  • Summary: Higher butter intake was linked to a 15% increased risk of total mortality; higher plant-based oil intake (olive, avocado, chia, walnut) was linked to a 16% reduced risk. Just two teaspoons a day of plant-based oil instead of butter was associated with a 17% lower risk of death.
  • Practical Tip: Swap in olive, avocado, or chia oil for sautéing or dressings a few times a week.

  • Summary: Just 23 (non-consecutive=OK!) minutes of brisk movement in daily life (cleaning, walking quickly while shopping, dancing, etc.) lowered risk of dying from all causes by up to 69%.
  • Practical Tip: Turn your daily chores or errands into intentional movement moments.

Transcripts

Speaker:

Sometimes the smallest shifts, a

Speaker:

different oil, a quicker step,

Speaker:

or a restorative fruit can

Speaker:

make real and positive impact

Speaker:

on our health, and we're

Speaker:

going to talk about it.

Speaker:

This is the kind of

Speaker:

science you can use that

Speaker:

actually fits into your day.

Speaker:

We experience 1,000 waking

Speaker:

minutes on average every day.

Speaker:

How are you spending yours?

Speaker:

I'm Dr. Wendy Bazilian, and

Speaker:

you're listening to 1,000 Waking

Speaker:

Minutes.

Speaker:

I can't wait to connect

Speaker:

with you here with practical

Speaker:

ways to eat well, move

Speaker:

daily, and be healthy, to

Speaker:

optimize every waking minute you

Speaker:

live for a happier, healthier

Speaker:

life.

Speaker:

Thank you for sharing some

Speaker:

of your waking minutes with

Speaker:

me today.

Speaker:

Let's get started.

Speaker:

I'm saying yes to better

Speaker:

days.

Speaker:

Yes, I'm on my way.

Speaker:

Yes, I'm on my way.

Speaker:

It's going to be okay,

Speaker:

yeah.

Speaker:

Good day, and welcome back

Speaker:

to 1,000 Waking Minutes.

Speaker:

I'm Dr. Wendy Bazilian, and

Speaker:

as always, I'm so glad

Speaker:

you're here with me today.

Speaker:

If you've listened before, you

Speaker:

know I love science, especially

Speaker:

good science.

Speaker:

And even when it challenges

Speaker:

what we thought we knew

Speaker:

or conflicts with something that

Speaker:

has been reported otherwise elsewhere

Speaker:

in the peer-reviewed research,

Speaker:

science does evolve.

Speaker:

Science helps make sense of

Speaker:

the world, and it helps

Speaker:

us test some hypotheses, real

Speaker:

scientific hypotheses, as well as

Speaker:

our own personal ideas, and

Speaker:

get some answers sometimes.

Speaker:

It can even help us

Speaker:

maybe establish some guidance, especially

Speaker:

in the complex area of

Speaker:

nutrition and fitness and health

Speaker:

and wellness.

Speaker:

And you know, science isn't

Speaker:

just about chasing the trends

Speaker:

or tossing out everything that

Speaker:

we thought we knew because

Speaker:

some new shiny headline breaks,

Speaker:

even though they are very

Speaker:

attention-grabbing at times.

Speaker:

But it's really about learning,

Speaker:

refining, paying attention to the

Speaker:

patterns and to the bigger

Speaker:

picture and the little details.

Speaker:

So it's big picture and

Speaker:

little details.

Speaker:

So we can live better

Speaker:

and not just longer when

Speaker:

it comes to our health.

Speaker:

So today's episode is one

Speaker:

of our science updates where

Speaker:

I bring you three studies

Speaker:

that caught my eyes, probably

Speaker:

yours, and the things that

Speaker:

sort of I wake up

Speaker:

and wonder about in the

Speaker:

night.

Speaker:

So a couple of them

Speaker:

are actually ones that you

Speaker:

all wrote me about, which

Speaker:

I'm super excited about.

Speaker:

And today we're going to

Speaker:

talk about them.

Speaker:

I'm going to break them

Speaker:

down and what they really

Speaker:

mean for our everyday choices.

Speaker:

So you're not here for

Speaker:

the clickbait, neither am I.

Speaker:

You're here for some clarity,

Speaker:

hopefully.

Speaker:

For some evidence it's actually

Speaker:

science we can use or

Speaker:

science to strategy, evidence we

Speaker:

can experience.

Speaker:

You know, I love alliteration

Speaker:

there.

Speaker:

So we'll talk about some

Speaker:

small swaps that may just

Speaker:

stretch your lifespan today and

Speaker:

improve the way that you

Speaker:

feel when you're in your

Speaker:

body.

Speaker:

We'll talk about the kind

Speaker:

of movement that protects your

Speaker:

heart without ever stepping foot

Speaker:

in the gym.

Speaker:

I'm not saying you shouldn't

Speaker:

or you might not be

Speaker:

doing that also, but it's

Speaker:

cool new research that's out

Speaker:

there.

Speaker:

And we'll also talk about

Speaker:

maybe a surprising food that

Speaker:

may help you fall asleep

Speaker:

faster, stay asleep longer, and

Speaker:

may help your overall well

Speaker:

-being.

Speaker:

Just practical shifts today and

Speaker:

some stories that back them

Speaker:

up with the science.

Speaker:

And as always, we'll close

Speaker:

with a quick recap so

Speaker:

that you can take away

Speaker:

with some actionable steps, something

Speaker:

concrete to try or share

Speaker:

this week, something that can

Speaker:

fit into your waking minutes.

