Lesson 1 “Carbs, Fats, and Proteins”
Pages 155-161
What is nutrition?
 Nutrition is the science or study of food and the ways
in which the body uses food.
 Nutrients are substances in food that provide energy or
help form body tissues and are necessary for life and
growth.
 What are the six classes of nutrients?
 Carbohydrates, fats, proteins, vitamins, minerals, and
water
 Make sure to eat a balanced diet!
All about carbohydrates…
Why do we need carbs?
 What are -Provides
the two types
of carbohydrates?
major
source of
energy to the body
- Essential for digestion
Simple
Complex
Carbs (fiber)
Carbs
Sugars (
- May
help prevent certainStarches
glucose,
cancers
and heart disease
fructose,
lactose,
and
Fiber
sucrose)
All about fats or lipids or triglycerides…
Unsaturated
Fatsfat?
Cholesterol
Why do
we need

body’s • Needed to make
good for you
• Mostly from animal
vitamin D, cell

under
foods
• More common
in control membranes and
• Also, coconut and- Need plants
to make hormones certain hormones
palm oil
• LDL = bad
• Tend to be liquid at

• Too much of this - Forms

Saturated Fats
weight gain
and peanut oil
• HDL = good
cholesterol and
helps reduce risk of
heart disease
All about
proteins…
Why do we need proteins?
 Proteins are made up of chains of molecules called amino
-Your muscles, skin, hair and
nails are
mostly
upthe
ofbody
 Twenty different
amino
acidsmade
make up
 9 of the
amino acids cannot be made by our bodies (essential amino
protein
acids)
- Makes hormones
 Protein comes from both animal and plant foods
-Makes enzymes
 Animal proteins contain all the essential amino acids so
- Makes
antibodies
animal proteins
are called
complete proteins
acids
 Most plant proteins have smaller amounts of some of the
essential amino acids so these proteins are called
incomplete proteins
 You must have all the essential amino acids to be healthy

You will see a food on the
following 10 slides
If you think a food is more
than one nutrient group, you
might be right!
It is your task to label it
correctly using the following
key
At the end, we will review
the correct answers
