superfoods with a name like that they've
0:02
got to be super good for you and you
0:04
should definitely be eating more of them
0:06
let's talk about that
0:10
how's it going guys my name is richie
0:11
kirwan and today we're going to talk all
0:12
about one of my least favorite nutrition
0:17
what are they and do they actually live
0:19
up to the buzz as always i want to point
0:21
out that i'm not telling you what you
0:23
should or shouldn't eat that's entirely
0:25
your choice i do however want to help
0:27
you understand what the science behind
0:29
superfoods is to help you make more
0:31
informed choices let's get started okay
0:34
so the first thing to get really clear
0:35
about superfoods is that there is no set
0:38
definition for what a superfood actually
0:41
in a very general sense it's any food
0:44
that is either high in a particular
0:46
nutrient or nutrients or has some
0:48
apparent health benefit
0:50
that means that as long as you market it
0:52
from the right angle you can call almost
0:54
anything a superfood and nobody can
0:56
really say that you're wrong oh that
0:58
food has a load of fiber and helps you
1:00
poop better it's a superfood
1:02
oh that food has a load of plant-based
1:04
vitamin a and acts as an antioxidant
1:06
it's a superfood and it's also called a
1:08
carrot just remember that any time
1:10
someone refers to anything as a
1:11
superfood because the description is so
1:13
broad there isn't a set list of
1:15
superfoods and if you look up superfoods
1:17
online it all depends on what's trending
1:19
right now in the popularity charts which
1:21
is usually down to whatever people are
1:22
talking about on social media at the
1:24
moment so why i'm going to mention some
1:26
common superfoods here just to explain
1:28
why some people think they're super i'm
1:30
definitely not going to name all of them
1:31
so forgive me if i forget to include
1:34
the first group of superfoods i'll
1:36
mention are dark green leafy vegetables
1:39
these are vegetables like kale chard
1:42
spinach cabbage and add a stretch even
1:45
they're incredibly nutrient dense and
1:47
loaded with fiber folic acid calcium
1:49
magnesium iron although they're not as
1:51
bioavailable as the animal-based sources
1:53
meaning they're not absorbed as well on
1:55
top of that many of them have been shown
1:57
in some studies to have
1:59
anti-inflammatory and even anti-cancer
2:01
properties although the evidence for the
2:03
effect in humans still needs a lot more
2:07
that said they have been associated with
2:09
better cardiovascular health lower risk
2:11
of dementia and even type 2 diabetes the
2:14
next group of superfoods i'm going to be
2:16
doing this a lot by the way i think
2:18
worth mentioning are berries blueberries
2:20
raspberries blackberries strawberries
2:23
all have a few common traits they're
2:25
very low in calories compared to other
2:27
fruit and they're very rich in a group
2:29
of phytonutrients called polyphenols
2:32
these are pigments or the colors in
2:34
fruit and they have powerful
2:35
anti-inflammatory properties and
2:37
stimulate our bodies to increase the
2:39
level of our own antioxidant enzymes
2:42
this means they're very good for brain
2:44
and cardiovascular health and it's not
2:46
just plants that can be considered
2:49
salmon for example is often called a
2:50
superfood because of its high levels of
2:53
long-chain omega-3 fatty acids
2:54
especially epa and dha people who have a
2:58
higher intake of oily fish like salmon
2:59
are known to have a lower risk of heart
3:01
disease and better brain health as they
3:04
epa is especially important for heart
3:06
health due to its anti-inflammatory
3:07
properties and dha is really important
3:09
for brain health as it's found in large
3:11
quantities in brain tissue and just in
3:13
case you thought all superfoods were
3:15
completely unprocessed
3:17
dark chocolate also has a pretty good
3:18
health reputation in fact dark chocolate
3:21
the darker the better is loaded with
3:23
polyphenols too and other antioxidants
3:25
an irregular consumption of dark
3:26
chocolate is associated with better
3:28
heart health lower blood pressure and
3:30
even better memory and mood but then
3:32
again who's not going to be happy if
3:33
they're eating chocolate all the time
3:34
remember though dark chocolate is still
3:36
really high in calories so you don't
3:38
need to eat loads to get the benefits