Speaker:

So let's talk about the

Speaker:

science you can use.

Speaker:

First, we're going to begin

Speaker:

with eating well, the food

Speaker:

on your plate, and more

Speaker:

specifically what you're cooking your

Speaker:

food in or drizzling on

Speaker:

your food or using.

Speaker:

A new study from Harvard's

Speaker:

T.H. Chan School of

Speaker:

Public Health, the renowned team

Speaker:

and renowned university and research

Speaker:

institution that's done decades of

Speaker:

leading research in nutritional longevity,

Speaker:

they looked at how different

Speaker:

fats affect our long-term

Speaker:

health and risk of disease

Speaker:

from chronic diseases like cancer

Speaker:

and heart disease.

Speaker:

So here's the short version.

Speaker:

The type of fat you

Speaker:

eat matters, and in particular,

Speaker:

sort of the balance, not

Speaker:

that one's bad, but the

Speaker:

balance overall in your healthy

Speaker:

pattern of eating.

Speaker:

So it's not just how

Speaker:

much, it's the type and

Speaker:

the pattern.

Speaker:

So in this study, research

Speaker:

followed over 220,000 adults

Speaker:

over three large cohort studies.

Speaker:

You may have heard these

Speaker:

referenced before, the Nurses' Health

Speaker:

Study, the Nurses' Health Study

Speaker:

2 with Roman numeral 2

Speaker:

after it, and the Health

Speaker:

Professionals' Follow-Up Study.

Speaker:

This has been a study

Speaker:

that's been ongoing since 1990

Speaker:

-91.

Speaker:

And what they found is

Speaker:

that when looking at this

Speaker:

cohort, these three cohorts, that

Speaker:

those who consumed more plant

Speaker:

-based oils like olive oil,

Speaker:

avocado oil, even walnut oils

Speaker:

or chia oils, but plant

Speaker:

-based oils had significantly lower

Speaker:

risk of dying from all

Speaker:

causes, including heart disease and

Speaker:

cancer.

Speaker:

And they reported a 16

Speaker:

% lower total mortality risk.

Speaker:

That's significant.

Speaker:

Meanwhile, those who consumed more

Speaker:

butter, and I'm not coming

Speaker:

down on butter today, but

Speaker:

they had a higher risk

Speaker:

of total and cancer-related

Speaker:

mortality, in fact, a 15

Speaker:

% higher risk.

Speaker:

Those who consumed more butter

Speaker:

in the highest intake group,

Speaker:

they had a 15%

Speaker:

higher risk.

Speaker:

In other words, the risk

Speaker:

of dying from any cause

Speaker:

compared to those who ate

Speaker:

the least amount of butter.

Speaker:

Now, again, this doesn't mean

Speaker:

that butter is bad.

Speaker:

I like butter, and it's

Speaker:

not bad like the way

Speaker:

that we once thought, you

Speaker:

know, back in big bad

Speaker:

butter days, maybe the 1980s.

Speaker:

We've come a long way

Speaker:

from that fatphobic era and

Speaker:

that messaging, but it does

Speaker:

mean swapping in more plant

Speaker:

-based oils and that swapping

Speaker:

them in more and more

Speaker:

often can offer a science

Speaker:

-backed strategy, let's say.

Speaker:

And this isn't the first

Speaker:

study to report this.

Speaker:

This has been happening for

Speaker:

better over a decade, I

Speaker:

would say.

Speaker:

I think 2010, maybe, there

Speaker:

was a significant study or

Speaker:

2010, between 2010, 2015, a

Speaker:

significant study that really planted

Speaker:

this on the map, planted

Speaker:

plant oils, planted this on

Speaker:

the map as the importance

Speaker:

of swapping in polyunsaturated fats

Speaker:

for saturated fats.

Speaker:

This is an extension into

Speaker:

the plant oils, swapping some

Speaker:

in for butter.

Speaker:

So you don't have to

Speaker:

ban butter from your home,

Speaker:

but maybe we can be

Speaker:

a little bit more strategic.

Speaker:

Maybe saute your veggies in

Speaker:

olive oil more days than

Speaker:

not.

Speaker:

Try some other interesting plant

Speaker:

oils, high-quality ones, cold

Speaker:

-pressed oils, like in your

Speaker:

vinaigrettes, maybe a walnut oil,

Speaker:

or use chia oil, which

Speaker:

is cold-pressed, as I've

Speaker:

talked about before.

Speaker:

You can even put these

Speaker:

in smoothies or as a

Speaker:

baking swap or in blends

Speaker:

with our olive oil and

Speaker:

our avocado oil.

Speaker:

And so putting this into

Speaker:

everyday real life, this is

Speaker:

just as little as putting

Speaker:

in a teaspoon of oil

Speaker:

in one teaspoon increments, five

Speaker:

-gram increments, that made significant

Speaker:

differences.

Speaker:

One teaspoon of cold-pressed

Speaker:

organic canola oil, 15%

Speaker:

lower risk of death.

Speaker:

One teaspoon of olive oil

Speaker:

per day, 8% lower

Speaker:

risk.

Speaker:

One teaspoon of, again, high

Speaker:

-quality soybean oil, 6%

Speaker:

lower risk.

Speaker:

And we're not talking about

Speaker:

seed oils today.

Speaker:

I am talking about high

Speaker:

-quality oils and the importance

Speaker:

of plant-based oils, according

Speaker:

to this research.

