Why would we be getting cancer younger

0:02

now than before? Yes.

0:05

Cancer

0:07

boy, is it scary. Like, it's the one

0:08

it's the it's the it's the disease that

0:10

you really want to try and prevent as

0:13

much as you can because once you have

0:15

it, it's particularly because it's

0:17

usually caught later, you don't know you

0:19

have it. It's one of those things where

0:20

they're just growing inside of you.

0:22

So,

0:23

this

0:25

cancer in at a at a younger age I have a

0:27

lot of

0:29

ideas why I think cancer is happening,

0:31

you know, earlier and in younger people

0:34

and I think they're pretty

0:35

evidence-based. I'm going to go I'm

0:36

going to go back to the obesity,

0:38

you know, answer because again, you

0:41

know, children are are obese,

0:44

adolescents are obese. We're talking

0:45

about,

0:46

you know, 40% of children or no,

0:49

an increase of 40% over, you know, back

0:51

in like the 1990s. So,

0:54

you're having

0:56

inflammation and you're having, you

0:58

know, oxidative stress and all these

0:59

things that are causing cancer happening

1:02

not in your 40s or 50s. Now, they're

1:04

happening when you're a child. Um

1:06

obesity is associated with 13 different

1:08

types of cancer.

1:10

And 40% of all new cancer diagnoses in

1:14

the United States each year are

1:16

attributed to obesity. It's like half.

1:18

Like, half of all of cancers right now

1:22

are attributed to being obese. That's a

1:24

lot. So, when you think about obesity,

1:26

um happening now in children, what's

1:29

happening is you're the inflammation and

1:32

the oxidative stress, what that means is

1:34

it's able to damage your DNA. And

1:37

for the most part, cancer is an

1:39

age-related disease. There are some

1:40

genetics that can lead to childhood

1:42

cancers. But by and large, cancer hits

1:45

at like 50, 60, 70, 80, right? Like,

1:47

it's an age it's an age-related disease.

1:48

That's most of the time when you're

1:50

getting cancer except for now, it's

1:51

happening in their 50s. Um

1:53

and that is because, you know, you get

1:55

damage and it happens, but it might not

1:57

be in the right part of a gene that can

1:58

cause cancer. So, it's kind of a

2:00

statistics game. You know, it can

2:01

happen. And then as it keeps happening

2:02

year after year after year after year

2:04

after day after day after day, right?

2:05

Eventually, it's going to happen in the

2:06

right part of the genome where a cancer

2:08

cell crops up. And even then, when it's

2:11

one cancer cell, not a big problem

2:13

because we have our first line of

2:14

defense, which is our immune system. Our

2:16

immune system recognizes this cell,

2:18

"Hey, this is not a normal cell." And it

2:20

kills it. The problem is is that obesity

2:24

what happens is not only does it

2:26

increase the things that damage and

2:27

initiate the cancer,

2:29

it it increases growth factors like

2:31

insulin, IGF-1, hormones, estrogen, you

2:35

know, this is very obviously relevant

2:37

for breast cancer.

2:39

Um these growth factors and hormones

2:42

allow cancer cells to survive even when

2:45

they otherwise maybe would die. And

2:47

obesity suppresses the immune system.

2:49

So, what you have going on here is like

2:51

the perfect storm for cancer. And it's

2:54

starting earlier in life, right? And

2:56

that eventually that perfect storm, one

2:59

of those tumor cells is going to slip

3:01

through, it's going to make it, it's

3:02

going to survive, and then it divides

3:04

and it makes two more, and those two

3:06

divide, and it's exponential growth, and

3:07

then you get, you know, over 5, 6 years,

3:10

you have you have, you know, a breast

3:11

tumor, you have a colon cancer tumor.

3:14

So, obesity I think is is a big big

3:16

driver of why younger people are getting

3:18

cancer now. The other thing is diet, and

3:20

it's also very diet and obesity are very

3:22

much intertwined, right? Because

3:25

you can eat a very poor diet, and it can

3:27

lead to obesity. So, diet,

3:30

ultra-processed foods, high refined

3:32

sugar, you know, added sugar foods,

3:34

these these types of foods are also

3:38

playing a role in colon cancer in

3:40

particular.

