English transcript

00:0X all right our next speaker is Bill I say
00:0X William B Grant has a PhD in physics
00:0X from the University of California Berkeley
00:1X in 1971 he has had a 30-year career in
00:1X atmospheric sciences with an emphasis on
00:1X laser remote sensing of atmospheric
00:1X constituents such as ozone and aerosols
00:2X with positions at s RI International the
00:2X Jet Propulsion Laboratory California
00:2X Institute of Technology and NASA Langley
00:3X Research Center he turned to health
00:3X research in 1996 publishing the first
00:3X paper linking diet to risk of
00:4X Alzheimer's disease in 1997 followed by
00:4X his studies of sugar fat and coronary
00:4X heart disease in 1998 and animal
00:4X products and cancer risk in 1998 in 1999
00:5X he turned his attention to the role of
00:5X solar ultraviolet B exposure in reducing
00:5X risk of many types of cancer through
01:0X production of vitamin D in 2012 after
01:0X retirement from NASA in 2000 2002 after
01:0X retirement from NASA in 2004 he moved to
01:1X San Francisco and formed the nonprofit
01:1X organization sunlight nutrition and
01:1X health research center which is WWN arc
01:2X AR CSUN AR c.org where he spends most of
01:2X his time studying the role of UVB solar
01:3X UVB exposure and vitamin D in reducing
01:3X risk of cancer and many other types of
01:3X disease he also investigates the role of
01:3X diet in risk of Alzheimer's disease in
01:4X cancer he has about 300 health
01:4X publications listed at WWE become of
01:4X which 210 are related to vitamin D with
01:5X 78% of these also on ultraviolet
01:5X radiation in human health and 41 to diet
01:5X and disease please welcome Bill Graham
02:0X thank you I'm delighted to be back here
02:0X again I really have enjoyed this
02:1X organization I like cork you invited me
02:1X into it about 12 or 13 years ago and
02:1X I've didn't involve ever since but don't
02:1X come to meetings very often now because
02:1X it's I'm in the San Francisco and it's a
02:2X long way down here and back let's see
02:2X there you go
02:2X I do receive funding from biotech pharmacal
02:3X that's a vitamin company as a
02:3X supplier of research grade vitamin D for
02:3X health professionals and consumers they
02:3X have a website biotech for McHale calm
02:4X so I'm going to discuss a number of
02:4X topics related to vitamin D this evening
02:4X first of all the vitamin D physiology
02:4X then I'm gonna put the binding
02:5X recommendations right up in front
02:5X because I think that's what you're most
02:5X interested in then I'll tell you why if
02:5X I'd be is important in terms of which
02:5X health outcomes are related to low
03:0X vitamin D whereas the Bundy policy
03:0X hitted so my latest research on how
03:0X vitamin D clinical trial should be
03:1X conducted and then tell you where to go
03:1X for additional information so vitamin d3
03:2X that's cholecalciferol can be made in
03:2X the skin or obtained from a food of
03:2X supplements there's also a vitamin d3
03:2X aerial cuss difficult which is made from
03:3X mushrooms or yeast or fun gene that's
03:3X not as effective as vitamin d3 it
03:3X doesn't last as long and it's not clear
03:4X that it has the same health benefits but
03:4X some people were vegans want to have no
03:4X animal products and all vitamin d3 is
03:4X made from animal products or almost all
03:4X there is a power plant source vitamin d3
03:5X but the vegans often want to go with a
03:5X d2 the liver converts vitamin d3 to – – –
03:5X hydroxy vitamin d3 by adding a hydroxyl
04:0X group and this is what is measured when
04:0X you go to the doctor's office and wonder
04:0X what your your blood level of vitamin D
04:1X is the half-life of this 25 hydroxy
04:1X Vaadin D is about two and a half
04:1X weeks now a kidney converts the 25
04:2X hydroxy body to 125 diet dihydroxy of
04:2X vitamin D and this this and the
04:3X parathyroid hormone PTH helped keep
04:3X serum calcium within a tight range the
04:3X 125 increases calcium absorption from
04:4X the intestines whereas a PTH increases
04:4X calcium absorption from the bones so we
04:4X have sort of a push and pull and so it's
04:4X there's not a direct correlation between
04:5X the amount of 25 and 125 but the more 25
04:5X you have the more 125 you can make there
05:0X are other actions of vitamin D and
05:0X that's what I primarily study most of
05:0X the action of vitamin D is through the
05:0X 125 entering the vine D receptors which
05:1X are coupled to chromosomes in there
05:1X every cell of the body when activated
05:1X the VTR's control the expression of many
05:2X genes up regulating most of them down
05:2X regulating others and it turns out that
05:2X not only a kidney can convert the 25 to
05:2X 125 but also other organs as needed
05:3X so for example you cancer someplace the
05:3X cells in that organ can also convert the
05:3X 25 to 125 and the skin it can convert 25
05:4X to 125 now Von D also fights bacterial
05:4X and some viral infections by inducing
05:5X production of Catholics seitan that's
05:5X the polypeptide with antimicrobial and
05:5X anti endotoxin properties fine B also
05:5X induces reduces inflammation by reducing
06:0X a production of pro-inflammatory
06:0X cytokines which are chemical messengers
06:0X to underscore the importance of vitamin
06:1X D for human health I note that skin
06:1X pigmentation varies globally depending
06:1X on where people live for hundreds to
06:1X thousands of years for example the the
06:2X Aborigines in Australia are very
06:2X dark-skinned their ancestors were from
06:2X the force of the Indonesia where
06:2X where they were brown-skinned but when
06:3X they got to Australia with no trees to
06:3X cover them they needed a very dark skin
06:3X to protect them from the very very
06:3X intense UV so dark skin in the tropics
06:4X reduces the risk of free radical
06:4X formation and skin cancer as well as
06:4X protecting against folate destruction
06:4X and folate is very important for
06:5X pregnancy and for pregnancy now as
06:5X humans moved out of Africa started
06:5X moving in northward they had to develop
07:0X lighter skin in order to make enough
07:0X vitamin D from the from the less intense
07:0X UV and they didn't need the protection
07:0X of the dark pigment against the free
07:1X radicals and full of destruction what
07:1X would happen they would get more
07:1X infectious diseases like tuberculosis
07:1X they would also get more rickets and
07:2X poor bone formation and so then the
