00:00 Introduction and Feedback on Prunes 04:57 Concerns About the High Carbohydrate Content of Prunes 09:14 Considerations for Incorporating Prunes into the Diet
are you looking for the best dietary
tool to improve bone health about 10
months ago I published a video on a
study that used prunes as an
intervention for bone health and it's
been viewed over 37,000 times we've
received a bit of feedback that I would
like to address I also want to update
you on our position on prunes with our
HSN members and our patients so if you
are somebody who's been using prunes and
you have a story about them leave us a
comment on YouTube love to know your
thoughts and your experience
okay so before I get into kind of our
updated recommendations here let me just
review the study again you can watch the
old video but let me just do it in short
here so this study was looking at the
impact of two different dosages of
prunes on bone health in postmenopausal
women over the period of 12 months so it
was a really great study design because
it was 12 months long randomized control
trial the participants were
postmenopausal women aged 55 to 75 and
they had to have a bmd of up to or down
tog -3 although they could have as low
of bmd as zero so this isn't necessarily
a postmenopausal osteop prodoct group
although many of them were uh in the
osteoporosis range they compared 50 g of
prunes versus 100 grams of prunes versus
a control group so again three groups
the 50 g is around four to six prunes
depending on the size and 100 G is 10 to
12 which is potentially arguably a lot
of prunes that might be part of the
issue that we're going to talk about
here essentially they wanted to evaluate
the impact of the prunes um and look at
bone material density at various sites
during the 12 months they also looked at
body comp because they were getting aexa
and they looked at igf-1 as a biomarker
for being anabolic or catabolic Etc so
from a bone mineral density perspective
the 50 g per day prune dosage was
effective at preventing loss of bmd now
let me just clarify what I'm saying
there it was effective at preventing
loss not increasing bone burrow density
so slowing down bone loss which is still
a win but when people say my you know
I'm using prunes and they reverse
osteoporosis not exactly because that's
not what the study shows in the 50 gr
group there was high compliance meaning
that over 90% of the people that were in
that group continued to take 50 g or
four to six prunes per day that was not
true in the 100 G per day group so 10 to
12 prunes maybe too many to eat my guess
is probably some gut dysfunction
diarrhea Etc there a lot of fiber Al a
lot of prunes what they noticed across
the board from a biomarker perspective
is that igf-1 went up and I think that's
really important I'll explain why in a
second additionally on dexa they were
looking at bone mineral density but also
they noticed that fat mass and body fat
percentage over time went up so is that
related to the prunes maybe we're going
to talk talk about why that may or may
not be an issue and then overall this
was kind of a win for prunes right so if
I was a a prune farmer then I would be
excited but there's a there's always a
clinical relevance to any intervention
you know how how do we incorporate this
in to our patients lives and then what
is their experience and how does that
work for them so I want to give you that
side of this rather than just talk about
the science at this point before I do
that though let me just say that if you
are still trying to put together your
program and struggling with your results
consider coming to our free Master Class
free master class is where we go over
how we are putting it together for our
patients at this point in time and then
there's a a Q&A session at the end 10 to
15 minutes to get questions answered
that is really the pathway that if you
are new to or struggling with
osteoporosis can be such a Time
collapsing event where you can learn
about so many different Tools in one
place so if you want to register for
that just go to the description below on
YouTube or go to Optimal human
health.com and you can find a link on
that website right there so let me fill
you in on a bit of a secret my team at
optimal human health for our bone health
program is not just me I do see patients
but the majority of our program is
handled by our provider team of Pas and
nurse practitioners as well as our
dietician coaching team which currently
we have about eight I believe seeing
patients all day long every day so my
team really hates it when I drop little
truth nuggets like prunes are good for
osteoporosis like this without
consulting them first and so as I said
that video that I posted 10 months ago
has been viewed 37,000 times so there
might be a lot of people eating prunes
that didn't used to those are including
our patients because our patients
obviously are watching our videos so why
is that a bad thing if it slows down
bone loss well one of my dieticians
brought this up to me and she brought it
up a couple of times and finally I I
paid attention and really looked into
the details and so her concern is that
50 gr of prunes is pretty carb heavy now
everybody has a different carbohydrate
Toler
but prunes in particular cuz they're
fruit they have about 12 to 14 gam of
sugar and 25 G of carbohydrate overall
so it is a carbohydrate heavy snack or
part of a meal depending on how you're
doing it that's the equivalent of adding
potentially up to two tablespoons of
sugar per meal if you're adding these to
a meal so my initial thought on this is
that with the fiber and the whole food
source of the sugar this is probably not
a big deal and I still think for a lot
of people that's true because if you
look at the population of you know our
patients the population of people in
general that have osteoporosis many
