Speaker 1 (00:00):
Let's switch gears. But we're going to keep it medical.
We're gonna keep it medical. Here.

Speaker 2 (00:03):
I'm so pleased to welcome back to the show.

Speaker 1 (00:06):
It's been way too long since I've had a chance
to talk to.

Speaker 2 (00:09):
Doctor Marty McCarey.

Speaker 1 (00:10):
Marty is a professor of medicine and the chief of
islet transplant surgery at Johns Hopkins. And Marty became kind
of famous during COVID because he was one of those
guys who was willing to come out and you know,
speak truth to power, as they say. And Marty's problem
is that he was right pretty much all the time,

(00:32):
and whoever they are didn't want to hear it. Hi, Marty,
welcome back, Good to see you.

Speaker 3 (00:39):
Good to see it.

Speaker 2 (00:39):
Ross.

Speaker 1 (00:41):
In my tenth grade ap biology class, we learned of
islets of languerhands.

Speaker 2 (00:49):
Do you transplant those?

Speaker 3 (00:53):
Yes, we do right now, just within the same patient.

Speaker 4 (00:57):
So if somebody has a chronic pank titus that's stabilitating,
we'll take out their pancreas, separate the islets, and then
give them back to the same patient.

Speaker 1 (01:07):
Wait, did they come out of a pancreas They do?
They live in a pancreas, normally, So where do you
put them if you're taking out the pancreas.

Speaker 4 (01:17):
So this is the key part of the pancreas that
makes insulin, And so we take out the pancreas, tease
out just the insulin producing cells that are in the islets,
and then transplant them back to the same person.

Speaker 3 (01:29):
And we're doing this in part to help people.

Speaker 4 (01:31):
Who have inflamed pancreas disease, but also because we think
there's a potential cure for diabetes there someday.

Speaker 1 (01:40):
All right, so I know we're supposed to talk about
your book. We'll get there in one second, I promise.
So are you are you? Are you removing the whole pancreas,
and if so, then where do you put the replacement
islets when you transplant them back?

Speaker 2 (01:53):
Yeah, we do.

Speaker 4 (01:54):
Remove the whole pancreas, and then when we transplant the
key islet cells back, we transplant it into the liver
where they implant and live for years there, many times
on their own.

Speaker 2 (02:06):
Well. Yeah, so I was pre med in.

Speaker 1 (02:09):
Both my parents are doctors, so that's why I'm a nerd.

Speaker 2 (02:13):
So thank you for thank you for going with me
on those questions.

Speaker 1 (02:17):
Doctor Marty McCarey's new book is called blind Spots. When
Medicine gets it Wrong and what it means for our health.
And I want to start with kind of a macro question.
And you mentioned early in your book something that's important
in life and probably especially important in medicine, and that's
the idea of keeping an open.

Speaker 2 (02:38):
Mind to new ideas.

Speaker 1 (02:40):
Do you think the field of medicine is more closed
than other places to new ideas or just more closed.

Speaker 2 (02:47):
Than it should be to new ideas?

Speaker 1 (02:50):
Well?

Speaker 4 (02:50):
On certain ideas, they get fixated on things and we
develop these giant blind spots. For example, they were fixated
on the idea that opioids were not addictive for twenty years.

Speaker 3 (03:02):
That ignited the opioid epidemic. They got fixated on the
idea that kids.

Speaker 4 (03:06):
Should avoid peanut butter until they turned three. Well, that
abstinence recommendation was dogma, it was wrong, and it ignited
the moderndapediad algae epidemic.

Speaker 5 (03:15):
And with food, we've had this giant blind spot of
all of these chronic diseases going up, all of them diabetes, autism, obesity, autoimmune.

Speaker 4 (03:26):
Diseases, cancer, and the giatarch. They're all going up, and
they've been going up over the last fifty years. But
we instead have been just so focused on demonizing fat
and this old broken food pyramid that was in part
written by the industry that we've developed this blind spot
about the root cause.

Speaker 3 (03:45):
Of all of our chronic diseases increasing.

Speaker 1 (03:49):
It just reminds me of a little thing I mentioned
to you.

Speaker 2 (03:52):
Both my parents are our doctors.

Speaker 1 (03:54):
My dad's a surgeon and my mom's a pediatrician, and
I'm a child of basically of the seventies, and at
some point my mom heard whatever it was they were
saying and switched us from butter to margarine. And later
in life she came.

Speaker 2 (04:13):
Back to me.

Speaker 1 (04:13):
She remembered that, and she came back to me and said, Ross,
I apologize like that was wrong, But it's a small,
mostly harmless example of what you're talking about.

Speaker 2 (04:24):
But it's still right there, Giah.

