Q & A
What are the main causes of cancer according to the transcript?
-The main causes of cancer, as discussed in the transcript, are tobacco smoke and diet, with tobacco smoke being the largest contributor at around 35 percent. Diet is also a significant factor, contributing almost as much as tobacco smoke.
What role does tobacco smoke play in causing cancer?
-Tobacco smoke is identified as the biggest contributor to cancer, accounting for approximately 35 percent of cancer cases. This makes it the single most preventable cause of cancer.
How does diet contribute to the development of cancer?
-Diet is a significant factor in the development of cancer, with certain dietary components like sugar and refined carbohydrates providing a fertile environment for cancer cells to grow. The transcript also suggests that obesity is closely linked to cancer development.
What was the initial belief about fiber intake and its relation to cancer?
-Initially, it was believed that a high-fiber diet could help prevent cancer by promoting regular bowel movements and clearing out the bowel. However, this theory was later disproven.
What was the misconception about dietary fat in the 80s and 90s, and was it linked to cancer?
-In the 80s and 90s, there was a widespread belief that dietary fat was harmful and could cause heart disease and possibly cancer. However, subsequent research has shown that this link to cancer was not true.
What role do vitamins play in the development of cancer, according to the studies mentioned in the transcript?
-The transcript mentions that studies on various vitamins (A, D, B, C, E, and others) have shown no significant impact on reducing the incidence of cancer. In fact, some studies suggested that certain vitamin supplements might even increase the risk of cancer.
How has the understanding of cancer as an obesity-related disease evolved?
-The understanding of cancer as an obesity-related disease has evolved significantly since 2003, with research showing that obesity is a significant risk factor for certain types of cancer, such as breast and colorectal cancer.
What is the connection between obesity and cancer, as discussed in the transcript?
-The transcript explains that obesity is now considered a major risk factor for several types of cancer, with the World Health Organization recognizing 13 different types of cancer as obesity-related.
What is the role of genetics in the development of cancer?
-Genetics play a role in the development of cancer, but the transcript emphasizes that lifestyle factors, such as diet and maintaining a normal weight, can significantly reduce the risk of cancer, even in individuals with a genetic predisposition.
How does the transcript describe the impact of lifestyle on cancer risk, particularly among traditionally living societies?
-The transcript discusses how traditionally living societies, such as the Inuit or pre-westernized African communities, had significantly lower rates of cancer. It suggests that adopting a western lifestyle, with changes in diet and habits, has led to an increase in cancer rates.
What dietary changes are suggested in the transcript to reduce the risk of cancer?
-The transcript suggests reducing the intake of sugar, refined carbohydrates, and processed foods, as well as considering the frequency of eating, to create an environment less conducive to cancer growth.
How does the transcript relate the concept of 'fertile soil' to the growth of cancer cells?
-The transcript uses the 'fertile soil' analogy to describe how continuous nutrient signaling from frequent eating can promote the growth of cancer cells, similar to how fertilizer promotes weed growth in an empty field.
Outlines
🚬 Major Causes of Cancer
The first paragraph discusses the primary causes of cancer, emphasizing the role of carcinogens. Tobacco smoke is identified as the leading cause, followed closely by dietary factors. While other potential contributors like radiation and chemicals are acknowledged, their overall impact is much smaller. The conversation highlights the evolving understanding of diet-related cancer causes, debunking past theories about fiber, fats, and vitamins, and points to obesity as a significant factor in modern cancer risk.
🏃♂️ Cancer in Non-Obese Individuals
This paragraph addresses the occurrence of cancer in healthy, non-obese individuals. It explores the complexity of cancer development beyond obesity, including genetic factors and environmental exposures. The text mentions the role of lifestyle changes and how certain genetic predispositions, like the BRCA gene, can increase cancer risk. It also delves into the concept of cancer being a 'seed' that needs a 'fertile soil' to grow, underscoring the interplay between genetics and lifestyle.
🌍 Lifestyle and Cancer Prevention
The third paragraph explores the historical perspective of cancer prevalence among different populations. It discusses how traditional lifestyles in indigenous and non-Westernized societies had lower cancer rates until the adoption of Western diets. The text emphasizes the significant impact of diet and lifestyle on cancer risk, illustrating how changes in these areas could potentially reverse the increase in cancer incidence.
