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
