WEBVTT
00:00:00.000 --> 00:00:06.280
Well welcome to this month's Ask Your Ob Doctor. My name is Andrew Murray. From 7 till 8pm
00:00:06.280 --> 00:00:12.280
this is a live show. We have callers calling in from 7.30 to 8pm to ask questions about
00:00:12.280 --> 00:00:16.860
the topic that we are going to go through. This month's topic is going to be a round
00:00:16.860 --> 00:00:25.280
up of the point that we left off in March discussing progesterone and estrogen. And
00:00:25.280 --> 00:00:31.840
this month I want to dissect that a little more with some of the facts and some of the
00:00:31.840 --> 00:00:39.240
arguments against and in fact plain refuting of those "facts" about how positive estrogen
00:00:39.240 --> 00:00:46.920
was and how negative progesterone was in a paper that was written by Inger Sundström
00:00:46.920 --> 00:00:52.120
Promona at the University of Uppsala in Sweden, apparently one of the leading experts on brain
00:00:52.120 --> 00:01:00.560
metabolism and sex hormones. I mentioned in March that the PROTECT and SYNAPSE which are
00:01:00.560 --> 00:01:06.720
acronyms, PROTECT and SYNAPSE trials of progesterone's anti-inflammatory effects used in the treatment
00:01:06.720 --> 00:01:14.000
of traumatic brain injury were published and reviewed and apparently were relatively unsuccessful.
00:01:14.000 --> 00:01:23.520
Now Dr. Stein, a 30 year PhD brain injury expert at Emory University was part of the
00:01:23.520 --> 00:01:29.480
team which published the paper in the Journal of Neurotrauma and he outlined some very obvious
00:01:29.480 --> 00:01:36.420
mistakes in the studies and basically said that the criteria with which the study was
00:01:36.420 --> 00:01:43.400
done did not produce valid results and he was strongly opposed to the findings which
00:01:43.400 --> 00:01:50.440
showed there was no positive benefit for progesterone citing some very good facts and evidence to
00:01:50.440 --> 00:02:00.620
the contrary. So in terms of the ongoing lies if you like about how positive estrogen is
00:02:00.620 --> 00:02:07.520
for you and/or how dangerous progesterone is for you, we have had for many years now
00:02:07.520 --> 00:02:14.320
Dr. Raymond Peat joining us to discuss his findings and cover a lot of evidence that
00:02:14.320 --> 00:02:20.240
he has unearthed himself and I am very pleased to have him on the show. So I wanted just
00:02:20.240 --> 00:02:24.840
to quickly welcome Dr. Peat and then give people a little more information about how
00:02:24.840 --> 00:02:30.720
to contact the studio for call-ins from 7.30 on. So Dr. Peat are you with us? Yes I am
00:02:30.720 --> 00:02:36.120
here. Ok thanks so much for joining us. For people that are in the area there is a 707
00:02:36.120 --> 00:02:43.720
number which is 707 923 3911 and I wanted to quickly ask, I just noticed as I came into
00:02:43.720 --> 00:02:48.960
the studio that the 800 numbers have been scratched out. I was just about to correct
00:02:48.960 --> 00:02:52.320
you in case you started saying that. Yeah apparently there is a problem with the 800
00:02:52.320 --> 00:02:58.480
numbers so anybody can call from anywhere. The country code is 01 I believe. Yeah because
00:02:58.480 --> 00:03:04.360
we have people from Finland, we have people from Australia and other places in the world.