07:2X pelvic cavity wouldn't be large enough
07:2X to let a feed on an infant come out in
07:2X the birth process and they hadn't
07:3X invented c-sections thousands of years
07:3X ago now Nina Jablonski and George
07:3X Chaplin and made a career out of going
07:4X around the world and measuring the un--
07:4X UV exposed pigment in many peoples
07:4X around the world and they have this
07:5X developed this map of skin pigmentation
07:5X they see very dark in the tropics where
07:5X you have no trees brown lighter color in
08:0X the tropical forest and very light in
08:0X the high latitudes so now let's go to
08:0X recommendations which I gave a talk in
08:1X Hungary last month and after I gave all
08:1X the information about what the benefits
08:1X are all I wanted to know was well how
08:1X much do I need how much should i what
08:1X should my level be so in 2011 the
08:2X Institute of Medicine announced that
08:2X adults up to the age of 7 years old
08:2X should have 600 ru per day over 70 years
08:3X they should have editor ru per day and
08:3X that 20 nanograms per milliliter vitamin
08:3X D concentration was 25 hydroxy vitamin E concentration
08:4X was just fine well it turns out that
08:4X that was a not a very sound study first
08:5X of all they were this was funded by the
08:5X Food and Drug Administration and the
08:5X National assistive health and Health
08:5X Canada and the two US organizations
09:0X worked very closely with Big Pharma and
09:0X also one of the organizers one of the
09:0X people on the committee had planned
09:1X another major vitamin E clinical trial
09:1X where people could take we're gonna take
09:1X 2000 IU of vitamin D per day in the
09:1X treatment arm but they got all my in the
09:2X treatment or the control arm could take
09:2X as much as the Institute of Medicine
09:2X recommended so in order not to sabotage
09:2X her clinical trial she pushed I think
09:3X very hard for these recommendations but
09:3X in order to reach these recommendations
09:3X they did three things which which are
09:3X not very scientific
09:4X first of all they ignored all non
09:4X skeletal effects they ignored cancer
09:4X cardiovascular disease autoimmune
09:4X diseases respiratory infections etc
09:4X second they demanded published
09:5X randomized controlled clinical trials of
09:5X a vitamin D and at a time when they did
09:5X a study all I could point to was
10:0X clinical trials for bone health
10:0X the third thing they did was they took a
10:0X study from Germany which looked at
10:0X people who died in automobile accidents
10:1X so they're healthy people just happen to
10:1X die prematurely and in the study they
10:1X they looked at the osteoid amount of the
10:2X bones noted as the unn mineralized
10:2X calcium in the bones sort of liquid or
10:2X gelatin life and they also compared the
10:3X 25 hydroxy vitamin D concentrations with
10:3X with the amount of this poor bone
10:3X mineralization and what they did was
10:3X they ignored the findings between 20 and
10:4X 30 nanograms in terms of they still had
10:4X a few at that point who had on
10:4X mineralized bone but they said that
10:5X wasn't important that most of the people
10:5X with underlies bone were below 20
10:5X nanograms so we're gonna stick with 20
10:5X he has been shown in many comments later
11:0X on that that was a major mistake and I
11:0X think the Institute of Medicine now
11:0X realizes that yeah but it took quite a
11:0X few years then I realized that now in
11:0X 2011 The Endocrine Society led by
11:1X Michael Holick team led by Michael
11:1X Holick published a recommendation for
11:1X dealing with a vitamin D deficiency now
11:1X it's the first one the Institute of
11:2X Medicine was for the general public healthy or not
11:2X the endocrine Society was dealing with
11:2X with people being treated by doctors
11:2X fortified in D deficiency so they
11:3X recommended a 1000 2000 IU per day of
11:3X item d2 or d3 and a serum vitamin e
11:3X concentration of around 30 nano grams
11:4X per milliliter at least they considered
11:4X 20 deficient between 20 and 30
11:4X insufficient above 30 sufficient however
11:5X there are finally advocacy organizations
11:5X which I'll name at the end who have
11:5X looked carefully at the the general
11:5X literature that comes out on a daily and
12:0X a weekly basis and have some of these
12:0X people have written peer-reviewed papers
12:0X on the benefits of item D and they've
12:0X looked at people with higher
12:1X concentrations and and how much better
12:1X they do in terms of athletic performance
12:1X or lack of disease and they're
12:1X recommending around 2,000 to 5,000 IU
12:2X per day vitamin d3 not skipping vitamin
12:2X d2 and a serum concentration of around
12:2X 40 to 60 nano grams per milliliter
12:2X one of the reasons for saying 40 to 60
12:3X is that looking at healthy Africans
12:3X modern-day Africans who are outdoors
12:3X every day with dark skin with with some
12:4X clothing I mean they're not not just
12:4X annoying Clause but they have a fair
12:4X amount of clothing on they have around
12:4X forty five nanograms per milliliter
12:5X serum 25 hydroxy vitamin D and so you
12:5X have these three recommendations so well
13:0X now just to show a picture here
13:0X Roger bouillon on the on the left is one
13:0X of the most prominent finally
13:0X researchers in Europe believe he's in
13:1X Belgium he's a lot of European leaders
13:1X are the 20 nanograms per milliliter camp
13:2X Michael Holick on the other hand is the
13:2X leader of the 13 anagram plus camp now
13:2X there are three sources of vitamin D the
13:3X sunlight is the primary source this map
13:3X this is a shows on the bottom is a month
13:4X of the year from from January through
13:4X December along the y-axis you have the
13:4X latitude from zero the tropics up to 90
13:5X degrees at the top and the colors
13:5X indicate how much time you have to be in
14:0X the Sun in order to make I see how much
14:0X well let's see if you okay if it's red
14:1X you cannot make any vitamin D if it's in
14:1X the blue the purple range you can make
14:2X some vitamin E it's gonna take longer
14:2X like maybe up to half an hour an hour to
14:2X be in the Sun and if it's black you can
14:2X make it fairly easily so we're about 30
14:3X degrees north latitude here so in the
14:3X winter we have a difficult time making
14:3X vitamin D but by March or April through
14:4X about October we can make a fair amount
