Let's say you're trying to find

0:02

some solid information about a serious

0:04

health problem that concerns you high

0:07

blood pressure, diabetes. Yet everywhere you

0:09

look someone's trying to sell you

0:12

something like vitamin, yoga mat, blunders

0:14

drugs while Breathe a sigh of

0:16

relief because all we bring you

0:19

all the facts. Welcome to the

0:21

nutrition facts. Fired! Guess I'm your

0:24

host Doctor Michael Gregor Did you

0:26

know the more than one point

0:28

five billion people. Worldwide suffer from

0:31

hearing loss, but in some cultures

0:33

people retain their hearing and told

0:35

age. Here is our first store

0:37

in the United States. Each live

0:39

hearing loss effects about a quarter

0:41

of those their sixties, more than

0:43

half of those in their seventies,

0:45

and eighty percent of those in

0:47

their eighties. More than ninety five

0:49

percent of Centenarians had been found

0:52

have severe hearing loss because of

0:54

impaired communication. This me leader, social

0:56

isolation, loneliness and depression me even

0:58

threaten one's life didn't associated increase.

1:00

In motor vehicle accidents, what can

1:02

we do to prevent age related

1:04

hearing loss? It said to be

1:06

a natural part of the aging

1:08

process, but that's where we used

1:10

to think about pathological conditions like

1:12

high blood pressure. The vast majority

1:14

of people eventually develop hypertension, just

1:16

like the vast majority will eventually

1:18

lose their hearing, so it must

1:20

just be an inevitable consequence of

1:22

growing old, right? But then it

1:25

was discovered there were rural populations

1:27

living in Africa and Asia that

1:29

Aden lived healthier. Than didn't experience

1:31

in an actual bob rise in

1:33

blood pressure is they aged? So

1:35

what appeared hypertension was more a

1:37

lifestyle choice than an aging effect.

1:39

And the same may be true

1:41

for hearing loss. Them. A

1:43

bond tried living in the Sudanese desert

1:46

was how to retain their hearing and

1:48

old age. Other states and isolated native

1:50

population found that exposure to modern civilization

1:52

per to undercut their hearing advantages. What

1:55

is it about our modern world appears

1:57

to be leading to a loss of

1:59

here. As we grow older,

2:01

age related hearing loss is result

2:03

of the premature death of the

2:06

century Here sales in our inner

2:08

ear which turns vibrations to electric

2:10

signals to the brain. A monster.

2:12

Last, they don't grow back. some

2:15

prevention is critical. The question is

2:17

what's killing them. A. Sudden One

2:19

two thousand and twins found that

2:21

these heard ability vaginally of hearing

2:23

impairments was only twenty five percent.

2:25

So most of risk is due

2:27

to non genetic influences. Risk factors

2:30

include repeated exposure to loud noises.

2:32

Smoking. And auto toxic

2:34

or securing damaging medications Noise exposure

2:36

early in life bridge to render

2:38

the inner ear more vulnerable to

2:41

Egypt. Animal studies suggested social low

2:43

level, but constant noise over sixty

2:45

decimals may also be harmful. This

2:47

is not been demonstrated instruments, but

2:49

if you use a white noise

2:51

generator to sleep, it can't hurt

2:54

to check that it's under fifty.

2:56

Medications known to be auto toxic

2:58

include amino glycoside, Anabolic like Struck

3:00

the My Son and a case.

3:02

In the oh my Son kinda

3:04

my son which are among the

3:07

highest risk medications for here sell

3:09

3:11

times or doors like aspirin or

3:13

Ibuprofen and process and loop directs

3:16

for example of Frozen Minds sold

3:18

at least six have also been

3:20

linked with progressive hearing loss. However,

3:22

the key to the preservation of

3:25

old age Hearing of them the

3:27

Bomb Tribe may be fair dived

3:29

The reason them upon researchers concluded

3:31

that they're busy. It's likely account

3:33

for their lack of major leagues hearing

3:36

loss is because they also appeared to

3:38

like something else: coronary artery disease. what

3:40

kills more of us in the industrialized

3:43

world than anything else doesn't appear to

3:45

touch them at all. Their blood vs

3:47

are also perfect their whole lives, and

3:50

Robin Ten were seventy into their seventies.

