executive Bruce Bradley has
-
worked for some of North
-
America's biggest food
-
companies.
-
>> It's something that can
-
drive a lot of taste in the
-
products and a lot of appeal
-
for consumers, so it's one of
-
the basic building blocks.
-
>> Gillian: And make no
-
mistake, the amount of sugar
-
in our food is no accident.
-
The food industry goes to
-
great lengths to figure out
-
what makes us crave a
-
product -- the exact
-
combination of ingredients it
-
calls the "bliss point."
-
>> You know everybody asks
-
what is the bliss point?
-
Dr. Howard Moskowitz, he's a
-
long time food industry
-
consultant, known as Dr. Bliss.
-
>> The best way I can do it is
-
to give you an example.
-
Do you drink coffee with sugar
-
or with milk?
-
>> Gillian: With milk.
-
>> So if you add more and more
-
milk you like it more and more
-
up to a certain point where
-
you like it the most and then
-
add a little bit more milk,
-
and you say oh, it's too milky
-
and my gosh, and add a lot
-
more milk and it's horrid.
-
So it's Goldilocks, it's the
-
middle, it's the best one.
-
It's the level where you like
-
the product the most.
-
>> Gillian: A Harvard trained
-
mathematician Moskowitz uses
-
models to test people's
-
reactions to different
-
versions of a product.
-
Once he's found the bliss
-
point, the product hits the
-
shelves.
-
From soda pop to spaghetti
-
sauce, his magic makes money.
-
>> Everybody wants to sell
-
just a bit more.
-
How do you get that immediate
-
increase in acceptance?
-
Those in the know realize you
-
can add a little sugar.
-
>> Gillian: A little?
-
The first thing to know is
-
that 4 grams of sugar is one
-
teaspoon.
-
So with that in mind, let's
-
look at some products.
-
It's no surprise Coca Cola has
-
a lot of sugar.
-
40 grams a can.
-
That's 10 teaspoons.
-
But much of the sugar we eat
-
is hidden in foods we don't
-
necessarily think of as sweet.
-
This oatmeal, 3 and 3/4
-
teaspoons of sugar a bowl.
-
This vanilla flavoured yogourt,
-
nearly 5 teaspoons in just
-
half a cup.
-
You can find sugar added to
-
bread, soup, all kinds of
-
condiments.
-
Hot dogs.
-
This chicken dinner, labelled
-
Healthy Choice, has
-
5-and-a-half teaspoons of
-
sugar in every serving.
-
Is this the result?
-
There's no question as our
-
consumption of sugars has
-
grown so have our bodies.
-
Canada doesn't keep good
-
statistics so we've used
-
American ones.
-
And those stats raise the
-
troubling question: Are we
-
changing our evolutionary
-
shape.
-
Here's the line showing our
-
sugar consumption for the last
-
50 years.
-
Here's the number of people
-
who've become overweight and
-
obese.
-
Now look at this line, it's
-
for cases of type 2 diabetes.
-
And this one, diseases of the
-
heart.
-
Back in the '80s and '90s we
-
used to blame a lot of those
-
problems on dietary fat.
-
But then we started taking fat
-
out of our foods.
-
Did the incidence of disease
-
go down?
-
No.
-
So that got a lot of doctors
-
and nutritionists asking why.
-
The answer, according to an
-
increasingly vocal group,
-
is sugar.
-
>> Which was worse, the sugar
-
or the fat?
-
The sugar a 1000 times over.
-
>> Gillian: Robert Lustig,
-
doctor, author, medical
-
professor, and one of the
-
leaders of the anti-sugar
-
campaign.
-
>> The fact is, our food
-
supply has been altered and
-
adulterated under our very
-
noses and in plain sight over
-
the past 30 years.
-
>> Gillian: In addition to
-
treating obese kids Lustig is
-
a YouTube sensation.
-
His lecture on sugar has been
-
seen by nearly 4 million
-
people around the world.
-
And he doesn't pull his
-
punches.
-
>> The fat's going down, the
-
sugar's going up and we're all
-
getting sick.
-
>> Gillian: You use words, you
-
use poison, you use toxic.
-
>> Certainly I use those words
-
and I mean them, this is not a
-
hyperbole, this is the real
-
deal.
-
Everyone thinks that the bad
-
effects of sugar are because
-
sugar has empty calories.
-
What I'm saying is no,
-
actually there are lots of
-
things that do have empty
-
calories that are not
-
necessarily poisons.