14:4X of vitamin D and this this map was 400 – -
14:4X IU of a per day of vitamin D now if you
14:5X need 2,000 to 4,000 5,000 IU per day
14:5X this is the this scale would be changed
14:5X also it turns out that there's there's a
14:5X shadow rule the dermatologist like to
15:0X tell you if your shadow is shorter than
15:0X you are stay out of the Sun or cover up
15:0X or use sunscreen the vitamin E advocates
15:0X like to say unless your shadow is
15:1X shorter than you are you're not gonna
15:1X make much vitamin D so that means you
15:1X want to go out in your solar noon you
15:1X want to go out in the in the summer
15:1X spring summer and fall you want to
15:2X expose as much of your body as possible
15:2X you want to one of the reasons for going
15:2X out midday in addition is that the ratio
15:2X of UVA to UVB changes the shorter the
15:3X wavelength the more scattering there is
15:3X in the atmosphere and the way you can
15:3X tell that is the sky is blue and clouds
15:4X are orange so as a sunset sunrise the
15:4X Sun goes the sun rays go through a very
15:4X very large path and the shorter
15:4X wavelengths are scattering the
15:5X wavelengths much more rapidly than they
15:5X are the long wavelengths so the orange
15:5X gets to the clouds the blue gets to the
15:5X sky well UVB is much shorter than the
16:0X blue and so it's scattered even more in
16:0X fact even if you're under an umbrella
16:0X you're going to get UVB impinging on you
16:0X from the sides the the the the diffuse
16:1X scattering but the UVB the UVA is going
16:1X to be less scatter than UVB in fact UVB
16:1X is about three to five percent of total
16:2X UV and the rest is UVA
16:2X the problem with UVA is that it
16:2X penetrates the skin deeper and is more
16:2X important more responsible for melanoma
16:3X and basal cell carcinoma then UVB is so
16:3X if you went out morning evening you're
16:3X more likely to get melanoma but no
16:4X vitamin D so I was in a hungry last month
16:4X went over there ten conferences in
16:4X Warsaw and Thessaloniki and stopped off
16:5X in Budapest and found this this like a
16:5X porcupine with sign under saying Sun so
16:5X the Sun is one way to get your your your
17:0X vitamin D but you can also get it from a
17:0X solarium the indoor tanning booths maybe
17:0X have two to four percent UVB in the UV
17:1X if you go in for tanning you're going to
17:1X see how much longer they need to for
17:1X vitamin D production it turns out that
17:1X after you make that up to 20 thousand
17:1X international units of vitamin D from
17:2X whole body exposure in a Sun and half an
17:2X hour to an hour the body's that the UV
17:2X starts destroying the metabolites of
17:2X vitamin D so he can never make too much
17:3X vitamin D in the Sun now the other
17:3X sources of vitamin D are supplements and
17:3X diet and in terms of diet its animal
17:4X products like seafood but it turns out
17:4X that that a study in England found that
17:4X the people with the highest vitamin D
17:5X concentrations were not the fish eaters
17:5X it was the meat eaters the vegans had
17:5X the lowest amount the vegetarians a
17:5X little bit higher but there is about a
18:0X 1/8 nanogram per milliliter difference
18:0X between the meat eaters and the vegans
18:0X the reason is that meat has vitamin D as
18:0X 25 hydroxy vitamin D so most of the food
18:1X tables that talk about vitamin D do not
18:1X read do not include that in the study so
18:2X all these food frequency tables and how
18:2X much find here get from fewer eggs and
18:2X from your milk and so on they would find
18:2X about 250 to 300 IU per day in the American diet
18:3X not counting what's in a meat
18:3X and of course 250 and 300 are you per
18:3X day is not enough to to do much now
18:3X there are other effects of UV exposure
18:4X one thing you do is you get beta
18:4X endorphins which help reduce pain and
18:4X help you feel better
18:5X in fact the dermatologists realize that
18:5X people often go to tanning beds on a
18:5X regular basis because they get an
18:5X endorphin high and the claim is that
19:0X they're getting addicted to tanning
19:0X because of the beta endorphins mike my
19:0X thought is that anything that has
19:0X long-term benefits nature and sometimes
19:1X provides short-term benefits to make you
19:1X understand that their long-term benefits
19:1X and so I think there's a you know should
19:1X be applauded rather than criticize
19:2X another thing is you can release my
19:2X trick oxide subcutaneous nitrogen
19:2X compounds which can lead to lower blood
19:2X pressure in fact if you look at the
19:3X latitudinal distribution of blood
19:3X pressure it's lowest in the tropics and
19:3X highest in the high latitudes of course
19:3X that could also be related to dietary
19:3X factors but but it could be related to
19:3X some what - to UV there are some we'll
19:4X see multiple sclerosis has a very
19:4X pronounced latitudinal effect and four
19:4X years of thought that that was because
19:5X of vitamin D production but now both
19:5X human studies and and animal studies
19:5X have indicated that there are benefits
19:5X of UV aside from vitamin D production
20:0X that reduced the risk of multiple
20:0X sclerosis of course there are other
20:0X effects you can reset your biological
20:0X clock through the blue light around 420
20:1X nanometers I found out when I went to
20:1X say Sweden in February I was there for
20:1X two weeks and never got on Swedish time
20:1X and last month I was in in Warsaw for a
20:2X week and it rained every day and I did
20:2X not get on Warsaw time finally in in
20:2X Budapest I started with sunlight I start
20:2X to get over on the European time also
20:3X turns out that as I was so later than
20:3X just getting outside and exercising is
20:3X very beneficial and has health effects you
20:4X tentative of vitamin D so those most
20:4X likely to have low vitamin E
20:4X concentrations are those spending most
20:4X time indoors this will also include
20:5X those who have do shift work and sleep
20:5X during the day because they work at
20:5X night not being the Sun nurse solar noon
20:5X went with sufficient body surface
20:5X exposed dark-skinned people I'm working
21:0X on a manuscript on the health benefits
21:0X of vitamin D for dark-skinned people in
21:0X the United States we're going to Bruce
21:0X Ames on this and see if the average the
21:1X mean casa
21:1X 25 hydroxy vitamin d concentration for white
21:1X adult American Americans is around 21 ?