Speaker 4 (04:28):
Margarine was a total disaster, and it's basically just a
bunch of chemicals to replace natural fat. And so when
we get sort of fixated on things, when we get
this herd mentality among medical scientists, what we're not doing
is challenging deeply held assumptions. We're not talking about, for example,

(04:49):
our poisoned food supply. We're not talking about the role
of pesticides and seed oils and all the damage it
does causing general body inflammation. We haven't talked about refined
carbohydrates in ultra processed foods. Instead, we just focused on
demonizing natural fat, avoid fat, eat a low fat diet.
And so what happens is we can do tremendous damage

(05:12):
by ignoring the role of gut health and the microbiome and.

Speaker 3 (05:16):
Other things like that.

Speaker 1 (05:18):
We're talking with doctor Marty McCarey. This book is called
blind Spots When Medicine gets it wrong and what it
means for our health. And I will just note in
passing and Marty, I'm not asking to come in on
this part. There are a lot of people out there
who put out books that say this and that about
health and diet and whatever.

Speaker 2 (05:33):
Most of them are quacks.

Speaker 1 (05:35):
They're just you know, they don't have anything better to
do with their time, they don't have a real job,
and they're trying to make a few bucks selling books.
McCarey is the real deal, one of the best doctors
at one of the best medical institutions in the world.
And that's why I'm having him on to talk about
these various things. Now, Marty is the son of a pediatrician.
I have always believed in what you in the book

(05:58):
called the dirt theory, right, I've always believed in the
dirt theory. I've I.

Speaker 2 (06:04):
Long thought, from.

Speaker 1 (06:05):
The first time I heard of it, that the guidance
against exposing kids, even in utero, to peanuts was insane.

Speaker 2 (06:14):
It didn't make any sense to me. And I'm not
a doctor.

Speaker 1 (06:17):
And of course sometimes something that makes sense can be wrong,
and sometimes something that doesn't.

Speaker 2 (06:21):
Make sense can be right.

Speaker 1 (06:22):
But I always thought that was nuts. And now here
we are. But the worst thing is how we got here.
Can you talk about that? Well?

Speaker 4 (06:28):
The United States says the worst peanut allergy epidemic in
the world doesn't even exist in Africa.

Speaker 3 (06:34):
And parts of Europe and other parts of the world
because in the.

Speaker 4 (06:37):
United States, for most of the last twenty five years,
the medical establishment gave parents the wrong guidance. They told
parents to make sure kids avoid peanut butter until they
turned three. And what that did is it created a
sensitive immune system in a generation of kids. It didn't

(06:59):
prevent peanut autogies. Avoiding peanut butter early in life caused penodalogies,
and so it ignited this massive surge of kids now
with severe pena analogies coming to the emergency room with
penodalogy reactions.

Speaker 3 (07:14):
And they're real. We shouldn't mock them.

Speaker 4 (07:16):
But this is by and large a byproduct of medical
dogma from a small group of elites at the American
Academy of Pediatrics. I interviewed some of them for the book,
and they were just winging it. They were flying by
the seat of their pants. They should have done a study.
The study eventually got done eight years ago, it was published,

(07:38):
and it showed they got it tragically backwards.

Speaker 1 (07:42):
So I want to focus on this a little bit more,
and you do in the book, including I think, if
I remember right, you interviewed the guy who wrote, you know,
quote unquote the study, and it's it's not just kind
of sad that we have all these people with potentially
deadly out allergies. Now, it's infuriating how that actually became

(08:05):
a recommendation, even more than the fact that they were
recommending something.

Speaker 2 (08:08):
That was wrong. How did it become a recommendation.

Speaker 4 (08:12):
I went back and asked some of these doctors, you
didn't know what caused peanutollergies, you didn't know how to
prevent it.

Speaker 3 (08:20):
So why did you just make it up.

Speaker 4 (08:22):
That parents should make sure kids avoid peanut butter until
they turned three? Why did you just invent this? And
they gave different excuses, but ultimately they made it sound
like people were asking us as experts, So we felt
like we had to tell them something to do even
though they didn't know. Well, I said, no, you don't.

(08:43):
You don't have to say something if you don't know,
the right answer can be we don't know. And when
you don't show that humility, you lose public trust. And
we just saw that during COVID.

Speaker 1 (08:54):
We got about four minutes left. I want to get
to a couple of other things. My wife is at
an age where menopause may soon become an issue, and
she has heard and I have heard her talking about
this supposed risk of hormone replacement therapy for women to
deal with menopause causing breast cancer.

Speaker 2 (09:15):
You address this in the book What's the Truth.

Speaker 1 (09:18):
Well.