00:03:04.360 --> 00:03:15.520
So ok yeah 707 923 3911. So I also wanted just to point out that after business hours
00:03:15.520 --> 00:03:21.440
or during business hours rather 9 to 5 Monday through Friday people can either call in and
00:03:21.440 --> 00:03:30.960
either or write to me at my address Andrew@westernbotanicalmedicine.com or call if they have any questions or if
00:03:30.960 --> 00:03:37.120
they want to follow up any consultations, nutritional consultations or related subjects
00:03:37.120 --> 00:03:41.760
around health and the things that we are purporting to be things that are very beneficial for
00:03:41.760 --> 00:03:47.200
you which you won't normally hear in the mainstream. Dr. Peat has been a big advocate of things
00:03:47.200 --> 00:03:52.720
like thyroid and sugar and progesterone and the mainstream medicine and science would
00:03:52.720 --> 00:03:58.760
argue that sugar is not good for you or that pregnenolone or progesterone for example are
00:03:58.760 --> 00:04:03.920
not good for you when there is plenty of evidence to show that there is. I think this is probably
00:04:03.920 --> 00:04:10.880
never so clear as in the trials of HRT and some of the withdrawing of those HRT programs
00:04:10.880 --> 00:04:18.920
and hormone replacement therapy up quote unquote that women with estrogen dominance is probably
00:04:18.920 --> 00:04:23.040
the last thing that they want is estrogen replacement but yet the industry and doctors
00:04:23.040 --> 00:04:31.680
still continue to say that the bone health benefits of estrogen are to be advised and
00:04:31.680 --> 00:04:37.480
that women with hot flashes and other mood disorders that estrogen is a lacking substance
00:04:37.480 --> 00:04:42.240
that they actually need and will help them. So during the course of the next hour and
00:04:42.240 --> 00:04:48.720
30 minutes or so I am going to be discussing some of the arguments for progesterone and
00:04:48.720 --> 00:04:54.880
the arguments against estrogen and Dr. Peat with his background is probably never so qualified
00:04:54.880 --> 00:05:00.600
to speak on the subject given that his PhD was in reproductive hormones. So Dr. Peat
00:05:00.600 --> 00:05:04.640
would you just give an outline of your professional and academic background so people that are
00:05:04.640 --> 00:05:12.880
listening can hear where you have come from? Before I studied biology I was a literature,
00:05:12.880 --> 00:05:25.720
linguistics and art major and teacher and I decided to study biology initially to get
00:05:25.720 --> 00:05:33.400
more understanding of how language and intelligence and consciousness work and what I found was
00:05:33.400 --> 00:05:42.200
that brain biology, cognitive science so called was pure dogmatism, very little science in
00:05:42.200 --> 00:05:50.040
it so I shifted over to reproductive physiology to basically study how the organism works
00:05:50.040 --> 00:05:59.120
all the way from the germ cell to the brain and the brain science really is not distinct
00:05:59.120 --> 00:06:11.520
from reproductive physiology. The brain is really the motor for the whole life process
00:06:11.520 --> 00:06:26.640
and I did my dissertation in 1972 on the oxidative changes in the uterus in particular as it
00:06:26.640 --> 00:06:32.280
changes with aging. Okay good so I guess let's just jump straight
00:06:32.280 --> 00:06:40.120
into some of the questions that I had that we got left off from March and these are basic
00:06:40.120 --> 00:06:47.000
inquiries into the mechanism by which estrogen has its negative effects and then we'll get
00:06:47.000 --> 00:06:54.400
into an article that was written by Inger Sundström who is a professor at the University
00:06:54.400 --> 00:06:59.600
of Uppsala and an apparent leading expert on brain metabolism and sex hormones who said
00:06:59.600 --> 00:07:07.160
some very strange things that I'd like you just to hear and give your take on it.
00:07:07.160 --> 00:07:14.120
Susceptible epilepsy and the estrogens like estrone, estriol and estradiol how do you
00:07:14.120 --> 00:07:19.800
understand the triggering of the epilepsy in these certain susceptible females? It's
00:07:19.800 --> 00:07:25.240
estrogen related isn't it? Yeah in my research I looked through everything
00:07:25.240 --> 00:07:32.960
that had been done on physiology especially as it relates to the brain and uterus up until
00:07:32.960 --> 00:07:43.080
1970 and I couldn't find any evidence that would clearly distinguish the physiology of
00:07:43.080 --> 00:07:53.400
estrogen stimulation from x-ray stimulation or oxygen deprivation or vitamin E deficiency
00:07:53.400 --> 00:08:02.080
which interferes with oxygen use. All of those things deplete the energy production of the
00:08:02.080 --> 00:08:15.160
cell which is based on oxidation and when the brain is oversupplied with estrogen or
00:08:15.160 --> 00:08:23.080
lacks its antagonist especially progesterone the whole system but everything in the brain
00:08:23.080 --> 00:08:32.800
included wastes oxygen and is unable to keep the energy level up to the point that the
00:08:32.800 --> 00:08:43.400
cells are stable and one of the strange things that has been overlooked or seen upside down
00:08:43.400 --> 00:08:52.240
in both biology and medicine for most of the century is that high energy state of a cell
00:08:52.240 --> 00:09:00.680
is the state in which it's ready to work and function but it is not acting all the time
00:09:00.680 --> 00:09:08.920
it's sitting there ready to work and when it is forced to work more than it is ready
00:09:08.920 --> 00:09:19.520
for the energy level falls and it gets into a state trying to restore the energy but it
00:09:19.520 --> 00:09:30.960
is in a constantly active state. If you cause hypoglycemia by interfering with the liver
00:09:30.960 --> 00:09:40.120
for example it works the same as a lack of oxygen and estrogen happens to interfere with
00:09:40.120 --> 00:09:47.640
the supply of glucose to cells. It activates insulin but it also activates the release
00:09:47.640 --> 00:09:56.480
of fatty acids from the tissues and the fatty acids block the ability to oxidize glucose
00:09:56.480 --> 00:10:07.480
so estrogen does. It activates the cells by increasing the function of glutamic acid,
00:10:07.480 --> 00:10:20.600
a brain excitant and in increasing glutamate it decreases GABA the inhibiting signal. GABA
00:10:20.600 --> 00:10:31.240
should be produced by the breakdown of glutamic acid so estrogen is exciting the brain cells
00:10:31.240 --> 00:10:38.240
and at the same time interfering with their use of oxygen and glucose.
00:10:38.240 --> 00:10:45.120
Estrogen and the estrogens, estro and estrolysis, etc. these really mimic a kind of stress response
00:10:45.120 --> 00:10:46.120
then?
00:10:46.120 --> 00:10:56.560
Yes, I consider estrogen's function to be the controlled stress. The whole organism
00:10:56.560 --> 00:11:08.280
is moving through a developmental process and it requires a constant supply of energy
00:11:08.280 --> 00:11:18.040
and if that energy supply becomes fatally impaired then the function of estrogen in
00:11:18.040 --> 00:11:29.040
the reproductive system is to erase the whole scheme that was producing the organism's
00:11:29.040 --> 00:11:37.280
development through its life process. Suddenly the excess of estrogen as a stress signal
00:11:37.280 --> 00:11:52.080
erases the whole program and reverts to the single multiplying cell. So without anything
00:11:52.080 --> 00:12:01.680
interfering estrogen tends to produce the cancer cell but it also activates the production
00:12:01.680 --> 00:12:09.920
of the egg and the readiness of the egg to start a new organism. So its proper function
00:12:09.920 --> 00:12:20.560
should be once a month for a few hours to activate the potential new life and that only
00:12:20.560 --> 00:12:34.520
starts at puberty. Up until puberty the brain is metabolizing at a very high rate and the
00:12:34.520 --> 00:12:43.120
catamenial epilepsy tends to begin around the age of nine when estrogen is rising and
00:12:43.120 --> 00:12:54.120
progesterone hasn't risen yet. The brain metabolism slows down at puberty so the body
00:12:54.120 --> 00:13:01.440
takes it as a threat to survival and so it turns on the reproductive process.
00:13:01.440 --> 00:13:06.320
I just wanted to kind of recount that you said that and I think I've understood this
00:13:06.320 --> 00:13:12.200
in the correct way that estrogen, the only real benefit for estrogen then is the inflammation
00:13:12.200 --> 00:13:18.120
it provides or promotes to stimulate implantation of a new site in the endometrium in terms
00:13:18.120 --> 00:13:23.120
of successful pregnancies. Is that correct? And then outside of that it doesn't really
00:13:23.120 --> 00:13:29.960
have too much benefit. Yeah, throughout the organism whenever the
00:13:29.960 --> 00:13:36.600
tissue is stressed it tends to turn on locally the production of estrogen. That's how it
00:13:36.600 --> 00:13:44.040
so easily leads to cancer because every tissue has the apparatus for making estrogen.
00:13:44.040 --> 00:13:47.400
Right, you said every cell in the body can secrete it essentially.
00:13:47.400 --> 00:13:54.440
Yeah, and after menopause when the production of progesterone becomes very limited there
00:13:54.440 --> 00:14:00.840
is a tendency for all of the body's tissues to begin making estrogen. So it's just the
00:14:00.840 --> 00:14:09.600
opposite of what the menopause doctors have been teaching. When progesterone disappears
00:14:09.600 --> 00:14:16.760
the breast, the uterus, the brain, the liver, the skin, the fat, muscles even begin producing
00:14:16.760 --> 00:14:24.320
estrogen, but it can't escape from the cell because it also increases the estrogen binding
00:14:24.320 --> 00:14:34.480
protein, the estrogen so-called receptor. And in the absence of progesterone the intracellular
00:14:34.480 --> 00:14:40.560
estrogen increases but it doesn't get into the blood so you measure the blood and it
00:14:40.560 --> 00:14:44.440
looks like you're estrogen deficient. Interesting, it doesn't get into the blood,
00:14:44.440 --> 00:14:47.040
huh? Yeah, exactly when you're being systemically
00:14:47.040 --> 00:14:51.560
poisoned with intracellular estrogen. And as you've mentioned before on previous
00:14:51.560 --> 00:14:58.200
shows estrogen is very responsible for edema, cell swelling and that inefficiency that comes
00:14:58.200 --> 00:15:01.400
with that water logging from an energy point of view.
00:15:01.400 --> 00:15:08.920
The individual cell swells up when it's being excited and de-energized. When you can get
00:15:08.920 --> 00:15:16.480
the energy back up that squeezes the water out and that same swollen state occurs in
00:15:16.480 --> 00:15:24.000
capillaries and blood vessels and even though they get thicker they become leaky. Water
00:15:24.000 --> 00:15:30.480
goes through them into the tissues and out of your bloodstream and that's involved in
00:15:30.480 --> 00:15:38.000
the circulatory problems of pregnancy. The blood volume can't be maintained while the
00:15:38.000 --> 00:15:44.160
legs and feet tend to swell up and the kidneys sense the lack of circulation because the
00:15:44.160 --> 00:15:50.000
blood volume has shrunk and so the kidneys send out signals to raise the blood pressure
00:15:50.000 --> 00:15:58.200
to try to get more circulation. Interesting, and then lastly just wanted to
00:15:58.200 --> 00:16:04.560
recap what you said about that depolarized and repolarized state of the cell. So you
00:16:04.560 --> 00:16:12.480
mentioned that when a cell is in a ready state to perform work that relaxed state is what
00:16:12.480 --> 00:16:18.320
is so important for that proper contraction, that proper action potential to occur to do
00:16:18.320 --> 00:16:25.840
work and that in hypothyroidism the cell remains in a constantly stressed state where it's
00:16:25.840 --> 00:16:31.280
not able to relax and it's that very lack of relaxation that causes the energy problems.
00:16:31.280 --> 00:16:37.200
You can see exactly the same process in the heart muscle as in the brain and other cells
00:16:37.200 --> 00:16:44.760
but it's very easy to study in the brain and in the muscle because the muscle is such a
00:16:44.760 --> 00:16:55.760
concentrated muscle system and estrogen weakens but makes more frequent the contraction and
00:16:55.760 --> 00:17:05.040
it's a great excess of estrogen causes a shock like state of the heart, rapid but very, very
00:17:05.040 --> 00:17:13.920
weak pulsation where progesterone strengthens, it lets the cells build up energy so that
00:17:13.920 --> 00:17:19.400
when it does contract it's a very powerful contraction and pumps very efficiently.
00:17:19.400 --> 00:17:24.480
Okay, good. Well I never like to turn people away and I know you do this because you like
00:17:24.480 --> 00:17:30.840
the interaction with people asking questions that you've no preparation for if you like,
00:17:30.840 --> 00:17:35.160
you've not been prepared so there's a caller on the line who I think wants to ask a question
00:17:35.160 --> 00:17:38.760
so let's take this caller, a call away from and what's your question?
00:17:38.760 --> 00:17:44.440
Yes, hi my name is Shana from Hesperia. Hey Hannah, welcome to the show. What's your
00:17:44.440 --> 00:17:49.360
question? Yes, my question is regarding chronic fatigue
00:17:49.360 --> 00:17:58.840
syndrome. Can Dr. Ray Peat elaborate on what this is and what is the underlying condition
00:17:58.840 --> 00:18:06.960
is it hypometabolism or what and then my second question is low dose naltrexone, is it effective
00:18:06.960 --> 00:18:10.280
for CFS? Okay, I think there's a lot of break up on
00:18:10.280 --> 00:18:14.040
the line but I think that first question was related to chronic fatigue syndrome, what
00:18:14.040 --> 00:18:19.360
do you see, your ideas on chronic fatigue syndrome, how do you see it and then also
00:18:19.360 --> 00:18:23.040
naltrexone I think was... Low dose.
00:18:23.040 --> 00:18:28.400
Low dose naltrexone, LDN. Okay, Dr. Peat, what do you think of chronic fatigue syndrome
00:18:28.400 --> 00:18:33.200
as a... One way of thinking of it is that it's very
00:18:33.200 --> 00:18:40.640
similar to in the brain the seizure state or in the heart the failure state under the
00:18:40.640 --> 00:18:50.840
influence of a lack of progesterone and excess of estrogen or simply such a deficiency of
00:18:50.840 --> 00:18:59.640
energy that the cell goes into that swollen over excitable state. When a cell is in very
00:18:59.640 --> 00:19:10.040
bad condition, as far as I know every cell in the body can also produce histamine as
00:19:10.040 --> 00:19:17.200
it's getting very desperate, not only in a chronic sort of desperation cells produce
00:19:17.200 --> 00:19:25.120
estrogen but in a most acute situation they produce histamine and in the hypothyroid,
00:19:25.120 --> 00:19:33.680
low progesterone chronic state the body tends to locally produce a lot of histamine and
00:19:33.680 --> 00:19:38.760
other inflammatory things. Okay, and what do you think about naltrexone,
00:19:38.760 --> 00:19:47.160
low dose naltrexone, does that have any merit? In my experience using naloxone more than
00:19:47.160 --> 00:19:54.280
naltrexone but they're essentially identical, one is a little more oil soluble, I found
00:19:54.280 --> 00:20:06.520
that from one to four milligrams per day of naloxone would break a depressed condition
00:20:06.520 --> 00:20:17.120
by suppressing the endorphins which are induced by lactic acid and fatigue. The endorphins
00:20:17.120 --> 00:20:27.680
are another emergency measure to turn off the excitation but with a very small dose
00:20:27.680 --> 00:20:36.360
some people use even a hundredth of a milligram and find a very therapeutic effect so I consider
00:20:36.360 --> 00:20:44.920
four milligrams a day a fairly big, larger than necessary dose.
00:20:44.920 --> 00:20:48.880
Okay good, so let me just quickly ask, I think we have another caller on the line, okay well
00:20:48.880 --> 00:20:52.080
let's take this next caller and see where we're going, caller you're on the end, what's
00:20:52.080 --> 00:21:00.160
your question? Hi, I have a question about the B complex vitamins, I've been listening
00:21:00.160 --> 00:21:07.240
for a while so I understand B1, B2 and B3 and why they're beneficial, I wanted to go
00:21:07.240 --> 00:21:14.360
backwards so B9 is I guess folic acid and B7 is biotin and I think in some of the stuff
00:21:14.360 --> 00:21:21.280
I read about what people seem to be interpreting regarding your research or point of view is
00:21:21.280 --> 00:21:34.880
that 1, 2 and 3 are important and 6 in a smaller amount but B5, anaphenic acid, B4, adenosine
00:21:34.880 --> 00:21:42.360
and folic acid and B12 are probably not to be taken and so I'm probably not giving the
00:21:42.360 --> 00:21:45.600
full story so I just wanted to say that's sort of the question, are these the bad guys
00:21:45.600 --> 00:21:52.040
and if so why? Because when someone gets a B complex vitamin they actually have specific
00:21:52.040 --> 00:21:59.280
ratios of all these in many cases and I'm just wondering are they properly named B vitamins
00:21:59.280 --> 00:22:05.720
and or should they be taken and thought of separately as opposed to particular ratios
00:22:05.720 --> 00:22:10.920
between each one of them to have the proper effect systemically? Dr. Peat I know you're an
00:22:10.920 --> 00:22:18.320
advocate of liver for that reason but how would you define the B vitamins in terms of
00:22:18.320 --> 00:22:28.720
necessity and the sources of? Their main metabolic similarity is that they are regulators and
00:22:28.720 --> 00:22:40.160
facilitators of cell oxidative energy processes. Panthenic acid is somewhat off the main group
00:22:40.160 --> 00:22:54.640
but it's very essential. It's anti-stress, helps with regulating blood sugar and allergies.
00:22:54.640 --> 00:23:04.440
Sometimes 400 to 500 mg dose of panthenic acid can relieve stress symptoms and it's
00:23:04.440 --> 00:23:12.240
unusual in that it doesn't affect the interactions of the others. It's sort of on a side line
00:23:12.240 --> 00:23:20.360
where it can be taken in monkeys, they fed them a cup a day of pure panthenic acid with
00:23:20.360 --> 00:23:26.560
no side effects. If you did that with any of the other B vitamins you would quickly
00:23:26.560 --> 00:23:36.360
reach a toxic effect. Panthenic acid can be taken daily because all these are water soluble
00:23:36.360 --> 00:23:42.280
but this can be taken daily up to 400 mg and you will see some benefit of cellular oxidative
00:23:42.280 --> 00:23:48.000
energy. I'm thinking more about digestion too because some of these, like I've taken
00:23:48.000 --> 00:23:56.320
B1 and B2 recently and I really believe it's helped my ability to digest things. I'm a
00:23:56.320 --> 00:24:03.280
young man of around 60 so I'm just wondering how to take these, how much to take and how
00:24:03.280 --> 00:24:10.080
often as opposed to what's being out there in the research because it seems to not be
00:24:10.080 --> 00:24:17.280
accurate relative to what you're saying. The orthomolecular movement 40 years ago I think
00:24:17.280 --> 00:24:25.400
encouraged a lot of overdose excess use of them. You can get extremely therapeutic results
00:24:25.400 --> 00:24:36.520
sometimes with 5 or 10 times the minimum daily requirement like 10 or 20 mg of B1, 10 mg
00:24:36.520 --> 00:24:51.040
of B2, 10 mg of B6 and so on. Sometimes larger doses are effective but I think it's good
00:24:51.040 --> 00:24:55.480
to try the smallest dose, maybe 5 times the minimum daily requirement.
00:24:55.480 --> 00:25:01.280
Okay, so it's okay to take that daily. So for the ones you mentioned, about 10 to 20
00:25:01.280 --> 00:25:08.040
mg in a day is okay and I guess B3 is a little different in the sense you could take 400
00:25:08.040 --> 00:25:15.120
to 500 of that one too, right? It's not just B5 but B3 also, am I right?
00:25:15.120 --> 00:25:16.120
Niacin.
00:25:16.120 --> 00:25:17.120
Niacinamide.