21:2X nanograms per milliliter of course our
21:2X seasonal variation is gonna be a factor
21:2X of 2 between summer and winter for
21:2X Hispanics is more like 21 nanograms and
21:3X for black Americans and more like 1 ?
21:3X nanograms so yeah in Africa they had all
21:4X the vitamin E they needed but not here
21:4X in the United States those who are
21:4X overweight or obese I generally have
21:4X much lower body concentrations than
21:4X those who are normal weight wearing
21:5X sunscreen or even wearing using skin
21:5X lightening cream reduces the vitamin E
21:5X production and it turns out older folks
22:0X over the age of 60 and perhaps even
22:0X little bit younger have less of the 7 d
22:0X high high low cholesterol in a thinner
22:0X skin that that is converted to two
22:1X vitamin D and salami didn't may need to
22:1X stay in the Sun two to three to four
22:1X times longer to make the same amount of
22:1X vitamin D so there are values of
22:2X measuring 25 hydroxy vitamin D and also
22:2X turns out that even if you take a
22:3X thousand or 2,000 I you if I marry per
22:3X day there's a large variation in the
22:3X response to to vitamin D some people may
22:4X make twice as much 25 from the same out
22:4X of oral vitamin D and turns out it
22:4X depends on whether you take it with a
22:5X large meal so it goes slow
22:5X intestines whether you're taking more
22:5X magnesium to help conversion 225 etc etc
22:5X so if you really want to know where your
23:0X your concentration is you really ought
23:0X to have your 25 hydroxy vitamin D
23:0X measured you can have your doctor do it
23:0X but you can also go to grassroots health
23:1X net or the Van Dien Council org and both
23:1X of them sell a blood spot kit and you
23:2X get a little Lance you draw three or
23:2X four spots of blood and put it on a card
23:2X there's dried blood just sent back to
23:2X them they they sent it to a laboratory
23:2X and they it's very accurate they use
23:3X Hema they use an average Hema crit value
23:3X for the entire population around well so
23:3X if your Hema crypt is somewhat different
23:4X from from normal that might be a slight
23:4X error but I've checked it out some time
23:4X ago and when I was taking more like
23:4X $5,000 per day and I got 65 67 and 6 -?
23:5X nanograms per milliliter depending on
23:5X the blood spot test
23:5X and two of the wet chemistry labs so I
24:0X think they're quite a Qi accurate
24:0X grassroots health also has a program
24:0X where you can have your your 25 hydroxy
24:0X dividing measured every six months and
24:1X you're then entered into a scientific
24:1X study they want you to stay in it for
24:1X about five years they'll ever ask your
24:1X health question how's your health what
24:1X did you did you fall did you get sick
24:1X etc etc and they've actually used these
24:2X results in several peer-reviewed
24:2X publications so now we get into the
24:2X benefits why you really want vitamin D
24:3X I'm gonna skip bones because I really
24:3X haven't study bones that was sort of the
24:3X classical vitamin D area and it's been
24:3X the last almost two decades now that the
24:4X non skeletal effects have become very
24:4X important and that's what I've studied
24:4X so there's cancer there's respiratory
24:4X tract infections there's adverse
24:5X pregnancy and birth outcomes premature
24:5X death autism and ADHD dental caries poor
24:5X sleep cognitive dysfunction Alzheimer
25:0X disease erectile dysfunction and low testosterone
25:0X so there's said to be something for
25:0X everybody in here if not you your
25:0X children or your grandchildren so the
25:1X the first link between UV exposure and
25:1X lower risk of cancer was made by the
25:1X brothers cedric and frank garland who as
25:2X beginning graduate students at johns
25:2X hopkins school of public health and
25:2X knights en 74 saw a map something like
25:2X this it only had five color scales
25:3X instead of ten but they saw that there
25:3X was lower colon cancer in the southwest
25:3X in higher colon cancer in northeast they
25:3X just driven driven from Sandy Hill to
25:4X Maryland and then it was very sunny in
25:4X the southwest and not very sunny in the
25:4X Northeast so they hypothesized that
25:4X since the primary the
25:5X largest physiological effect of sunlight
25:5X is widen D production that bottom D must
25:5X reduce the risk of cancer well it took
26:0X them six years to get that paper
26:0X published and then it was an in a
26:0X British Journal which is finally finally
26:0X published in but nobody really took much
26:1X notice of it in 1985 they show that
26:1X dietary vitamin D was linked to low
26:1X cancer risk in 1989 they showed that low
26:2X serum 25 hydroxy vitamin is linked to
26:2X low colon cancer risk
26:2X they also extended this to breast cancer
26:2X and ovarian cancer somebody else did
26:3X prostate cancer and lymphoma but you can
26:3X understand that since no I was gonna get
26:3X rich selling vitamin D or selling
26:4X sunlight that the medical system had
26:4X just sort of said not much so I came
26:4X along in 1999 after doing some work
26:4X mentioned on on dietary factors and I
26:5X saw these new maps that were published
26:5X by the National Institutes of Health and
26:5X I saw all the read of the Northeast
27:0X except for prostate cancer was in the
27:0X northwest and I said gee maybe I can
