you've heard a lot of people talking
0:01
about the carnivore diet but you don't
0:03
know why someone would want to eat just
0:05
meat let's talk about
0:08
[Music]
0:09
that how's it going guys my name is
0:12
Richie Kerwin and today we're going to
0:13
talk a little more about the carnivore
0:15
diet specifically we're going to talk
0:17
about why some people do it and whether
0:19
there's science behind any of those
0:21
reasons as always I want to point out
0:23
that I'm not telling you to follow or
0:25
not follow this diet in all my videos my
0:27
goal is to help explain some of the
0:29
science behind different aspects of diet
0:31
and nutrition my goal is to help you
0:33
understand how different diets foods and
0:35
nutrients affect our health so you can
0:38
use your own critical thinking to help
0:40
you make up your mind about what to do
0:42
with that information let's get started
0:45
just before we start it's worth
0:46
mentioning what the carnivore diet is
0:48
basically it's an all meat or
0:50
predominantly meat diet depending on the
0:52
person doing it they may include eggs
0:54
and some dairy products but the common
0:56
feature is a lot of meat and very little
0:58
are no plants at all not even spices
1:02
I've done another video on the health
1:04
effects of carnivore already which gives
1:06
a better explanation of what the diet is
1:08
so remember to check that out after this
1:10
video so why do people even do the
1:11
carnivore diet well one of the big
1:13
reasons that people speak about is
1:15
avoiding plant toxins you see some big
1:18
names in the carnivore Community like to
1:20
point out that while virtually all
1:21
animals are edible most plants aren't
1:24
now that's a perfectly valid fact that
1:26
unfortunately gets blown out of
1:28
proportion yes there are a lot of plants
1:31
that humans can't eat but there are also
1:33
over 7,000 plant species that we can a
1:36
common Trope in carnivore circles is
1:38
that plants produce toxins because they
1:40
don't want to be eaten so humans
1:43
shouldn't eat them because those toxins
1:45
will be bad for us it's a great story
1:48
but it doesn't really have a lot of
1:50
science to back it up plants do produce
1:52
a huge variety of phytochemicals and
1:55
they carry out a huge variety of
1:56
different roles in plants and some of
1:58
those are to help the plants defend
2:00
themselves there's a really important
2:01
saying that is very applicable in
2:03
nutrition and that's the dose makes the
2:06
poison what that means is that for a
2:08
substance to be toxic it needs to come
2:11
in a big enough dose the truth is if you
2:14
have too much of anything it can be bad
2:16
for you that's literally what too much
2:19
means in smaller doses many plant
2:22
chemicals actually have beneficial
2:24
effects on human health for example
2:25
there's a group of plant chemicals
2:26
called polyphenols and these are
2:28
believed to be responsible for the
2:30
health benefits of foods like
2:31
blueberries red wine tea coffee or even
2:34
broccoli some polyphenols work by a
2:36
process called heresis hormesis is where
2:38
our body receives a small dose of a
2:40
stressor like a plant chemical which
2:42
actually stimulates the body to activate
2:45
protective mechanisms which overall are
2:47
beneficial for health another good
2:49
example of hormesis is exercise exercise
2:52
is a stress that causes our body to
2:54
react and adapt and become healthier in
2:57
the long run and it's possible to have
2:59
too much exercise 2 which highlights the
3:01
fact that the dose does indeed make the
3:03
poison another reason some carnivores
3:05
follow the diet is because plants
3:07
contain antinutrients antinutrients are
3:10
substances in plants that can inhibit
3:12
the absorption of other nutrients or
3:14
have other negative health effects they
3:16
include substances like lectins oxalates
3:19
phytic acid and Tron Inhibitors and it's
3:21
true that antinutrients are part of the
3:23
reason that some nutrients are not as
3:25
well absorbed from plant foods does that
3:27
mean you need to avoid all antinutrients
3:30
not at all in fact we have a huge amount
3:32
of research that shows that higher plant
3:34
intakes leads to many beneficial Health
3:36
outcomes despite the fact that plants
3:39
contain antinutrients many foods that
3:41
have been researched again and again and
3:44
which continuously show benefits for
3:46
things like reducing risk of diabetes
3:48
reducing cholesterol levels improving
3:50
markers of inflammation helping with
3:52
weight loss all contain some
3:54
antinutrients and they're still
3:56
beneficial when it comes to nutrition we
3:58
have to remember to look at the big
3:59
bigger picture if a food contains many
4:02
Health promoting substances and a small
4:04
amount of not so beneficial substances
4:07
overall it will have a net positive
4:09
effect you see I don't have a major
4:11
issue with the carnivore diet per se but
4:14
I do have a major issue with the amount
4:15
of bad information that circulates in
4:18
many of the carnivore communities I hear
4:20
many of the same misconceptions again
4:22
and again and a lot of those
4:24
misconceptions stem from a focus on
4:26
mechanistic Research or research in
4:28
animal models
4:30
mechanistic research is done to help us
4:32
understand the biochemical mechanism of
4:34
how something works in the body it's
4:37
really Nitty Gritty science and it's an
4:39
important part of the scientific process
4:41
as is animal research the problem is
4:43
when someone takes a mechanistic study
4:45
and tries to use that to make dietary
4:48
recommendations you see our bodies are
4:50
really complex machines and don't always
4:53
do what we expect based on mechanistic
4:56
research for example omega-6
4:58
polyunsaturated fatty acids or pfas are
5:01
another substance that many people in
5:03
the carnivore Community seem to be
5:04
afraid of mechanistically omega-6 puas
5:06
are used to make two series of prag
5:09
glandon in our bodies and these are
5:11
involved in inflammation inflammation is
5:13
a perfectly natural process but an
5:15
excess of inflammation is associated
5:17
with a lot of chronic diseases like
5:18
diabetes and heart disease this has led
5:20
some people to believe that if you eat
5:21
Omega 6 proof of containing seed oils
5:23
you will increase your levels of
5:24
inflammation and be at a greater risk of
5:26
these diseases the thing is we have a
5:29
huge amount of research that shows that
5:30
Omega 6 don't lead to increases
5:32
inflammation in the body and higher
5:34
intakes of Omega 6 are often associated
5:36
with a lower risk of disease like
5:37
diabetes and heart disease the same goes
5:40
for animal studies because what happens
5:42
in animals with one food may not and
5:44
often doesn't happen the same way in
5:46
humans so you can't base your diet
5:48
choices on mechanistic data and animal
5:50
studies alone the good news is you don't
5:52
have to we have plenty of research from
5:54
rcts cohort studies and even
5:56
epidemiological data that helps us
5:58
better understand what's most likely to
6:00
be best for our health I say most likely
6:02
because science is never 100% but we can
6:05
use science to help us get closer to
6:07
certainty another benefit that is often
6:09
mentioned about the carnivore diet is
6:11
that animal products are nutrient-dense
6:13
and in general this is true animal foods
6:15
like meat fish eggs and dairy are
6:17
amazing sources of very bioavailable
6:20
nutrients like protein iron zinc B
6:22
vitamins iodine calcium choline and many
6:25
many more the problem is adding a lot of
6:27
fat to animal Foods reduces their
6:29
nutrient density you see nutrient
6:31
density is tough to quantify but in
6:32
general it's the amount of nutrients
6:35
provided divided by the amount of energy
6:38
or calories in the food 100 gr of lean
6:41
round steak provides about 2.3 milligram
6:43
of iron in only 15 calories so it's a
6:46
nutrient dense source of iron however if
6:49
you have 100 gr of a fatty cut of steak
6:51
like sirloin it has a little less iron
6:53
at about 1.5 mg and about 214 calories
6:56
because of less muscle and more fat
6:57
tissue so if you want the most nutrient
7:00
dense versions of certain animal Foods
7:02
in many cases lower fat or leaner
7:04
versions are better options not the
7:06
fatty options which are common on the
7:08
carnivore diet which brings me to butter
7:10
a common food for some on the carnivore
7:12
diet and a very nutrient poor food
7:15
because it's mostly just fat with very
7:18
few nutrients if any at all and finally
7:21
another major reason I hear from people
7:23
promoting carnivore diets is that there
7:25
are no essential substances that you can
7:27
get from plants that you can't get from
7:29
meat another way of saying this is that
7:31
certain substances in plants like
7:33
carbohydrates or fiber are not essential
7:36
to life so you don't need to eat them
7:39
this is a false dichotomy just because
7:42
something isn't essential to survival
7:44
doesn't mean you can't benefit from
7:46
having it in your diet you absolutely
7:48
can survive without eating carbs but
7:50
your diet might be a lot more fun and
7:52
your exercise performance might be a lot
7:54
better with them you can also absolutely
7:57
live life without eating fiber but
7:59
eating some may reduce your risk of
8:01
colon cancer you don't need a phone or a
8:03
tablet or shoes or a house to live but I
8:06
bet your life is a lot more comfortable
8:08
because you have them like I said at the
8:09
start I want people to understand the
8:11
real science behind how Nutrition Works
8:14
and that's hard for people to do when
8:15
they're bombarded with nutrition
8:17
misinformation and disinformation almost
8:20
every single day but I really hope it
8:22
has helped you to better understand and
8:24
think more critically about the
8:25
carnivore diet as always if you have any
