Welcome intelligent viewers
to Healthy Living
on Supreme Master
Television.
According to the World
Health Organization,
cancer is one of
the leading causes of death
in the world.
Each year
over 12 million people
across the globe
are diagnosed
with cancer
and 7.6 million
succumb to the disease.
The numbers are projected
to continue rising,
with an estimated
12 million deaths
by 2030.
Today we have the honor
to share the conclusion
of an eight part series
featuring excerpts from
The Cancer Project’s
“Eating Right
for Cancer Survival,”
a two-set DVD
of presentations
by esteemed nutrition
researcher and author
Dr. Neal Barnard, MD
that is a companion
to the book The Cancer
Survivor’s Guide
written by Dr. Barnard
and registered dietician
Jennifer Reilly.
Dr. Barnard, a vegan,
is the president
of The Cancer Project,
a US-based non-profit
organization advancing
cancer prevention and
survival through
distribution of
information on nutrition
and research.
Since its founding in 2004,
the Project has strived
to promote the vegan diet
as the answer to cancer.
The Cancer Project is
a part of
the Physicians Committee
for Responsible Medicine,
a group created by
Dr. Barnard in 1985
that is comprised of
physicians and
concerned citizens
in the US wishing to
improve public health.
The Committee is also
actively involved in
raising awareness
of the benefits
of a plant-based diet
through such projects
as the 21-Day
Vegan Kickstart program
and seeking to amend
federal nutrition guidelines.
Dr. Barnard has served as
the principal investigator
on many clinical studies
examining the links
between diet and health
and his work has been
published in top scientific
and medical journals.
He is often interviewed
by the national media
in the US
for his perspectives
on important issues
in nutrition, health
and medicine.
We are now pleased
to show
Dr. Barnard’s presentation
“Foods and
Breast Cancer Survival,”
a chapter from the
“Eating Right for
Cancer Survival” DVD.
Welcome,
thanks for joining us.
Breast cancer is
a serious epidemic,
and we’re fighting it
on every possible front.
There are better methods
than ever
for detecting cancer, and
we have better treatments
than ever.
But I have to say
as a doctor,
what I like best
is the new method
for preventing cancer,
because if you prevent it,
you never have to treat it,
you never have to
live with this, and the fear
that’s involved with it.
Now we’ve known
for a long period of time,
that diet does make
a big difference.
Some of the first clues
came from Japan.
A woman in Japan,
compared to a woman
in the United States,
she’s less likely
to develop cancer,
and if she’s got cancer,
she’s less likely
to die from it.
She’s more likely to do well,
more likely to survive.
Why would that be?
Well, the first clue was,
well, women in Japan
are thinner,
and that’s important.
Body fat it’s not just there
to store calories, body fat
actually is a living organ,
it makes things,
it makes hormones,
it makes estrogens.
And estrogens
make things grow.
At puberty,
estrogens are responsible
for breast development,
and during all of
a woman’s cycle,
it’s responsible
for the thickening
of the lining of the uterus
every single month.
So if you think of estrogens
as making things grow,
what does that mean
for a cancer cell?
What it means is, it may
make the cancer cell
grow too.
If I take a test-tube, put
breast cancer cells in it,
and add estrogen,
the cancer cells
grow like crazy,
it’s like fertilizer on weeds.
So, let’s say a woman
has more body fat,
she has more estrogen
in her blood,
that’s asking for the cells
to start multiplying
and to spread.
So well, does it work?
If a woman is thinner,
will she actually have
less risk of getting cancer
or will she, if she has it,
will she tend to survive?
The answer is yes.
There was a big study
in Shanghai (China)
that looked,
not just at women who
were quite overweight,
but women who had
different variations,
within what we would
think of as normal weight.
Do you know
the Body Mass Index, BMI?
This is a way of
talking about body weight,
but adjusting it
for your height.
So your ideal weight
is different
if you’re six foot four
versus, say five foot three
okay?
So the way we define it is,
a BMI, a Body Mass Index
under 25, is
what we’re going to call,
normal, healthy weight.
So in the study
in Shanghai,
they had a group of women,
everybody already
had breast cancer,
and the question was,
“If they are heavier
or thinner, would that
affect how they do?”
Here’s what they found.
The women
who had a BMI under 23,
thin women,
their five-year survival
was about 87%.
They then compared them
with the women who
were between 23 and 25,
a little heavier, bit really,
but still
within normal weight.
And their five-year survival
was a little bit less,
about 84%.
And then
they looked at the women
who were over 25.
Not seriously overweight,
but just a little bit
into overweight.
Their five-year survival
was down to 80%.