27:0X explain this based on dietary factors
27:0X well I took two weeks to realize that we
27:1X eat the same food countrywide except in
27:1X the South would have Allah barbecue now
27:1X if you look at these you'll see very
27:1X similar patterns breast
27:1X again high mortality rates in the Northeast
27:2X but you have some also some high breast
27:2X cancer rates along the West Coast turns
27:2X out that along the coast you have more
27:2X clouds and fog and so people are not
27:3X getting as much UVB along the coast that
27:3X they were inland so breast cancer is not
27:3X quite as strong a link between UVB
27:3X Vaughn B and in reduced risk as colon
27:4X cancer for kidney cancer you'll see down
27:4X in Louisiana some hot spots that's
27:4X because of the chemicals in the chemical
27:5X manufacturing there stomach cancer you
27:5X sees a lot of red along the Mexican border
27:5X that's because of hygiene and much more
27:5X h pylori in among mexicans so we get
28:0X more stomach cancer prostate cancer is weird
28:0X you see the red now is shifted more to
28:0X the northwest and the blue more to the
28:1X southeast it turns out that both low and
28:1X high 25 hydroxy vitamin D have about the
28:1X equal risk for prostate cancer there's
28:2X some benefit of Von D in fighting
28:2X aggressive prostate cancer but it turns
28:2X out that that calcium is an important
28:3X risk factor for prostate cancer and
28:3X since one of the benefits of the effects
28:3X of vitamin D is to increase absorption
28:3X of calcium it could be that there's a
28:4X sort of a trade-off between having too
28:4X much vitamin D and inducing too much
28:4X calcium absorbtion that may play a role
28:5X here it's still being debated by the the
28:5X in the peer review literature I don't
28:5X have a definitive answer on that but so
28:5X what I did I got the NASA data for UVB
29:0X at the surface for July 1992 and you see
29:0X it's very asymmetrical the the highest
29:1X rates are in the southwest Arizona New
29:1X Mexico the lowest rates are northeast
29:1X and the reason you have higher UVB in
29:1X the west and an East is that the surface
29:1X elevation tends to be higher we have
29:2X more mountains and and even the arm like
29:2X the Nevada desert is higher than
29:2X then than a sea level and then you have
29:2X the westerly winds have to cross the
29:3X Rocky Mountains and in doing so they
29:3X pushed the tropopause higher and make
29:3X the stratospheric ozone layer thinner
29:3X and it's the ozone in the stratosphere
29:3X that blocks the UVB so you have less
29:4X absorption unless scattering in the
29:4X atmosphere so you have more UVB here in
29:4X the east you also have more clouds and
29:5X aerosols which is not reflected in this
29:5X map but but also plays a role so from
29:5X ecological studies we found about 15 to
30:0X 20 types of cancer that are reduced from
30:0X UVB exposure and we think and we have
30:1X evidence for a lot of these that higher
30:1X 25 hydroxy vine D levels are correlated
30:1X with lower cancer risk
30:1X so either incidence or mortality rates
30:2X so it's colon esophageal laryngeal oral
30:2X pharyngeal rectal small intestine the
30:2X female cancers breast in the material
30:3X ovarian and Evolver urogenital bladder
30:3X kidney prostate and testicular
30:3X miscellaneous organs gallbladder lung
30:3X pancreatic and thyroid and the blood
30:4X cancers lymphoma leukemia non-hodgkins lymphoma
30:4X now how much vitamin what's the
30:5X correlation between 25 hydroxy vitamin D
30:5X and cancer incidence well I made this is
30:5X sort of a graphical meta-analysis now
31:0X I've taken 11 studies from seven
31:0X countries and merge them together by
31:1X adjusting the the odds ratio with
31:1X respect to the 25 hydroxy Von D so
31:1X they're all laying the same line and now
31:2X the units here are Nana moles per liter
31:2X you divide by 2.5 to get nanograms per
31:2X milliliter so what you see is below
31:2X about 20 nanograms you get a steep rise
31:3X in the risk and when you get out to
31:3X about 40 nano grams you still have some
31:3X reduced risk but you're slowing down
31:4X the the the the increase the reduction
31:4X in odds ratio the the dash dash lines
31:5X and outside shield a 95% confidence
31:5X intervals there was this is the
31:5X uncertainty from the measurements
32:0X I mean sorry we have a this slope like
32:0X this and this seems to be typical for
32:0X other health outcomes as well although
32:0X for some diseases you may be a threshold
32:1X at twenty or thirty nanograms more than
32:1X forty or fifty nanograms like for cancer
32:1X and now we have results from this was a
32:2X recent clinical trial conducted into
32:2X Nebraska with postmenopausal women with
32:2X an average BMI of about 31 and a
32:3X baseline 25 hydroxy vitamin D of around
32:3X 33 nanograms
32:4X body mass index BMI so these were obese
32:4X people on average with high 25 hydroxy
32:4X but indeed there were about a I think
32:5X was a thousand women involved for four
32:5X years and they were given $2,000 per day
33:0X plus about a gram of calcium or placebo
33:0X or yeah or placebo and it turns out that
33:1X in the clinical trial in the
33:1X intention-to-treat they had one more
33:1X cancer case in the treatment arm then
33:1X then would be the case if they had less
33:2X than a one in 20 chance that this was a
33:2X an effect found by chance there was a P
