I used to say all the time, “Build muscle.”

But what I meant was, exercise

and eat protein.

So, that is actually wrong.

I do think you need to walk and so on,

but rather than the function of building,

what matters is not letting it break down.

And to keep it from breaking down,

it is important to suppress inflammation.

For that, dietary fiber is important.

Exactly.

When you improve that,

while we are exercising,

we think our body or muscles are being built,

everyone believes that, right?

We are going to publish a paper soon,

but when you exercise,

your gut bacteria change,

and only then can they act on the muscles.

So if you exercise…?

The effects of exercise

—everyone simply thinks that

if you exercise, you build muscle,

but it is not just that.

By exercising your whole body,

signals from those muscles act on the gut,

the gut bacteria change,

the metabolites change,

and in the end they reach the muscles.

Right now,

we already have a paper under review,

and it is extremely interesting.

It links exercise, gut bacteria, and muscle.

When it comes to gut bacteria,

it is a strange thing,

but gut bacteria

send us some kind of signal,

“Eat dietary fiber,”

a signal like that is sent,

and when your body becomes like that,

inevitably that person

no longer feels like eating meat

when they see it, and instead eats fiber,

or eats whole grains and so on.

They themselves say

they are making an effort to get fiber,

but in fact,

it might be that the ones inside the belly,

the fiber-loving

gut bacteria are

the ones that are controlling that person.

If that happens, that is a good death, isn’t it.

This has already been scientifically shown:

if you eat croquettes,

then when you see croquettes the next day,

you apparently want to eat them again.

It is like a drug in the brain,

a “croquette drug” is released.

It is the same thing:

because of foods that control the brain center,

people who eat meat every day,

it is not that they themselves are to blame.

I often tell Kazu-san this too:

“You are not the one at fault.”

You are just being deceived.

Please realize that soon.

People say that if you do things like this,

then in no time at all

you will become healthy.

They say that kind of thing a lot.

So in the end,

what you eat is really important, and

thinking about yourself

also means thinking about your gut bacteria.

If you think about your gut bacteria,

our gut bacteria

will pull us along

for the sake of our health.

Exactly.

That is amazing, so then

food that becomes feed for gut bacteria,

fermentable dietary fiber,

if we talk about it as “the dietary fiber from now on,”

we tend to get stuck just on things like lettuce,

because our minds get trapped there.

High-fermentation dietary fiber,

and then what we call “luminacoids” as well—

knowing that there are many different kinds of those,

keeping that in mind, and

once you know that and start eating that way,

you will be influenced so you want to eat it again,

and that creates a good cycle.

That leads to healthy longevity,

to a one-hundred-year life.
