Protein
The body’s building blocks
Remember!
1.
Proteins provide 4 calories per gram.
Proteins
=4
Carbs=4
Fats and
Oils=9
ENERGY!
2. The main function of protein is to build and repair
body tissues.
• If carbohydrates and fat are not available, your
body will use protein. Is this a good thing?
3. If we consume too many proteins, our body
converts protein to fat.
4. You must eat protein daily to replace the wear
and tear on the body tissues.
5. We get most of our protein from the Protein
Food Group.
6. It is recommended that we choose 8 oz. of
seafood products in the place of some meat and
poultry every week.
Functions of Proteins
Amino Acids
7. Amino acids are the “building blocks” of which new
proteins are made.
-There are 22 different amino acids
-But 9 are the essential amino acids.
8. Essential means that your body MUST have them.
Complete Proteins
9. Complete proteins
contain all 9 of the
essential amino acids.
10. Complete proteins
come from ALL
animal food sources.
11. Tofu (from soybeans) is
the only complete protein
from a plant source.
Incomplete Proteins
12. Incomplete proteins do NOT contain all of the
essential amino acids.
13. Incomplete proteins come from plant food
sources.
14. Examples of incomplete proteins could be:
Grains
b. Beans
c. Nuts/Seeds
d. Rice
e. Wheat
a.
Complementary Proteins
15. Incomplete proteins can be combined to
create a complementary protein.
16. Complementary Proteins are a grain
combined with any nut, seed or legume.
Any other
examples you
can think of?
HINT!
By adding a small amount of any animal
protein, you create a complete protein:
• Casserole with meat
• Salad with beans and
egg
• Yogurt and granola
• Bean and cheese
burrito
• Cereal and Milk
• Macaroni and cheese
Protein Deficiency
-Leads to Kwashiorkor in children
Happens mostly in impoverished countries
where there is a lack of protein rich foods.
-It also can lead to stunted growth.
Protein deficiency in adults could lead to:
-Anemia, infections, and Marasmus
the Greek word for “dying away”

Vegetarian
• Eats foods from plant sources, and some
animal products.
• Vegetarian can add protein to diet with:
Eggs
Milk
Cheese
Plants
Vegan
• Individuals that eat foods only from plant
sources.
vegetable oil
soy
plants
• Must do complementary protein combos to
receive adequate protein.