33:2X was less P was 0.06 instead of 0.05 and
33:3X so when the papers published JAMA said
33:3X on news release saying clinical trial
33:3X shows that vitamin D does not
33:3X significantly reduce the risk of cancer
33:4X but the people at Creighton University
33:4X along with with people from grassroots
33:4X health and Keith beggarly said now wait
33:4X a minute if we look at the serum 2X 33:5X hydroxy of
33:5X the most the most recent measurement
33:5X before they developed cancer we find
33:5X that those that had between 40 and and
34:0X 80 nanograms per milliliter has
34:0X significantly reduced risk of cancer
34:0X compared to those with less than 4 -“
34:1X nanograms familiar but since they have
34:1X not specified this as an outcome in the
34:1X protocol JAMA made them put it in the
34:1X online appendix the supplementary files
34:2X which was not seen by most people
34:2X Creighton University however issued a
34:2X press release saying see we found a
34:2X benefit and so we had the two competing
34:3X press releases and that who have people
34:3X saw both were a little confused for
34:3X cardiovascular disease here's another
34:3X observational study meta-analysis
34:4X showing that below 20 nanograms per
34:4X milliliter there's an increased risk of
34:4X cardiovascular disease unfortunately
34:4X there have been no clinical trials that
34:5X have confirmed that giving people
34:5X vitamin D and reduce the risk of
34:5X cardiovascular disease so the question
34:5X is is this maybe because they are out of
35:0X doors more maybe they're exercising more
35:0X out of doors maybe they're eating
35:0X different diet or is there vitamin D
35:0X maybe it's a long-term vitamin D effect
35:1X and if you do a two to four year study
35:1X you don't find the effect so this is
35:1X still sort of up in the air about
35:1X cardiovascular disease seasonal
35:2X influenza dr. John Connell who runs the
35:2X vitamin D council proposed in 2006 that
35:2X influenza was largely seasonal due to
35:3X seasonal variations and UVB doses he had
35:3X been given being giving his he worked at
35:3X a task Adaro hospital for the clinically
35:3X insane he'd been giving his patients
35:4X 5000 IU per day and in 2004-2005 when an
35:4X influenza epidemic came through the area
35:4X his patients were largely spared so they
35:5X got him thinking about well maybe
35:5X vitamin D does reduce the risk of
35:5X influenza in fact shortly after his
35:5X papers published the results of a
36:0X clinical trial involving postmenopausal
36:0X women in Long Island was was reanalyzed
36:0X and they found that indeed those taking
36:0X $2,000 per day had very few influenza or
36:1X cold events whereas those taking 800 had
36:1X several and those taking 400 are you had
36:1X quite a few so that was one clinical
36:1X trial that that showed that yes finally
36:2X done reduce did reduce the risk of
36:2X influenza and then a one involving
36:2X Japanese school children show that it
36:2X reduced type a but not type B influenza
36:2X I might add that cold temperature and
36:3X low humidity also in contribute to the
36:3X seasonality because the influenza virus
36:3X lives better in a cold dry environment
36:4X so that's why it can be passed from
36:4X person to person in the winter but on
36:4X the other hand it's the volunteers can
36:4X help you induce Catholic sidon to fight
36:4X the influenza pregnancy clinical trials
36:5X in South Carolina found that pregnant
36:5X women have better pregnancy and birth
36:5X outcomes by taking 4060 400 IU per day
36:5X of 1 D 3 and reaching 40 nanograms per
37:0X milliliter 25 for dr. c ymd the reason
37:0X is that above 40 nanograms
37:0X the 125 dihydroxy of vitamin D
37:1X concentration is stabilized
37:1X leaving to improve gene expression and
37:1X there's ever a period of life when gene
37:1X expressions important is during the
37:2X fetal development period so the benefits
37:2X of IMD during pregnancy includes reduced
37:2X risk of primary c-section delivery on
37:2X c-section delivery
37:2X well vaginal delivery is important to
37:3X give the the infant the the gut biome it
37:3X needs to to get off to healthy immune
37:3X start reduced risk of gestational
37:3X diabetes reduce risk of preterm birth
37:4X and for the infants reduced risk of low
37:4X for gestational weight reduced risk of
37:4X autism and reduced risk of asthma this
37:5X is from the studies in South Carolina
37:5X and it's showing that below below twenty
37:5X six point five nanograms per milliliter
37:5X there's a reduction in the gestational
38:0X age above that there seems to be a
38:0X plateau so here's another benchmark for
38:0X pregnant women in terms of overall age
38:1X adjusted mortality rate standard Garlin
38:1X and company advertised
38:1X analyzed 32 observational studies and
38:2X found that it took 36 nanograms per
38:2X milliliter before the mortality rates
38:3X plateaued and you see there's a pretty
38:3X much a linear rise to twice the
38:3X mortality rate at lower local of 1 -?
38:4X nanograms familiar as adult mortality so
38:4X I've done my own analysis where I looked
38:5X at disease rates in in various countries
38:5X and the observational studies for the
38:5X relationship between 25 hydroxy body and
39:0X the incidence or mortality rate and
39:0X found that if everyone well the global
39:0X average 25 hydroxy varney is around 2 -?
