Scientists Just Figured Out Why Cancer Is Rising in Young People
306 segments
Why would we be getting cancer younger
now than before? Yes.
Cancer
boy, is it scary. Like, it's the one
it's the it's the it's the disease that
you really want to try and prevent as
much as you can because once you have
it, it's particularly because it's
usually caught later, you don't know you
have it. It's one of those things where
they're just growing inside of you.
So,
this
cancer in at a at a younger age I have a
lot of
ideas why I think cancer is happening,
you know, earlier and in younger people
and I think they're pretty
evidence-based. I'm going to go I'm
going to go back to the obesity,
you know, answer because again, you
know, children are are obese,
adolescents are obese. We're talking
about,
you know, 40% of children or no,
an increase of 40% over, you know, back
in like the 1990s. So,
you're having
inflammation and you're having, you
know, oxidative stress and all these
things that are causing cancer happening
not in your 40s or 50s. Now, they're
happening when you're a child. Um
obesity is associated with 13 different
types of cancer.
And 40% of all new cancer diagnoses in
the United States each year are
attributed to obesity. It's like half.
Like, half of all of cancers right now
are attributed to being obese. That's a
lot. So, when you think about obesity,
um happening now in children, what's
happening is you're the inflammation and
the oxidative stress, what that means is
it's able to damage your DNA. And
for the most part, cancer is an
age-related disease. There are some
genetics that can lead to childhood
cancers. But by and large, cancer hits
at like 50, 60, 70, 80, right? Like,
it's an age it's an age-related disease.
That's most of the time when you're
getting cancer except for now, it's
happening in their 50s. Um
and that is because, you know, you get
damage and it happens, but it might not
be in the right part of a gene that can
cause cancer. So, it's kind of a
statistics game. You know, it can
happen. And then as it keeps happening
year after year after year after year
after day after day after day, right?
Eventually, it's going to happen in the
right part of the genome where a cancer
cell crops up. And even then, when it's
one cancer cell, not a big problem
because we have our first line of
defense, which is our immune system. Our
immune system recognizes this cell,
"Hey, this is not a normal cell." And it
kills it. The problem is is that obesity
what happens is not only does it
increase the things that damage and
initiate the cancer,
it it increases growth factors like
insulin, IGF-1, hormones, estrogen, you
know, this is very obviously relevant
for breast cancer.
Um these growth factors and hormones
allow cancer cells to survive even when
they otherwise maybe would die. And
obesity suppresses the immune system.
So, what you have going on here is like
the perfect storm for cancer. And it's
starting earlier in life, right? And
that eventually that perfect storm, one
of those tumor cells is going to slip
through, it's going to make it, it's
going to survive, and then it divides
and it makes two more, and those two
divide, and it's exponential growth, and
then you get, you know, over 5, 6 years,
you have you have, you know, a breast
tumor, you have a colon cancer tumor.
So, obesity I think is is a big big
driver of why younger people are getting
cancer now. The other thing is diet, and
it's also very diet and obesity are very
much intertwined, right? Because
you can eat a very poor diet, and it can
lead to obesity. So, diet,
ultra-processed foods, high refined
sugar, you know, added sugar foods,
these these types of foods are also
playing a role in colon cancer in
particular.
Um so,
you know, there are studies showing
things like if you're eating processed
meats, there's things in meats,
nitrites, that can form nitrosamines,
they damage colon cells, and you know,
they're carcinogenic, basically. If
you're, you know, eating all these
ultra-processed foods, which takes away
the fiber. So, the food matrix, if
you're eating a whole food, you know,
even if it's like cheese, like when you
think of fiber, you always think of like
vegetables, but like food matrix is in
whole foods. And
young people are not eating enough of
fruits and vegetables. They're not
eating enough whole grains like quinoa,
amaranth, buckwheat, you know, that
oats.
Um 95% of Americans don't meet like the
fiber intake, which is like it's like 14
g per 1,000 calories you take in.
Why is that important? Why is fiber
important? It's probably one of There's
pro- It's probably one of the one of
most well-studied macronutrients in
terms of preventing colon cancer.
There's so much evidence. Like you can't
ignore it. Um
fiber does a lot of things. One, it
moves stuff through you quicker. So,
when you have chemicals in your food
like nitrites or heterocyclic amines,
like those are found in meats that are
charred. So, if you charbroil your meat
and that blackened taste, you know, that
some people like, there's something in
that called heterocyclic amines, which
are carcinogenic.
When you eat that food, it sits in your
gut.
When it sits in your gut in the colon,
it damages it. It can cause that
mutation that can lead to cancer, right?