Speaker:

And when it came to

Speaker:

evaluating cancer and heart health,

Speaker:

every two teaspoons or 10

Speaker:

grams of more plant oil

Speaker:

per day was linked to

Speaker:

11% lower risk of

Speaker:

dying from cancer and a

Speaker:

6% lower risk of

Speaker:

dying from heart disease.

Speaker:

So this really starts to

Speaker:

underscore the importance of some

Speaker:

simple swaps, like replacing two

Speaker:

teaspoons of butter a day

Speaker:

with two teaspoons of plant

Speaker:

-based oil.

Speaker:

That's a tongue twister if

Speaker:

I ever had one.

Speaker:

But replacing two teaspoons with

Speaker:

two teaspoons of the plant

Speaker:

-based oil led to a

Speaker:

reported 17% lower risk

Speaker:

of death and 17%

Speaker:

lower risk of dying from

Speaker:

cancer.

Speaker:

So I think it's important

Speaker:

for us to remember plant

Speaker:

oils also come with other

Speaker:

things that plants have, especially

Speaker:

when they're cold-pressed and

Speaker:

they're not ultra-refined with

Speaker:

solvents and enzymes.

Speaker:

They still have remaining plant

Speaker:

nutrients as well.

Speaker:

So plant oils do come

Speaker:

with things like polyphenols, antioxidants,

Speaker:

even omega-3s, as in

Speaker:

the case with chia oil

Speaker:

or high-quality flax oil

Speaker:

or walnut oil.

Speaker:

So it's not just a

Speaker:

fat gram or a fat

Speaker:

calorie, and it's not just

Speaker:

a trade for that.

Speaker:

It's part of the broader

Speaker:

shift toward that plant-based

Speaker:

equals more nutrients and more

Speaker:

nutrient-rich choices.

Speaker:

So this ultimately means small

Speaker:

daily swaps, like sauteing, that

Speaker:

they can make a meaningful

Speaker:

difference over time.

Speaker:

And it's not about eliminating

Speaker:

butter, but shifting the balance

Speaker:

or evaluating what you're already

Speaker:

doing well, maybe.

Speaker:

Maybe this just is a

Speaker:

study that underscores that you're

Speaker:

doing great things to help

Speaker:

manage your disease risk, to

Speaker:

maximize and optimize your healthy,

Speaker:

vital living with your waking

Speaker:

minutes and your choices.

Speaker:

So you've got those

Speaker:

1,000 waking minutes in your

Speaker:

day, so why not let

Speaker:

some of those be thoughtful

Speaker:

around the types of fats

Speaker:

you choose to use?

Speaker:

Your day can be filled

Speaker:

with lots of little decisions

Speaker:

toward this end.

Speaker:

And again, I love my

Speaker:

butter.

Speaker:

There are certain things that

Speaker:

there's non-negotiable where butter

Speaker:

will win, but you might

Speaker:

think about a trade on

Speaker:

some instances.

Speaker:

All right, so moving from

Speaker:

what's in your pan or

Speaker:

maybe what's in your vinaigrette

Speaker:

to how you move your

Speaker:

body.

Speaker:

So we're going to move

Speaker:

daily.

Speaker:

Remember, eat well, move daily,

Speaker:

be healthy.

Speaker:

I'm going to have a

Speaker:

little bit of each of

Speaker:

those today.

Speaker:

So this is about how

Speaker:

you move your body throughout

Speaker:

the day.

Speaker:

And if the words like

Speaker:

a formal workout routine or

Speaker:

the days you must go

Speaker:

to the gym, if those

Speaker:

things make you roll your

Speaker:

eyes back or just glaze

Speaker:

over, you're probably half-tuned

Speaker:

out already.

Speaker:

I've got a good study

Speaker:

to share with you today.

Speaker:

New studies published in Circulation,

Speaker:

that's the journal of the

Speaker:

American Heart Association, peer-reviewed

Speaker:

journal, real high-quality journal.

Speaker:

It looked at IPA, not

Speaker:

IPA the beer, but IPA,

Speaker:

incidental physical activity.

Speaker:

And by incidental, I mean

Speaker:

the stuff you're probably already

Speaker:

doing or could easily do

Speaker:

without joining a gym or

Speaker:

buying any gear or going

Speaker:

to a platform class like

Speaker:

I did last week as

Speaker:

part of a group from

Speaker:

my daughter's school.

Speaker:

We're talking actually about IPA,

Speaker:

so that incidental physical activity

Speaker:

like brisk walking while you're

Speaker:

running errands, like carrying your

Speaker:

groceries, like cleaning, cleaning, vacuuming

Speaker:

or cleaning with a little

Speaker:

extra oomph, you know, like

Speaker:

putting a little more into

Speaker:

it.

Speaker:

The type that breaks a

Speaker:

sweat even when you're hustling

Speaker:

around the house for guests

Speaker:

to come.

Speaker:

Think about that because it

Speaker:

really counts and it pays

Speaker:

off.

Speaker:

And maybe that can put

Speaker:

actually a new spin on

Speaker:

tidying up and cleaning in

Speaker:

this manner.

Speaker:

So in this study, researchers

Speaker:

tracked over 6,000 adults

Speaker:

ages 40 to 69, and

Speaker:

they were wearing on their

Speaker:

wrists accelerometers.

Speaker:

So that sort of measures

Speaker:

the calorie and energy expenditure

Speaker:

from movement.

Speaker:

They're kind of like the

Speaker:

Fitbits.

Speaker:

Some of you may even

Speaker:

have them.

