The Recipe for a Nourished Brain

Many of us have been told that foods like blueberries, salmon, and leafy greens are “good for the brain.” But what does that really mean? Can eating certain foods make us smarter? More alert? Less stressed? Sanjay talks to nutritional psychiatrist and personal chef, Dr. Uma Naidoo about what foods improve brain function and influence the way we feel. She’ll also share her secret sauce: a few nutritious and delicious ways to eat carbs, fats and sugar.

Angela Guo: So, it's the old adage
on what you eat

when I eaτ sugary or caffeinated food
I often find myself, like unable to focus

So, eating healthier food
has a significant impact on

how well I can focus, as well as
how quick I can focus.

Sanjay Gupta: That's Angela Guo.

She's a 17-year old senior at
Adlai Stevenson high school

in Lincolnshire, Illinois.

And that adage she just cited,
"You are what you eat",

that's been around since the 1800's.

People have known for a long time
just how much food affects us.

But it's not just in term of
long-term health,

but also short-term mood.

And sio eating healthier food has
a significant impact

AG Food really helps us maintain
a safe clarity

on how well I can focus, as well as
how quick I can think.

SG: She may only be in high school
but Angela has already made

the crucial connection between
what she puts in her mouth

and how quickly that affects her brain.

She even believes that
simple understanding

gave her a real advantage
when she competed

in the National Science Olympiad
tournament earlier this year.

Announcer: First place: National
champions of the 2023 Science xxxx

tournament: Adlai Stevenson
high school of Illinois, let's go!!

SG: Now at this tournament
earlier this year,

Angela and her team mates went up
against thousands of students

from around the country.

They were competing in events
highlighting chemistry, and neuroscience

and biology.

But here is the thing:
the entire time on Angela's team

you really didn't see much sugar around.

Instead,
there were lots of healthy snacks.

AG So, even at school, I bring
my own lunch

and it's just the asset of
knowing what goes into your meals

is like really important, it kind of
gives you peace of mind.

SG: The team did really well, and now
as they prepare for more tournaments,

Angela, who now is team captain, says,
sure, they study hard,

but what they eat, how they eat,
that's also top of mind.

AG: when we do travel for science contests
our cook always makes sure that

we are well stocked with fruit and water.

SG: So Angela seems pretty convinced
that food helps her focus

and perform well academically.

Of course, that makes sense
but the question today,

"What is the empirical evidence
to support that and how does it work?

How exactly does food impact the brain?

And how do we really know when our brain
is well nourished?"

Uma Naidoo: Sugar is not xxxx brain
