Some words are
bold
the first time they appear
in the text. These words are explained in the
glossary at the back of this book.
Yogurt is a
healthy food
partly because of the
microbes
that live in
it. We will find out
more about these
microbes.
What Are You Eating?
You probably think you know what is in the food you are
eating. You may be surprised, however, when you see
your food under a microscope. Microscopes allow us to
see things up close and look at them in a different way.
Under the microscope, we can see the tiny parts that
foods are made of. We can learn why foods change when
we cook them or when they spoil.
Sharing your food
The microscope also shows us that you may not be the
only one eating your food! In the refrigerator or on the
kitchen counter, tiny
organisms
(living things) may also
be munching away.
