You Become What You Eat:
Antioxidants
And the Hunt for Free Radicals
This reading provides students with a somewhat simplified explanation of the terms "free radical" and "antioxidant." Since many phytochemicals have been identified as antioxidants, this explanation is important for students' understanding of phytochemicals. If you want students to investigate further, you might have them find as many references to the terms "free radical" and "antioxidant" in magazine advertisements, on food labels, etc., as possible. It might also be interesting for students to investigate the claims being made by some companies about the ability of antioxidants to cure disease and sustain good health.

Relevant National Science Education Standards
Physical Science — The atomic
and molecular nature of matter are central to understanding free radicals and antioxidants, as
is a knowledge of chemical reactions and the role of electrons in the behavior of atoms and
molecules, especially free radicals.
Science and Technology — The
reading shows how complex biochemistry can be applied to create the very simple technology of
good nutrition to prevent cancer.
Science in Personal and Social
Perspectives — Science's role in the health challenge of cancer prevention is clear from
this reading.