🍽️ Diet's Role in Cancer
This paragraph focuses on specific dietary factors that influence cancer risk. It suggests eliminating or reducing refined sugars, carbohydrates, and processed foods, highlighting how these contribute to creating a 'fertile soil' for cancer. The discussion also touches on the importance of eating habits, including meal frequency, and how constant nutrient intake can promote cancer cell growth.
🥗 Eating Habits and Cancer Growth
The fifth paragraph delves deeper into the role of eating frequency and nutrient signaling in cancer development. It explains how frequent eating and high insulin levels can stimulate cancer cell growth. The text contrasts modern eating patterns with past practices and argues that reducing meal frequency and refining dietary intake can significantly lower cancer growth signals.
🏫 Modern Snacking Culture
This paragraph criticizes the modern culture of constant snacking, particularly among children. It compares past eating habits, where snacking was minimal, to today's frequent eating, which is seen as detrimental to health. The text argues that excessive snacking contributes to the rise in diseases like cancer, pointing out that dietary habits have a more significant impact on disease development than previously thought.

Transcripts
what are the main causes of
cancer as it seems like you hear about
it more and more
recently that so many people are getting
cancer or
um the early stages of cancer what are
the main causes
of cancer yeah that's a great question
and that's something that we've always
been trying to deal with and sometimes
some people say well we don't know what
causes cancer that's sort of a cop-out
because we actually do know
a lot about what causes cancer and these
are things that
cause cancer are called carcinogens and
the world health organization maintains
a huge list of these
carcinogens but if you want to break it
down into what causes cancer
in most people you can look at the sort
of
a couple of studies have looked at the
sort of percentage
contribution of these carcinogens to
um to cancer and the biggest one of
course is
tobacco smoke so that's sort of by far
and away
the the biggest contributor to cancer at
around 35 percent and these estimates
were from 2015
so it's it was higher before when more
people are smoking
but as a contributor to a cancer it's
the biggest
interestingly the second biggest and
almost as big is actually our diet
so it's a huge huge part
of what contributes to cancer in general
and far outstrips so those two are way
above any other causes of cancer so when
you worry about things such as
radiation or you know chemicals
sunscreens and
pesticides and stuff like that they do
cause cancer
but the contribution in a whole
population
is very small so what's interesting
about diet
is that we we know this from our studies
but what part of the diet actually
contributes to a cancer and that's where
things sort of bogged down a lot so
initially in the 70s people talked about
fiber so people thought about oh hey
well
you know maybe if you eat a lot of fiber
what you're going to do is have a lot of
big bowel movements and that's going to
clean out your bowel and you're not
going to get cancer
turns out that wasn't true then the next
thought was hey maybe it's dietary fat
so if you remember the 80s and 90s
there's this huge movement against fat
that
you know all fat is bad for you it
caused the heart disease and all this
sort of stuff much of which is sort of
um been you know overturned at this
point
but there's this thought maybe it causes
cancer too turns out that wasn't true
either
um and then people talked about vitamins
so maybe
cancer is like a vitamin deficiency so
we did many many studies
millions of dollars decades of research
where we would randomize people to say
one group that took
a certain vitamin and one group that
didn't and see if there's any difference
in cancer so we tested vitamin a
didn't work vitamin d b didn't work
folic acid
didn't work vitamin c didn't work
vitamin d didn't work
vitamin e didn't work selenium didn't
work
omega-3 fatty acids didn't work so all
of those supplements
didn't actually make any difference to
the incidence of cancer and the
the so we're sort of stuck at that point
in the mid 2000s saying oh no
it's the diet but what part of the diet
and that's when
it became sort of more and more clear
that this cancer is actually an obesity
related disease
so what happened of course is that in
the 70s 80s and 90s
people didn't really think about it but
then we had this obesity epidemic so it
became
a bigger and bigger problem so uh
obesity in in 2003
when they started to look at the studies
that was the first really definitive
studies that said hey
you know obesity is actually a huge risk
factor as well as type 2 diabetes and
and both of those conditions
will actually increase your risk of
certain types of cancer law
so it really depends on what type of
cancer you're talking like if you're
talking lung cancer obesity plays almost
no role in it right that's smoking
or if you have asbestos which causes
mesothelioma which is a cancer of the
lining of the lung again
obesity plays no role but things like
breast cancer and colorectal cancer