-
>> Gillian: Poisonous, he says,
-
because of what too much
-
sugar does in our body.
-
So let's take a look at that.
-
Sugar is made up of two
-
molecules: One called glucose,
-
here in blue, the other
-
fructose, in red.
-
When they separate in our gut,
-
the glucose circulates
-
throughout our body feeding
-
our muscles and our brain...
-
but the fructose goes right to
-
our liver.
-
And its in the liver where all
-
kinds of problems begin.
-
>> When you metabolize
-
fructose in excess, your liver
-
has no choice but to turn that
-
energy into liver fat, and
-
that liver fat then causes all
-
of the downstream metabolic
-
diseases.
-
>> Gillian: We'll tell you
-
more about those diseases in a
-
moment.
-
But first let's talk about
-
your brain.
-
Too much fructose, says
-
Lustig, shuts down the part of
-
your brain that tells you when
-
you're full.
-
>> It doesn't get registered
-
by the brain as you're having
-
eaten.
-
So, if you take a kid and prep
-
him with a soft drink and then
-
let him loose at the fast food
-
restaurant, does he eat less
-
or does he eat more?
-
Turns out he eats more.
-
>> I think there's a long way
-
to go before, um, the
-
literature is sorted out.
-
>> Gillian: Phyllis Tanaka
-
speaks for the biggest food
-
companies in Canada.
-
She doesn't buy Dr. Lustig's
-
theories and doesn't think
-
consumers should either.
-
I think it's more important
-
that we step back and look at
-
how do we look for ways to
-
educate and help consumers fit
-
sugar into a healthy dietary
-
pattern.
-
>> Gillian: But the industry
-
sure doesn't make it easy.
-
Look at this breakfast bar.
-
There's sugar near the top of
-
the ingredient list.
-
But there's four more
-
sweeteners.
-
Did you know that chemically
-
they're all the same?
-
Then there's this tomato soup.
-
who knew it would have added
-
sugars too?
-
How is a consumer supposed to
-
know that healthy, old, tomato
-
soup has three-and-a-half
-
teaspoons of sugar in a cup?
-
>> Well, how did you figure it
-
out?
-
By the nutrition facts table.
-
>> Gillian: I figured that out
-
because I've spent a lot of
-
time recently learning about
-
what a gram of sugar is and
-
how to read these labels.
-
Do you think most people know
-
how to do that?
-
>> In the last couple of
-
years, we engaged with Health
-
Canada on a campaign called
-
the nutrition facts education
-
campaign in large part as a
-
commitment to help Canadians
-
understand how to go into the
-
grocery store and make
-
informed choices.
-
>> Gillian: But surely there
-
is a way to warn people who
-
might be interested in this
-
that a cup of this, of this
-
soup, brings you
-
three-and-a-half teaspoons of
-
sugar.
-
>> To what end though?
-
>> Gillian: Well, if they have
-
decided that as part of their
-
healthy diet they want to eat
-
less sugar.
-
>> Well, let me see.
-
Then they would use this same
-
label.
-
>> Gillian: The only
-
information on the label is 14
-
grams of sugar in half a cup.
-
Do you know what that means?
-
You shouldn't have to be a
-
dietitian to figure out how
-
much added sugar you're
-
eating, but it helps.
-
Jaclyn Pritchard has added up
-
all the sugar Jonathon eats in
-
a week.
-
It's pretty scary.
-
>> This is your week's worth
-
of sugar intake then.
-
So this is equivalent to 245
-
teaspoons of sugar.
-
>> That's a lot of sugar.
-
>> Gillian: When we come
-
back, what all that excess
-
sugar might be leading to.
-
(♪♪♪)
-
(♪♪♪)
-
>> That's two grams of sugar.
-
>> Gillian: Having discovered
-
just how much sugar is in
-
their food, the Breedon family
-
is on a purge.
-
>> Okay, the Kraft Zesty
-
Italian has one gram of sugar
-
in this one...
-
>> Gillian: They're still
-
surprised at the kinds of
-
Products that contain sugar.
-
But they're also determined,
-
all of it, out it goes.
-
Of course, they still have
-
to eat.
-
So to help them learn about
-
life beyond processed foods,
-
we've made them a deal.
-
For three weeks we'll provide
-
all of their meals
-
professionally made without
-
any added sugar.
-
They'll stick to the diet and
-
submit to medical tests.
-
>> Lucky Charms ain't so lucky
-
any more.