3:41

Um so,

3:43

you know, there are studies showing

3:44

things like if you're eating processed

3:46

meats, there's things in meats,

3:47

nitrites, that can form nitrosamines,

3:49

they damage colon cells, and you know,

3:51

they're carcinogenic, basically. If

3:53

you're, you know, eating all these

3:55

ultra-processed foods, which takes away

3:57

the fiber. So, the food matrix, if

3:59

you're eating a whole food, you know,

4:01

even if it's like cheese, like when you

4:03

think of fiber, you always think of like

4:04

vegetables, but like food matrix is in

4:07

whole foods. And

4:09

young people are not eating enough of

4:11

fruits and vegetables. They're not

4:12

eating enough whole grains like quinoa,

4:15

amaranth, buckwheat, you know, that

4:16

oats.

4:17

Um 95% of Americans don't meet like the

4:22

fiber intake, which is like it's like 14

4:24

g per 1,000 calories you take in.

4:27

Why is that important? Why is fiber

4:28

important? It's probably one of There's

4:30

pro- It's probably one of the one of

4:31

most well-studied macronutrients in

4:33

terms of preventing colon cancer.

4:35

There's so much evidence. Like you can't

4:37

ignore it. Um

4:39

fiber does a lot of things. One, it

4:41

moves stuff through you quicker. So,

4:42

when you have chemicals in your food

4:44

like nitrites or heterocyclic amines,

4:47

like those are found in meats that are

4:48

charred. So, if you charbroil your meat

4:51

and that blackened taste, you know, that

4:53

some people like, there's something in

4:54

that called heterocyclic amines, which

4:56

are carcinogenic.

4:58

When you eat that food, it sits in your

5:00

gut.

5:01

When it sits in your gut in the colon,

5:03

it damages it. It can cause that

5:05

mutation that can lead to cancer, right?

5:07

Fiber moves stuff through you quicker,

5:09

so it's not sitting around in your gut

5:10

and like being able to damage those

5:12

cells. It's getting it out. It's like in

5:13

and out, in and out, right? The other

5:15

thing is there's different types of

5:16

fiber. So, there's insoluble fiber,

5:18

which is moving it through you, and then

5:20

there's soluble fiber or what's now

5:21

called fermentable fiber. That type of

5:23

fiber is it's basically fuel for the gut

5:28

bacteria in your colon, the gut

5:29

microbiome. A lot of beneficial bacteria

5:32

will eat that soluble fiber, and they

5:35

form a viscous like coating around the

5:38

gut. It prevents those chemicals, it's

5:40

like a barrier, it's like a wall. It's

5:42

preventing the chemicals from being able

5:43

to physically damage your colon cells.

5:46

The other thing it does is it prevents

5:47

your colon from being able to absorb

5:49

microplastics and nanoplastics. Fiber is

5:51

one of the best defenses we have against

5:53

absorbing both microplastics and

5:55

nanoplastics. So, it's really um

5:58

important for helping us prevent a lot

6:01

of the damage that's being done by these

6:03

toxins, these chemicals, whether it's

6:04

plastics or, you know, some of these

6:07

things that are in our ultra-processed

6:08

foods from damaging our colon.

6:11

And so, I think that diet also is a

6:14

really important factor here. Alcohol is

6:16

another one is especially when it comes

6:18

to um breast cancer and also colon

6:20

cancer. But but breast cancer in

6:22

particular. So, a woman's lifetime risk

6:25

for breast cancer

6:26

on average is one in eight. So, if you

6:28

have eight women in a room, one of those

6:30

women is going to be diagnosed with

6:31

breast cancer within her lifetime. Mhm.

6:34

If you add obesity into the mix,

6:36

that's going to increase the chances to

6:37

like one in six. You add in alcohol,

6:40

you're going even up, right? So, all

6:41

these factors, they compound.