which are sort of
really important cancers they actually
are
obesity related cancers so that was the
sort of big
link and uh to this you know at this
point the world health organization
considers
13 different types of cancer as obesity
related cancers which is huge because
from 2003 we didn't even know like when
i went to medical school
nobody thought obesity caused cancer
really
it's just almost as big as smoking it's
a huge huge thing
so therefore if you know that that's
super powerful because
if you can maintain a normal weight
you're going to reduce just like
stopping smoking right
you're going to reduce your risk of
these types of cancer but aren't there a
lot of
healthy people out there or non-obese
people that also get cancer
oh absolutely because there's a lot of
different things that go on and that's
what i spend the first half of the book
talking about
is how the sort of cancers develop so
it's not just about obesity
just like you can smoke forever and not
get lung cancer but it raises your risk
so same as what what are the other
factors if you're
say you're there's people out there
they're super healthy they're working
out they're
eating well but then they get cancer
they're yeah
under 15 body fat 12 percent body fat
what are those other factors of people
getting cancer
yeah the rest of it we actually know
very little about so we need to know
more about those because certain things
so
smoking and diet are probably your
biggest factors and then there's a whole
there's like a hundred different uh
other risk factors for cancer these are
the other carcinogens that we talked
about
but also things such as you know
background radiation and sun exposure
you know like if you get too much sun
for example so there's all sorts of
other things and genetics plays a role
but one of the big mistakes i think we
made is that we focus so much on the
genetics part of it thinking that well
this is sort of a random mutation
that causes cancer not
sort of which puts the puts the onus on
sort of this random luck
uh sort of uh idea that it's just bad
luck
my parents had this my grandparents had
this gene so i have this i'm gonna get
cancer
yeah exactly and some people think that
that's sort of a death sentence like if
you take
brca which is a certain type of gene for
example
uh so this is the gene that angelina
jolie for example
got diagnosed with her her mom had
cancer i think her
you know an ant had cancer so she got
tested and she had the gene
and people think well for sure you're
going to get you know cancer but it
turns out that
if you look at the incidence of cancer
if you have brca if you have that gene
in like you know in the 30s and 40s and
50s
at risk of breast cancer was like 30
compared to sort of like 80
in modern day america so what's the
difference even though you have the same
genes what's the difference between
those two situations and it comes down
to the lifestyle so the point about
cancer is that
cancer is like a seed so if you have
other genetics
you have the propensity to develop
cancer and this
seed of cancer actually exists in all of
our cells and actually not just all our
cells
but in all multicellular animals have
that sort of seed of cancer
so what's important then is you can't do
anything about the seed but what you can
do something about is the soil
which is that if you provide a fertile
sort of soil for that seed to germinate
then you are going to increase your risk
of developing
this cancer and cancer is not a rare
disease i mean it affects
like one in ten of us one in eight of us
something like that so it's something
that we really have to think about
as we live longer because it is one of
these really important things
it sounds like you know in the next 30
to 60 years if we don't figure out
how to reverse this or solve this or
i guess create bad soil for the seed of
cancer
by creating healthy habits in other ways
it seems like this is going to
accelerate where it was 30
i guess 20 30 years ago or 50 years ago
now and now it's 80
i guess it's going to be even more in 20
to 30 years right oh absolutely and
the the trend is very clear because if
you look at
the uh you know the biggest killers of
americans
it's always been heart disease and
cancer so if you go back sort of to
70 so 50 years ago you look at heart
disease
number one killer of americans that's
heart attacks strokes that kind of thing
cancer was a fairly distant second
but the rate of death from heart disease
has been improving
very very quickly and the rate of
improvement for cancer has been
improving very very very slowly why is
that
it's it's because cancer is a very
complex disease and the way we
think about cancer we just don't know
what it is so
for such a common disease it's a total
mystery
why we get this cancer because if you
think about it it doesn't make any sense
for cancer to develop because it's
actually part of us that is if you
develop breast cancer or colon cancer
for example
that cancer cell was initially derived
from our own
natural cells so what why would it
want to do this that is if you get
cancer
then the cancer grows and then it kills
you and it kills itself in
the in in it kills it yeah why would
this sort of thing ever develop it
doesn't make any sense from a