-
>> Gillian: They're only in
-
their mid-twenties but
-
according to medical standards
-
both Jonathon and Anna are
-
technically obese.
-
Five-year-old Ruby is hovering
-
on the edge.
-
We started our experiment by
-
having their blood
-
tested and analyzed by
-
obesity specialist, Dr. Dan
-
Flanders.
-
The family, he says, is
-
heading for trouble.
-
>> Looking at these results,
-
I would say that I'm very
-
concerned.
-
Quite frankly, if they don't
-
make meaningful change to
-
their lifestyle relatively
-
soon, there's a higher chance
-
that they're heading for a
-
life of lousy quality of life
-
and early death.
-
>> Gillian: Like most of us,
-
getting fatter and sicker,
-
the Breedon's might be
-
forgiven their nutritional
-
ignorance.
-
But the food industry has
-
known, and discussed, links
-
between processed food and
-
disease for decades.
-
It was Minneapolis.
-
1999.
-
Obesity was only an emerging
-
problem back then, when the
-
heads of America's biggest
-
food companies arrived for a
-
rare meeting.
-
Among them, the heads of
-
Kraft, Nabisco, Nestle,
-
Coca-Cola and General Mills.
-
>> These are executives, who
-
normally are fighting each
-
other for space on the grocery
-
store.
-
They don't get together
-
very often.
-
But, in '99, they got together
-
to talk about obesity.
-
>> Gillian: Reporter and
-
author Michael Moss.
-
He described the Minneapolis
-
meeting in his best-selling
-
book.
-
>> And they had been pulled
-
together by a cabal of
-
insiders within the industry,
-
who had increasingly become
-
concerned about, um, both the
-
industry's responsibility for,
-
and culpability for, being
-
blamed for obesity.
-
>> Gillian: They gathered at
-
the Pillsbury Company
-
headquarters, 31st floor.
-
The message they got was
-
uncompromising.
-
And it was delivered by two of
-
their own: Michael Mudd, a top
-
executive at Kraft, and Jim
-
Hill a leading nutrition
-
researcher.
-
In a slide presentation
-
obtained by the Fifth estate
-
the two men gave it to the
-
bosses straight.
-
>> A national epidemic.
-
>> Gillian: There were too
-
many warnings Mudd told
-
them, before drawing a
-
parallel designed to make them
-
uncomfortable.
-
Tobacco companies had recently
-
settled a massive lawsuit in
-
face of evidence their product
-
caused disease.
-
Did the food industry, he
-
asked, want to be next?
-
>> If anyone in the food
-
industry ever doubted there
-
was a slippery slope out
-
there, I imagine that they're
-
beginning distinct sliding
-
sensation right about now.
-
>> Gillian: Graphics drove
-
home the point.
-
Maps showing obesity rates
-
rising and spreading across
-
the country like a rash.
-
>> What are the health
-
implications of all this?
-
Studies show that obese
-
individuals are at a higher
-
risk of developing chronic
-
diseases such as diabetes,
-
heart disease, hypertension
-
and cancer.
-
>> Gillian: Topping the list
-
of contributing factors: The
-
ubiquity of inexpensive,
-
good-tasting, super-sized,
-
energy-dense foods.
-
In other words, the very foods
-
the C.E.O.s were in charge of
-
selling.
-
The two men were hoping for
-
money to study the link
-
between food and obesity.
-
Instead they got a
-
tongue-lashing, starting with
-
Stephen Sanger, the head of
-
General Mills.
-
>> He was rather furious at
-
Mudd for bringing this to them
-
and blaming them for this, and
-
his defence was, "Look, we
-
already offer consumers a
-
choice.
-
If they want low fat this or
-
low sugar that, we have those
-
products in the grocery store.
-
We feel we're already being
-
responsible, both to consumers
-
from a health perspective, um,
-
but also to Wall Street.
-
>> Gillian: In other words,
-
they didn't want to know.
-
Now, it's one thing to silence
-
troublesome voices in their
-
own companies.
-
Michael Mudd eventually left
-
the food industry out of
-
frustration.
-
But the people who profit from
-
sugar have proven themselves
-
very adept at crushing
-
dissenting voices everywhere,
-
including in the halls of
-
science.
-
>> In front of us day by day
-
are increasingly more and more
-
very tempting foods.
-
>> Gillian: His name was John
-
Yudkin, a British nutritionist
-
who in 1972 wrote a book the
-
sugar industry did not like.
