In today's video, we're going to talk about:
nutrition.

So, we're going to get a little introduction
into how to maintain a proper diet, what you're eating,

what you should eat, what you shouldn't
eat, how much you should eat, etc.

And we're going to especially look at the
different types of nutrients that you should

put into your body if you want to grow, if
you want to maintain, if you want to lose

So, we're going to start with the basic process.

We're going to look at these two verbs: "ingest"
and "digest".

So, when we're talking about nutrition, we're
talking about what you're taking into your body.

So, when you ingest something, when you ingest
nutrients, you are swallowing them or absorbing them.

So, "swallow" basically means chew and swallow.

So, "chew" is break down the food in your
mouth, and then you swallow it; you take it in

For example, we absorb vitamin D from the
sun through our skin.

So, you can absorb or swallow - means you're
ingesting your nutrients.

In your stomach, your stomach produces juices—they're
mostly acids—that break down the food and

separate it into its different components
that can then be absorbed in the intestines.

So, the intestines are the long tubes that
go back and forth from your stomach until

the waste comes out, and inside all the good
nutrients get absorbed into the blood, and

pushed around to all the parts of the body
that need them.

So, let's look specifically at the nutrients
that you're going to need.

Now, first thing you need to know about nutrients are...

Is that they are not synthesized naturally
by the body.

So, the body produces a lot of the things
it needs, but some things it just can't synthesize;

it can't put together to create a new nutrient.

So, these nutrients need to be ingested; they
need to be put into your body, basically.

And we have: Carbohydrates, proteins, fats,
vitamins, and minerals.

You can live without carbohydrates, but you
can't live without these nutrients.

So, "carbohydrates"-we call them "carbs" for
short-these are the nutrients that provide

your body energy, especially for your brain.

They come from fruits and vegetables, grains...

So, for example, bread, which comes from wheat
or whatever other kind of grain, has a lot

Comes from sugars, and starches, like rice,
etc.

So, all of these give your body a lot of energy.

Now, you also get energy from the other minerals...

From the other nutrients as well, but carbohydrates
are a very good source.

The problem is they can also lead to weight
gain, if you don't control the intake.

"Proteins" are the nutrients that help create
and build tissues and muscles in your body.

So, when a child is growing and getting bigger,
it's the proteins that help create that growth.

It's good for bones, and muscles, and tissues,
etc.

Proteins are made of amino acids, which are
the building blocks of protein, and there

And these days you can take pills specifically
with the amino acids that you want for specific things.

So, nowadays, you see a lot of guys or girls
- big, big muscles, and you think: "Oh, steroids."

Not necessarily; they could just be taking
a lot of amino acids, and exercising a lot,

and growing their muscles and looking much
bigger.

So, proteins are basically the building blocks.

"Fats" are the nutrients that store energy.

So, if you eat too many carbohydrates, the
fats will store that energy as sugar, and

When a person is a little bit heavy, we sometimes
say: "Fat".

It's a bit of a misleading word, but that's
what happens - you're storing too much energy.

And you have different types of fatty acids.

Now, fats, as we said, they're essential;
they're necessary nutrients, which means fat

You should eat fatty foods, but there are
different types of fats and some of them you

So, when we're talking about fats, we're talking
about mono-unsaturated fats or poly-unsaturated

They're in meat, they're in fish, they're
in fruits and vegetables - you need these.

But, again, you don't want to overdo anything.

Like, I'm not getting into the medical details
of the difference between saturated and unsaturated.

It's something about their bonds and the hydrogen
molecules - don't worry about that.

If you want to know, you could do some research.

For now, things like nuts and certain oils,
and fish, and avocado, etc. - these are all

What you should absolutely avoid are trans
fats.

Now, trans fats are fats that are basically
a byproduct of a manufacturing process.
