CARBOHYDRATES
If we eat more carbohydrates
than are needed for energy, the
extra is stored in the liver or in
the tissues as fat.
The 2 types of Carbohydrates
a) SIMPLE CARBS = Natural &
Refined
SUGARS
a) COMPLEX CARBS = STARCHES
Complex starches will BREAK DOWN
into simple sugars.
Simple Carbohydrates
Simple carbohydrates are quick energy
sources.
They come from sugar.
They do not usually supply any other
nutrients or fiber.
Examples of Simple Carbohydrates

Soft Drinks
Cookies
Jam
Honey
Syrup
Sugar Candy
Complex Carbohydrates
Complex carbohydrates
break down into simple
sugars in the digestion
process.
This process is what gives us
longer lasting energy
Complex Carbohydrates
Complex carbohydrates come from
starchy foods such as whole grains,
flour, seeds, nuts, vegetables and fruits.

Carbohydrates Include
Glucose or blood sugar is the basic

things. Found in fruits, veggies,
grains
Sucrose or table sugar is made from
sugar beets or sugar cane.
Fructose is sugar found in fruit, honey
and vegetables.
Maltose is grain starch broken down
into sugar.
Lactose is milk sugar.
How do you know if a
food has added sugar?
Check
out the Food Label:
Total Carbohydrate (g): Dietary Fiber,
Sugars, Other Carbohydrates (Comp
List of ingredients: sugar, juice, molasses,
honey, maple syrup, corn syrup,

Create a poster about the amounts of
sugar in different drinks.
 You need to represent 6 drinks on your

 Measure out the correct amount of sugar
and make your own “sugar packets”
 Cut out the pictures and food labels of
the drinks you chose and glue them on