39:1X nanograms it turns out because of skin
39:1X pigmentation varying no matter whether
39:1X you where you live the population
39:1X average is around 22 nanograms unless
39:1X you're in the Middle Eastern country and
39:2X where to any close then it's gonna be
39:2X lower if you're african-american it's
39:2X gonna be lower and so on but anyway if
39:2X you increase from 22 to 44 nanograms it
39:3X appears that the vitamin d sensitive
39:3X mortality rate would reduce by about 2 -? percent
39:3X and that's accounts for about half of a
39:3X and the deaths and so this would lead to
39:4X a life expectancy increase in about two years
39:4X athletic performance again John Cornell
39:4X wrote a paper I think into 2009 and he
39:5X went through a number of reasons why he
39:5X thought that there'd be better athletic
39:5X performance for one thing he point out
39:5X that the Mexican Olympics 1968 had a lot
40:0X of World Records and a lot of people had
40:0X gone there to to practice before had to
40:0X get used to the altitude he thought it
40:0X was not the altitude but the UVB and the
40:1X vitamin D so he published this 2009 in a
40:1X sports medicine journal and as a result
40:1X the Chicago Blackhawks became the first
40:2X vitamin team in modern professional
40:2X sports became the first time the team in
40:2X modern professional sports history and
40:2X according to John sources the Black Hawk
40:3X team physician became began diagnosing and treating
40:3X finding efficiency in all blackhawk
40:3X players about 18 months ago written in
40:3X 2010 and apparently most players were
40:4X taking 5,000 IU per day after losing
40:4X many seasons last year the Blackhawks
40:4X came out of nowhere to get the Western
40:4X Conference Finals
40:4X this year they're playing even better so
40:5X one thing is going to do is reduce their
40:5X risk of influenza and Kohl's and all
40:5X sorts of other respiratory infections
40:5X the other thing is going to do is reduce
40:5X the risk of stress fractures another
41:0X thing a faster healing of wounds so very
41:0X important
41:0X Don and I to John also wrote the first
41:1X paper on vitamin D and the risk of
41:1X autism I worked with him in 2013 we got
41:1X the Provost data for children ages 6 to
41:2X 17 years as a function of state I looked
41:2X at those versus UVB doses in the summer
41:2X for the well actually of October and
41:2X found that there was an inverse
41:3X correlation between UVB and risk of
41:3X autism it turns out that African
41:3X Americans have higher rates of autism
41:3X than white Americans their darker skin
41:4X making less vitamin D and there are
41:4X mechanisms to explain why find D
41:4X deficiency in both in in in utero and
41:5X early life would lead to increased risk
41:5X of autism ADHD it has a pattern which
42:0X you see the lower rates in the Southwest
42:0X higher rates in the east and northeast
42:0X again as sort of looks like the UVB
42:1X inverse of UVB dental carries it turns
42:1X out that there were data from the 20s
42:1X 30s and 40s if I plotted the the the
42:2X dental health rank versus UVB dose you
42:2X see that below about 6.5 kilojoules per
42:3X meter squared there was a linear slope
42:3X upwards and above that there was a
42:3X plateau in fact even a paper from 186 -?
42:3X showed that if you looked at the Union
42:4X Army soldiers those from Maine and New
42:4X Hampshire had lost quite a few teeth
42:4X why time you got to Kentucky or so they
42:4X had most of T still intact so even then
42:5X there was an effect of UV on dental health
42:5X in fact the first clinical trial on
42:5X vitamin D was for children in England in
43:0X 1928 giving them body and looking at
43:0X dental caries and they found that yes
43:0X they reduce the risk of dental caries
43:0X and the woman doing this study said that
43:1X the bacteria were dead
43:1X she didn't know why but we know why now
43:1X and this here shows that that there were
43:1X a number of studies never clinical
43:2X trials in the 30s and 40s
43:2X we showed a 50% reduction in dental
43:2X caries for children taking a vitamin
43:2X game sleep turns out that raising 2 -?
43:3X hydroxido into 60 to 70 grams per
43:3X milliliter does improve sleep however
43:3X the women doctor gummy enact doing this
43:3X study found that after two years the
43:4X people who started reporting systemic
43:4X pain one of her patients helped her
43:4X realize that it was because they were
43:5X becoming a vitamin D vitamin B deficient
43:5X the back gut bacteria producing finally
43:5X when you sleep you restore the body
43:5X through methylation and methylation
43:5X requires B vitamins and so they're using
44:0X up some of the vitamins in the gut and
44:0X when she gave them be 104 which has the
44:0X multiple beef in a couple months they
44:0X got the gut back in shape and pain went
44:1X away and they were fine there's also
44:1X fine the verbal fluency cognitive decline
44:1X there's Alzheimer's disease and dementia
44:2X this looks like below 20 nanograms
44:2X there's a problem erectile dysfunction
44:2X below 20 nanograms per milliliter
44:3X testosterone there's a study involving
44:3X obese people in Austria and they found
44:3X that by giving them vitamin D they did
44:3X increase their testosterone in fact I've
44:4X myself and two other men taking high
44:4X doses of vitamin D found that when they
44:4X were up around 60 or 70 nanograms per
44:4X milliliter that they got the
44:4X testosterone up so it's a in fact that
44:5X could help improve athletic performance
44:5X because testosterone helps muscles
44:5X surgery turns out that people who go
45:0X into surgery with higher 25 hydroxy
45:0X Vandy recover more quickly
45:0X wounds heal faster burns heal faster so
45:1X whereas widened D policy headed well we
45:1X have four or five or six major one D
45:1X supplementation trials which will
45:2X complete data collection this year next
45:2X year and then analyze the results they
45:2X generally use about 2000 IU per day or
45:3X $100,000 per month and these studies as
45:3X imperfect as they are will provide the
45:3X basis for the next recommendations I was
45:4X just in Warsaw this is a committee
45:4X reviewing posters by the mrs. Michael
45:4X Holick in front looking carefully at
45:4X that posters so I published a paper
45:5X recently saying why the clinical trial
45:5X should be based on vitamin D on 2 -?