Fiber moves stuff through you quicker,
so it's not sitting around in your gut
and like being able to damage those
cells. It's getting it out. It's like in
and out, in and out, right? The other
thing is there's different types of
fiber. So, there's insoluble fiber,
which is moving it through you, and then
there's soluble fiber or what's now
called fermentable fiber. That type of
fiber is it's basically fuel for the gut
bacteria in your colon, the gut
microbiome. A lot of beneficial bacteria
will eat that soluble fiber, and they
form a viscous like coating around the
gut. It prevents those chemicals, it's
like a barrier, it's like a wall. It's
preventing the chemicals from being able
to physically damage your colon cells.
The other thing it does is it prevents
your colon from being able to absorb
microplastics and nanoplastics. Fiber is
one of the best defenses we have against
absorbing both microplastics and
nanoplastics. So, it's really um
important for helping us prevent a lot
of the damage that's being done by these
toxins, these chemicals, whether it's
plastics or, you know, some of these
things that are in our ultra-processed
foods from damaging our colon.
And so, I think that diet also is a
really important factor here. Alcohol is
another one is especially when it comes
to um breast cancer and also colon
cancer. But but breast cancer in
particular. So, a woman's lifetime risk
for breast cancer
on average is one in eight. So, if you
have eight women in a room, one of those
women is going to be diagnosed with
breast cancer within her lifetime. Mhm.
If you add obesity into the mix,
that's going to increase the chances to
like one in six. You add in alcohol,
you're going even up, right? So, all
these factors, they compound.
You know, and you're if you start out
with a one in eight chance, like by
golly, you better be doing everything
you can to lower your breast cancer
risk, not increase it. And so, obesity,
losing weight is the biggest thing, you
know, not consuming a lot of alcohol
also really, really important when it
comes to lowering your risk for breast
cancer. So, I think those are three
important, I would say,
diet, lifestyle
factors that are playing a role in
younger people getting cancer earlier
and earlier. You said
increasing fiber leads to you being more
resilient against uh
some of these different toxins going in
your body. Like, what are the main, I
guess, foods that people are not eating
to have proper fiber intake? And then,
how much fiber should they be getting?
Fiber,
again, there's multiple types of it. So,
if you're just wanting the kind of
insoluble fiber that moves stuff through
you quickly, which does also play a role
in preventing your body from absorbing
plastics, but also, you know, chemicals
from being able to damage your colon.
That's found in like every fruit and
vegetable
and whole grain, okay? I would say fruit
and vegetables are great. Whole grains
are like oats, really, really good.
The the the fermentable fiber is really
something unique to fruit skins of
berries, um mushrooms,
onions, artichokes, oats,
resistant starch like green bananas or
potatoes that are cooked and then
cooled. This is like you're getting this
fermentable type of fiber that is a very
different type of than just the move
stuff through you, make you poop kind of
fiber, right? This is the stuff that's
feeding the gut bacteria. And making
that gel, that viscous gel. And so you
want to you want to be eating berries,
you want to be eating mushrooms, you
want to be eating like artichoke or
onion, garlic. You want to be eating um
oats.
You want to quinoa, you know, like those
sorts of things have the fermentable
type of fiber. You know, the other thing
that that's doing
is when the gut bacteria are eating I
say eating, they're fermenting it,
right?
Not only is it making a viscous,
you know, barrier in your gut,
it these these bacteria are like little
chemical factories. They're like little
pharmaceutical factories inside your
gut. And they're making compounds called
short-chain fatty acids, things like
butyrate, things like acetate,
propionate. These things are getting
into your circulation
and they're acting as signaling
molecules to the rest of your body. It's
a way it's a way for the bacteria in
your gut. It's so interesting like these
bacteria in your gut can communicate
with other organs in your body,
including the immune cells. And so what
happens is when you're when the gut is
is fermenting these and making these
short-chain fatty acids, it's causing
your immune cells to make a very
specific type um of immune cells. First,
it's causing them to make T regulatory
cells. These are cells that are very
important for preventing autoimmune
disease, you know, preventing your your
body from attacking its own tissue.
And the other thing they're doing is
it's causing your immune system to make
cytotoxic T lymphocytes. These are
killing cancer cells. So, again, fiber
is at the is at the core for helping you
prevent colon cancer so through many
different ways. And another way is that
it's actually increasing the production
of a type of immune cell that kills
cancer cells. So,
you ask how much fiber to get. It's like
literally it's about you know, the men
and women differ based on their body
weight. It's also you can think about it
based on how many calories you consume.
So, you're supposed to get 14 g for
every 1,000 calories you consume. I
think on average like, you know, 25 to
30 g is a good place to be.
And
people are not getting that.

This video examines why cancer rates are rising in younger populations, identifying obesity, diet, and lifestyle as key drivers. The speaker explains how obesity triggers inflammation, damages DNA, and creates an environment where cancer cells can thrive while suppressing the immune system's ability to fight them. Furthermore, the importance of fiber is highlighted as a critical defense against colon cancer, acting as a physical barrier in the gut and fostering the production of beneficial compounds by gut bacteria that help regulate the immune system to actively combat cancer cells.