00:25:17.120 --> 00:25:28.160
Yeah, it's important to get the amide form. The other releases, inflammatory mediators
00:25:28.160 --> 00:25:36.440
and the niacinamide is safe up to at least a couple hundred milligrams but I think I've
00:25:36.440 --> 00:25:43.840
seen people with brain, terminal brain diseases cure themselves taking just 150 or 200 of
00:25:43.840 --> 00:25:45.920
niacinamide per day.
00:25:45.920 --> 00:25:56.640
Okay, so and B7 is biotin. I hear people say that that will reduce your blood, your glucose
00:25:56.640 --> 00:26:01.120
levels but then I read and I say, "Well gee, maybe that's not true. Maybe it actually regulates
00:26:01.120 --> 00:26:12.760
them dynamically." So what about biotin? Is there any negatives to taking biotin in
00:26:12.760 --> 00:26:16.760
like 5 to 10,000? I think it's micrograms, not milligrams.
00:26:16.760 --> 00:26:23.760
I've seen the good results from very, very big doses of biotin but 50 years ago, some
00:26:23.760 --> 00:26:31.320
animal studies showed that a moderate overdose could cause liver cancer. So I've always been
00:26:31.320 --> 00:26:36.320
leery about it but I've never seen people repeating those experiments.
00:26:36.320 --> 00:26:42.480
What's a dose? I mean what, so is 5,000 an excessive dose, micrograms or are you talking
00:26:42.480 --> 00:26:43.480
about something like...
00:26:43.480 --> 00:26:47.240
I would stick to around one milligram of biotin.
00:26:47.240 --> 00:26:54.240
Okay, one milligram. Okay, gotcha. Okay, and then folic acid, you're kind of, I mean I've
00:26:54.240 --> 00:27:00.600
read that you somehow think that's like somehow dangerous to take at all. I could be wrong
00:27:00.600 --> 00:27:02.000
too but that's what I've read.
00:27:02.000 --> 00:27:09.200
I think it's safe for the dose of around one milligram, maybe as high as five milligrams
00:27:09.200 --> 00:27:18.040
per day but you have to be cautious with especially vitamin B2 and folic acid because something
00:27:18.040 --> 00:27:25.480
in the synthetic process makes a lot of people get migraine headaches and hemorrhoids and
00:27:25.480 --> 00:27:33.720
other very intense symptoms from those which happen to be yellow molecules and I think
00:27:33.720 --> 00:27:42.440
it's something about their sensitivity to light and oxidation that makes the pure chemical
00:27:42.440 --> 00:27:44.600
pretty allergenic for a lot of people.
00:27:44.600 --> 00:27:48.720
So could it give you a rash too or something like that or just a headache?
00:27:48.720 --> 00:27:52.440
I didn't hear that.
00:27:52.440 --> 00:27:55.800
Could it give you a rash or just a headache?
00:27:55.800 --> 00:28:03.600
The worst symptoms I've heard about are migraine-like headaches and bowel problems but that could
00:28:03.600 --> 00:28:08.120
be the bowel inflammation can lead to rashes.
00:28:08.120 --> 00:28:14.560
Okay that makes sense and then B12, I really almost see almost no writing on that or just
00:28:14.560 --> 00:28:18.480
curious because a lot of people say you've got to have your B12 up and I know that gets
00:28:18.480 --> 00:28:25.200
to methylation but is there an amount or is it the amount that you consume in your basic
00:28:25.200 --> 00:28:26.800
diet should be more than enough?
00:28:26.800 --> 00:28:34.520
Yeah, if you eat animal products in particular and the intestine bacteria can make a lot
00:28:34.520 --> 00:28:35.520
of it.
00:28:35.520 --> 00:28:44.120
I hear from a lot of people with small intestine inflammation who have about 50% higher than
00:28:44.120 --> 00:28:50.760
the upper normal range for B12 apparently because their bacteria are thriving where
00:28:50.760 --> 00:28:52.160
they shouldn't be.
00:28:52.160 --> 00:28:57.920
Alright, I appreciate your questions, Cora and I've got to get on with the questions
00:28:57.920 --> 00:29:03.040
that I've got for Dr. Peat surrounding last month's March's radio show so we can get into
00:29:03.040 --> 00:29:04.280
some fresh topic.
00:29:04.280 --> 00:29:11.920
Dr. Peat, I wanted to go over the article just briefly that was written by this professor
00:29:11.920 --> 00:29:16.000
at the University of Uppsala in Sweden who is an expert on brain metabolism and sex hormones
00:29:16.000 --> 00:29:22.280
just to illustrate to people how wrong things can get from the quote unquote academic professionals
00:29:22.280 --> 00:29:29.760
and just to see how this was twisted in terms of what I'm about to speak verbatim from the
00:29:29.760 --> 00:29:35.720
article and I just want to stop you at different points during this just to hear your side
00:29:35.720 --> 00:29:39.560
of it so that you can point people in the right direction because people are going to
00:29:39.560 --> 00:29:44.520
read these things on ResearchGate or PubMed or other places and just take it as the truth
00:29:44.520 --> 00:29:49.840
because it's written by a university professor who specializes in this kind of thing but
00:29:49.840 --> 00:29:54.200
just want to bring the truth home again wherever possible.
00:29:54.200 --> 00:30:02.160
So an article was written about pregnenolone and progesterone and saying that basically
00:30:02.160 --> 00:30:08.920
the negative associations with it were fairly rife and so just going through what she had
00:30:08.920 --> 00:30:15.160
written, she talked about PMS and saying that for some people it was unpredictable and for
00:30:15.160 --> 00:30:19.760
many it was hard to explain but feelings of worry associated with the menstrual cycle
00:30:19.760 --> 00:30:25.200
had very specific cause and that this was the same hormone used in much birth control
00:30:25.200 --> 00:30:30.360
and that 85% of women experience premenstrual stress or PMS in the days leading up to the
00:30:30.360 --> 00:30:36.600
period and according to the American Congress of Obstetricians and Gynecologists as well
00:30:36.600 --> 00:30:41.520
this condition comes with physical symptoms like painful joints or breasts, headaches,
00:30:41.520 --> 00:30:46.800
sleeplessness etc and I'm sure most women can identify with these symptoms and she says
00:30:46.800 --> 00:30:52.080
it's pretty much down to one hormone progesterone and she's the leading expert on brain metabolism
00:30:52.080 --> 00:30:57.000
and sex hormone so she goes on to mention that progesterone appears after ovulation
00:30:57.000 --> 00:31:01.400
one of the two main female hormones the other being estrogen and it's present in the first
00:31:01.400 --> 00:31:07.600
two weeks of the cycle and has a broadly positive effect on news so this is estrogen. Estrogen
00:31:07.600 --> 00:31:12.520
increases the brain's serotonin the hormone most associated with happiness progesterone
00:31:12.520 --> 00:31:17.040
on the other hand can have a depressing effect so Dr. Peat what do you think about maintaining
00:31:17.040 --> 00:31:26.520
this sentence even just regarding serotonin's positive effects? To be polite I think it's
00:31:26.520 --> 00:31:42.680
very very silly everything there is confused and backwards for example the serotonin thing
00:31:42.680 --> 00:31:57.640
is a happiness signal serotonin is very essential for the inflammation, osteoporosis, cancer,
00:31:57.640 --> 00:32:06.720
blood clotting, spasms all sorts of bad effects inflammatory processes right from an excess
00:32:06.720 --> 00:32:16.360
inflammatory processes dictated by serotonin. Yeah it's right there with histamine as the
00:32:16.360 --> 00:32:23.480
most intense acute local inflammatory signal and in the brain that inflammatory process
00:32:23.480 --> 00:32:34.960
of serotonin turns on the whole stress system that activates ACTH and cortisol. Estrogen
00:32:34.960 --> 00:32:42.480
not only activates that serotonin dependent pathway but it directly activates the adrenal
00:32:42.480 --> 00:32:52.280
glands to produce cortisol so estrogen is a basic stress hormone serotonin is kind of
00:32:52.280 --> 00:33:02.320
a terminal mediator of that stress process turning on the defensive anti-stress cortisol
00:33:02.320 --> 00:33:10.640
production but in itself serotonin is a very powerful bone destroyer by its inflammatory
00:33:10.640 --> 00:33:17.040
process. It's basically an alarm signal no? Yeah. Okay well she without I guess laboring
00:33:17.040 --> 00:33:23.160
that point she mentions as well as creating anxiety another side effect of progesterone
00:33:23.160 --> 00:33:28.840
could be to cause a blues according to research by Torbjorn Backstrom from the University
00:33:28.840 --> 00:33:33.560
of Umeå in Sweden it seems to have the same effect on the brain as depressive drugs like
00:33:33.560 --> 00:33:39.080
alcohol and sleeping pills so where does she get that from that progesterone has this depressant
00:33:39.080 --> 00:33:48.960
effect? That's a very interesting confusion of the meaning of depression in the heart
00:33:48.960 --> 00:34:01.600
for example progesterone depresses the spastic activity that leads to cardiac arrest and
00:34:01.600 --> 00:34:10.560
it depresses the premature contractions and facilitates a good rhythm. Estrogen has the
00:34:10.560 --> 00:34:18.080
opposite effect tends to produce arrhythmia by delaying the ability to regain its energy
00:34:18.080 --> 00:34:26.640
charge and get ready for the next beat. Okay alright so she also goes on to say most substances
00:34:26.640 --> 00:34:31.240
in the body including hormones get broken down into other substances known as metabolites
00:34:31.240 --> 00:34:35.420
before eventually being removed by the kidney or the liver when progesterone is broken down
00:34:35.420 --> 00:34:39.880
its metabolites become active in the brain and it appears they and one in particular
00:34:39.880 --> 00:34:45.960
allopregnanolone that we mentioned last month sorry in March allopregnanolone and pregnanolone