Speaker 4 (09:18):
Hormone therapy that is, a woman taking estrogen or estrogen
plus progesterone when they go through rymenopause has tremendous health benefits,
not just alleviating the symptoms of menopause like the hot
flashes and night sweats, but also long term health benefits,
cutting the risk of heart attacks in half, reducing the

(09:38):
risk of Alzheimer's by thirty five percent, reducing the risk
of cognitive decline, women have stronger bones. The benefits are
overwhelming for women. But a guy twenty two years ago
made an announcement that it causes breast cancer. I think
he misrepresented his own data. I go through it in
the book, and women need to know the truth because

(10:00):
to this day, eighty to ninety percent of doctors will
refuse to prescribe hormone therapy for perimenopausal women saying that
it causes breast cancer, citing this guy in his announcement.

Speaker 1 (10:11):
And as far as your own research shows, there is
no science behind the claim that there is a causal
relationship between HRT and breast cancer.

Speaker 2 (10:20):
Is that what you're saying?

Speaker 3 (10:21):
That's right?

Speaker 4 (10:21):
And even when I interviewed the guy who made the
announcement and pressed him, he acknowledged to me that no
study has ever found that hormone replacement therapy increased at
the risk of breast cancer mortality.

Speaker 1 (10:32):
All right, just sticking I guess with women in breasts
for a minute. I remember and you talk in the
book about this sort of panic over silicon breast implants
is and I you know, I'm sure lots of women
are still getting breast implants. I have no idea whether
there's still silicone. I don't really know much about that world.

(10:53):
But what's the story with that? Was there ever a
legitimate reason for there to be a scare about that?
Because they were telling all kinds of horror stories, like
there was all this autoimmune stuff and whatever.

Speaker 4 (11:05):
Well, Connie Jung had a popular TV show back in
the day, and they she had on these disabled women
who claimed they couldn't walk and they were on all
these meds because they had silicone breast implants. Well, all
the research you eventually got done, there was no association
with chronic.

Speaker 3 (11:21):
Diseases and autoimmune diseases.

Speaker 4 (11:24):
The FDA had helped with this pile on where they
actually banned the implant and for years nobody could get it.
The irony is, around that time they approved OxyContin for
chronic pain, even though they only had a fourteen day
follow up study, and to this day three percent of
American adult women have a breast implant, and silicone is

(11:47):
the implant of choice.

Speaker 2 (11:49):
Well all right, well, just about out of time. I
want to end on a.

Speaker 1 (11:53):
Slightly different note that you talk about in your book
that I really enjoy, But just do this sort of
quickly here because I'm going to go a little bit
over time. But I love your stories about people who
are actually open minded and creative and listened to others.
Doctor Lynde, doctor Jenner. Maybe I don't even know. Was
gender actually a doctor?

Speaker 4 (12:13):
Maybe?

Speaker 1 (12:13):
Well, I don't know. But what's your favorite one of
those stories?

Speaker 4 (12:18):
I would say it's the guy who first said that
blood circulates and they didn't think blood circulated in the day,
and they burned him at the stake. Now, he had
also criticized John Calvin, which was a big mistake. But
there are a lot of these amazing stories of how
we got vaccines, the first vaccine that was invented, how
they treated scurvy which had killed millions of people when

(12:40):
they crossed the ocean, and it's.

Speaker 3 (12:42):
The same story.

Speaker 4 (12:43):
A sort of arrogant medical establishment doesn't want to acknowledge
they have it wrong, and when the evidence is clear,
they don't apologize. The establishment just kind of fades out
and people are left confused for decades about what the
truth is.

Speaker 3 (12:58):
And I wanted to write this.

Speaker 4 (12:59):
Book because people need to know the truth about so
many areas of help, and a bunch of us are
doing it now as doctors Casey means Peter Attia.

Speaker 3 (13:06):
We're going directly to the public to.

Speaker 4 (13:08):
Try to tell them the truth about so many of
these controversies that leave people confused.

Speaker 1 (13:13):
Folks that want to encourage you to get Marty mcarey's
new book, it's called Blind Spots. When Medicine gets it
wrong and what it means for our health. Again, I'm
going to repeat something I said before. There are a
lot of people out there who try to write in
this category who have no credentials, don't do any real research,
are trying to sell their own supplements and stuff like that.
There are very few people who can be trusted in

(13:35):
this realm. Marty McCarey is one of those few, and
the stuff that he writes about here is really important.

Speaker 2 (13:41):
Go buy the new book.

Speaker 1 (13:41):
It's called Blind Spots by doctor Marty McCarey. Marty, thanks
for your time today. As always, we'll talk again, thanks
so much, Ross,