-
"Pure White and Deadly" was a
-
culmination of decades of
-
research, according to his son
-
Michael, that led Yudkin to
-
what were then controversial
-
conclusions.
-
>> He started to wonder and
-
late in the 1950s whether
-
sugar might be a culprit in
-
the increase in heart disease.
-
>> Gillian: More significant
-
than fat, which was the
-
prevailing opinion at the time?
-
>> Certainly more significant
-
than fat, certainly more
-
significant than fat, but that
-
sugar was also involved in a
-
number of other undesirable
-
conditions, particularly
-
diabetes and obesity.
-
>> Gillian: That thesis soon
-
put Yudkin in direct conflict
-
with big sugar's biggest
-
apologist.
-
This man, American
-
nutritionist, Ancel Keyes.
-
Keyes would later be exposed
-
as having been funded by the
-
industry, but not before he
-
helped destroy John Yudkin's
-
reputation.
-
>> And as early as the 1950s
-
he had started producing
-
publications suggesting that
-
dietary fat was a problem.
-
>> Gillian: Award winning
-
science writer and author Gary
-
Taubes.
-
>> Keyes successfully managed
-
to taint Yudkin with this smell
-
of quackery.
-
And then on in, anyone else for
-
the next 20, 30 years who did
-
research on sugar was accused
-
of being just like Yudkin.
-
>> There was a systematic
-
campaign to discredit or
-
ignore his work.
-
>> Because of the actions of
-
the sugar industry in the 70s
-
virtually no research was
-
funded.
-
You have this idea that if you
-
study sugar, you're just like
-
Yudkin and he was a quack.
-
>> Gillian: But that's
-
remarkable.
-
I mean, what you're saying is
-
scientific investigation into
-
the link between sugar and
-
disease ground to a halt?
-
>> It ground to a halt.
-
>> Gillian: When we return,
-
the science is back.
-
What happens when you take
-
healthy students and feed them
-
too much sugar?
-
(♪♪♪)
-
(♪♪♪)
-
>> Gillian: It's week one of
-
"The Fifth Estate" Sugar
-
Challenge.
-
>> Just look at recipes that
-
actually help reduce the sugar
-
in your diets.
-
>> Gillian: And the Breedons
-
are getting a cooking lesson.
-
Chef James Smith is teaching
-
that real food, all the fruits
-
and vegetables and grains of a
-
healthy diet, can also be fast
-
and delicious, without any
-
added sugar at all.
-
>> They use specific
-
ingredients that will change
-
up and that will lower the
-
sugar and lower the processed
-
foods in your diet.
-
>> Gillian: And that may prove
-
a good thing, because after
-
decades of silence there is
-
new scientific research
-
linking sugar to all kinds of
-
chronic disease.
-
(wind blowing)
-
>> Gillian: Jonathan's blood
-
work suggests he may be on the
-
verge of getting one.
-
Dr. Dan Flanders.
-
>> His results suggest that
-
he's pre-diabetic.
-
That his levels have been high
-
and that if we don't make some
-
changes to his lifestyle soon,
-
diabetes is coming.
-
>> Gillian: Today in North
-
America it's estimated more
-
than 100 million people are
-
diabetic or pre-diabetic.
-
Dr Robert Lustig is quite sure
-
he knows why.
-
>> So I can actually
-
categorically say to you that
-
sugar is the proximate cause
-
of diabetes worldwide and we
-
have hard and fast data to
-
show that.
-
>> Gillian: His data come from
-
his own study, done over a
-
decade, comparing diabetes
-
rates in 175 countries with
-
peoples' diets.
-
>> And we asked the question:
-
When you adjust for all of
-
the factors that we know are
-
relevant, what about the food
-
supply predicts diabetes
-
rates, worldwide?
-
Answer: Sugar.
-
And only sugar.
-
>> These studies are generally
-
considered a weak level of
-
evidence.
-
A lot of other things have
-
happened at the same time.
-
>> Gillian: Toronto researcher
-
Dr. John Sievenpiper.
-
He argues Lustig's methodology
-
is seriously flawed.
-
>> Methodologists would tell
-
you there's a lot of potential
-
bias, I could give you one
-
example.
-
Over the same time as sugar
-
has gone up, so has bottled
-
water, but there's no real
-
biological plausibility in the
-
link between bottled water and
-
overweight and obesity.
-
So it's not a, I don't think,
-
a sound finding.
-
But we have to be careful in
-
putting too much of the
-
biological plausibility in
-
wanting to believe patterns
-
that we see.
