• 15% of your daily calories should
come from PROTEINS.
• 1g of proteins= 4 calories.
• If your snack has 3 grams of
proteins, how many calories come
from protein?
Proteins are mainly used in our
bodies for:
• Growth (especially children, teens,
pregnant women)
Muscles &
• Tissue repair- building and repairing Cells
• Energy if other energy sources
are not available.
If you do not eat enough
carbohydrates and fats for energy,
• Proteins have to supply the
energy instead of building and
repairing.
Sources of proteins:
• Proteins are found in ALL foods from
animal sources.
• They are also found in foods from plant
sources.
Most Americans
consume too much
protein which is then
stored as fat. Why?
• We eat too much RED
meat!
Amino Acids
• Proteins are made up of chains of building
blocks. They are called AMINO ACIDS.
• There are 22 amino acids. Your body can
make all but 9 amino acids.
• How many can your body make?
• Amino acids that your body CAN make.
(13)
Amino acids your body CANNOT make. You
must get them from food sources.
(It is ESSENTIAL that you get them from
food.)
Complete Proteins:
• Proteins that supply all nine essential
amino acids are called COMPLETE
PROTEINS.
• All Animal Food sources are considered
complete proteins; including: meat,
poultry, fish, eggs, dairy and soy products
(EXCEPTION: only plant food source).
Incomplete Proteins:
• Lack one or more essential amino acids.
• Plant food sources are considered
incomplete proteins. Sources: nuts, fruits,
vegetables, peas and dried beans
• You must eat a variety of incomplete
proteins to get them all.
WHAT HAPPENS WHEN YOU
TAKE…
• 2 incomplete proteins and eat them
together?