Speaker:

And they can get at

Speaker:

more real world, like minute

Speaker:

to minute data.

Speaker:

And what they found was

Speaker:

really compelling.

Speaker:

Those who simply did their

Speaker:

tasks, their daily tasks at

Speaker:

a brisker pace, like with

Speaker:

more intention and purpose, like

Speaker:

vacuuming like you mean it

Speaker:

or powering through the grocery

Speaker:

store with your list on

Speaker:

a mission, they saw up

Speaker:

to a 67% reduction

Speaker:

in cardiac and cardiovascular diseases.

Speaker:

And they saw a 69%

Speaker:

lower chance of dying

Speaker:

from any causes.

Speaker:

That's called overall mortality in

Speaker:

science talk.

Speaker:

A 69% lower chance.

Speaker:

So in other words, people

Speaker:

who moved more intensely during

Speaker:

their everyday tasks were significantly

Speaker:

less likely to die from

Speaker:

things like heart disease, cancer,

Speaker:

or other major health issues

Speaker:

compared to those who were

Speaker:

least active or least doing

Speaker:

this.

Speaker:

So this is pretty remarkable.

Speaker:

This is research that is

Speaker:

compelling and, you know, sort

Speaker:

of maybe makes sense, but

Speaker:

it's nice to have numbers

Speaker:

and significance to show that

Speaker:

what you do and with

Speaker:

what intensity counts, and it's

Speaker:

cumulative.

Speaker:

So I want to be

Speaker:

more clear about this.

Speaker:

This wasn't the hours in

Speaker:

the gym.

Speaker:

These were short, moderate intensity

Speaker:

movements woven into daily life.

Speaker:

The benefits started around 23

Speaker:

minutes in a day of

Speaker:

brisk activity, and it wasn't

Speaker:

23 minutes in tandem.

Speaker:

It wasn't 23 minutes consecutively.

Speaker:

It was 23 minutes total

Speaker:

of more intensely moving and

Speaker:

doing more IPA, more of

Speaker:

that movement during your everyday

Speaker:

activities.

Speaker:

So I want to like

Speaker:

sort of hit pause on

Speaker:

the episode for a second

Speaker:

on that thought to also

Speaker:

say, of course, that it

Speaker:

doesn't mean that we don't

Speaker:

need structured exercise or that

Speaker:

the morning walk or your

Speaker:

strength classes, that those aren't

Speaker:

worthwhile.

Speaker:

In fact, they are worthwhile

Speaker:

for a multitude of reasons,

Speaker:

which I speak to on

Speaker:

a regular basis, and they

Speaker:

have great benefits in their

Speaker:

own right.

Speaker:

But it does mean that

Speaker:

the formal workout isn't essential

Speaker:

all the time, or if

Speaker:

it's not accessible to you,

Speaker:

that there's no point or

Speaker:

you're not getting any value

Speaker:

about what you do and

Speaker:

how you move.

Speaker:

Because if time, cost, child

Speaker:

care, injuries, or if you're

Speaker:

just feeling burned out, there's

Speaker:

another way in to credit

Speaker:

for what you're doing that

Speaker:

has a real health impact.

Speaker:

So this study really reinforces

Speaker:

what I always say, move

Speaker:

daily.

Speaker:

It doesn't have to mean

Speaker:

work out.

Speaker:

It can be something that's

Speaker:

just moving more, moving daily.

Speaker:

And it might unload some

Speaker:

of the burden that you

Speaker:

place on your mind.

Speaker:

And it might be done

Speaker:

by unloading something else, like

Speaker:

your grocery bags from your

Speaker:

car in one more trip

Speaker:

than trying to get it

Speaker:

all on your arms.

Speaker:

I've been known to do

Speaker:

that at one trip.

Speaker:

It might justify that instead

Speaker:

of carrying it all at

Speaker:

once or doing yard work

Speaker:

and walking briskly while you're

Speaker:

doing it and working hard

Speaker:

and knowing that it counts.

Speaker:

It might be justification for

Speaker:

actually parking further instead of

Speaker:

scrambling and maybe becoming frustrated

Speaker:

that you can't find a

Speaker:

spot up close because you're

Speaker:

tag teaming with something else

Speaker:

that has real impact on

Speaker:

your health.

Speaker:

And it could even be

Speaker:

that sort of cranking up

Speaker:

the music while you're getting

Speaker:

dinner ready.

Speaker:

You can do it on

Speaker:

your own.

Speaker:

You can invite someone in

Speaker:

like a child.

Speaker:

You can even dance around

Speaker:

with your pet if you

Speaker:

dare or if you care.

Speaker:

And if you want to,

Speaker:

which I think is fun.

Speaker:

So the key here is

Speaker:

really intention.

Speaker:

It's giving a little more

Speaker:

energy, a little more purpose

Speaker:

to your movement that you're

Speaker:

already doing.

Speaker:

And if you're doing this

Speaker:

while you're folding your laundry,

Speaker:

well, fold it, you know,

Speaker:

maybe march in place or

Speaker:

toss in a few squats

Speaker:

when you're doing that.

Speaker:

When you head out to

Speaker:

run errands today, purposefully park

Speaker:

a little further.

Speaker:

Or could you even walk?

Speaker:

Are there stairs that you

Speaker:

might be able to take

Speaker:

instead of the elevator?

Speaker:

Those are the kinds of

Speaker:

things you've heard before, but

Speaker:

they're not gimmicks.

Speaker:

They're really important and they're

Speaker:

grounded in evidence.

