The function of protein is to build and repair body cells. Every cell in the human body needs protein.
List 5 kinds of cells you will need protein to help build:
Proteins are made of building blocks called amino acids. When you eat a protein, you take apart its
amino acids, and rearrange them to build the new proteins you need. There are some amino acids you
can make, but some you cannot make, and must get from the proteins you eat. The amino acids you
must get from proteins you eat are called __________________ amino acids
Protein comes from animal foods, or from the seeds of plants Proteins that come from animal foods
are complete. They provide al l the essential amino acids. Draw 3 foods that are complete proteins.
Proteins that come from the seed part of the plant are incomplete.
Draw 3 incomplete proteins.

Nuts & Seeds
To be able to use incomplete proteins, you
need to combine them with another
protein that provides the missing amino
acids. You can combine foods from the
grain group with legumes (things that grow in
a pod, like beans or peanuts) or nuts from the
meat group. You can combine nuts with
legumes. Or you can complete any
incomplete protein with a complete
protein. (Pairs would need to be eaten the
same day to be able to work together.)
For each of the incomplete
proteins you drew above, write in
another incomplete protein that
would complete it.
Americans generally get plenty of protein. Our problem is to make sure we are making healthy

Brian is making dinner for his girlfriend tonight. He stopped on the way home from his classes, and
picked up flowers, fresh fish, and other ingredients for the dinner. Then he went shopping for a new
shirt, got a hair-cut, and picked up his dry cleaning. At home, he put the fish on the cutting board with
his salad ingredients, set the table, and went to take a short nap. He woke up rested and ready to start.
He dipped the fish in batter and deep-fried it. He made salad, baked potatoes, and put a frozen pie in
the oven to bake. He served the fish with sliced lemon, instead of a fatty sauce. After dinner he put
all the leftovers in the refrigerator quickly, before leaving to go dancing.