-
>> Gillian: His point is it's
-
hard to know what causes
-
diseases.
-
And ethically can't induce it
-
to find out.
-
But you can test for markers,
-
warning signs that disease may
-
be coming.
-
And that's what they're doing
-
here, at the University of
-
California at Davis.
-
(♪♪♪)
-
(wind blowing)
-
>> Gillian: In this lab,
-
students are the guinea pigs.
-
The scientists are feeding
-
them sugar to figure out if it
-
raises the markers for heart
-
disease.
-
That drink contains 25 percent
-
of her daily calories, as high
-
fructose corn syrup.
-
>> Look at this...
-
>> Gillian: Every time they've
-
run the test, says Dr. Kimber
-
Stanhope, the results have
-
been the same.
-
>> We saw increases in
-
visceral adiposity, that means--
-
>> Gillian: What's that?
-
>> That's the fat within the
-
abdominal region.
-
This is the fat surrounding
-
the liver and the intestines,
-
and the kidney.
-
This is the fat that is
-
associated with increased risk
-
for diabetes and
-
cardiovascular disease.
-
>> Gillian: The Breedons know
-
that fact.
-
Anna and Jonathon have already
-
been diagnosed as having fatty
-
livers, which puts them at
-
risk for raised insulin and
-
triglyceride levels.
-
That's the fat in our blood.
-
When Dr. Stanhope tested the
-
blood of her college guinea
-
pigs, healthy kids with
-
healthy livers, she was
-
shocked by how quickly they
-
saw problems.
-
>> We definitely in two weeks
-
see increases in the risk
-
factors for cardiovascular
-
disease in the blood.
-
>> Gillian: Just in two weeks?
-
>> In two weeks.
-
>> Gillian: But those kinds of
-
studies don't impress
-
everyone.
-
After surveying a number
-
of studies, including
-
Dr. Stanhope's, that look at
-
sugar and heart disease,
-
John Seivenpiper sees no reason
-
for alarm.
-
>> What we find when we look
-
at those trials very carefully
-
is that as long as you match
-
for calories, fructose does
-
not behave differently than
-
does any other form of
-
carbohydrate, namely starches
-
or refined starches and
-
glucose.
-
Now, that's not to say that
-
they're benign, because I
-
don't think we should be
-
having a lot of refined
-
starches or glucose.
-
But it's not behaving any
-
differently.
-
>> Gillian: Stanhope can't
-
speak to the other studies but
-
says she tested for all kinds
-
of things, and it was only the
-
fructose that caused the
-
problems.
-
>> If I had results as strong
-
with regard to a food
-
additive, a brand new food
-
additive and then I started
-
producing these results, they
-
would -- that additive would
-
get pulled pretty quickly.
-
>> Gillian: That's how strong
-
these results are?
-
>> I think they are.
-
(wind blowing)
-
>> Gillian: In the world of
-
cancer research, Lewis Cantley
-
is a rockstar.
-
Five years ago the Cornell
-
University professor was
-
chosen to head a scientific
-
dream team.
-
A group of America's top
-
cancer specialists brought
-
together to supercharge the
-
search for a cure.
-
His findings may not be
-
embraced by everyone but in
-
the cancer world, when Cantley
-
talks, people listen.
-
>> Gillian: Let me ask then,
-
do you believe that sugar
-
consumption causes cancer?
-
>> I think yes.
-
I think that eating too much
-
sugar can definitely increase
-
the probability of cancer, and
-
also make the outcome of
-
people who already have
-
cancer, uh, worse.
-
>> Gillian: So how?
-
Well, let's review what sugar
-
is made of: One molecule
-
glucose and one fructose.
-
We know that when there's too
-
much fructose in the liver, it
-
sets off a chain reaction.
-
The pancreas produces more
-
insulin.
-
What Cantley now believes is
-
that excess insulin changes
-
cancer tumours, telling them to
-
gobble up the glucose.
-
>> What we're now learning is
-
that some of the cancers,
-
particularly those cancers
-
that correlate with obesity
-
and diabetes, often have
-
insulin receptor on the cancer
-
cell.
-
The tumour, by expressing the
-
insulin receptor, tricks the
-
glucose into going into the
-
tumour, rather than the muscle
-
and fat.
-
And as a consequence, the
-
tumour can use that glucose as
-
a fuel to grow.