Speaker:

And they're about reclaiming the

Speaker:

idea that movement belongs anywhere

Speaker:

and movement belongs to everyone,

Speaker:

not just when you're dressed

Speaker:

in the proper yoga wear

Speaker:

or athleisure, I think they

Speaker:

call it, or on a

Speaker:

peloton or at the specialty

Speaker:

exercise class.

Speaker:

So let's all, you know,

Speaker:

sort of make a commitment

Speaker:

together that to make our

Speaker:

daily minutes, the errands, the

Speaker:

chores, our dog walks, or

Speaker:

just, you know, carrying around

Speaker:

boxes and putting things away,

Speaker:

make those movements with purpose.

Speaker:

OK, so let's now shift

Speaker:

into a different kind of

Speaker:

energy, something that lives right

Speaker:

on the edge of our

Speaker:

1,000 waking minutes.

Speaker:

And this is sort of

Speaker:

in the be healthy space.

Speaker:

This is something that actually

Speaker:

powers our waking minutes.

Speaker:

And if you think about

Speaker:

zooming out for a moment

Speaker:

and knowing that this podcast

Speaker:

is about our waking minutes,

Speaker:

the hours that we live

Speaker:

with intention, we're awake.

Speaker:

We know that about 440

Speaker:

of those, somewhere between 420

Speaker:

and 480 daily minutes are

Speaker:

meant to be spent asleep

Speaker:

for good health, to support

Speaker:

our health in a foundational

Speaker:

way for long term health,

Speaker:

for emotional balance, for mental

Speaker:

clarity, immune resilience, even for

Speaker:

creativity.

Speaker:

Now, why did I just

Speaker:

say 420 to 480 minutes?

Speaker:

Well, of course, because that's

Speaker:

between that sort of magical

Speaker:

7 to 8 hours that

Speaker:

many research papers have suggested

Speaker:

for most of us can

Speaker:

really help us get restorative

Speaker:

sleep that's health promoting and

Speaker:

health supporting.

Speaker:

So what we do when

Speaker:

we're awake totally matters.

Speaker:

And that's what this podcast

Speaker:

is about, how we use

Speaker:

our waking minutes, how we

Speaker:

choose to use them, how

Speaker:

we slice and dice them

Speaker:

and how their life's currency

Speaker:

that are ours to operate

Speaker:

around and to value toward

Speaker:

a well-lived life.

Speaker:

But also remembering that it's

Speaker:

sleep that can help power

Speaker:

those waking minutes, how we

Speaker:

rest is just as vital.

Speaker:

And that brings me into

Speaker:

our third study for today,

Speaker:

or actually rather a small

Speaker:

collection of studies.

Speaker:

And it's all about kiwis,

Speaker:

the fruit, the fuzzy green

Speaker:

fruit.

Speaker:

So you might wonder why

Speaker:

bring up a kiwi now.

Speaker:

And the original study that

Speaker:

I'm going to reference was

Speaker:

actually published quite a while

Speaker:

ago.

Speaker:

So it's not late breaking,

Speaker:

last minute, right now news.

Speaker:

It was published in 2001 [mispoke...actually: 2011!]

Speaker:

in the Asia-Pacific Journal

Speaker:

of Clinical Nutrition.

Speaker:

So it's not exactly hot

Speaker:

off the press, but what's

Speaker:

happening right now is a

Speaker:

surge of renewed interest, which

Speaker:

is why I want to

Speaker:

bring it up.

Speaker:

It's kind of a research

Speaker:

revival of sorts.

Speaker:

A few people have asked

Speaker:

me about kiwi for sleep

Speaker:

after seeing a headline or

Speaker:

social post recently.

Speaker:

And one person in particular -

Speaker:

thank you, Sara! - is one

Speaker:

of those, a personal friend.

Speaker:

And another friend and fellow

Speaker:

dietitian also wrote a piece

Speaker:

for Very Well Health recently

Speaker:

just in the last month

Speaker:

about kiwi and health and

Speaker:

referenced around some of this

Speaker:

information.

Speaker:

And so I saw it

Speaker:

referenced again then in another

Speaker:

publication talking about elite athletes

Speaker:

using kiwi as part of

Speaker:

their recovery routine.

Speaker:

And this was from a

Speaker:

study a few years ago

Speaker:

that actually I had shared

Speaker:

in a presentation about sports

Speaker:

nutrition and recovery around the

Speaker:

same time it first came

Speaker:

out.

Speaker:

This kind of spurred an

Speaker:

organic curiosity, and it usually

Speaker:

tells me like something's bubbling

Speaker:

up.

Speaker:

Is there a hot new

Speaker:

study?

Speaker:

And why are we looking

Speaker:

at this?

Speaker:

And I decided to take

Speaker:

a closer look.

Speaker:

So I dug in a

Speaker:

bit and sort of followed

Speaker:

my nose, not like a

Speaker:

bloodhound per se, but sort

Speaker:

of like a scientist detective.

Speaker:

And I'm just realizing that

Speaker:

my daughter, who has said

Speaker:

she was going to be

Speaker:

an animal doctor, since you

Speaker:

could say the word dog

Speaker:

and doctor, veterinarian, of course,

Speaker:

she also puts a hyphen

Speaker:

sometimes on her career future.

Speaker:

She calls herself a veterinarian

Speaker:

detective.

Speaker:

So I decided maybe that's

Speaker:

where it comes from.

Speaker:

I'm a science detective at

Speaker:

times.

