In this video, we're going to talk about the Kraft insulin survey. We've
mentioned it many times but we've never really gone through a full who, what, why,
when, and where. That's what we'll do in this video. We'll also talk about Joseph
Kraft's book, The Diabetes Epidemic and You. Just briefly, who - who do we do these
for? People who I suspect insulin resistance for one reason or another but
it's not showing up very clearly in the standard tests. Fasting blood glucose,
triglyceride over HDL even OGTT. John Roy Scheider was one of those folks as
we mentioned before. He came in and said, doc you I know you asked about insulin
resistance and prediabetes. I check it every year, my doc checks it every year.
We know what we're doing. We don't have it. We did the Kraft Insulin Survey and
his blood sugar went up over 200, actually close to 300. He
realized at that point that he had not only insulin resistance but full-blown
diabetes and covered that in several of his videos. Now, so those are the kind of
situations where we'd want to look at this. What is it? We'll go into detail on
the tests in just a few minutes. Why? Again, we've covered that in other videos.
Basically, if someone has insulin resistance or full-blown diabetes, they
clearly are not somebody. They should be eating glycemic carbs at will. That's
something they need to be very much familiar with and they need to start
tracking their blood sugars using continuous glucose monitoring like the
freestyle Libre. So, where do you do it? It's - you can be - you can do it from your
own home. We've also worked out something with quests labs where we do something
very similar. It's a 3-hour insulin survey. We've done a couple of videos on
that. Again John covered one. These - I've done a couple of videos where I
actually looked. John's covered the book. Mine covers more of the history and the
test results itself. So the history - it was developed by a fellow named, doctor
named Joseph Kraft. He was a pathologist. The head of a lab, large lab in a large
hospital in Chicago a couple of decades ago. He wrote a book, The Diabetes
Epidemic and You. It was based on quite about 15,000 glucose tolerance tests
that he did in his lab. These folks were people that had been referred to the lab
by their dogs for glucose tolerance testing. Now, he did something a little
bit different. The normal OGTT has 75 grams of glucose. You go in, your - your NPO
or nothing by mouth for 8 hours. Then you go in, you get a fasting glucose and
then a 1-hour. Well, a fasting glucose takes 75 grams of the sugary water and
then tests the blood sugar again at at least 1 hour and 2 hours. The Kraft
prediabetes profile or insulin survey is different in a couple of ways. You
still do the nothing by mouth for 8 hours. You still do the fasting blood
sugar but instead of a 75 gram drink, you get 100 grams of glucose in that
drink; and instead of 2 hours, you get 3 hours or even a 4-hour test. And
instead of just looking at glucose, every time you're drawing blood you're also
looking at insulin. So we can follow the insulin pattern and the amount of
insulin that your body is putting out in order to manage that blood sugar. It's a -
you can do - do this at home through one of our - one of the labs that we work with.
Meridian Valley lab or we now have something that we've negotiated with
quest labs to get it done in the reference lab. Now, as John mentioned in
his video and and some other folks have said,
well my dog said this was rigged to fail. A hundred grams of glucose well, or even
75 for the OGTT. Well again, one 20-ounce bottle of - of soda is 78 grams of carbs
and guess what, if you go to Mickey D's and get a a value meal, you get
190 carbs. 95 of those are sugars so you got to watch out and think a
little bit more deeply about what you're eating and what you're drinking. Now,
let's go into the the results of the - the book and the chapters itself. I wanted to
cover some of that with you. So you begin to understand why we keep referring back
to this book. Out of those - of what, 14,000 tests that he did, he
kept fairly good numbers and we'll go through some of the translation on what
he saw. He - each chapter of about, what chapters 31 through 35 or so, looks at a
decade of life. So in other words, this is the decade of life 51-60
year olds. In the number of - of these Kraft Insulin surveys, he did where there
were inpatients 51-60 was 2413. The number out of that, that had a normal
glucose tolerance was 1,300. So just over half had a normal glucose tolerance.
Impaired tolerance was 602 and diabetes, full-blown diabetes was 508. The mean out
of that group was 56 years and it goes on to tell how many women, how many men
tell us a little bit more about the procedure itself and it says, the
procedure was ordered by the physician to exclude or diagnose prediabetes or
diabetes. Now, here's a little bit of confusion and I will try to clear that
up for you. The results were critiqued with the American Diabetes Association
guidelines for fasting blue blood glucose and oral glucose. So what he's
saying here is this. They looked at the fasting blood glucose. If it was less
than a hundred ADA guidelines said you didn't need to be testing any further so
you didn't need an oral glucose tolerance test. If that had - had been
applied to this group of 51-60 year olds, 69% would not have been
tested. So 69% of these people had over or had a fasting blood glucose of
a hundred or less. So again, most labs would say, well you don't need to do
an OGTT. Well, again as he showed in the beginning, almost half of them had an
abnormal glucose tolerance test. So - or a Kraft Insulin Survey. So that's the point
that you begin to see and actually even docs and standard medicine these days
understand, fasting blood glucose by itself is not an adequate test. If you
look at mine for example, in March of 2019, my fasting blood glucose was 84. It
looked great but at 1 hour post oral glucose tolerance or post 75 grams of
sugar, my blood sugar went up to 184 so I'd be in one of those groups. That's
just to repeat on those. Let's look at oh no - it's not - it's the 41 to 50 age group.