-
>> Gillian: So if sugar can
-
fuel existing tumours and make
-
them grow, can it also cause
-
tumours to form in the first
-
place?
-
The science on that isn't as
-
clear.
-
Yet.
-
But Cantley is taking no
-
chances.
-
>> It scares me, yes, I think
-
if definitely -- I don't, you
-
know, I will eat fruit, fruit
-
has sugar in it obviously.
-
Uh, but if I can avoid any
-
sugar at all, and any drinks
-
that I drink, or foods, I try
-
to avoid processed foods,
-
'cause it's hard to find one
-
that doesn't have sugar in it.
-
I certainly avoid sugar when I
-
can.
-
(wind blowing)
-
>> Gillian: One of the
-
criticisms of the anti-sugar
-
scientist is that too much of
-
their "evidence" comes from
-
animals, not humans.
-
That said, here at Brown
-
University in Rhode Island
-
they're doing studies they
-
think should make a lot of
-
humans nervous.
-
This rat is perfectly healthy.
-
put him in a vat of water and
-
he finds his way to safety,
-
every time.
-
>> 5.2.
-
>> Gillian: Now, look at this
-
guy.
-
What he's been eating is the
-
equivalent of a North American
-
diet, complete with all the
-
fats and sugars we regularly
-
consume.
-
he doesn't know where to go.
-
his brain has been damaged.
-
>> These rats were totally
-
normal, and then they turned
-
into demented animals.
-
They don't remember they're
-
learning after even a day.
-
And as the challenge gets
-
harder and harder, they fail
-
more and more, just like a
-
human with Alzheimer's
-
disease.
-
>> 36.2.
-
>> Gillian: In this lab the
-
belief now is that Alzheimer's
-
is really diabetes of the
-
brain, linked to insulin
-
levels which can be affected
-
by too much sugar.
-
Professor Suzanne Delamonte.
-
>> Insulin resistance, we now
-
know, can occur in any organ.
-
It can occur in the muscles.
-
that's what diabetes is.
-
It can occur in the liver,
-
that causes fatty liver
-
disease.
-
It can occur in the ovaries,
-
that's polycystic ovary
-
disease.
-
And it can occur in the brain,
-
and we think that's
-
Alzheimer's.
-
>> Gillian: Now it's important
-
to remember that none of this
-
research represents the
-
scientific main stream.
-
The case against sugar has not
-
been proven.
-
Associations on both sides of
-
the border for Alzheimer's,
-
cancer, diabetes, including
-
Health Canada and the FDA
-
they all know about this
-
research and yet but none of
-
them are warning about links
-
between sugar and disease.
-
But there is one important
-
group that is raising the
-
alarm.
-
The American heart association
-
now recommends that people cut
-
back on added sugar,
-
dramatically.
-
Women should have no more than
-
6 teaspoons a day.
-
Men 9.
-
Don't forget the total sugar
-
intake in this country per
-
person is 26 teaspoons a day.
-
And yet, the Canadian food
-
industry remains unimpressed.
-
>> We've talked to people who
-
are quite convinced that there
-
is a relationship, a
-
correlation, between sugar and
-
diabetes and heart disease,
-
cancer, dementia.
-
What happens if those people
-
are right?
-
>> Uh, at this point in time,
-
I'm comfortable saying that
-
the science just isn't there
-
to support a role in chronic
-
disease.
-
>> Gillian: When we come
-
back, government goes on the
-
attack.
-
>> If your kids drink one
-
bottle of soda a day they're
-
eating the equivalent of 50
-
pounds of sugar a year, the
-
equivalent of 50 pounds of
-
sugar from just one soda a day.
-
>> Gillian: And big sugar
-
strikes back.
-
(♪♪♪)
-
>> Everywhere you turn
-
somebody is telling us what we
-
can't eat.
-
(♪♪♪)
-
(♪♪♪)
-
>> Gillian: World wide,
-
there are few industries more
-
powerful than the processed
-
food industry, or the sugar
-
industry that feeds it.
-
And yet for all their power,
-
we know remarkably little
-
about how they work.
-
Cristen Couzens is determined
-
to change that.
-
As a community care dentist in
-
Colorado she'd always been
-
interested in sugar, but it
-
wasn't until she unearthed a
-
stash of documents from a
-
sugar company that had gone
-
out of business, that she got
-
a peek into a very secretive
-
world.
-
>> The first folder that I
-
pulled out opened up to a memo.
-
The blue letterhead of the
-
Sugar Association.