So the heavier you go,
the more likely you are
to be vulnerable
to this condition, okay?
Well that’s the first thing,
but there’s more to it.
It’s not just the fat
on your body,
it’s the fat on your plate.
And researchers found
that it doesn’t just affect
whether a woman
develops cancer,
it also affects,
whether she does well
or not so well.
At the State University
of New York in Buffalo
(USA), researchers
did an important study.
They brought in
about 900 women,
everybody already
had breast cancer, and
all they did was this:
They looked at their diet,
and then they looked at
who did well, and
who didn’t do so well.
And what they found
was stunning.
The risk of dying
at any point in time
was increased by 40%,
for every thousand grams
of fat the women ate
per month.
Now, let me make
this practical for you.
If I take
a typical American diet,
I throw in all the fat
from the hamburgers
that we might eat,
and the French fries
and the salad oils
and you take all that fat
and you add it up.
You compare that
to a plant based diet,
a vegetarian diet,
so there’s no animal fat
in it, and a diet where
we keep the oils pretty low,
those two diets differ,
by anywhere from 1000
to 1500 grams of fat
every single month.
That’s good for
a 40 to 60% difference
in whether
you are dead or alive
at any single time point
in the future.
So it makes a big difference.
We’ve put this to work,
sometimes
in rather unusual ways.
I was sitting at my desk
one day
and the phone rang.
And a young woman said,
“Dr. Barnard.”
I said, “Yes?”
“I can’t get out of bed.”
I said,
“What’s the problem?”
She said, “This happens
to me every month.
For one day
my cramps are so bad,
I just can’t function,
I can’t get through the day
without taking enormous
amounts of ibuprofen,
and I’m scared about
the side effects, and
I don’t know what to do.
And can you give me
a more powerful
pain medicine
so that I can function.”
I said, “Yes I can.
Let me give you
some painkillers
for a couple of days.”
But it suddenly struck me,
what are
menstrual cramps?
Every single month,
the amount estrogen
in the body rises
and then it falls,
about two weeks in,
that’s when
a woman is ovulating.
And then
the next two weeks the
amount of estrogen rises,
thickening the lining
of the uterus.
What’s it doing that for?
Because the uterus is
the most optimistic organ
in the body.
Every single month
it’s convinced
we’re going to
get pregnant for sure,
so it gets ready.
But then about two weeks
before the end
of the month, it says
“Ah, it didn’t happen.”
So at that point,
the inner lining
of the uterus breaks up,
it’s lost in menstrual flow,
and very maladjusted
chemicals
called prostaglandins
are released.
They cause cramping and
they cause headaches
and they make you
feel crummy.
And so as she’s
talking on the phone,
I’m thinking,
“Wait a minute.
From breast cancer
research we know
that if I cut the fat out
of my diet,
if I bring in the fiber,
I can reduce
the amount of estrogen.
Less estrogen, (means)
less thickening, and
less cramps. Let’s try it.”
So I suggested this to her.
I said, “Let me give you
some painkillers
for a couple of days,
but we want
to do an experiment
for about four weeks.
How about this,
no animal products
in your diet.
If there are
no animal products,
there’s no animal fat.”
And I said,
“And keep the oils low.
Throw away your bottles
of cooking oil
and all that stuff.
Don’t eat the greasy
potato chips and things.
Keep it very basic,
very low in fat.”
She said,
“Well I’ll try anything.”
She calls me up
four weeks later,
“Dr. Barnard,
I just have one question.”
I said, “What’s that?”
She said,
“Why don’t doctors
tell patients about this?”
Her period just sneaked up
on her, virtually
no symptoms at all.
And I thought
that was intriguing.
So I wrote a book
that mentioned this
and I started getting calls
from women who said,
“This is really true!”
And she also found that if
she deviated from her diet
early in the month,
a big bag of potato chips,
something greasy,
she would pay for it
at the end of the month.
So I did a research study
with some colleagues at
Georgetown University
(USA) and we found
indeed it is true.
We brought in a group of
women who had serious
menstrual cramps.
We put them on a diet
that was vegan
and low in fat for
two full menstrual cycles.
It shortened the number
of days of pain.
It shortened the intensity
of the pain.
And PMS (premenstrual
syndrome) symptoms,
like water retention and
bloating and irritability,
all these things got better.
What I’m suggesting
is just this.
The reason
I tell you this story
is we imagine
that our hormones
are controlling us.
That’s true,
but we have a measure
of control over them too.
It’s just we never had
the instruction manual.
Well now
we know how to do it.
Now there are some times
when research
brought us in sort of
the wrong direction.
Do you know
the “Women’s
Health Initiative?”