6:44

You know, and you're if you start out

6:45

with a one in eight chance, like by

6:46

golly, you better be doing everything

6:48

you can to lower your breast cancer

6:50

risk, not increase it. And so, obesity,

6:52

losing weight is the biggest thing, you

6:54

know, not consuming a lot of alcohol

6:56

also really, really important when it

6:58

comes to lowering your risk for breast

6:59

cancer. So, I think those are three

7:02

important, I would say,

7:04

diet, lifestyle

7:06

factors that are playing a role in

7:08

younger people getting cancer earlier

7:10

and earlier. You said

7:12

increasing fiber leads to you being more

7:15

resilient against uh

7:17

some of these different toxins going in

7:18

your body. Like, what are the main, I

7:21

guess, foods that people are not eating

7:23

to have proper fiber intake? And then,

7:25

how much fiber should they be getting?

7:27

Fiber,

7:28

again, there's multiple types of it. So,

7:30

if you're just wanting the kind of

7:32

insoluble fiber that moves stuff through

7:34

you quickly, which does also play a role

7:36

in preventing your body from absorbing

7:38

plastics, but also, you know, chemicals

7:40

from being able to damage your colon.

7:42

That's found in like every fruit and

7:44

vegetable

7:46

and whole grain, okay? I would say fruit

7:48

and vegetables are great. Whole grains

7:50

are like oats, really, really good.

7:53

The the the fermentable fiber is really

7:55

something unique to fruit skins of

7:59

berries, um mushrooms,

8:02

onions, artichokes, oats,

8:06

resistant starch like green bananas or

8:10

potatoes that are cooked and then

8:11

cooled. This is like you're getting this

8:13

fermentable type of fiber that is a very

8:15

different type of than just the move

8:17

stuff through you, make you poop kind of

8:19

fiber, right? This is the stuff that's

8:20

feeding the gut bacteria. And making

8:23

that gel, that viscous gel. And so you

8:25

want to you want to be eating berries,

8:26

you want to be eating mushrooms, you

8:27

want to be eating like artichoke or

8:29

onion, garlic. You want to be eating um

8:32

oats.

8:33

You want to quinoa, you know, like those

8:35

sorts of things have the fermentable

8:36

type of fiber. You know, the other thing

8:38

that that's doing

8:40

is when the gut bacteria are eating I

8:42

say eating, they're fermenting it,

8:43

right?

8:44

Not only is it making a viscous,

8:47

you know, barrier in your gut,

8:49

it these these bacteria are like little

8:52

chemical factories. They're like little

8:53

pharmaceutical factories inside your

8:54

gut. And they're making compounds called

8:57

short-chain fatty acids, things like

8:59

butyrate, things like acetate,

9:00

propionate. These things are getting

9:02

into your circulation

9:04

and they're acting as signaling

9:06

molecules to the rest of your body. It's

9:08

a way it's a way for the bacteria in

9:10

your gut. It's so interesting like these

9:11

bacteria in your gut can communicate

9:13

with other organs in your body,

9:16

including the immune cells. And so what

9:17

happens is when you're when the gut is

9:19

is fermenting these and making these

9:21

short-chain fatty acids, it's causing

9:23

your immune cells to make a very

9:24

specific type um of immune cells. First,

9:28

it's causing them to make T regulatory

9:30

cells. These are cells that are very

9:31

important for preventing autoimmune

9:32

disease, you know, preventing your your

9:34

body from attacking its own tissue.

9:37

And the other thing they're doing is

9:38

it's causing your immune system to make

9:40

cytotoxic T lymphocytes. These are

9:43

killing cancer cells. So, again, fiber

9:47

is at the is at the core for helping you

9:49

prevent colon cancer so through many

9:51

different ways. And another way is that

9:53

it's actually increasing the production

9:55

of a type of immune cell that kills

9:57

cancer cells. So,

9:59

you ask how much fiber to get. It's like

10:01

literally it's about you know, the men

10:04

and women differ based on their body

10:06

weight. It's also you can think about it

10:08

based on how many calories you consume.

10:09

So, you're supposed to get 14 g for

10:11

every 1,000 calories you consume. I

10:13

think on average like, you know, 25 to

10:16

30 g is a good place to be.

10:20

And

10:22

people are not getting that.

Interactive Summary

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.