-
And it had the word
-
"confidential" underneath
-
the letterhead.
-
And I just looked at that and I,
-
oh my G-- you know, what have
-
I found?
-
>> Gillian: What she'd found
-
was a directive from the '70s,
-
a memo to industry executives
-
about a newly published
-
scientific white paper; a
-
paper that concluded sugar was
-
not only safe, but important.
-
>> It was clear after reading
-
further that the Sugar
-
Association had funded this
-
white paper called, "Sugar in
-
the Diet of Man," and they
-
were trying to make it appear
-
that it was an independent
-
study.
-
>> Gillian: Among the more
-
than fifteen hundred pages
-
she uncovered, there were
-
some Canadian ones too.
-
An account of a sugar industry
-
meeting in the '70s in
-
Montreal, that included frank
-
talk about heart disease.
-
>> The greatest threat to
-
sugar consumption is in the
-
field of nutrition, it says.
-
More particularly in view of
-
comments that have been
-
recently made on the influence
-
of sugar on atherosclerosis.
-
>> Gillian: So they were
-
worried?
-
>> They were worried, as far
-
back as 1971.
-
>> Gillian: What does that say
-
to you?
-
>> They've known for a long
-
time.
-
>> So I took this paper and
-
crossed out where it said
-
"tobacco" and put in "sugar"
-
and looked to see if I could
-
find similar tactics that the
-
sugar industry was using.
-
>> Gillian: Today Couzens is
-
pursuing her research at the
-
University of California in
-
San Francisco.
-
And she's doing it under the
-
tutelage of someone to whom it
-
all sounds familiar.
-
>> The amazing thing I learned
-
from her was that strategies
-
that I thought the tobacco
-
companies made up back in the
-
50's, actually some of those,
-
the sugar people had done even
-
before that.
-
>> Well, you know now, we have
-
83 million pages of history
-
documents that's on the
-
internet.
-
>> Gillian: Stan Glantz is
-
famous in litigation circles
-
as the man who first
-
publicized secret tobacco
-
industry documents that proved
-
cigarette companies knew their
-
product was dangerous.
-
In the new sugar documents, he
-
sees lots of parallels.
-
>> Well, one parallel is just
-
trying to undermine science.
-
Another one is working to try
-
to attack and intimidate
-
scientists and others who are
-
coming up with results that
-
these big corporate interests
-
don't like.
-
Another one is trying to
-
subvert sensible regulation.
-
>> Gillian: The sugar industry
-
Has decades of practice in
-
that.
-
In 2003 the world health
-
organization in Geneva was
-
looking at a resolution
-
recommending people reduce
-
their sugar intake to just 10
-
percent of what they eat.
-
It had broad appeal among
-
health experts, but then the
-
industry weighed in.
-
>> The sugar industry went to
-
their friends in the US
-
congress and they got these
-
very influential congressmen
-
to write letters and say that
-
this is simply unacceptable.
-
And in fact, that the US
-
would, you know, pull it's
-
funding from the World Health
-
Organization if this report
-
continued.
-
>> Gillian: Five months later
-
the recommendation quietly
-
disappeared.
-
Having seen the movie before,
-
Stan Glantz says we can't
-
afford to let it happen again.
-
>> We wouldn't have a tobacco
-
epidemic if there wasn't a
-
tobacco industry.
-
We wouldn't have an obesity
-
epidemic if there wasn't an
-
industry that was making a lot
-
of money selling sugar and fat
-
and salt and things like that.
-
And to me the bottom line is
-
that one of the key disease
-
vectors for non-communicable
-
diseases is big corporations.
-
And I think we're going to
-
have to have to get these big
-
Corporations under control.
-
>> It has become a bit of a
-
moral issue, when you see the --
-
how far we've come.
-
>> Gillian: Bruce Bradley, who
-
used to help run a number of
-
those corporations, agrees.
-
>> This isn't a blip, this
-
isn't a minor, oh, we just had
-
a minor course correction.
-
We're on a completely wrong
-
trajectory with our health.
-
>> Gillian: What's the answer
-
then?
-
>> I think the honest answer
-
is that we need government to
-
step in and to become an
-
advocate for consumers.
-
>> But sugary drinks are a big
-
reason ...
-
>> Gillian: But look what's
-
happened when governments have
-
tried.
-
Earlier this year New York
-
City passed a law banning
-
super-sized sugary drinks.
-
>> If your kids drink one
-
bottle of soda a day,
-
they're eating the equivalent
-
of 50 pounds of sugar a year,
-
the equivalent of 50 pounds of
-
sugar from just one soda a
-
day.
-
>> Gillian: Industry's
-
response, to ridicule Mayor
-
Michael Bloomberg as an
-
overbearing nanny.
-
The law was later overturned
-
by the courts.
-
(♪♪♪)
-
>> Everywhere you turn somebody
-
is telling us what we can't
-
eat.
-
>> Gillian: But advocates keep
-
on trying.
-
Two weeks ago in Washington,
-
congressmen calling on the
-
government to help consumers
-
by demanding better labels.
-
And at the very least,
-
recommending a daily limit for
-
how much sugar is safe.
-
In Canada and the U.S., those
-
limits exist for other
-
ingredients like fat and
-
sodium.
-
Manufacturers must say what
-
percentage of the recommended
-
daily limit their product
-
contains.
-
But next to sugar, nothing.
-
>> Would your association
-
representing the big food
-
manufacturers in this country
-
would they accept, uh, upper
-
limit of how much sugar
-
Canadians would, should eat?
-
>> I think that's kind of
-
hypothetical because ...
-
>> Gillian: Well, people are
-
putting on the table saying,
-
this is one way to, if you
-
want to curb the amount of
-
sugar people are eating, this
-
is one way to start doing
-
that.
-
>> I think the industry
-
actually has responded to the
-
need for, uh, a diverse supply
-
of foods out in the retail
-
marketplace.
-
>> Across our portfolio of
-
more than 650 beverages we now
-
offer 180 low and no calorie
-
choices.
-
>> Gillian: Today, even
-
Coca-Cola, the world's largest
-
sugar user, knows it can't
-
ignore the health debate
-
anymore.
-
>> We like people to come
-
together with something that
-
concerns all of us, obesity.
-
Coca-cola and every ...
-
>> Gillian: But the bottom
-
line hasn't changed: If you're
-
getting sick from what you
-
eat, it's your fault.
-
>> For people to blame the
-
consumer, to blame the victim
-
in all of this just as the
-
tobacco companies blame the 12
-
year olds they go out and
-
addict, it's just not fair
-
because people aren't given
-
the information that they need
-
if they're trying to make a
-
good choice.
-
>> Gillian: As with tobacco,
-
at some point it will all come
-
down to lives and to dollars.
-
The reckoning, warns Dr.
-
Lustig is coming.
-
>> Bottom line?
-
There will be no money left by
-
the year 2026 for anything
-
else because diabetes will
-
have chewed through all the
-
healthcare dollars.
-
There will be no health care
-
in 13 years here in America if
-
we do nothing and I'm sure
-
Canada is right behind.
-
>> Gillian: For three weeks
-
the Breedons have been eating
-
the food we've supplied.
-
>> How much steak you want,
-
Anna?
-
>> Gillian: They're still
-
eating the kinds of food they
-
like, as much as they like.
-
The only difference none of
-
it's processed and none has
-
added sugar.
-
>> Then eat some of mine because
-
it's not too hot, hot.
-
>> Gillian: So has it made a
-
difference?
-
The moment of truth.
-
In three weeks Jonathon lost
-
one-and-a-half inches around
-
his waist.
-
8-and-a-half pounds.
-
Anna's weight is down too and
-
her waist, where all that
-
dangerous fat can accumulate,
-
is down by 5 inches.
-
And what effect did all that
-
have on their bloodwork?
-
>> I'm Dr. Flanders, nice to
-
meet you.
-
Okay, Jonathan, I am glad to
-
say there's some real signs of
-
things improving.
-
If we have a look at your
-
cholesterol level, it has
-
actually gone down by 10 per
-
cent which is fabulous.
-
Your triglycerides have gone
-
down by 20 per cent.
-
Okay so Anna...
-
>> Gillian: Her results are
-
equally good.
-
And while our three week
-
experiment is far from
-
scientific proof of anything,
-
Dr. Flanders is pleased.
-
>> So this is some evidence
-
that the changes that you've
-
made to your eating
-
are helping to make your body
-
happier, healthier.
-
This is fantastic news.
-
This is really great.
-
>> Well, when we first started
-
the project, I thought the
-
change would be, like, really
-
little.
-
like, I wouldn't see anything.
-
But to see how dramatically
-
its changed, means to me, like,
-
that it's really good.
-
>> It was a big change, at first
-
it was hell, but good results.
-
I'm happy.
