SPEAKER_01 (00:00):
Welcome to a deep dive dedicated to shortcuts for
being well-informed.
Today we're tackling a uh areally fascinating intersection
of diet, lifestyle, andneurology, the mindy diet.

SPEAKER_00 (00:12):
And this is one of those areas where specific,
sustained lifestyle choices seemto have these quantifiable,
robust associations withlong-term cognitive outcomes.
So powerful stuff.

SPEAKER_01 (00:23):
It really is.
So our mission today is simple.
We want to extract the criticalnuggets from the major studies.
What is this diet really?
How effective is it, you know,based on research from places
like Rush University and what'spublished in JMA?

SPEAKER_00 (00:36):
Aaron Powell And most importantly, the specific
steps you can actually take.

SPEAKER_01 (00:39):
Aaron Powell Exactly.
And the most encouraging part, Ithink, is that the research
shows massive benefit, even withjust moderate changes.

SPEAKER_00 (00:46):
Aaron Powell Right.
We're trying to cut through thenoise, all the general advice,
and focus only on the patternsthat researchers have seen
actively slow down cognitivedecline.

SPEAKER_01 (00:55):
Aaron Powell Okay, so let's unpack this.
What exactly is this diet?
I mean, they didn't just call itthe brain diet, they gave it
this very specific, almostacademic name.

SPEAKER_00 (01:02):
Aaron Powell The name really is the mission
statement.
The acronym MIND stands for theMediterranean Day SH
Intervention forNeurodegenerative Delay.

SPEAKER_01 (01:11):
Wow, okay.
That is a mouthful.
But the goal is crystal cleardelay.

SPEAKER_00 (01:17):
Precisely.
It was developed by Dr.
Martha Clare Morris and hercolleagues at Rush University
Medical Center.
And the key word is developed.
It's not just some randomcollection of healthy foods.

SPEAKER_01 (01:28):
So it was engineered in a way.

SPEAKER_00 (01:30):
It's a purposeful hybrid of two existing, very
successful diets.

SPEAKER_01 (01:33):
Yeah.

SPEAKER_00 (01:33):
The Mediterranean diet, which everyone knows, and
the DHH diet.
That stands for dietaryapproaches to stop hypertension.
Trevor Burrus, Jr.

SPEAKER_01 (01:40):
This is where it gets really interesting to me.
They didn't just say, hey, eat aMediterranean diet.
They specifically tailored thishybrid for the brain.
What was the thinking behindthat specific combination?

SPEAKER_00 (01:50):
Aaron Powell Well, the development was entirely
focused on leveraging the partsof both diets that are known to
impact brain function.
So the core idea is reallytwofold.

SPEAKER_01 (01:59):
Okay.

SPEAKER_00 (01:59):
First, to maximize your intake of antioxidative and
anti-inflammatory nutrients.
We know inflammation andoxidative stress are you know
key drivers ofneurodegeneration.

SPEAKER_01 (02:07):
Aaron Powell And the second part.

SPEAKER_00 (02:08):
Aaron Powell To aggressively reduce the harmful
stuff.
The bad fats, the processedfoods, basically anything that
harms the brain's vascular andmetabolic pathways.

SPEAKER_01 (02:19):
Aaron Powell That makes so much sense.
The blane is this incrediblydemanding organ, metabolically
speaking.
So optimizing the blood vesselsthat feed it, which is kind of
the DHH diet's whole thing, thathas to be critical.

SPEAKER_00 (02:30):
Aaron Powell It's a great analogy.
You're trying to optimize theentire fuel delivery and waste
cleanup system for the brain allat once.
And because this is anintervention, the specifics
really, really matter.
This isn't just eat healthy.

SPEAKER_01 (02:43):
Aaron Powell Let's get to those actionable details
then.
This is where you might want totake some notes.
What are the key things toemphasize?
What are the rules?

SPEAKER_00 (02:50):
We can break it down into the core staples.

SPEAKER_01 (02:52):
Okay.

SPEAKER_00 (02:52):
And let's start with what's I'd say non-negotiable.
Green leafy vegetables.
Okay.
You're aiming for at least oneserving every single day.
So spinach, kale, collards.
That's a daily pillar.

SPEAKER_01 (03:04):
Daily leafy greens.
Got it.
What's next?