3:52

While we're on average become hypertensive exceeding

3:54

one thirty, I'm really starting in our

3:57

forties and no wonder their diet is

3:59

almost. The of animal protein and

4:01

centered around whole grains so they suggested

4:03

in addition to the absence of loud

4:06

noise that atherosclerosis clogging the small blood

4:08

vessels feeding their inner ears maybe the

4:10

underlying cause of easily ended hearing loss

4:13

and most of the rest of the

4:15

world mud? You don't know. Until

4:17

you pointed to the test which

4:20

are governed next after dealing with

4:22

a sudden shown to slow age

4:25

related hearing loss. Healthier

4:28

diets are so she was a

4:30

significant lower risk of hearing loss

4:32

and for all three Die Claudy

4:34

scoring system to these researchers used

4:36

of wins of meat was most

4:38

strongly associated with lower risk. The

4:40

labonte who preserve their hearing and

4:42

4:44

also weren't eating sugar in Yonkers

4:46

linger almost total absence of dental

4:48

cavities. a cyclist died of refined

4:51

carbs is also associate with developing

4:53

age limp hearing loss if it's

4:55

so much sugar spikes that would

4:57

explain my diabetic and pre die

4:59

banks are also a higher risk.

5:01

Isn't a whole grains sorghum which

5:03

is the center of them? A

5:05

bond died as a particularly low

5:07

5:09

5:11

four percent lower rise and blood

5:14

sugar compared whole wheat. Impaired blood

5:16

circulation may also explain how noise

5:18

damages the interviewer is. Loud noises

5:20

cause construction of the company blood

5:22

vessels. This may also help clarify

5:24

the link between obesity and hearing

5:26

loss. Excess weight. Images be

5:28

a proxy for unhealthier dies, but

5:30

that's pro inflammatory state of obesity

5:33

can itself leader vascular dysfunction. Measures

5:35

of systemic inflammation seem to directly

5:38

correlate with age related hearing loss

5:40

As to measures of oxidative stress

5:42

in my video on brain inflammation.

5:45

I introduce the answer some defense

5:52

Those born of the genetic variant

5:54

Nerf to that doesn't and code

5:59

is it. The open periods during

implicating the role of free radicals in

6:03

the process of hearing loss, you can

6:05

look in the back of people's eyes

6:08

6:12

dioxins constrained in greens and correlate that

6:14

with superior hearing. The.

6:17

Population date on and arson. Intake and

6:19

hearing loss is mixed though. Take Vitamin

6:21

C for example some silly show

6:23

that higher been seen take associate with

6:26

better hearing mud Others failed to

6:28

find any significant connections. Still a way

6:30

to tell them to our sins.

6:32

Help or not, you know the drill

6:34

is to. For them to

6:36

the tests adding into our since

6:38

the days of rats seems to

6:40

help prevent age related rak hearing

6:42

loss. but doing the same thing

6:44

and mice doesn't appear to help.

6:46

The most exciting pre clinical data

6:48

may be a study which aged

6:50

rats randomized the added blueberries look

6:52

like they had a reversal in

6:54

hearing deficits, in fact ending up

6:57

better than the younger rat. Oh

6:59

wait, other here so don't regenerate.

7:01

Our ability to hear doesn't just

7:03

have to do with our ears,

7:05

but our blame. As we age

7:07

or auditory cortex in the temporal

7:09

lobe for brains lose some of

7:11

it's ability to discriminate and understand

7:13

speech even in a quiet environment.

7:16

We don't just need a sense

7:18

sounds but make sense out of

7:20

them for that swear blueberry seem

7:22

to come in reversing the age

7:24

related cognitive deficits in on tory

7:27

process. but what about in people?

7:29

Their studies lacking control groups that

7:31

documented improvements in hearing loss giving

7:33

people and they are consultants like.

7:35

Vitamins, Easy and awful podcast and

7:37

bowl when properly point to the death

7:40

and ran my mind. Placebo controlled trial

7:42

of a whole list of and options

7:44

to some month for a lot no

7:47

effect on any of the measured hearing

7:49

aspect. Is. There any supplement

7:51

7:53

an older adults at yes. Folic

7:56

Acid. The. Supplements form of

7:58

fully from. Straighten beans and

8:01

grains. Some observational studies have found that

8:03

the higher levels of fall in the

8:05

blood seem to correlate with better hearing,

8:08

but maybe that's just a milk or

8:10

of eating healthier diet general celts. Dutch

8:12

researchers set out on an ambitious three

8:15

or double blind placebo controlled trial randomized

8:17

more than seven hundred older men or

8:19

women to take his hundred micrograms of

8:22

full guess a day or and indistinguishable

8:24

placebo. Excitingly, those who have been taken

8:26

a forward acid suffered significant less decline

8:29

and hearing it. Speech frequencies. The effect

8:31

size was rather small, such as one

8:33

might expect of proportion of men For

8:35

example would be hearing aid candidates at

8:38

age seventy five. My drop from thirty

8:40

three percent to twenty two percent with

8:42

vote acid supplementation. I'm also not. The

8:45

study was done in the Netherlands. We're

8:47

at the time the food supply was

8:49

not fortified with forecast in the Us.

