>> Hello everyone. Today we begin an
0:11
exciting journey into the world of
0:13
nutrition. Food gives life to all living
0:16
beings. Over the next few slides, we'll
0:19
explore how to eat mindfully to build a
0:21
healthy body and understand why what we
0:24
eat matters so much.
0:32
Look at this school notice board. Food
0:34
is the most essential component of our
0:37
daily life, providing the sustenance we
0:39
need to survive. But being healthy isn't
0:42
just about eating anything. It's about
0:44
choosing wholesome food in moderation
0:47
that is appropriate for the season and
0:49
the place we live. Let's think about
0:51
what we've eaten this week. Have you
0:53
ever noticed that your friends might eat
0:55
very different meals than you do? Across
0:58
India, food choices vary significantly
1:01
from state to state. This wonderful
1:04
diversity is closely linked to the crops
1:06
grown locally as well as the unique
1:08
climate, [music]
1:09
culture, and traditions of each region.
1:13
Let's take a food tour. In Punjab, maize
1:16
and wheat are staples, [music]
1:17
giving us the famous maki roti. Travel
1:21
south to Carnotica and you'll find rice
1:23
and raggi based dishes like idli and
1:25
dosa. Meanwhile, in Manipur, traditional
1:28
meals often include rice and unique
1:31
green onion curries like uti. Our diet
1:34
truly reflects our geography. Cooking
1:37
has changed so much over time. Earlier,
1:40
most cooking was done using a
1:42
traditional stove called a chula and
1:44
grinding was done manually with a stone
1:47
sila. Today, technological developments
1:50
have given us gas stoves and electrical
1:52
grinders for ease. These changes in
1:55
culinary practices are driven by better
1:57
transportation and modern technology.
2:00
What exactly is inside our food? It
2:03
contains components called nutrients.
2:06
These are the magic ingredients that
2:08
provide us with energy, support our
2:10
growth, repair our body tissues, and
2:12
protect us from various diseases. Major
2:15
nutrients include carbohydrates, fats,
2:18
proteins, vitamins, and minerals.
2:22
First, let's look at carbohydrates, our
2:25
primary energy source. Found in cereals,
2:28
potatoes, and fruits like bananas. They
2:31
keep us moving. Simple carbohydrates
2:33
like glucose provide instant energy,
2:36
which is why you see marathon runners
2:38
drinking glucose water during a race to
2:40
keep their energy up. Next are fats.
2:43
These provide stored energy and help
2:45
keep us warm. We get them from plants
2:48
like nuts and seeds or animals like ghee
2:51
and butter. Did you know polar bears
2:54
survive long winters without eating by
2:56
using the thick layer of fat accumulated
2:58
under their skin as an energy source
3:03
for growth and repair? We need proteins,
3:06
the bodybuilding foods. Sports persons
3:08
need them in large quantities to build
3:10
muscle. We get proteins from plant
3:13
sources like pulses and beans and animal
3:16
sources like milk, eggs, and fish. Even
3:19
edible mushrooms are a great source of
3:21
protein.
3:22
Now, let's talk about protective foods.
3:26
Vitamins and minerals are required in
3:28
only small amounts, but they are
3:30
essential for protecting our body from
3:32
diseases and keeping us healthy. [music]
3:34
They strengthen our body and help our
3:36
heart and eyes function properly.
3:40
Vitamin A keeps our eyes and skin
3:42
healthy. Without it, one might suffer
3:45
from loss of vision in the dark. Vitamin
3:48
B1 is also crucial as it keeps the heart
3:51
healthy. A deficiency in B1 can lead to
3:54
a disease called berry berry which
3:56
causes swelling and trouble breathing.
3:59
History teaches us the power of vitamin
4:02
C. Scottish physician James Lind
4:04
observed that sailors on long voyages
4:07
suffered from bleeding gums, a disease
4:09
called scurvy. He found that those who
4:11
ate lemons and oranges recovered
4:14
quickly. Vitamin C found in citrus
4:17
fruits and amla is essential for helping
4:19
our body fight diseases.
4:22
For strong bones and teeth, we need
4:24
vitamin D and calcium. Vitamin D is
4:27
unique because our body can produce it
4:29
naturally when our skin is exposed to
4:31
sunlight. Without these, bones can
4:34
become soft and bent leading to a
4:36
deficiency disease known as ricketetts.
4:39
Finally, we have essential minerals like
4:42
iodine and iron. Iodine prevents goer
4:46
which causes swelling in the neck. Iron
4:48
is a key component of our blood. If we
4:51
lack iron, we may develop anemia leading
4:53
to weakness and shortness of breath. Now
4:56
that we know the building blocks, let's
4:58
learn [music] how to test for them.