people in that group do struggle to
maintain weight to put weight on so I'm
not as concerned about weight gain in
the population at large however not
everybody tolerates that amount of
carbohydrate particularly when you eat
it and how you eat it so the perspective
is this is that adding 50 grams of
prunes could potentially increase your
fasting blood sugar could potentially
increase your A1C hemoglobin A1c is a
measure of blood sugar over time it
could potentially increase the biomarker
of fasting insulin for some people it
can cause diarrhea other kind of
irregular stools going back and forth
for some people it could potentially
provoke weight gain changes in body
composition and I mentioned in this
study they actually did show that there
was an increase in fat Mass on dexa
another concern that my team has is that
if you're adding in prunes especially
that much fiber that you could get F
pretty quickly and that could actually
displace protein in the diet which
you've I'm sure heard me talk about the
importance of that so starting the day
with a carbohydrate dominant meal if
you're using prunes in the morning which
many people do to to help with bowel
movements you might notice that you're
either hungrier sooner like within an
hour um you might have more fatigue you
might have then you know sugar Cravings
carbohydrate Cravings some people
complain of brain fog another concern
that they brought up is that we all have
a kind of a carbohydrate allowance for
the day now some of us measure it some
of us don't but we are all kind of a
carbohydrate allowance and then if
you're using that up particularly
earlier then you're not going to be able
to add other carbs in later that might
have beneficial nutrients in it right so
like the fruit and the the vegetables
and starchy vegetables Etc also if
you're getting all of your calories and
sugar and carbohydrates from One Source
then it's going to reduce variety which
can have an impact on gut health which
is going to impact on bone health and so
really my team kind of looks at these
things I like big fat supplements right
they're just big supplements and I think
that that's kind of true but I want to
balance this out to say that
carbohydrates themselves are not evil
but we do have to understand our
individual carbohydrate tolerance level
some people have got Health limitations
some people can tolerate more less Etc
people that struggle with metabolic
Health meaning that they have elevated
glucose they might be pre-diabetic or
diabetic people that have elevated
fasting insulin levels or that aren't
very active that entire population which
is pretty big that entire population
might not do well with adding prunes so
I was curious how this would impact
somebody who has a relatively healthy
metabolism and so at our last team
meeting I asked our dietitians if anyone
was wearing a continuous glucose monitor
and for those that are familiar with
these things rather for those that
aren't the glucose monitor or CGM is a
way to measure glucose over time and you
can do it accurately every you know I
think 2 minutes or 3 minutes whatever
the inter is but you can watch what
happens to your blood glucose after a
meal or eating
anything and so one of our dietitians
was wearing a continuous glucose monitor
at the time and so the next day she
added six prunes to her morning and she
consumed them fasted so consumed them
without anything else in her stomach at
the most insulin sensitive time which is
first thing in the morning and what we
found is that her blood glucose did go
up but not that much I was really
surprised to see that it didn't go over
110 10 and then it came right back down
so from a CGM perspective in this one
individual it did not seem that
significant but what we've heard from
our patients is and what we've seen from
our dietitians is that there are a fair
number of people that don't tolerate
eating prunes so what do we do in our
practice well we discuss prunes but we
don't push prunes again I there are so
many tools that we have that you know
having to add prunin to your diet is is
something that not a lot of people want
to do and that's okay because there are
so many tools that we have at our
disposal so it comes up people watch the
videos it's in our bone foundations
course so you know it comes up and we
talk about it and some people do it I
think that adding prunes to diet is
totally reasonable and that's what I
tell my patients but it has to be done
in the context of metabolic health so
understanding what someone's fasting
insulin and glucose and A1C is is really
important what is the gut health like
what's their activity level if you are
watching this video and you're not
working with us as an HSN member or a
patient remember to ask your own team
before changing something as significant
as this so this video was a review of
prunes and if you like this content you
might consider the video the best diet
for osteoporosis that one is the 2024
update on the dietary recommendations we
make in general for our patients and
then as a in addition to that the video
called the benefits of red meat and that
talks about all the nutrients that are
found in animal sources of protein that
you can't find in plant sources of
protein so that's it and remember please
that osteoporosis isn't the end but
deciding to reverse it is a beginning if
you have already been to our master
class and you want to learn more about
how to manage bone health consider our
bone foundations course totally free you
can get into that of the ebook that
osteoprosis breakthrough that I wrote
and also give you a free month to our
HSN where people get access to myself
and my team to ask us questions about
their own program and also gives access
to a community so tremendous amount of
support there so I hope you found that
helpful I'll see you on the next video