The “Women’s
Health Initiative” was
a very large and I think,
very well designed
research study but it tested
a rather modest diet.
The idea was if we bring in
a group of women,
in this case,
not quite 50 000 women
and if we reduce
the fat content of their diet,
will that prevent
breast cancer?
Well, they didn’t
make anybody vegetarian
or vegan.
They didn’t really
cut the fat out
to a great degree.
The numbers were like this.
At the beginning
of the study,
the average woman
going into it
was eating about 38%
of her calories from fat.
That’s kind of high.
The national average
is closer to 30%.
Then as time went on,
they were able to reduce
the fat content of their diet
down to about 24%, which
is in the right direction
but it didn’t stay there.
As time went on,
they were going back up
and back up and back up
and by the six year point,
they were back up
to about 29%,
which is very much like
the national average
right now.
Well, what happened?
First of all,
their breast cancer rates
dropped just a little,
about 9%.
So that’s good,
it’s in the right direction
but it’s not strong enough.
With one exception,
progesterone receptor
negative cancer,
that’s one particular type,
dropped 24%.
So that’s good, but here’s
why the diet didn’t work.
They allowed people to
keep eating all the foods
that make
the American diet risky.
They said, have
the leaner cuts of beef;
have chicken
without the skin.
The leanest beef is 29% fat.
Chicken without the skin
is 23%.
Fish, some fish like salmon
is over 50% fat
in a typical cut
of Chinook salmon.
Broccoli is 8%,
beans are 4%,
rice is 1% to 5%.
Those are the foods,
if you really want to
test this in a serious way,
have people eating
the grains and the beans
and the vegetables
and fruits.
So don’t get me wrong,
I think the “Women’s
Health Initiative”
was a great study,
but what it proved wasn’t
that diet doesn’t work.
What it proved is
that small diet changes
do very little.
Let me tell you about
two other studies that
really tackle this problem.
One was called
“The Women’s Intervention
Nutrition Study.”
And what they wanted to do
was to see
if diet makes a difference
after a woman already
has breast cancer.
They brought in
not quite 2,500 women.
Everybody had
breast cancer and
they put them on a diet
that was pretty low in fat,
about 15% of their calories
came from fat.
That’s about half
the American average.
And then they tracked
how they did
as time went on.
What they were
specifically looking for,
was whether a woman
was likely to have
a cancer recurrence
or a new cancer.
Did you know this, that if
a woman has already had
breast cancer,
she’s at higher risk
of getting a new cancer?
So what they found was
the diet worked.
The likelihood of
getting cancer recurrence
or a new cancer
was cut by about 24%
and when they looked at
those that were estrogen
receptor negative, that’s
a particular type of cancer,
they were cut
by about 42%.
So diet, it’s not perfect
but it’s darn good
and we’ll take it.
Now there was
another study called
“The Women’s Healthy
Eating & Living Study”
or “The WHEL Study.”
And they went a step further.
It was low in fat but
they also made a point of
emphasizing vegetables
and fruits and juices
in particular,
like carrot juice
and that sort of thing.
And it wasn’t
quite vegetarian, but it
was going a little further
in that direction.
The study
as we’re recording this now
is not yet finished, but
I want to share with you
some early results
because they’re exciting.
I’ve been suggesting that
if a woman loses weight,
brings in the fiber,
cuts the fat out of her diet,
she’s going to be able to
control her hormones.
Does it work?
They took a sample
of 291 of the women
in the study and
they actually measured
their hormones
at the beginning
and the end.
I’m talking about
estradiol and estrone,
these are the estrogens
in a woman’s blood
and indeed they dropped
quite significantly just
from the diet change alone,
no medicines,
no exercise, nothing,
just the diet change.
But then they went further
and they looked at
the control group
that was not asked
to make any diet changes.
It was a large group
of women,
about 1,500 women
and they varied.
Some of them ate
more vegetables,
some of them ate less
and they did a blood test
for carotenoids,
Beta-carotene
and its cousins.
You can measure that
in a person’s blood.
So if somebody said,
“I eat a lot of vegetables,”
you know,
you can actually tell
if it’s true or not.
So they measured them,
and what they found was
that those women who
had the most carotenoids
in their bloodstream,
meaning
they had been doing it,
they had been eating
the vegetables and fruits,
they had about
a 45% reduction
in their likelihood of
having cancer come back.
So bottom line is this:
We still have good methods
for detecting cancer, we
have pretty good methods
of treating it,
but you know what,
I never want to use them.
I want to see
what we can do
to keep cancer
beyond arm’s length,
and to do that
we need to just change
what’s on our plate.
Thank you very much.
