Nutrients
 The
food you eat is a source of
nutrients. Nutrients are defined as
the substances found in food that keep your
body functioning.
 Your

Fuel your energy.
Help you grow.
Repair itself.
Maintain basic bodily functions.

Balance is Key
For years, people held to the idea that there are “bad”
nutrients and “good” nutrients when, in fact, all nutrients play a
certain role in the body. Even those nutrients once considered
“bad” such as fats and carbohydrates perform vital functions in
the body and if one consumes too many “good” nutrients such as
vitamins or minerals there can be harmful results, as well.
These three are the framework of the USDA
MyPlate:
4

Balance - Eat foods from all groups of the USDA MyPlate.

Variety - Eat different foods from each food group.

Moderation
- Eat smaller portions of foods from each

group.

Water

Did you know?


1/2 to 3/4 of the human body consists of water!
Functions in the Body:




Water carries nutrients to your cells and carries waste
from your body.
Regulates body temperature.
Dissolves vitamins, minerals, amino acids and other
nutrients.
Lubricates joints.
It is recommended that teens drink 6-8 glasses (8 fl.oz each) of water each day.
This is in addition to around 4 cups of water you get from food each day.


All beverages or fluids are a source of water.
Solid Foods:






Lettuce, celery, and other crisp vegetables are composed of
90 percent or more water.
Protein-rich foods such as meat, fish, or chicken may contain
as much as one-half to two-thirds their weight in water.
Grain products, which don’t seem watery at all, may be up to
one-third water.
Fats, such as butter or margarine, and sugar are
among the foods that contain the least water.
Some water, 1-2 cups per day, comes from inside our
bodies as a byproduct of energy metabolism.
It is important to be aware of fluid intake. Water from
drinking fluids is needed. Besides plain water, juices,
milk, or other beverages boost fluid intake.

Meat, fish,eggs, poultry, dairy products,

vegetables also contain small amounts of protein.)
Provides energy.
Help to build, maintain, and repair body tissues.
Proteins are made up of chemical compounds
called amino acids. There are 20 amino acids.
©2002 Learning Zone Express
Amino Acids
Of the 20 amino acids, the human body
is capable of producing 11 of them.
The other 9 called, “Essential Amino Acids”
must be supplied by food sources.

Two types of Protein:

Complete Proteins:
•
•

Contain all 9 essential amino acids.
They are found in animal sources.
Incomplete Proteins:
Lack one or more of the essential amino acids.
• They are found in plant sources.
The best way to give the body complete proteins is to eat a wide

Cholesterol
- A fat-like substance that is part of every cell of the body.

Function in the Body:




30
Helps the body make necessary cells including skin, and
hormones.
Aids in digestion.
The human body manufactures all the cholesterol it needs.
You also get cholesterol from animal food products you eat.
Cholesterol can’t dissolve in the blood. It has to
be transported to and from the cells by carriers
called lipoproteins. Low-density lipoprotein, or
LDL, is known as “bad” cholesterol. High-density
lipoprotein, or HDL, is known as “good”
cholesterol. These two types of lipids, along with
triglycerides make up your total cholesterol.

LDL (Bad) Cholesterol
When too much LDL (bad) cholesterol circulates in the
blood, it can slowly build up in the inner walls of the arteries
that feed the heart and brain. If a clot forms and blocks a
narrowed artery, heart attack or stroke can result.
HDL (good) Cholesterol
High-density lipoprotein (HDL) cholesterol is known as
“good” cholesterol HDL carries cholesterol away from the
arteries and back to the liver, where it's passed from the
body.
Triglycerides
Triglyceride is a form of fat made in the body. Elevated
triglycerides can be due to overweight/obesity, physical
inactivity, cigarette smoking, excess alcohol consumption
and a diet very high in carbohydrates (60 percent of total
calories or more).