SPEAKER_00 (03:06):
Aaron Powell Then you have berries.
And the minere research singlesout berries in a way it just
doesn't for other fruits.
Right.
Yes.
Two to five servings a week ofthings like blueberries,
strawberries, raspberries.
It's because of their specificflavonoid profiles, which are
uniquely linked to brainprotection.

SPEAKER_01 (03:24):
That is fascinating.
So if I'm eating, say, an appleor a banana every day, that
doesn't count towards thisspecific goal.

SPEAKER_00 (03:31):
It absolutely counts towards your overall health, of
course.
But the mind researchersisolated berries because they
contain compounds, anthocyanins,that seem to cross the
blood-brain barrier reallyeffectively.

SPEAKER_01 (03:42):
Okay, noted.
Focus the fruit budget onberries.
What about the bulk of the meal?
Grains, nuts, that sort ofthing.

SPEAKER_00 (03:49):
The structure relies on whole foods.
So you're aiming for three ormore servings of whole grains
daily, about five or moreservings of nuts and seeds per
milk, and then beans or legumes,maybe three to four times a
week.

SPEAKER_01 (04:01):
And protein and fats.
Those are always the big ones.

SPEAKER_00 (04:04):
Right.
The primary oil has to be extravirgin olive oil.
For protein, you want fatty fishlike salmon or sardines at least
once a week, and lean poultry,like chicken, two or more times
a week.

SPEAKER_01 (04:14):
Okay, so that's the eat this list.
Now for the hard part.
The constraints.
What are the absolute hardstops?

SPEAKER_00 (04:22):
This is where a lot of people struggle.
These limits are very specific,and they're targeted right at
saturated and trans fats.
First up, butter and margarine.
You have to limit them to lessthan one tablespoon per day.

SPEAKER_01 (04:35):
Wait, less than a tablespoon a day?
For everything?
That's that's incredibly strict.
Where did they pull thatspecific number from?

SPEAKER_00 (04:42):
That low threshold is really what differentiates
mine from a standardMediterranean diet, which is
usually way more flexible withfats.
The constraint is there tostrictly limit the type of
saturated fat that promotesinflammation and vascular
stiffness.

SPEAKER_01 (04:55):
So it's a hard limit for a reason.
Maximum protection, not justgeneral improvement.

SPEAKER_00 (04:59):
Exactly.
It's a targeted reduction.
The other big one is cheese.

SPEAKER_01 (05:02):
Oh no.

SPEAKER_00 (05:03):
Less than one serving per week, again,
targeting that saturated fatintake.
And beyond that, it's what you'dexpect limit red meat, processed
meats, pastries, sweets, andpretty much all fried or fast
food.

SPEAKER_01 (05:15):
Okay, that gives us a very clear, if challenging,
picture.
So let's look to the payoff.
The data.
The research linking all this toresults is what put it on the
map, right?

SPEAKER_00 (05:25):
Oh, absolutely.
What's so compelling is howconsistent the data is.
The early strongest data cameout of Rush University in 2015.
They analyzed older adults whodidn't have dementia at the
start.

SPEAKER_01 (05:37):
And what did they see?

SPEAKER_00 (05:38):
A really strong association with slower
cognitive decline and a,frankly, a dramatically lower
incidence of Alzheimer'sdisease.

SPEAKER_01 (05:46):
Aaron Powell And the specific stats here are what
everyone needs to hear.
This is the key takeaway.

SPEAKER_00 (05:50):
It is.
The research showed up to a 53%lower risk of Alzheimer's in the
people with the highestadherence to the diet.

SPEAKER_01 (05:57):
53%.
That's huge.

SPEAKER_00 (06:00):
But here's the crucial part, and I really want
to emphasize this.
Even those with just moderateadherence saw a huge benefit.
About a 35% lower risk.

SPEAKER_01 (06:09):
That 35% number.
That might be the most importantfinding in the whole thing.
It means you don't have to beperfect.
It makes it accessible.

SPEAKER_00 (06:16):
Exactly.
Yeah.
It validates the idea of makingsustainable incremental changes.
And this isn't a one-offfinding.
A 2023 meta-analysis in Jammapsychiatry confirmed it.
Higher adherence was associatedwith a lower risk of all-cause
dementia.
It just holds up.

SPEAKER_01 (06:32):
So a natural question is about timing.
Does this only work if you startwhen you're like 20?
Or can you still get a benefitif you start making changes in
midlife?