5:01
Welcome to the second part of our
5:03
lesson. [music] Now that we understand
5:05
nutrients, it's time to get practical.
5:08
We'll learn how to identify these
5:09
nutrients in our food and discover why
5:11
eating locally is not just healthy for
5:14
us, but also for our entire planet. Our
5:18
body needs more than just nutrients. It
5:20
needs dietary fiber, also known as
5:23
ruffage. While it doesn't provide
5:25
nutrients, it is essential for helping
5:28
our body get rid of undigested food and
5:31
ensuring the smooth passage of waste.
5:33
You can find it in fruits, vegetables,
5:36
and whole grains. Water is another vital
5:39
part of our diet. Even though it
5:41
provides no nutrients, it helps our body
5:43
absorb nutrients from the food we eat.
5:46
It also acts as a cleaning system,
5:48
removing waste through sweat and urine
5:51
to keep us functioning perfectly.
5:54
Meet Kolithther Gopalan, the scientist
5:57
who initiated nutrition research in
5:59
India. He analyzed over 500 Indian foods
6:02
to identify nutritional gaps. His work
6:05
led to the midday meal program, now
6:08
called PM Potion, which provides
6:10
balanced food to millions of school
6:12
children nationwide.
6:14
You don't always need a fancy lab to
6:16
find nutrients. We can use simple tests
6:19
to detect starch, fats, and proteins
6:22
right in our classroom. These
6:24
investigations help us understand the
6:26
hidden components in the items we eat
6:28
every day.
6:30
To test for starch, a type of
6:32
carbohydrate, take a food sample, like a
6:35
slice of potato, and add a few drops of
6:37
diluted iodine solution. If the food
6:40
turns blue black, it confirms that
6:42
starch is present. It's a simple and
6:45
very effective way to find energy-giving
6:47
starch.
6:49
Testing for fats is even easier. Wrap a
6:52
small amount of food in paper and press
6:54
it. If an oily translucent patch
6:57
appears, one that lets light shine
6:59
through faintly, that food contains fat.
7:02
We see this often with butter, oil, or
7:05
crushed nuts. For proteins, we need two
7:08
chemicals: copper sulfate and costic
7:11
soda. After making a paste of the food
7:14
and adding these solutions, watch for a
7:16
color change. If the mixture turns
7:18
violet, you found protein.
7:21
Interestingly, foods like peanuts can
7:23
test positive for both proteins and
7:26
fats. What is a balanced diet? It is a
7:30
diet that contains all essential
7:32
nutrients, roughage, and water in the
7:34
right amounts for health and growth.
7:36
Requirements vary based on your age,
7:39
gender, and how active you are, but the
7:41
goal is always to provide the body
7:44
exactly what it needs to thrive.
7:47
Beware of junk food. These items are
7:50
high in calories from sugar, and fat,
7:52
but provide very little protein,
7:54
vitamins, or minerals. Consuming them
7:57
frequently can lead to obesity and other
7:59
health problems. Remember Dr. Poshida's
8:02
statement, health is the ultimate
8:04
wealth.
8:07
Let's make smart choices. If you compare
8:10
100 gram of potato wafers to 100 g of
8:13
roasted chana, the chana is far
8:16
healthier. It has much more protein and
8:18
dietary fiber and way less fat. Choosing
8:21
nutrient-dense snacks instead of junk
8:24
food is a great way to take care of your
8:26
body.
8:27
To ensure safety, the FSSAI regulates
8:31
food quality in India. You might also
8:33
see fortified foods where nutrients like
8:36
iodine or iron are added back during
8:39
processing to improve nutritional
8:41
quality. These are simple ways our
8:43
government helps fight widespread
8:45
nutrient deficiencies. Have you heard of
8:48
millets? These native Indian grains like
8:51
joar, bodra and ragi are called
8:54
nutriereals. They are highly nutritious
8:57
providing vitamins, minerals like iron
8:59
and calcium and plenty of fiber. They're
9:02
easy to grow and contribute
9:04
significantly to a balanced diet.
9:08
Food travels a long journey. The
9:11
distance food travels from the producer
9:13
to you is called food miles. For a
9:16
simple chapati, it involves farming,
9:18
harvesting, threshing, grinding, and
9:21
transport. Reducing food miles helps cut
9:24
pollution, supports our local farmers,
9:26
and ensures our food is as fresh as
9:29
possible. Finally, we must practice
9:32
ethical eating. Choosing locally grown
9:35
plant-based food is healthy for us and
9:38
good for the environment. Most
9:40
importantly, never waste food. Think of
9:43
the immense effort our farmers put into
9:45
every grain. Take only as much as you
9:48
can consume. Eat healthy, share, and
9:51
respect your food.