sort of uh that that looking at it that
way
but most diseases want to spread but
they want to stay alive exactly
exactly like the coronavirus doesn't
want to kill you necessarily it wants to
be able to spread to effect
in fact other people exactly and and in
the in
you know if you sort of by standard it
just kills you uh you know along the way
but that's not its primary purpose
so the point about cancer is that we
have never sort of
understood what this is as a disease
that is if you look at heart disease
heart disease is caused by blockages and
arteries so we develop all kinds of
things so we develop
drugs we develop blood thinners we
develop you know you go in and you use a
balloon to open up the artery
you develop new technologies such as
imaging technologies you develop ways to
monitor patients so
because you know what causes it because
if you don't know what causes something
it's really hard to fix like if you have
a car and all you hear is a random plank
and you don't know what the clanking is
from it's really hard to fix it same
thing with diseases if you have a
disease like covid for example
you know it's a virus well now at least
you have somewhere that you can start
that is okay it's a virus let's
develop a vaccine or let's develop some
antiviral drugs but if you have no idea
what this disease actually is then you
have nowhere to go so that's what i talk
about is how
how we how we think about cancer the
paradigm of cancer as a disease
what causes it you have to first
understand what it is and that's been
the
real mystery the medical mystery is what
is cancer
and the the way we look at cancer has
changed significantly over the last 10
years
right and most people don't even
understand that so it's a very
interesting story from that standard
yeah it's interesting you mentioned you
know the the heart disease
uh i saw dr steven gundry who endorsed
the back of your cancer code book and
he's been on my show a few times and
he's a guy who did
ten thousand heart surgeries and
realized that like the things that he
was doing on the surface level to create
temporary relief
people were coming back in because they
weren't solving the root problem
which was a lot of it around diet and
lifestyle
and that's what i'm hearing you say is
that diet is a massive contributor
to cultivating the seed of
cancer to grow and flourish with the
wrong
side is it possible is it possible in
your mind to reverse cancer
by the right diet and by fasting which
is something you talk about a lot
oh yeah because the thing is that if you
like once you have the cancer it's
really hard because that's sort of like
you know if you if you don't change the
oil in your car then your car breaks
down then you say oh i'm going to start
changing you oh my god well
yeah that's good but you need you know a
lot more than that
it's the same thing once you actually
develop the cancer then it's really hard
to fix from a diet standpoint you really
need the drugs that we've spent
you know millions and billions of
dollars developing over these last 30
years
but in terms of preventing cancer
there's actually no reason why
you couldn't because you can look at
sort of
people who live in a traditional society
for example
so you can take a look at say the inui
or the american indians sort of before
before sort of they became westernized
and or you can look at the african
people before they're sort of
assimilated into a western culture
and interestingly those those
uh peoples were actually considered some
of them were considered
immune to cancer there was so little
cancer
that they thought that the inui for
example or what used to be called the
eskimos
actually could not get cancer so the
university queen's university in
kingston ontario they used to send
an expedition up to the arctic circle
every year to study why these
these inuit couldn't get cancer of
course as they became westernized and
started eating
you know sugar and white flour then they
started getting
all the same cancers that we did in
africa for example this this fellow by
the name of denis burkitt who is a sort
of
a missionary and and doctors when he got
down there he's like
wow in my he was like look at these the
difference the
the people who live traditionally in
africa
get no cancer no colon cancer but the
minute they transition
to a western style civilization with
their foods with their that
you know the whole thing they actually
start to get cancer you don't find
cancer when
when that so it was called actually a
disease of civilization
so all of these diseases obesity
diabetes and cancer
were not found in people living
traditionally so the point is
not that you know one is that they
didn't live as long but the point is
that
if you can find and understand what
makes it
you know protective from them why this
soil is sort of
soil like we all have to seed that the
soil was different
what it is about that if we can
understand that then you can
you can you can reduce your risk
substantially
to the point where your you know your
risk is very low
again as an example if you take a
japanese or chinese woman
from japan or from shanghai and you move
them to san francisco
within a couple of generations the risk
of breast cancer
approximately tripled crazy so it's