Speaker:

And here's what I found

Speaker:

when I dug around a

Speaker:

little and why I think

Speaker:

it's timely and relevant right

Speaker:

now to talk about kiwi

Speaker:

fruit and sleep.

Speaker:

So in the original clinical

Speaker:

trial in 2011, when it

Speaker:

was published, researchers had adults

Speaker:

with self-reported sleep problems

Speaker:

eat two green kiwis one

Speaker:

hour before bed for four

Speaker:

weeks.

Speaker:

So they took no other

Speaker:

pills, no melatonin, just the

Speaker:

fruit before bed.

Speaker:

And the results were quite

Speaker:

impressive.

Speaker:

One small study, but the

Speaker:

participants fell asleep 35 percent

Speaker:

faster.

Speaker:

They slept 13 percent longer

Speaker:

and they had fewer nighttime

Speaker:

awakenings, along with improved sleep

Speaker:

reports.

Speaker:

So their sleep efficiency, it's

Speaker:

called, improved.

Speaker:

And this is significant.

Speaker:

And by the way, it's

Speaker:

also safe and simple and

Speaker:

affordable.

Speaker:

But we, the big we,

Speaker:

the headlines didn't hear a

Speaker:

lot about it back then.

Speaker:

You know, the idea of

Speaker:

sleep and health was sort

Speaker:

of burgeoning and bubbling, but

Speaker:

it was important in the

Speaker:

growing sleep nutrition research.

Speaker:

So, you know, I've mentioned

Speaker:

it many times.

Speaker:

I would.

Speaker:

I still do when I

Speaker:

talk about sleep and foods

Speaker:

that might help or about

Speaker:

different foods with nutrients and

Speaker:

phytochemicals that have impact on

Speaker:

various aspects on our health,

Speaker:

like gut health and sleep

Speaker:

and energy and skin health,

Speaker:

naming a few that kiwi

Speaker:

may be involved in through

Speaker:

their nutrients.

Speaker:

Not all research has been

Speaker:

on kiwi and those health

Speaker:

outcomes, but the nutrients in

Speaker:

them.

Speaker:

But this was not hot

Speaker:

off the presses at the

Speaker:

moment, as I mentioned.

Speaker:

But the idea of sleeping,

Speaker:

getting to sleep faster, sleeping

Speaker:

longer and sleeping better.

Speaker:

Yes, and please and thank

Speaker:

you to all of those.

Speaker:

There was another study in

Speaker:

2023.

Speaker:

So I mentioned an athlete

Speaker:

study.

Speaker:

So a couple of years

Speaker:

ago, not long ago, a

Speaker:

newer study looking at elite

Speaker:

athletes with a similar routine.

Speaker:

They were elite runners, national

Speaker:

level sailors, like sailing boats

Speaker:

who ate two kiwis before

Speaker:

bed for four weeks.

Speaker:

And even in this highly

Speaker:

trained group, the results echoed

Speaker:

the 2011 study.

Speaker:

Total sleep time increased by

Speaker:

an hour.

Speaker:

That's significant.

Speaker:

Sleep efficiency improved over 93

Speaker:

percent.

Speaker:

Nighttime awakenings dropped and the

Speaker:

athletes even reported better mood

Speaker:

and alertness and less fatigue.

Speaker:

So no supplements again, just

Speaker:

kiwi.

Speaker:

They're rich, by the way,

Speaker:

in serotonin, which is a

Speaker:

melatonin precursor.

Speaker:

They have vitamin C at

Speaker:

very high levels.

Speaker:

Your full daily recommendation, just

Speaker:

one kiwi.

Speaker:

They have folate.

Speaker:

They have antioxidants.

Speaker:

They have potassium, all of

Speaker:

which we know are nutrients

Speaker:

that can help play a

Speaker:

role in sleep regulation and

Speaker:

recovery.

Speaker:

And there's another study around

Speaker:

that same time that the

Speaker:

athlete study came out, published,

Speaker:

I think the end of

Speaker:

2023.

Speaker:

That evaluated the effects of

Speaker:

kiwi and vitamin C supplements.

Speaker:

So it's kiwi versus vitamin

Speaker:

C supplements.

Speaker:

I mentioned that kiwis are

Speaker:

very high in vitamin C

Speaker:

and it was a particular

Speaker:

type of kiwi that's even

Speaker:

higher in vitamin C in

Speaker:

individuals who had low vitamin

Speaker:

C levels.

Speaker:

And they measured the impact

Speaker:

on well-being.

Speaker:

And I think maybe it

Speaker:

was mood.

Speaker:

I'm a little rusty on

Speaker:

this study, but it came

Speaker:

to mind as I was

Speaker:

looking at it.

Speaker:

I didn't dig into that

Speaker:

one because I really wanted

Speaker:

to focus on sleep, but

Speaker:

I do recall one on

Speaker:

well-being overall, which re

Speaker:

-upped it recently for its

Speaker:

rediscovery in the media headlines.

Speaker:

So anyway, why now?

Speaker:

This is the long way

Speaker:

to say, why is there

Speaker:

renewed interest in this?

Speaker:

Aside from who doesn't want

Speaker:

to find another reason to

Speaker:

love kiwis, which I do,

Speaker:

recognizing that some people are

Speaker:

allergic, which I'm sad about,

Speaker:

but I understand that.

Speaker:

But I think that now

Speaker:

it's because sleep is not

Speaker:

just a side issue anymore.

Speaker:

Well-being is at the

Speaker:

forefront of our minds.