So as you see, one of the things that you'll see as I go through these next
few chapters, is this is very much an age-related issue. I've said many times
in many different videos. Most of us tend to think, well the diabetes and
prediabetes epidemic is really caused by obesity, and I keep saying, if you look
at aging, aging is probably a bigger issue. The fastest growing group of
of Americans as centenarians, hundred year olds; and let's look at aging over
the next 3 or 4 slides. 41-50 year age group. Out of 1925, the normals
were a hundred - 1231. So again, that's significantly
over half for normal there. Maybe what, 60%. Actually over 60%. In the
51-68 group which would cover just a few minutes ago, now that's dropping. It's
1302 normals over 2400. Getting a little bit closer to half.
Okay, now that we get up to the 61-70 year age group, 827 normal out of
1720 and pardon me, these numbers have gotten moved
around a little bit in is 1720. Normal glucose was 827.
Impaired glucose was for 64 and full-blown
diabetes glucose intolerance was 429. So as you can see, at this point between
ages 60 and 70, less than half have a normal insulin resistance or OGTT Kraft
Insulin Survey or more than half have insulin resistance or prediabetes. You
know what, you remember the book that we've mentioned many times, it's Ginny
Rule Blood Sugar 101 where she says, look by the time we're age 60, half of us have
insulin resistance. That's from experience that they've seen
with tens of thousands of diabetics; and if you look at numbers from the CDC, just
using hemoglobin A1c and fasting glucose, those numbers would indicate it's 1/3 of
all adults, age 32 and above in the country or 84 million of us. If you
look at the UCLA study in California, it's over half have prediabetes starting
at age 30. So you start looking at these numbers and you start realizing, dang, if
you did an insulin - Kraft insulin survey on these people, how many more would you
find with insulin resistance and as you start looking at age groups what's going
on there? In the 71-80-year old age group, this is - you look at this and okay
out of a total n of 932, the - the normals were what just over a third. So 2/3
of the people had insulin resistance and or complete diabetes. So
again, I hope that helps give you some perspective. Now it's not entirely
comparable and before you start saying, we'll wait a minute Brewer, those - let's
just stop and and think just a minute. How were these numbers obtained? These
were docs referring a patient where they had some sort of suspicion. So the
numbers are not totally comparable to either the CDC or the UCLA numbers. And
the CDC and UCLA numbers are not totally comparable but again what they do show
is significant increase in insulin resistance and diabetes as we age and
they also show the - the old normals or the old tests like fasting blood glucose
just are not adequate. The 81-90 year old group out of a total of 210, only 65,
less than a third at this point have normal glucose tolerance. So one other
thing that he showed in his, as he went back and analyzed these numbers and
these, what, 14,000 tests that he did was some significant patterns; and these
patterns you see, because it's an insulin survey. In other words, he kept getting
the insulin tests at the same time he was getting the glucose tests. This is a
normal at zero or fasting blood sugar, blood sugar's around 80. After a half
hour went up, peaked at about at 120. Came down to just around a
hundred for 1-hour and the 2-hour and then dropped down below to 80
or so. At the same time, blood - blood insulin went from 2 or 3 up to
50 at peak and then again began to come back down.
That was normal pattern. Pattern 2, the blood sugars started going up to 140 and
this was at an hour. It was delayed, as you can see, the next 3 patterns do
show a delay. A half-hour delay, a 1-hour delay, and a 2-hour delay. Now what
does that mean, well there are different levels. Again, if you read Ginny Rules'
book, there are different levels of a different time periods of insulin
response. Our body does store insulin, so when we get challenged with an
increasing blood sugar, there's an immediate release of that stored insulin
and then after that, the pancreas begins to make more insulin. So what you're
seeing here, appears to be decreased, further and further decreases in that
stored insulin response; and what's happening then is it's taking longer and
longer in patterns 2, 3a, 3b and - and well 3a and 3b to get that insulin built up
so it takes in the blood sugar down and manages the blood sugar. Now he's - he
showed pattern 4 as well where the numbers went way up, went to like what,
250 for blood sugar and also went way high for insulin as well and that he
labeled as hyperinsulinemia. So that is actually true resistance, where your
blood sugars are going up, your insulin values are going way up as well but your
blood sugars are just not coming down. Now that's considered to be a late stage
of pre-diabetes or insulin resistance, in fact, that is often coming right before a
time when the beta cells in the pancreas have just worn out, they're not making
insulin anymore, are significant amounts. With that pattern, insulinopenic is
what they call it, penia meaning very little. It's making very little insulin
at that point. The blood sugar is going up to 300, meanwhile, the insulin is still
not making it up to 50. So I've traveled very quickly through this survey. Some of
it may sound a little bit confusing. If it is, please make some comments below
and I'll see if I can clear those up. If you've made it this far, thank you again