3:40
now the next food which i personally
3:43
consider to be one of the most overrated
3:46
foods in both the nutrition and culinary
3:48
worlds and i'm probably going to get a
3:50
lot of hate for saying this
3:51
is the avocado yes it's loaded with
3:54
loads of heart-healthy monounsaturated
3:56
fat fiber and minerals like magnesium
3:59
but and maybe it's just me
4:01
i'm just not that into them
4:03
i have never once ordered avocado toast
4:05
and i don't think i ever will no
4:07
judgement if you like it though but yes
4:09
it is a good source of monounsaturated
4:11
fat next up chia seeds now while all
4:14
nuts and seeds have a lot of nutrients
4:16
in common like unsaturated fats that are
4:18
really good for heart health and fiber
4:19
which is good for gut health chia seeds
4:22
seem to be getting a lot of attention at
4:23
the moment that may be because they're
4:25
high in omega-3 fatty acids that aren't
4:28
that easy to find from other foods and
4:30
they have a lot of soluble fiber hence
4:32
why they're often used to make chia seed
4:35
the fiber in some nuts and seeds seems
4:36
to be really good at helping to control
4:39
appetite too in terms of super drinks
4:41
green tea seems to lead the pack
4:44
tea in general is actually the main
4:45
source of polyphenols in the uk diet
4:48
and these help to induce antioxidant
4:49
enzyme systems in the body and may help
4:51
to protect against some chronic diseases
4:53
like heart disease diabetes and even
4:55
cancer in particular green tea is high
4:57
in epigallocatechin gallate or egcg
5:00
which in experiments in cells in test
5:02
tubes seems to have a lot of beneficial
5:04
effects but we don't have enough
5:06
evidence from human trials to say that
5:10
that's one of the big issues with the
5:14
a lot of the buzz around them comes from
5:16
experiments in animals or in vitro
5:18
experiments where scientists test cells
5:20
growing in a petri dish
5:22
while that kind of research is really
5:23
important it can't tell us if something
5:25
actually has a beneficial effect in
5:27
humans that's why we need to be really
5:29
careful interpreting research not done
5:31
in humans the last of the apparent
5:33
superfoods i'll mention is turmeric it's
5:36
the spice that gives many curries their
5:37
distinctive yellow color it's been used
5:40
as a culinary and medicinal herb for
5:41
thousands of years and it's being seen
5:44
really really frequently in scientific
5:46
trials at the moment to test its
5:47
supposed benefits those benefits seem to
5:50
focus mostly around turmeric's
5:52
anti-inflammatory effects which seems to
5:54
have some particular benefits for pain
5:55
reduction like in joint pain again the
5:57
evidence isn't totally conclusive as to
5:59
how effective turmeric is but it's
6:02
definitely something worth keeping an
6:03
eye on now i know i may have come across
6:05
a little negative talking about all
6:06
these foods but i want to say here that
6:09
all of them can be amazing additions to
6:12
it's just not a problem if you don't eat
6:14
them the issue with the term superfoods
6:16
is that it almost gives the impression
6:18
that it's something that you have to eat
6:20
or you can just focus on that food
6:22
without really thinking about the
6:23
overall quality of your diet that helps
6:25
people market a product and jack up the
6:28
don't get me wrong i think promoting
6:30
fruit and vegetables and other nutrient
6:32
dense foods is amazing and actually it's
6:34
something that we definitely should be
6:37
just not if it excludes all the other
6:39
amazing fruit and veg that we're used to
6:42
in my opinion most whole foods can
6:44
probably be considered superfoods that's
6:46
because they all have something valuable
6:48
to contribute to the diet because most
6:50
fruits and vegetables and spices are
6:51
absolutely loaded with possibly
6:54
thousands of bioactive chemicals
6:56
these could have many different
6:58
potential benefits on our health and
6:59
that's why eating a varied diet of many
7:02
different plant foods is a good idea
7:04
even common foods have plenty of
7:05
potential benefits to offer like the
7:07
antioxidant lycopene in tomatoes or the
7:09
fiber beta glucan in oats or the protein
7:12
calcium and probiotic bacteria in greek
7:14
yogurt the greater variety of plant
7:17
foods in our diet the better
7:19
don't get hung up just on the ones with
7:22
a good marketing team
7:23