Speaker:

And these are super key.

Speaker:

They're foundational to our health,

Speaker:

our be healthy pillar.

Speaker:

It's right there.

Speaker:

Eat well, move daily, be

Speaker:

healthy.

Speaker:

And it's an intersection of

Speaker:

two of those, eating well

Speaker:

through kiwi and better sleep.

Speaker:

I mean, seriously, sign me

Speaker:

up for that one because

Speaker:

it's a great bridge between

Speaker:

the two.

Speaker:

And sleep is one of

Speaker:

our top public health concerns

Speaker:

that we say subjectively, like

Speaker:

poor sleep.

Speaker:

And we know in the

Speaker:

science that it can negatively

Speaker:

impact our health.

Speaker:

It can even impact our

Speaker:

workplace performance.

Speaker:

And so increasingly, employers and

Speaker:

institutions and companies, and even

Speaker:

if you're self-employed, you

Speaker:

recognize that your performance can

Speaker:

be impacted by poor sleep.

Speaker:

We're tired.

Speaker:

We're overstimulated.

Speaker:

And we're looking for something

Speaker:

that's not a pill, but

Speaker:

still effective.

Speaker:

I think that some of

Speaker:

that is why we're hearing

Speaker:

again about this cool research.

Speaker:

And I actually hope that

Speaker:

some researchers will repeat and

Speaker:

replicate and show us more

Speaker:

about the impact of kiwi

Speaker:

on sleep, on energy, on

Speaker:

well-being.

Speaker:

And by the way, it's

Speaker:

something that you could try

Speaker:

tonight without side effects or

Speaker:

complicated routine.

Speaker:

It's a humble, naturally nutrient

Speaker:

-rich food that I hope

Speaker:

that you get into your

Speaker:

fruit basket anyway.

Speaker:

But this is one of

Speaker:

the reasons why I'm bringing

Speaker:

these little bit older studies

Speaker:

back into the spotlight and

Speaker:

why probably some of my

Speaker:

peers and some of the

Speaker:

respected journalists I've seen are

Speaker:

looking at these right now,

Speaker:

even though they're not brand

Speaker:

new, because they're newly relevant

Speaker:

and they're worth considering now.

Speaker:

So I talked a little

Speaker:

bit about the nutrient 'why',

Speaker:

the serotonin, the vitamin C,

Speaker:

the folate, you know, different

Speaker:

key nutrients, fiber.

Speaker:

There's been some research on

Speaker:

the gut health and the

Speaker:

gut microbiome and kiwi and

Speaker:

certainly the nutrients in kiwi

Speaker:

and gut health.

Speaker:

And there's really no downside

Speaker:

to you experimenting with this.

Speaker:

So kiwis are a fruit.

Speaker:

They're fiber.

Speaker:

They're flavor.

Speaker:

And if the side effect

Speaker:

is better sleep, that's a

Speaker:

pretty big win in my

Speaker:

book.

Speaker:

So beyond the numbers, this

Speaker:

is a moment for us

Speaker:

to pause and think bigger.

Speaker:

Because if we have roughly

Speaker:

1,000 waking minutes each

Speaker:

day to be engaged and

Speaker:

active and creative and thoughtful,

Speaker:

then getting restorative sleep isn't

Speaker:

just a nighttime goal.

Speaker:

It's a daytime strategy.

Speaker:

So that's how I want

Speaker:

and why I'll come back

Speaker:

to sleep very often in

Speaker:

a podcast called '1,000

Speaker:

Waking Minutes'.

Speaker:

So if you're looking for

Speaker:

a nudge toward more restorative

Speaker:

sleep and better waking minutes,

Speaker:

in other words, to support

Speaker:

your nights and also your

Speaker:

days, consider this your invitation

Speaker:

to two kiwis approximately an

Speaker:

hour before bed, maybe as

Speaker:

the dessert instead of a

Speaker:

more sugary dessert, which may

Speaker:

negatively impact your sleep.

Speaker:

Maybe put it with a

Speaker:

herbal tea or a ritual.

Speaker:

Maybe not with your phone

Speaker:

in hand.

Speaker:

Maybe you take out something

Speaker:

else like a real live

Speaker:

magazine or engage in a

Speaker:

conversation with a loved one.

Speaker:

And then just see.

Speaker:

Notice how your body feels

Speaker:

on this.

Speaker:

Notice your energy, your focus,

Speaker:

your mood.

Speaker:

Maybe you do need to

Speaker:

try it out for a

Speaker:

number of weeks.

Speaker:

You know, be a scientist.

Speaker:

Be a scientist detective and

Speaker:

make discoveries about your own

Speaker:

body because sleep, I think,

Speaker:

is like a silent superpower.

Speaker:

We don't always get what

Speaker:

we need.

Speaker:

I'm a working mom.

Speaker:

I'm short on sleep.

Speaker:

Sometimes I do a lot

Speaker:

of a lot of hours

Speaker:

like you probably do as

Speaker:

well.

Speaker:

I wake sometimes anxiously.

Speaker:

I'm a big thinker, but

Speaker:

I'm always pursuing because I

Speaker:

know that sleep is a

Speaker:

superpower and it really helps

Speaker:

us do better and accomplish

Speaker:

more.

Speaker:

And it has a major

Speaker:

impact on our health.

Speaker:

It makes our waking minutes

Speaker:

better, makes them clearer and

Speaker:

sharper, kinder, more patient, and

Speaker:

it makes us more resilient

Speaker:

in our physical self and

Speaker:

our long-term health.