crazy
exactly but that's great hope because
you know the root of it that you can go
back to a different way of living
exactly because if you can and remember
shanghai and japan and so on they're
they're
you know modern societies so if you can
understand what it is about the the diet
about the lifestyle that's so important
you could actually take that woman in
san francisco
and reduce her risk of breast cancer by
a third so that's very very powerful
knowledge
so what would you say are the the five
foods we must eliminate
to support us in preventing cancer
what are those five key things here like
and if you can get rid of as much of
this as possible
it's going to really support your
chances
yeah i think that's a good question and
it's um
sort of sugar is probably one of the
very very important things that we
really need to lower because that
really supports it and it gets to how
cancer develops
a lot of the refined foods and people
taught
and the most that we eat like the one
thing we eat more than anything else
tends to be refined carbohydrates
um so you know white bread and that kind
of thing
that's probably the most important thing
uh is the sugar and refined
uh grains refined anything is probably
bad for you
so you know even if you're not talking
about carbohydrates but refined say oils
you should
eat natural oils like eat eat foods that
are sort of in the natural state
and refined uh meats like um you know
it's
you know eating bologna for example
people talk about meat all the time it's
like
there's a big difference between baloney
and you know grass finished beef sort of
thing it's
there's a huge difference because one is
jam packed full of chemicals and
other crap and one is just beef right
and people have been eating beef for
thousands of years
so those are fine foods so refined carbs
but also refined fats and refined
proteins
probably those play a decent role
although the evidence is lower
and then the other thing that is really
important the fifth thing
that's probably very important is likely
uh the frequency that we eat that is
eating all the time provides that
sort of fertile soil so to understand
why this is you have to get back to sort
of how cancer
develops so you have to understand that
cancer almost develops
evolves almost as a separate species
from
us so when you have a breast cancer cell
for example it originated from a normal
breast cell
but after it evolves it it grows or
doesn't grow
depending on growth factors and it's
almost a separate species from us that
is it will grow
and it won't the normal breast cell or a
normal lung cell they will do everything
to
you know play on the team right so
they're always supporting the body
you're part you're a team player those
cancer cells are not team players
basically they're out for themselves
and it's the enemy coming to attack you
that's right it's it's it's like the guy
who's just trying to pad his stats you
know
right it's like you should have passed
it's like yeah
but that's the point that this cancer
cell now is only interested
in its own survival that is it will grow
and it will grow at the expense of its
neighbors so it will keep growing and it
will destroy everything around it
so it will move around for example so a
breast cancer cell will move around the
body
and that's not for the good of the whole
body right it's for the good of itself
it's trying to spread itself around so
you've got to realize that the the
the cancer cell responds as a foreign
organism and it sounds very strange to
say okay we have this foreign organism
almost like an infection
in us but that's actually how our body
sees that cancer that is
our immune system actually detects
is a very powerful um you know it kills
stuff
but it's very powerful so it has to be
reigned in because you don't want it
destroying you know normal parts of the
body so it recognizes certain cells as
foreign and
certain cells itself and cancers are
actually innately
seen as foreign cells so it is a foreign
invader almost that has evolved from us
but during the development of this
cancer
it will grow or not grow depending on
growth signal
so our body has certain nutrient sensors
so nutrient sensors tells our body when
food is available
so when you eat certain certain hormones
like insulin and mtor will go up
that tells our body that food is
available we should grow
right because you don't want your cells
to grow when there's no food
right it's just natural if there's no
food you got to get rid of some of those
extraneous cells so if you have
if you're eating all the time and you're
always
you're always activating these nutrient
sensors you're actually telling your
body
grow grow grow grow so if you eat
six eight times a day you're telling
your body your cells in your body grow
grow grow grow if you eat fewer times
like
three times a day or you do intermittent
fasting if you don't eat at all
what you're going to do is shut down
those growth signals
and this cancer will have a diff more
difficult time
to grow so if you grow breast cancer
cells in the lab for example you can't
do it without insulin
it will actually wither up and die so
therefore if you know that then you can
say well
if i and that's one of the secrets
insulin insulin comes from eating any
food or is this only sugar
mostly it's carbohydrates and protein
so you know but the nutrient sensors
come from
different foods so different foods will
activate different nutrient sensors
but the point is that if you don't eat
like fasting for example
one is you're going to lower your
insulin levels
which will you know lower the growth
overall growth
signaling in our body which is a good
thing for adults and adults growth is
not good
generally you you stay the same size you
don't want to be growing too much
because the you know growth a high
growth environment of course
lets the cancer sort of grow out of
control and that was the secret to why
vitamins for example was not a good
thing
because it's basically growth
it's it's it supports growth of cells
and what they found in a lot of studies
was when they gave people these vitamin
supplements
they actually got more cancer they
didn't get less cancer they got more
cancer
so in fact it's just like if you spray
spread fertilizer on an
empty field you want the grass to grow
but what grows are a bunch of weeds
because you've put down all this
growth signaling uh stuff so therefore
all you get is the weeds
of the body are so are supplements and
vitamins bad for us then
there's no there's no evidence that it's
really bad for you
when you give high doses in these
studies you do get certain ones so folic
acid for example
and beta-carotene which is a precursor
to vitamin a and those two studies
there is actually a suggestion that you
actually get more cancer from them
because in our current situation in
north america most of us are not vitamin
deficient
most of us actually have too much you
actually want to slow down the growth
really and this is why obesity and type
2 diabetes
are so intimately linked with cancer
is because both conditions are
conditions where we have too much
insulin in our body
so we want to lower insulin overall
because
insulin is one of the main causes of the
fertilizer
for cancer to potentially grow exactly
and
and there's several ways to do that one
is to change either the foods that you
eat
and that is the sugar for example the
refined carbohydrates that make up the
bulk of our diet
and the other thing is to change the
frequency with which you eat
because you can affect both things so
just like if you're for example to pay
you know ten dollars and you pay it
every day adds up quickly right if you
have a coffee every day and it's like
you know
five or seven bucks at starbucks every
day every day every day
it adds up so just like that it's not
just the amount that you're paying which
is not much but it's the frequency
right same thing with the foods it's not
just the the amount that you eat or what
it is that you eat it's how often you
eat it
so if you're eating now six eight times
a day well that's a lot worse if you ate
once a day
right that's just basic math like you
can't get around that
and the problem is of course that if you
look at how people eat today
compared to sort of 1970
it's very different so in 1970 people
ate three times a day breakfast lunch
and dinner
no snacks nobody ate snacks back then
now it's a snack culture
like smacking all day exactly and people
say it's good for you people say oh you
should eat multiple times in the day six
times a day it's good for you
but nobody in the history of humanity
has done that before
because we had work to do right it's not
like your great grandparents you know
working in the factory they're taking
off every two hours to make themselves a
little you know
ham sandwich or something right it was
like there's work to do you eat when you
have time
so you know in the 70s it's funny
because
i always say you have breakfast lunch
and dinner and that was it if you wanted
an
after-school snack your mom said no
you're going to ruin your dinner
and if you wanted a bedtime snack she
would have said
no you should ate more at dinner right
right you should have finished your meal
exactly and that was the point and
nobody ate not a lot of desserts and all
that nowadays of course
when you look at the studies people are
eating five six times a day you even
look at schools it's like
you know uh oh you know they're gonna
have breakfast then they're gonna have a
mid-morning snack then they're gonna
have lunch then they're gonna have an
after-school snack
then they're gonna eat dinner and then
if they play soccer in between the
halves of soccer
parents think that you need to feed them
like cookies it's like
okay well you know i played soccer
growing up and nobody chased me around
with a bunch of cookies we had a
great time gradually you didn't need it
right and but that's six times a day
every single day and it's ingrained into
us
um you know a few years ago when my son
was you know going on a trip or
something the school said well you
should pack him two snacks
like why why would you want to give them
a bunch of snacks like
they're not good for you we look at the
root causes of disease and there are
many
right there's environment there's
lifestyle there's genetics
all affect these systems in your body
right but by far the biggest cause is
food
by far and it affects i mean we
what's amazing is it's not it's not just
like a little bit
