Am I Really What I Eat?

Be prepared to discuss with your group
What you will learn in this reading guide:
Now that we understand the many different types of organisms that make up our food, if we looked at our food
and at ourselves under the microscope we would see that they and we are made up of cells – sometimes trillions
of them! If we looked even closer, we would see that these cells are also made up of even smaller structures
that help the cell to do all of the functions it needs to stay alive and maintain the organism. In this reading guide
we learn more about the three major types of cells that make up our food and our bodies and about their cellular
structures.

Critical Thinking: Is the information that you just found out evidence for (supporting)
or evidence against (refuting) the claim, “You are what you eat?” What other
information do you think we still need to know in order to explain this claim?