8:52

Who forecasted for case has been mandated

8:54

in refined grain products for decades. Some

8:56

clear how much additional benefits supplements might

8:58

add. Regardless, the healthiest

9:01

sources are dark green leafy vegetables

9:03

and legumes, a cup of cooked

9:05

lentils as and ninety percent of

9:07

adult daily me. Finally,

9:10

Today we hear about the results

9:12

of a diet that make slow

9:15

or even reverse hearing loss. A

9:18

twenty twenty one scalding review on

9:20

the wrong nutrition and the development

9:22

of prevention of easily hearing loss

9:24

screamed thousands of a person's included

9:26

the died switch and saturated fat

9:28

and cholesterol have deleterious effects on

9:30

string that could be prevented by

9:32

lower consumption. The case of the

9:34

My Bonnet noted before makes for

9:36

a compelling story, but I'm what

9:38

exactly are they basing their conclusion.

9:40

It's true that in a laboratory

9:42

animals you can prove and randomize

9:44

rash to added saturated fat or

9:46

chinchilla The added dietary cholesterol. Scientists

9:48

can show atherosclerosis inducing guys exacerbate

9:51

in are your damage and hearing

9:53

loss even without noise exposure. but

9:55

that doesn't necessarily mean the same

9:58

is true and people. The

10:00

real coaching deputy Mayor Logical data of

10:02

resembles to the thousands of twins was

10:05

able to draw significant link between high

10:07

cholesterol died in hearing impairment in the

10:09

Blue Mountains Hearing Study which enrolled thousands

10:11

of older men and women, the stone

10:13

age related hearing last dietary cholesterol was

10:16

the neutering component most associated with hearing

10:18

loss losing my two eggs worth of

10:20

close road. They had thirty four percent

10:22

greater odds of hearing loss compared to

10:25

those only getting both single and worth

10:27

consistent with a vascular cause Those on

10:29

Staten some. Briskly, those at higher doses appeared

10:31

be a lower risk. The researchers

10:33

suggest a cyclist role in take me

10:36

interfere with the circulation within the inner

10:38

ear itself or as her slot. A

10:40

complaint or changes could reduce blood flow

10:42

to the tiny arteries feeding the inner

10:44

ear. But how about looking inside the

10:47

arteries to see of this is actually

10:49

true. Extent and

10:51

severity of coronary artery disease in the

10:53

heart as determined by angiogram was found

10:55

a closely correlated to searing loss. Since

10:57

atherosclerosis as a systemic disease affecting the

11:00

entire arterial tree, this has relevance for

11:02

the arteries feeding the inner ear. The

11:04

same was home for the amount of

11:06

Asses Slavic plaque, sound, the crowded orders

11:09

in the next, the great of a

11:11

plaque, the poor in the hearing, and

11:13

more plaque. They found a greater risk

11:15

of further hearing impairment measured on the

11:17

subsequent five years. Getting

11:19

closer. But how about the arteries

11:22

that directly supply the inner ear?

11:24

Or the autopsy data suggests a sclerotic

11:26

changes the blood vessels of older ears

11:29

contribute to in we're degeneration and these

11:31

days direct imaging studies correlate the degree

11:33

of your loss with atherosclerotic narrowing. Of

11:35

those in are your orders now all

11:37

we need isn't interventional trial to wrap

11:39

it all up in a both yes

11:42

sir high cholesterol hi saturated fat guys

11:44

have been shown to kill off those

11:46

critical interior cells and cause hearing loss

11:48

and a lab animals but of not

11:50

like you can lock hundreds of people

11:52

up for a few years and for

11:55

some meet different maps assessor in a

11:57

van see what happens to their hearing.

11:59

Ah old. You can, And

12:01

they did. The Finish

12:04

Mental Hospital Study in Nineteen sixty

12:06

one of two mental hospitals near

12:08

Helsinki had the menus change to

12:10

decrease their intake of saturated animal

12:12

fat. Then after a few years

12:14

the to Ask will switch their

12:16

menus over. It was one of

12:18

the first and irrational trials of

12:20

it's kind, suggesting that he could

12:22

decrease heart disease deaths by decreasing

12:24

saturated fat intake. Ah, but what

12:26

happened to their Sera? It followed

12:28

the exact same pattern as their

12:30

heart disease got worse. so did

12:32

they are. Here and and then when

12:35

the hospital switched the reverse happened and

12:37

answered by a little. Those in their

12:39

fifties in the lower center is a

12:41

hospital and of was significantly better hearing

12:44

than the group of the control hospitals

12:46

now was ten years younger. The researchers
