Importance of carbohydrates; fasts & proteins - Components of Food , Science, Class 6 Video Lecture

hello friends this video on components
of food part 7 is brought to you by
example comm no more your problems and
so we have been learning about so many
different types of nutrients how do we
test whether starch is present in a food
item or carbohydrate is present or
protein is present or fatty lesson the
question is why do we need all types of
nutrients ok so we say that
carbohydrates they provide this energy
missing fats they provide instant energy
we say proteins they also do something
good for each of these nutrients do some
good to us so why is it necessary that I
need to take all of them what if I take
only carbohydrates and by that so is
that going to affect me adversely yes so
here in this section we will look at the
importance of nutrients why are they so
important why are they so significant so
let us first talk about carbohydrates so
carbohydrate detriment provide energy to
the body and we saw that energy is
needed to perform any kind of activity
whether we want to perform a physical
work or the mental work everywhere we
need energy and this energy is provided
by the carbohydrates so some of the food
items which are rich in carbohydrates
are bread rice potato tortillas or
chapatis idli dosa no they are all made
up of some kind of cereals whether it is
rice so or it could be weed and they are
all carbohydrate rich food if you talk
about fats so fats also provide energy
so when you compare them with
carbohydrates you will see that fats
provide a lot more energy when compared
to the same amount of carbohydrates so
if you compare 10 grams of carbohydrate
with 10 grams of fats so the 10 grams of
fat is going to give you a lot more
energy than the same 10 gram of
carbohydrates so fast
they provide more energy they can
provide energy almost instantly very
quickly they can provide you energy so
these are the food items like butter
Winky oil fried food
maybe finger fries or any kind of right
thing you talk about France all of these
they are a rich source of fats you talk
about the fast food like pizza burger
they also have a lot of cheese and
butter which are rich source of fats so
if you look at both carbohydrates and
fats they both provide energy because of
that these indictments which are rich in
carbohydrates and fats they are termed
as energy giving forms because their
primary job is to provide energy to our
body so whether you talk about rice or
bread or chapati or cereals G butter
cheese they are all energy giving foods
now next we will talk about proteins so
what is the significance of protein so
proteins the some of the common food
items like pulses are a very rich source
of proteins and the fishes and meat are
also rich source of protein along with
milk so proteins help in growth and
repair of tissues of the body
now when you look at the composition of
the body of any living organism you see
that so like when when you think of a
building what makes a building a huge
number of bricks make a building right
so when you think of a building what
makes this building large number of
dicks similarly when you look at our
body so body of any living organisms are
made
of cents so these cells are building
blobs of our body and group of cells
unite together to form tissues and the
growth of these tissues are repair of
these tissues that happens only with the
help of proteins so tissues are nothing
but they are group of cells so if there
are no proteins inside our body the
tissues would not grow and if the
tissues would not grow what will happen
the overall growth of the body will also
stop right it is something like if you
do not have the bricks will you ever
have a building of course not so
proteins are very critical they not only
helping growth and repair of issues they
also help in transport processes now
when we say transport processes you can
think of hormones enzymes which are
secreted in our body at one part and
then they are carried to some other part
so these hormones enzymes these are
nothing but proteins in fact when you
talk about the transport functionality
of proteins
another example that comes to our mind
is go global
hemoglobin is a component which is
present in our blood and it helps to
transport substances from one place to
another so and hemoglobin is nothing but
a protein so all these food items which
are rich in proteins whether it is fun
cells or fish or meat oil do they are
called as bodybuilding foods because
they do not directly provide us any
energy but they help to build our body
because if these tissues are not theirs
our body formation would have not
happened and for growth and repair of
issues routines egg so proteins help in
building our bottle socks the foods
items rich in proteins are all body
