required to maintain one’s automatic body
functions, such as hair growth.

7.02 NUTRITION
What are the Nutrients?


Nutrients – products that come from foods that help
the body grow and function.
There are 6 Nutrients:
-Carbohydrates
-Proteins
-Fats
-Vitamins
-Minerals
-Water
What Is Nutrition?
-The study of
how your
body uses
food.
What is a Nutrient?
A chemical substance in food that
helps maintain the body.
Some provide energy, build cells
and tissues, or regulate bodily
processes.
No single food supplies all the
nutrients the body needs to
function.
 Vitamins
 Minerals
 Water
 Protein
Carbohydrates
 Fats
Sugars
Starches
Fiber
Carbohydrates


1)
2)


Carbohydrates are the body’s main source of
energy.
There are two kinds of carbohydrates:
Simple Carbohydrates = Sugars
Complex Carbohydrates = Starches, Fiber
Simple Carbohydrates are found in fruit, vegetables
and milk.
Complex Carbohydrates are found in breads, cereal,
pasta, rice, dry beans, potatoes and corn.
Protein



Proteins are nutrients used to build, maintain, and
repair body tissues.
Made up of amino acids – chemical compounds
Your body makes all but 9 of the amino acids. Those
9 are called essential amino acids.
Complete proteins = have 9 essential amino acids
(animal sources)
Incomplete proteins = lack 1 or more of the essential
amino acids (plant sources)
Fats
The most concentrated form of food energy
 Two types:
1) Saturated fats – solid at room temperature
2) Unsaturated fats – liquid at room
temperatures

Vitamins
Your body requires at least
13 vitamins each day.
 Two Categories:
1) Fat-Soluble Vitamins – body can store these,
too much of these vitamins can be harmful,
examples: A, D, E, and K
2) Water-Soluble Vitamins – not stored in the
body, large doses can be harmful

Minerals and Water

Body requires at least 16 minerals daily
–


Iron, Phosphorus, Sodium, Iodine, Calcium
Carries nutrients to your cells
Carries waste from your body
Regulate your body temperature
55% - 75% of your body weight