SPEAKER_00 (06:40):
Aaron Powell And that is where the newest
research is just so encouraging.
A very recent study looked at ahuge group, nearly 93,000 adults
aged 45 to 75.

SPEAKER_01 (06:50):
Okay.

SPEAKER_00 (06:51):
And they specifically looked at the
people who improve their minddiet score over a 10-year
period.

SPEAKER_01 (06:56):
Aaron Powell The improvers.
And what happened?

SPEAKER_00 (06:58):
They had about a 25% lower risk of dementia compared
to people whose diet qualitywent down.
It is powerful evidence that youcan get a clear, measurable
benefit even when you startmaking these changes later in
life.

SPEAKER_01 (07:09):
This all sounds, I mean, overwhelmingly positive.
But we have to ask the criticalquestions.
What are the limitations here?
The caveats?

SPEAKER_00 (07:16):
It's a really important question.
The main limitation is thatalmost all of this data is
observational.

SPEAKER_01 (07:21):
Meaning it shows a correlation, not necessarily a
direct cause and effect.

SPEAKER_00 (07:25):
Aaron Powell Precisely.
Observational studies alwayscarry that risk of confounding
factors.
Maybe people who stick to themind diet also exercise more or
they're more socially engaged,you know.
All those things also protectthe brain.

SPEAKER_01 (07:39):
So it's a very strong association and it makes
biological sense, but we can'tstamp proven cause on it just
yet.

SPEAKER_00 (07:45):
Exactly.
And we should also note thatsome of the longer-term
follow-up studies have shown aslightly weaker effect over
time.
So we need to be measured in ourenthusiasm.

SPEAKER_01 (07:55):
So bringing it all together, what does this mean
for you, the listener, trying tomanage your own risk?

SPEAKER_00 (07:59):
I think the implication is clear.
The mind diet is a very, verypromising lifestyle approach for
risk reduction.
But it's not a cure.
And it's not a magic bullet.

SPEAKER_01 (08:09):
It has to be part of a bigger picture.

SPEAKER_00 (08:11):
It absolutely must be integrated into a broader
brain health strategy.
Diet is one critical piece ofthe puzzle, but it has to be
combined with other provenfactors.

SPEAKER_01 (08:20):
Like what are those complementary strategies?

SPEAKER_00 (08:23):
Things like regular physical exercise, making sure
you get high-quality sleep,managing your vascular risk, so,
controlling blood pressure andsugar, and of course, staying
cognitively active.
The brain needs multiple linesof defense working together.

SPEAKER_01 (08:38):
This brings us perfectly to practical
application.
Let's make this realistic.
If just moving from low tomoderate adherence can give you
that 35% risk reduction, whatare the, say, four simplest,
highest impact changes someonecould make to get there?

SPEAKER_00 (08:54):
Okay.
The low-hanging fruit, numberone.
Start with the staples.
Just commit to one serving ofgreen leafy vegetables every
day.
It's achievable and it forces achange in how you build your
plate.
Number two, add thosebrain-specific berries.
Focus on getting those two tofive servings in per week.
And remember, frozen berries area fantastic cost-effective
option.
They're just as good.

(09:14):
Number three, a really simpleswap.
Make the oil swap.
Use extra virgin olive oil asyour primary oil for cooking and
dressings.
That's a foundational change foryour vascular health.

SPEAKER_01 (09:24):
And finally, let's hit those hard stops.
Reducing the harmful stuff oftengets you to that moderate level
the fastest.

SPEAKER_00 (09:31):
That's right.
So focus intensely on those twospecific limits we talked about.
Make cheese a once-a-week treat,not a daily thing, and really
slash your butter and margarineintake to less than that one
tablespoon a day.
Focusing there while adding thegreens and berries is the
fastest path to effective,moderate adherence.

SPEAKER_01 (09:51):
That's fantastic advice.
I think the key takeaway here isjust how consistent the message
is.
What we eat really truly mattersfor our brains, and these
specific, accessible dietarypatterns can offer significant
protection.

SPEAKER_00 (10:03):
And it raises an important final question,
doesn't it?
If we connect all this to thebigger picture of brain health,
it really makes you wonder howmuch of our cognitive destiny is
actually in our hands.
The fact that diet improvement,even later in life, yields this
measurable risk reduction.
It's just a powerful reminder ofour own agency.

SPEAKER_01 (10:20):
A deep thought to end on.