Speaker:

So it can put us

Speaker:

back on the map for

Speaker:

the day to be more

Speaker:

alert and have more presence

Speaker:

in your day.

Speaker:

And being rested isn't a

Speaker:

luxury.

Speaker:

We shouldn't think of it

Speaker:

that way.

Speaker:

It's foundational to your health.

Speaker:

And this is not bad

Speaker:

for a fruit and an

Speaker:

old study that's been resurfacing,

Speaker:

and it's not too hard

Speaker:

to toss them into your

Speaker:

grocery cart.

Speaker:

And maybe this is the

Speaker:

first time, at least along

Speaker:

this podcast journey that I'm

Speaker:

on, that I can say,

Speaker:

take two, call me in

Speaker:

the morning, and hopefully it'll

Speaker:

be a well-slept and

Speaker:

energized morning at that.

Speaker:

So there you have it.

Speaker:

Three pieces of science that

Speaker:

stood out, not just because

Speaker:

they were well-designed or

Speaker:

well-reported, but because they

Speaker:

matter, because they translate.

Speaker:

And this is not to

Speaker:

generalize what the study findings

Speaker:

were to us in a

Speaker:

direct way, because that's not

Speaker:

responsible science, but to take

Speaker:

what the science showed and

Speaker:

see if there's translational moments

Speaker:

or things that we can

Speaker:

try in our own life

Speaker:

and see for ourselves.

Speaker:

Because sometimes science can meet

Speaker:

us right in the kitchen,

Speaker:

or it can meet us

Speaker:

while we're doing our chores,

Speaker:

and it can meet us

Speaker:

in our final moments before

Speaker:

bed.

Speaker:

So as a recap, we

Speaker:

talked about the power of

Speaker:

simple and the importance of

Speaker:

simple fats in our diet,

Speaker:

the importance of them, and

Speaker:

choosing to swap more olive

Speaker:

oil, more avocado oil, more

Speaker:

chia oil, high-quality oils,

Speaker:

over butter where it makes

Speaker:

a difference in your life.

Speaker:

Sometimes, not all the time.

Speaker:

Again, not because butter's a

Speaker:

villain, but because more plant

Speaker:

-based fats have some little

Speaker:

extra goodness, some more nutrients,

Speaker:

and can support long-term

Speaker:

health.

Speaker:

Then we moved into how

Speaker:

working into moving on purpose,

Speaker:

doing errands, cleaning the house,

Speaker:

walking through a store on

Speaker:

a mission, that can be

Speaker:

good.

Speaker:

And maybe that's just a

Speaker:

reframe in your mind that

Speaker:

what you're doing matters toward

Speaker:

your health, and it can

Speaker:

significantly reduce your risk of

Speaker:

heart disease and even lower

Speaker:

overall mortality, according to the

Speaker:

research.

Speaker:

So worth giving a try

Speaker:

and to weave it into

Speaker:

your life.

Speaker:

And finally, we zoomed back

Speaker:

out on this small fruit

Speaker:

and looked at a few

Speaker:

studies and why the renewal

Speaker:

and the resurgence, and looked

Speaker:

at the studies, a few

Speaker:

that showed two kiwi an

Speaker:

hour before bed helped people

Speaker:

in these studies fall asleep

Speaker:

faster, sleep longer, wake up

Speaker:

less often.

Speaker:

And when you think about

Speaker:

it, better sleep means better

Speaker:

days.

Speaker:

And that's what 1,000

Speaker:

waking minutes is really about.

Speaker:

So three quick things you

Speaker:

can do this week.

Speaker:

Swap your cooking fat.

Speaker:

Try some avocado oil, some

Speaker:

olive oil, some chia oil,

Speaker:

walnut oil instead of butter

Speaker:

a couple times.

Speaker:

Move with more intention.

Speaker:

So pick up the pace

Speaker:

while you're doing what you're

Speaker:

already doing and know that

Speaker:

it adds up.

Speaker:

And put kiwis on your

Speaker:

grocery list.

Speaker:

Eat two an hour before

Speaker:

bed.

Speaker:

See if it helps your

Speaker:

sleep.

Speaker:

Probably not a one-time

Speaker:

thing.

Speaker:

Who knows?

Speaker:

Maybe there's both combination of

Speaker:

reality and placebo effect at

Speaker:

one time.

Speaker:

But this would be a

Speaker:

consistent move that you can

Speaker:

try.

Speaker:

So put them on your

Speaker:

grocery list.

Speaker:

And remember, it's not about

Speaker:

doing everything or doing it

Speaker:

all perfectly.

Speaker:

It's about the small meaningful

Speaker:

actions that add up.

Speaker:

And you don't need to

Speaker:

completely overhaul your life.

Speaker:

Hopefully you're getting that message

Speaker:

loud and clear.

Speaker:

Just one thoughtful choice and

Speaker:

knowing that you have

Speaker:

1,000 waking minutes, your life's

Speaker:

currency, deposited each day upon

Speaker:

waking.

Speaker:

So if this episode gave

Speaker:

Speaker:

I'd love to hear from

Speaker:

you.

Speaker:

I'd love you to share

Speaker:

it with a friend.

that you might be confused

Speaker:

about, you know, scratching your

Speaker:

head, you know, send it

Speaker:

to me.

Speaker:

And I just might feature

Speaker:

it in a future episode

Speaker:

or we can interact and

Speaker:

converse.

Speaker:
