WEBVTT
00:00:00.000 --> 00:00:02.320
Okay, here we go, hour two of our little show.
00:00:02.320 --> 00:00:04.960
As I mentioned to Mr. Peat in an email,
00:00:04.960 --> 00:00:06.320
and also to you, Adam Bergstrom,
00:00:06.320 --> 00:00:08.560
who's a good friend and great researcher,
00:00:08.560 --> 00:00:12.160
and he's on our show, oh, several times a month,
00:00:12.160 --> 00:00:14.460
even more sometimes, and he's a fan
00:00:14.460 --> 00:00:17.080
and knows a lot about the work of Mr. Ray Peat.
00:00:17.080 --> 00:00:17.920
He's on the line.
00:00:17.920 --> 00:00:19.160
Adam, are you there?
00:00:19.160 --> 00:00:20.000
- I am here.
00:00:20.000 --> 00:00:20.960
- There you are.
00:00:20.960 --> 00:00:25.280
Ray Peat is a PhD in biology from University of Oregon.
00:00:25.280 --> 00:00:28.320
His specialization in physiology,
00:00:28.320 --> 00:00:30.920
the schools he's taught in include University of Oregon,
00:00:30.920 --> 00:00:33.320
Urbana College, Montana State University,
00:00:33.320 --> 00:00:35.620
National College of Naturopathic Medicine.
00:00:35.620 --> 00:00:39.680
He started his work with progesterone
00:00:39.680 --> 00:00:42.920
and related hormones in 1968,
00:00:42.920 --> 00:00:46.320
and in papers in physiological chemistry and physics.
00:00:46.320 --> 00:00:48.660
I mean, he's got such an incredible background
00:00:48.660 --> 00:00:51.180
and very well respected around the world,
00:00:51.180 --> 00:00:52.440
Ray Peat, and he's on the line.
00:00:52.440 --> 00:00:54.040
Mr. Peat, good morning.
00:00:54.040 --> 00:00:54.880
- Good morning.
00:00:54.880 --> 00:00:55.720
- How you doing?
00:00:55.720 --> 00:00:57.320
It's been a while.
00:00:57.320 --> 00:00:59.120
- Yeah, I guess five years.
00:00:59.120 --> 00:01:00.680
- Has it been five years?
00:01:00.680 --> 00:01:01.520
(Ray laughs)
00:01:01.520 --> 00:01:02.480
Yeah, yeah.
00:01:02.480 --> 00:01:04.320
What are you most passionate about these days,
00:01:04.320 --> 00:01:05.800
Mr. Ray Peat, and your work?
00:01:05.800 --> 00:01:08.840
And by the way, Ray, say hi to Adam Bergstrom.
00:01:08.840 --> 00:01:10.040
- Oh, yeah, hi.
00:01:10.040 --> 00:01:13.240
I've read his stuff on the yellow fat disease.
00:01:13.240 --> 00:01:15.420
Very, very great work.
00:01:15.420 --> 00:01:17.640
- Thank you, Ray.
00:01:17.640 --> 00:01:18.640
Thank you very much.
00:01:18.640 --> 00:01:20.880
Thank you for turning me on to the concept
00:01:20.880 --> 00:01:23.040
because the first time I ever heard the words
00:01:23.040 --> 00:01:24.080
was out of your mouth.
00:01:24.080 --> 00:01:24.920
- Oh.
00:01:24.920 --> 00:01:27.760
- And you mentioned it on Patrick's show, too.
00:01:27.760 --> 00:01:28.600
- Oh, really?
00:01:28.600 --> 00:01:30.320
- The last time, yes, you did.
00:01:30.320 --> 00:01:34.040
- When did you first get turned on
00:01:34.040 --> 00:01:35.720
to the yellow fat thing, Ray?
00:01:35.720 --> 00:01:39.920
- Oh, in the 1940s.
00:01:39.920 --> 00:01:45.800
A family friend of ours was a chinchilla farmer,
00:01:45.800 --> 00:01:50.800
and he found that fish were poisoning his chinchillas.
00:01:51.200 --> 00:01:56.200
But that made me check the idea of essential fatty acids.
00:01:56.200 --> 00:02:00.400
And at that time, in the late '40s and early '50s,
00:02:00.400 --> 00:02:05.400
anytime someone mentioned the idea of essential fatty acids,
00:02:05.400 --> 00:02:10.520
it was very tentative because in Texas,
00:02:10.520 --> 00:02:18.440
one of the research institutes,
00:02:18.440 --> 00:02:20.960
I don't remember the exact name of it,
00:02:20.960 --> 00:02:25.240
1946 demonstrated that the so-called
00:02:25.240 --> 00:02:27.920
fatty acid deficiency disease
00:02:27.920 --> 00:02:30.560
was really a vitamin B6 deficiency
00:02:30.560 --> 00:02:33.680
because they could feed them a fat-free diet,
00:02:33.680 --> 00:02:37.440
cause the scaly skin symptoms and so on,
00:02:37.440 --> 00:02:41.520
and cure the disease with a supplement of vitamin B6
00:02:41.520 --> 00:02:43.280
without any fat added.
00:02:43.280 --> 00:02:46.440
So I sort of grew up with the concept
00:02:46.440 --> 00:02:51.440
that the fatty acid essentiality is,
00:02:51.440 --> 00:02:55.960
first it was a mistake and then it turned into a fraud.
00:02:55.960 --> 00:03:02.440
And then in the 1970s, I saw research
00:03:02.440 --> 00:03:07.240
in which they fed saturated fat
00:03:07.240 --> 00:03:10.960
or highly polyunsaturated fats,
00:03:10.960 --> 00:03:15.400
or a mixture to rats through their whole lifetime.
00:03:15.400 --> 00:03:18.440
And they found that it wasn't the quantity of fat
00:03:18.440 --> 00:03:23.440
that made them obese, it was the degree of unsaturation,
00:03:23.440 --> 00:03:26.880
so that the ones that ate saturated fats,
00:03:26.880 --> 00:03:30.400
such as coconut oil, were lean at the end of their lives,
00:03:30.400 --> 00:03:32.440
no matter how much they ate.
00:03:32.440 --> 00:03:37.240
And the ones that ate only polyunsaturated fat
00:03:37.240 --> 00:03:39.320
were fat at the end of their lives,
00:03:39.320 --> 00:03:42.200
even if they had a low-fat diet.
00:03:42.200 --> 00:03:44.120
- Now Adam, you jump in anytime, you don't need me.
00:03:44.120 --> 00:03:46.760
You can just jump in, we're just having a combo here.
00:03:46.760 --> 00:03:50.160
So these are the classic things Ray P. called PUFAs,
00:03:50.160 --> 00:03:52.560
polyunsaturated fatty acids.
00:03:52.560 --> 00:03:55.800
- Highly unsaturated fatty acids,
00:03:55.800 --> 00:03:59.280
omega-3s mainly, DHA, EPA, ALA.
00:03:59.280 --> 00:04:06.400
- Yeah, those are so sensitive to oxygen degradation
00:04:06.400 --> 00:04:13.000
that people have checked the blood content
00:04:13.000 --> 00:04:16.280
after someone eats a fatty fish
00:04:16.280 --> 00:04:18.880
and finds that very little of them
00:04:18.880 --> 00:04:20.920
even reach the bloodstream.
00:04:20.920 --> 00:04:25.280
And when they do, they're an oxidized breakdown product.
00:04:25.280 --> 00:04:29.840
The great majority of the fat is degraded
00:04:29.840 --> 00:04:32.040
by the time it gets into your bloodstream.
00:04:32.040 --> 00:04:33.440
- Really?
00:04:33.440 --> 00:04:37.560
So overall, then, we humans, you don't think,
00:04:37.560 --> 00:04:41.440
Ray P., we need to be eating any fish at all?
00:04:42.880 --> 00:04:45.720
- Only because of the trace minerals
00:04:45.720 --> 00:04:49.200
that are reliably in seafood.
00:04:49.200 --> 00:04:54.960
Selenium and iodine, for example, aren't reliable.
00:04:54.960 --> 00:04:59.040
If you eat foods grown only in one locality,
00:04:59.040 --> 00:05:02.440
you can become deficient in a particular trace mineral.
00:05:02.440 --> 00:05:05.840
- In your opinion, any fish better than others to eat,
00:05:05.840 --> 00:05:07.600
if you're gonna have a little fish?
00:05:07.600 --> 00:05:11.440
- Oh, yeah, the low-fat fish and the shellfish.
00:05:11.440 --> 00:05:14.280
Shellfish are great sources of copper
00:05:14.280 --> 00:05:18.240
because they generally don't use iron.
00:05:18.240 --> 00:05:24.280
Oysters are high in iron, but squid is very good.
00:05:24.280 --> 00:05:28.320
It's low in iron and high in copper
00:05:28.320 --> 00:05:33.320
and has selenium and iodine and other trace minerals.
00:05:33.320 --> 00:05:38.720
Cod and sole are low-fat fish that are safe.
00:05:38.720 --> 00:05:40.440
- Cod and sole, huh?
00:05:40.440 --> 00:05:42.120
- Mm-hmm. - Oh, oh.
00:05:42.120 --> 00:05:46.000
So, but these fatty fish, you eat 'em
00:05:46.000 --> 00:05:48.400
before they even get to where they're going,
00:05:48.400 --> 00:05:50.360
they start causing the body a problem?
00:05:50.360 --> 00:05:54.680
- Yeah, if you take, say, a fish oil supplement
00:05:54.680 --> 00:05:57.580
and then look in your bloodstream,
00:05:57.580 --> 00:06:02.600
there's enough of the oxidized fat already
00:06:02.600 --> 00:06:05.080
to suppress the immune system.
00:06:05.080 --> 00:06:08.720
That's why they use them as anti-inflammatories,
00:06:08.720 --> 00:06:11.520
but the trouble is that they accumulate
00:06:11.520 --> 00:06:16.520
and create progressive suppression of your immune system.
00:06:16.520 --> 00:06:20.600
And people talk about them being required
00:06:20.600 --> 00:06:23.160
for the brain structure because if you look
00:06:23.160 --> 00:06:28.160
at an adult's brain, it's full of fish oil equivalent.
00:06:28.160 --> 00:06:33.480
But a newborn, there have been many publications
00:06:34.360 --> 00:06:37.800
saying that when they check the brain
00:06:37.800 --> 00:06:42.800
of a newly born, say, miscarriage,
00:06:42.800 --> 00:06:48.580
they find that the brain is very low
00:06:48.580 --> 00:06:51.320
in polyunsaturated fatty acids.
00:06:51.320 --> 00:06:56.320
And so they say you must supplement pregnant women
00:06:56.320 --> 00:06:59.160
with fish oil or the equivalent
00:06:59.160 --> 00:07:03.480
because babies are being born with a brain deficiency
00:07:03.480 --> 00:07:08.480
of PUFA, but in France, there was a study
00:07:08.480 --> 00:07:12.560
in which they did give a PUFA supplement
00:07:12.560 --> 00:07:16.080
to pregnant women, figuring that they would advance
00:07:16.080 --> 00:07:21.080
brain development, and so they gave a sound test
00:07:21.080 --> 00:07:26.360
to the woman's abdomen to measure the baby's response.
00:07:26.360 --> 00:07:31.360
They found that the babies learned more slowly
00:07:32.240 --> 00:07:37.240
in utero if they had extra PUFA added to the diet,
00:07:37.240 --> 00:07:41.120
and they were born with smaller brains.
00:07:41.120 --> 00:07:43.820
And that shouldn't have been done in humans
00:07:43.820 --> 00:07:48.240
because already in the 1960s and '70s,
00:07:48.240 --> 00:07:50.560
experiments were showing that animals,
00:07:50.560 --> 00:07:56.200
if the mother was fed a diet high in unsaturated fat,
00:07:56.200 --> 00:08:01.200
the babies were born small-brained and slow learners.
00:08:01.340 --> 00:08:05.940
If they were low in PUFA but fed, for example,
00:08:05.940 --> 00:08:09.100
saturated fat, the babies had bigger brains
00:08:09.100 --> 00:08:10.640
and learned faster.
00:08:10.640 --> 00:08:17.020
- Are any of these unsaturated fats, like olive oil,
00:08:17.020 --> 00:08:19.940
in your opinion, are good food?
00:08:19.940 --> 00:08:24.080
- It's about 8% or 10% or 11% PUFA.
00:08:24.080 --> 00:08:25.820
The rest of it is very good fat.
00:08:25.820 --> 00:08:30.500
So if you hold it down to one or two teaspoons per day,
00:08:30.500 --> 00:08:31.340
you're safe.
00:08:31.340 --> 00:08:37.700
All during the growth time up to the age of 20,
00:08:37.700 --> 00:08:43.140
the body is diluting the PUFA in the diet.
00:08:43.140 --> 00:08:46.780
So the brain isn't seriously impaired
00:08:46.780 --> 00:08:48.700
until about the age of 20.
00:08:48.700 --> 00:08:52.700
When you stop growing in size and volume,
00:08:52.700 --> 00:08:56.940
the brain and other tissues begin increasing
00:08:56.940 --> 00:08:58.740
their concentration of PUFA.
00:08:59.620 --> 00:09:02.820
So from 20 to the mid-40s,
00:09:02.820 --> 00:09:06.660
the brain is becoming more and more polyunsaturated
00:09:06.660 --> 00:09:11.140
and so more at risk of stress.
00:09:11.140 --> 00:09:14.740
When you're under stress, you release these,
00:09:14.740 --> 00:09:18.380
any of the stored PUFA into the bloodstream
00:09:18.380 --> 00:09:21.820
where they can become oxidized and toxic.
00:09:21.820 --> 00:09:25.700
- So in the fish oil and the APA/DHA arena,
00:09:25.700 --> 00:09:28.060
not only what you're talking about,
00:09:28.060 --> 00:09:31.460
isn't there also the issues of these things being rancid,
00:09:31.460 --> 00:09:34.020
the way they're produced and stored and such?
00:09:34.020 --> 00:09:37.700
- Oh yeah, that gives a head start on the problem.
00:09:37.700 --> 00:09:38.540
- Yeah, wow.
00:09:38.540 --> 00:09:43.260
- But even if you eat the most perfectly fresh PUFA,
00:09:43.260 --> 00:09:46.140
by the time it reaches your stomach, it's deteriorating.
00:09:46.140 --> 00:09:49.540
And then when it gets into the tissue, it's farther along.
00:09:49.540 --> 00:09:54.180
And some of it reaches your brain and is stored for years.
00:09:54.180 --> 00:09:57.260
But then every night,
00:09:57.260 --> 00:10:00.580
your brain is renewing itself considerably.
00:10:00.580 --> 00:10:03.140
But unfortunately, during the night,
00:10:03.140 --> 00:10:05.420
your free fatty acids in the blood
00:10:05.420 --> 00:10:09.740
coming out of your fat tissues rise.
00:10:09.740 --> 00:10:12.820
And so the brain is trying to renew itself.
00:10:12.820 --> 00:10:15.380
But what it finds in your bloodstream
00:10:15.380 --> 00:10:20.380
by the time you're 40 is polyunsaturated fatty acids
00:10:21.140 --> 00:10:23.920
that add to the damage of the brain.
00:10:23.920 --> 00:10:28.740
So that every night, when you're over the age of 40,
00:10:28.740 --> 00:10:34.020
your brain is at risk of deteriorating faster.
00:10:34.020 --> 00:10:35.780
- Oh great, that's all we need, right?
00:10:35.780 --> 00:10:36.980
(laughing)
00:10:36.980 --> 00:10:37.940
Ray Peat is with us,
00:10:37.940 --> 00:10:39.860
and Adam Berkstrom's co-hosting the show today
00:10:39.860 --> 00:10:42.940
'cause he's done a lot of research with Mr. Peat,
00:10:42.940 --> 00:10:47.380
Patrick Tempone, patricktempone1radionetwork.com.
00:10:47.380 --> 00:10:48.580
If you'd like to join the show,
00:10:48.580 --> 00:10:53.580
patricktempone1radionetwork.com.
00:10:53.580 --> 00:10:55.740
Adam, what's the most fascinating thing
00:10:55.740 --> 00:10:59.260
you've kind of picked up on the whole yellow fat thing
00:10:59.260 --> 00:11:03.060
that you were first alerted to with Ray Peat?
00:11:03.060 --> 00:11:07.300
- I found references of it also causing brown heart disease,
00:11:07.300 --> 00:11:11.720
and it was known that cod liver oil was a cause of it
00:11:11.720 --> 00:11:14.340
at about the time of the Civil War.
00:11:14.340 --> 00:11:16.460
And there's several references,
00:11:16.460 --> 00:11:19.980
maybe about a half a dozen or close to a dozen
00:11:19.980 --> 00:11:22.420
that I've found from that time.
00:11:22.420 --> 00:11:25.780
So this has been known for a long time.
00:11:25.780 --> 00:11:28.620
And also, people forget that in 1982,
00:11:28.620 --> 00:11:32.800
in the book "Life Extension" by Dirk Pearson and Sandy Shaw,
00:11:32.800 --> 00:11:36.420
they basically told you to walk big circles
00:11:36.420 --> 00:11:41.420
around omega-3s, and mentioned specifically DHA and EPA.
00:11:43.380 --> 00:11:48.380
And the author of "Never Cry Wolf", I believe,
00:11:48.380 --> 00:11:53.420
Farley Mowat, he also recommended avoiding fish,
00:11:53.420 --> 00:11:57.340
and that the Inuit avoided fish,
00:11:57.340 --> 00:12:00.100
and it was the government that gave them nets.
00:12:00.100 --> 00:12:01.700
The Canadian government gave them nets,
00:12:01.700 --> 00:12:03.880
and they wouldn't use it because they knew
00:12:03.880 --> 00:12:06.940
if they ate just those fish, those cold water fish,
00:12:06.940 --> 00:12:07.900
they would die.
00:12:07.900 --> 00:12:11.600
And that is in his book about the Inuit,
00:12:12.600 --> 00:12:15.420
the people of the deer, I believe it's called.
00:12:15.420 --> 00:12:16.260
- Fascinating.
00:12:16.260 --> 00:12:22.180
Ray Pede, so the DHA, EPA molecule, or whatever it is,
00:12:22.180 --> 00:12:23.180
do we need any of this?
00:12:23.180 --> 00:12:26.120
Like, just go right straight to some seaweeds,
00:12:26.120 --> 00:12:28.540
or I don't know, something, do we need it?
00:12:28.540 --> 00:12:29.980
And do we get it in other places
00:12:29.980 --> 00:12:34.180
other than fish oils and stuff?
00:12:34.180 --> 00:12:38.960
- No, if we eat only sugar, for example, for calories,
00:12:39.920 --> 00:12:44.920
we synthesize the monounsaturated fat,
00:12:44.920 --> 00:12:50.420
such as is the main fat of olive oil, oleic acid.
00:12:50.420 --> 00:12:55.420
And from oleic acid, whether we get it from a good food,
00:12:55.420 --> 00:12:58.980
like olive oil, or make it from our own sugar
00:12:58.980 --> 00:13:03.700
or starch in our diet, that can be unsaturated.
00:13:03.700 --> 00:13:08.700
And the normal polyunsaturated fat in our brain at birth,
00:13:09.680 --> 00:13:14.680
is made from glucose by first making oleic acid
00:13:14.680 --> 00:13:19.720
and then unsaturating that.
00:13:19.720 --> 00:13:24.720
And these are omega minus nine polyunsaturated fats.
00:13:24.720 --> 00:13:27.480
They are natural fat.
00:13:27.480 --> 00:13:30.340
An Australian researcher tested,
00:13:30.340 --> 00:13:35.340
he found an easy source of omega minus nine fatty acids,
00:13:36.600 --> 00:13:41.480
and found that they are very powerfully anti-inflammatory,
00:13:41.480 --> 00:13:44.620
and they don't break down and oxidize easily
00:13:44.620 --> 00:13:47.820
because they have nine carbons at the end
00:13:47.820 --> 00:13:51.700
that are saturated, which are very stable.
00:13:51.700 --> 00:13:56.700
And the acid at the other end is a stabilizing factor.
00:13:56.700 --> 00:14:03.800
So omega minus nine fats are natural
00:14:03.800 --> 00:14:05.620
and concentrate in the brain
00:14:05.620 --> 00:14:07.740
and give good brain function
00:14:07.740 --> 00:14:10.900
and good stability against oxidation.
00:14:10.900 --> 00:14:14.940
The whole concept of essential fatty acids,
00:14:14.940 --> 00:14:19.940
which was disproved in Texas in 1946,
00:14:19.940 --> 00:14:23.580
it was brought back in the 1950s,
00:14:23.580 --> 00:14:28.580
when the food oil industry found they had lots of,
00:14:28.580 --> 00:14:33.340
oh, cottonseed oil was the first.
00:14:33.340 --> 00:14:36.180
It was a byproduct of the cotton industry.
00:14:36.180 --> 00:14:40.580
And they were polluting the country
00:14:40.580 --> 00:14:42.860
with the waste cottonseed,
00:14:42.860 --> 00:14:45.580
and they found that they could extract the oil,
00:14:45.580 --> 00:14:50.580
make people eat it as a food lubricant, basically.
00:14:50.580 --> 00:14:56.340
There was a great campaign around 1950
00:14:56.340 --> 00:15:00.080
to sell Wesson oil, cottonseed oil.
00:15:01.020 --> 00:15:05.380
They gave recipes for making special pastries and cakes
00:15:05.380 --> 00:15:07.080
using that instead of butter.
00:15:07.080 --> 00:15:12.900
So it was all an advertising ploy, starting in the 1950s.
00:15:12.900 --> 00:15:13.740
- Yeah.
00:15:13.740 --> 00:15:18.640
- And people accepted the advertising,
00:15:18.640 --> 00:15:23.640
and people grew up believing in essential fatty acid concept.
00:15:23.640 --> 00:15:29.340
So when they went to medical school and did research,
00:15:29.340 --> 00:15:32.580
it became the official doctrine.
00:15:32.580 --> 00:15:37.580
And by the 1960s, people were already being poisoned
00:15:37.580 --> 00:15:43.880
by eating their cottonseed oil and soy oil and so on.
00:15:43.880 --> 00:15:48.820
The medical industry had convinced itself
00:15:48.820 --> 00:15:52.140
that there was such a thing as essential fatty acids,
00:15:52.140 --> 00:15:57.140
and that they were protecting, was the advertising line,
00:15:57.300 --> 00:16:00.460
they would protect you against cholesterol
00:16:00.460 --> 00:16:02.220
and saturated fats.
00:16:02.220 --> 00:16:06.340
And so they put several hundred veterans in Los Angeles
00:16:06.340 --> 00:16:11.340
on a diet with only the vegetable polyunsaturated fats,
00:16:11.340 --> 00:16:17.220
or a fairly normal diet containing some butter
00:16:17.220 --> 00:16:19.420
and cream and lard and so on.
00:16:19.420 --> 00:16:23.220
Not really a saturated fat, but just an average diet.
00:16:23.220 --> 00:16:25.060
At the end of eight years,
00:16:25.060 --> 00:16:28.500
there were three times as many cancer deaths
00:16:28.500 --> 00:16:33.220
in the group on vegetable oil as on the normal diet.