00:34:45.960 --> 00:34:55.120
which both incidentally can be produced in the CNS both in the oligodendrocytes and astrocytes
00:34:55.120 --> 00:35:00.160
so it's not you know you don't have to consume this product it's actually de novo synthesis
00:35:00.160 --> 00:35:05.520
from cholesterol and she says these in particular allopregnanolone binds to a system called
00:35:05.520 --> 00:35:11.640
the GABA-A receptor now we've mentioned and I've talked about the GABA-A receptor in relation
00:35:11.640 --> 00:35:18.040
to things that bind to the GABA-A receptor to produce relaxation like valerian because
00:35:18.040 --> 00:35:26.840
it is the opposite to the excitotoxic system but she says that the GABA-A receptor is a
00:35:26.840 --> 00:35:30.920
little like the brain's police force it regulates making sure there isn't too much excitement
00:35:30.920 --> 00:35:36.400
going on which seems seems okay on the face of it and drugs that bind to it may cause
00:35:36.400 --> 00:35:41.040
it to step up policing and Backstrom's research suggests that metabolites of progesterone
00:35:41.040 --> 00:35:48.080
may be doing the same thing so if female hormones have such distinct effects the next step is
00:35:48.080 --> 00:35:52.560
to wonder why the female body is designed in this way and she suggests that it's more
00:35:52.560 --> 00:35:58.000
a result of evolutionary design meeting modern living progesterone's effects she goes on
00:35:58.000 --> 00:36:02.000
to say may be particularly pronounced now because women are having far more periods
00:36:02.000 --> 00:36:06.600
and far fewer children than in the thousands of malnourished years before birth control
00:36:06.600 --> 00:36:12.920
like birth control as a popular popularly appreciated product anyway 300 years ago women
00:36:12.920 --> 00:36:17.840
started menstruating around 17 or 18 because they were less healthy than today so I'm not
00:36:17.840 --> 00:36:22.000
too sure what you got to say about being less healthy and having a later menarche which
00:36:22.000 --> 00:36:27.320
you've actually said and is well and shown that it's actually a positive thing to actually
00:36:27.320 --> 00:36:32.920
have your period start early is actually related to high estrogen it's actually a very detrimental
00:36:32.920 --> 00:36:40.600
to your long-term health isn't it yeah the age at menarche is getting lower and lower
00:36:40.600 --> 00:36:50.120
all the time over the last several decades and that is now known to correspond to all
00:36:50.120 --> 00:36:58.440
of the the estrogen problems later in life one of the recent groups of studies related
00:36:58.440 --> 00:37:10.280
to the early puberty and the tendency to have autistic babies the uterus during gestation
00:37:10.280 --> 00:37:18.680
it has a higher estrogen level in the women who started at a very young age okay she goes
00:37:18.680 --> 00:37:22.600
on to say that most women got pregnant almost immediately you know several hundred years
00:37:22.600 --> 00:37:28.520
ago without birth control and remain pregnant or breastfeeding for most of their reproductive
00:37:28.520 --> 00:37:36.840
lives which ended around 40 now this this would have subjected them to a fairly sustained
00:37:36.840 --> 00:37:47.520
level of progesterone correct through being pregnant yeah she seems to get it just exactly
00:37:47.520 --> 00:37:57.160
wrong with pregnancy as a time of the low progesterone but the normal cycling woman
00:37:57.160 --> 00:38:05.640
produces maybe 30 milligrams a day during the luteal phase before menstruation and the
00:38:05.640 --> 00:38:15.880
ovaries weighing six or seven grams maybe are working pretty efficiently when they can
00:38:15.880 --> 00:38:24.640
produce 30 milligrams a day but the placenta in the term pregnancy weighs about a pound
00:38:24.640 --> 00:38:35.240
and a half roughly a hundred times bigger than the ovaries and it can produce at least
00:38:35.240 --> 00:38:43.000
30 times as much progesterone per day and there's a an interesting discussion of the
00:38:43.000 --> 00:38:54.120
effect of pregnancy on aging and general health in the book by a a a v everett and others
00:38:54.120 --> 00:39:05.000
called hypothalamus pituitary and aging in which he describes experiments mating rabbits
00:39:05.000 --> 00:39:10.400
constantly as soon as they have a live litter mate them again so that they live their whole
00:39:10.400 --> 00:39:22.800
lives producing a maximum number of litters and others that were not mated the the multi
00:39:22.800 --> 00:39:31.000
litter rabbits were had much more flexible young connective tissue their tissues were
00:39:31.000 --> 00:39:38.000
less aged at the end of their lives than the non-mated and they mentioned studies done