45:5X hydroxy Von D because most the trials
46:0X are based on the assumptions used for
46:0X pharmaceutical drugs first of all that
46:0X the trial is a sole source of the agent
46:1X and second that there's a linear
46:1X dose-response relationship between the
46:1X agent and the health outcome
46:1X neither assumption is valid for vitamin
46:2X for vitamin D and also it turns out many
46:2X of the trials do not follow to measure
46:2X 25 hydroxy vitamin D they just you know
46:3X think you take the average healthy
46:3X person and so they get a healthy person
46:3X affect that there's no benefit of more
46:3X vitamin D here we show that from the
46:4X grassroots health data set that for
46:4X people taking any reporting that they're
46:4X taking any value of oral vitamin D that
46:5X there's about a 50 nanogram spread plus
46:5X or minus 15 intagram of the 25 hydroxy
46:5X vitamin D concentration that's why if
46:5X you really wanna know what your vitamin
47:0X E level is you gotta have it measured it
47:0X turns out that why do we need clinical
47:0X trials well observational studies could be
47:1X being using the 25 hydroxy of any
47:1X concentration as an indent of diet or of
47:1X UVB exposure it turns out for example
47:2X that meat consumption increases
47:2X literally from the from the tropics
47:2X highest consumption racer and the high
47:2X latitudes if you have mechanisms you
47:3X don't know how much how important Von D
47:3X is in reducing risk the health systems
47:3X most of clinical trials as a gold
47:3X standard we're now in the evidence-based
47:3X medicine
47:3X era as imperfect as it is but they're
47:4X trying in Budapest there's a lot of meat
47:4X being sold and so they get to increase
47:4X the risk of cancer and alt and
47:5X Alzheimer's disease but they're getting
47:5X some vitamin D so it's a bit of a
47:5X trade-off so anyway we're proposing that
47:5X all these trials be based on 25 hydroxy
48:0X Von D including the imaging beforehand
48:0X choosing the participants give enough
48:0X item D to raise 5 D levels high
48:0X measuring ans cetera et cetera
48:1X now why you've never heard about the
48:1X whole truth about vitamin D this is from
48:1X natural news.com well there's the
48:1X Federal Trade Commission that tells
48:2X tanning companies they cannot advertise
48:2X that tanning produces vitamin D big
48:2X pharma see is that as competition komen
48:3X Race for the Cure they don't want to
48:3X cure there they don't want to prevent
48:3X breast cancer they want to manage for
48:3X breast cancer the FDA they help sponsor
48:3X the Institute of Medicine report there's
48:4X oncologists who make fifty thousand
48:4X hundred thousand dollars in treating
48:4X cancer ten dollars a year for vitamin E
48:4X to prevent cancer no you don't want that
48:5X and the National Cancer Institute
48:5X so grassroots well okay I'm a co-author
48:5X on a book coming out shortly called
49:0X embrace the Sun mark Sorenson is the
49:0X primary author and dr. T who spoken here
49:0X before is doing a very careful text
49:0X editing Michael Holick wrote the
49:1X foreword for this this should be
49:1X available in November or December and
49:1X you can contact me and we can tell you
49:1X how to get it now for more information go to
49:2X med which has 27 million health
49:2X publications listed there you can
49:3X finally access with scholar.google.com
49:4X who spends all his waking hours making
49:4X bundy information accessible finding
49:4X counsel in nevada new society a society in cancer
49:5X thank you okay great thank you it's
49:5X really refreshing to hear someone talk
49:5X about being in the sun is it really good for you
50:0X we're gonna push a little bit beyond
50:0X where we would normally try to stop i
50:0X want to take a couple of questions if we
50:0X have them and then we need to start then
50:1X we can continue yeah after the
50:1X informally so any question i'm for the
50:1X group here right doesn't heal per day
50:2X but what are the consequences well the
50:2X primary consequence of too much of
50:2X vitamin D is hypercalcemia if you get
50:3X hypercalcemia you don't feel good and so
50:3X these people are taking fifty thousand
50:3X definitely feel fine they do have very
50:4X high 25 hydroxy Von D concentrations I
50:4X guess we'll just have to see what happens
50:4X it stores though the same 50,000 a year
50:5X saying but if you took it yeah if you
50:5X took it once a week or hmm
50:5X yeah the vitamin E can store in the fat
51:0X and the muscles the 25 has a short
51:0X half-life I'm hoping you would ask a
51:0X question first of all thank you for your
51:1X contributions to the scientific
51:1X community second of all so I have my
51:1X understanding is UVB is the best from 1 -?
51:1X a.m. to 4 p.m. and what would you
51:2X recommend like 20 to 25 minutes in the
51:2X sunlight well more like 10 to – ?
51:2X and it depends on how much skin you can
51:3X expose and your skin pigmentation so if
51:3X you're fair-skinned and mixed pros let's
51:3X say a young person exposing 10% of his
51:4X body can maybe make after you 20 or 30 I
51:4X you per per minute maybe so maybe 25 to
51:4X 15 minutes for a young person it might
51:5X be enough but if you can expose a
51:5X quarter of your body that's better you
51:5X cut down the time there are there are
51:5X UVB meters out that tell you how much
52:0X time you has been made thank you I'll
52:0X check that out okay one more quick okay
52:0X so that's Daly but if you only get out
52:1X once a week but you're out for six to
52:1X ten hours and the half-life is long
52:1X enough you can get enough that way also
52:1X correct yeah you can make twenty
52:2X thousand in a day so and you can store
52:2X the X and the half-life is two and a
52:2X half weeks and you can store the excess
52:2X vitamin D so that would probably do okay
52:3X that's good do you mind go ahead and ask
52:3X your question one on one or the one
52:4X where the people are taking and then
52:4X they're measuring the dosages about four
52:4X from the end or so is that published
52:4X somewhere that seems like a really
52:5X important okay we'll go ahead why don't
53:0X you go ahead and finish this one yeah
53:0X let's complete the evening thank you all
53:0X for coming we meet the third Thursday of
53:1X every month you