00:16:33.220 --> 00:16:35.340
And so they stopped the study and said,
00:16:35.340 --> 00:16:39.140
well, it doesn't protect against heart disease,
00:16:39.140 --> 00:16:39.980
so we'll stop.
00:16:39.980 --> 00:16:41.660
But they didn't advertise the fact
00:16:41.660 --> 00:16:45.340
that it greatly increased the cancer mortality,
00:16:45.340 --> 00:16:48.260
which had been known in animal studies already,
00:16:48.260 --> 00:16:50.560
but the medical industry fell
00:16:50.560 --> 00:16:53.820
for the food oil advertising line.
00:16:53.820 --> 00:16:55.420
- I grew up in the '50s, and I know,
00:16:55.420 --> 00:16:56.740
I had 'em probably did.
00:16:56.740 --> 00:16:57.980
I don't know how old you are, Ray,
00:16:57.980 --> 00:17:00.540
but I can remember the Western oil commercials.
00:17:00.540 --> 00:17:01.620
Boy, they were everywhere.
00:17:01.620 --> 00:17:02.660
Yeah. - Yeah.
00:17:02.660 --> 00:17:04.800
- Yeah, wow, everywhere.
00:17:04.800 --> 00:17:07.980
So in general, from good sources,
00:17:07.980 --> 00:17:12.580
most saturated fats are just fine to consume for us?
00:17:12.580 --> 00:17:18.500
- Yeah, and the trouble is that even the good fats,
00:17:20.300 --> 00:17:22.820
olive oil has eight or 10% PUFA,
00:17:22.820 --> 00:17:26.100
butter has two or 3%,
00:17:26.100 --> 00:17:29.140
even coconut oil has two or 3%.
00:17:29.140 --> 00:17:34.140
And these are, the cells don't prefer to oxidize those
00:17:34.140 --> 00:17:37.880
because they're dangerous and poison the mitochondria,
00:17:37.880 --> 00:17:40.820
so they're packed away in fat cells.
00:17:40.820 --> 00:17:45.820
And so even highly selected,
00:17:45.820 --> 00:17:48.300
so-called saturated fat diet,
00:17:48.300 --> 00:17:50.780
we're putting some of these in the storage
00:17:50.780 --> 00:17:54.100
and they're getting into the brain and fat tissues.
00:17:54.100 --> 00:17:57.740
And so by the time a person is 50,
00:17:57.740 --> 00:18:01.880
even if they've been reasonable in their diet choices,
00:18:01.880 --> 00:18:06.880
they're still gonna have too much of the PUFA in their body,
00:18:06.880 --> 00:18:10.620
and that makes you more susceptible to any stress
00:18:10.620 --> 00:18:13.760
when they come out and poison you more intensely.
00:18:13.760 --> 00:18:16.180
- Wow.
00:18:17.060 --> 00:18:18.580
- That's how you make--
00:18:18.580 --> 00:18:19.860
- Go ahead, Adam.
00:18:19.860 --> 00:18:22.660
- I was gonna say, it's how you make lipofuscin too.
00:18:22.660 --> 00:18:25.660
And lipofuscin now has been shown
00:18:25.660 --> 00:18:29.180
to be not just a passive waste product,
00:18:29.180 --> 00:18:34.180
but it groups into iron, zinc, and other toxic metals
00:18:34.180 --> 00:18:38.580
and uses them against the human body,
00:18:38.580 --> 00:18:41.420
and any body, except if you're a salmon
00:18:41.420 --> 00:18:44.760
listening to this show, then DHA is okay.
00:18:46.620 --> 00:18:50.380
In 1970, when I was working on my dissertation
00:18:50.380 --> 00:18:55.140
trying to understand why hamsters aged
00:18:55.140 --> 00:18:58.860
and became sterile halfway through their lifetime,
00:18:58.860 --> 00:19:03.860
I found that their uterus was accumulating lipofuscin,
00:19:03.860 --> 00:19:06.940
and so I studied it,
00:19:06.940 --> 00:19:11.940
and it becomes like a little oxygen-consuming,
